Two studies were conducted that examined the preference of a student diagnosed with a brain injury. In Study 1, a preference assessment was followed by a three-choice concurrent-operants reinforcer assessment. Two choices resulted in access to preferred activities for completing work, and a third choice resulted in access to nothing (i.e., no activity). Unpredictably, the participant consistently chose the no-activity option. Study 2 examined why this student preferred work associated with no activity over preferred activities. Through a variety of concurrent-operants procedures, it was determined that she preferred fluent work followed by reinforcers rather than work that was broken up by access to preferred activities. Implications for research on preference are discussed.  相似文献

Maternal vocal imitation of infant vocalizations is highly prevalent during face-to-face interactions of infants and their caregivers. Although maternal vocal imitation has been associated with later verbal development, its potentially reinforcing effect on infant vocalizations has not been explored experimentally. This study examined the reinforcing effect of maternal vocal imitation of infant vocalizations using a reversal probe BAB design. Eleven 3- to 8-month-old infants at high risk for developmental delays experienced contingent maternal vocal imitation during reinforcement conditions. Differential reinforcement of other behavior served as the control condition. The behavior of 10 infants showed evidence of a reinforcement effect. Results indicated that vocal imitations can serve to reinforce early infant vocalizations.  相似文献

Clinicians are particularly challenged by the development of interventions for behavior maintained by automatic reinforcement because reinforcers that maintain the responses often cannot be directly observed or manipulated. Researchers have conducted either preference assessments or competing items assessments when developing effective treatments for behavior maintained by automatic reinforcement. However, interventions based on these assessments have not been directly compared. The current study evaluated procedures to make such a comparison. High-competition items resulted in greater reductions in vocal stereotypy than did high-preference items for a preschool boy with autism.  相似文献

Abstract: According to an orthodox account of meaning and translation, meaning is a property of expressions of a language, and translation is a matching of synonymous expressions across languages. This linguistic account of translation gives rise to well‐known skeptical conclusions about translation, objectivity, meaning, and truth, but it does not conform to our best translational practices. In contrast, I argue for a textual account of meaning based on the concept of a text‐type that does conform to our best translational practices. With their semantic function in view, text‐types are Archimedean points for their respective disciplines. The text‐type of philosophy is no exception. Culture‐transcendent conceptual analysis can proceed on firm footing without having to deny the reality of radical cultural and linguistic difference by treating components of text‐types as the concepts to be analyzed. Analyses of central philosophical concepts are provided as a means of adjudicating philosophical controversy.  相似文献

A confirmatory factor analysis was conducted examining the higher order factor structure of the WISC-IV scores for 344 children who participated in neuropsychological evaluations at a large children's hospital. The WISC-IV factor structure mirrored that of the standardization sample. The second order general intelligence factor (g) accounted for the largest proportion of variance in the first-order latent factors and in the individual subtests, especially for the working memory index. The first-order processing speed factor exhibited the most unique variance beyond the influence of g. The results suggest that clinicians should not ignore the contribution of g when interpreting the first-order factors.  相似文献

The Scenario-based Performance Observation Tool for Learning In Team Environments (SPOTLITE) provides a systematic method for developing team performance measurement instruments comprised of behaviorally anchored rating scales that are tied to observable behaviors that tap critical knowledge and skills and can be assessed at specific intervals during a training scenario. We developed a measurement instrument for four-person teams of F-16 pilots training for air-to-air combat in a high-fidelity simulation environment and implemented it in a handheld computer to support fast and accurate data entry as a team executes a scenario. An experiment demonstrated the sensitivity, reliability, and validity of the instrument.  相似文献

Evidence-based practice, the rigorous conduct of clinical analysis and intervention, includes practice-based evidence. Here, practice data were the source of three “clinical portraits” used for exploratory analysis of an array of cognitive and social problems in 30 children whose neurobehavioral profiles fulfilled psychometric criteria for a nonverbal learning disability (NLD). Qualitative analysis of the children's academic and adjustment difficulties revealed patterns of dissociable deficits. These findings argue for at least three groups within the NLD construct. Identifying such subgroups is of practical importance: More precise characterization of neuropsychological competencies leads to improved interventions and better outcomes.  相似文献

Aims: The present study investigates beliefs, attitudes and practices of 101 monolingual and multilingual therapists in their interactions with multilingual patients. Method: A mixed‐method approach was adopted using an online questionnaire with closed questions, and informed questions in interviews with one monolingual and two multilingual therapists. Results: A principal component analysis yielded a four‐factor solution accounting for 41% of the variance. The first dimension, which explained 17% of variance, reflects therapists' attunement towards their bilingual patients (attunement versus collusion). Further analysis showed that the 18 monolingual therapists differed significantly from their 83 bi‐ or multilingual peers on this dimension. The follow‐up interviews confirmed this result. Discussion: Recommendations based on these findings are made for psychotherapy training and supervision.  相似文献
