In Experiment 1, groups of Korsakoff amnesics and alcoholic controls learned a list of paired-associate words in a standard testing room or in a room with distinctive contextual features. Recall was tested 48 hr later in the same or other context. This procedure was repeated in Experiment 2 with old people living in institutions or in the community, but matched for age, health, education, and socioeconomic background. The amnesic patients and institutionalized old people, relative to their comparison groups, were more impaired in recalling the lists under standard conditions and were more responsive to contextual cuing, especially when the distinctive cues were provided during original learning. The results highlight the susceptibility to interference of Korsakoff amnesics and institutionalized old people and offer further evidence that both groups are more responsive to salient contextual cues than either young people or old people living in the community.  相似文献

We tested the capacity to perceive visual expressions of emotion, and to use those expressions as guides to social decisions, in three groups of 8‐ to 10‐year‐old Romanian children: children abandoned to institutions then randomly assigned to remain in ‘care as usual’ (institutional care); children abandoned to institutions then randomly assigned to a foster care intervention; and community children who had never been institutionalized. Experiment 1 examined children's recognition of happy, sad, fearful, and angry facial expressions that varied in intensity. Children assigned to institutional care had higher thresholds for identifying happy expressions than foster care or community children, but did not differ in their thresholds for identifying the other facial expressions. Moreover, the error rates of the three groups of children were the same for all of the facial expressions. Experiment 2 examined children's ability to use facial expressions of emotion to guide social decisions about whom to befriend and whom to help. Children assigned to institutional care were less accurate than foster care or community children at deciding whom to befriend; however, the groups did not differ in their ability to decide whom to help. Overall, although there were group differences in some abilities, all three groups of children performed well across tasks. The results are discussed in the context of theoretical accounts of the development of emotion processing.  相似文献

Exposure to early psychosocial deprivation as a result of institutional care disrupts typical brain development. The Bucharest Early Intervention Project (BEIP) is the first longitudinal study to investigate the neurodevelopment of institutionalized infants randomized to a foster care (FCG) intervention versus care as usual (CAUG). Here, we present findings from a follow‐up assessment of brain electrical activity as indexed by resting EEG at age 16 years. In addition, we examined the effects of disruption of foster care placement (e.g. the number of moves among foster care placements) on brain electrical activity. Resting‐state EEG was collected from 48 CAUG, 46 FCG and 48 never institutionalized (NIG) control participants. Absolute (µV2) and relative (proportion) power were computed from eyes closed, resting EEG data for theta, alpha and beta frequency bands. The CAUG displayed higher relative theta and lower relative alpha power compared to the FCG at 16 years of age. The FCG showed brain activity comparable to the NIG. The results further showed that disruptions following the original foster care placement had an adverse effect on brain electrical activity. Within the foster care group, there were no effects of age of placement on EEG power. Placement of children who have experienced early institutional rearing into stable foster care settings ensure long‐term improvement in brain functioning.  相似文献

To test the hypothesis that age of first separation from a home environment is a factor in the emotional health of institutionalized boys, Rorschach protocols of 82 residents of Saint Francis Vocational School, a facility for deprived nondelinquent nonretarded youth aged 10 to 18, were examined. Seven Rorschach variables were used as dependent variables of emotional status. It was found that boys who had first been institutionalized before age 10 gave more color-dominant and pure color responses (p .005), and more responses with pathological overtones (p < .005), than did youth first placed at ages 10 to 13 or ages 14 to 17. Fixation was proposed as the basis for the group differences.  相似文献

Abstract

Neuropsychologists are often faced with the challenge of assessing older adults who exhibit both cognitive deficits and symptoms of depression. This study examined factors associated with diminished fluency in elderly adults. Three groups were tested: 54 community elderly, 35 institutionalized elderly, and 40 young adults using the Controlled Oral Word Association test. Significant incremental contributions to performance on verbal fluency included age, education, depression, and the interaction term for depression and functional impairment. Diminished verbal fluency was associated with depression among older adults who were not functionally impaired. the results suggest that variables other than cerebral integrity must be taken into consideration when interpreting older adults' performance on fluency tests.  相似文献

