Sleep Loss and Temporal Memory

Historical evidence suggests that sleep deprivation affects temporal memory, but this has not been studied systematically. We explored the effects of 36 hr of sleep deprivation on a neuropsychological test of temporal memory. To promote optimal performance, the test was short, novel, and interesting, and caffeine was used to reduce 'sleepiness'. A total of 40 young adults were randomized into four groups: control + caffeine (Cc), control + placebo (Cp), sleep deprived + caffeine (SDc), and sleep deprived + placebo (SDp). Controls slept normally. Caffeine (350 mg) or placebo were given just prior to testing. The task comprised colour photographs of unknown faces and had two components: recognition memory (distinction between previously presented and novel faces), and recency discrimination (temporal memory), when a previously shown face was presented. An interpolated task, self-ordered pointing, acted as a distraction. Caffeine had no effects within control conditions, but significantly reduced subjective sleepiness in SDc. Recognition was unaffected by sleep deprivation, whereas for recency, sleep deprivation groups scored significantly lower than controls. There was no significant improvement of recency with caffeine in the SDc group. Both sleep deprivation groups had poorer insight into their performance with recency. Self-ordered pointing remained unchanged. In conclusion, sleep deprivation impairs temporal memory (i.e. recency) despite other conditions promoting optimal performance.     

Reaping the benefits of research: Technology transfer

This paper presents the results of a technology transfer project designed to transfer knowledge about model behavioral intervention projects that significantly decreased HIV-related risk behaviors. The National AIDS Demonstration Research Program Technology Transfer (NADR TT) Project encompassed: (1) preparation of manuals based on successful intervention research; (2) convening of 7 Regional meetings on Behavior Change Strategies for Injection Drug Users (IDUs); and (3) conduct of twenty-three state implementation training events. An evaluation of the NADR TT project showed that it was successful in its efforts to transfer knowledge regarding model intervention programs. Participants expressed an increased level of confidence in their ability to implement the model and individual model elements were perceived to be useful to—and implemented by—participants. Results also pointed out that significant barriers to implementation of model elements of the behavioral interventions exist.     

Theory of the invisible group applied to individual and group-as-a-whole interpretations

The theory of the Invisible Group explains the dynamics of groups in terms of four separate systems, hierarchically and isomorphically related, which enable the therapist to view group from four different perspectives and to interpret four different dimensions of group process. Person and member interpretations apply to aspects of the individual system; group-role and group-as-a-whole interpretations apply to aspects of the group system. Clinical examples illustrate how the psychotherapist can modify the dynamics of the group at the individual or at the group-as-a-whole level by modifying interpretations.     

Tri-ethnic alcohol use and religion,family, and gender

Nine different behavioral responses to alcohol by over two hundred ninth-graders in Austin, Texas, were examined in a survey designed to identify the relationship between adolescents' alcohol use, religious affiliation, religiosity, and gender. The relationship between alcohol use and family adaptability was also examined. While religious affiliation was found to be mildly predictive of use, religiosity determined only specific behavior. Gender differences in alcohol use appeared to be narrowing. Family adaptability was the most predictive variable, showing a relationship with six of the nine kinds of alcohol behavior. Future studies of family influences on adolescents' alcohol behavior and alcohol use among females are recommended.     

Marital group metaphors: Significance in the life stages of group development

Metaphorical content is abundant in the therapeutic process and has been noted and utilized in a variety of ways and settings by clinicians in the field. This paper focuses on metaphorical content in a marital therapy group and relates group metaphors to the life stages of group development. The co-authors illustrate the use of metaphors to assess the developmental stage of the group and to assist the therapist(s) in leading the group toward further growth and development. Figures are utilized to display the occurrence of metaphors by group stage, and a case example of a frequently stated group metaphor is offered to illustrate this process.     

Academic achievement among formerly homeless adolescents and their continuously housed peers

This study examined the school experiences and academic achievement of 46 adolescents in families who experienced homelessness and 87 permanently housed adolescents whose families received public assistance. Measures taken after the homeless students were rehoused showed that both groups valued school highly and were similar in cognitive abilities assessed with the similarities subtest of the Wechsler Intelligence Scale for Children—Revised (WISC-R). Formerly homeless students had more school mobility, more grade retention, and worse school experiences by mother report and lower plans for post-secondary education by self-report. Both groups scored poorly on standardized tests of academic achievement. Homelessness was associated with further declines in achievement during the period of maximal residential disruption, but did not have effects 5 years later.     

Exposure to child care,parenting style and attachment security

The present study addressed whether security of attachment is differentiated by quality of parenting and quantity of exposure to child care. Sixty mothers participated with their 14‐month‐old infants, who by the age of 12‐months had received either exclusive maternal care, or varying degrees of exposure to child care. Levels of attachment security were assessed through maternal completion of the Attachment Q‐Set(AQS); parenting quality was assessed through observations of mother–infant interactions during structured tasks. The scores that less sensitive mothers assign their toddlers is higher when their children are in child care for more hours per week; whereas the scores that more sensitive mothers assign their toddlers is lower when their children are in child care for more hours per week. These contrasting patterns suggest that the effects of parenting style on attachment security are moderated by quantity of exposure to child care. Copyright © 2003 John Wiley & Sons, Ltd.
