Background: The dominant view based on the deficit model of developmental psychopathology is that early adverse rearing impairs cognition. In contrast, an emerging evolutionary-developmental model argues that individuals exposed to early-life stress may have improved cognitive abilities that are adapted to harsh environments. We set out to test this hypothesis by examining cognitive functions in parentally deprived children in Nigeria. Methods: Cognitive performance was compared between 53 deprived children who currently live in institutional homes and foster families and 51 nondeprived control participants. We used a multifaceted neurocognitive test battery for the assessment of inhibition, set-shifting and working memory. Results: Results showed that the deprived and nondeprived group did not significantly differ in their performance on set-shifting and inhibition tasks. Conversely, the deprived group performed significantly better than the nondeprived group in the working memory task. Discussion: We interpret the enhanced working memory ability of the deprived group as a correlate of its ecological relevance. In Nigeria, underprivileged children may need to rely to a larger extent on working memory abilities to attain success through academic work. This study provides further evidence that exposure to early adversity does not necessarily impair cognitive functions but can even enhance it under some conditions and in some domains.

Background As a global phenomenon, suicide has generated a lot of concern. Scholars from various fields have conducted extensive research on the prevalence, causes, factors, and/or management or possible solutions to suicidal ideation. Despite the research efforts, suicidal cases worldwide still yell for more empirical attention. No doubt that some of the extant literature have specifically evidenced the causal links and factors in suicidal ideation. Yet, none had focused on the moderating roles of coping and resilience in an academic population. We therefore, examined the moderating roles of coping and resilience in the relationship between academic stress and suicidal ideation. Method We used a cross-sectional design to sample 505 participants (329 males and 176 females) from three southern Nigerian universities. Participants who willingly indicated their participatory consent were administered a paper self-report questionnaire containing the Lakaev Academic Stress Response Scale (LASRS), Scale for Suicidal Ideation (SSI), Brief COPE (B-COPE), and Resilience Scale (RS-14). Hierarchical regression analysis was used to test the hypotheses of the study. Academic stress (r = 0.17; p.001) was found to be positively associated with suicidal ideation, whereas resilience (r = −.22; p.001) was found to be negatively associated with suicidal ideation. Suicidal ideation had no significant correlation with adaptive coping style, but it did have a significant correlation with maladaptive coping (r = .15; p.001). The regression-based PROCESS macro showed that academic stress was a significant predictor of coping [ΔR2 = .03, F (1, 502) = 16.18, p = .01]. Academic stress was positively associated with suicidal ideation at low or moderate levels of adaptive coping styles. At high levels of adaptive coping styles, the association between academic stress and suicidal ideation was not significant. However, resilience negatively predicted suicidal ideation [R = .29, (R2 = .08), F(1, 499) = 19.94, p = .00] with academic stress showing a positive association with suicidal ideation at low and moderate levels of resilience, but for those with high resilience, academic stress was not associated with suicidal ideation. In sum, suicidal ideation is heightened by increased academic stress, with greater resilience ameliorating the tendency of academic stress resulting in suicidal ideation. Also, adopting maladaptive ways of coping promotes suicidal ideation among students, with resilience and adaptive coping strategies moderating the relationship between academic stress and suicidal ideation. It is therefore recommended that educational administrators, policy makers, lecturers, teachers, and tutors incorporate courses, teachings, and sessions that foster as well as inculcate resilience and efficient coping skills in pupils and students.

Evidence has shown that social anxiety significantly influences internet addiction among adolescent students. However, the boundary conditions that strengthen or weaken this association with internet addiction have not been fully understood, especially in sub-Saharan Africa. This study adopted a cross-sectional survey design to investigate the direct effect of social anxiety on internet addiction among adolescent students and the moderating role of family functioning in such relationships. A sample of ( N = 1800) students (age range 11–17 years; M = 15.30 years; SD = 1.99) from 10 secondary schools in Southeast Nigeria participated in this study. The participants completed the self-report measures of the Social Phobia Inventory, Family APGAR (adaptability, partnership, growth, affection, and resolve) Index, and Internet Addiction Test. Pearson correlation was used to determine the bivariate relationship among the study variables, while Hayes regression-based PROCESS macro was used for moderation analysis. Findings revealed that social anxiety was positively associated with internet addiction. Family functioning was negatively associated with internet addiction. Family functioning did not moderate the relationship between social anxiety and internet addiction. We concluded that reducing social anxiety and bolstering family functioning may be an effective strategy to lessen the vulnerability of adolescents to internet addiction.
