Four experiments examined the hypothesis that the Valins (1966) false physiological feedback effect with attractiveness ratings of slides is due to experimenter demand. Experiments 1 and 2 showed significant feedback effects with 5-sec feedback periods, previously reported by Barefoot and Straub (1971) to be too brief a time to search the slides for a cause of the apparent physiological arousal. Experiments 3 and 4 had 17 variations of instructions (emotional, nonemotional), stimuli (slides of people, scenic tourist slides), and type of feedback information (heart rate, eyeblink, or none). The typical false feedback effect was found under many conditions that did not seem to meet the presumptive attributional requirements for the effect. In Experiment 4, only subjects who said they were supposed to rate feedback slides higher showed the effect, regardless of instructions, stimuli, or type of feedback. The overall results are interpreted in terms of experimenter demand and stimulus salience effects.  相似文献

Comparisons are made between BILOG version 2.2 and LOGIST 5.0 Version 2.5 in estimating the item parameters, traits, item characteristic functions (ICFs), and test characteristic functions (TCFs) for the three-parameter logistic model. Data analyzed are simulated item responses for 1000 simulees and one 10-item test, four 20-item tests, and four 40-item tests. LOGIST usually was faster than BILOG in producing maximum likelihood estimates. BILOG almost always produced more accurate estimates of individual item parameters. In estimating ICFs and TCFs BILOG was more accurate for the 10-item test, and the two programs were about equally accurate for the 20- and 40-item tests.I am grateful to Robert J. Mislevy, Martha L. Stocking, and Marilyn S. Wingersky for many helpful comments on an earlier version of this paper. I would also like to thank Hamid Kamrani and Bongmyoung Park for getting LOGIST and BILOG running and keeping them running under changing computer systems at CTB/McGraw-Hill.  相似文献

In this two-experiment investigation, the long-term (at least 6 months) employment of 51 moderately mentally retarded clients who were placed into 64 supported employment positions was first evaluated relative to 10 training and posttraining components that comprised a supported employment training package. In Experiment 1, chi-square analyses were used to identify three components that differentiated successful (employed for at least 6 months) from unsuccessful clients. In Experiment 2, 4 successful clients were further evaluated in a nonconcurrent multiple baseline design to determine whether the three variables identified during the group analysis (client advocate, collateral behavior, and follow-up plan) were included in the training packages. These results are discussed in terms of the need to establish better the functional variables of supported employment training programs.  相似文献

This investigation presents a cost-benefit analysis completed for one of 27 states implementing supported employment as a result of federal funding. Based upon the benefits and costs detailed, society realized a $0.75 return for every $1.00 invested in supported employment in Illinois. Supported employees realized a 37% increase in their earnings over a comparable period. The results of this study are discussed and recommendations are made for similar analyses across states.  相似文献

Similar structured diagnostic interviews about the child were given by different interviewers to a cohort of 307 mother-child pairs. A diagnosis was made by computer on each interview, using specified criteria. Diagnoses on mother-child interviews were compared using the kappa statistic. Kappas of .30 or higher were found for the diagnosis of antisocial personality, conduct disorder, enuresis, mixed behavior-neurotic disorder, and possible depression. Comparisons were made for sex and age. Possible depression and enuresis were diagnosed reliably at all age levels and for both sexes. The limitations of the interview and diagnostic system used are discussed. The findings support the need for further efforts to develop diagnostic research interviews for use with children and adolescents.  相似文献

Genetic counselors and clinical geneticists are often in the position of delivering difficult news (DDN) to patients and families. Many studies show that healthcare providers require major improvement in the skills needed in DDN in a manner that is satisfactory to their patients. The purpose of this study was to assess the amount and methodology of DDN training received by genetic counselors and medical genetics residents in their training programs, such as observations of DDN or attending didactic lectures. To our knowledge, there is no previous assessment or study of DDN training in genetic counselor and medical genetics residency programs; therefore, we aim to both assess and compare the training in DDN received by genetic counselors and by genetics residents and determine whether there is a desire for recommendations on DDN training. We invited genetic counseling (GC) and genetics residency program directors to participate in an online survey designed to assess coursework, clinical experiences, and directors’ attitudes toward teaching DDN. Response rate was 85% (28/33) for GC program directors and 26% (14/53) for genetics residency program directors. One hundred percent of GC and genetics residency directors who responded to the survey agreed that it is important for genetic counselors and medical geneticists to be able to deliver difficult news effectively and that training programs should formally teach students how to deliver difficult news. Six of the eight common teaching methods are used by at least 75% of GC programs while two of eight are used by at least 75% of genetics residency programs. Seventy-nine percent of GC and 93% of genetics residency program directors agree that there should be recommendations on how to teach students to deliver this news. Our results show that techniques for DDN are integrated more fully into GC program curricula than genetics residency curricula. Directors of both types of programs desire recommendations and more standardized education for training students to deliver difficult news.  相似文献

Joint attention is a pivotal social communication skill often absent or impaired in young children with autism spectrum disorder. Joint attention is the shared and alternating attention of two individuals on an object or event, and has implications for later communication and social communication skills. This study used a concurrent multiple‐baseline design across 3 caregiver–child dyads to train caregivers to teach response to joint attention behaviors to their 3–6 years old children with moderate to severe autism spectrum disorder. Caregivers were trained on strategies including prompting, time delay, and elements of naturalistic teaching and implemented the intervention in brief 10‐min sessions 2–3 times per week. Results indicate parent mastery of intervention and substantial increase in child response to joint attention behaviors both prompted and independent. Implications for practice and areas for future research are discussed.  相似文献