At 3 years of age the spontaneous language of 17 typically developing children was compared to two groups of toddlers who were at risk for language delay for very different reasons. One at-risk group, late talkers, appeared normal in all respects except for their delayed language. These 20 children scored at or below the fifteenth percentile for expressive vocabulary on the MacArthur Communicative Development Inventory (Fenson et al., 1993) when originally identified at 20-27 months of age and within the normal range on the Bayley Scales of Infant Development (Bayley, 1969). The other group, 21 children with unilateral focal brain injury, suffered localized damage to their brain prenatally, perinatally, or within the first 6 months of life. Results indicated that both of the at-risk groups were still significantly lower in vocabulary diversity and grammar at 3 years of age. There was also significantly greater variability in the at-risk groups than in the control groups, and in the children with focal brain injury than in the late talkers in both areas. The importance of language comprehension to development in this period was supported by two findings. First, children with focal brain injury had significantly lower scores than late talkers on the Index of Productive Syntax, a test of emerging grammar, and had been lower in comprehension on a standardized test of language comprehension a year earlier. Second, late talkers with delay in comprehension as well as production had significantly lower scores on IPSyn than those with normal comprehension, suggesting that they are at greater risk for continued delay. Qualitative analyses indicated that the at-risk groups produced the same kinds of errors, but that late talkers produced a substantially greater proportion of errors in obligatory contexts than did children with focal brain injury.  相似文献

The soaring cost of health care is a national problem that needs response at multiple levels, including that of the community. Reducing or limiting health care costs through interventions that emphasize the self-management of health may promote broader health care coverage, better quality of health care, and a sense of control over one's health. Therefore, it behooves community psychologists to perform cost analyses when testing interventions for people in a community. The present study investigated the effects of social support and education interventions on psychosocial variables, health status, and health care costs in older people with osteoarthritis. Participants were 363 members of a health maintenance organization (HMO), 60 years of age and older, with osteoarthritis. Participants were randomly assigned to one of three intervention groups (social support, education, or a combination of both) or to a control group. The results indicated that feelings of helplessness decreased in the intervention groups but not in the control group. All groups showed increases in self-efficacy and overall health status. In addition, health care costs increased less in the intervention groups than in the control group. Cost analysis was used to demonstrate that the monetary savings of the intervention greatly outweighed the cost of conducting the intervention. It appears that interventions can limit health care costs while improving health and increasing feelings of control for older people with osteoarthritis. Further, this paper demonstrates how a cost-benefit focus can benefit community studies.  相似文献

ABSTRACT

Two groups of Norwegian individuals 80 years of age and older, one living in nursing homes and one in the community, were compared with respect to loneliness, religiousness, purpose in life (PIL), and age group. There were no differences in loneliness identified between groups with regard to residence. Community residents between 80–89 years reported significantly higher loneliness scores than did the age group between 90–105 years. A majority of all subjects reported religion to be important, but age group comparisons yielded non-significant results. Residents living in the community reported significantly higher PIL scores than did residents in institutions. In addition, the community group 90–105 years old reported significantly higher PIL scores compared to the age group of 80–89 years. Analysis of variance showed significantly higher (negative) correlations between loneliness and purpose in life than between these phenomena and religiousness.  相似文献

Learning and memory impairment in rats fed a high saturated fat diet   总被引:4,自引:0,他引:4  
At the age of 1 month, three separate groups of Long-Evans rats were placed on 20% (w/w) fat (40% of calories) diets high in either saturated fatty acids (lard-based) or polyunsaturated fatty acids (soybean oil-based) or standard laboratory chow (Purina, 4.5% (w/w) fat). After 3 months, all rats were administered three tests of learning and memory--Olton's radial arm maze, a variable-interval delayed alternation task, and the Hebb-Williams maze series. The lard-fed group was impaired on all tests. The soybean oil-fed group was slightly impaired on some measures, relative to the chow-fed group, but consistently performed better than the lard-fed group. The results indicate that a diet high in saturated fatty acids can impair a wide range of learning and memory functions and are in line with biochemical and physiological evidence showing widespread effects of such diets on brain function.  相似文献

The Bene-Anthony Family Relations Test was administered to twenty normal, twenty-seven school disordered, and ten institutionalized emotionally disturbed preadolescent boys. Significant differences were obtained between and within groups. The more disturbed children tended to report more positive perceptions of family relationships, particularly their relationships with their oldest siblings. However, institutionalized children tended to perceive themselves more negatively than normal or school disordered children in the context of family relationships. Normal children, but not institutionalized children, tended to perceive their relationships with their oldest siblings as significantly more negative than their relationships to their parents. The data were interpreted as reflecting sibling rivalry and the operation of psychodynamic defenses.  相似文献

