Longitudinal relations among maternal behaviors, effortful control and young children's committed compliance

In a sample (n = 235) of 30-, 42-, and 54-month-olds, the relations among parenting, effortful control (EC), impulsivity, and children's committed compliance were examined. Parenting was assessed with mothers' observed sensitivity and warmth; EC was measured by mothers' and caregivers' reports, as well as a behavioral task; impulsivity was assessed by mothers' and caregivers' reports; and committed compliance was observed during a cleanup and prohibition task, as well as measured by adults' reports. Using path modeling, there was evidence that 30-month parenting predicted high EC and low impulsivity a year later when the stability of the outcomes was controlled, and there was evidence that 30- and 42-month EC, but not impulsivity, predicted higher committed compliance a year later, controlling for earlier levels of the outcomes. Moreover, 42-month EC predicted low impulsivity a year later. Fixed effects models, which are not biased by omitted time-invariant variables, also were conducted and showed that 30-month parenting still predicted EC a year later, and 42-month EC predicted later low impulsivity. Findings are discussed in terms of the importance of differentiating between effortful control and impulsivity and the potential mediating role of EC in the relations between parenting and children's committed compliance.     

D1/D5 dopamine receptors modulate spatial memory formation

We investigated the effect of the intra-CA1 administration of the D1/D5 receptor antagonist SCH23390 and the D1/D5 receptor agonist SKF38393 on spatial memory in the water maze. When given immediately, but not 3h after training, SCH23390 hindered long-term spatial memory formation without affecting non-spatial memory or the normal functionality of the hippocampus. On the contrary, post-training infusion of SKF38393 enhanced retention and facilitated the spontaneous recovery of the original spatial preference after reversal learning. Our findings demonstrate that hippocampal D1/D5 receptors play an essential role in spatial memory processing.     

Social and moral norm differences among Portuguese 1st and 6th year medical students towards their intention to comply with hand hygiene

This study examines social and moral norms towards the intention to comply with hand hygiene among Portuguese medical students from 1st and 6th years (N = 175; 121 from the 1st year, 54 from the 6th year). The study extended the theory of planned behaviour theoretical principles and hypothesised that both subjective and moral norms will be the best predictors of 1st and 6th year medical students' intention to comply with hand hygiene; however, these predictors ability to explain intention variance will change according to medical students' school year. Results indicated that the subjective norm, whose referent focuses on professors, is a relevant predictor of 1st year medical students' intention, while the subjective norm that emphasises the relevance of colleagues predicts the intentions of medical students from the 6th year. In terms of the moral norm, 6th year students' intention is better predicted by a norm that interferes with compliance; whereas intentions from 1st year students are better predicted by a norm that favours compliance. Implications of the findings highlight the importance of role models and mentors as key factors in teaching hand hygiene in medical undergraduate curricula.     

Testing the General Theory of Crime with the Circumplex Model: Curvilinear Relations between Family Functioning and Self-Control

ABSTRACT

The relation between family and low self-control is usually studied within linear hypotheses. In this study, we intended to test the familial origin of self-control under a curvilinear hypothesis. This is a cross-sectional study, with a sample of 448 adolescents and young adults. Data analysis was based on correlation and regression-based statistics. Results revealed linear associations between family functioning and juvenile deviant behavior, contrary to self-control which presented curvilinear relations with family cohesion and flexibility (i.e. both high and low extreme levels were associated with low self-control). This finding suggests a new approach to the familial origin of low self-control.     

“I’m Not the Same,but I’m Not Sorry”: Exploring Dialogical Positioning in the Self-Transformation of a Former Politically Violent Militant

This article traces the personal and cultural voices expressed in the life-story interview of a former politically violent militant regarding her engagement with and disengagement from the armed struggle. Rather than looking at the macro and meso aspects related to politically motivated violence, we examine micro-narratives which express individual arguments, sociocultural discourses, and negotiations within and between them, These are voiced in the dynamics that take place within the self-system at times of key identity transitions (e.g., from being a committed militant to becoming a former militant). In this vein, we highlight how the embodied emotional chords of personal positions, the development of meta-positions, and the positioning and repositioning movements within the dialogical self, facilitate the emergence of new and more adaptive meanings in the personal meaning system of former militants.     

Long-term memory of haptic and visual information in older adults

ABSTRACT

The present study examined haptic and visual memory capacity for familiar objects through the application of an intentional free-recall task with three-time intervals in a sample of 78 healthy older adults without cognitive impairment. A wooden box and a turntable were used for the presentation of haptic and visual stimuli, respectively. The procedure consisted of two phases, a study phase that consisted of the presentation of stimuli, and a test phase (free-recall task) performed after one hour, one day or one week. The analysis of covariance (ANCOVA) indicated that there was a main effect only for the time intervals (F (2,71) = 12.511, p = .001, η² = 0.261), with a lower recall index for the interval of one week compared to the other intervals. We concluded that the memory capacity between the systems (haptic and visual) is similar for long retrieval intervals (hours to days).
