Observations of aggressive children during peer provocation and with a best friend

Observational methods were used to examine aggressive children's peer relations in 2 contexts: when being teased by a peer and when interacting with a best friend. Because aggressive children may have more difficulty than nonaggressive children in both peer contexts, the authors also examined whether relations between behaviors across contexts varied as a function of aggression. Results indicated that aggression was related to children's behavior when provoked. Children's behavior when provoked was associated with fewer positive and more negative interactions with their best friend, particularly for aggressive children. Results are discussed with respect to social norms in middle childhood and informing interventions for aggressive children.     

Hippocampal inactivation enhances taste learning

Learning tasks are typically thought to be either hippocampal-dependent (impaired by hippocampal lesions) or hippocampal-independent (indifferent to hippocampal lesions). Here, we show that conditioned taste aversion (CTA) learning fits into neither of these categories. Rats were trained to avoid two taste stimuli, one novel and one familiar. Muscimol infused through surgically implanted intracranial cannulae temporarily inactivated the dorsal hippocampus during familiarization, subsequent CTA training, or both. As shown previously, hippocampal inactivation during familiarization enhanced the effect of that familiarization on learning (i.e., hippocampal inactivation enhanced latent inhibition of CTA); more novel and surprising, however, was the finding that hippocampal inactivation during training sessions strongly enhanced CTA learning itself. These phenomena were not caused by specific aspects of our infusion technique--muscimol infusions into the hippocampus during familiarization sessions did not cause CTAs, muscimol infusions into gustatory cortex caused the expected attenuation of CTA, and hippocampal inactivation caused the expected attenuation of spatial learning. Thus, we suggest that hippocampal memory processes interfere with the specific learning mechanisms underlying CTA, and more generally that multiple memory systems do not operate independently.     

Effects of gender and situation on the perception of sexual harassment

This study addressed three sources of variability in the perception of sexual harassment: the gender of the observer, the gender combination of the harasser and victim, and the role relationship between the harasser and victim. College students (N = 197), approximately 80% of whom were Caucasian, single, and in their early 20s, were randomly divided into two groups. In one group, the harasser was a man and the victim was a woman. In the other group, the harasser was a woman and the victim was a man. Participants rated the degree to which they thought sexual harassment occurred in 20 hypothetical interactions in each of three situations using a 7-point sexual harassment scale. Men and women rated the situations alike as long as the harasser was a man and the victim was a woman. When the perpetrator was a woman and the victim was a man, men gave significantly lower ratings than women. In contrast, women's ratings were the same regardless of the gender of the harasser. Harassment ratings also varied as a function of the power differential between the harasser and victim. The more egalitarian the relationship, the less likely participants were to perceive the behavior as sexually harassing.     

DISSOCIATION OF STORAGE AND REHEARSAL IN VERBAL WORKING MEMORY:

Abstract— Current cognitive models of verbal working memory include two components a phonological store and a rehearsal mechanism that refreshes the contents of this store We present research using positron emission tomography (PET) to provide further evidence for this functional division In Experiment I, subjects performed a variant of Sternberg's (1966) item recognition task Experiment 2 used a continuous memory task with control conditions designed to separate the brain regions underlying storage and rehearsal The results show that independent brain regions mediate storage and rehearsal In Experiment 3, a dual-task procedure supported the assumption that these memory tasks elicited a rehearsal strategy     

COGNITIVE PROFILES OF READING-DISABLED CHILDREN:

Abstract— A comprehensive cognitive appraisal of elementary school children with learning disabilities showed that within the language sphere, deficits associated with reading disability are selective. Phonological deficits consistently accompany reading problems whether they occur in relatively pure form or in the presence of coexisting attention deficit or arithmetic disability. Although reading-disabled children were also deficient in production of morphologically related forms, this difficulty stemmed in large part from the same weakness in the phonological component that underlies reading disability. In contrast, tests of syntactic knowledge did not distinguish reading-disabled children from those with other cognitive disabilities, nor from normal children after covarying for intelligence.     

The variance of the number of mutual choices in sociometry

The variance of the number of mutual dyads in a sociometric situation where each member of a group chooses independently and at random is derived for unrestricted numbers of choices per group member, as well as for a fixed number of choices. The distribution of the number of mutuals is considered.We are indebted to Robert Bush and Hartley Rodgers of Harvard University for helpful criticisms.     

Cost-effectiveness of providing insurance benefits for posthospital psychiatric halfway house stays

A model insurance benefit package of post hospitalization psychiatric halfway house care was developed and administered to 32 hospitalized mentally ill persons. The therapeutic and cost effectiveness of providing a 120-day benefit package was examined over a 14-month post-hospitalization period. This was compared with the effectiveness of hospitalization benefits alone for the same patients over the 42 months prior to halfway house admission. In terms of therapeutic efficacy, there was no significant deterioration after hospitalization release in either the symptom or behavioral coping scales, except for an increase in somatization. Yearly hospital recidivism rates fell from 79% to 29%, and the average yearly length of hospital stay per patient fell from 83 days to 18 days. In terms of cost-effectiveness, halfway house benefits saved the insurers 59% of their hospitalization costs. The implications of these findings are discussed.     

The patient-analyst match and the outcome of psychoanalysis: a pilot study

This paper presents a pilot study in which we explore the possibility that the match between analyst and analysand is a factor of central importance in the analytic situation. It is an attempt to look at the issue of match across a large number of patients. The data we used were not collected for studying this topic; thus, the study has serious limitations. Nevertheless, certain patterns emerged which support our thesis that patient-analyst match plays a significant role in the outcome of psychoanalysis. We present this work as a first step in developing concepts and methods which will be pursued in a more systematic and rigorous fashion in a later study.
