Sportmotorische Leistungsfähigkeit und schulische Leistung – Zum mediierenden Effekt der exekutiven Funktionen

Die sportmotorische Leistungsfähigkeit (SMLF) gilt in jüngster Zeit als ein Prädiktor für schulische Leistung (SL) (Diamond, 2013). Um die Frage zu beantworten, wie denn zwei auf den ersten Blick so distale Merkmale zusammenhängen sollen, werden unterschiedliche erklärende Variablen diskutiert, wobei die kognitive Stimulationshypothese die exekutiven Funktionen (EF) als mediierende Variable im Zusammenhang zwischen SMLF und SL postuliert. Die Annahme hierbei ist, dass die mit komplexen motorischen Kontrollprozessen einhergehende kognitive Beanspruchung bei einem wiederholten Ausführen von nicht-automatisierten sportbezogenen Handlungen zu einer Aktivierung und somit Förderung der EF führt (Best, 2010). Der mediierende Effekt der EF im Zusammenhang zwischen der SMLF und der SL wird seit einigen Jahren in der Literatur diskutiert und wird im Folgenden innerhalb einer längsschnittlichen Untersuchung getestet. Im Rahmen der Studie SpuK wurden 237 Primarschulkinder (52.3% ♀; 11.31 ± 0.62 Jahre) zu drei Messzeitpunkten in ihrer SMLF (T1) und ihren EF (T2) getestet. Zur Ermittlung der SMLF wurden drei sportmotorische Tests in den Bereichen Koordination, Ausdauer und Schnellkraft durchgeführt. Die EF Inhibition, kognitive Flexibilität und Arbeitsgedächtnis wurden computerbasiert über den N-Back- und Flanker-Test operationalisiert. Zusätzlich wurde die SL (T3) mittels objektiver Schulleistungstests erhoben. Um die Hauptfragestellung zu prüfen, wurde eine bootstrapping basierte Mediationsanalyse in AMOS durchgeführt. Das Strukturgleichungsmodell (2 (22, N=237)=30.357, p=.110; CFI=.978) weist eine zufriedenstellende Anpassungsgüte auf. Erwartungsgemäss zerfällt der Zusammenhang innerhalb des Mediationsmodells zwischen der SMLF und der SL, alsbald die EF ins Modell aufgenommen werden (β=.16, p= .634). Sowohl der Zusammenhang zwischen der SMLF und den EF (β=.38, p= .039), als auch der Zusammenhang zwischen den EF und der SL fallen signifikant aus (β=.91, p=.001) und ergeben dabei eine volle Mediation über den indirekten (p=.021) und totalen Effekt (p=.001). Die vorliegenden längs-schnittlichen Daten bestätigen den Zusammenhang zwischen SMLF und SL bei einer Mediation über die EF und bestätigen somit die aus querschnittlichem Design stammenden Resultate von van der Niet et al.

Estudo de associação entre déficits de reconhecimento de emoções em faces, flexibilidade mental e adequação social, em pacientes com transtorno bipolar do tipo I eutímicos, comparados com controles normais

