Effects of intrahippocampal injections of the cholinergic neurotoxin AF64A on open-field activity and avoidance learning in the rat

The effects of direct intrahippocampal administration of the cholinergic neurotoxin, AF64A, were investigated in male rats. Bilateral injections of AF64A (5 nmole/2 microliters) produced a significant decrease in choline acetyltransferase (CAT) activity in the dorsal hippocampus (25%) and overlying frontoparietal cortex (30%) but no changes in the striatum. Rats lesioned with AF64A exhibited increased levels of open-field activity, which was most marked at 1 week after the lesion; however, the rates of intrasession habituation were similar in lesioned and control rats. Lesioned rats also displayed deficits in acquisition and retention of a passive avoidance task and less dramatic deficits in acquisition of two-way shuttle box avoidance. These findings indicate that lesioning of cholinergic terminals in the hippocampus and/or cerebral cortex with AF64A leads to long-term deficits in learning and memory as well as increases in open-field activity.     

Promoting safety belt use among state employees: the effects of prompting and a stimulus-control intervention.

This study assessed the effects of dashboard stickers and signature sheets on safety belt use among occupants of state-owned vehicles in three Florida agencies. The stickers and signature sheets contained information regarding a regulation requiring safety belt use and a consequence of a 25% reduction in benefits for noncompliance if the driver were to become involved in an accident. Safety belt use significantly increased during the intervention phase in all three agencies and maintained variable but high levels for 5 months. In Agency 1 and Agency 2 (stickers plus signature sheets) safety belt use increased from averages of 10.8% and 9.4% during baseline to 57.4% and 47.0%, respectively, during intervention. In Agency 3 (stickers only) the rates of safety belt use averaged 9.7% during baseline and 38.0% during intervention. Some increases in private vehicle use were observed. A substantial reduction in workers'' compensation claim costs was shown for the target agencies with some reductions also shown in the nontarget agencies.     

The right to effective behavioral treatment

WE PROPOSE THAT INDIVIDUALS WHO ARE RECIPIENTS OR POTENTIAL RECIPIENTS OF TREATMENT DESIGNED TO CHANGE THEIR BEHAVIOR HAVE THE RIGHT TO: (1) a therapeutic environment, (2) services whose overriding goal is personal welfare, (3) treatment by a competent behavior analyst, (4) programs that teach functional skills, (5) behavioral assessment and ongoing evaluation, and (6) the most effective treatment procedures available.     

PROMPTING PATRON SAFETY BELT USE AT A SUPERMARKET

We used a reversal (ABAB) design to assess the effects of a personal prompt on safety belt usage by grocery store patrons. A personal prompt delivered by grocery carriers resulted in a 12% increase in the number of patrons exiting the parking lot with their safety belts buckled. This simple, low-cost intervention offers potential savings to society from increased safety belt use.     

The scapegoat — or the one that got away

The scapegoat is the focus of projections. It may be an individual or a group, an obvious misfit or a concealed one, a temporary phenomenon or a permanent lifestyle (adopted willingly or unwillingly). The scapegoat makes it possible for man to live at peace with God, himself or his society by acting as symbolic recipient of qualities which man is unwilling to recognise in himself. The scapegoater by his treatment tries to reduce the scapegoat into something not human; for this reason a scapegoat which shows only small divergences from the norm evokes particular hostility. The individual scapegoat in a small group may accept his role fairly happily, but group scapegoats find few compensations. A variety of defence mechanisms will be adopted in these circumstances, but generally mature adjustment is impossible. The scientific and artistic achievements of scapegoats in the past have helped to liberalise society and extend the range of our compassion. So perhaps a society without scapegoats would lose its capacity for moral growth.     

CROSS-AGE TUTORING: FIFTH GRADERS AS ARITHMETIC TUTORS FOR KINDERGARTEN CHILDREN1

Five fifth-grade students tutored five kindergarten children in basic arithmetic skills for 7.5 weeks. A control group consisted of five kindergarten children who received no tutoring and were matched with the experimental group in arithmetic ability. Pre-, mid-, and posttesting was done using a skills-based arithmetic test. Results showed that the experimental group made far greater gains than the control group on a post-test comparison (matched pairs signed ranks test p = 0.062). In addition, a subanalysis of specific arithmetic skills showed they were improved only when tutoring for that skill was carried out. Systematic observations made of the tutor-student interactions indicated wide tutor-to-tutor variability in the percentage of student responses praised, and very little use of negative, disapproving statements. It was concluded that trained fifth-grade students can effectively teach basic arithmetic skills to kindergarteners.     

Today's women and depression

The author suggests that women in our society are more vulnerable to depression than ever before. A brief review of four psychoanalytical approaches to treatment and the religious care of the depressed woman are presented. The Book of Ruth is used as a case study of a woman's reactive depression.Her special interest and concentration are in the field of women's mental health. She has recently completed an Associate in Ministtry Degree from Southern Baptist Theological Seminary. Mrs. Bailey provides supervision for graduate students from Southern Seminary as well as Kent School of Social Work and University of Louisville Medical School. She is actively interested in pastoral care.     

Field-dependence, sensation-seeking, and preference of paintings

College students (122 males and 88 females) completed the Group Embedded Figures Test measure of field-dependence, and Sensation-Seeking Scale, and performed preference ratings on 40 slides of paintings. Factor analysis revealed six hypothesized and one unhypothesized preference dimensions that underlay preference ratings of paintings. It was hypothesized that the cognitive structuring ability associated with field-dependence would result in certain relationships between field-dependence and preference for paintings. Further, it was hypothesized that preference for novel, complex, and dynamic experiences, associated with sensation-seeking, would result in certain relationships between sensation-seeking and preference for paintings. For the full sample, three of five hypothesized relationships between field-dependence and preference for paintings were obtained, while three of four hypothesized relationships were found between sensation-seeking and preference for paintings.
