Can the Testing Effect for General Knowledge Facts Be Influenced by Distraction due to Divided Attention or Experimentally Induced Anxious Mood?

Studies on testing effect have showed that a practice test on study materials leads to better performance in a final test than restudying the materials for the same amount of time. Two experiments were conducted to test how distraction, as triggered by divided attention or experimentally induced anxious mood in the practice phase, could modulate the benefit of testing (vs. restudying) on the learning of interesting and boring general knowledge facts. Two individual difference factors (trait test anxiety and working memory (WM) capacity) were measured. Under divided attention, participants restudied or recalled the missing information in visually presented general knowledge facts, while judging whether auditorily presented items were from a pre-specified category. To experimentally induce anxious mood, we instructed participants to view and interpret negative pictures with anxious music background before and during the practice phase. Immediate and two-day delayed tests were given. Regardless of item type (interesting or boring) or retention interval, the testing effect was not significantly affected by divided (vs. full) attention or anxious (vs. neutral) mood. These results remained unchanged after taking into account the influences of participants' trait test anxiety and WM capacity. However, when analyses were restricted to the study materials that had been learnt in the divided attention condition while participants accurately responded to the concurrent distracting task, the testing effect was stronger in the divided attention condition than in the full attention condition. Contrary to previous studies (e.g., Tse and Pu, 2012), there was no WM capacity × trait test anxiety interaction in the overall testing effect. Theoretical and practical implications of these findings are discussed.

Why hope can reduce negative emotion? Could psychosocial resource be the mediator?

The interrelationship between hope, psychological resources and depression needs clarification. The current study aimed to examine the interrelationship using empirical data. A total of 139 Chinese adults living in the community were invited to fill in questionnaires measuring dispositional hope, psychological resources (i.e. optimism, self-efficacy, social support and positive affect) and negative emotion (i.e. negative affect and depression). Structural equation modelling showed that negative emotion is partially mediated between hope and psychological resources. A bootstrap-estimated analysis corrected for bias showed that negative emotion plays a mediation role between hope and psychological resources. Hope is directly and indirectly related to psychological resources via negative emotion. The potential of hope as an intervention to assist patients with depression to achieve their treatment goals is discussed.

Different mechanisms of risperidone result in improved interpersonal trust, social engagement and cooperative behavior in patients with schizophrenia compared to trifluoperazine.

AIM: Atypical antipsychotic treatment (e.g. risperidone) has been found to improve social functioning more than standard antipsychotic treatment. However, it is unclear which specific social behaviors are implicated in this improvement. The current study employed an interactive puzzle game to examine how social behaviors contribute to the improvement of social functioning by comparing patients receiving risperidone with those receiving trifluoperazine. METHODS: Scores on the Positive and Negative Syndrome Scale, executive functioning, and social functioning were obtained from 24 patients with schizophrenia receiving either risperidone (n = 12) or trifluoperazine (n = 12), before their social behavior was measured in the interactive Tangrams Game. Immediately after the Tangrams Game, participants filled in two questionnaires measuring their interpersonal trust and rejection toward their game partner. RESULTS: Patients receiving risperidone showed more social engagement, cooperative behavior and interpersonal trust toward their game partners than those receiving trifluoperazine. Additional multivariate analysis of variance revealed that lower affiliative behavior was a function of positive symptoms; interpersonal trust had an impact on social engagement but executive functioning did not explain lower interpersonal trust or social disengagement. CONCLUSION: Improvement of social competence by risperidone might be related to the enhancement of both social behaviors and interpersonal trust as well as better symptom resolution.
