Social support from a friend,perceived support,and social problem solving

This research combined experimental and correlational methods to investigate the effects of social support on social problem-solving effectiveness and perceived stress. During a wait period, college students were given the opportunity to work on practice items from a mildly stressful social problem-solving task, either alone or in the company of a close friend. Participants and friends were allowed to talk about the practice items but were not required to do so, and supportive transactions were tape recorded and content analyzed. All students then completed social problem-solving and perceived stress items alone. Participants who waited with friends did not show superior problem-solving effectiveness unless companions provided particular supportive behaviors. Participants with high perceived support scores rated the experiment as less stressful than those with low scores, but perceived support was not related to companions' actual supportive behaviors. The results were discussed in terms of implications for understanding the mechanisms of social support.     

The effect of orientation on visual and tactual braille recognition

Five experiments are reported in which subjects matched tangible or visible braille characters against either visual or tangible arrays. In both modalities recognition was impaired when the characters were tilted, but visual performance was superior to that for touch. Touch may be more sensitive than vision to tilt, since very small deviations from the upright decreased recognition accuracy. Orientation influenced pattern recognition with and without prior information about orientation. Tilting patterns slowed down recognition for tactual-visual matching, but only when orientation was studied with repeated measures. The results are consistent with the hypothesis that it is difficult to code braille patterns tactually as global outline shapes.     

Facial imagery and personality development.

The empirical relationship between judgments obtained with a motorized facial-distortion mirror and relevant personality and rating measures was examined. Subjects were 88 school children. The findings indicated general trend differences between males and females in perceiving facial distortion shown in a mirror. Although not statistically significant, a relationship between teachers' ratings on hygiene, self-concept, sociability, and two scales of the High School Personality Questionnaire were noted.     

Confirmatory factor analyses of DSM-IV Cluster C personality disorder criteria

Notwithstanding its research and clinical relevance, the dimensionality and validity of the DSM-IV avoidant, dependent, and obsessive-compulsive personality disorders (PDs) criteria is still a largely unexplored topic. The aim of this study was to test the factor structure for DSM-IV Cluster C PD criteria in a sample of 641 consecutively admitted outpatients. Factor analysis results suggested that avoidant, dependent, and obsessive-compulsive PDs share a common latent dimension, and supported the three-factor structure of both observer and self-report ratings of DSM-IV Cluster C PD criteria. The pattern of factor loadings, however, was different from the one expected according to the DSM-IV classification.     

The dental anxiety scale and effects of dental fear on salivary cortisol

Only a few studies have investigated use of the Dental Anxiety Scale in dental fear-induced neuroendocrine changes. The present study examined 19 female patients, each at two timepoints across an educational and a treatment session within periodontitis therapy. Subjective measures included a visual analogue scale, the STAI State scale, and the Dental Anxiety Scale. Salivary cortisol was measured in parallel across all four timepoints. Although patients were significantly more aroused and anxious prior to the treatment session, salivary cortisol remained unchanged. However, patients with high Dental Anxiety were significantly more aroused and anxious and showed significantly higher salivary cortisol during the educational session than those with low scores on Dental Anxiety. In conclusion, the Dental Anxiety Scale differentiated mean neuroendocrine change between patients scoring low and high for Dental Anxiety and its use as an accurate tool to identify patients with high dental anxiety should be further studied predictively.     

Visual search for singleton feature targets within and across feature dimensions

Three experiments investigated visual search for singleton feature targets. The critical dimension on which the target differed from the nontargets was either known in advance or unknown—that is, the critical difference varied eitherwithin a dimension oracross dimensions. Previous work (Treisman, 1988) had shown that, while the search reaction time (RT) functions were flat in both conditions, there was an intercept cost for the cross-dimension condition. Experiment 1 examined whether this cost would disappear when responses could be based on the detection ofany (target—nontarget) difference in the display (by requiring a “heterogeneity/homogeneity” decision). The cost remained. This argues that pop-out requires (or involves) knowledge of the particular dimension in which an odd-one-out target differs from the nontargets; furthermore, that knowledge is acquired through the elimination of dimensions not containing a target. In Experiment 2, the subjects had to eliminate (or ignore) one potential source of difference in order to give a positive response (displays could contain a “noncritical” difference requiring a negative response). The result was a comparatively large cost in the within-dimension (positive) condition. This can be taken to indicate that popout as such does not make available information as to the particular feature value in which the target differs from the nontargets. Experiment 3 examined whether search priorities can be biased in accordance with advance knowledge of the likely source of difference. The subjects were found to have a high degree of top-down control over what particular dimension to assign priority of checking to. The implication of the results for models of visual search and selection are discussed.     

A measure of relational competence for community-dwelling elderly

A measure of relational competence was developed to assess the skills necessary for peer friendship development among the elderly. Participants were required to respond to a series of social problem vignettes that were constructed to tap empathy, assertion, and role-taking skills. Validation data were collected as part of a larger project designed to establish indigenous, elderly peer-support telephone dyads among low-income, community-dwelling elderly women. Results indicated that the measure of relational competence was related to initial friendship formation, telephone conversational skills, and rated social competence as determined by judges' ratings of 2 telephone conversations between participants and staff members. The research illustrates the usefulness of moving away from trait conceptions of social competence to a more focused consideration of particular task demands and the skills needed to solve age-linked social problems.     

Perspective taking, pictures, and the blind

Congenitally blind, late blind, and blindfolded sighted controls attempted a Piagetian perspective-taking (three-mountain) task. Piaget used the term perspective to mean point of view (Piaget & Inhelder, 1967, p. 210), and the present usage does not imply linear perspective. Subjects used raised-line drawings to depict alternative points of view of an array of three geometric solid forms (cube, cone, and ball). They then identified the point of view of raised-line drawings. The effect of visual status on accuracy was nonsignificant for both response measures. Using alternating vision of the array and drawings, sighted subjects in a control condition performed like the congenitally blind. However, congenitally blind individuals did require more time than the other subjects for the perspective-taking task. In an additional experiment, no difference was found between the three groups in the accuracy or speed of tactile shape matching. The results suggest that visual imagery and visual experience are not necessary for tactile perspective taking.
