Individual differences in empathizing and systemizing in Japanese children: Psychometric properties of the children's versions of the Empathy Quotient (EQ) and Systemizing Quotient (SQ)

In the present study, children's versions of the Empathy Quotient (EQ‐C) and the Systemizing Quotient (SQ‐C) were administered to 626 Japanese children (313 boys, 313 girls) aged 6–15 years. The psychometric properties of both quotients were found to be satisfactory. Sex differences were found in the scores for both quotients. The girls scored higher than the boys on the EQ‐C, while the boys scored higher than the girls on the SQ‐C. Proportions of cognitive styles, which were determined by differences between the standardized scores of the EQ‐C and SQ‐C, showed clear sex differences. The proportion of participants whose cognitive style was classified as empathizing‐dominant was greater for the girls, while the proportion of participants classified as systemizing‐dominant was greater for the boys. No developmental changes were found in either the scores for the EQ‐C and SQ‐C or the proportions of the cognitive styles.     

A facilitative effect of negative affective valence on working memory

Gotoh, F., Kikuchi, T. &Olofsson, U. (2010). A facilitative effect of negative affective valence on working memory. Scandinavian Journal of Psychology, 51, 185–191. Previous studies have shown that negatively valenced information impaired working memory performance due to an attention‐capturing effect. The present study examined whether negative valence could also facilitate working memory. Affective words (negative, neutral, positive) were used as retro‐cues in a working memory task that required participants to remember colors at different spatial locations on a computer screen. Following the cue, a target detection task was used to either shift attention to a different location or keep attention at the same location as the retro‐cue. Finally, participants were required to discriminate the cued color from a set of distractors. It was found that negative cues yielded shorter response times (RTs) in the attention‐shift condition and longer RTs in the attention‐stay condition, compared with neutral and positive cues. The results suggest that negative affective valence may enhance working memory performance (RTs), provided that attention can be disengaged.
