Minority influence: a meta-analytic review of social influence processes.

A meta-analytic review of 97 minority influence experiments evaluated the processes by which sources advocating deviant, minority opinions exert influence. Minority impact was most marked on measures of influence that were private from the source and indirectly related to the content of the appeal and less evident on direct private influence measures and on public measures. This attenuated impact of minorities on direct private and public measures suggests that in response to normative pressures, recipients avoided aligning themselves with a deviant source. Mediator analyses revealed that minorities perceived as especially consistent in the advocacy of their views were especially influential. The relation between normative and informational pressures in the minority influence paradigm was discussed.

Pursuit eye movements in chronic schizophrenics: relationship between increased saccades and negative symptoms.

Smooth pursuit eye movements of chronic schizophrenics (n = 16) and controls (n = 10) were recorded while subjects tracked a sinusoidally-moving target. Negative symptoms in schizophrenics were rated using the Schedule for the Assessment of Negative Symptoms. An increased frequency of smooth pursuit eye movement abnormalities was found in the schizophrenic group, including greater variability of gain and more frequent and larger saccades. Frequency of saccades was positively correlated with the Negative Symptoms scales for attentional impairment and alogia. The results confirm findings of eye movement dysfunction in schizophrenics and provide new evidence that the motor and cognitive dysfunctions of schizophrenia may be related.

Marginal and mindful: deviants in social interactions.

Master status people's behavior, physical appearance, or life circumstance is statistically unusual and centrally defining (e.g., the physically attractive, the obese, the intellectually gifted, the facially scarred, the talented, the athletic, Blacks, gays, the wealthy, rape and incest victims). These individuals were paired with people without such conditions. Each pair was left alone on a pretext and covertly videotaped. Pairs were then separated; each member spontaneously recalled information about her partner and the experimental room and provided a record of her thoughts and feelings during the interaction. As hypothesized, all master status Ss were particularly likely to be mindful in social interactions; they recalled detailed information about the situation and often took their partner's perspective during the interaction. The positive or negative connotations of the master status conditions were irrelevant in predicting Ss cognitions (mindfulness) but were critical in determining Ss behaviors (interaction strategies).

Equivocal karyotype analysis and prenatal counseling.

An uncertain amniotic fluid karyotype analysis may result in months of intense anxiety for the parents. An illustrative case demonstrates that thorough and accurate diagnostic steps, active involvement of the family physician, coordination of counseling efforts by all involved health-care professionals and attention to the social and financial concerns of the parents are helpful in this situation.
