This study evaluated whether the relation between subjective memory complaints and cognitive performance is influenced by the presence of hypertension in the elderly. One hundred and five healthy older adults, 70–89 years of age, with and without hypertension treatment or diagnosis, completed a scale of subjective memory complaints. Participants were divided into those with mild memory concerns and those with minimal or no complaints. All participants completed a battery of neuropsychological tests including measures of verbal and nonverbal memory. After controlling for differences in age, gender, education, and overall intellectual ability, there were significant main effects for memory concerns and significant interactions for memory complaints and hypertension on several measures of memory performance. There were no main effects for hypertension on memory performance. Simple effects analyses of the interactions showed that the hypertensive complainers demonstrated poorer performance on measures of long-term memory and greater reliance on short-term recall than the hypertensive non-complainers. There were no differences in memory performance for the non-hypertensive groups. Among healthy elderly community-dwelling adults, those with mild subjective memory complaints in the context of hypertension demonstrated greater objective cognitive difficulties than those without hypertension as well as a greater reliance on a less efficient learning strategy. These findings suggest that memory concerns in the presence of hypertension may be important when evaluating treatment efficacy in these individuals and for identifying differences in cognitive aging.  相似文献

We evaluated the effects of an intraverbal training procedure on the acquisition, maintenance, and generalization of object‐substitution symbolic play in three 6‐year‐old Korean boys with autism spectrum disorder. A multiple probe across four behaviors design was used. All children acquired target symbolic play behavior, and novel responses emerged in training and follow‐up conditions. Generalization of object substitutions to untaught objects occurred in all three children. Free play observations indicated that symbolic play emerged in one child, and functional play increased in all three children.  相似文献

In view of the paucity of detailed followup studies on hyperactive children, the performance of 15 adolescents diagnosed hyperactive 5 years previously was compared to that of a control group of equivalent age, sex, intelligence, and social class. Eleven cognitive tests measuring sustained attention, visual-motor and motor skills, abstraction, and reading ability, as well as three self-assessment tests examining selfesteem, activity level, social functioning, academic status, and career aspirations were administered. The hyperactives performed significantly worse than the controls on the sustained attention, visualmotor, and motor tasks, and on two of the four reading tests. They also gave themselves significantly lower ratings on some of the selfesteem and sociability items. It would appear that the hyperactives at adolescence still have attentional and stimulus-processing difficulties, which affect not only their academic performance but also their social functioning.This study was supported by a Federal-Provincial Mental Health Grant to Dr. G. Weiss. The authors wish to thank Katherine Levine and Margaret Radigan for their assistance with test preparation and scoring. Thanks are also extended to Ken MacRae for his computer-processing advice, particularly his help with several multivariate and principal components analyses from which the present authors have derived their current theoretical position.

As researchers take advantage of advances in computer and related technologies, the amount of data has increased dramatically. Recent developments in database management systems (DBMS) such as client-server database technology provide the necessary tools for merging and managing data from various fields of study, as well as, various locations. This emerging technology allows the distribution of processing and data storage operations to a variety of computer plat-forms, thereby maximizing efficiency and flexibility. A DBMS that uses client-server technology is described.  相似文献

Research involving international research communities has been advocated in the field of behavior analysis (Dymond et al., 2000; Martin et al., 2016). The purpose of the present study was to report the status of behavioral research in mainland China, Hong Kong, and Taiwan, in terms of number of publications, types of research, and frequency of collaboration with international researchers. Fifteen behavioral journals were selected from the list by Cooper et al. (2020). These were searched by hand to find publications conducted in or authored by researchers from mainland China, Hong Kong, and Taiwan dating from each journal's inception to December 2021. The earliest publication we found appeared in 1980 in The Psychological Record. Over the following four decades (1980–1989; 1990–1999; 2000–2009; 2010–2021), the number of publications per decade increased dramatically and continues in recent years to rise. Publications include research reports, review papers, and conceptual articles, with the majority being basic research reports published in Behavioral Processes. Approximately half the publications involve collaboration with international researchers, mostly in North America. Implications for behavioral research, practice, and policy in mainland China, Hong Kong, and Taiwan are discussed.  相似文献

