Traumatization of group leaders in their work with displaced persons

Displaced persons are a special, threatened group of people, participants in this war, who were suddenly forced to abandon their homes. The majority of them were, overnight, left without anything they had, some even without their closest family. They all have one thing in common: they have all lost so much. Work with such people is directed toward overcoming their feelings of loss and abandonment and preventing psychical decompensation. Groups of displaced persons temporarily sheltered in the Rijeka region have been observed to be markedly regressed, with increased sensitivity, a low degree of tolerance, great demands on society and strongly expressed projective tendencies. Therapists suffer personal traumatization in working with displaced persons. This paper describes the reactions and feelings of group leaders caused by manifestations of group dynamics in different phases of exile.     

西安市小学生中独生与非独生子女个性品质的比较研究

本文研究了西安城区１０所小学７８７名独生与非独生子女个性品质方面的情况。我们设计了有１８个行为项目的教师问卷（每项按五等评分）及家长问卷;对结果进行了因素分析,据所聚类的项目内容,将所得四个因素命名为人际关系、自我中心、学习动力和独立性,进行多变量的变异数分析结果表明,独生子女的自我中心和学习动力比非独生子女强烈;而独立性却比非独生子女差．这说明独生子女在个性品质方面既有缺点,也有优点,不能说得一无是处;关键在于正确的教育思想和方法。     

Effects of chronic ethanol consumption on gestation and lactation in rats

Chronic consumption of ethanol during pregnancy and lactation may lead to abnormalities in the fetus or infant. A group of female Wistar rats was submitted to ethanol treatment over a period of a month. A pair-fed control group received sucrose solution isocaloric to ethanol and the control group received water “ad libitum.” Afterward, the females were mated with males over a period of 20 days. At birth, each litter was maximized to eight pups and the remaining ones were decapitated to remove the fetal blood and brains. No significant difference was observed in fetal body and brain weight at birth. During lactation the ethanol and pair-fed groups gained less weight than the control group. After weaning, their weight became similar. Fetal blood glucose levels were decreased in the ethanol-treated group. One hundred percent of the pair-fed and control females delivered live fetuses at term and all survived; only 40% of the females in the ethanol group delivered, and one pup did not survive. Chronic ethanol treatment pointed to a possible reduction in the fertility. It seems likely that the change in body weight of ethanol-fed dams was caused by undernutrition.     

Children's perception of media-portrayed sex roles

The immediate impact on preschool and elementary school children of a televised presentation in which the traditional sex roles of physician and nurse were reversed was examined. After viewing a videotape of a male nurse and a female physician, subjects were asked to identify photographs or names of the physician and nurse. Preschool, first-, and fourth-grade children selected male names or pictures for the physician and female names or pictures for the nurse, thereby reversing genders. Their immediate recall appeared strongly influenced by their stereotypes rather than by the film they had just viewed. Seventh-grade children correctly identified the names of the physician and nurse.The authors wish to thank Dr. Edward F. Meydrech, Assistant Professor, Department of Preventive Medicine and Chief of the Division of Biostatistics, University of Mississippi Medical Center, for his invaluable assistance in the analysis of the data.

Evaluations of the Work of Men and Women as a Function of the Sex of the Judge and Type of Work

Forty-two male and 42 female subjects selected from a large city, a small town, or a university campus were asked to evaluate four pen and ink sketches and four quotations. Two sketches and two quotations were associated with fictitious women's names while the remainder were associated with fictitious men's names. A three-way interaction indicated that women tended to discriminate against the productions attributed to men, and men significantly discriminated against the productions of women. But all discriminations were limited to intellectual productions (quotations).     

Event-related brain potentials reflect traces of echoic memory in humans

In sequences of identical auditory stimuli, infrequent deviant stimuli elicit an event-related brain potential component called mismatch negativity (MMN). MMN is presumed to reflect the existence of a memory trace of the frequent stimulus at the moment of presentation of the infrequent stimulus. This hypothesis was tested by applying the recognition-masking paradigm of cognitive psychology. In this paradigm, a masking sound presented shortly before or after a test stimulus diminishes the recognition memory of this stimulus, the more so the shorter the interval between the test and masking stimuli. This interval was varied in the present study. It was found that the MMN amplitude strongly correlated with the subject’s ability to discriminate between frequent and infrequent stimuli. This result strongly suggests that MMN providesa measure for a trace of sensory memory, and further, that with MMN, this memory can be studied without performance-related distortions.     

ALTERING SHOPPERS' SUPERMARKET PURCHASES TO FIT NUTRITIONAL GUIDELINES: AN INTERACTIVE INFORMATION SYSTEM

This study reports the results of one effort to help supermarket shoppers alter food purchases to make purchases (and meals) that are lower in fat and higher in fiber. A prototype interactive information system using instructional video programs, feedback on purchases with specific goals for change, weekly programs, and the ability to track user interactions and intended purchases was evaluated. The major dependent measure was users' actual food purchases as derived from participants' highly detailed supermarket receipts. After a 5- to 7-week baseline phase, participants were randomly assigned to an experimental or control condition for the 7- to 8-week intervention phase. A follow-up phase began 5 to 8 weeks after participants completed the intervention and discontinued use of the system. The results indicated that experimental participants, when compared to control participants, decreased high fat purchases and increased high fiber purchases during intervention, with evidence for some maintenance of effect in follow-up. Plans for increasing the use and impact of the system are discussed.
