The errors and error detections made by qualified and trainee typists were examined, when they were given a passage of prose that included pseudo-words and words made up of random consonants. It was shown that trainees make more and detect relatively fewer errors. For all typists errors are made more often per letter in long or degraded words and are relatively less likely to be detected. 相似文献

Maximizing the discriminating power of a multiple-score test involves maximizing the homogeneity of each subtest and minimizing the correlations between subtests. A method is presented for constructing such tests from items whose intercorrelations are not too high. Under certain restrictions the saturation, defined as the proportion of inter-item covariance to total variance, is maximized for each subtest. The nucleus of each subtest is three items with high covariancesinter se. All items which will lower the saturation are discarded; the one item is added which will maximize the saturation of the resultant test. This process is repeated until all the items are included or discarded for that subtest. If the correlation between any such subtests approaches the geometric mean of their saturations, their items form a new pool for one or more subtests. Formulas are presented for deciding which items to eliminate in order to reduce further the correlations between subtests.This research was supported in part by the United States Air Force under Contract AF 33(038)-10588 with Human Resources Research Center, Lackland Air Force Base, San Antonio, Texas.

This study examined the effects of similarity between the processing of acquisition and the processing of test materials on performance in a problem solving task. Previous work by Perfetto, Bransford, and Franks (1983) demonstrated that uninformed subjects’ failure to utilize relevant acquisition information in a later problem solving task is the result of a failure to spontaneously access such information. The present study demonstrated that spontaneous access can be enhanced when both acquisition and test materials are processed in a similar manner, that is, in a problem-oriented manner. Furthermore, the present findings indicate that the processing similarity leading to enhanced access is specific to particular acquisition and test items, rather than a general problem solving set induced at acquisition and the subsequent testing situation. Results are interpreted within a transfer-appropriate processing perspective. 相似文献

Tye claims that an externalist should say that memory content invoking natural kind concepts floats free of the setting where the memory is laid down and is at later times determined by the context in which the memory is revived. His argument assumes the existence of 'slow switching' of the meaning of natural kind terms when a person is transported from Earth to Twin Earth. But proper understanding of natural kind terms suggests that slow switching (contrary to what is often presupposed) is likely never to be completed. Hence the situation of a person unknowingly transported to Twin Earth is not that his memories switch content but rather than he gets two natural kinds confused. 相似文献

In today’s climate, with the ever-increasing demand for competent behavior analytic services, it is necessary for behavior analysts to work across a variety of settings, including home, school, and community, overseeing instructional aide staff as the frontline providers of applied behavior analysis (ABA) services. It is common practice for ABA practitioners to provide the supervision and training to parents, caregivers, and direct-care staff, who may have limited knowledge and experience within the field of ABA. In 2013, the Behavior Analysis Certification Board (BACB®) initiated an effort to establish standards for the training of instructional aides and direct-care staff in the delivery of instructional and treatment services based on the principles of ABA. This new standard and credential is known as a Registered Behavior Technician? (RBT®). The purpose of this study was to evaluate the training process outlined by the BACB, focusing specifically on the generalizability and long-term maintenance of newly acquired skills taught through a competency-based approach, to novel opportunities for implementation. Training was conducted through two methods: in vivo training with clients versus role-play with peers. Both these types of staff training approaches are commonly used instructional practices in the field of ABA. 相似文献

Observation is the ‘gold standard’ for assessing parent-child behavior, however few studies have compared coding live, in real time, versus coding from videotapes in terms of their achievable levels of coder reliability within the field of parent programme research. This is important for practitioners and researchers for whom decisions might be influenced by time and financial constraints, but where outcomes may have real practical and clinical implications. Trained coders in the Dyadic Parent-Child Interaction Coding System Revised, coded 40 half-hour videotapes of 33 parent-toddler dyads interacting in the home on 29 items of dyadic behaviour. Four theorised composite variables were constructed. Videotaped data were compared to data drawn from the same interactions previously coded ‘live’ in the home. Correlations indicated significant agreement between the two modes at the item by item level (p?<?.001). Wilcoxon Rank tests revealed significant differences (p?<?.001) between the two modes. Eight items exceeded a ±30% change in median score suggesting clinically relevant differences. Although both methods achieved acceptable levels of inter-rater reliability, video coding achieved higher levels of agreement. Subtle differences exist between the two modes. Whilst neither mode proved superior it is suggested that they should not be used interchangeably. 相似文献
