Recalibration of the convergence system.

Adaptation to convergence-altering prism spectacles was studied. The subjects were trained for 8 min with either convergence-increasing or convergence-decreasing prisms. Before and after training they estimated the distance to a binocular dot varying in the stimulus it provided to convergence. Both the preadaptation and postadaptation estimates showed that the reciprocal of estimated target distance is linearly related to convergence. Further there was a consistent change in the direction of adaptation expected from the preadaptation to the postadaptation test. This change was accounted for in terms of a recalibration of the effective absolute convergence level.     

Sequence learning in Parkinson's disease: the effect of spatial stimulus-response compatibility

Patients with Parkinson's disease (PD) have repeatedly demonstrated reduced sequence-specific learning effects in serial reaction time tasks (SRTs). Previous research with PD patients has mainly employed the 'classical' SRT task, involving a spatially compatible assignment of stimuli and responses. From cognitive research, it is known that spatial compatibility triggers rapid, automatic responses in the direction of the stimulus. Automatic responding has shown to be disinhibited in PD patients and may therefore interfere with stimulus anticipation during the learning process. The aim of the present study was to test this hypothesis by investigating if reduced sequence-specific learning depends on spatial stimulus-response compatibility. PD patients and age-matched controls were examined either with an SRT variant involving central stimulus presentation, thereby preventing automatic linking of stimulus and response locations, or with a spatially compatible SRT task. Patients showed reduced sequence-specific learning effects only when the stimulus-response assignment was spatially compatible. This pattern of results confirms the hypothesis that sequence learning deficits in PD may result from a predominance of automatic response activation over learning-based stimulus anticipations during the learning phase.

School-Based Intervention for Social Skills in Children from Divorced Families

Divorce is an increasingly prevalent occurrence in society that has the potential to result in many adverse short- and long-term consequences for children and their parents. Social skills, such as those with peers, are one of the problems that may emerge for children of divorce. Despite this growing problem, there is a paucity of research available to effectively address the social skills needed to build and maintain positive peer interactions and subsequent relationships in students whose parents are no longer married. It was hypothesized that a social skills training program would be effective in remediating social skill deficits related to building relationships with peers in students from divorced families. The purpose of this study was to employ COPE, a school-based social skills program, to examine the effect on social skills in elementary students whose parents are divorced. Results of the social skills intervention indicated that the treatment was effective for most participants, but generalization of the COPE program had mixed results.     

Gender and orientation stereotypes bias source-monitoring attributions

Four experiments were conducted to determine whether gender stereotypes influence source-monitoring decision processes. Statements that were consistent with a male were more often correctly attributed to a male source and less frequently correctly attributed to a female. The reverse was true for items traditionally associated with a female. Both of these biases were reversed if participants believed the speaker was either a gay male or a lesbian female. These effects persisted under divided attention during test, suggesting that they are caused by automatic influences. But these biases were partially attenuated when participants first considered the detrimental impact of stereotypes. Because these biases were absent for gender-neutral statements, the results from this study show that the content of a memory can influence judgements about the context in which something was learned. The authors argue that the data are most consistent with a heuristic, early selection process that can be influenced by a conscious, late correction process (e.g., Jacoby, Kelly, & McElree, 1999).