Introdução: O objetivo do estudo foi investigar se há associação entre déficits na capacidade de reconhecimento de emoções faciais e déficits na flexibilidade mental e na adequação social em pacientes com Transtorno Bipolar do tipo I eutímicos quando comparados a sujeitos controles sem transtorno mental. Métodos: 65 pacientes com Transtorno Bipolar do tipo I eutímicos e 95 controles sem transtorno mental, foram avaliados no reconhecimento de emoções faciais, na flexibilidade mental e na adequação social através de avaliações clínicas e neuropsicológicas. Os sintomas afetivos foram avaliados através da Escala de Depressão de Hamilton e da Escala de Mania de Young, o reconhecimento de emoções faciais através da Facial Expressions of Emotion: Stimuli and Tests, a flexibilidade mental avaliada através do Wisconsin Card Sorting Test e a adequação social através da Escala de Auto- Avaliação de Adequação Social. Resultados: Pacientes com Transtorno Bipolar do tipo I eutímicos apresentam uma associação de maior intensidade comparativamente aos controles entre o reconhecimento de emoções faciais e a flexibilidade mental, indicando que quanto mais preservada a flexibilidade mental, melhor será a habilidade para reconhecer emoções faciais Neste grupo às correlações de todas as emoções são positivas com o total de acertos e as categorias e são negativas com as respostas perseverativas, total de erros, erros perseverativos e erros não perseverativos. Não houve uma correlação entre o reconhecimento de emoções faciais e a adequação social, apesar dos pacientes com Transtorno Bipolar do tipo I eutímicos apresentar uma pior adequação social, sinalizando que a pior adequação social não parece ser devida a uma dificuldade em reconhecer e interpretar adequadamente as expressões faciais. Os pacientes com Transtorno Bipolar do tipo I eutímicos não apresentam diferenças significativas no reconhecimento de emoções faciais em relação aos controles, entretanto no subteste surpresa (p=0,080) as diferenças estão no limite da significância estatística, indicando que portadores de transtorno bipolar do tipo I eutímicos tendem a apresentar um pior desempenho no reconhecimento da emoção surpresa em relação aos controles. Conclusão: Nossos resultados reforçam a hipótese de que existe uma associação entre o reconhecimento de emoções faciais e a preservação do funcionamento executivo, mais precisamente a flexibilidade mental, indicando que quanto maior a flexibilidade mental, melhor será a habilidade para reconhecer emoções faciais e melhorar o desempenho funcional do paciente. Pacientes bipolares do tipo I eutímicos apresentam uma pior adequação social quando comparados aos controles, o que pode ser uma consequência do Transtorno Bipolar que ratifica a necessidade de uma intervenção terapêutica rápida e eficaz nestes pacientes

O cérebro sócio-musical: estudo de uma experiência de educação musical

A prática musical tem efeitos positivos no desenvolvimento humano, envolvendo aspectos cognitivos, emocionais, motivacionais e sociais, que implicam em alterações no processamento cerebral. O número de Programas de Educação Musical (PEMs) com enfoque em populações jovens em vulnerabilidade social tem crescido no Brasil e no mundo. Dessa maneira, torna-se importante a realização de estudos que verifiquem os efeitos de PEMs no desenvolvimento destas populações. O objetivo do presente estudo é investigar os impactos de uma experiência de um PEM sobre os aspectos psicológicos de seus estudantes, mais especificamente a autoestima, as habilidades sociais e o funcionamento executivo. A coleta de dados foi realizada em um PEM da cidade de Ribeirão Preto SP e em duas escolas regulares de ensino, uma particular e outra da rede pública. Participaram do estudo 69 crianças e adolescentes com idades entre 10 e 17 anos, divididos em três grupos, a saber: Grupo Iniciante (GI), composto por alunos com até 12 meses de matrícula no PEM; Grupo Experiente (GE), composto por alunos com mais de 24 meses de matrícula no PEM; e Grupo Controle (GC), constituído por participantes sem qualquer envolvimento com aprendizado musical. Cada grupo foi composto por 23 estudantes. Os três grupos de participantes responderam aos seguintes testes psicológicos: Escala de Autoestima de Rosenberg (EAR), Matson Evaluation of Social Skills with Youngsters (MESSY) e Teste de Stroop. Também foram realizadas entrevistas semi-estruturadas com todos os estudantes dos grupos GI e GE, dez estudantes do PEM que não compuseram nenhum grupo por não possuírem o pré-requisito de tempo de matrícula exigido, seis responsáveis legais dos estudantes e doze profissionais do PEM. As entrevistas tiveram a função de fornecerem relatos verbais a respeito dos impactos percebidos nos estudantes pelo envolvimento com o PEM. Os dados dos testes psicológicos foram analisados através dos testes estatísticos ANOVA, Mann-Whitney e t de Student e as entrevistas foram analisadas através da investigação qualitativa em educação. As análises dos testes psicológicos mostraram que os GI e GE não possuem diferenças entre si para nenhuma das variáveis de estudo. O GC apresentou escores inferiores aos GI e GE para a Autoestima e escores superiores para Solidão e Ansiedade Social, indicando que o envolvimento com o PEM pode acarretar em ganhos nessas habilidades. A partir da análise das entrevistas foram construídas três categorias de codificação relacionadas a impactos comportamentais do envolvimento com o PEM, a saber: relacionamento interpessoal, desenvolvimento de habilidades intrapessoais e envolvimento com música e desenvolvimento humano na perspectiva de profissionais e responsáveis legais. A análise das entrevistas indicou que a participação no PEM está relacionada a impactos positivos na autoestima, habilidades sociais e funcionamento executivo dos participantes. Os resultados foram discutidos buscando interrelaciona-los de maneira a integrar os dados colhidos por meio dos testes psicológicos e através das entrevistas. Conclui-se que a participação em PEMs com enfoque no resgate social de populações vulneráveis possui influência no desenvolvimento de crianças e adolescentes, indicando que o uso da educação musical caracteriza uma importante estratégia de intervenção social.

