Predictors of Psychosocial and Cognitive Adaptation in Children with Sickle Cell Syndromes

Examined the role of socioecological factors (family functioning and socioeconomic variables) in predicting behavioral and cognitive adaptation in children with sickle cell syndromes (SCD). Participants included 74 African American children and adolescents with SCD and their primary caretakers. Outcomes included internalizing and externalizing behavior symptoms, as rated by caretakers, as well as intellectual abilities and academic achievement, as assessed by individually administered standardized instruments. Family functioning consisted of both caretaker adjustment and family environment (i.e., family adaptability and cohesion). Hierarchical multiple regression analyses revealed that caretaker psychological adjustment predicted externalizing behaviors, while family environment (i.e., adaptability and cohesion) predicted neither behavioral nor cognitive functioning. Socioeconomic variables alone predicted intellectual abilities and academic achievement and also contributed to the prediction of child behavioral adaptation. Results are discussed in terms of relevant sociocultural issues and implications for family-level prevention and intervention.     

The impact of task complexity on information use in multi-attribute decision making

This study presents a process analysis of multi-attribute decision making. The decision problems concerned the selection of the most suitable candidate for a job opening. The problems varied in terms of complexity, i.e. the number of candidates and the number of attributes used to describe these alternatives. Results show that with an increasing number of alternatives, subjects (N = 48) used fewer attributes for the evaluation of alternatives, and made, on average, less references to the alternatives. The type of judgment most often used was absolute dimensional (comparison of an attribute to an absolute standard) and was used more often at the beginning than toward the end of the decision process. Overall, judgments were predominantly positive. The percentage of positive judgments decreased with increasing complexity, and toward the end of the decision process. Significantly more judgments, particularly positive ones, concerned the finally chosen alternative as compared to the rest of the alternatives. Finally, analysis of subjects' usage of decision rules revealed that increasing the number of alternatives resulted in an increasing use of elimination strategies. Implications of these findings for the design of decision aids will be discussed.     

Acceptance and commitment therapy (ACT) for people with dementia experiencing psychological distress: A hermeneutic single-case efficacy design (HSCED) series

Introduction

People with dementia have a high prevalence of psychological distress but are underserved with evidence-based psychological interventions. To promote choice and improve clinical outcomes, there is a necessity to test different psychological intervention options for this population.

Purpose

This study aimed to investigate the effectiveness and acceptability of acceptance and commitment therapy (ACT) for people with dementia, considering carer-supported, remote delivery and necessary therapy adaptations.

Methods

A hermeneutic single-case efficacy design series was used to analyse the therapy process and change for three clients with dementia and psychological distress. A matrix of quantitative and qualitative data was collated (“rich case records”) and subject to critical analyses by three independent psychotherapy experts (“judges”) who identified change processes and determined the outcome for each client.

Results

Adjudication concluded that one client made positive changes, specifically reliable reductions in psychological distress, which were largely attributable to ACT. Two clients remained unchanged.

Discussion/Conclusion

Where change was achieved, the ACT-specific processes of values, committed action and acceptance, in combination with non-specific therapy factors, including a strong client–carer relationship, existing client interests and individualised therapy adaptations, were facilitative. Hence, ACT may be a feasible and effective vehicle for therapeutic change by helping carers to better meet the needs of their loved ones. Future research to optimise ACT delivery in this population may be beneficial. Furthermore, the assessment of carer factors (e.g., their psychological flexibility and the client–carer relationship) may strengthen the evidence base for systemic ACT use.     

Female Paralympic Athlete Views of Effective and Ineffective Coaching Practices

People with physical disabilities are at a higher risk of developing secondary physical and mental health conditions, such as fatigue, obesity, and depression. The purpose of this study was to explore female Paralympic athlete views of effective and ineffective coaching practices. Individual semistructured interviews were conducted with 8 athletes who achieved an average of 8 combined Paralympic and Parapan American medals. A hierarchical content analysis revealed the athletes’ perceptions and experiences of both effective and ineffective coaching strategies and behaviors, including how these experiences affected them on a personal and professional level. All athletes achieved tremendous athletic accomplishments and recognized the importance and value of their coaches in helping them reach such high standards of success. In addition, the participants spoke about male coaches inappropriately addressing their disability and gender and how it negatively influenced their psychological well-being. These results are particularly troublesome when you consider that females with a disability are more susceptible to experiencing discrimination, exclusion, or harassment and more likely to experience body image issues compared to their male counterparts. This research adds to the small body of coaching knowledge in parasport and is one of the first studies to include an all-female sample of Paralympic athletes. In addition, it offers a number of practical implications for coaches, athletes, and the Paralympic community.

