The effects of parental sensitivity and involvement in caregiving on mother–infant and father–infant attachment in a portuguese sample

In the present longitudinal study, we investigated attachment quality in Portuguese mother–infant and in father–infant dyads, and evaluated whether attachment quality was related to parental sensitivity during parent–infant social interaction or to the amount of time each parent spent with the infant during play and in routine caregiving activities (e.g., feeding, bathing, play). The sample consisted of 82 healthy full-term infants (30 girls, 53 boys, 48 first born), and their mothers and fathers from mostly middle-class households. To assess parental sensitivity, mothers and fathers were independently observed during free play interactions with their infants when infants were 9 and 15 months old. The videotaped interactions were scored by masked coders using the Crittenden’s CARE-Index. When infants were 12 and 18 months old, mother–infant and father–infant dyads were videotaped during an adaptation of Ainsworth’s Strange Situation. Parents also described their level of involvement in infant caregiving activities using a Portuguese version of the McBride and Mills Parent Responsibility Scale. Mothers were rated as being more sensitive than fathers during parent–infant free play at both 9 and 15 months. There also was a higher prevalence of secure attachment in mother–infant versus father–infant dyads at both 12 and 18 months. Attachment security was predicted by the amount of time mothers and fathers were involved in caregiving and play with the infant, and with parents’ behavior during parent–infant free play.

Les relations d’attachement et d’activation père-enfant : effet modérateur de l’engagement paternel pour prédire le développement socio-affectif des enfants

Tout autant que la mère, le père est une figure d’attachement importante pour l’enfant. Toutefois le lien d’attachement père-enfant se formerait différemment du lien d’attachement mère-enfant. Les pères sont souvent plus engagés que les mères dans des activités ludiques, moins dans des activités de soins. Les jeux faits avec le père sont souvent plus physiques aussi, plus stimulants. En incitant son enfant au jeu de façon sensible, le père devient un tremplin pour l’exploration de son enfant et le développement de sa confiance en soi et en l’autre. C’est en tant que figure d’ouverture sur le monde que le père aurait une plus grande influence sur le développement de son enfant. C’est ce que nous apprennent les études sur l’engagement paternel. Jusqu’à maintenant peu d’auteurs ont étudié l’engagement des pères en même temps que l’attachement père-enfant, mais plusieurs proposent déjà que cette fonction d’ouverture sur le monde expliquerait la formation du lien père-enfant. La relation d’attachement père-enfant serait basée sur une relation d’activation. L’objectif de la présente thèse est précisément de mieux comprendre la nature du lien d’attachement père-enfant. Deux articles composent cette thèse. Le premier article est théorique et fait une recension de la littérature sur l’attachement père-enfant et l’engagement paternel. Le deuxième article est empirique et propose justement de vérifier l’influence de l’engagement paternel sur la formation du lien d’attachement au père. En tout 53 dyades pères-enfants ont participé à cette étude. L’engagement des pères au niveau du réconfort, de la stimulation et de la discipline a été évalué lorsque les enfants avaient entre 12 et 18 mois. À cet âge, la qualité d’attachement et de la relation d’activation ont aussi été évaluées, respectivement avec la Situation étrangère et la Situation risquée. Les deux mises en situation ont ensuite été comparées pour voir laquelle prédit mieux le développement des enfants à l’âge préscolaire, au niveau des compétences sociales, des problèmes intériorisés et des problèmes extériorisés. Les résultats obtenus indiquent que la Situation risquée prédit mieux le développement socio-affectif des enfants (compétences sociales et problèmes intériorisés). Aucun lien n’a été trouvé avec la Situation étrangère, même en tenant compte de l’engagement du père au niveau du réconfort. Ces résultats valident la théorie de la relation d’activation et l’importance de la fonction paternelle d’ouverture sur le monde. Les limites de la présente étude, ainsi que ses implications théoriques et méthodologiques, seront abordées dans la discussion du deuxième article et en conclusion de la présente thèse.

