Māori adults recall earlier memories than New Zealand European or Chinese adults, highlighting the importance of memory in Māori culture. In this study, Māori preschool children and their mothers (N = 41) reminisced about a diverse range of past events, including everyday events, the child's birth, cultural rituals and the child's misbehaviour. Mothers also reported how frequently they discussed past events with their children, as well as their level of affiliation with Māori culture. Mothers who reported higher levels of cultural affiliation also reported reminiscing more frequently about a diverse range of past events. Mothers reminisced in more elaborative ways about everyday events with their children compared to birth stories, cultural rituals and misbehaviours. Maternal reminiscing about cultural rituals and misbehaviours, however, along with maternal reminiscing about everyday events and birth stories, were significantly correlated with children's memory across conversations. These results underscore the continued importance of reminiscing about culturally relevant events in Māori culture, and the newfound importance for Māori families of reminiscing about everyday events.  相似文献

Do adolescents remember imaginary companions (ICs) from early childhood? Researchers interviewed 46 adolescent participants in a prospective longitudinal study about their ICs from early childhood (age 5½). The existence of one or more ICs was documented in early childhood for 48% of children (G. Trionfi & E. Reese, 2009). At age 16, most adolescents had forgotten their early childhood ICs: Only 5 of the 23 participants who had early childhood ICs recalled those ICs later. Eight participants who had forgotten their early childhood ICs recalled a later IC, and four participants who did not have an IC at age 5 ½ reported one by age 16. Ten of the 23 participants who had early childhood ICs claimed never to have had an IC. Girls were more likely to recall their early childhood ICs. Retrospective reports of ICs in adolescence or later life may be unreliable for investigating differences between those with and without imaginary companions. Those with ICs may not be a homogenous group, with some creating ICs throughout childhood and some desisting from this behavior in early childhood. Findings indicate that both the remembering and forgetting of ICs has potential to illuminate cognitive and creative processes surrounding both memory and imagination.  相似文献

Recent mechanistic models of cognitive control define the normative level of control deployment as a function of the effort cost of exerting control balanced against the reward that can be attained by exerting control. Despite these models explaining empirical findings in adults, prior literature has suggested that adolescents may not adaptively integrate value into estimates of how much cognitive control they should deploy. Moreover, much work in adolescent neurodevelopment casts social valuation processes as competing with, and in many cases overwhelming, cognitive control in adolescence. Here, we test whether social incentives can adaptively increase cognitive control. Adolescents (Mage = 14.64, 44 male, N = 87) completed an incentivized cognitive control task in which they could exert cognitive control to receive rewards on behalf of real peers who were rated by all peers in their school grade as being of either high- or low-status. Using Bayesian modeling, we find robust evidence that adolescents exert more cognitive control for high- relative to low-status peers. Moreover, we demonstrate that social incentives, irrespective of their high- or low-status, boost adolescent cognitive control above baseline control where no incentives are offered. Findings support the hypothesis that the cognitive control system in early adolescence is flexibly modulated by social value.  相似文献

Given the increasing complexity of the tasks and skills needed in modern society, developing effective training strategies is of tremendous practical importance. Furthermore, training that improves performance of both trained and untrained tasks would be highly efficient. In the present study, we examined how directed training contributes to skill acquisition, and more importantly, to engendering transfer of training to untrained tasks. Participants learned a complex video game for 30 h (Space Fortress, Donchin, Fabiani, & Sanders, 1989) using one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET) in which participants simply practiced the game to obtain the highest overall score. We compared game performance, retention of training gains, and transfer of training to untrained tasks as a function of the training regimen. Compared to FET, HVT learners reached higher levels of mastery on the game and HVT was particularly beneficial for initially poor performing participants. This benefit persisted seven months after training. However, contrary to expectation, both HVT and FET were unsuccessful in producing transfer to untrained tasks compared to a group that received limited game experience, suggesting that directed training and practice can produce task-specific improvements, but improvements do not necessarily transfer from trained to untrained tasks.  相似文献

A signal detection analysis assessed the extent to which forced confabulation results from a change in memory sensitivity (d a ), as well as response criterion (β). After viewing a crime video, participants answered 14 answerable and 6 unanswerable questions. Those in the voluntary guess condition had a “don’t know” response option; those in the forced guess condition did not. One week later, the same questions were answered using a recognition memory test that included each participant’s initial responses. As was predicted, on both answerable and unanswerable questions, participants in the forced guess condition had significantly lower response criteria than did those who voluntarily guessed. Furthermore, on both answerable and unanswerable questions, d a scores were also significantly lower in the forced than in the voluntary guess condition. Thus, the forced confabulation effect is a real memory effect above and beyond the effects of response bias; forcing eyewitnesses to guess or speculate can actually change their memory.  相似文献

