In two experiments testing age differences in the subjective experience of listening, which we call meta-audition, young and older adults were first trained to learn pairs of semantic associates. Following training, both groups were tested on identification of words presented in noise, with the critical manipulation being whether the target item was congruent, incongruent, or neutral with respect to prior training. Results of both experiments revealed that older adults compared to young adults were more prone to "false hearing," defined as mistaken high confidence in the accuracy of perception when a spoken word had been misperceived. These results were obtained even when performance was equated across age groups on control items by reducing the noise level for older adults. Such false hearing is shown to reflect older adults' heavier reliance on context. Findings suggest that older adults' greater ability to benefit from semantic context reflects their bias to respond consistently with the context, rather than their greater skill in using context. Procedures employed are unique in measuring the subjective experience of hearing as well as its accuracy. Both theoretical and applied implications of the findings are discussed. Convergence of results with those showing higher false memory, and false seeing are interpreted as showing that older adults are less able to constrain their processing in ways that are optimal for performance of a current task. That lessened constraint may be associated with decline in frontal-lobe functioning. 相似文献

Affording Emerging Adulthood: Parental Financial Assistance of their College-Aged Children 总被引:1,自引:0,他引:1
Laura M. Padilla-Walker Larry J. Nelson Jason S. Carroll 《Journal of Adult Development》2012,19(1):50-58
The purpose of this study was to examine parents’ attitudes about and patterns of providing financial assistance to their
children during college, and how varying levels of parental financial support were related to children’s beliefs (e.g., perceptions
of adulthood), behaviors (e.g., work hours, drinking, and drug use), and identity development. The sample consisted of 402
undergraduate students (62% women) recruited from four college sites across the United States (M age = 19.89), and one of their parents (310 mothers and 92 fathers). Using cluster analysis, results suggested four distinct
approaches to parental financial involvement and found that emerging adults’ beliefs, behaviors, and identity development
differed as a function of parents’ cluster membership. Discussion focuses on implications for emerging adult children whose
parents endorse varying levels of financial involvement. 相似文献

Working memory (WM) is considered a core deficit in Attention-Deficit/ Hyperactivity Disorder (ADHD), with numerous studies demonstrating impaired WM among children with ADHD. We tested the degree to which WM in children with ADHD was improved by performance-based incentives, an analog of behavioral intervention. In two studies, WM performance was assessed using a visuo-spatial n-back task. Study 1 compared children (ages 9-12?years) with ADHD-Combined type (n?=?24) to a group of typically developing (TD) children (n?=?32). Study 1 replicated WM deficits among children with ADHD. Incentives improved WM, particularly among children with ADHD. The provision of incentives reduced the ADHD-control group difference by approximately half but did not normalize WM. Study 2 examined the separate and combined effects of incentives and stimulant medication among 17 children with ADHD-Combined type. Both incentives and a moderate dose of long-acting methylphenidate (MPH; ~0.3?mg/kg t.i.d. equivalent) robustly improved WM relative to the no-incentive, placebo condition. The combination of incentives and medication improved WM significantly more than either incentives or MPH alone. These studies indicate that contingencies markedly improve WM among children with ADHD-Combined type, with effect sizes comparable to a moderate dose of stimulant medication. More broadly, this work calls attention to the role of motivation in studying cognitive deficits in ADHD and in testing multifactorial models of ADHD. 相似文献

Studies of recognition typically involve tests in which the participant’s memory for a stimulus is directly questioned. There
are occasions however, in which memory occurs more spontaneously (e.g., an acquaintance seeming familiar out of context).
Spontaneous recognition was investigated in a novel paradigm involving study of pictures and words followed by recognition
judgments on stimuli with an old or new word superimposed over an old or new picture. Participants were instructed to make
their recognition decision on either the picture or word and to ignore the distracting stimulus. Spontaneous recognition was
measured as the influence of old vs. new distracters on target recognition. Across two experiments, older adults and younger
adults placed under divided-attention showed a greater tendency to spontaneously recognize old distracters as compared to
full-attention younger adults. The occurrence of spontaneous recognition is discussed in relation to ability to constrain
retrieval to goal-relevant information. 相似文献

In three experiments, we examined the mechanisms by which prior experience with proactive interference (PI) diminished its
effects. Cued recall tasks conforming to an A–B, A–D paradigm were used to induce PI effects. Experiment 1 showed that reduced
PI was not due to a reduction in attention to the source of PI. Experiment 2 revealed that participants’ awareness of PI effects
on memory performance increased with experience, resulting in a shift in encoding processes. Experiment 3 demonstrated that
changes in encoding provided additional support for recollection that further enhanced participants’ ability to constrain
their retrieval processing to the appropriate source of information at the time of test. These results can be interpreted
as showing that experience with PI enhances awareness of its effects and allows individuals to adjust their learning and retrieval
strategies to compensate for such effects. 相似文献

All caregiving takes place in multiple political contexts and assumes or actually furthers various political agendas, whether acknowledged or not. When strategically incorporated into pastoral and spiritual care, politically responsive actions may enhance the practice of care. When disaster strikes a community, ritual engagement of the larger public context provides a significant opportunity for pastoral caregivers to function as public pastoral theologians and to influence the corporate response to communal challenges. In these circumstances of community vulnerability, pastoral caregivers and communities of faith are positioned to provide spiritual care that combines solace and safety for the victims with guidance and shaping influence on the ritual practices and rhetorical interpretations called upon to assist the community to endure, respond, and heal. This article examines some central political aspects of the pastoral caregiver’s repertoire that might further a stricken community’s ritual and rhetorical resources necessary to sustain life, share loss, reclaim goodness, and rebuild for a strong future. Drawing upon a view of lamentation as a tri-partite process of sharing anguish, interrogating causes, and reinvesting in hope, I suggest how the spiritual and pastoral caregiver may collaboratively participate in a “disaster-response matrix” that organizes corporate responses to catastrophic disaster. This article pays particular attention to macro-, meso-, and micro-level political negotiations necessary to ensure respect for diversity and shared responsibility in creating rituals, memorials, and public narratives at the onset of disaster and in its aftermath over the generations. Illustrations from the experience of religious caregivers at Columbine, Hurricane Katrina, 9/11, Aurora, Newtown, and Boston are presented to guide pastoral engagement of civil society in disruptive times. 相似文献

Abstract: The common practice of giving (comparing, rejecting and inferring) explanations of phenomena is at the root of articulate learning, including the enterprises we collect under the noun ‘science’. The way that practice privileges a single item from the myriad relevant to any phenomenon tells us something about articulateness itself. 相似文献
