Younger and older adults were compared on new tests for item and temporal memory suitable for use in future electrophysiological or neuroimaging studies. Following a series of 10 simple line drawings, 4-choice panels containing two previously seen targets and two novel distractors appeared. Participants identified which pictures had been seen previously (item), or which of the items was presented earliest (temporal order). Performance of younger adults was superior to that of older adults. Memory for item and temporal order were equivalent in the younger group. In contrast, the item memory of the older group was superior to memory for temporal order, confirming previous evidence of differential impairment of memory for temporal order with age. 相似文献

Rodent studies demonstrate parallel age-related changes in spatial memory and the hippocampal formation. Converging cognitive, neuropsychological, and neurobiological evidence suggests similar changes in humans, although these correlates have not been studied in the same individuals. The purpose of the current project was to develop and validate a human analog of a rodent spatial memory task for future use in correlative studies of spatial memory and brain structure and function. Younger and older healthy adults studied the location of a target relative to distal cues in a large tent-like enclosure. Group performances were similar for the practice trial, which could be solved verbally, suggesting similar abilities to remember the configuration of multiple stimuli in a large space. However, on subsequent trials, which depended more upon spatial memory, older adults were impaired relative to their younger counterparts. 相似文献

This study examined possible effects of aging on the lateralization of stimulus-evoked emotional facial muscle activity. Older participants (mean age 68.4 years) and younger participants (mean age 26.4 years) viewed slides of positive, neutral, or negative emotional content. While participants viewed the slides, bilateral electromyographic (EMG) recordings were obtained from the skin surface over zygomatic and corrugator facial muscles. The participants also made ratings of experienced emotional valence and arousal. Expected patterns of subjective experience and asymmetrical EMG activity were found in response to target stimuli. Greater corrugator muscle activity occurred during presentation of negative stimuli, whereas greater zygomatic muscle activity occurred during presentation of positive stimuli. Consistent with right-hemisphere specialization theories of emotion, left-sided facial EMG activity was consistently greater than that of the right side during presentation of emotional stimuli. However, neither subjective ratings nor EMG patterns showed a significant effect of age group. Such similar patterns of emotional response for the two groups suggest, that the aging process does not produce marked changes in stimulus-evoked emotional experience or in the pattern, magnitude, or lateralization of facial muscle activity associated with emotional states. 相似文献

This study investigated the relationships among leisure, social self image, peer pressure and at-risk behaviours of adolescents in Nigeria. It also examined the moderating roles of gender, age, and locale and school type on measured relationships. A total of 1,141 adolescents with a mean age of 16 participated in the study. The results revealed significant relationships among leisure, social self-image, peer pressure and involvement in at-risk behaviours. Leisure was found to be greatest predictor of at-risk behaviours. The variable of gender stood out as a significant moderator of the relationships between leisure, social self-image, peer pressure and at-risk behaviours, while school type moderated only the relationship between leisure and at-risk behaviours. 相似文献

Little is known about attitudes of parents of Sickle Cell Anemia patients in sub-Saharan Africa regarding prenatal genetic
diagnosis and termination of an affected pregnancy. In this study, structured face-to-face interviews were conducted with
a sample of 130 parents in Cameroon that had at least one living child with Sickle Cell Anemia. The majority of participants
lived in urban areas (89%), were female (80%), Christian (93%), married (60.2%) in monogamous households (81.1%), were employed
(61.7%), and had at least a secondary or tertiary education (82%). The majority of parents accepted the principle of prenatal
genetic diagnosis for Sickle Cell Anemia (89.8%) and termination of pregnancy (62.5%). Acceptance of the principle of pregnancy
termination increased with unemployment (p < .01) and single marital status (p < .05). The results of this study suggest Cameroonian parents with children affected with Sickle Cell Anemia generally accept
the principles of prenatal diagnosis and in some cases termination of a pregnancy affected with Sickle Cell Anemia. Additional
findings, policy and practice implications, and research recommendations are presented. 相似文献

Using the example of a voiding cystourethrogram (VCUG), a painful radiological procedure, this study investigated whether
parental soothing behavior (reassuring comments like “it’s almost over” or “You’re O.K.” and soothing by “sh, sh”) in one
phase of the procedure influenced the child’s distress in the following phase. The sample was comprised of 68 2–8 year-old
children and the accompanying parent(s). Child and parental behavior during the VCUG was coded using a standardized rating
scale (CAMPIS-R). Parental reassurance during the anticipatory phase significantly increased the child’s distress of the following
phase, while parental “sh, sh” significantly reduced it. Both parental behaviors showed no significant effect on the child’s
distress of the following phase when applied during the procedure itself. Results underline the importance of differentiating
between anticipatory and procedural phases of the VCUG. Counselling methods for parents on more appropriate strategies to
assist their children during procedural phases of the VCUG are necessary. 相似文献