Across three studies, we identify an asymmetry between gift-givers’ and gift-recipients’ beliefs about the link between gift price and feelings of appreciation. Gift-givers expected a positive correlation between how much they spent on a gift and the extent to which gift-recipients would appreciate the gift because gift-givers assume that more expensive gifts convey a higher level of thoughtfulness. Gift-recipients, in contrast, reported no such association between gift price and their actual feelings of appreciation. This effect occurred regardless of whether the individual’s role and the magnitude of the gift were manipulated or measured in the field. Taken together, these findings cast doubt on whether gift-givers can draw on their personal experience as gift-recipients in order to identify meaningful gifts for others.  相似文献

During adolescence, cognitive abilities increase robustly. To search for possible related structural alterations of the cerebral cortex, we measured neuronal soma dimension (NSD = width times height), cortical thickness and neuronal densities in different types of neocortex in post-mortem brains of five 12-16 and five 17-24 year-olds (each 2F, 3M). Using a generalized mixed model analysis, mean normalized NSD comparing the age groups shows layer-specific change for layer 2 (p < .0001) and age-related differences between categorized type of cortex: primary/primary association cortex (BA 1, 3, 4, and 44) shows a generalized increase; higher-order regions (BA 9, 21, 39, and 45) also show increase in layers 2 and 5 but decrease in layers 3, 4, and 6 while limbic/orbital cortex (BA 23, 24, and 47) undergoes minor decrease (BA 1, 3, 4, and 44 vs. BA 9, 21, 39, and 45: p = .036 and BA 1, 3, 4, and 44 vs. BA 23, 24, and 47: p = .004). These data imply the operation of cortical layer- and type-specific processes of growth and regression adding new evidence that the human brain matures during adolescence not only functionally but also structurally.  相似文献

The nature and structure of well-being is a topic that has garnered increasing interest with the emergence of positive psychology. Limited research to date suggests two separate but related factors of subjective well-being and psychological well-being. Subjective well-being comprises an affective component of the balance between positive and negative affect, together with a cognitive component of judgments about one’s life satisfaction. Psychological well-being is conceptualised as having six components, including positive relations with others, autonomy, environmental mastery, self-acceptance, purpose in life and personal growth. In the current study, we used exploratory factor analysis and confirmatory factor analysis to examine the higher order factor structure of subjective and psychological well-being in a series of large UK samples. Analyses showed that subjective well-being and psychological well-being loaded separately onto two independent but related factors, consistent with previous research. Further, we demonstrated that these loadings did not vary according to gender, age or ethnicity, providing further support for the robustness of this higher order factor structure. The discussion locates these findings in context and explores future research directions on the associations between subjective and psychological well-being over time.  相似文献

Imitation of people on educational television is a potential way for very young children to learn new skills. Although toddlers in previous studies exhibited a “video deficit” in learning, 24-month-olds in Study 1 successfully reproduced behaviors modeled by a person who was on video as well as they did those modeled by a person who was present in the room (even after a 24-h delay). Neither displaced filming context nor cuts between actions affected toddlers’ imitation from video. Shortening the demonstration in Study 2 affected imitation in the video condition but not in the live condition. In Study 3, 24-month-olds who viewed the original longer videos on their family TV screens (with which they had a viewing history) imitated significantly less than those who viewed the videos on the laboratory monitor. Imitation of a live modeler was the same across settings (home or lab). Implications for toddlers’ judgments of reliable information sources and for the design of educational television programs are discussed.  相似文献

To date, developmental research has rarely addressed the notion that imitation serves an interpersonal, socially based function. The present research thus examined the role of social engagement on 24-month-olds' imitation by manipulating the social availability of the model. In Experiment 1, the children were more likely to imitate the exact actions of a live socially responsive model compared to a videotaped model who could not provide socially contingent feedback. In Experiment 2, the children were more likely to imitate the exact actions of a model with whom they could communicate via a closed-circuit TV system than a videotaped model who could not provide interactive feedback. This research provides clear evidence that children's imitative behavior is affected by the social nature of the model. These findings are discussed in relation to theories on imitation and the video deficit.  相似文献
