Some individuals with intellectual disabilities do not respond to praise as a reinforcer, which may limit their ability to learn. We evaluated 2 procedures (stimulus pairing and response—stimulus pairing), both of which involved pairing previously neutral praise statements with preferred edible items, to determine their usefulness in establishing praise as a reinforcer. Results of Study 1 indicated that stimulus pairing was not effective in conditioning praise as a reinforcer for 3 of 4 subjects; results were inconclusive for the 4th subject. Results of Study 2 indicated that response—stimulus pairing was effective in conditioning praise as a reinforcer for 4 of 8 subjects. After conditioning, praise also increased the occurrence of additional target responses for these 4 subjects. 相似文献

Some research indicates that trauma history might be related to nonsuicidal self-injury (NSSI), but the exact nature of this relationship is unknown. Therefore, we created and tested a structural equation model for the relationships between composite trauma, NSSI, mental health diagnosis, and gender in a community sample of 296 U.S. adults recruited through Amazon Mechanical Turk. Composite trauma and mental health diagnosis were significantly predictive of an NSSI history. The pathway between NSSI and gender was not significant. It is important to consider multiple domains of trauma, in the form of composite lifetime trauma, as risk factors for NSSI. 相似文献

As humans age, the amount of intra-individual variability (IIV) present in both their gait and their cognitive performance tends to increase. Both gait and cognitive IIV are associated with attentional control and with cerebrovascular disease, suggesting that the IIV in gait and cognitive function should be strongly correlated in the elderly. In this study temporal gait variability was determined from a 60-second period of walking. Cognitive variability was determined from two decision-time tasks assessing inhibition. Despite the presence of substantial amounts of gait and cognitive IIV in 71 elderly individuals, there were no significant correlations between measures of cognitive and gait IIV, suggesting that different factors drive IIV in the motor and cognitive performance of older individuals. These results are not consistent with the common cause theory of aging, which predicts that cognitive and sensorimotor performance should show related declines due to age-related disruption of a common neurological substrate. 相似文献

Four studies created malingering and response bias scales for a new test battery, the Attachment and Clinical Issues Questionnaire (ACIQ). In the first calibration study, a new approach to identifying fake good and fake bad respondents was outlined. In Study 2, this scale was cross validated in a within-subjects design that also found only weak correlations between the scales of the ACIQ and measures of social desirability. The third study developed a method violator scale (one who responds randomly to the content of the scales due to carelessness, low IQ, etc.). It was tested by Monte Carlo and empirical studies. The fourth study combined the two cross validation studies to offer clear cutoffs for the practitioner. These studies successfully led to the creation of malingering and response bias scales for the ACIQ and also introduced new methods that could be adapted to other instruments. 相似文献

A functional analysis is a valuable assessment technique that requires a unique kind of precision on behalf of the therapist. However, there is a lack of empirically validated tools for training functional analysis skills. This study examined the effectiveness of an instructional DVD in training college students to perform five functional analysis conditions. During simulated sessions, participants acted as therapists, and observers measured the accuracy with which they implemented programmed antecedents and consequences. Results showed that the DVD was effective in improving all participants' accuracy above baseline levels; however, in order to meet the 90% performance criterion, all participants required feedback. These results suggest that an instructional video is a useful training tool in providing basic skills for conducting functional analyses. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Although emotional dysfunction is an important aspect of major depressive disorder (MDD), it has rarely been studied in daily life. Peeters, Nicolson, Berkhof, Delespaul, and deVries (2003) observed a surprising mood-brightening effect when individuals with MDD reported greater reactivity to positive events. To better understand this phenomenon, we conducted a multimethod assessment of emotional reactivity to daily life events, obtaining detailed reports of appraisals and event characteristics using the experience-sampling method and the Day Reconstruction Method (Kahneman, Krueger, Schkade, Schwarz, & Stone, 2004) in 35 individuals currently experiencing a major depressive episode, 26 in a minor depressive (mD) episode, and 38 never-depressed healthy controls. Relative to healthy controls, both mood-disordered groups reported greater daily negative affect and lower positive affect and reported events as less pleasant, more unpleasant, and more stressful. Importantly, MDD and mD individuals reported greater reductions in negative affect following positive events, an effect that converged across assessment methods and was not explained by differences in prevailing affect, event appraisals, or medications. Implications of this curious mood-brightening effect are discussed. 相似文献

It has been suggested that verbally sophisticated individuals engage in a series of precurrent behaviors (e.g., covert intraverbal behavior, grouping stimuli, visual imagining) to solve problems such as answering questions (Palmer, 1991; Skinner, 1953). We examined the effects of one problem solving strategy--visual imagining--on increasing responses to intraverbal categorization questions. Participants were 4 typically developing preschoolers between the ages of 4 and 5 years. Visual imagining training was insufficient to produce a substantial increase in target responses. It was not until the children were prompted to use the visual imagining strategy that a large and immediate increase in the number of target responses was observed. The number of prompts did not decrease until the children were given a rule describing the use of the visual imagining strategy. Within-session response patterns indicated that none of the children used visual imagining prior to being prompted to do so and that use of the strategy continued after introduction of the rule. These results were consistent for 3 of 4 children. Within-session response patterns suggested that the 4th child occasionally imagined when prompted to do so, but the gains were not maintained. The results are discussed in terms of Skinner's analysis of problem solving and the development of visual imagining. 相似文献