Le lien entre le stress parental du père et le développement de la relation d’activation chez les enfants âgés entre 12 et 18 mois

De nos jours, le père est de plus en plus présent dans le quotidien de son enfant. Par son implication et son engagement, le père dans le développement de l’enfant a un rôle important et unique. Sa contribution se ferait entre autre par rapport à l’ouverture au monde en encourageant l’enfant à prendre des risques. Comme être mère, être père c’est de faire face à un ensemble de situations nouvelles quotidiennes, de vivre des déséquilibres et de l’imprévisibilité et de ne pas toujours être en contrôle des évènements qui se produisent. Ainsi, exercer ce rôle peut entraîner un certain niveau de stress qui peut influencer le développement de l’enfant. La présente étude vise à examiner l’existence d’un lien entre le stress parental du père et la relation d’activation chez les enfants âgés entre 12 et 18 mois ainsi que l’attachement père-enfant. Des données ont été recueillies auprès de 58 pères et leur enfant âgé entre 12 et 18 mois. Les résultats montrent que le stress parental n’est pas significativement lié à la relation d’activation ni à l’attachement père-enfant. De plus, le sexe de l’enfant ne modère pas ce lien. On note que le sexe de l’enfant est corrélé à la relation d’activation, c’est-à-dire que les garçons sont plus activés positivement que les filles.

The role played by the interaction between genetic factors and attachment in the stress response in infancy

Background: The importance of understanding which environmental and biological factors are involved in determining individual differences in physiological response to stress is widely recognized, given the impact that stress has on physical and mental health. Methods: The child-mother attachment relationship and some genetic polymorphisms (5-HTTLPR, COMT and GABRA6) were tested as predictors of salivary cortisol and alpha amylase concentrations, two biomarkers of hypothalamic-pituitary-adrenocortical (HPA) axis and sympathetic adrenomedullary (SAM) system activity, during the Strange Situation (SS) procedure in a sample of more than 100 healthy infants, aged 12 to 18 months. Results: Individual differences in alpha amylase response to separation were predicted by security of attachment in interaction with 5-HTTLPR and GABRA6 genetic polymorphisms, whereas alpha amylase basal levels were predicted by COMT x attachment interaction. No significant effect of attachment, genetics and their interaction on cortisol activity emerged. Conclusions: These results help to disentangle the role played by both genetic and environmental factors in determining individual differences in stress response in infancy. The results also shed light on the suggestion that HPA and SAM systems are likely to have different characteristic responses to stress.

The significance of insecure attachment and disorganization in the development of children's externalizing behavior: A meta-analytic study

This study addresses the extent to which insecure and disorganized attachments increase risk for externalizing problems using meta-analysis. From 69 samples (N = 5,947), the association between insecurity and externalizing problems was significant, d = 0.31 (95% CI: 0.23, 0.40). Larger effects were found for boys (d = 0.35), clinical samples (d = 0.49), and from observation-based outcome assessments (d = 0.58). Larger effects were found for attachment assessments other than the Strange Situation. Overall, disorganized children appeared at elevated risk (d = 0.34, 95% CI: 0.18, 0.50), with weaker effects for avoidance (d = 0.12, 95% CI: 0.03, 0.21) and resistance (d = 0.11, 95% CI: −0.04, 0.26). The results are discussed in terms of the potential significance of attachment for mental health.

Apego: evolução da relação e discriminação do objeto

A presente investigação constitui um estudo específico de parte dos achados da pesquisa "Influência das Condições de Atendimento das Creches no Desenvolvimento Cognitivo e Emocional das Crianças" (Almeida, L.S. de; Colinvaux, D.; Pardal, M.V.; e Penna, M.M.S., 1985). 'Teve como hipótese geral a existência de uma relação entre o desenvolvimento da noção de objeto e a evolução do comportamento de apego dirigido à figura principal de cuidados em crianças de creche. Fundamentou-se, teoricamente, nas postulações de J. Piaget sobre o desenvolvimento cognitivo e mais especificamente ainda sobre o conceito de objeto e de J. Bowlby sobre o comportamento de apego. O estudo foi conduzido em uma amostra de 39 crianças, na faixa etária de 6 a 24 meses, que frequentavam creche externato em regime integral. Todas as crianças foram testadas na serie "busca do objeto desaparecido" da escala "As Etapas da Inteligência Sensório-Motora da Criança de Zero a Dois Anos" (I.Casati & I. Lezine, 1968) e participaram de uma situação experimental adaptada da "situação do estranho" (M. Ainsworth & B. Wittig, 1969). Não foi estabeleci da uma relação significativa entre as variáveis em estudo. Contudo, os dados coletados evidenciaram uma tendência para essa correlação. A autora sugere, portanto, que outras investigações acerca dessas variáveis sejam conduzidas em amostras com um número significativamente maior de crianças. Propõe, ainda, que a variável noção de permanência de pessoa também seja considerada em futuras pesquisas nessa área.

