Nonspatial attributes of stimuli can influence spatial limitations of attentional control

A wide variety of psychophysical and neurophysiological research suggests that when stimuli are very close together, they cannot be attended separately. As a consequence, they cannot be represented as individual items with specific feature information associated with them. Here we report evidence that the spatial control of attention can be modulated by nonspatial features of the stimuli (such as color and luminance). Observers shifted attention from item to item within highly dense arrays of stimuli. Performance was extremely poor when all of the items in the array were an identical gray. In contrast, performance improved when items differed in color. This finding indicates that nonspatial features, such as color, can facilitate spatial selection and suggests moreover that features can be reliably associated with particular items even when the items are densely clustered.     

Watch,wait, and wonder: Testing the effectiveness of a new approach to mother–infant psychotherapy

This research compared two forms of psychodynamic psychotherapeutic interventions for 67 clinically referred infants and their mothers. One was an infant‐led psychotherapy delivered through a program called Watch, Wait, and Wonder (WWW). The other was a mother–infant psychotherapy (PPT). Infants ranged in age from 10 to 30 months at the outset of treatment, which took place in weekly sessions over approximately 5 months. A broad range of measures of attachment, qualities of the mother–infant relationship, maternal perception of parenting stress, parenting competence and satisfaction, depression, and infant cognition and emotion regulation were used. The WWW group showed a greater shift toward a more organized or secure attachment relationship and a greater improvement in cognitive development and emotion regulation than infants in the PPT group. Moreover, mothers in the WWW group reported a larger increase in parenting satisfaction and competence and decrease in depression compared to mothers receiving PPT. Both WWW and PPT were successful in reducing infant ‐presenting problems, decreasing parenting stress, and reducing maternal intrusiveness and mother–infant conflict. Some potential reasons for the differential treatment effects and the theoretical, clinical, and methodological implications from the findings are discussed. ©1999 Michigan Association for Infant Mental Health.     

Heuristic processing of distinctiveness information in minority and majority influence

The role of distinctiveness information in majority and minority influence was studied. Students read a message containing strong or weak arguments advocated by a minority or majority source. The communicator's minority (majority) status was said to be either distinctive to the target topic or nondistinctive across topics. Major dependent variables were attitude judgments and cognitive responses. Across conditions, messages were processed systematically, and a majority communicator tended to be more persuasive than a minority communicator. Most importantly, high distinctiveness led to greater influence than low distinctiveness, and this effect was independent of argument strength and minority versus majority status. Theoretical and applied implications of these findings are discussed. © 1998 John Wiley & Sons, Ltd.
