The cohesive use of referential language in narrative production reveals communicative goals as well as specific aspects of language use. A formalism for analyzing pronominal cohesion was developed and applied to the narrative discourse of three hemidecorticate adolescents. The results revealed hemisphere-dependent differences in overall narrative skill as well as distinct individual discourse strategies. Neither left hemidecorticate planned narration in extended discourse units: One demonstrated a linear and highly explicit discourse style with redundant over-statement of referent nouns and the other produced narratives cluttered with pronouns of both correct and ambiguous reference, relying on nonpersonal pronouns at considerable cost to narrative specificity. The right hemidecorticate produced narratives that were more economical in form and richer in content: He was the only subject able to maintain simultaneous story lines with multiple pronouns and referential relationships cohesively embedded. All subjects expressed at least some story content, but only the right hemidecorticate narratives conveyed suggestion and implication as well as explicit statement. 相似文献

Three students with autism were taught to self-manage a DRO program to reduce their disruptive behavior. During baseline conditions, all students showed high rates of disruptive behavior (either out-of-seat or nail-flicking). Students were taught to self-manage a DRO program during external reinforcement and prompted self-management conditions. Student gains were maintained during unprompted self-management and follow-up conditions. ©1997 John Wiley & Sons, Ltd. 相似文献

One of the aspects of autism that is often held up as a hallmark of the disorder is a desire for sameness. Students with autism often show a marked lack of variability in language and play skills. The same behavioral patterns are repeated perseveratively, rather than attempting new patterns. In the current study, students diagnosed with autism were taught to self‐manage varied responding. Using a multiple baseline design, three children with autism were taught to self‐monitor and then to self‐manage in order to increase variability in play and social language. All three students demonstrated marked increases in variability during self‐management phases. These gains were maintained at one month follow‐up. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

In a series of experiments, we examined how rate normalization in speech perception is influenced by segments that occur after the target. Perception of the syllable-initial target was influenced by the durations of both the adjacent vowel and the segment after the vowel, even when the identity of the talker was changed during the syllable. These results, together with earlier findings of a temporal window that follows a target phoneme within which segment duration influences perception of the target, help to resolve apparently conflicting results that have been reported previously. Overall, the results fit within a theoretical framework in which the rate at which events take place is extracted early in processing, prior to segregating voices, and the use of this information is obligatory in subsequent processing. 相似文献

The purpose of the study was to determine conditions under which young children enumerate by counting in multiples. Thirty-eight kindergartners and first-graders enumerated dot displays and gave verbal reports of their strategies; additionally, they were given an independent assessment of multiple-counting skill. Dot displays varied according to overall numerosity, perceptual arrangement (random, clustered, rectangular), and numerosity of subgroupings. Children were relatively accurate at enumerating small-numerosity and nonrandom displays. They were relatively likely to report counting by multiples, rather than by ones, on small-numerosity and clustered displays. Contingent upon their skill level, children counted by multiple units (twos, threes, and fours) that corresponded to the numerosity of subgroupings (2, 3, and 4). Contrasting effects of different numerosities and perceptual arrangements are discussed in terms of contextual support for the use, and development, of numerical skills among young children. 相似文献

PAR recognizes teachers and students as co-creators in a learning process that builds self-efficacy essential to long-term educational success. In enabling contexts, PAR projects also allow teachers to critically deconstruct societal power, examine how these dynamics are reproduced in the classroom, and work against the silencing of student voices. This case study describes the process of implementing an inquiry-based PAR model into a formal urban middle school program intended to reduce drop out rates. The anthropologist/researchers employed participant observation, interviews, and review of student work to explore the dynamics, challenges, and constraints confronted during the process. The intervention demonstrated the gap between practice and theory in a middle school environment marked by well-defined hierarchies and roles as well as high-stakes testing. 相似文献

The present study examined the effect of worry versus relaxation and neutral thought activity on both physiological and subjective responding to positive and negative emotional stimuli. Thirty-eight participants with generalized anxiety disorder (GAD) and 35 nonanxious control participants were randomly assigned to engage in worry, relaxation, or neutral inductions prior to sequential exposure to each of four emotion-inducing film clips. The clips were designed to elicit fear, sadness, happiness, and calm emotions. Self reported negative and positive affect was assessed following each induction and exposure, and vagal activity was measured throughout. Results indicate that worry (vs. relaxation) led to reduced vagal tone for the GAD group, as well as higher negative affect levels for both groups. Additionally, prior worry resulted in less physiological and subjective responding to the fearful film clip, and reduced negative affect in response to the sad clip. This suggests that worry may facilitate avoidance of processing negative emotions by way of preventing a negative emotional contrast. Implications for the role of worry in emotion avoidance are discussed. 相似文献
