AbstractDeficits in social cognition may impair the ability to negotiate social transactions and relationships and contribute to socio emotional difficulties experienced by some post‐institutionalized children. We examined false belief and emotion understanding in 40 institutional care‐adopted children, 40 foster care‐adopted children and 40 birth children. Both groups of adopted children were adopted internationally. Controlling for verbal ability, post‐institutionalized children scored lower than birth children on a false belief task. Almost half of the post‐institutionalized children performed below chance levels. The foster care group did not differ from either group on false belief understanding. The groups did not differ on emotion understanding after controlling for verbal ability. The results suggest that some post‐institutionalized children are delayed in false belief understanding.

Purpose
The purpose of this study was to examine associations between fear of terrorism and several predictors (gender and nationality) and outcomes (moral disengagement, authoritarianism, aggression and social anxiety) in the USA and South Korean young adults. Of particular interest were the potential moderating and mediating roles of moral disengagement between fear of terrorism and the other outcomes.


Design/methodology/approach
Samples of 251 college students from the USA and 211 college students from South Korea completed survey packets including measures of fear of terrorism, moral disengagement, authoritarianism, aggression and social anxiety.


Findings
US participants expressed greater concern about a terrorist threat to their country, while South Koreans worried more about terrorist threats to their family or themselves. Females in both countries reported greater fear of terrorism and social anxiety. In both countries, fear of terrorism was associated with aggression, social anxiety and moral disengagement. Mediation analyses showed that fear of terrorism exerted a significant direct effect and an indirect effect via moral disengagement on aggression and authoritarianism in the US sample. Moderation analyses revealed that moral disengagement moderated the relationship between fear of terrorism and social anxiety in the Korean sample.


Research limitations/implications
This study has the common limitations of cross-sectional studies; i.e. it cannot prove causal relationships.


Practical implications
The findings support Albert Bandura's view that efforts to address the excesses of counterterrorism and other negative outcomes of fear of terrorism, attending to issues of moral disengagement may be helpful.


Originality/value
The authors findings provide support for the view that fear of terrorism is associated with negative psychological and social outcomes and that moral disengagement can play an important role in those negative outcomes. Moreover, it adds to evidence that the negative role of moral disengagement shows considerable generalizability across gender and two very different cultures.

AbstractThe event‐related potential (ERP) effect of mismatch negativity (MMN) was the first electrophysiological probe to evaluate cognitive processing (change detection) in newborn infants. Initial studies of MMN predicted clinical utility for this measure in identification of infants at risk for developmental cognitive deficits. These predictions have not been realized. We hypothesized that in sleeping newborn infants, measures derived from wavelet assessment of power in the MMN paradigm would be more robust markers of the brain's response to stimulus change than the ERP‐derived MMN. Consistent with this premise, we found increased power in response to unpredictable and infrequent tones compared to frequent tones. These increases were present at multiple locations on the scalp over a range of latencies and frequencies and occurred even in the absence of an ERP‐derived MMN. There were two predominant effects. First, theta band power was elevated at middle and late latencies (200 to 600 ms), suggesting that neocortical theta rhythms that subserve working memory in adults are present at birth. Second, late latency (500 ms) increased power to the unpredictable and infrequent tones was observed in the beta and gamma bands, suggesting that oscillations involved in adult cognition are also present in the neonate. These findings support the expectation that frequency dependent measures, such as wavelet power, will improve the prospects for a clinically useful test of cortical function early in the postnatal period.
