Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success in word recognition varied with age and level of vocabulary development, and with the perceptual integrity of the word. Recognition was best overall for unaltered words, lower for time-compressed words, and significantly lower in low-pass-filtered words. Reaction times were fastest in compressed, followed by unaltered and filtered words. Results showed that children were able to recognize familiar words in challenging conditions and that productive vocabulary size was more sensitive than chronological age as a predictor of children's accuracy and speed in word recognition. 相似文献

A relationship between perfectionism and religiosity has been suggested in the literature, and this relationship is clarified
further when the adaptive and maladaptive dimensions of both constructs are compared. Literature in both areas implicates
the idea of a rigid and inflexible personality style that may explain why well meaning high standards can be associated with
negative outcomes such as perfectionism. This investigation examined the relationship of perfectionism and religiosity, using
adaptive and maladaptive dimensions, as mediated by psychological inflexibility. Validated measures of perfectionism, religiosity,
and psychological inflexibility were given to 376 undergraduate college students in an anonymous online survey. Adaptive perfectionism
(high standards) was found to be significantly correlated (r = .26, p < .01, two-tailed) with adaptive religiosity (intrinsic orientation). Maladaptive perfectionism (discrepancy) was found to
be significantly correlated (r = .13, p < .05, two-tailed) with maladaptive religiosity (extrinsic orientation). Psychological inflexibility was found to be significantly
correlated with the maladaptive dimensions of both perfectionism and religiosity. It was also shown to mediate the relationship
between maladaptive (extrinsic) religiosity and maladaptive (discrepancy) perfectionism. Implications and future directions
are discussed. 相似文献

Analysis of acoustic interactions between animals in active choruses is complex because of the large numbers of individuals present, their high calling rates, and the considerable numbers of vocalizations that either overlap or show close temporal alternation. The authors describe a methodology for recording chorus activity in bullfrogs (Rana catesbeiana) using multiple, closely spaced acoustic sensors that provide simultaneous estimates of sound direction and sound characteristics. This method provides estimates of location of individual callers, even under conditions of call overlap. This is a useful technique for understanding the complexity of the acoustic scene faced by animals vocalizing in groups. 相似文献

The present study investigated dysphoric individuals' self‐referential processing of autobiographical memories and future personal events, in relation to specificity and response latency. Dysphoric individuals (n = 17) and nondysphoric controls (n = 17) were selected from a larger sample based on self‐reported depression. Participants completed an autobiographical memory task (AMT) and a future event task (FET), using pleasant and unpleasant (anxiety‐relevant, depression‐relevant) emotional word cues. In response to each emotional cue, participants were required to access and write down a specific personal memory and future event, respectively. Consistent with the hypotheses, dysphoric individuals were less specific in describing pleasant and unpleasant experiences (particularly pleasant), irrespective of time condition. As expected, dysphoric individuals' specificity for distinct depression‐relevant and anxiety‐relevant experiences did not differ significantly. As predicted, all participants were less specific in describing future personal events than in recalling personal memories. As predicted, dysphoric individuals took longer to think of pleasant memories and pleasant future experiences than controls but, as expected, groups did not differ significantly on mean reaction times for past and future unpleasant experiences. Overall, the data showed a degree of consistency in participants' past and future‐oriented processing of self‐referential material. Although considerable research has investigated autobiographical memories in relation to emotional disturbance, the present findings suggest that constructing future emotional experiences is also an important aspect of mental health. 相似文献

Psychosocial treatments for chronic pain are effective. There is a need, however, to understand the processes involved in determining how these treatments contribute to behavior change. Control and acceptance strategies represent two potentially important processes involved in treatment, although they differ significantly in approach. Results from laboratory-based studies suggest that acceptance-oriented strategies significantly enhance pain tolerance and behavioral persistence, compared with control-oriented strategies. There is a need, however, to investigate processes of acceptance and control directly in clinical settings. The present study investigated the effects of three brief instructional sets (pain control, pain acceptance, continued practice) on demonstrated physical impairment in 74 individuals with chronic low back pain using an analogue experimental design. After controlling for baseline performance, the pain acceptance group demonstrated greater overall functioning on a set of 7 standardized physical tasks relative to the other two groups, which did not differ from one another. Further, the acceptance group exhibited a 16.3% improvement in impairment, whereas the pain control group worsened by 8.3% and the continued practice group improved by 2.5%. These results suggest that acceptance may be a key process involved in behavior change in individuals with chronic pain. 相似文献

The processing of words and pictures representing actions and objects was tested in 21 aphasic patients and 20 healthy controls across three word production tasks: picture-naming (PN), single word reading (WR) and word repetition (WRP). Analysis 1 targeted task and lexical category (noun-verb), revealing worse performance on PN and verb items for both patients and control participants. For Analysis 2 we used data collected in a concurrent gesture norming study to re-categorize the noun-verb items along hand imagery parameters (i.e., objects that can/cannot be manipulated and actions which do/do not involve fine hand movements). Here, patients displayed relative difficulty with the 'manipulable' items, while controls displayed the opposite pattern. Therefore, whereas the noun-verb distinction resulted simply in lower verb accuracy across groups, the 'manipulability' distinction revealed a 'double-dissociation' between patients and control participants. These results carry implications for theories of embodiment, lexico-semantic dissociations, and the organization of meaning in the brain. 相似文献

We present the first direct comparison of language production in brain-injured children and adults, using age-corrected z scores for multiple lexical and grammatical measures. Spontaneous speech samples were elicited in a structured biographical interview from 38 children (5-8 years of age), 24 with congenital left-hemisphere damage (LHD) and 14 with congenital right-hemisphere damage (RHD), compared with 38 age- and gender-matched controls, 21 adults with unilateral injuries (14 LHD and 7 RHD), and 12 adult controls. Adults with LHD showed severe and contrasting profiles of impairment across all measures (including classic differences between fluent and nonfluent aphasia). Adults with RHD (and three nonaphasic adults with LHD) showed fluent but disinhibited and sometimes empty speech. None of these qualitative or quantitative deviations were observed in children with unilateral brain injury, who were in the normal range for their age on all measures. There were no significant differences between children with LHD and RHD on any measure. When LHD children were compared directly with LHD adults using age-corrected z scores, the children scored far better than their adult counterparts on structural measures. These results provide the first systematic confirmation of differential free-speech outcomes in children and adults and offer strong evidence for neural and behavioral plasticity following early brain damage. 相似文献
