Autobiographical memory research documents increased access in the number of memories recalled by emerging adults (ages 18–25)
with stable, clearly defined self-concepts. Very little research has examined the relationship between self-concept clarity
and the episodic and semantic components of emerging adults’ autobiographical recollections. This study examined the relationship
between episodic and semantic autobiographical memory and self-concept clarity in 100 undergraduate students. Contrary to
previous findings, which indicated that stable self-beliefs may be used to facilitate access to episodic memories, the results
suggested that self-concept clarity may not be associated with memory specificity. Instead, self-concept clarity was associated
with recall of events involving cooperative social interactions. Results further showed that older age was associated with
higher SCC. The implications of these results are discussed within the context of the theoretical literature concerning the
relation between autobiographical memory and the development of the self-concept during emerging adulthood. 相似文献

Choosing and using geospatial displays: effects of design on performance and metacognition 总被引:1,自引:0,他引:1
Interactive display systems give users flexibility to tailor their visual displays to different tasks and situations. However, in order for such flexibility to be beneficial, users need to understand how to tailor displays to different tasks (to possess "metarepresentational competence"). Recent research suggests that people may desire more complex and realistic displays than are most effective (Smallman & St. John, 2005). In Experiment 1, undergraduate students were tested on a comprehension task with geospatial displays (weather maps) that varied in the number of extraneous variables displayed. Their metacognitive judgments about the relative effectiveness of the displays were also solicited. Extraneous variables slowed response time and increased errors, but participants favored complex maps that looked more realistic about one third of the time. In Experiment 2, the eye fixations of undergraduate students were monitored as they performed the comprehension task. Complex maps that looked more realistic led to more eye fixations on both task-relevant and task-irrelevant regions of the displays. Experiment 3 compared performance of experienced meteorologists and undergraduate students on the comprehension and metacognitive tasks. Meteorologists were as likely as undergraduate students to prefer geographically complex (realistic) displays and more likely than undergraduates to opt for displays that added extraneous weather variables. However, meteorologists were also slower and less accurate with complex than with simple displays. This work highlights the importance of empirically testing principles of visual display design and suggests some limits to metarepresentational competence. 相似文献

Objective: To empirically identify the appropriate symptom threshold for hyperactivity-impulsivity for diagnosis of ADHD in adults. Method: Participants were 88 adults (M [SD] age = 41.69 [11.78] years, 66% female, 16% minority) meeting formal DSM-IV criteria for ADHD combined or predominantly inattentive subtypes based on a structured diagnostic interview keyed to DSM-IV (Conners' Adult ADHD Diagnostic Interview for DSM-IV [CAADID]). All participants also completed the Conners' Adult ADHD Rating Scale (CAARS), which was normed on the general adult population and includes subscales for DSM-IV inattentive and DSM-IV hyperactive-impulsive symptoms. A T-score threshold of 65 (at least 1.5 SD above population mean) on the CAARS DSM-IV hyperactive-impulsive dimension was used to identify participants with empirically elevated symptom severity. Results: Of 88 participating adults, 48 (55%) had a T-score of at least 65 (1.5 SD) on the CAARS DSM-IV Hyperactive-Impulsive scale. Of these, only 25 (52%) met the DSM-IV cutoff of six hyperactive-impulsive symptoms on the CAADID. Thus, approximately half of those who reported empirically elevated hyperactive-impulsive complaints on the CAARS did not concurrently meet the six-symptom DSM-IV cutoff on the CAADID. An alternative cutoff of four hyperactive-impulsive symptoms on the CAADID captured 39 (81%) cases identified by the CAARS. Conclusion: In adults, mandating at least six hyperactive-impulsive symptoms excludes a significant percentage (almost half) of adults who are at least 1.5 SD above the population mean on a dimensional measure of hyperactivity-impulsivity. These data provide a compelling basis for lowering the symptom threshold of hyperactivity-impulsivity for adults in the DSM-5. 相似文献

Bilingualism: consequences for mind and brain 总被引:1,自引:0,他引:1
Building on earlier evidence showing a beneficial effect of bilingualism on children's cognitive development, we review recent studies using both behavioral and neuroimaging methods to examine the effects of bilingualism on cognition in adulthood and explore possible mechanisms for these effects. This research shows that bilingualism has a somewhat muted effect in adulthood but a larger role in older age, protecting against cognitive decline, a concept known as 'cognitive reserve'. We discuss recent evidence that bilingualism is associated with a delay in the onset of symptoms of dementia. Cognitive reserve is a crucial research area in the context of an aging population; the possibility that bilingualism contributes to cognitive reserve is therefore of growing importance as populations become increasingly diverse. 相似文献

