Sounds emitted by different sources arrive at our ears as a mixture that must be disentangled before meaningful information can be retrieved. It is still a matter of debate whether this decomposition happens automatically or requires the listener’s attention. These opposite positions partly stem from different methodological approaches to the problem. We propose an integrative approach that combines the logic of previous measurements targeting either auditory stream segregation (interpreting a mixture as coming from two separate sources) or integration (interpreting a mixture as originating from only one source). By means of combined behavioral and event-related potential (ERP) measures, our paradigm has the potential to measure stream segregation and integration at the same time, providing the opportunity to obtain positive evidence of either one. This reduces the reliance on zero findings (i.e., the occurrence of stream integration in a given condition can be demonstrated directly, rather than indirectly based on the absence of empirical evidence for stream segregation, and vice versa). With this two-way approach, we systematically manipulate attention devoted to the auditory stimuli (by varying their task relevance) and to their underlying structure (by delivering perceptual tasks that require segregated or integrated percepts). ERP results based on the mismatch negativity (MMN) show no evidence for a modulation of stream integration by attention, while stream segregation results were less clear due to overlapping attention-related components in the MMN latency range. We suggest future studies combining the proposed two-way approach with some improvements in the ERP measurement of sequential stream segregation. 相似文献

The day–night paradigm, where children respond to a pair of pictures with opposite labels for a series of trials, is a widely used measure of interference control. Recent research has shown that a happy–sad variant of the day–night task was significantly more difficult than the standard day–night task. The present research examined whether the perceptual discriminability of the happy–sad task pictures impacts young children's interference control. When test card pairs were equally distinct between conditions, children performed similarly regardless of whether the happy–sad or day–night response terms were employed (Experiment 1). Two versions of the happy–sad task were administered in Experiment 2, and children experienced significantly more interference when the stimuli were perceptually similar than when they were distinct. Theoretical implications for the role attentional demands play in interference control in Stroop-like tasks for pre-readers are discussed. 相似文献

Understanding how parents influence their child’s medical procedures can inform future work to reduce pediatric procedural distress and improve recovery outcomes. Following a pediatric injury or illness diagnosis, the associated medical procedures can be potentially traumatic events that are often painful and distressing and can lead to the child experiencing long-term physical and psychological problems. Children under 6 years old are particularly at risk of illness or injury, yet their pain-related distress during medical procedures is often difficult to manage because of their young developmental level. Parents can also experience ongoing psychological distress following a child’s injury or illness diagnosis. The parent and parenting behavior is one of many risk factors for increased pediatric procedural distress. The impact of parents on pediatric procedural distress is an important yet not well-understood phenomenon. There is some evidence to indicate parents influence their child through their own psychological distress and through parenting behavior. This paper has three purposes: (1) review current empirical research on parent-related risk factors for distressing pediatric medical procedures, and longer-term recovery outcomes; (2) consider and develop existing theories to present a new model for understanding the parent–child distress relationship during medical procedures; and (3) review and make recommendations regarding current assessment tools and developing parenting behavior interventions for reducing pediatric procedural distress. 相似文献

Functional communication training and noncontingent reinforcement in treatment of stereotypy 下载免费PDF全文

A 6‐year‐old boy with autism spectrum disorder engaged in automatically maintained stereotypy in the form of opening and closing doors. A functional analysis confirmed that he also emitted problem behavior that was maintained by access to stereotypy. We evaluated the separate and combined effects of functional communication training and arbitrary noncontingent reinforcement on both response classes. Results showed that the combination of functional communication training and noncontingent reinforcement was more effective at reducing stereotypy than either intervention on its own, although effects on problem behavior were unclear. These results suggest that combinations of interventions may be useful in the treatment of automatically maintained problem behavior. 相似文献

The social-cognitive processing model suggests that a socially constrained environment may impede adjustment to a chronic illness. The present study primarily investigated the mediating psychological pathways through which social constraints on cancer-related disclosure, low optimism, disengagement-oriented coping, and brooding could be associated with low levels of psychosocial adjustment. One hundred twenty-five female breast cancer survivors participated in a cross-sectional study. Path analysis was used to examine the proposed model. Low optimism, increased social constraints, and higher levels of brooding appeared to be risk factors for poor psychosocial adjustment to breast cancer. Disengagement-oriented coping and brooding partially mediated the relationship between social constraints and adjustment. Brooding totally mediated the relationship between disengagement-oriented coping and adjustment. The current findings provide support for the value of the social-cognitive processing model among breast cancer survivors. The mapping of psychological pathways of adjustment to breast cancer may have useful clinical implications for better adjustment outcomes. 相似文献

Media-multitasking involves simultaneous engagement with information streams from multiple media sources, and is most prevalent in young adults. Heavy media-multitasking has been associated with differential performance on tasks involving attentional control and working memory relative to light media-multitasking. The aim of the present study was to systematically investigate relationships between executive functions and self-reported media-multitasking. Healthy participants (N?=?112, aged 18–25, male N?=?36) completed a battery of 10 traditional executive function tasks, that included assessments of attentional inhibition, response inhibition, working memory, and cognitive flexibility. Scores on the individual executive function tasks were correlated against frequency of self-reported media-multitasking, but no significant relationships were found. Trait anxiety, however, was found to be significantly associated with greater frequency of self-reported media-multitasking. The present study found no evidence of a relationship between the frequency of self-reported media-multitasking and executive functioning. The possible reasons for this are discussed. 相似文献

Letting Go: Conceptualizing Intervention De‐implementation in Public Health and Social Service Settings 下载免费PDF全文

The discontinuation of interventions that should be stopped, or de‐implementation, has emerged as a novel line of inquiry within dissemination and implementation science. As this area grows in human services research, like public health and social work, theory is needed to help guide scientific endeavors. Given the infancy of de‐implementation, this conceptual narrative provides a definition and criteria for determining if an intervention should be de‐implemented. We identify three criteria for identifying interventions appropriate for de‐implementation: (a) interventions that are not effective or harmful, (b) interventions that are not the most effective or efficient to provide, and (c) interventions that are no longer necessary. Detailed, well‐documented examples illustrate each of the criteria. We describe de‐implementation frameworks, but also demonstrate how other existing implementation frameworks might be applied to de‐implementation research as a supplement. Finally, we conclude with a discussion of de‐implementation in the context of other stages of implementation, like sustainability and adoption; next steps for de‐implementation research, especially identifying interventions appropriate for de‐implementation in a systematic manner; and highlight special ethical considerations to advance the field of de‐implementation research. 相似文献

The goal of the present study was to examine the links between life events and adolescents' social behaviors (prosocial and aggressive behaviors) toward specific targets and to examine how empathic concern may play a role in these associations. The study examined two hypotheses: both the mediating role of empathic concern and the moderating role of empathic concern. The sample included 311 high school students from the Midwest (M age = 16.10 years; age range = 14–19 years; 58.7% girls; 82.7% White, 13.6% Latino). The results demonstrated support for the moderation model as well as complex links between life events and prosocial and aggressive behaviors toward specific targets. The discussion focuses on the role of empathic concern in understanding how life events are ultimately associated with adolescents' social development. 相似文献
