Structural Validity of the Wechsler Intelligence Scale for Children (WISC-IV) in a French-speaking Swiss sample

The Wechsler Intelligence Scale for Children-fourth edition (i.e. WISC-IV) recognizes a four-factor scoring structure in addition to the Full Scale IQ (FSIQ) score: Verbal Comprehension (VCI), Perceptual Reasoning (PRI), Working Memory (WMI), and Processing Speed (PSI) indices. However, several authors suggested that models based on the Cattell-Horn-Carroll (CHC) theory with 5 or 6 factors provided a better fit to the data than does the current four-factor solution. By comparing the current four-factor structure to CHC-based models, this research aimed to investigate the factorial structure and the constructs underlying the WISC-IV subtest scores with French-speaking Swiss children (N = 249). To deal with this goal, confirmatory factor analyses (CFAs) were conducted. Results showed that a CHC-based model with five factors better fitted the French-Swiss data than did the current WISC-IV scoring structure. All together, these results support the hypothesis of the appropriateness of the CHC model with French-speaking children.

Safety-seeking behaviours and verbal auditory hallucinations in schizophrenia.

Verbal auditory hallucinations can have a strong impact on the social and professional functioning of individuals diagnosed with schizophrenia. The safety-seeking behaviours used to reduce the threat associated with voices play a significant role in explaining the functional consequences of auditory hallucinations. Nevertheless, these safety-seeking behaviours have been little studied. Twenty-eight patients with schizophrenia and verbal auditory hallucinations were recruited for this study. Hallucinations were evaluated using the Psychotic Symptom Rating Scale and the Belief About Voice Questionnaire and safety behaviours using a modified version of the Safety Behaviour Questionnaire. Our results show that the vast majority of patients relies on safety behaviours to reduce the threat associated with voices. This reliance on safety behaviours is mostly explained by beliefs about origin of voices the omnipotence attributed to hallucinations and the behavioural and emotional reactions to the voices. Safety-seeking behaviours play an important role in maintaining dysfunctional beliefs with respect to voices. They should be better targeted within the cognitive and behavioural therapies for auditory hallucinations.

Evolución diacrónica del sistema verbal de movimiento en español: entrar y salir (ss. XII-XV)

Esta investigación es una tesis doctoral que tiene como objetivo el estudio de la evolución semántica de los verbos entrar y salir desde el punto de vista diacrónico en español medieval mediante la aplicación de las herramientas teóricas proporcionadas por la Lingüística cognitiva. A través de un corpus de documentaciones extraídas del Corpus del nuevo diccionario histórico del español de la Real Academia Española y que abarcan el intervalo desde el siglo XIII al XV, se analizan los valores semánticos de ambos verbos con la finalidad de determinar cómo fue desarrollándose su uso, qué significados generaron otros nuevos y cómo se relacionan entre sí los significados de un mismo verbo. Para llevar a cabo esta tarea se ha partido de la Teoría de los prototipos aplicada a la categorización léxica, así como de la Teoría de la metáfora y la metonimia. Asimismo, se ha analizado la estructura sintáctica de cada ejemplo, la selección léxica de los argumentos verbales y la tradición discursiva a la que pertenece cada documentación. De esta forma, es posible, no sólo describir la evolución semántica de ambos verbos, sino completar la información sobre las causas de su desarrollo diacrónico. Finalmente, se establecen las relaciones semánticas de carácter diacrónico existentes entre ambos verbos en tanto que miembros de un mismo grupo léxico, los verbos de movimiento, y se corrobora su vinculación más allá de una relación de antonimia de tipo primario.

Attention, memory and verbal learning and their relation to schizotypal traits in unaffected parents of schizophrenic patients

The main objective of this ex post facto study is to compare the differencesin cognitive functions and their relation to schizotypal personality traits between agroup of unaffected parents of schizophrenic patients and a control group. A total of 52unaffected biological parents of schizophrenic patients and 52 unaffected parents ofunaffected subjects were assessed in measures of attention (Continuous PerformanceTest- Identical Pairs Version, CPT-IP), memory and verbal learning (California VerbalLearning Test, CVLT) as well as schizotypal personality traits (Oxford-Liverpool Inventoryof Feelings and Experiences, O-LIFE). The parents of the patients with schizophreniadiffer from the parents of the control group in omission errors on the ContinuousPerformance Test- Identical Pairs, on a measure of recall and on two contrast measuresof the California Verbal Learning Test. The associations between neuropsychologicalvariables and schizotpyal traits are of a low magnitude. There is no defined pattern ofthe relationship between cognitive measures and schizotypal traits