Relationship Maintenance in Couples with a Partner Who Has Attention Deficit Hyperactivity Disorder

The body of research on the relationship functioning of adults with attention deficit hyperactivity disorder (ADHD) is relatively small; the aim of the present study is to advance our understanding of this topic. It has been estimated that three to ten percent of children and one to five percent of adults have impairing symptoms of ADHD, which is a total of 4 million children and 4-5 million adults in the U.S. (Wender, 2000). A recent prevalence study found that approximately 4.4% of adults in the U.S. meet the criteria for a diagnosis of ADHD (Kessler et al., 2006). Children with ADHD show innate temperamental characteristics, usually inattentiveness, distractibility, impulsivity, restlessness, demandingness, hyperreactivity, low tolerance for frustration, temperoutbursts, bossiness and stubbornness, and mood lability, along with an innate proclivity for academic underachievement. It has been estimated that one- to two-thirds of children with ADHD have symptoms that continue into adulthood, and for 40-50% of these adults, these symptoms are serious enough to cause impairment in functioning (Everett & Everett, 1999; Wender, 2000). Research suggests that the majority of cases are transmitted genetically, but some may be due to exposure to environmental toxins such as lead. Consumption of excess sugar or allergies to food may exacerbate or mimic ADHD symptoms in some children, but they are not a cause of ADHD (Wender, 2000). One hypothesized cause of the symptoms associated with ADHD is a deficit in the brain's executive functioning (Barkley & Gordon, 2002). Executive functioning can be conceptualized as the ability to inhibit, organize, and plan behaviors. Barkley and Gordon (2002) define it as the abilityto self-direct and regulate behaviors toward future goals, including social behaviors and goals. Other research suggests that executive functioning consists of inhibition, control of interference, verbal and nonverbal working memory, emotional regulation, attention, verbal fluency, visual scanning, and processing speed. Studies have shown impairments in these areas among adults with ADHD (Barkley & Gordon, 2002; Barkley, Murphy & Kwasnik, 1996; Goldstein, 2002).

Inhibitory Control is a Rate-Limiting Factor to Preschoolers' Use of Irregular Inflection

We investigated whether children’s inhibitory control is associated with their ability to produce irregular verb forms as well as learn from corrective feedback following their use of an over-regularized form. Forty-eight 3.5 to 4.5 year old children were tested on the irregular past tense and provided with adult corrective input via models of correct use or recasts of errors following ungrammatical responses. Inhibitory control was assessed with a three-item battery of tasks that required suppressing a prepotent response in favor of a non-canonical one. Results showed that inhibitory control was predictive of children’s initial production of irregular forms and not associated with their post-feedback production of irregulars. These findings show that children’s executive functioning skills may be a rate-limiting factor on their ability to produce correct forms, but might not interact with their ability to learn from input in this domain. Findings are discussed in terms of current theories of past-tense acquisition and learning from input more broadly.

Investigation of factors related to employment outcome following traumatic brain injury: a critical review and conceptual model

Purpose : The purpose of this article is to critically review the literature to examine factors that are most consistently related to employment outcome following traumatic brain injury (TBI), with a particular focus on metacognitive skills. It also aims to develop a conceptual model of factors related to employment outcome. Method : The first stage of the review considered 85 studies published between 1980 and December 2003 which investigated factors associated with employment outcome following TBI. English-language studies were identified through searches of Medline and PsycINFO, as well as manual searches of journals and reference lists. The studies were evaluated and rated by two independent raters (Kappa = 0.835) according to the quality of their methodology based upon nine criteria. Fifty studies met the criteria for inclusion in the second stage of the review, which examined the relationship between a broad range of variables and employment outcome. Results : The factors most consistently associated with employment outcome included pre-injury occupational status, functional status at discharge, global cognitive functioning, perceptual ability, executive functioning, involvement in vocational rehabilitation services and emotional status. Conclusions : A conceptual model is presented which emphasises the importance of metacognitive, emotional and social environment factors for improving employment outcome.