The current study examined processing speed in children two years post-treatment for brain tumors (BT) with radiation therapy (RT) compared to those treated with without RT. Participants included 59 children (4–17 years) with BT assessed as part of the Brain Radiation Investigative Study Consortium (BRISC). Processing speed was assessed at two time points: Time1 (3–9 months post-surgery) for 26 children who received whole brain or focal RT (RT group) and 33 treated without RT (no-RT group), and again two years later (Time2) for 42 participants (17 RT, 25 no-RT). Linear mixed effects (LME) regression analyses examined differences in cognitive and motor speed between groups and across visits, with age at Time1 (age1) treated as a moderating variable, and sex and primary tumor size as covariates. No effects for treatment group or visit were found for motor speed (Pegboard) or mean reaction time (Attention Network Task). On the Wechsler Processing Speed Index (PSI), the no-RT group performed better than the RT group, with a group-by-age interaction such that across visits, the difference between the no-RT and RT groups was larger among children who were older at initial treatment (≥10 years) than among those who were younger (<10 years). Cumulative brain injury earlier in life (tumor, surgery, plus RT) may result in greater impact on more complex tasks of cognitive efficiency. Children receiving RT showed reduced processing speed over time, with a larger group difference among those who were over 10 years at treatment.  相似文献

Collaboration is a ubiquitous approach to change, but is notoriously difficult and not definitively linked to desirable outcomes. Not surprisingly, the collaboration literature is replete with numerous facilitators and barriers to collaborative efforts. The current study aimed to develop a parsimonious model of factors influencing the success of collaborative efforts both internal and external to the council, including, (a) features of the council environment, (b) intermediate outcomes including the empowerment of members in the council context and the degree to which councils have generated social capital and (c) the extent to which collaborative efforts are occurring in a community context supportive of their aims. In particular, this study examines whether these factors affect the extent to which councils are positioned to achieve institutionalized change, or changes "in the text" that govern front line providers' (e.g., police, advocates) practices in the community response to intimate partner violence. Results suggest that perceived member empowerment, generation of social capital, and supportive community context are the most important predictors of the extent to which councils foster shifts in institutionalized change. Features of the council environment are only indirectly related to the degree to which institutionalized change is ultimately fostered as mediated by the generation of social capital. This suggests that the ability of members to act as change agents and the extent to which those in power support council efforts figure more prominently to facilitate or constrain council efforts than council functioning itself.  相似文献

Pedestrian-skills training procedures were compared using 30 mentally retarded institutionalized adults. Ten subjects were randomly assigned to a no-treatment control group and ten subjects were assigned to each of two modes of pedestrian-skills training. The training methods included a form of individualized classroom training consisting of the practice of correct behavior using movable figures on a scale model of an intersection, vs independence training which emphasized self-evaluation of performance, social reinforcement, sign recognition and the utilization of a mock-up of an intersection on the hospital grounds. Data were taken on sign recognition, verbal and performance based responses to classroom training of pedestrian skills, performance of skills at an intersection on the hospital grounds, and performance of pedestrian skills in the community. Independence training proved to be significantly more effective than no treatment or classroom training. In addition, classroom training proved to be significantly more effective than no treatment at all.  相似文献

A group of 16 children from a normal community population was compared with two groups of 16 children referred for clinical evaluation of hyperactivity. These three groups were matched on age, sex, and race. One of the clinic groups was matched with the community sample on IQ and social class as well, while the children in the other clinic group were mentally retarded and of somewhat lower social class. All children were observed in a standardized playroom for two 15-minute sessions, one under free play instructions and the other under instructions restricting activity and toy-changing behavior. The two groups of children referred for evaluation of hyperactivity had significantly higher playroom activity scores than controls under both instructional conditions and significantly higher toy-change scores under restrictive instructions. Parental ratings of activity were also significantly higher in both clinic groups than in the community group. The mentally retarded clinic sample did not differ from the other clinic sample on any of the measures of activity or toy switching.A preliminary version of this article was presented at the meeting of the American Psychological Association, Chicago, Illinois, August 30, 1975, as part of a Symposium on Hyperactive Children: Assessment, Treatment, and Outcome. This research was supported by U. S. Public Health Service, Maternal and Child Health Project No. 916 and by Grants HD-03110 and ES-01104.  相似文献

