The etiology of schizophrenia as perceived by psychiatrists in Europe and the United States

This paper compares and contrasts statements made by American and European psychiatrists on the etiology of schizophrenia. In the U.S., leading figures in psychiatry hold increasingly to the view that the disorder is physiogenic at source—from which it seems to follow that the appropriate treatments should similarly focus on physiological and pharmacological therapies. In contrast, European psychiatrists seem to be divided in support for organic and psychodynamic explanations. Some European writers have pointedly warned against over-interpreting recent studies which seem to point to specific organic dysfunctions and deficits as schizophrenogenic. This paper was presented at the Second Annual Convention of the American Psychological Society, Dallas, Texas, June 7–10, 1990.     

Differences in Personality Disorders and Family-of-Origin Characteristics for Male and Female Alcoholics: Implications for Treatment

This study investigated the personality and family-of-origin differences in male and female alcoholics. Results indicated that, regarding personality, men (both type 1 and type 2) were less troubled than were women. Implications for treatment based on these results are included.     

Ninety-three pictures and 108 questions for the elicitation of homophones

Homographs and homophones have interesting linguistic properties that make them useful in many experiments involving language. To assist researchers in the elicitation of homophones, this paper presents a set of 93 line-drawn pictures of objects with homophonic names and a set of 108 questions with homophonic answers. Statistics are also included for each picture and question: Picture statistics include name-agreement percentages, dominance, and frequency statistics of depicted referents, and picture-naming latencies both with and without study of the picture names. For questions, statistics include answer-agreement percentages, difficulty ratings, dominance, frequency statistics, and naming latencies for 60 of the most consistently answered questions.     

The perception of shape and curvedness from binocular stereopsis and structure from motion

The integration of binocular stereopsis and kinetic depth was measured for two distinct aspects of 3-Dstructure: (1)shape index, which is a measure of scale-independent structure, and (2)curvedness, which is a measure of scale-dependent structure. We found that motion contributes significantly more to judged shape index than it does to judged curvedness, and stereo contributes significantly more to judged curvedness than it does to judged shape index. This suggests that the differences in the relative contribution of motion and stereo reported here occurred because these two sources do not equally specify the scale-dependent and scale-independent aspects of surface structure. Furthermore, these results seem to be inconsistent with integration models in which the different visual cues all initially contribute to the same single representation of 3-Dstructure.     

Assessing Hypersensitive Narcissism: A Reexamination of Murray''s Narcism Scale

A new measure of hypersensitive narcissism was derived by correlating the items of H. A. Murray's (1938) Narcism Scale with an MMPI-based composite measure of covert narcissism. In three samples of college students (totalN= 403), 10 items formed a reliable measure: the Hypersensitive Narcissism Scale (HSNS). The new HSNS and the MMPI-based composite showed similar patterns of correlations with the Big Five Inventory, and both measures correlated near zero with the Narcissistic Personality Inventory, which assesses overt narcissism. Results support P. Wink's (1991) distinction between covert and overt narcissistic tendencies in the normal range of individual differences and suggest that it would be beneficial for personality researchers to measure both types of narcissism in future studies.     

Perceiving geographical slant

People judged the inclination of hills viewed either out-of-doors or in a computer-simulated virtual environment. Angle judgments were obtained by having people (1) provide verbal estimates, (2) adjust a representation of the hill’s cross-section, and (3) adjust a tilt board with their unseen hand. Geographical slant was greatly overestimated according to the first two measures, but not the third. Apparent slant judgments conformed to ratio scales, thereby enhancing sensitivity to the small inclines that must actually be traversed in everyday experience. It is proposed that the perceived exaggeration of geographical slant preserves the relationship between distal inclination and people’s behavioral potential. Hills are harder to traverse as people become tired; hence, apparent slant increased with fatigue. Visually guided actions must be accommodated to the actual distal properties of the environment; consequently, the tilt board adjustments did not reflect apparent slant overestimations, nor were they influenced by fatigue. Consistent with the fact that steep hills are more difficult to descend than to ascend, these hills appeared steeper when viewed from the top.     

The advantage of first mention in Spanish

An advantage of first mention—that is, faster access to participants mentioned first in a sentence—has previously been demonstrated only in English. We report three experiments demonstrating that the advantage of first mention occurs also in Spanish sentences, regardless of whether the first-mentioned participants are syntactic subjects, and regardless, too, of whether they are proper names or inanimate objects. Because greater word-order flexibility is allowed in Spanish than in English (e.g., nonpassive object-verb-subject constructions exist in Spanish), these findings provide additional evidence that the advantage of first mention is a general cognitive phenomenon.     

Children's capacity to agree to psychological research: knowledge of risks and benefits and voluntariness

A series of studies investigated the capacity of children between the ages of 7 and 12 to give free and informed consent to participation in psychological research. Children were reasonably accurate in describing the purpose of studies, but many did not understand the possible benefits or especially the possible risks of participating. In several studies children's consent was not affected by the knowledge that their parents had given their permission or by the parents saying that they would not be upset if the children refused. In contrast, other studies found that children were much more likely to stop their participation if the experimenter said explicitly that she would not be upset if they stopped. We suggest that experimenters should pay more attention to describing the possible risks and benefits of participation in research, and that they should also make it clearer to children that they are free to stop once they have begun.     

IMPLICIT MEMORY IN AMNESIC PATIENTS:

Abstract— Previous observations of spared priming in amnesic patients have been based almost entirely on data from visual implicit memory tests Our research examined perceptual priming.in amnesic patients and control subjects on an auditory identification task in which previously spoken words and new words were presented in white noise We manipulated type of encoding task (semantic vs nonsemantic) and speaker's voice at study and test (same vs different) Priming was little affected.by either manipulation, and amnesic patients exhibited normal priming in all experimental conditions On an explicit test of recognition memory, by contrast, amnesic patients exhibited.severely impaired performance following the semantic study task, all subjects showed poor explicit memory following the nonsemantic study task Results are consistent with the idea that auditory priming depends largely on a presemantic auditory perceptual representation system