Investigation of psychological and neuropsychological factors associated with clinical outcome following a group rehabilitation programme

The present study investigated neuropsychological and psychological factors associated with successful treatment outcome following a group intervention for individuals with acquired brain injury (ABI). Participants were classified into two groups (Clinically Improved and Not Improved) based upon the findings of a previous study (Ownsworth, McFarland, & Young, 2000a). A discriminant analysis was used to predict group membership on three outcome measures (Awareness and Strategy Behaviour indices of the Self-Regulation Skills Interview and the Psychosocial Dimension of the Sickness Impact Profile) between pre-assessment and post-assessment, and between pre-assessment and 6 months follow-up. Neuropsychological factors involved measures of executive functioning and psychological factors were assessed using measures of personality-related denial and coping-related denial. Overall, the results indicated that individuals with impaired executive functioning were most likely to be classified as Clinically Improved on measures of awareness, strategy behaviour and psychosocial functioning. Individuals who deny or minimise their ABI symptoms were less likely to improve their psychosocial functioning following the group intervention. Future research needs to evaluate interventions for enhancing self-regulation skills and improving psychosocial functioning for individuals who employ denial as a main strategy for coping following ABI.

Factor analysis of the self-report Dysexecutive (DEX-S) Questionnaire

The self-rating Dysexecutive Questionnaire (DEX-S) is a recently developed standardized self-report measure of behavioral difficulties associated with executive functioning such as impulsivity, inhibition, control, monitoring, and planning. Few studies have examined its construct validity, particularly for its potential wider use across a variety of clinical and nonclinical populations. This study examines the factor structure of the DEX-S questionnaire using a sample of nonclinical (N = 293) and clinical (N = 49) participants. A series of factor analyses were evaluated to determine the best factor solution for this scale. This was found to be a 4-factor solution with factors best described as inhibition, intention, social regulation, and abstract problem solving. The first 2 factors replicate factors from the 5-factor solutions found in previous studies that examined specific subpopulations. Although further research is needed to evaluate the factor structure within a range of subpopulations, this study supports the view that the DEX has the factor structure sufficient for its use in a wider context than only with neurological or head-injured patients. Overall, a 4-factor solution is recommended as the most stable and parsimonious solution in the wider context.

The impact of general intellectual ability and white matter volume on the functional outcome of patients with bipolar disorder and their relatives

Background: There is substantial evidence that cognitive deficits and brain structural abnormalities are present in patients with Bipolar Disorder (BD) and in their first-degree relatives. Previous studies have demonstrated associations between cognition and functional outcome in BD patients but have not examined the role of brain morphological changes. Similarly, the functional impact of either cognition or brain morphology in relatives remains unknown. Therefore we focused on delineating the relationship between psychosocial functioning, cognition and brain structure, in relation to disease expression and genetic risk for BD. Methods: Clinical, cognitive and brain structural measures were obtained from 41 euthymic BD patients and 50 of their unaffected first-degree relatives. Psychosocial function was evaluated using the General Assessment of Functioning (GAF) scale. We examined the relationship between level of functioning and general intellectual ability (IQ), memory, attention, executive functioning, symptomatology, illness course and total gray matter, white matter and cerebrospinal fluid volumes. Limitations: Cross-sectional design. Results: Multiple regression analyses revealed that IQ, total white matter volume and a predominantly depressive illness course were independently associated with functional outcome in BD patients, but not in their relatives, and accounted for a substantial proportion (53%) of the variance in patients' GAF scores. There were no significant domain-specific associations between cognition and outcome after consideration of IQ. Conclusions: Our results emphasise the role of IQ and white matter integrity in relation to outcome in BD and carry significant implications for treatment interventions. © 2010 Elsevier B.V.

