Influences on the perception of affordances (i.e., opportunities for actions) have been primarily studied by manipulating the functional morphology of the body. However, affordances are not just determined by the functional morphology of the perceiver, but also by the physiological state of the perceiver. States of anxiety have been shown to lead to marked changes in individuals' physiological state and their behaviour. To assess the influence of emotional state on affordance perception, the perception of action capabilities in near space was examined after participants completed an anxiety-provoking task. Anxiety was induced immediately prior to tasks that assessed participants' perceived reaching ability in Experiment 1, grasping ability in Experiment 2, and the ability to pass their hands through apertures in Experiment 3. Results indicated that those participants who experienced changes in anxiety underestimated their reaching, grasping, and passing ability compared to non-anxious participants. In other words, anxious participants were more conservative in their estimations of their action capabilities. These results suggest that anxiety influences the perception for affordances in near space and are consistent with the notion that anxiety induces withdrawal behaviours. 相似文献

There is ongoing debate about the methods that evaluators should use to assess the adaptive functioning of an individual in an Atkins claim, including the appropriateness of using self‐report measures and extent to which adaptive functioning measures are valid for persons with a history of violent offending. This study examined whether offenders' self‐report adaptive functioning scores tended to decrease as their level of psychopathic traits increased. Eighty‐five male felony probationers completed the self‐report version of the Adaptive Behavior Assessment System – II (ABAS‐II: Harrison & Oakland, 2003), the Psychopathic Personality Inventory – Revised (PPI‐R: Lilienfeld & Widows, 2005), and a brief intelligence screening measure. ABAS‐II composite scores were negatively correlated with PPI‐R Self‐Centered Impulsivity and Coldheartedness scores, but positively correlated with Fearless Dominance scores. These relationships appeared to be due, in part, to over‐reporting symptoms of impairment across measures, suggesting that scores on self‐report adaptive functioning measures may be especially susceptible to feigning.

We examined psychological functioning in siblings of children with Attention Deficit Hyperactivity Disorder (ADHD). Siblings of children diagnosed with ADHD (n = 45) between the ages of 9 and 13 and a control group (n = 46) within the same age range composed of siblings of children with no diagnosed disorders completed measures of psychological functioning. A significant multivariate difference was observed on these measures across groups. Post hoc investigation of the univariate means revealed one significant group difference, which occurred on a measure of Trait Anger. This finding suggests that future research on family members of children with ADHD may be warranted. 相似文献

Generalization across three stimulus parameters was examined for 5 individuals whose self-injurious behavior was maintained by escape from task demands. Prior to treatment, three stimulus parameters (therapist, setting, and demands) were systematically varied across baseline sessions. These variables were held constant during treatment, which consisted of escape extinction. When treatment was completed, three novel stimulus parameters were probed. If the rate of self-injury was high during this probe, treatment was reimplemented with one new stimulus parameter (the other two were the same as in the original treatment condition). Following this second treatment, another probe with three novel stimuli was conducted. If the rate of self-injury was again high, treatment was implemented again while a second stimulus parameter was changed. This sequence continued until generalization was observed across the three parameters. Results showed idiosyncratic differences in generalization. The behavior of 2 subjects showed complete generalization during the first novel probe. A 3rd subject's behavior showed generalization following treatment across two stimulus parameters (setting and therapist). The behavior of the 2 remaining subjects showed a complete lack of generalization across the three parameters; both subjects required training for novelty by randomly varying the stimulus parameters for a substantial number of sessions. 相似文献

Hand mouthing often has been described as a stereotypic response that is maintained by non-social (automatic) reinforcement; however, data supporting this conclusion can be found in relatively few studies. This series of studies presents an experimental analysis of conditions associated with the maintenance of hand mouthing. In Experiment 1, a functional analysis was conducted for 12 individuals who engaged in chronic hand mouthing to determine whether the behavior is usually maintained independent of social contingencies. Results obtained for 10 subjects were consistent with an automatic reinforcement hypothesis; the remaining 2 subjects' hand mouthing was maintained by social-positive reinforcement. Based on these results, Experiment 2 was designed to identify the specific reinforcing properties of hand mouthing. Each of 4 subjects was provided with a toy that substituted for hand mouthing, and preference for a specific topography of toy manipulation (hand-toy contact or mouth-toy contact) was measured. Results indicated that hand stimulation was the predominant reinforcer for all subjects. Experiment 3 provided an extension of Experiment 2 in that the same responses were measured across a variety of toys presented to each of 5 subjects. Results again indicated that hand stimulation was the predominant reinforcer for all subjects. Implications of these results are discussed with relevance to treatment. 相似文献

