The goal of this study was to examine how individual variation in readers’ skills and, in particular, their background knowledge
about a text are related to text memory. Recollection and familiarity estimates were obtained from remember and know judgments
to text ideas. Recollection estimates to old items were predicted by readers’ background knowledge, but not by other comprehension-related
factors, such as word-decoding skill and working memory capacity. False alarms involving recollection of new items (inferences)
were diminished as a function of verbal ability, working memory capacity, and reasoning but increased as a function of background
knowledge. The results suggest that recollection indexes the reader’s ability to construct a text representation in which
text ideas are integrated with relevant domain knowledge. Moreover, these results highlight the importance of background knowledge
in explaining individual variation in comprehension and memory for text. 相似文献

The present study dissociated the immediate neural costs from the subsequent neural consequences of integrating time shifts into our mental representations of events. Event-related potentials were recorded as participants read scenarios that included words referring to short temporal shifts (e.g., after one second), moderate temporal shifts (e.g., after one hour), or long temporal shifts (e.g., after one year). These words were followed by repeated noun-phrase anaphors, which are preferred as referents for information no longer in attentional focus. The N400 was measured as an index of online conceptual integration. As the discourse unfolded, the N400 was larger for long- (e.g.,year) than for short- (e.g., second) shift words. For the anaphor, the N400 was modulated in the opposite direction. Thus, the introduction of a temporal discontinuity leads to immediate neural integration costs, as well as to decreased accessibility of earlier information. 相似文献

This study investigated the effects of a dependent group-oriented contingency on the supportive and non-supportive fair play behaviors of 6th grade students engaged in volleyball games as part of their physical education instruction. Six students, one male and one female per class, from three classes, identified as demonstrating low incidences of supportive behaviors during volleyball games, were participants in this study. A multiple baseline across classes design was used to examine the data. During baseline few incidences of non-supportive behaviors occurred among all six students. However, the participants seldom displayed supportive behaviors during games (i.e., encouraged each other). Following the introduction of the dependent group contingency, supportive behaviors for all participants increased. Follow-up data, collected in an alternative setting, indicated variable maintenance. The results are discussed in the context of group contingencies and social behaviors in sports. 相似文献

We conducted a scoping review to characterize the role of caregiver involvement in behavior-analytic research. We reviewed eight behavioral-learning journals from 2011–2022 for works that included children or caregivers as participants and characterized caregiver involvement as passive (implications for caregivers, input, social validity) and active (implementation, caregiver behavior, training, caregiver-collected data). The review identified 228 studies, and almost all (96.1%; n = 219) involved caregivers in some capacity; 94.3% (n = 215) had passive involvement (26.8% had only passive involvement; n = 61), 69.3% (n = 158) had active involvement (1.8% had only active involvement; n = 4), and 3.9% (n = 9) had neither passive nor active involvement. Involvement generally increased over publication years. The most common types of involvement were implications for caregivers, implementation, and input; caregiver-collected data were rare. We propose considerations when engaging caregivers in research and suggest new avenues of inquiry related to caregivers' treatment objectives and social validity, treatment implementers, and caregiver-collected data. 相似文献

ABSTRACT— Skilled performance, whether it involves rapid and accurate motor movements (such as playing a video game or using a scalpel in the operating room) or a high degree of domain knowledge (such as finding a small tumor in an X-ray or writing a journal article) typically involves learning and practice over an extended period of time. In light of recent theory and empirical research, I consider two enduring issues associated with skill acquisition: whether individuals become more alike in performance or more different over the course of skill acquisition, and what the determinants of individual differences in skilled performance are. Two broad classes of tasks are considered: tasks that involve speed and accuracy of motor movements and tasks that primarily involve domain knowledge. Issues of practice, ability, and other determinants of skilled performance such as gender and aging are discussed. 相似文献

Up until recently, it had been assumed that attentional biases for negative information do not exist in depression. However studies using post-conscious exposure durations have produced contradictory results. The limitations of common attentional tasks, suitability of stimulus materials and differences in stimulus duration times may have contributed to these inconsistencies. We aimed to address many of these issues and examine attentional responses in major depression at two post-conscious exposure times. We also investigated possible roles for rumination and distraction in increasing and lessening attentional biases for negative information. We used a fully controlled experimental design to test the effects of both induced and trait rumination and distraction on attention in patients with major depression and healthy controls. Attention was assessed using the dot-probe task. The findings revealed an attentional bias for negative information in depressed patients only at the longer post-conscious exposure duration. Furthermore although this bias was not influenced by either induced or trait distraction, it was related to trait rumination. Overall, the results showed that depression is associated with a strategic attentional bias towards negative information and that this bias is stronger in individuals who habitually ruminate. 相似文献

Everyday speech is littered with disfluency, often correlated with the production of less predictable words (e.g., Beattie & Butterworth [Beattie, G., & Butterworth, B. (1979). Contextual probability and word frequency as determinants of pauses in spontaneous speech. Language and Speech, 22, 201-211.]). But what are the effects of disfluency on listeners? In an ERP experiment which compared fluent to disfluent utterances, we established an N400 effect for unpredictable compared to predictable words. This effect, reflecting the difference in ease of integrating words into their contexts, was reduced in cases where the target words were preceded by a hesitation marked by the word er. Moreover, a subsequent recognition memory test showed that words preceded by disfluency were more likely to be remembered. The study demonstrates that hesitation affects the way in which listeners process spoken language, and that these changes are associated with longer-term consequences for the representation of the message. 相似文献

The forces of attraction–selection–attrition have been hypothesized to create homogeneity of personality within organizations, and vocational choice theory predicts that these forces lead to a ‘modal personality’ within given occupations. This study compared the homogeneity of a set of personality characteristics for 6582 incumbents from eight organizations in eight occupations. The results indicated that (1) the homogeneity hypothesis was supported both within organizations as well as within occupations; and (2) the homogeneity within occupations was higher than that found in organizations. 相似文献
