- Análise fatorial confirmatória do Extended Class Play numa amostra portuguesa de jovens adolescentesPublication . Correia, João Carlos Verdelho; Santos, António José; Freitas, Miguel da Costa Nunes de; Rosado, António Fernando; Rubin, KennethO Extended Class Play (ECP; Burgess, Rubin, Wojslawowicz, Rose-Krasnor, & Booth, 2003) procura avaliar, através dos relatos dos pares, a reputação social dos sujeitos. O objetivo deste trabalho é testar a estrutura hexafatorial recentemente proposta, averiguando igualmente a sua adequação para género e idade, numa amostra portuguesa de 465 adolescentes (230 raparigas). Uma Análise Fatorial Confi rmatória revelou que o modelo de seis fatores apresenta bons índices de ajustamento, de fi abilidade e validade e ainda boa adequação para gênero e idade. Estes resultados são consistentes com outros trabalhos, ao sugerir que o modelo hexafatorial do ECP apresenta capacidades psicométricas aceitáveis, constituindo-se como uma medida válida a utilizar na investigação sobre a reputação e o funcionamento sociais de adolescentes.
- Assessing the quality of portuguese child care programs for toddlersPublication . Barros, Sílvia; Aguiar, CecíliaThe purpose of this study was to describe the quality of toddler child care classrooms in the district of Porto, in the north of Portugal. One hundred and sixty classrooms for children between 1 and 3 years of age participated in this study. Results suggested the existence of poor average quality and absence of good-quality classrooms. Child–adult ratio was a statistically significant predictor of overall child care quality (with lower ratios associated with higher quality). The results of this study provide information on the applicability of ITERS-R to a new cultural and linguistic context, suggesting the need to enhance the quality of Portuguese programs serving toddlers.
- Associations between attachment security and social competence in preschool childrenPublication . Veríssimo, Manuela; Santos, António José; Fernandes, Carla; Shin, Nana; Vaughn, Brian E.Attachment theorists suggest that attachment security with parents supports the quality of social adaptation in peer groups during early childhood, and numerous studies supporting this conjecture have been published. Most of these studies used enacted representations rather than mental representations of attachment security, and most studies examining mental representations used adult (parent or teacher) ratings of peer-group adaptation. Our study tested relations between preschool children’s (N = 147; age 48–69 months) mental representations of attachment by using the Attachment Story Completion Task and child-level indicators of social competence based on direct observations and sociometric interviews. General intelligence tests were administered to control for effects of developmental level on child narrative production. Analyses revealed positive, significant associations between attachment measures and all social competence composites. Children with more secure attachment representations were more socially engaged and more likely to exhibit social, emotional, and cognitive skills that contribute to peer acceptance. Results support the hypothesis that attachment security is a foundational support for peer social competence.
- Attachment representations, sleep quality and adaptative functioning in preschool age childrenPublication . Vaughn, Brian E.; El-Sheikh, Mona; Shin, Nana; Elmore-Staton, Lori; Krzysik, Lisa; Monteiro, Lígia Maria SantosBoth the attachment system and sleep are considered to be important biopsychosocial regulators of development and of adaptive functioning in children, and there is a substantial literature suggesting that the two systems may be mutually influencing. To date, however, the bulk of research attempting to link these systems has focused on infancy and the results of empirical studies are mixed. Thirty-nine preschool children participated in this study (valid sleep data for 34 cases). Attachment representations were assessed using the Attachment Story Completion Task (ASCT) and sleep was assessed using objective (i.e., actigraphy) measures. Analyses revealed that the coherence of child narratives and security scored from the ASCT were related to sleep quality indices (e.g., Sleep Activity, Wake Minutes after Sleep Onset, Sleep Efficiency). Additional analyses examined external correlates of attachment representations and tested possible interactions of attachment and sleep. No significant mediated interactions across attachment and sleep domains were found. Although the direction of effects cannot be determined, the results suggest that parent–child relationship and sleep organization are intertwined for preschool age children and the joint effects of these biopsychosocial regulators should be studied further.
- Attachment security and HPA axis reactivity to positive and challenging emotional situations in child-mother dyads in naturalistic settingsPublication . Roque, Lisa; Veríssimo, Manuela; Oliveira, Tânia Sofia Ferreira de; Oliveira, Rui FilipeThis study investigated adrenocortical activity in response to different challenging and positive affect emotional contexts in child–mother dyads, as function of attachment security (children’s secure base behaviors and mothers’ attachment representations). Fifty-one children ranging in age from 18 to 26 months and their mothers participated in this study. Secure children showed significant increases in their cortisol levels after fear episodes and significant decreases, after positive affect ones. No significant changes were found for frustration/ anger episodes. Insecure children did not show significant differences in cortisol levels in any of the episodes, which suggests that insecure attachment may be related to hypothalamic–pituitary–adrenal axis suppression in response to challenging and positive contexts. Mothers of insecure children showed significantly higher cortisol concentrations in pre- and post-session samples, than mothers of secure children. Mothers’ personal attachment representations influenced their own cortisol responses, as well as their children’s (in a marginal significant way).