The role of working memory in compulsive checking and OCD:a systematic classification of 58 experimental findings

Despite the large body of research regarding the role of memory in OCD, the results are described as mixed at best (Hermans et al., 2008). For example, inconsistent findings have been reported with respect to basic capacity, intact verbal, and generally affected visuospatial memory. We suggest that this is due to the traditional pursuit of OCD memory impairment as one of the general capacity and/or domain specificity (visuospatial vs. verbal). In contrast, we conclude from our experiments (i.e., Harkin & Kessler, 2009, 2011; Harkin, Rutherford, & Kessler, 2011) and recent literature (e.g., Greisberg & McKay, 2003) that OCD memory impairment is secondary to executive dysfunction, and more specifically we identify three common factors (EBL: Executive-functioning efficiency, Binding complexity, and memory Load) that we generalize to 58 experimental findings from 46 OCD memory studies. As a result we explain otherwise inconsistent research – e.g., intact vs. deficient verbal memory – that are difficult to reconcile within a capacity or domain specific perspective. We conclude by discussing the relationship between our account and others', which in most cases is complementary rather than contradictory.

The influence of neurocognitive impairment, alcohol and other drug (AOD) use, and psychosocial factors on antiretroviral treatment adherence, service utilization and viral load among HIV-seropositive adults

Among people living with HIV (PLWH), adherence to antiretroviral therapy (ART) can be affected by problems of neurocognitive (NC) impairment, stress, alcohol and other drug (AOD) abuse, and other barriers. The aims of this research were to: (1) examine factors associated with NC impairment, (2) explore relationships between psychosocial variables with ART adherence and viral load (VL), and (3) evaluate the efficacy of an evidence-based intervention in improving ART adherence, increasing service utilization, and decreasing VL. The first study (n=370) was cross sectional and used structural equation modeling to test whether AOD use, years living with HIV, and time from HIV diagnosis to seeking care were associated with poorer NC functioning. The second study (n=246) used similar methods to test the hypothesis that stress, barriers to adherence, NC impairment, poor social support, and AOD use were related to lower VL mediated by ART adherence. The third study (n=243) evaluated an evidence-based, eight-session program to improve ART adherence, reduce VL, and increase service utilization in a randomized controlled trial. Study participants were PLWH living in South Florida, 18 to 60 years old, with a history of alcohol abuse enrolled from January 2009 through November 2012. Secondary analysis of available data showed: (1) scores on interference with executive functioning increased by 0.32 for each day of marijuana use and 1.18 for each year living with HIV, but no association was found between alcohol use and NC functioning; (2) each barrier to adherence was associated with a 10% decrease in adherence to ART and a 0.42 unit increase in VL (log10) and the relationship between barriers and VL was partially mediated by ART adherence; (3) participants in the evidence-based program were more likely than the comparison group to report an undetectable VL (OR=2.25, p<0.01) at 6 months, but not 3 months, post-intervention. Psychosocial factors affect VL, but ART adherence is essential in achieving an undetectable VL in PLWH.

Perfil desenvolvimental das funções executivas em crianças de 05 a 08 anos da cidade de Natal - RN

This study aimed to establish the developmental profile of executives components in typical child development. This is a correlational cross-sectional study of predominantly quantitative. The instruments for data collection are the subtests included in the NEPSY-II Attention and Executive Functioning domain. Eighty children between 5 and 8 years of age, of both genders, students from public and private schools in the city of Natal were evaluated. The sample was divided into six-month intervals for subsequent analysis of strategies and types of errors. Analysis of variance (univariate and multivariate) and Tukey and Games-Howell post hoc tests were conducted to verify the effect of age on test performance. Subsequent correlations indicate the strength and direction of the relationship between variables. Were identified two peaks of development in the six-month interval adopted for the skills of selective attention and inhibitory control. The results indicate that there’s no significant influence of sex and type of school on the performance of the sample. The performance of preschool children (5 and 6 years) was lower than the other subgroups in most tests. Highlights the role of autoregulation discourse among preschool children during activities of greater executive demand and the abstraction resource as a resolution strategy between the older. Were identified similar development trajectories among selective attention abilities and inhibitory control. In general, there is a decrease in the number of mistakes and increase of success with the age progression. Future longitudinal research can extend the age range encompassed in this study, investigating the developmental course of executive abilities.