Although the study of brain states is an old one in neuroscience, there has been growing interest in brain state specification owing to MRI studies tracing brain connectivity at rest. In this review, we summarize recent research on three relatively well-described brain states: the resting, alert, and meditation states. We explore the neural correlates of maintaining a state or switching between states, and argue that the anterior cingulate cortex and striatum play a critical role in state maintenance, whereas the insula has a major role in switching between states. Brain state may serve as a predictor of performance in a variety of perceptual, memory, and problem solving tasks. Thus, understanding brain states is critical for understanding human performance. 相似文献

This paper examines the effects of group performance anxiety on the attrition of women and minorities from science, math, and engineering majors. While past research has relied primarily on the academic deficits and lower socioeconomic status of women and minorities to explain their absence from these fields, we focus on the impact of stereotype threat—the anxiety caused by the expectation of being judged based on a negative group stereotype. Using data from the National Longitudinal Survey of Freshmen, our findings indicate that minorities experience stereotype threat more strongly than whites, although women do not suffer from stereotype threat more than men. Our findings also reveal that stereotype threat has a significant positive effect on the likelihood of women, minorities, and surprisingly, white men leaving science, technology, engineering and math majors. 相似文献

This study aims at illustrating the interest of a methodology of exploration of identity dynamics, the IMIS(Zavalloni & Louis-Guerin, 1984), for the elaboration of the professional project. Psychosocial identity is a system of representations of oneself and the world animated by the paradox of being identical and distinct at the same time. This system justifies ways of thought and action, that are retrieved in identity strategies. Action is presented as a medium-term project, endowed with a function of regulation of identity and capability representations that it conveys and validates(Costalat-Founeau, 2008). The project therefore leans upon the cognitive substrate of experience. Action doesn’t follow the project, both are interwoven in a common perspective defined by intentional objectives(Young & Valach, 2006). 相似文献

Sustained treatment attendance has been reported to be poor in publicly funded community-based clinic settings serving children and families. Several child and family characteristics have been shown to predict attendance in community-based care, but virtually no research has been conducted to examine how experiences in care, including psychotherapists' within-session practices, influence client attendance. The goal of this exploratory study was to examine how observed practice within sessions, in particular the extent to which therapists delivered elements consistent with evidence-based practices, impacts total number of sessions attended, while accounting for an array of other potential predictors. Participants include 181 children ages 4-13 and their parents entering a new episode of care for disruptive behavior problems in publicly funded clinics. Data sources include administrative billing records on treatment attendance; coded videotaped treatment sessions; and self-reports from children, parents, and therapists. Results indicate that parent education, service funding source, parent alliance with therapist, and therapist experience predicted number of sessions attended; intensity of evidence-based treatment techniques delivered to children was marginally associated with attendance (p = .059). Implications for improving engagement in community-based care are discussed. 相似文献

‘Contract cheating’ has recently emerged as a form of academic dishonesty. It involves students contracting out their coursework
to writers in order to submit the purchased assignments as their own work, usually via the internet. This form of cheating
involves epistemic and ethical problems that are continuous with older forms of cheating, but which it also casts in a new
form. It is a concern to educators because it is very difficult to detect, because it is arguably more fraudulent than some
other forms of plagiarism, and because it appears to be connected to a range of systemic problems within modern higher education.
This paper provides an overview of the information and literature thus far available on the topic, including its definition,
the problems it involves, its causal factors, and the ways in which educators might respond. We argue that while contract
cheating is a concern, some of the suggested responses are themselves problematic, and that best practice responses to the
issue should avoid moral panic and remain focussed on supporting honest students and good academic practice. 相似文献

As part of a larger research project on couple therapy for depression, this qualitative case study examines the nature of dialogue. Drawing on Bakhtinian concepts, the investigation shows how the conversation shifts from a monologue to dialogue. Among the findings are: first, the process of listening is integral to the transforming experience. That is, the careful listening of the therapist can evoke new voices, just as the experience of one of the partners’ “listening in” to the conversation between the other partner and the therapist can create movement and new trajectories. The latter is a qualitative difference between dialogic therapy with a couple and that with an individual. Second, the therapist not only acts as creative listener, but as the dialogue unfolds, actively contributes to meaning‐making. Third, the study upholds having a team of researchers as a polyphonic forum and the usefulness of Bakhtinian concepts in clinical research on dialogue in multi‐actor sessions. 相似文献