Studio longitudinale sulle capacità cognitive del cane: discriminazione di quantità ed apprendimento per imitazione in relazione all'attaccamento

Il presente studio ha indagato e valutato alcune abilità cognitive del cane: la capacità di discriminare quantità e le capacità di apprendimento mediante imitazione; quest’ultima è poi stata messa in relazione con l’attaccamento nei confronti del proprietario. Per l’esecuzione della prima indagine sono stati messi appunto due test: il primo si è basato esclusivamente sulla presentazione di uno stimolo visivo: diversi quantitativi di cibo, differenti tra loro del 50%, sono stati presentati al cane; la scelta effettuata dai soggetti testati è stata premiata con differenti tipi di rinforzo differenziale o non differenziale. Il secondo test è stato diviso in due parti: sono stati presentati al cane diversi quantitativi di cibo sempre differenti tra loro del 50% ma nella prima parte del test l’input sensoriale per il cane è stato esclusivamente uditivo mentre nella seconda parte è stato sia uditivo che visivo. Ove è stato possibile è stato applicato ai cani un cardiofrequenzimetro al fine di eseguire una valutazione delle variazioni della frequenza cardiaca nel corso del test. Lo scopo è stato quello di valutare se i soggetti testati erano in grado di discriminare la quantità maggiore. La seconda indagine ha analizzato le capacità di apprendimento di 36 soggetti che sono stati suddivisi in cani da lavoro e pet. I soggetti protagonisti dello studio hanno eseguito il Mirror Test per la valutazione dell’apprendimento per imitazione. I soggetti presi in considerazione, sono stati sottoposti a scansione termografica all’inizio ed al termine del test ed è stata rilevata la loro frequenza respiratoria nella fase iniziale e finale del test. In 11 soggetti che hanno eseguito il precedente test è stato possibile eseguire anche il Strange Situation Test per la valutazione dell’attaccamento al proprietario; i test in questione sono stati videoregistrati ed analizzati per mezzo di un software preposto (OBSERVER XT 10).

The effect of gender context on children's social behaviour in a limited resources situation : an observational study

Knowing when to compete and when to cooperate to maximize opportunities for equal access to activities and materials in groups is critical to children's social and cognitive development. The present study examined the individual (gender, social competence) and contextual factors (gender context) that may determine why some children are more successful than others. One hundred and fifty-six children (M age=6.5 years) were divided into 39 groups of four and videotaped while engaged in a task that required them to cooperate in order to view cartoons. Children within all groups were unfamiliar to one another. Groups varied in gender composition (all girls, all boys, or mixed-sex) and social competence (high vs. low). Group composition by gender interaction effects were found. Girls were most successful at gaining viewing time in same-sex groups, and least successful in mixed-sex groups. Conversely, boys were least successful in same-sex groups and most successful in mixed-sex groups. Similar results were also found at the group level of analysis; however, the way in which the resources were distributed differed as a function of group type. Same-sex girl groups were inequitable but efficient whereas same-sex boy groups were more equitable than mixed groups but inefficient compared to same-sex girl groups. Social competence did not influence children's behavior. The findings from the present study highlight the effect of gender context on cooperation and competition and the relevance of adopting an unfamiliar peer paradigm when investigating children's social behavior.

Survival Power: An Empirical Analysis of Power in a Life and Death Situation

This paper seeks to identify what antecedents of power make it more or less likely for people to survive in a life-threatening situation.In particular, we look at the Titanic disaster as the life or death situation. Maritime disasters can be interpreted as quasi-natural experiments because every person is affected by the shock. True human nature becomes apparent in such a dangerous situation. Five antecedents of power are distinguished: physical strength, economic resources, nationality, social and moral factors. This empirical analysis supports the notion that power is a key determinant in extreme situations of life or death.

Fiji pre-service primary teachers' understanding of physical science : a cultural perspective

