Echoics are a critical target of language intervention for children with autism, because a well‐established echoic repertoire on the part of the child allows the clinician to use vocal modeling as a flexible, low‐effort prompting procedure during teaching. In this study, we implemented a chaining procedure to increase the complexity of echoics in 2 children with autism and 1 child with developmental delay. The procedure was effective for all 3 participants, and gains were maintained after treatment was withdrawn in most cases. 相似文献

Participants were pretrained and tested on mutually entailed trigonometric relations and combinatorially entailed relations as they pertained to positive and negative forms of sine, cosine, secant, and cosecant. Experiment 1 focused on training and testing transformations of these mathematical functions in terms of amplitude and frequency followed by tests of novel relations. Experiment 2 addressed training in accordance with frames of coordination (same as) and frames of opposition (reciprocal of) followed by more tests of novel relations. All assessments of derived and novel formula‐to‐graph relations, including reciprocal functions with diversified amplitude and frequency transformations, indicated that all 4 participants demonstrated substantial improvement in their ability to identify increasingly complex trigonometric formula‐to‐graph relations pertaining to same as and reciprocal of to establish mathematically complex repertoires. 相似文献

Do the laws of nature supervene on ordinary, non‐nomic matters of fact? Lange’s criticism of Humean supervenience (HS) plays a key role in his account of natural laws. Though we are sympathetic to his account, we remain unconvinced by his criticism. We focus on his thought experiment involving a world containing nothing but a lone proton and argue that it does not cast sufficient doubt on HS. In addition, we express some concern about locating the lawmakers in an ontology of primitive subjunctive facts and suggest that a ‘mixed’ metaphysics to the lawmaker question might be attractive. 相似文献

ObjectivesThe objectives of this research were a) to explore the applicability of ‘motivational climate’ research to early career athletes under the age of twelve, b) to re-examine the concept of ‘motivational climate’ in the light of recent scientific developments, and c) to concurrently study the influences of coaches, parents and peers on athletic motivation.Design and MethodUsing a qualitative design, 40 participants (7–11 years of age) from various sports were interviewed in focus groups, using a semi-structured format to investigate the roles played by coaches, parents, and peers in influencing athlete motivation. An inductive content analysis was conducted to determine which behaviours among these social agents influenced key motivational outcomes.FindingsThe analysis indicated that young athletes experience a motivational climate which shows consistencies with existing models of motivation; suggesting this population is worthy of further study. The influences of coaches related most strongly to the manner in which they perform their roles of instruction and assessment, whereas parents' influences were most salient in terms of the way they support the child's participation and learning. Both parents and coaches exerted influences through their leadership styles, affective responses and pre-performance behaviours. Peers influenced participants' motivation through competitive behaviours, collaborative behaviours, evaluative communications and through their social relationships.ConclusionsThis study provides an insight into the motivational climate experienced by young athletes and helps to delineate the different roles of social agents in influencing their motivation at this early stage of development. 相似文献

A central feature of many formal accounts of reading aloud, and of Coltheart and colleagues dual-route cascaded model in particular, is that activation across various modules is cascaded. Evidence is reviewed that this assumption is problematic in a particular context, along with a solution that involves thresholding the output of the letter level to the nonlexical routine. Consideration of the known effects of repetition leads to the prediction of a three-way interaction between stimulus quality, repetition, and lexicality in which repetition and stimulus quality interact when reading aloud exception words, but produce additive effects when reading aloud nonwords. The result of such an experiment confirms this prediction, and appears consistent with the localized dual-route model. Implications for other accounts are briefly noted. 相似文献

This research examined the associations between measures of sociotropic and autonomous personality, romantic attachment anxiety and avoidance, and corresponding attachment ratings across a range of different specific relationships with people whom participants regularly interacted (including romantic partners, friends, family members, and colleagues). Analyses using hierarchical linear modeling showed that sociotropy and autonomy were directly associated with respective ratings of relationship-specific anxiety and avoidance within non-romantic relationships. In contrast, domain-specific romantic attachment predicted relationship-specific attachment with romantic (but not non-romantic) partners, and, as hypothesized, mediated the associations between sociotropy and autonomy and relationship-specific attachment within this domain. Implications for the operationalization of sociotropy and autonomy as broad-bandwidth (personality-level) measures that assess more global summaries of regularities in the same dual dimensions identified in the attachment literature (i.e., attachment anxiety and avoidance) are discussed. 相似文献

Effects of agency on movement interference during observation of a moving dot stimulus 总被引:1,自引:0,他引:1
Stanley J Gowen E Miall RC 《Journal of experimental psychology. Human perception and performance》2007,33(4):915-926
Human movement performance is subject to interference if the performer simultaneously observes an incongruent action. It has been proposed that this phenomenon is due to motor contagion during simultaneous movement performance-observation, with coactivation of shared action performance and action observation circuitry in the premotor cortex. The present experiments compared the interference effect during observation of a moving person with observation of moving dot stimuli: The dot display followed either a biologically plausible or implausible velocity profile. Interference effects due to dot observation were present for both biological and nonbiological velocity profiles when the participants were informed that they were observing prerecorded human movement and were absent when the dot motion was described as computer generated. These results suggest that the observer's belief regarding the origin of the dot motion (human-computer generated) modulates the processing of the dot movement stimuli on their later integration within the motor system, such that the belief regarding their biological origin is a more important determinant of interference effects than the stimulus kinematics. 相似文献