We present baseline data and describe the utility of a community engaged, culturally relevant approach to recruiting African American youth and families for phase I of The AAKOMA Project. The AAKOMA Project is a two phase treatment development study to improve mental health service use among depressed African American youth. We completed capacity building activities using a community engaged framework and Community Based Participatory Research (CBPR) methods. Replicating the (Alvarez et al. in West J Nurs Res 28:541–560, 2006) model of systematic community outreach enhanced our ability to effectively recruit partners and evaluate outreach efforts as demonstrated by our Recruitment Success Factor (RSF—i.e. ‘an adjusted ratio of eligible participant yield to contacts made’). Using the chi-square goodness-of-fit statistic; we compared the RSFs of the various modes of participant study entry to determine which was most effective. Our target enrollment was 56 persons. We recruited 130 and enrolled 57. Our baseline data is drawn from a gender balanced and socioeconomically diverse sample who participated in youth focus groups and individual interviews and adult focus groups. We identified 3 study participant referral modes (self-referral, provider referral and participant-to-participant referral) with multiple sources per mode and an overall RSF of 0.41. Study findings support the effectiveness of assiduous and systematic community interaction, reflective review of recruitment efforts and the importance of disseminating information on strategic recruitment processes for engaging diverse populations in clinical research.  相似文献

This paper presents an empirical examination of the Situational Leadership® Model (SLM), which is used extensively in management training programs by major corporations and government agencies. Data from 675 salespersons and 41 branch managers in the insurance industry did not support the hypothesis that leadership styles prescribed by the SLM were associated with superior sales performance. The four styles described by the SLM were also tested, with an exploratory regression, in terms of their relative effects on sales performance. Agents working for managers who preferred the high-task, low-relationship style performed better than did agents working for managers who preferred other styles. Some implications for future research and practice are discussed.  相似文献

Abstract

Many HIV-positive individuals dissatisfied with allopathic approaches to disease management have turned to complementary and alternative medicines (CAM). Although people use CAM for a variety of reasons (e.g., symptom management, holistic approach towards healthcare, improved immunity), the psychological benefits that these treatments may have are still not fully understood. The present study was designed to further previous research that demonstrated relationships between CAM use, stress appraisals, and coping behaviors. HIV-positive individuals (N= 127) completed measures assessing stress appraisals, coping, psychological adjustment, satisfaction with life, and immune functioning. After controlling for ethnicity and sexual orientation, stress appraisals and coping behaviors were found to be related to CAM use. Further, curvilinear relationships between CAM use and adjustment emerged, suggesting that some CAM use may be adaptive. Self-reported immune measures were unrelated to CAM use. In all, it appears that CAM use may be a complex form of coping that assists individuals in adjusting to a life-threatening illness. The implications of these findings with respect to adherence to highly active antiretroviral therapies (HAART) are also discussed.  相似文献

Hippocampal damage and amnesia following hypoxia and ischemia are described in the few published adult cases of suicide attempt by hanging. However, a recent review (Caine &; Watson, 2000 Caine, D. and Watson, J. D. 2000. Neuropsychological and neuropathological sequelae of cerebral anoxia: A critical review. Journal of the International Neuropsychology Society, 6: 8699. [CROSSREF][Crossref], [PubMed], [Web of Science ®] [Google Scholar]) suggests a variable pattern of brain involvement and neuropsychological impairments following hypoxic-ischemic injury that may or may not involve amnesia. To help clarify the impact of hanging on the developing brain, we examined neuropsychological functioning in two adolescents who survived suicide attempt by hanging. Despite differences in Glasgow Coma Scale (GCS), coma duration, and structural imaging findings, both patients had similar IQ (VIQ > PIQ) and presented with various combinations of deficits in expressive/receptive language, visual-constructional and perceptual ability, processing speed, attention, working memory, and/or executive functioning shortly after injury. In spite of their similarities, only one of the patients presented with classic amnesia symptoms in his early recovery. This patient was evaluated 1 year postinjury, and persistent deficits in processing speed and memory encoding were noted. Several hanging-related variables, including longer estimated hanging duration, greater weight, and severe airway edema, were thought to place this patient at increased risk for cognitive deficits. Clinical MRI scans of this patient obtained 6 weeks postinjury revealed mild volume loss as well as abnormalities in bilateral superior cortex. However, CT and MRI scans obtained throughout early recovery did not reveal overt evidence of injury to specific memory-related structures. Comprehensive neuropsychological evaluation of all adolescent survivors of suicide attempt by hanging is recommended, as a variety of postacute cognitive deficits were observed in these patients despite relatively short (≤ 15 minutes) estimated hanging durations.  相似文献

The present study examined messages about mental illness in 14 contemporary Christian self-help bestsellers. Content analysis revealed that most texts focused upon depression. Categories of textual units included Underlying Assumptions Regarding Depression, Representations of Depression, Roots/Causes/Reasons for Depression, and Christian Responses to Depression. Demonic influence was the most frequently cited reason for depression. Other reasons included negative cognitions, failure as a Christian, and negative emotions. Christian responses to depression included trusting God, religious activity, and individual willpower. Discussion of these results focused upon the problematic impact of these messages upon individuals with depression, and upon suggestions for reducing mental illness stigma in religious communities.  相似文献
