The abilities of children diagnosed with developmental dyscalculia (DD) were examined in two types of object enumeration: subitizing, and small estimation (5–9 dots). Subitizing is usually defined as a fast and accurate assessment of a number of small dots (range 1 to 4 dots), and estimation is an imprecise process to assess a large number of items (range 5 dots or more). Based on reaction time (RT) and accuracy analysis, our results indicated a deficit in the subitizing and small estimation range among DD participants in relation to controls. There are indications that subitizing is based on pattern recognition, thus presenting dots in a canonical shape in the estimation range should result in a subitizing‐like pattern. In line with this theory, our control group presented a subitizing‐like pattern in the small estimation range for canonically arranged dots, whereas the DD participants presented a deficit in the estimation of canonically arranged dots. The present finding indicates that pattern recognition difficulties may play a significant role in both subitizing and subitizing deficits among those with DD. 相似文献

This article examines the responsibilities of researchers who conduct exploratory research to provide a service to vulnerable respondents. The term “service” is used to denote the provision of a tangible benefit in relation to the research question that is apart from the altruistic research benefits. This article explores what this “service” could look like, who might be responsible for providing it, and the challenges associated with such a service. The article argues that not providing a tangible benefit to vulnerable research participants is inconsistent with the principle of social justice that undergirds much of the rationale for conducting health disparities research. 相似文献

The potential impact on psychological well-being of working in the caring professions in the aftermath of trauma and disaster has been recognized for many years, with terms such as burnout, compassion fatigue, and vicarious traumatization coined to describe stress-related conditions. Although prevalent, these conditions do not affect all workers in the field. Various studies have investigated potential risk and protective factors. It is argued that the outcomes of this research should be used to guide practical interventions in the workplace designed to minimize stress-related problems. A framework that incorporates interventions at the primary, secondary, and tertiary prevention levels is outlined, and research investigating the efficacy of interventions at each of these levels is recommended. 相似文献

We investigated the influence of motivating operations on the generalization of newly taught mands across settings and communication partners for 3 children with autism. Two conditions were implemented prior to generalization probes. In the first condition, participants were given access to a preferred item until they rejected the item (i.e., abolishing operation). In the second condition, the item was not available to participants prior to generalization probes (i.e., establishing operation). The effects of these conditions on the generalization of newly taught mands were evaluated in a multielement design. Results indicated differentiated responding during generalization probes in which more manding with the target mand was observed following the presession no‐access condition than in the presession access condition. These results support the consideration of motivating operations when assessing generalization of target mands to various untrained contexts. 相似文献

This paper provides an overview and task analysis for creating a continuous ABC data‐collection application using Xcode on a Mac computer. Behavior analysts can program an ABC data collection system, complete with a customized list of target clients, antecedents, behaviors, and consequences to be recorded, and have the data automatically sent to an e‐mail account after observations have concluded. Further suggestions are provided to customize the ABC data‐ collection system for individual preferences and clinical needs. 相似文献

To control order effects in questionnaires containing paired comparisons, Ross (1934) described an optimal ordering of the pairings. The pairs can also be balanced so that every stimulus appears equal numbers of times as the first and the second member of a pair. First, we describe and illustrate the optimally spaced, balanced ordering of pairings. Then we show how the optimally spaced, balanced order can be used to implement a matrix-sampling design or a fully incomplete design when the number of stimuli n is so large that respondents cannot reasonably be expected to judge all n(n - 1)/2 pairs. The algorithm for balancing and optimally spacing the list of pairs is described. 相似文献

Aims: This study examines the relationship between expert supervisors' professional experiences and their views about the importance of different psychotherapy techniques. Method: Thirty psychodynamic‐interpersonal (PI) supervisors and 13 cognitive‐behavioural (CB) supervisors (N=43) were instructed to rate 20 therapeutic techniques according to how characteristic each technique is of an ideally‐conducted session within their theoretical orientation. The measure used for this assessment was the Comparative Psychotherapy Process Scale. Results: Findings demonstrated that supervisors' beliefs about ideal therapeutic techniques are related to their number of years in post‐graduate clinical practice, training, and supervising trainees, as well as to the number of publications they have authored. Further, experience within a given orientation tends to lead to a greater endorsement of techniques within that orientation, although this finding is more uniform for CB supervisors than PI supervisors. Finally, differential types of experience lead to differential focusing on specific techniques. Discussion: The clinical importance of these findings is explored. 相似文献

Rationale: To date relatively little research has examined the effectiveness of psycho‐educational courses provided in a primary care setting to adults with mild‐to‐moderate mental health concerns. Aims: To determine whether group psycho‐education could be a viable alternative to individual counselling by (1) assessing the clinical effectiveness of an 8‐week psycho‐educational course, and (2) examining the group outcomes in comparison with individual treatment outcomes from a previous study in the same counselling service. Method: A total of 57 participants attending a psycho‐educational course provided data over a 36‐month period, using the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE‐OM) pre‐ and post‐intervention. A comparison was then made with the data of 58 previous participants of individual counselling evaluation, using the same CORE‐OM system. Results: Participants reported significantly lower levels of psychological distress after attending the course and these results are comparable to outcomes measured in the same service for individual counselling, indicating that group interventions could be considered a legitimate alternative to individual counselling, thus increasing cost effectiveness and reducing waiting times. Limitations of the study and implications for practice and further investigation are considered. 相似文献

This paper provides a brief overview of recent developmental research on themes related to children's social identities. Initially, consideration is given to the capacity for social categorization, following which attention is given to children's developing conceptions of social identities, their identification with social groups, and the consequences of identification upon various phenomena such as ingroup favouritism and well‐being. Finally, some personal thoughts on the wider political implications of this research are offered. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The current study evaluated the effect of participating in simulated gambling activities on happiness levels of 3 nursing home residents. A 4‐component analysis was used to measure objective responses associated with happiness during baseline, varying durations of engagement in simulated gambling activities, and 2 follow‐up periods. Results indicated that all residents exhibited a higher percentage of happiness levels while engaged in simulated gambling activities compared with baseline. Follow‐up assessment took place 10 min and 30 min following the intervention; no lasting effects were observed. 相似文献
