Emotion-recognition abilities and behavior problem dimensions in preschoolers: Evidence for a specific role for childhood hyperactivity

Facial emotion-recognition difficulties have been reported in school-aged children with behavior problems; little is known, however, about either this association in preschool children or with regard to vocal emotion recognition. The current study explored the association between facial and vocal emotion recognition and behavior problems in a sample of 3 to 6-year-old children. A sample of 57 children enriched for risk of behavior problems (41 were recruited from the general population while 16 had been referred for behavior problems to local clinics) were each presented with a series of vocal and facial stimuli expressing different emotions (i.e., angry, happy, and sad) of low and high intensity. Parents rated children’s externalizing and internalizing behavior problems. Vocal and facial emotion recognition accuracy was negatively correlated with externalizing but not internalizing behavior problems independent of emotion type. The effects with the externalizing domain were independently associated with hyperactivity rather than conduct problems. The results highlight the importance of using vocal as well as facial stimuli when studying the relationship between emotion-recognition and behavior problems. Future studies should test the hypothesis that difficulties in responding to adult instructions and commands seen in children with attention deficit/hyperactivity disorder (ADHD) may be due to deficits in the processing of vocal emotions.     

Hand Grip and Load Force Coordination of the Ipsilesional Hand of Chronic Stroke Individuals

Object manipulation depends on a refined control of grip force (GF) and load force (LF). After a brain injury, the GF control is altered in the paretic hand but what happens with the non-paretic hand is still unclear. In this study, we compared the GF control and GF–LF coordination of the non-paretic hand of 10 stroke individuals who suffered right brain damage (RBD) and 10 who suffered left brain damage (LBD), with 20 healthy individuals during lifting and oscillation task, using an instrumented object. GF was recorded with a force transducer, and LF was estimated from the object weight and acceleration. Overall, the ipsilesional hand of stroke individuals, independent of the lesion side, presented similar GF control and GF–LF coordination. However, LBD individuals took longer to start lifting the object, which may be due to the need of more time to obtain somatosensory information from the contact with the object. The findings indicate that stroke individuals preserve their ability to control and coordinate GF and LF when using their ipsilesional hand for object manipulation and the left hemisphere may play an essential role in the processing of somatosensory information needed for the GF control.     

The Initial Validation of a Liking of Children Scale

This article describes the initial research involving the Barnett Liking of Children Scale (BLOCS), a 14-item measure that assesses the extent to which individuals have a favorable attitude toward children. The BLOCS was found to have acceptable internal and test-retest reliability, in addition, individual differences in the liking of children were associated with an individual's gender, sex-role orientation, and a variety of attitudes concerning childrearing and children's behavior. Future research involving the BLOCS is briefly discussed.     

Adaptive expertise: Effects of type of experience and the level of theoretical understanding it generates

This research investigates the development of transferable—“adaptive”—expertise. The study contrasts problem-solving performance of two kinds of experts (business consultants and restaurant managers) on novel problems at the intersection of their two domains, as well as a group of novices (non-business undergraduates). Despite a lack of restaurant experience, consultants performed better than restaurant managers and undergraduates, even though the problems concerned a restaurant. Process measures suggest this was due to the use of more theoretical reasoning. Analyses show this resulted from differences in work experience and not other factors (e.g., education). We discuss aspects of experience that might be responsible for development of theoretical understanding and, thus, expertise that transfers to novel problems. One possible explanation, consistent with existing research from multiple approaches, is that to transfer to novel problems, experience must include substantive variability. The social context of learning may also play a role.     

Tolerance and the distributed sorites

Synthese - On some accounts of vagueness, predicates like “is a heap” are tolerant. That is, their correct application tolerates sufficiently small changes in the objects to which they...     

Perceived freedom-responsibility covariation among Cypriot adolescents

Participants were 67 Cypriot adolescents who responded to propositions regarding positive, negative, and noncontingent relations between freedom and responsibility. The authors framed items so that half dealt with freedom given responsibility, and the other half dealt with responsibility given freedom. Results indicated participants were more likely to endorse positive-contingency items than they were negative and noncontingency items when items were framed around freedom given responsibility. However, when items were framed around responsibility given freedom, no such differences emerged. The authors discuss results relative to cultural and sociopolitical differences and similarities between children in Cypress and participants in the United States and implications concerning the present study and previous studies regarding these constructs.     

Correlates of suicidality among patients with psychotic depression

The independent association of age and other factors with suicidality in patients with major depression with psychotic features was examined. Of the 183 study participants, 21% had a suicide attempt during the current episode. Male gender, Hispanic background, past suicide attempt, higher depression scores, and higher cognitive scores were each independently associated with greater intensity of current suicidality. Older age was independently associated with a lower risk of a lifetime suicide attempt. These findings reinforce the evidence that patients with psychotic depression are at high risk for suicide and underscore the importance of examining correlates of suicidality specific to patients with psychotic depression.
