Are variations among right-handed individuals in perceptual asymmetries caused by characteristic arousal differences between hemispheres?

We propose that much of the variance among right-handed subjects in perceptual asymmetries on standard behavioral measures of laterality arises from individual differences in characteristic patterns of asymmetric hemispheric arousal. Dextrals with large right-visual-field (RVF) advantages on a tachistoscopic syllable-identification task (assumed to reflect characteristically higher left-hemisphere than right-hemisphere arousal) outperformed those having weak or no visual-field asymmetries (assumed to reflect characteristically higher right-hemisphere than left-hemisphere arousal). The two groups were equal, however, in asymmetries of error patterns that are thought to indicate linguistic or nonlinguistic encoding strategies. For both groups, relations between visual fields in the ability to discriminate the accuracy of performance followed the pattern of syllable identification itself, suggesting that linguistic and metalinguistic processes are based on the same laterally specialized functions. Subjects with strong RVF advantages had a pessimistic bias for rating performance, and those with weak or no asymmetries had an optimistic bias, particularly for the left visual field (LVF). This is concordant with evidence that the arousal level of the right hemisphere is closely related to affective mood. Finally, consistent with the arousal model, leftward asymmetries on a free-vision face-processing task became larger as RVF advantages on the syllable task diminished and as optimistic biases for the LVF, relative to the RVF, increased.     

Family origins of adolescent self-criticism and its continuity into adulthood

We used a prospective longitudinal design to examine the relation between parenting experiences at age 5 and level of self-criticism at age 12 and the stability of self-criticism from age 12 to age 31 in 156 subjects. The results showed that mothers' reports of parenting behaviors that reflect restrictiveness and rejection were related to the development of self-criticism, particularly when received from the same-sex parent. Partial correlational analyses revealed that the parenting-self-criticism relations remained significant when the mother's report of the child's early temperament was statistically controlled. The results also showed that for women, self-criticism was very stable from early adolescence to young adulthood. By contrast, there was no relation between self-criticism at ages 12 and 31 for men; however, there was a strong relation for men between age 12 self-criticism and inhibited aggressive impulses at age 31.     

Antidepressants in group psychotherapy

This article alerts us to consider depression as a relatively frequent cause of impasse in the course of group psychotherapy. The authors recommend the combined use of antidepressant medication along with group psychotherapy when such depression is confirmed independently outside the group. Common obstacles and pitfalls preventing successful combined treatment are reviewed; the depressive logjam is differentiated from common resistance; and profiles of responders versus nonresponders are described. A rationale of the combined treatment, its results, and implications for group therapists are all delineated.     

Processing of threat-related information in rape victims

We investigated selective processing of threat information in persons with posttraumatic stress disorder (PTSD) by using a modified Stroop procedure. Subjects were 15 rape victims with PTSD, 13 rape victims without the disorder, and 16 nontraumatized control subjects. They were asked to name the color of four types of words: specific threat (rape-related) words, general threat (related to physical harm and death) words, neutral words, and nonwords. Rape victims with PTSD evidenced a longer response latency for color naming of rape-related words than for other target-word types. Response latencies of non-PTSD victims and nonvictim control subjects did not differ across word types. Possible mechanisms underlying the selective processing of threat material are considered, and clinical implications are discussed.     

A theory of visual interpolation in object perception

We describe a new theory explaining the perception of partly occluded objects and illusory figures, from both static and kinematic information, in a unified framework. Three ideas guide our approach. First, perception of partly occluded objects, perception of illusory figures, and some other object perception phenomena derive from a single boundary interpolation process. These phenomena differ only in respects that are not part of the unit formation process, such as the depth placement of units formed. Second, unit formation from static and kinematic information can be treated in the same general framework. Third, spatial and spatiotemporal discontinuities in the boundaries of optically projected areas are fundamental to the unit formation process. Consistent with these ideas, we develop a detailed theory of unit formation that accounts for most cases of boundary perception in the absence of local physical specification. According to this theory, discontinuities in the first derivative of projected edges are initiating conditions for unit formation. A formal notion of relatability is defined, specifying which physically given edges leading into discontinuities can be connected to others by interpolated edges. Intuitively, relatability requires that two edges be connectable by a smooth, monotonic curve. The roots of the discontinuity and relatability notions in ecological constraints on object perception are discussed. Finally, we elaborate our approach by discussing related issues, some new phenomena, connections to other approaches, and issues for future research.     

Juvenile firesetting: a unique syndrome or an advanced level of antisocial behavior?

The current study examined whether juvenile firesetting represents a unique syndrome or an advanced level of antisocial behavior. Thirty-six incarcerated juvenile delinquents, all of whom met criteria for a diagnosis of Conduct Disorder, served as subjects and were categorized into one of three groups: firesetters, non-firesetters but comparable to firesetters in number of conduct disorder symptoms, and non-firesetters who displayed fewer conduct disorder symptoms than the other two groups. Caregivers completed the Child Behavior Checklist on the youth to provide information about the severity and range of psychopathology. The results indicated that firesetters and non-firesetters who had a comparable number of symptoms did not differ from one another on the CBCL subscales of adolescent psychopathology but both differed from the group with fewer symptoms. These results suggest that firesetting does represent an advanced level of antisocial behavior, but that firesetting is not a unique syndrome, at least not in terms of caretakers' perceptions of the youths' problematic behavior. Implications for treatment of firesetters are presented.     

Assertiveness, social support, and psychological adjustment following spinal cord injury.

Tested predictions that assertiveness and social support would be significantly predictive of psychological adjustment. Furthermore, it was anticipated that assertiveness and certain types of social relationships would differentially interact to predict adjustment, since positive and negative effects of both variables have been noted in prior research. Trained raters interviewed 156 persons receiving either in-patient or out-patient care for cord injuries and administered measures of assertiveness, social support, depression and psychosocial impairment. Persons who reported a keen sense of responsibility for the welfare of another reported more depression and impairment. Persons reporting higher levels of support facilitating social integration and reassuring personal worth were less depressed. Several significant interactions between assertiveness and different social support relationships revealed beneficial and deleterious effects on depressive behavior and impairment secondary to the disability. Results are discussed as they advance theoretical understanding of the effects of assertiveness and social support. Implications for discriminate cue learning in assertion training for persons with physical disability are proposed.     

Cognitive therapy. A 30-year retrospective

Several lines of investigation have evolved from the initial cognitive model of depression and other disorders. A large number of studies have tested the cognitive model using both clinical and laboratory-based strategies. In general, studies that most closely approximate the clinical conditions from which the theory was derived are supportive of the cognitive model of depression. Studies of anxiety and panic, although fewer, generally support the cognitive model of anxiety and panic. The application to the treatment of clinical problems has been promising and supports the concept of cognitive specificity. The cognitive therapy of depression has led to the utilization of specific cognitive strategies based on the specific conceptualizations of a given disorder to a wide variety of disorders. Study of abnormal reactions has also provided clues to the cognitive structure of normal reactions.
