Exploring the evolutionary origins of overimitation: a comparison across domesticated and non‐domesticated canids

When learning from others, human children tend to faithfully copy – or ‘overimitate’ – the actions of a demonstrator, even when these actions are irrelevant for solving the task at hand. We investigate whether domesticated dogs (Canis familiaris) and dingoes (Canis dingo) share this tendency to overimitate in three experiments. In Experiment 1, dogs and dingoes had the opportunity to solve a puzzle after watching an ostensive demonstrator who used both a relevant action and an irrelevant action. We find clear evidence against overimitation in both species. In contrast to human children (Horner & Whiten, 2005), dogs and dingoes used the irrelevant action less often across trials, suggesting that both species were filtering out the irrelevant action as they gained experience with the puzzle (like chimpanzees; Horner & Whiten, 2005). Experiments 2 and 3 provide further evidence against overimitation, demonstrating that both species’ behavior is better characterized by individual exploration than overimitation. Given that both species, particularly dogs, show human‐like social learning in other contexts, these findings provide additional evidence that overimitation may be a unique aspect of human social learning.

Mindfulness and psychological distress in men during the COVID-19 pandemic: The mediating role of environmental mastery and purpose in life

Men's mental health has been severely affected during the COVID-19 pandemic, with many studies focussing on the determinants of men's psychological distress. This study aimed at examining the relationships between mindfulness, environmental mastery (EM), purpose in life (PL) and indicators of psychological distress (i.e., common mental disorders and perceived stress). This was a cross-sectional online study in which participants were 1,006 men aged between 29 and 39 years (45.1%), residing in Brazil during the first wave of the COVID-19 pandemic. A parallel multiple mediator model was used to test the study variables' relationships, using mindfulness as the independent variable and indicators of psychological distress as the dependent variables. Results indicated that EM and PL significantly mediated the effects of mindfulness on men's psychological distress, lowering its levels and accounting for 31% of common mental disorders and 51% of perceived stress. Implications for public health policies and clinical practice are discussed.     

Career Counseling and Vocational Psychology in Portugal: A Political Perspective

In this article, we present an overview of the political context of vocational psychology and career counseling in Portugal. The essence of our position is that career counseling needs to encompass all the major tasks of personal and social development, beyond the traditional focus on primarily vocational/occupational goals. Given the importance of social and political factors that are apparent in an analysis of the Portuguese climate within career development, we propose that vocational psychology must go beyond a conceptualization of vocational behavior and intervention based on a person–environment fit model and must try to enhance strategies for the development of persons in a broader sense. We further propose that we need to provide career counseling not only at critical decision points, but throughout the life-span, and should not focus merely on occupational details, but on all matters of the development of the person as a whole. Finally, we suggest a perspective on career counseling and vocational psychology that is more responsive to our cultural and historical context and which is sensitive to the reality of a new political era in Portugal.     

Role of Stressful Life Events in Homelessness: An Intragroup Analysis

The present paper describes the results of an analysis of individual differences—using multidimensional strategies—in stressful life event data collected from a representative sample of homeless people (N = 289) in Madrid, Spain, which revealed the existence of three subgroups within the sample. Each subgroup can be defined by the following differentiating characteristics: The first cluster (n = 124) was characterized by economic problems; the second (n = 80) by health problems, alcohol abuse, and death of one or both parents; and the third cluster (n = 50) by an accumulation of stressful life in childhood events and alcohol abuse. In order to define the subgroups, the article also examines the differences found in other variables such as total duration of homelessness, mental and physical health status, and social support availability, among others. The existence of such subgroups within the homeless population emphasizes the importance of designing different interventions for each of these groups, adapted to their diverse needs.     

Computerized stroop test to assess selective attention in children with attention deficit hyperactivity disorder

Research shows abnormal function of the pre-frontal cortex in Attention Deficit Hyperactivity Disorder (ADHD). This cortex is involved in the control of executive functions related to planning and execution of goal-oriented strategies, working memory, inhibitions, cognitive flexibility, and selective attention. Selective attention involves focus on the target stimulus, ignoring competing distractions. The Stroop Test (Stroop, 1935) is usually used to evaluate selective attention. This study investigated whether children with ADHD could exhibit modified performance in the Stroop Test. Using a computerized version of this test (Capovilla, Montiel, Macedo, & Charin, 2005), the study compared the reaction times (RTs) of 62 Brazilian children, between 8 and 12 years of age, 31 of whom were diagnosed with ADHD and sent to psychiatric clinics, and 31 without ADHD studying in regular schools. All children with ADHD satisfied the criteria of the DSM-IV-TR and were evaluated with the Conners Abbreviated Questionnaire (Goyette, Conners, & Ulrich, 1978), completed by parents and teachers. The results revealed that children with ADHD exhibit greater interference in RT than children without ADHD. This corroborated the hypothesis that children with ADHD exhibit a deficit in selective attention, consisting in augmented RTs, as measured by the Computerized Stroop Test.     

Family perceptions and coping strategies in cases of intersexuality: understanding their significance

Considering that the intersexual condition has a negative impact on the individual, their family, and society, health professionals and researchers have dedicated themselves to is to describe and understand the perceptions of primary caregivers regarding intersexuality and its developmental aspects. Six mothers and one grandmother of school age children were interviewed. The data indicated that living with the stigma of intersexuality can mean a permanent state of crisis within the family system. Issues such as guilt about the child's suffering and questions related to the choice of gender follow the family from the moment of diagnosis. It is suggested that the therapeutic follow-up should foster the necessary conditions for the family group to be organized as a model of competence, replacing the model of guilt.
