Individual differences in holistic processing predict face recognition ability

Why do some people recognize faces easily and others frequently make mistakes in recognizing faces? Classic behavioral work has shown that faces are processed in a distinctive holistic manner that is unlike the processing of objects. In the study reported here, we investigated whether individual differences in holistic face processing have a significant influence on face recognition. We found that the magnitude of face-specific recognition accuracy correlated with the extent to which participants processed faces holistically, as indexed by the composite-face effect and the whole-part effect. This association is due to face-specific processing in particular, not to a more general aspect of cognitive processing, such as general intelligence or global attention. This finding provides constraints on computational models of face recognition and may elucidate mechanisms underlying cognitive disorders, such as prosopagnosia and autism, that are associated with deficits in face recognition.     

Brain activations associated with sign production using word and picture inputs in deaf signers

Effective literacy education in deaf students calls for psycholinguistic research revealing the cognitive and neural mechanisms underlying their written language processing. When learning a written language, deaf students are often instructed to sign out printed text. The present fMRI study was intended to reveal the neural substrates associated with word signing by comparing it with picture signing. Native deaf signers were asked to overtly sign in Chinese Sign Language (CSL) common objects indicated with written words or presented as pictures. Except in left inferior frontal gyrus and inferior parietal lobule where word signing elicited greater activation than picture signing, the two tasks engaged a highly overlapping set of brain regions previously implicated in sign production. The results suggest that word signing in the deaf signers relies on meaning activation from printed visual forms, followed by similar production processes from meaning to signs as in picture signing. The present study also documents the basic brain activation pattern for sign production in CSL and supports the notion of a universal core neural network for sign production across different sign languages.     

From autonomy to creativity: a multilevel investigation of the mediating role of harmonious passion

Building on self-determination theory, we theorized about and demonstrated, through 2 multilevel field studies, the pivotal role of harmonious passion in translating organizational autonomy support and individual autonomy orientation into job creativity. Results based on 3-level data from 856 members in 111 teams within 23 work units of a porous metal company (Study 1) and from 525 employees in 98 teams of 18 branches of a large commercial bank (Study 2) revealed 2 major findings. First, organizational autonomy support from a higher organizational level (unit or branch) compensated for the effect of autonomy support from a lower organizational level (team) or individual autonomy orientation on employees' harmonious passion. Second, harmonious passion mediated the interactive effects of unit (branch) autonomy support and team member autonomy orientation, of team autonomy support and team member autonomy orientation, and of unit (branch) autonomy support and team autonomy support on individual creativity. We discuss the theoretical and practical implications of these findings in the organizational context.     

Acceptance and Commitment Therapy for generalized anxiety disorder in older adults: a preliminary report

Some evidence suggests that acceptance-based approaches such as Acceptance and Commitment Therapy (ACT) may be well-suited to geriatric generalized anxiety disorder (GAD). The primary goal of this project was to determine whether ACT was feasible for this population. Seven older primary-care patients with GAD received 12 individual sessions of ACT; another 9 were treated with cognitive-behavioral therapy. No patients dropped out of ACT, and worry and depression improved. Findings suggest that ACT may warrant a large-scale investigation with anxious older adults.

Parents, teachers, and peers and early adolescent runaway in Hong Kong

Parental monitoring, teacher support, classmate support, and friend relationship presumably affect adolescents' runaway from home. According to social control theory, social control based on conventional social norms would prevent adolescent runaway, but association with friends may erode such control. This expectation appears to hold true in a sample of Grade 7 students in Hong Kong; parental monitoring and classmate support reduced runaway risk whereas friend relationship raised the risk. These findings emerged from a causal model that controlled for a latent predisposition that commonly affected parental monitoring, friend relationship, and runaway risk. Further analysis indicates that the preventive effect of parental monitoring was stronger on adolescents born on the Chinese mainland than in Hong Kong, and the effect of friend relationship was stronger on the Hong Kong born than the mainland born. Conceivably, a socially controlling culture bolsters the preventive effect of social control.