Lay Summary: This study adds to the small body of coaching knowledge in parasport by interviewing female Paralympic athletes. Athletes talked about coaches who enhanced their athletic performance and personal development, whereas others spoke about male coaches inappropriately addressing their disability and gender and how it negatively influenced their psychological well-being.     

The importance of multiple exemplar instruction in the establishment of novel verbal behavior

According to traditional linguistic accounts language, and its generative nature, cannot be taught. From a behavior analytic perspective, language is like any other behavior; it is learned and amenable to change. Based upon Skinner's radical behavioral analysis of verbal behavior, specific procedures have been designed to promote novel verbal relations. However, despite the strength and utility of this approach, using behavioral principles to understand the generativity of language has been challenging. Dependent upon the specific theory (e.g., stimulus equivalence, relational frame theory, bidirectional naming) within the radical behavioral orientation, researchers arrange unique procedures to evaluate the variables responsible for this phenomenon. This paper presents the commonalities and differences of two procedures (i.e., multiple exemplar training, multiple exemplar instruction) with examples of research highlighting the use of both in producing generativity. Further, it describes how multiple exemplar instruction is independent from other procedures leading to this outcome, and concludes by providing recommendations for both research and practice.     

Accounting for sequential trial effects in the flanker task: Conflict adaptation or associative priming?

The conflict-control loop theory proposes that the detection of conflict in information processing triggers an increase in cognitive control, resulting in improved performance on the subsequent trial. This theory seems consistent with the robust finding that conflict susceptibility is reduced following correct trials associated with high conflict: the conflict adaptation effect. However, despite providing favorable conditions for eliciting and detecting conflict-triggered performance adjustments, none of the five experiments reported here provide unequivocal evidence of such adjustments. Instead, the results corroborate and extend earlier findings by demonstrating that the conflict adaptation effect, at least in the flanker task, is only present for a specific subset of trial sequences that is characterized by a response repetition. This pattern of results provides strong evidence that the conflict adaptation effect reflects associative stimulus-response priming instead of conflict-driven adaptations in cognitive control.     

Source monitoring in a generative task

Following exposure to experimenter-provided examples of space creatures, people tend to conform to the features contained in the examples when creating their own novel space creatures. In three experiments, we manipulated factors known to affect source-monitoring accuracy to determine how these manipulations would influence conformity to experimenter-provided examples. In Experiment 1 we altered people's cognitive agenda by means of the instructions given before the drawing task. In Experiment 2 we examined how time pressure would affect the level of conformity, and in Experiment 3 we manipulated the availability of the creatures during the drawing task by making them available to half the participants. Conformity decreased when extended source-monitoring processes were engaged and increased when these processes were disrupted. The results from the three experiments were consistent with the principles of the source-monitoring framework.     

Interleaving reading and acting while following procedural instructions

Memory for an interactive procedure acquired from written instructions is improved if the procedure can be carried out while the instructions are being read. The size of the read-act cycle was manipulated in Experiments 1 and 2 by comparing chunked instruction-following, in which 3 or 4 steps are read then performed with single-step conditions. In both experiments, enforced chunking improved subsequent unaided performance of the procedure. In Experiment 3, participants were allowed to manage the interleaving of reading and acting. The imposition of a small behavioral cost (a single mouse point-and-click operation) on the switch between instructions and device encouraged more chunking and better subsequent test performance. The authors concluded that the interleaving of reading and acting is an important practical concern in the design of interactive procedures and that more effective chunk-based strategies can quite readily be encouraged.     

Transformational Leadership and Sports Performance: The Mediating Role of Intrinsic Motivation1

We developed and tested a model in which transformational leadership affects sports performance indirectly, through the mediating effects of intrinsic motivation. During the season, 168 university athletes provided data on their perceptions of their coach's transformational leadership and their own intrinsic motivation. At the end of the season, their coaches assessed the performance of the athletes. Using LISREL VIII, three models were estimated following the sequence of mediator tests outlined by Kelloway (1996, 1998). The proposed model received considerable support. The results isolate intrinsic motivation as a mediator of the relationship between transformational leadership and sports performance, suggesting that transformational leadership may enhance intrinsic interest in the task.