Science and technology are promoted as major contributors to national development. Consequently, improved science education has been placed high on the agenda of tasks to be tackled in many developing countries, although progress has often been limited. In fact there have been claims that the enormous investment in teaching science in developing countries has basically failed, with many reports of how efforts to teach science in developing countries often result in rote learning of strange concepts, mere copying of factual information, and a general lack of understanding on the part of local students. These generalisations can be applied to science education in Fiji. Muralidhar (1989) has described a situation in which upper primary and middle school students in Fiji were given little opportunity to engage in practical work; an extremely didactic form of teacher exposition was the predominant method of instruction during science lessons. He concluded that amongst other things, teachers' limited understanding, particularly of aspects of physical science, resulted in their rigid adherence to the text book or the omission of certain activities or topics. Although many of the problems associated with science education in developing countries have been documented, few attempts have been made to understand how non-Western students might better learn science. This study addresses the issue of Fiji pre-service primary teachers' understanding of a key aspect of physical science, namely, matter and how it changes, and their responses to learning experiences based on a constructivist epistemology. Initial interviews were used to probe pre-service primary teachers' understanding of this domain of science. The data were analysed to identify students' alternative and scientific conceptions. These conceptions were then used to construct Concept Profile Inventories (CPI) which allowed for qualitative comparison of the concepts of the two ethnic groups who took part in the study. This phase of the study also provided some insight into the interaction of scientific information and traditional beliefs in non-Western societies. A quantitative comparison of the groups' conceptions was conducted using a Science Concept Survey instrument developed from the CPis. These data provided considerable insight into the aspects of matter where the pre-service teachers' understanding was particularly weak. On the basis of these preliminary findings, a six-week teaching program aimed at improving the students' understanding of matter was implemented in an experimental design with a group of students. The intervention involved elements of pedagogy such as the use of analogies and concept maps which were novel to most of those who took part. At the conclusion of the teaching programme, the learning outcomes of the experimental group were compared with those of a control group taught in a more traditional manner. These outcomes were assessed quantitatively by means of pre- and post-tests and a delayed post-test, and qualitatively using an interview protocol. The students' views on the various teaching strategies used with the experimental group were also sought. The findings indicate that in the domain of matter little variation exists in the alternative conceptions held by Fijian and Indian students suggesting that cultural influences may be minimal in their construction. Furthermore, the teaching strategies implemented with the experimental group of students, although largely derived from Western research, showed considerable promise in the context of Fiji, where they appeared to be effective in improving the understanding of students from different cultural backgrounds. These outcomes may be of significance to those involved in teacher education and curriculum development in other developing countries.

Noblesse oblige? Determinants of survival in a life and death situation

This paper explores what determines the survival of people in a life–and-death situation. The sinking of the Titanic allows us to inquire whether pro-social behavior matters in such extreme situations. This event can be considered a quasi-natural experiment. The empirical results suggest that social norms such as ‘women and children first’ are persevered during such an event. Women of reproductive age and crew members had a higher probability of survival. Passenger class, fitness, group size, and cultural background also mattered.

Situation Review of Barley Yellow Dwarf Virus in West Asia and North Africa

Symptoms of barley yellow dwarf (BYD) have been observed on cereals in nearly all countries of West Asia and North Africa. Its incidence. however, has varied during the last 15 years. Observations from field surveys are summarized. Since symptoms of barley yellow dwarf virus (BYDV) are of low diagnostic value, especially in wheat (Triticum aestivum L.), more precise qualitative and quantitative detection was derived by vector transmission and serology. In 1985 and 1986. preliminary surveys by enzyme-linked immunosorbent assay (ELlS A) indicated that BYDV incidence in the regions surveyed in Syria, Morocco, and Tunisia was around 7. 22. and 24%. respectively. By vector transmission PAV-, RPV-, and RMV-like isolates ofBYDV were identified in Morocco and the PAV-like isolate in Syria. By serology PAV-like isolates were identified in Ethiopia, Lebanon. Morocco. Syria. and Tunisia. and MA V-like isolates were identified from Morocco and Tunisia. The PAV-like type was the most common in all countries surveyed. Screening for BYDV resistance by natural infection has been carried out in a number of countries of the region during the last few years. Screening for resistance by aphid inoculation was initiated in Syria in 1986 at the International Center for Agricultural Research in the Dry Areas (ICARDA). Such screening is expected to follow in other countries of the region soon.

Training clinical psychologists : The current situation and a way forward [Guest Editorial]

In the past, training in clinical psychology in Australia and overseas has been dominated by definitions of input— hours of classes or supervision and of specific components. While prospective practitioners have been required to demonstrate the acquisition of generic competencies, satisfaction of these input driven criteria has been required for both accreditation and registration. Ironically, for a discipline that prides itself on requiring empirical bases for practice and communicating those to students (Calhoun, Moras, Pilkonis, & Rehm, 1998), training criteria have been primarily derived from accepted wisdom, rather than from a sound body of data. The situation has been remarkably like that of a treatment establishing standards of fidelity before its effective components are known—an action our profession has correctly criticised in the past (Herbert & Mueser, 1992).
