When power is undeserved: its effects on perception and social judgements

This paper explores the impact of the legitimacy of power position on powerholders' impressions, expectancies' confirmation processes, and decisions about subordinates in the context of a personnel selection process. Participants were assigned to a power position (they were told they will be representatives in a students conference and they will be able to select a mate to go also to the conference and to work under their supervision) on the basis of positive feedback regarding their supervisory skills (legitimate) or negative feedback regarding their supervisory skills (illegitimate). Two applicants were proposed as subordinates: one high in sociability and competence and the other low in both dimensions. Although participants in the two conditions noticed the superiority of one candidate over the other, illegitimate powerholders selected the least sociable and competent subordinate more often than legitimate powerholders. Illegitimate participants also request more information about the best than about the worse candidate. We interpret our findings in light of the larger literature suggesting an impact of illegitimacy on people's attempts to rationalize and justify their position as well as to perpetuate the existing social arrangement.     

Pramipexole: augmentation in the treatment of depressive symptoms

We describe a retrospective case series of three patients, two with bipolar depression and one with unipolar depression. Pramipexole is a Food and Drug Administration-approved antiparkinsonian agent, which, when used to augment antidepressants, would be considered an off-label use and should be discussed with the patient. These patients had robust responses to pramipexole augmentation of their treatment regimen. All three patients had been taking an atypical antipsychotic. The depressive symptoms were evaluated using the Hamilton Rating Scale for Depression.     

Social cognition in the first year

Although the study of infancy has answered many important questions about the human capacity for social cognition, the relatively young field of developmental social cognition is far from reaching its adulthood. With the merging of developmental, behavioral and neurocognitive sciences, some growing pains are in store. New work demonstrates that research into early social cognitive development must integrate various research fields and methods in order to achieve a more robust understanding of the nature and parameters of human social cognition.     

Economic pressure in African American families: a replication and extension of the family stress model

This study of 422 two-caregiver African American families, each with a 10-11-year-old focal child (54% girls), evaluated the applicability of the family stress model of economic hardship for understanding economic influences on child development in this population. The findings generally replicated earlier research with European American families. The results showed that economic hardship positively relates to economic pressure in families. Economic pressure was related to the emotional distress of caregivers, which in turn was associated with problems in the caregiver relationship. These problems were related to disrupted parenting practices, which predicted lower positive child adjustment and higher internalizing and externalizing symptoms. The results provide significant support for the family stress model of economic hardship and its generalizability to diverse populations.     

Deaf poor readers' pattern reversal visual evoked potentials suggest magnocellular system deficits: implications for diagnostic neuroimaging of dyslexia in deaf individuals

Deafness and developmental dyslexia in the same individual may jointly limit the acquisition of reading skills for different underlying reasons. A diagnostic marker for dyslexia in deaf individuals must therefore detect the presence of a neurobiologically based dyslexia but be insensitive to the ordinary developmental influences of deafness on reading skill development. We propose that the functional status of the magnocellular visual system in deaf individuals is potentially such a marker. We present visual evoked potential (VEP) evidence that adult deaf poor readers as a group display magnocellular system deficits not observed in deaf good readers. We recorded pattern-reversal VEPs to high- and low-contrast checkerboard stimuli, which primarily activate the parvocellular and magnocellular pathways, respectively. Principal components analysis of these VEPs produced a time-ordered sequence of three early components that displayed interactions between reading skill and stimulus contrast across multiple scalp recording sites. Deaf poor readers displayed an abnormal absence of contrast-sensitive VEP responses at occipital sites during early visual processing (75 ms poststimulus), whereas deaf good readers showed the expected early contrast-sensitive occipital VEP responses. Over the subsequent 225 ms, the occipital VEP behavior of deaf poor readers closely approximated that of deaf good readers. The VEPs of deaf poor readers were apparently characterized by delayed responses to low-contrast stimuli compared with deaf good readers. Our results provide the first neurobiological evidence that developmental dyslexia exists within the deaf population and is associated with the same underlying magnocellular system deficit that has been observed in hearing dyslexics. Direct neural imaging of the status of the magnocellular visual system in deaf individuals may eventually provide differential diagnosis of developmental dyslexia in the deaf population.     

Lateralized perceptual organization deficits on the global-local task in schizotypal personality disorder

Right and left hemisphere contributions to perceptual organization functions were examined using a divided-attention version of the global-local task in a sample of 21 unmedicated participants diagnosed with schizotypal personality disorder (SPD) and 20 controls. The SPD participants showed an abnormal global processing advantage. When the visual angle of the hierarchical stimuli was increased from 3 degrees to 9 degrees, the controls showed an increasing local processing advantage, but the SPD participants continued to show an abnormal global processing advantage. These findings suggest a local processing deficit on divided-attention versions of the global-local task in schizophrenia spectrum disorders. Female SPD participants, who had less severe interpersonal deficit symptoms, showed a more abnormal global processing advantage. Hemispheric and processing resource mechanisms that might explain these findings are discussed.     

Comparison of ganglion cell signals and psychophysical localization of moving targets can help define central motion mechanisms

Vernier acuity thresholds can be related to visibility of targets. This is considered in relation to retinal signals. Spatial precision of macaque ganglion cell responses to moving targets was assessed by neurometric analysis and compared with psychophysical performance. Under some conditions the amplitude of ganglion cell signals per se may relate target visibility to spatial precision of psychophysical performance. Other conditions are more complex; we suggest central mechanisms may adapt their properties, eg their dimensions, depending on the stochastic properties of ganglion cell signals. Thus, the relation of Vernier acuity to the visibility of targets is a rule of thumb which has a complex relation to physiological substrates.     

The impact of yoga on the professional and personal life of the psychotherapist

This study explored the impact of a regular practice of yoga in the personal and professional lives of psychotherapists. Six licensed psychotherapists were interviewed about their perceptions regarding the influence of their yoga training on their personal and professional lives. These effects were then categorized into common patterns that emerged as four themes addressing professional growth and the self care of the therapist. These themes are: internal/self awareness, balance, acceptance of self and others, and yoga as a way of life.     

Effects of openness, problem solving, and blaming on learning: an experiment in China

Researchers have considered interdependence and interaction among individuals and groups as critical for promoting learning in organizations. In an experiment with 80 participants in China, the present authors found that (a) open discussion compared with avoiding discussion and (b) problem solving compared with blaming stimulated the exploration, integration, and adoption of alternative ideas in addition to strengthening interpersonal relationships. The results also indicated the possibility that openness and problem solving have these effects by developing a perceived cooperative interdependence that encourages people to believe that incorporating alternative ideas can help them succeed. Avoidance and blaming, on the other hand, seemed to result in a competitive struggle to see who could impose their ideas on the other, leaving people committed to their original thinking.
