Discrete trial teaching (DTT) is a systematic form of intervention commonly implemented with children and adolescents diagnosed with autism spectrum disorder. Experimenters and clinicians have implemented DTT in both one‐to‐one instructional formats and group instructional formats to teach a wide variety of skills to children and adolescents diagnosed with autism spectrum disorder. The purpose of this study was to compare DTT implemented in a one‐to‐one instructional format with DTT implemented in a group instructional format in order to determine which format was more effective, efficient, resulted in higher observational learning, and resulted in better maintenance when teaching a variety of expressive skills. The experimenters utilized a parallel treatment design, and the results indicated that both instructional formats were equally effective, there were mixed results in terms of maintenance and efficiency, and group instruction resulted in observational learning.

People have the ability to attentively select and successfully track several moving objects, a process known as multiple-object tracking (MOT; Pylyshyn & Storm Spatial Vision 3: 179–197, 1988). Various factors have been known to influence MOT performance, such as speed, number of distractors, and proximity, while recent work has suggested that object trajectories may also be a factor (Fencsik, Kleiger, & Horowitz Perception and Psychophysics 69: 567–577, 2007). Meanwhile, unexpected changes in motion information have been demonstrated to be a critical facet for attracting attention Howard & Holcombe Attention, Perception & Psychophysics 72: 2087–2095, (2010). Therefore, we suggest that unexpected changes in target trajectories are an important factor in tracking performance. The research presented here controlled for spatial proximity while manipulating the number of instances in which an object changed trajectory. We found that spatial proximity had no effect on tracking performance but, rather, as the number of trajectory changes increased, tracking performance suffered. Results imply that the ability to track multiple moving objects is limited by unexpected changes in direction. 相似文献

In visual search, observers make decisions about the presence or absence of a target based on their perception of a target during search. The present study investigated whether decisions can be based on observers’ expectation rather than perception of a target. In Experiment 1, participants were allowed to make target-present responses by clicking on the target or, if the target was not perceived, a target-present button. Participants used the target-present button option more frequently in difficult search trials and when target prevalence was high. Experiment 2 and 3 employed a difficult search task that encouraged the use of prevalence-based decisions. Target presence was reported faster when target prevalence was high, indicating that decisions were, in part, cognitive, and not strictly perceptual. A similar pattern of responses were made even when no targets appeared in the search (Experiment 3). The implication of these prevalence-based decisions for visual search models is discussed. 相似文献

ABSTRACTPatients who have been attended to at psychiatric institutions sometimes fail to keep their scheduled appointments. This study was designed to assess the extent and determinants of missed first clinic appointments among recently discharged patients with schizophrenia. A total of 311 inpatients with a diagnosis of schizophrenia were participated in the study. The diagnosis of schizophrenia was confirmed using Munich version of the Composite International Diagnostic Interview. Socio-demographic and clinical data were collected using the socio-demographic questionnaire while analysis was done using SPSS (version 16). The rate of missed first outpatient appointment was found to be 25.7%. Missed appointment was associated with male gender, state of origin outside the study site, long distance from hospital to place of abode, longer appointment duration and illness severity at discharge. The findings in this study support the need for the introduction of community psychiatric services to improve patient access to services in Nigeria. 相似文献

ObjectivesThe objective of this study is to report on the development of an instrument to assess non-physical aspects of physical activity (PA)-related self-worth (SW).MethodsThree hundred thirty five women (mean age = 36.69 ± 15.94 yrs, BMI = 24.87 ± 4.56) completed the Women's Physical Activity Self-Worth Inventory (WPASWI), General SW Scale, and a PA Questionnaire. Rasch analysis was used to evaluate the WPASWI.ResultsThree PA-related SW subscales were identified: PA Knowledge (16 items), PA Emotional (13 items), and PA Social (8 items). Rasch analysis supported construct validity, and items demonstrated acceptable internal consistency (Cronbach's alpha = 0.90, 0.87 and 0.72) and test-re-test reliability (r = 0.79, 0.70, 0.81). Women who reported regular PA participation had higher PA Knowledge, PA Emotional, PA Social, and General SW than those who reported some or no PA (p < 0.01) and correlations between Knowledge, Emotional, and Social SW subscales and General SW were 0.207, 0.130, and 0.220, respectively. PA Knowledge and PA Emotional SW had stronger correlations with PA (r = 0.344, 0.273, respectively) than did General SW (r = 0.133).ConclusionsThe WPASWI demonstrated good internal consistency, reliability, construct validity and a stronger relationship with PA than a General SW instrument. 相似文献

Using an abbreviated version of content scales derived by a rational-theoretical approach to the MMPI item pool rather than the traditional criterion group approach, this report demonstrates both satisfactory long- short-form correlations and promising internal consistency for these short-form scales. Comparing women discharged from a psychiatric hospital (N = 40) and non-psychiatric controls (N = 41), these content scales differentiate the two groups both at the beginning of an aftercare intervention study and approximately 20 months later. Mood scales are somewhat less stable over time, especially among patients. While not correlated with age or verbal intelligence, several scales are correlated with measures of social status. 相似文献

Cross Racial Identity Scale (CRIS) Scores: Stability and Relationships With Psychological Adjustment

A humor test composed of cartoons, comic strips, and jokes was administered to 30 college couples (26 single, 4 married) who rated them for humor. Subjects also stated how much they loved and liked their partner, their probability of marrying the partner, and filled out Rubin's Liking and Love Scales. The hypotheses were that similarity of rating of the humorous stimuli would be associated with loving, liking, and predisposition to marry. Hypotheses were confirmed. 相似文献

This brief report explores the external correlates of 2 higher order structures of the Personality Assessment Inventory (PAI; Morey, 1991, 2007); Hoelzle and Meyer's (2009a, 2009b) PAI Components and Hopwood and Moser's (2011) Internalizing and Externalizing Dimensions. Scores from these higher order structures were correlated with life-event data including education, marital status, employment, suicide attempts, psychiatric hospitalizations, trauma, medical problems, hallucinations, paranoid ideation, drug abuse, alcohol abuse, and arrest. Although some differences were noted, the results showed that both Hoelzle and Meyer's Components and Hopwood and Moser's Dimensions were meaningfully correlated with a wide range of life outcomes in a conceptually consistent manner. Overall, these findings provide support for the utility of these higher order variables. 相似文献

The standard view in epistemology is that propositional knowledge entails belief. Positive arguments are seldom given for this entailment thesis, however; instead, its truth is typically assumed. Against the entailment thesis, Myers-Schulz and Schwitzgebel (Noûs, forthcoming) report that a non-trivial percentage of people think that there can be propositional knowledge without belief. In this paper, we add further fuel to the fire, presenting the results of four new studies. Based on our results, we argue that the entailment thesis does not deserve the default status that it is typically granted. We conclude by considering the alternative account of knowledge that Myers-Schulz and Schwitzgebel propose to explain their results, arguing that it does not explain ours. In its place we offer a different explanation of both sets of findings—the conviction account, according to which belief, but not knowledge, requires mental assent. 相似文献
