Brief experimental analyses (BEA) have been used to identify effective individualized interventions for improving reading
fluency with school-age children. Interventions involving incentives, modeling, repeated reading, and error correction are
most often tested in a BEA. However, these interventions are rarely modified according to individual student needs. The current
study examined the effects of varied levels of modeling (passage, sentence, word) and varied contingencies (tracking and fluency)
on fluency in non-treated high-word overlap passages and general outcome measure passages. BEA-identified interventions were
effective for improving reading fluency on non-treated passages for both second grade students and the third grade student.
Notably, the effects reversed when intervention was withdrawn with one of the second grade students. Results are discussed
in terms of considerations in the application of BEA technology in the schools. 相似文献

Male Sprague Dawley rats were allowed to self-administer cocaine (0.5 mg/kg) during 90 min sessions for a period of 15 days. On day 16, rats were either held abstinent in their home cage environment or experienced an extinction session in which the active lever had no programmed consequences. Facilitating N-methyl-d-aspartate (NMDA) receptor activity with the coagonist d-serine (100 mg/kg i.p.) before or following the extinction session significantly reduced the subsequent cocaine-primed reinstatement of drug-seeking behavior tested on day 17. d-Serine significantly reduced drug-primed reinstatement only when combined with extinction, and its effectiveness when administered following the training session suggested that an enhancement of consolidation of extinction learning had occurred. In contrast, d-serine treatment did not reduce sucrose-primed reinstatement, indicating that the beneficial effects of this adjunct pharmacotherapy with extinction training were specific to an addictive substance (cocaine) and did not generalize to a natural reward (sucrose). 相似文献

Personality and the coherence of psychotherapy narratives 总被引:2,自引:0,他引:2

The stories people construct about themselves and their social worlds are key aspects of their identities [Bruner, J. S. (1990). Acts of meaning. Cambridge, MA: Harvard University Press; McAdams, D. P. (2001). The psychology of life stories. Review of General Psychology, 5, 100–122]. Whereas certain expected life experiences (e.g., leaving home, getting a job) may be relatively easy to narrate, more unexpected and difficult events, such as undergoing psychotherapy, may pose a challenge to successful narration. Yet it is especially important to successfully narrate one’s experience in psychotherapy in order to maintain the gains from treatment [Frank, J. D. (1961). Persuasion and healing: A comprehensive study of psychotherapy. Baltimore, MD: Johns Hopkins University Press; Spence, D. P. (1982). Narrative truth and historical truth: Meaning and interpretation in psychoanalysis. New York: W.W. Norton]. The present study collected psychotherapy narratives from 76 adult former clients and coded them for the fundamental story criterion of coherence [Baerger, D. R., & McAdams, D. P. (1999). Life story coherence and its relation to psychological well-being. Narrative Inquiry, 9, 69–96]. Former clients that were high in trait Openness to experience and those at higher stages of ego development told more coherent stories about therapy. The relationship between ego development and narrative coherence remained significant even when controlling for Openness. The findings suggest that high ego development may provide narrators with the kind of sophisticated frameworks for meaning-making that are especially well-suited for the important task of making good sense of psychotherapy. 相似文献

In two experiments, we investigated the morphosyntactic decomposition and semantic composition of acoustically presented German compound words. A left-anterior negativity (LAN) was found in the ERP for gender incongruent, initial compound constituents although these constituents are syntactically irrelevant in German. This LAN provides online evidence for morphosyntactic decomposition. Experiment 1 showed also preliminary evidence for semantic composition, which was further investigated in Experiment 2 by comparing semantically transparent and opaque compounds. Transparent compounds elicited an increased negativity with a centroparietal maximum that occurred during the presentation of the head constituent. This negativity is suggested to reflect the semantic integration of compound constituents that is necessary after the constituents have been accessed separately. 相似文献

Movement activity of a normal baboon and of a baboon with induced Parkinsonism by unilateral administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was recorded by the Walter Reed Activity Monitor (or actigraph). Mean activity in the lesioned baboon was 41% less than that of the nonlesioned baboon measured over a 14-day period. In addition, the daily maximum activity value was significantly less in the MPTP-treated baboon. Moreover, resting and sleeping periods were 30% greater in the lesioned animal. The akinesia and resting and sleeping periods were displayed by the lesioned baboon throughout the day, whereas the control baboon showed them only at night. The data representing summarized movement activity are in accordance with observations of bradykinesia, hypokinesia, and akinesia of the MPTP-treated baboon. The actigraph was well tolerated by the animal because its small size and weight made it largely unobtrusive. We suggest that the actigraph is an appropriate device for measuring motor activity in nonhuman primates. 相似文献

The purpose of this study was to investigate differences in tactile sensory system function between men and women. This task was accomplished by studying the effects of possible tactile threshold shifts occurring during magnitude-estimation scaling of vibratory stimuli presented to the dorsal surface of the tongue. 12 men (M age = 19.7 yr.) and 12 women (M age = 19.3 yr.) participated. Analysis suggested that men and women have tactile sensory systems that operate similarly at both threshold and suprathreshold levels of stimulation. Men and women do, however, choose to use consistently different numerical responses to suprathreshold stimuli, suggesting that environmental and/or cultural-educational influences may be involved in numerical decision-making aspects of the scaling process. 相似文献

Effects of induced verbal labeling on short-term and incidental memory were studied in Yucatan, Mexico. The 208 subjects, evenly divided by sex, were selected from four age groups (7–8, 10–11, 13–15, 20–21 years) from a large public school. Stimuli were cards depicting both animals and objects familiar to all subjects, and were presented over 14 trials. Short-term memory was tested with a probed serial recall task on each trial; incidental memory was tested following the 14 trials. Several results conformed to findings with earlier studies using American subjects: short-term memory improved with age; primacy and recency recall were influenced by both age and labeling; and the typical inverted U-shaped incidental memory function was found. Verbal labeling apparently aided recall by focusing attention on the relevant items, but such overt labeling also impeded the strategy of verbal rehearsal used by older subjects. Cultural factors appeared to play a limited role in the present study; the common element of formal schooling, among both American and Yucatecan subjects, was hypothesized as a possible explanation of such cross-cultural similarities. 相似文献