A relação entre transtorno da insônia e funções executivas em adultos

The insomnia disorder is defined as a difficulty initiating or maintaining sleep or waking up earlier than expected unable to return to sleep, followed by a feeling of nonrestorative and poor quality sleep, present for at least three months, with consequences on daytime functioning. Studies have shown that insomnia affects cognitive function, especially executive functions. However, researches that sought to investigate the relationship between primary insomnia and executive functioning were quite inconsistent from a methodological point of view, especially in regard to the variability of the used methods, the heterogeneity of diagnostic criteria for insomnia and the control of sleep altering drugs. In this sense, the present study aimed to investigate the relationship between insomnia and executive functions in adults. The participants were 29 people, from both genders, aged 20-55 years old. Participants were divided into three groups, one composed of 10 people with primary insomnia who used sleep medication (GIM), nine people with primary insomnia who did not use medication (GInM) and 10 healthy people who composed the control group (CG). The research was conducted in two stages. The first one involved a diagnostic evaluation for insomnia disorder through a clinical interview and the application of the following protocols: the Athens Insomnia Scale, the Insomnia Severity Index, Sleep Journal (for 14 days), Pittsburgh Sleep Quality Index (PSQI), the Stanford Sleepiness Test, depression and anxiety Beck inventories, and Lipp’s Iventory of stress symptoms for adults. After this stage, the evaluation of executive functions was performed by applying a battery of neuropsychological tests composed by the following tests: Wisconsin, Stoop Test, Colored trails Test, the Tower of London Test, Iowa Gambling Task (IGT) and WAIS III subtest digit span, which measured selective attention, inhibitory control, cognitive flexibility, planning, problem solving, decision making and working memory, respectively. The results showed that insomniacs (GIM and GInM) showed higher sleep latency, shorter sleep duration and lower sleep efficiency compared to the CG. In regard to the performance in executive functions, no statistically significant difference between groups was observed in the evaluated modalities. However, the data show evidence that, compared to GInM and GC, the performance of GIM was lower on tasks that required quick responses and changes in attention focus. On the other hand, GInM, when compared to GIM and GC, showed a better performance on tasks involving cognitive flexibility. Furthermore, impaired sleep measures were correlated with the worst performance of insomniacs in all components evaluated. In conclusion, people with the insomnia disorder showed a performance similar to healthy people’s in components of the executive functioning. Thus, one can infer that there is a relationship between primary insomnia and executive functions in adults.

Efeitos de um programa de treino cognitivo e das técnicas de higiene do sono para as funções executivas e para a qualidade de sono em idosos saudáveis

The aging process causes changes in the elderly’s sleep/awake standard impairing their cognitive abilities, particularly executive functioning, which already suffers loss by aging. The literature suggests that executive function and preserved sleep quality are key to maintaining good quality of life and independence of older people, requiring interventions to minimize the impact of losses incurred by the aging process. This study evaluated the effect of a cognitive training program and sleep hygiene techniques for executive functions and sleep quality in healthy older people. The participants were 41 healthy older adults, of both sexes, who were randomly divided into four groups: control group [GC], cognitive training group [GTC], sleep hygiene group [GHS] and training group + hygiene [GTH]. The research was developed in three stages: 1st - initial assessment of cognition and sleep; 2nd - specific intervention to each group; 3rd - post-intervention revaluation. The results showed that GTC had significant improvements in cognitive tasks flexibility, planning, verbal fluency and some aspects of episodic memory, besides gains in sleep quality and decrease on daytime hypersomnolence. The GHS improved sleep quality and daytime sleepiness as well and had significant improvements in insights capacity, planning, attention and in all evaluated aspects of episodic memory. The GTH had significant gains in cognitive flexibility, problem solving, verbal fluency, attention and episodic memory. The CG showed significant worsening in excessive daytime sleepiness in capacity planning. Thus, we conclude that cognitive training interventions and sleep hygiene strategies are useful in improving cognitive performance and quality of healthy elderly sleep.

