Attachment, parenting, and separation--individuation in adolescence: a comparison of hospitalized adolescents, institutionalized delinquents, and controls

The authors compared parent-related perceptions by hospitalized adolescents (i.e., who were admitted to a specialized psychiatric unit; n = 50) and delinquent adolescents (i.e., who were placed at a juvenile treatment institution; n = 51) with adolescents from the general population (n = 51). All adolescents completed a broad set of measures of attachment, perceived parenting, and separation-individuation. Contrary to initial expectations, hospitalized adolescents scored higher than controls on indices of excessive autonomy. Ambivalence regarding issues of interpersonal closeness and distance was found among delinquent adolescents. In addition, hospitalized and delinquent adolescents were found to be struggling, each in their specific way, with attachment-related experiences of trauma. Finally, delinquent adolescents also showed a stage-appropriate form of potentially adaptive narcissism. These findings add to the growing consensus in the literature that associations between adolescent psychopathology and parent-related perceptions are typically complex and somewhat counterintuitive.     

Shaping reality vs. hiding from reality: Reconsidering the effects of trait need for closure on information search

For tentative and final decisions on real and artificial issues, three studies revealed a positive relation between trait need for closure and selective approach to supportive (vs. unsupportive) information. Specifically, individuals with high (vs. low) trait need for closure selected more decision-supportive information and less decision-challenging information for viewing. Furthermore, Study 1 showed that the effect of trait need for closure functioned independently of authoritarianism and dogmatism, and Study 3 showed that the effect of trait need for closure on selective approach to decision-supportive information was mediated by a current concern to get closure on the experimental issue. These findings provide a new understanding of how trait need for closure shapes post-decisional information search and decision making.     

An ecological analysis of knowing by wielding.

The ecological approach to perception, as developed by James Gibson, is described and applied to how one knows, by means of the haptic perceptual system, various properties of hand-held objects. Four sets of experiments are reviewed in which subjects reported on the extent, orientation, shape, and fractional components of unseen objects wielded freely. For each task, an invariant specific to the object property in question is identified in the structured arrays of rotational moments and strains produced by the act of wielding. Results are discussed in relation to the concepts of attention and stimulation, as reformulated by the ecological approach, and the general theory of perception as information pickup.     

Sex differences in the lateralized processing of facial emotion

Two reaction time tasks were administered to male and female normal subjects, involving judgments of facial emotion. In the Word-Face task, judgments of similarity or difference of a centrally presented emotion word and an emotional face presented in the left or right visual field were required, and in the Face-Face task, comparisons of a centrally presented and a laterally presented emotional face were required. Results were significant for the matching trials only. Reaction times to negative emotions were faster overall than to positive emotions, and an Emotional Valence by Visual Field interaction was found such that reaction times were faster for negative emotions in the left visual field and for positive emotions in the right visual field. This interaction was significant for the female but not the male subjects, although similar patterns were observed in both sexes. Further, an interaction of Gender, Task, and Emotional Valence was found, such that the two tasks had opposite effects for the two sexes. The Face-Face task appeared to inhibit the performance of the male subjects and facilitate the performance of the female subjects in terms of reaction time. It was suggested that specifying the target emotion by an emotional face elicits a greater emotional response on the part of the subject than specification by a word, and that this emotional elicitation may result in a reactive inhibition in the male subjects and in an elaboration of the emotional response in the female subjects.     

Effect of anesthetic drugs on time production and alpha rhythm

Ss produced time intervals before and during inhalation of low concentrations of anesthetic gases. The drugs increased time productions by raising the slope of the line representing produced against objective time. Alterations in time production were not accompanied by consistent changes in alpha rhythm, respiratory rate, heart rate, or body temperature. The findings argue against the’ alpha rhythm’s acting as the biological pendulum for the internal clock.     

Hospitalized psychiatric and medical patients and the clergy

Earlier research suggested that persons in a community with significant psychiatric disorders seek relief from their clergy as often as from trained mental-health professionals. In this research, contacts with clergy about current hospitalization by matched samples of inpatient psychiatric (N=51) and medical/surgical (N=50) patients were compared, as were responses to structured interviews about the importance of religion, religious affiliation, and participation, spiritual needs, and spiritual well-being. The findings suggest that the two groups were similar in demographics, the degree to which religion was a source of strength and comfort in their lives, and percentages reporting as having a clergy person; the group of hospitalized psychiatric patients was significantly less likely, however, than the sample of medical/surgical patients to have discussed their current hospitalization with their clergy persons. Possible causes for this difference as well as areas of further research are discussed.     

Selective perception by dynamic touch

Perceiving the length of a rod by dynamic touch is tied to the inertia tensorIij, a quantification of its resistance to rotational acceleration. Perception of the portion extending in front of the grasp has previously been ascribed to decomposing one component ofIij by attention. The tensorial nature of dynamic touch suggests that this ability must be anchored wholly in the tensor. Three experiments show that perceived partial length is a function of two components of the tensor, one tied primarily to magnitude and the other tied primarily to direction, whereas perceived whole length is a function of a magnitude component alone. Dynamic touch is characterized in terms of a haptic perceptual instrument that softly assembles to exploitIij differently depending on the intention, producing 1:1 maps that are appropriately scaled for each intention.     

Prime time advertisements: Repetition priming from faces seen on subject recruitment posters

Repetition priming is defined as a gain in item recognition after previous exposure. Repetition priming of face recognition has been shown to last for several months, despite contamination by everyday exposure to both experimental and control faces in the interval. Here we show that gains in face recognition in the laboratory are found from faces initially seen in a rather different context— on subject recruitment posters, even when the advertisements make no specific mention of experiments involving face recognition. The priming was greatest when identical pictures were shown in the posters and in the test phase, although different views of faces did give significant priming in one study. Follow-up studies revealed poor explicit memory for the faces shown on the posters. The results of these experiments are used to develop a model in which repetition priming reflects the process of updating representations of familiar faces.