- Attachment security representations in institutionalized children and children living with their families: Links to problem behaviourPublication . Torres, Nuno; Maia, Joana Branco; Veríssimo, Manuela; Fernandes, Marília; Silva, FilipaThe present work analyses differences in the attachment representations of institutionalized children as compared with children from low and high educational level living with their natural families. Participants were 91 Portuguese children, 52% girls, aged 48–96 months. There were three different groups: 19 institutionalized children, 16 low educational level families’ children and 56 from high educational level families’. Attachment representations were assessed for Security of the narratives of the Attachment Story Completion Task (ASCT). Psychopathological symptoms were assessed using the Child Behaviour Checklist for parents and caretakers. Verbal skills were assessed using the Wechsler Preschool and Primary Scale of Intelligence—Revised. Results show that institutionalized children have signifi cantly lower security of attachment representations, less verbal skills and higher aggressive behaviour than the other two groups. Attachment representations were associated with social/withdrawal and aggression, independently of age, verbal skills and parents’ education. The main effect of institutionalization on externalizing aggressive behaviour was completely mediated by the security of attachment representations.
- Challenge and threat motivation : Effects on superficial and elaborative information processingPublication . Fonseca, Ricardo Jorge Rodrigues Moita da; Blascovich, James; Garcia-Marques, TeresaThis paper integrates the motivational states of challenge and threat within a dual processing perspective. Previous research has demonstrated that individuals experience a challenge state when individuals have sufficient resources to cope with the demands of a task (Blascovich eta, 1993). Because the experience of resource availability has been shown to be associated with superficial processing (Garcia-Marques and Mackie, 2007), we tested the hypothesis that challenge is associated with superficial processing in two persuasion experiments. Experiment 1 revealed that inducing attitudes of participants in a challenge state was not sensitive to the quality of arguments presented. Experiment 2 demonstrated that the effect occurs even when task engagement, manipulated by the presence (vs. the absence) of a task observer (Blascovich et al., 1993), is high. The implications of these results for the biopsychosocial model model and the cognitive and motivational literature are discussed.
- Cognitive systems evolution: Immigrant last generations and cognitive mapping changingPublication . Figueiredo, Sandra; Martins, Margarida Alves; Silva, Carlos Fernandes daThere is little evidence on the correlation between immigration effects and the evolution of the mind and cognition, especially concerning children. Last generations of young immigrants are expected to experience adaptive strategies to respond to the school environment in order to achieve success. Specifically concerning the new language learning in the diversity of the host countries (plus the diversity of the countries of origin and home languages/cultures), it should be analyzed how the human cognitive aptitude (language aptitude and problem solving) is being reorganized in terms of thought, concepts and cultural orientations previously developed in a certain native culture. The native culture (aspects of the nationality and of the home language) is mentally associated to concepts and generates the self-regulation which implies consciousness in a home culture as a reference. How does it works for new immigrants that were separated (including cases of forced immigration) from their unique cognitive reference? Different cognitive achievements and language deficits would be constrained in their natural development and differences in academic achievement are expected. This lead to implications for the biological hypothesis of critical period concerning the new waves of immigration and ethnic differentiation in current generations. Age would be considered along with other unexpected variables such as nationality. The present study examines populations’ differences – ethnic and age – on specific language and cognitive tasks considering immigrant students in Portuguese schools (M=13 years old; SD= 2,7) with origin in different world areas: Western Europe, Eastern Europe, African countries, Latin America, Asia (Indian Asia) and China and with different home languages and cultures. Data showed a variability of groups’ achievements in cognates, text recall, lexical recall and dichotic listening tasks. Disparities among the minorities will be discussed considering educational and ethological implications. Population evolutionary characteristics might be concluded from those disparities.
- Conceções dos educadores portugueses sobre a linguagem escrita : Um estudo de casoPublication . Santos, Ana Isabel Silva; Martins, Margarida AlvesO presente artigo pretende dar conta dos resultados de uma investigação realizada junto de um grupo de 18 educadoras de infância a trabalhar na em escolas da rede pública da Ilha Terceira, Açores, Portugal, cujo objetivo foi o de compreender a sua perspetiva acerca da abordagem à linguagem escrita no âmbito da educação de infância. Foram avaliados aspetos como a posição pedagógica e metodológica que as educadoras afirmam adotar na sua intervenção pedagógica e os processos de aprendizagem que afirmam privilegiar como promotores da literacia nas suas salas. A entrevista realizada durante o segundo trimestre do ano escolar permitiu concluir que a forma de pensar destas educadoras, acerca do desenvolvimento da linguagem escrita, caracteriza-se, basicamente, pelo distanciamento relativamente a uma perspetiva emergente da literacia, centrada nas crianças, pela atribuição de uma acentuada importância às atividades e estratégias de intervenção direta e pelo défice de conhecimentos sobre a forma como se desenvolvem os processos de leitura e escrita em crianças pré-escolares.
- Correlates of self-directed behaviors in captive Cercopithecus aethiopsPublication . Daniel, João Rodrigo; Santos, António José; Vicente, Luís A.Researchers have widely used self-directed behaviors (SDB) as a behavioral indicator of anxiety in nonhuman primates. We examined if SDB rates in captive vervets (Cercopithecus aethiops) were associated with 1) proximity to conspecifics in general, 2) relative dominance rank of proximity partners, and 3) postconflict situations. Subjects were members of a captive group of vervets at the Lisbon Zoo, Portugal. The group comprised 3 males and 7 females, which were focal sampled for 10.5 h each. Vervets did not engage in more SBD while in proximity of conspecifics than while alone, and individual SDB rates were not generally influenced by dominance ranks of neighbors. Yet, victims of conflicts significantly increased their SDB rates after agonistic episodes, which is consistent with the view that SDB rates are an index of anxiety in Cercopithecus aethiops.
