Transfer of responses to open and closed shapes in discrimination learning by cats

Two sets of 32 cats each were matched for performance in learning to discriminate an open and a closed shape and were then trained on a transfer task. The consistent groups were rewarded for choosing the same class of shape (open or closed) in learning and transfer. The inconsistent groups were rewarded for choosing the open figure in one task and the closed figure in the second, or vice versa. After learning the transfer task, all of the Ss relearned the original discrimination task under the same conditions that prevailed in initial training. The inconsistent groups made more errors on both the transfer and retention problems; both these differences were significant at the 0.1% level of confidence. These results and those obtained on preference tests support the hypothesis that cats classify shapes as open or closed in terms of perimeter and number of sides.     

Mood, personality disorder symptoms and disability in obsessive compulsive hoarders: a comparison with clinical and nonclinical controls

Hoarding is a symptom of obsessive compulsive disorder (OCD), as well as a diagnostic criterion for obsessive compulsive personality disorder (OCPD). One recent study suggests that people who suffer from compulsive hoarding report more general psychopathology than people who do not [Frost, R.O., Krause, M.S., & Steketee, G. (1996). Hoarding and obsessive compulsive symptoms. Behavior Modification, 20, 116-132]. The present study addressed whether persons with OCD hoarding exhibit more depression, anxiety, OCD and personality disorders symptoms than community controls, OCD nonhoarders, or other anxiety disorder patients. Disability was also examined. Hoarding subjects were older than the other three groups, but age did not account for any of the differences observed among the groups. Compared to controls, OCD hoarding, nonhoarding OCD and anxiety disorder patients showed elevated YBOCS scores, as well as higher scores on depression, anxiety, family and social disability. Compared to nonhoarding OCD and anxiety disorder patients, OCD hoarding patients scored higher on anxiety, depression, family and social disability. Hoarding subjects had greater personality disorder symptoms than controls. However, OCD hoarding subjects differed from OCD nonhoarding and anxiety disorder subjects only on dependent and schizotypal personality disorder symptoms. The findings suggest that hoarding is associated with significant comorbidity and impairment compared to nonhoarding OCD and other anxiety disorders.     

Contemporary views of man in psychology

Summary Contemporary views of man in psychology are in flux. The American tradition of experimental materialism is being modified by serious attention to personality theory. The existential movement in Europe is beginning to have a serious influence on both theory and therapy. The development of psychosomatic medicine is part of a vital reconsideration of the problems of mind-body. And within the psychotherapeutic disciplines, serious attention is being given to the role of patient-therapist values and the therapeutic concept of man. The relevance of spiritual concepts is being given serious consideration, and potential modifications of theology and psychology are being entertained by both disciplines. Hopefully, out of this interchange will develop more adequate concepts of man and God.Presented at Eastern Mennonite College and Seminary, January, 15, 1965, as one of the 1964–65 lecture series on Contemporary Views of Man.     

Psychiatry and religion circa 1978: Analysis of a decade,part II

Prior tensions between science and religion have dissolved and coalesced into new alliances based on ideology and philosophy. This general cultural pattern is reflected in the realignment of interests and interactions between paychiatry and religion. There are increasing numbers of mental health professionals with devout religious commitments and involvement in religiously oriented mental health activities; while clergy have developed new organizational structures to reflect many diverse mental health interests, including pastoral counseling, community mental health chaplains, hospitals chaplains, and expanded parish ministries. Clinical and research literature has continued to rapidly proliferate, while a unique genre of pastoral care and counseling literature has emerged. A decade ago there was hope for an amicable alliance between specialists in psychiatry and in religion. That irenic quest has shifted into overlapping goals and roles, with tensions between those engaged in universalistic norms and those seeking to develop particularistic norms.Dr. Pattison is Director of Training, Orange County Department of Mental Health and Professor and Acting Chairman of the Department of Psychiatry and Human Behavior, University of California Irvine Medical Center, 101 City Drive South, Orange, California 92668.

Is there a ‘psychosomatogenic’ family?*

Review of the literature revealed two family theories of psychosomatic illness: the ‘enmeshed’ family of Minuchin and the family with affect disturbances. We interviewed twelve families, each containing a child with eczema. Most, but not all, of the families do fit in with one or other or both of the proposed interactional patterns, but the theory of a single family type, the ‘psychosomatogenic family’, is not supported. This complements the studies of individuals where specificity hypotheses have proved oversimplified.     

A revision of the definition of lying as an untruth told with intent to deceive

The traditional and prevailing definition of lying is that lying is some variation or combination of: an untruth told with intent to deceive. I establish that this is the case, and that, as a result, contradictions and injustices arise. An alternative definition is proposed which is shown to avoid these difficulties. It is also shown that and how on the new definition the alleged Liar paradox is easily dissolved.     

How do I appear to others? Social anxiety and processing of the observable self

Two information processing biases that could maintain social anxiety were investigated. High and low socially anxious individuals encoded positive and negative trait words in one of three ways: public self-referent, private self-referent, and other-referent. Half were then told they would soon have to give a speech. As predicted, compared to low socially anxious individuals, high socially anxious individuals recalled less positive public self-referent words, but only when both groups were anticipating giving a speech. No memory biases were observed for private self-referent or other-referent words. Next all participants gave a speech. Correlational analyses suggested that high socially anxious individuals may use the somatic concomitants of anxiety to overestimate how anxious they appear and underestimate how well they come across.     

Perception of translational heading from optical flow

Radial patterns of optical flow produced by observer translation could be used to perceive the direction of self-movement during locomotion, and a number of formal analyses of such patterns have recently appeared. However, there is comparatively little empirical research on the perception of heading from optical flow, and what data there are indicate surprisingly poor performance, with heading errors on the order of 5 degrees-10 degrees. We examined heading judgments during translation parallel, perpendicular, and at oblique angles to a random-dot plane, varying observer speed and dot density. Using a discrimination task, we found that heading accuracy improved by an order of magnitude, with 75%-correct thresholds of 0.66 degrees in the highest speed and density condition and 1.2 degrees generally. Performance remained high with displays of 63-10 dots, but it dropped significantly with only 2 dots; there was no consistent speed effect and no effect of angle of approach to the surface. The results are inconsistent with theories based on the local focus of outflow, local motion parallax, multiple fixations, differential motion parallax, and the local maximum of divergence. But they are consistent with Gibson's (1950) original global radial outflow hypothesis for perception of heading during translation.
