Gerontologists have long been concerned with the impact of individual-difference factors on memory. This study used a large sample (N = 2,495) of adult volunteers aged 18 to 90 years to determine if a set of individual-difference variables--vocabulary, education, depression, gender, marital status, and employment status--mediates the effects of aging on a wide range of laboratory-analogue tests of everyday memory. The data indicated that age was consistently the most significant predictor of memory performance, followed by vocabulary and gender. Vocabulary totally mediated age effects on a prose memory measure, and partial mediation of aging effects--primarily by vocabulary and gender--was observed on 5 other memory tests. These data suggest that when health samples of volunteers serve as research subjects, these individual differences can affect some memory test scores, but age remains the best overall predictor of memory performance. 相似文献

Short-term memory for actions was investigated for young adult and elderly adult subjects with the Brown-Peterson procedure at retention intervals of 0 and 15 s. The short-term memory trials were followed by the long-term recall of the prior to-be-remembered actions. The 15-s retention interval was filled either with no activity or with 1 of 3 different interfering activities. Verbal interference had little effect on short-term memory at either age level. Actions performed in the interval either by the subjects or by the experimenter produced significantly lower recall scores at each age level, with the decrement being more pronounced for the elderly than for the young subjects. The long-term memory results indicated that successful short-term recall enhanced later long-term recall, regardless of age level. 相似文献

This study investigated the relationship between intergenerational family relationships and Frankl's concept of meaning in life. Intergenerational family relationships were measured by the Personal Authority in the Family System Questionnaire (PAFS-QE) by Bray, Williamson, and Malone. The meaning in life variables were measured by the Life Attitude Profile-Revised (LAP-R) by Reker. This quantitative study, using the BMDP Statistical Package (Dixon, 1990), correlated the scores on various subscales from both instruments, resulting in seven statistically significant relationships. The findings, although modest, suggest the existence of a relationship between these two theoretical areas.This article is based in part on the first author's doctoral dissertation at Texas Woman's University.A copy of the PAFS-Q may be obtained from: James H.

The present study aimed to determine whether there was a systematic relationship between Rogers'(1957) core conditions of empathy, acceptance and genuineness, and counsellors' use of specific behaviours or skills which have been isolated for training. Video recordings of 12 counsellors' performance in 'naturalistic' counselling interactions were analysed. Counsellor, client and judges' ratings of the core conditions were obtained. Skill assessment included molar ratings of eight skill areas and molecular measures of 29 behaviours. The results indicated that there were few significant relationships. It is concluded that there is a discrepancy between specification of the skills or behaviours which are thought to communicate the core conditions and those which have been empirically demonstrated to do so. Implications for counsellor training and proposals for future research are discussed. 相似文献

Mental health professionals who lack medical training may also lack knowledge and understanding of the potential utility of medications in the treatment of emotional disturbance. They may also lack information regarding the effects and side-effects of medications which their clients may already be taking, or be uncertain when the nature of their client's situation suggests a psychiatric assessment regarding drug therapy. This paper offers an educational review in one such area: the pharmacological treatment of depression. It includes a brief review of theories regarding the aetiology of affective disorder, examines the methodes, mechanisms and efficacy of anti-depressants, and draws conclusions regarding the appropriate use of pharmacological treatment. 相似文献

Simultaneous prompting (a type of antecedent prompt and test procedure) and constant time delay were compared with four students with moderate mental retardation learning expressive sight words. A parallel treatments design across word sets and replicated across students was used. For acquisition, the simultaneous prompting procedures required fewer trials, sessions, and training time to criterion and resulted in fewer student errors during daily probe and training sessions. However, maintenance data indicated mixed results across the two procedures. Reliability data (both dependent and independent variables) revealed no differences between the two procedures in terms of the teacher's accuracy in recording student responses and implementing each procedure. Future research issues are discussed. 相似文献

Twenty years ago, William Kessen, Greta Fein and I developed and tested a model of parent education, a model which involved variation in curricular content, didactic approaches, and child outcomes–experimentally contrasted. Our experience yielded some valuable lessons about the extent to which researchers can influence parents' behaviour, and parents their children's development. In the present article I suggest that these lessons might be useful for researchers now as they were for us then. I present some observations about the research that developmental psychologists have done in the intervening two decades and suggest that we could learn much by using such a model of parent education to answer questions about the effets of parents' behaviour on children's development. Carefully done, parent education studies can yield valuable information about many of the questions raised in recent correlational research. Parent training research can suggest hypotheses that can be tested with data collected non-interventively and analysed in causal model analyses–and vice versa. What is more, because one reason for studying parent effects is so that we can offer guidance to parents about rearing their children, this design has a particular advantage; it is both the medium and the message. 相似文献