This article describes the perceptual motor, educational and social outcome of early motor delay in a group of 17-18 year old Finnish adolescents who were originally evaluated at age 5. The study group consisted of 65 adolescents: 22 with significant motor problems (or developmental coordination disorder, DCD), 23 with minor motor problems (intermediate group) and 20 controls. The goal of this study was to reassess the results obtained when they were age 15 and to determine whether the variables used earlier could still discriminate the adolescents at age 17. The results showed that at age 17 all perceptual motor tasks differentiated the three groups. The DCD group performed less well than the control group on all tasks, with the intermediate group situated between these two. Discriminant function analyses showed that more classification errors occurred between the control and intermediate groups at age 17 than at age 15, suggesting that the distinction between these groups becomes more difficult with age. In the educational domain, similar to the findings at age 15, the adolescents with DCD had the lowest WAIS scores and shortest school careers of the three groups. In the social domain, as found two years earlier, the DCD group had the lowest perceptions of athletic and scholastic competence while the intermediate and control groups did not differ. In addition, the interview results indicated that the three groups were in different stages of identity development. In sum, the outcome at age 17 was a replication of the results obtained at age 15 and suggests two developmental paths for those with early perceptual motor problems: 'persistence' and 'catching up'.  相似文献

Recent reports suggest that hormone therapy (HT) with estrogen may have a protective effect on the ageing brain and cognitive function. However, clinical evidence regarding the cognitive effects in menopausal women under HT has produced conflicting results. The purpose of the present study was to assess and compare the cognitive effects after 6 months of HT in 30 early postmenopausal women, who were divided into three groups as follows: group I, Therapy conjugated equine estrogen (ET) CEE 0.625 mg/day (n = 10); group II, Estrogen‐Progestin Therapy (EPT), CEE 0.625 mg/day plus, chlormadinone 1 mg/day (n = 10); and group III, the control group, who did not receive treatment (n = 10). The three groups were matched by age and years of education. Exclusion criteria were: central nervous system diseases, severe cardiac disease, and clinical history of cancer and depression. Subjects were tested using a comprehensive battery for the evaluation of attention, memory and executive functions, which was standardized and validated in Spanish‐speaking subjects. The rate of cognitive change was defined by the difference between the measurements at the sixth month minus the baseline score. Mean group differences were assessed with MANOVA, followed by one‐way ANOVA considering statistical significance when p < .05; the alpha significance level .05 was corrected using the Bonferroni procedure. The EPT group showed higher scores than the control group and ET group in the Total Attention Score and in the copy of the Rey‐Osterreith Complex Figure. The ET group showed significantly higher scores than the control group and the EPT group in the subtest of Spatial Backward Span and in the Immediate Face Codification. The short‐term positive effects observed with HT in this sample could be related to the stimulation of brain receptors and/or neurotrophic factors that are still present at this age.  相似文献

The present article reports a controlled intervention study concerning the effects of a nondirected use of pictures of works of art as a way of stimulating creativity in elderly institutionalized women. Participants were randomly allocated either to the intervention (n = 20) or to the control (n = 20) group. After the intervention significant improvement in ratings between the groups was measured, with the intervention group more open and flexible and with a stronger deposition to a creative behavior than subjects in the control group. They also showed greater freedom and variation than the control group in drawing circles and making pictures. In puzzle tests the intervention group constructed increasingly imaginative, irregular, and open alternatives with colored patterns. The control group constructed closed and black forms. Importantly, the status of increased creativity continued to exist four months after the intervention. No changes were seen in the control group. This group showed a rational and precautious personality.  相似文献

The community living preferences of 4 institutionalized adults with mild mental retardation were identified using photographs that depicted a variety of residential characteristics. Individuals then were taught to obtain information regarding their preferences during tours of community group homes, to report that information to their social worker, and to evaluate the homes based on the information obtained. A multiple baseline across participants design showed that all 4 participants substantially increased their skills at asking questions, reporting information, and evaluating homes. The results indicate that people with mental retardation can take an active role in major lifestyle decisions that others have typically made for them.  相似文献