Le profil des récidivistes en matière de conduite avec capacités affaiblies par l’alcool : une étude des caractéristiques neuropsychologiques et psychologiques des contrevenants selon leur sexe

Durant les dernières décennies, les différences intersexes en matière de conduite avec les capacités affaiblies par l’alcool (CCAA) ont suscité l’attention, alors que le comportement est en augmentation chez les femmes tandis qu’il diminue chez les hommes. Les données suggèrent que, chez les femmes, la CCAA s’associe à des caractéristiques psychologiques différentes de celles qui se retrouvent chez les contrevenants masculins (c.-à-d. davantage de problèmes liés à l’alcool et aux drogues et de psychopathologies, mais moins de recherche de sensations et de comportements délinquants). Malgré ce profil différentiel, les femmes contrevenantes de la CCAA demeurent une population hautement méconnue, particulièrement en ce qui a trait au profil des récidivistes. Alors que chez les hommes, des données émergentes indiquent que des limitations cognitives sont présentes chez les récidivistes et qu’elles constituent potentiellement un mécanisme sous-jacent au comportement, le profil cognitif des femmes récidivistes demeure inexploré. Des données exploratoires obtenues chez les contrevenantes et la documentation de champs de recherche connexes suggèrent que les femmes se distinguent notamment en ce qui concerne leur fonctionnement exécutif qui pourrait être préservé, alors que leur fonctionnement visuospatial serait déficitaire en comparaison de leurs vis-à-vis masculins. L’objectif de la présente thèse est d’approfondir les connaissances sur les caractéristiques des femmes récidivistes, ce qui permettra de mieux comprendre l’hétérogénéité de cette population et de générer des hypothèses au regard des mécanismes cognitifs sous-jacents à la répétition du comportement de CCAA. Plus spécifiquement, la thèse a pour objectif premier d’étudier les différences entre les sexes en matière de fonctionnement visuospatial et de mémoire visuelle, d’attention et de fonctionnement exécutif (c.-à-d. flexibilité cognitive, abstraction, inhibition). L’objectif secondaire consiste à comparer ces contrevenants au regard de leurs caractéristiques psychologiques (problèmes liés à l’alcool et aux drogues, impulsivité, recherche de sensations, traits antisociaux, anxiété et dépression). L’hypothèse examinée soutient que les femmes et les hommes récidivistes de la CCAA performent moins bien que les femmes et les hommes non-contrevenants en termes de fonctionnement visuospatial, attentionnel et exécutif. En outre, il est attendu que les femmes récidivistes présentent des performances inférieures à celles des hommes récidivistes en ce qui a trait aux fonctions visuospatiales. Par ailleurs, l’hypothèse prévoit que les hommes récidivistes aient des performances inférieures à celles des femmes récidivistes sur le plan exécutif et attentionnel. En matière de caractéristiques psychologiques, il est attendu que les femmes et les hommes récidivistes présentent significativement plus de problèmes liés à l’alcool et aux drogues, d’impulsivité, de recherche de sensations et d’indices de psychopathologies (tendance antisociale, dépression, anxiété) que les non-contrevenants. En outre, il est attendu que les femmes récidivistes présentent plus de problèmes liés à l’alcool et aux drogues et d’indices de dépression et d’anxiété que les hommes récidivistes. Enfin, il est attendu que les hommes récidivistes présentent significativement plus d’impulsivité, de recherche de sensations et de traits antisociaux que les femmes récidivistes. Ces hypothèses se confirment partiellement, alors que les hommes récidivistes (n = 39) présentent des performances inférieures à celles des hommes non-contrevenants (n = 20) et des femmes récidivistes (n = 20) sur le plan attentionnel et exécutifs. Toutefois, les femmes récidivistes ne se distinguent pas des femmes non-contrevenantes (n = 20) en matière de fonctionnement neuropsychologique. En ce qui a trait aux caractéristiques psychologiques, les résultats soutiennent partiellement les hypothèses. La discussion met en lumière que les femmes et des hommes récidivistes présentent des caractéristiques similaires, hormis en ce qui a trait au fonctionnement attentionnel et exécutif qui semble jouer un rôle dans la récidive au masculin, alors que cela n’apparaît pas être le cas chez les femmes chez qui le comportement pourrait être davantage situationnel. La nécessité que des études futures soient réalisées au moyen de devis expérimentaux, de même que les difficultés inhérentes au recrutement des femmes récidivistes sont discutées.
