Young children's difficulty with inhibitory control in a social context1

Abstract: The authors’ prior research has documented that young children's behaviors in the Dimensional Change Card Sorting (DCCS) task can be influenced by their observation of another person performing the task and has suggested that young children committed perseverative errors in a social context. The present study explored whether children who committed perseverative errors in the social context also committed perseverative errors in the standard DCCS task. Three‐ and 4‐year‐old children were given the standard DCCS and the observation version of the DCCS, and the relationship between them was examined. The results showed that the correlation between these two tasks was significant. Furthermore, 4‐year‐old children displayed more difficulty in the observation version than in the standard DCCS, whereas 3‐year‐olds did not. The results are discussed in terms of the development of inhibitory control and social cognition.     

Cultural Transmission in International Organizations Impact of Interpersonal Communication Patterns in Intergroup Contexts

This study examined how organizational cultures are transmitted and maintained through interactions among organizational members across intergroup boundaries. The major hypothesis of interest was that the total number of individuals' out-group communication network links predicts the degree of individual-out-group transmission of work-related values and beliefs. The research design involved a survey of workers in international organizations with bicultural workforces (U.S. and Japanese). A total of 118 responses were submitted to a series of multiple regression analyses. The results provided evidence to support the relationship between communication and cultural transmission. Theoretically, it addressed two issues that have not been dealt with in social influence theories. First, it identified different types of social influence: agreement, accuracy, and congruency derived from the coorientation model. Second, it identified specific conditions under which social influence takes place by examining relational proximity in three different types of networks.     

The effects of attention retraining on depressive mood and cortisol responses to depression‐related stimuli1

Although it has been reported that attentional bias at an early stage is found in depression, no study has investigated the effects of modification of attentional bias at an early stage on depressive mood and cortisol response to a stressor. Therefore, this study tested the hypotheses that the modification of attentional bias at an early stage would reduce depressive mood and cortisol response. Fifty‐three participants were allocated alternately either to the training or the control group. They were administered attention retraining for modification of attentional bias or a sham attention task, and then underwent a stress task. With respect to depressive mood response, depressive mood increased in response to a stress task in the control group, while for high‐dysphoric participants in the training group, depressive mood response remained constant. These results indicate that attention retraining is efficacious for reducing depressive mood response. With respect to cortisol response, the percentage change in cortisol is associated with the amount of change in the attentional bias index scores. The results suggest the possibility that attention retraining could reduce cortisol response.