In prior research, differential reinforcement of alternative behavior (DRA) has been implemented at optimal treatment values: Problem behavior is never reinforced, and alternative behavior is always reinforced. However, in application, DRA is unlikely to be conducted optimally. In this study, following a functional analysis phase and a differential reinforcement at full implementation phase, we challenged initially positive treatment effects for 3 participants by implementing DRA at less than optimal parameters. For example, some occurrences of problem behavior were reinforced, and some occurrences of alternative behavior were not reinforced. Results suggested that when exposed to DRA at full implementation, participants showed a bias toward appropriate behavior in subsequent conditions during which “mistakes” (treatment challenges) were intentionally introduced. In addition, the negative effects of treatment challenges were quickly reversible, in comparison to the positive effects of DRA, which were not quickly reversible in the face of treatment challenges. 相似文献

To evaluate the effects of environmental enrichment on stereotypic self-injurious behavior (SIB), we conducted an assessment of preference for manipulating alternative stimuli rather than engaging in SIB. First, for each of 3 participants, a functional analysis of SIB was conducted in Phase 1. Participants were selected for Phase 2 if the functional analysis showed that SIB persisted in the absence of social consequences. In Phase 2, a preference assessment was conducted in which participants were observed manipulating preferred stimuli in a free-operant format. A measure was taken of time spent manipulating each stimulus and time spent engaging in SIB. In Phase 3, environmental enrichment was evaluated using stimuli that were preferred over the target response, and alternative treatments were evaluated in the event of environmental enrichment failure. Results suggested that the free-operant preference assessment (a) predicted the efficacy or inefficacy of an environmental enrichment procedure and (b) suggested possible treatment alternatives when environmental enrichment was ineffective. Collectively, the results may provide a basis for interpreting the idiosyncratic effects of environmental enrichment and a rationale for treatment selection when behavioral function is unknown. 相似文献

The current study investigates sudden gains (rapid symptom reduction) in group cognitive-behavioral therapy for panic disorder. Sudden gains occurring after session 2 of treatment predicted overall symptom reduction at treatment termination and some changes in cognitive biases. Meanwhile, sudden gains occurring immediately following session 1 were not associated with symptom reduction or cognitive change. Together, this research points to the importance of examining sudden gains across the entire span of treatment, as well as the potential role of sudden gains in recovery from panic disorder. 相似文献

Consideration of reinforcer magnitude may be important for maximizing the efficacy of treatment for problem behavior. Nonetheless, relatively little is known about children's preferences for different magnitudes of social reinforcement or the extent to which preference is related to differences in reinforcer efficacy. The purpose of the current study was to evaluate the relations among reinforcer magnitude, preference, and efficacy by drawing on the procedures and results of basic experimentation in this area. Three children who engaged in problem behavior that was maintained by social positive reinforcement (attention, access to tangible items) participated. Results indicated that preference for different magnitudes of social reinforcement may predict reinforcer efficacy and that magnitude effects may be mediated by the schedule requirement. 相似文献

Humor use in romantic relationships: the effects of relationship satisfaction and pleasant versus conflict situations 总被引:1,自引:0,他引:1
In this study, the authors explored the use of positive, negative, and avoiding humor in 2 types of situations by individuals in romantic relationships. Participants (N = 154) rated their frequency of humor use in either a typical conflict scenario with their partner or a typical pleasant event. Participants also indicated their overall degree of romantic relationship satisfaction. Hierarchical regression analyses revealed that individuals who were more satisfied with their relationship reported higher levels of positive humor use and lower levels of negative and avoiding humor use. Furthermore, lower levels of negative and avoiding humor use were reported for the conflict situation. Last, a significant 2-way interaction revealed that individuals who were high in relationship satisfaction reported significantly lower levels of negative humor use in a conflict situation as compared with a pleasant encounter. In contrast, individuals who were low in relationship satisfaction reported the same high levels of negative humor use regardless of whether they were in a conflict situation or a pleasant encounter. The authors discuss these findings in terms of the need for further research to clearly delineate the factors that may influence the complex use of humor in romantic relationships. 相似文献
