Logical reasoning deficits in schizophrenia and brain damage.

Von Domarus and Arieti have theorized that failure to reason by conventional logical rules is at the root of schizophrenic thought disorder, but the available research on this view is inconclusive. We compared the performance of schizophrenics (N = 100), brain-damaged patients (N = 50) and psychiatric controls (N = 50) on closely matched measures of Overexpansive and "Von Domarus" (similarity implies identity) syllogistic reasoning errors. Before the samples were matched for education and intelligence, the brain-damaged and schizophrenic patients made more Overexpansive errors than the controls, but the Von Domarus error difference was not significant. After matching, both differences were nonsignificant. The results indicate that inability to use syllogistic reasoning properly is probably not the root cause of schizophrenic thought disorder.

Depressive realism: effects of depression severity and interpretation time.

This study examined the theory of depressive realism, which posits that depressed people often are more accurate in perceptions and judgments than nondepressed people. Two possible qualifications to this theory were examined: (1) severity of depression moderates the effect, and (2) length of processing time will impact the presence of bias in depressed people, that is, negative bias will develop over time. College students were presented with a bogus personality profile that actually consisted of items previously rated as neutral in desirability. Participants rated these profiles for desirability initially and then again three days later. Results indicated a significant effect of depression severity on desirability rating. Nondepressed and mildly depressed students found their profiles to be more positive than the moderately/severely depressed students, with both groups having scores in the positive range. However, those participants who were moderately/severely depressed showed a negative bias in their ratings. No support was found for the effect of different times of interpretation.

Distorting reality for children: body size proportions of Barbie and Ken dolls.

Using hip measurements as a constant, calculations were made to determine the changes necessary for a young, healthy adult woman and man to attain the same body proportions as Barbie and Ken dolls, respectively. Among the changes necessary were for the female to increase 24 in. in height, 5 in. in the chest, and 3.2 in. in neck length, while decreasing 6 in. in the waist, and for the male to increase 20 in. in height, 11 in. in the chest, and 7.9 in. in neck circumference. Like adults, children are exposed to highly unrealistic ideals for shape and weight.

Longitudinal assessment of symptom and subtype categories in obsessive-compulsive disorder.

Although it has been postulated that symptom subtypes are potential predictors of treatment response, few data exist on the longitudinal course of symptom and subtype categories in obsessive-compulsive disorder (OCD). Putative subtypes of OCD have gradually gained more recognition, but as yet there is no generally accepted subtype discrimination. Subtypes, it has been suggested, could perhaps be discriminated based on autogenous versus reactive obsessions stemming from different cognitive processes. In this study, our aim was to assess whether symptom and subtype categories change over time. Using the Yale-Brown Obsessive Compulsive Symptom Checklist (Y-BOCS-SC), we assessed 109 patients who met DSM-IV criteria for OCD to establish baseline values, then reassessed 91 (83%) of the initial group after 36+/-8.2 months. Upon reassessment, we found significant changes from baseline within aggressive, contamination, religious, symmetry and miscellaneous obsessions and within checking, washing, repeating, counting and ordering compulsion categories. Sexual, hoarding, and somatic obsessions, and hoarding and miscellaneous compulsions, did not change significantly. In accordance with the relevant literature, we also assigned patients to one of three subtypes--autogenous, reactive, or mixed groups. Though some changes in subtype categories were found, no subtype shifts (e.g., autogenous to reactive or reactive to autogenous) were observed during the course of the study. Significantly more patients in the autogenous group did not meet OCD criteria at follow-up than did patients in the other groups. Our results suggest that the discrimination between these two types of obsession might be highly valid, because autogenous and reactive obsessions are quite different, both in the development and maintenance of their cognitive mechanisms, and in their outcome.

Identity: recent findings and clinical implications.

After a review of foundational contributions to the concept of identity, including Erikson's, the author discusses the research methods and findings of the Personality Disorders Institute of the Joan and Sanford I. Weill Medical College of Cornell University regarding the concepts of normal identity and identity diffusion, toward an elucidation of the psychopathology of personality disorders--their etiology, diagnosis, and treatment. The application of an object relations theory model to analyze the development of identity clarifies the relationship of individual identity with the social and cultural frame that influences identity formation and may amplify the effects of pathological identity development. Detailed excerpts are presented from a diagnostic structural interview at the Personality Disorders Institute.

Individualized measurement of irrational beliefs in remitted depressives.

Recent reviews of cognitive theories of depression have noted that individualized assessment strategies might help to resolve mixed findings regarding the stability of depressotypic beliefs and attitudes. We describe encouraging results for an individualized measure of one such cognitive construct, irrational beliefs. Twenty depression-prone women (recurrent major depressives in full remission) and twenty closely matched never-depressed controls completed leading forced-choice measures of irrational beliefs (the Belief Scale; BS) and sociotropy-autonomy (The Revised Personal Style Inventory), as well as the Specific Demands on Self Scale (SDS). The BS requires participants to rate their agreement with twenty preselected statements of irrational beliefs, while the SDS focuses on whether participants harbor any strongly held irrational beliefs, even if uncommon or idiosyncratic. Consistent with previous research, there were no group differences on the traditional measure of irrational beliefs. In contrast, depression-prone participants strongly exceeded controls on the SDS, and this difference persisted after controlling for residual depression, anxiety symptoms, anxiety diagnoses, sociotropy, and autonomy. These findings provide some initial support for a key assumption of the rational-emotive model of depression, and, more broadly, suggest that individualized assessment strategies may help researchers capture the core negative beliefs of asymptomatic individuals, even in the absence of mood or cognitive priming.

Coping strategies for visual hallucinations in Parkinson's disease.

We assessed the use of coping strategies in Parkinson's disease patients with visual hallucinations, using a semi-structured questionnaire. We found that 36 of our 46 Parkinson's disease subjects with hallucinations (78%) used coping strategies: cognitive techniques in 69%; interactive techniques in 62%; and visual techniques in 33%.

Steps toward healing: false memories and traumagenic amnesia may coexist in vulnerable populations.

Child abuse is surely the most agonizing psychological issue of our time. We decry the tendency to polarize around the either-or dichotomy of "recovered versus false memories," when both are likely to occur. Memory researchers seem to generalize from the mild, one-shot stressors of the laboratory to the severe repeated traumas reported by abused populations, an inferential leap that is scientifically dubious. Naturalistic studies show (a) some post-traumatic memory impairment (not just forgetting, but difficulty remembering in spite of repeated efforts); (b) dissociativity, such as emotional numbing, detachment, and the like; but also (c) increased suggestibility (Spiegel & Cardena, 1991). About 20% of the normal population is highly suggestible, and in these individuals it is trivially easy to show suggested amnesia, detachment, perceptual blocking, etc., as well as to suggest dramatically false memories. It is therefore vital to assess suggestibility and dissociativity in traumatized populations. Adult survivors of abuse may show both more false "memories" and more "false forgetting" than the normal population.

Metamemory and memory construction.

In this article, we present the contemporary conceptualization of metamemory as beliefs, accurate and naive, about memory. We discuss the implications of metamemory for memory construction in general and for suggestibility and the recovery of memories in particular. We argue that beliefs about memory influence (a) the probability that suggestions will be incorporated into memory and (b) judgments about the veracity of subsequent recollections. Implications for research on the role of beliefs in suggestibility and memory recovery are outlined.
