“…For anger, mean emotional response was 2.86 (SD = 3.21), and for sadness it was .73 (SD = 1.94). Anger and sadness responses have been so defined in our past work including our most recent study (Lewis & Ramsay, 2005).…”

“…If sadness reflects the absence of control, sadness should be related to increases in cortisol response. We examined this possibility using two goal blockage situations with young infants (Lewis & Ramsay, 2005). For both blockages sadness was, while anger was not, related to cortisol response; infants showing greater sadness showed a higher cortisol response.…”

“…Consistent with Henry's view, we expected anger to be associated with increased heart rate, but not cortisol and sadness to be associated with increased cortisol, but not heart rate. Four months was chosen as the sample age since in past work it has proved a good time to examine individual differences in infant anger and sadness responses to goal blockage Lewis & Ramsay, 2005;Sullivan & Lewis, 2003).…”

This study examined the relation of anger and sadness to heart rate and cortisol in 4-month-old infants' (N = 56) response to a goal blockage. The blockage occurred during a contingency learning procedure where infants' response no longer produced a learned interesting event. Anger and sadness were the major emotional expressions to the blockage. The two emotional expressions were differentially related to heart rate and cortisol. Anger was related to increased heart rate, but not cortisol, whereas sadness was related to increased cortisol, but not heart rate. Along with other work, the present results support the view that infant anger in response to goal blockage involves autonomic as opposed to adrenocortical activation as a consequence of an expectation of control over the event.In contrast, sadness in response to goal blockage involves adrenocortical as opposed to autonomic activation stemming from the absence of an expectation of control.From the first months of life, individual differences have been found in infant response to the blockage of a desired goal

“…Para além das alterações comportamentais também podemos verificar que, do ponto fisiológico, a condição Still-Face funciona como um stressor de moderado impacto. Na verdade, durante esta trapaça experimental o ritmo cardíaco dos bebés aumenta, a actividade do tónus vagal decai (Haley & Stansbury;Moore & Calkins, 2004), e os níveis de libertação de cortisona aumentam (Haley & Stansbury, 2003;Ramsay & Lewis, 2003;Lewis & Ramsay, 2005). Estes resultados demonstram que embora o Still-Face não seja previsivelmente uma situação traumática com efeitos permanentes, localmente afecta a regulação emocional.…”

No quadro dos estudos sobre o relacionamento mãe-filho, procurámos averiguar a relação entre a reactividade infantil observada em condições de stress e a qualidade do comportamento interactivo infantil e materno em jogo livre. Para o efeito, seleccionámos uma amostra de 40 díades mãe-filho cujos bebés tinham cerca de 3 meses e não apresentavam nenhuma condição declarada de risco. A qualidade da interacção mãe-filho foi avaliada em jogo livre através da escala CARE-Index. Para testar a reactividade infantil submetemos os bebés à situação experimental Still-Face. Os resultados mostram que a reactividade infantil expressa naquela situação laboratorial não é independente do comportamento dos bebés em jogo livre. Com efeito, os bebés com maior dificuldade em conformar-se com a ausência de resposta materna apresentam um comportamento menos cooperativo e difícil em jogo livre. Em sentido inverso, os bebés que em jogo livre são menos participativos apresentam menores índices de reactividade negativa quando a mãe mantém a cara inexpressiva. Em termos diádicos, verificamos que existe uma forte correlação entre o comportamento cooperativo do bebé e a sensibilidade materna em jogo livre. Os resultados são discutidos no quadro do desenvolvimento dos processos de interacção mãe e filho.

“…However, these two types of reactions to stress are not always correlated in adults [20]; in other words, researchers measuring both reactions to stressors, do not always find straightforward relations between both. In infants, behavior and cortisol reactions are often modestly correlated, but not always, and not always in the same direction [9,11,13,14]. Because both types of reactions constitute different aspects of the stress reaction, and because both are related to an individual's health and adaptation, it is important to study the effects of stressors on both types of reactions.…”