Diagnosing Patients Combining Principal Components Analysis and Case Based Reasoning

This paper addresses the application of a PCA analysis on categorical data prior to diagnose a patients data set using a Case-Based Reasoning (CBR) system. The particularity is that the standard PCA techniques are designed to deal with numerical attributes, but our medical data set contains many categorical data and alternative methods as RS-PCA are required. Thus, we propose to hybridize RS-PCA (Regular Simplex PCA) and a simple CBR. Results show how the hybrid system produces similar results when diagnosing a medical data set, that the ones obtained when using the original attributes. These results are quite promising since they allow to diagnose with less computation effort and memory storage

Influências do comportamento comunicativo não-verbal do docente em sala de aula: visão dos docentes de enfermagem

Na interação professor-aluno, o professor tem um importante papel e seu bom desempenho depende da consciência e habilidade que tenha na comunicação. Este trabalho teve como objetivo verificar junto aos docentes de Enfermagem, o conhecimento e a importância atribuída aos sinais não-verbais na sua interação em sala de aula. É um estudo exploratório, na linha qualitativa e foram entrevistados 25 docentes da EEUSP, de outubro a dezembro de 1999. Dentre os achados, pudemos verificar que são considerados facilitadores da interação: algumas características do professor, características do aluno, a regularidade de contato, o tipo de conteúdo exposto e a própria comunicação.

Specific vs general cognitive remediation for executive functioning in schizophrenia: A multicenter randomized trial.

BACKGROUND: This study assesses the benefits of an individualized therapy (RECOS program) compared with the more general cognitive remediation therapy (CRT). METHODS: 138 participants took part with 65 randomized to CRT and 73 to RECOS. In the RECOS group, participants were directed towards one of five training modules (verbal memory, visuo-spatial memory and attention, working memory, selective attention or reasoning) corresponding to their key cognitive concern whereas the CRT group received a standard program. The main outcome was the total score on BADS (Behavioural Assessment of Dysexecutive Syndrome) and the secondary outcomes were: cognition (executive functions; selective attention; visuospatial memory and attention; verbal memory; working memory) and clinical measures (symptoms; insight; neurocognitive complaints; self-esteem). All outcomes were assessed at baseline (T1), week 12 (posttherapy, T2), and follow-up (week 36, i.e., 6months posttherapy, T3). RESULTS: No difference was shown for the main outcome. A significant improvement was found for BADS' profile score for RECOS at T2 and T3, and for CRT at T3. Change in BADS in the RECOS and CRT arms were not significantly different between T1 and T2 (+0.86, p=0.108), or between T1 and T3 (+0.36, p=0.540). Significant improvements were found in several secondary outcomes including cognition (executive functions, selective attention, verbal memory, and visuospatial abilities) and clinician measures (symptoms and awareness to be hampered by cognitive deficits in everyday) in both treatment arms following treatment. Self-esteem improved only in RECOS arm at T3, and working memory improved only in CRT arm at T2 and T3, but there were no differences in changes between arms. CONCLUSIONS: RECOS (specific remediation) and CRT (general remediation) globally showed similar efficacy in the present trial.

A auto-estima e o não-verbal dos pacientes com queimaduras

Esta pesquisa teve como objetivos identificar o grau de auto-estima dos pacientes do Ambulatório de Seqüelas de Queimaduras do HC-FMUSP e identificar os sinais não-verbais emitidos pelos pacientes, quando questionados sobre sua auto-estima. Realizado com 80 pacientes (54 mulheres e 26 homens) atendidos na unidade durante o mês de fevereiro de 2002, o projeto foi aprovado pelas Comissões de Ética em Pesquisa da EEUSP e do HC-FMUSP e as entrevistas individuais com os pacientes baseadas em uma escala para avaliação de auto-estima validada no Brasil e na classificação de sinais não-verbais proposta por Silva. Dentre os resultados, verificamos que 18,75% pacientes apresentam baixa auto-estima, 32,50% média auto-estima e 48,75% pacientes alta auto-estima. O complemento foi a função dos sinais não-verbais mais freqüente entre os pacientes.
