A mechanism for reducing delay discounting by altering temporal attention

Rewards that are not immediately available are discounted compared to rewards that are immediately available. The more a person discounts a delayed reward, the more likely that person is to have a range of behavioral problems, including clinical disorders. This latter observation has motivated the search for interventions that reduce discounting. One surprisingly simple method to reduce discounting is an "explicit-zero" reframing that states default or null outcomes. Reframing a classical discounting choice as "something now but nothing later" versus "nothing now but more later" decreases discount rates. However, it is not clear how this "explicit-zero" framing intervention works. The present studies delineate and test two possible mechanisms to explain the phenomenon. One mechanism proposes that the explicit-zero framing creates the impression of an improving sequence, thereby enhancing the present value of the delayed reward. A second possible mechanism posits an increase in attention allocation to temporally distant reward representations. In four experiments, we distinguish between these two hypothesized mechanisms and conclude that the temporal attention hypothesis is superior for explaining our results. We propose a model of temporal attention whereby framing affects intertemporal preferences by modifying present bias.     

Cortical control of sinus arrhythmia in man studied by spectral analysis

Eighteen healthy male volunteers, 21–26 years old, participated in a study intended to detect cortical control of beat-to-beat heart rate variability independent of the effects on breathing and mean heart rate. They were tested while seated and standing relaxed (baseline), and while performing tasks requiring concentrated attention while sitting. The mental concentration elicited a typical cardiorespiratory response manifested by moderate acceleration and shallowing of respiration with a small increase of mean heart rate (HR), a pattern already widely acknowledged as typically associated with concentration. With the aid of a variable tone delivered to the ear as a guide, the subjects were trained to breathe at the same rate without concentrating in order to test the influence of respiration on the concentration pattern. ECG, thermistor pneumogram and ear-lobe photo-plethysmogram were recorded and data reduction was performed on 3 minute or 1 minute data sequences selected for the best steady-state. Statistical treatment was limited to a subgroup of 10 subjects in whom there was no overlapping of the spectra of respiratory and Traube-Hering-Mayer sinus arrhythmia (RSA and THM-SA, respectively). Mental concentration elicited significant depression of both RSA and THM-SA even if the respiratory parameters were kept constant.     

Teacher-Coaches’ Perceptions of Life Skills Transfer from High School Sport to the Classroom

Positive youth development is one of the primary goals of high school sport participation, yet the process of how youth transfer life skills from sport to other life domains is in need of greater examination. To offer a unique perspective, the purpose of the study explored teacher-coaches’ perceptions of the process of life skills transfer for student-athletes from high school sport to the classroom. Using a constructivist approach, 12 teacher-coaches (9 male, 3 female) with an average of 13?years (SD?=?5.7) experience as a teacher-coach completed in-person, semistructured interviews. Using model for life skills transfer as a guiding framework, the theoretical thematic analysis revealed specific student-athlete characteristics (e.g., internal assets, external assets), high school sport factors (e.g., inherent demands, coaching characteristics), and high school classroom factors (e.g., classroom contextual factors, student-athlete psychological processes) that helped or hindered the process of life skills transfer. The critical influences of individual awareness and agency and of congruence between contexts highlighted the value of understanding life skills transfer through a developmental systems lens. Results are discussed with specific recommendations for researchers and practitioners related to understanding life skills transfer.

Lay Summary: Positive youth development is a primary goal of high school sport participation, yet researchers can do more to understand the developmental outcomes from high school sport. In this study, teacher-coaches identified specific factors that can help and hinder student-athletes’ ability and likelihood of transferring life skills from high school sport to the classroom.     

Irrational Beliefs and Self-Management as Separable Predictors of Anxiety and Depression

Irrational beliefs and self-management are both cognitive-behavioral constructs that are integral in modern Rational-Emotive Behavior Therapy and Self-Management Therapy, respectively. Both irrational beliefs and self-management have been linked to anxiety and depression, and there is evidence for their usefulness for these types of distress. This is the first study to consider irrational beliefs and self-management as simultaneous predictors of anxiety and depression. An outpatient clinical sample (n = 51) completed measures of irrational beliefs, self-management, and emotional symptoms. Results indicated that as simultaneous predictors of fear and worry, self-management did not account for any additional variance accounted for by irrational beliefs. However, both irrational beliefs and self-management predicted unique variance in depression, negative affect, and positive affect. Exploratory analyses with single diagnosis (n = 26) and multiple diagnoses (n = 25) subsamples provided some divergent results. These results are discussed in terms of case conceptualization and potential future applications in the treatment of affective disorders, in particular depression.     

Tailoring Gratitude Interventions. How and for Whom Do They Work? The Potential Mediating Role of Reward Processing and the Moderating Role of Childhood Adversity and Trait Gratitude

Outcomes of gratitude interventions are encouraging, but inconsistent across studies. In addition, both mechanisms of change and effect modifiers for these interventions are largely unknown. Recent data point toward potential candidates and suggest reward processing may be a promising mechanism underlying these interventions, while childhood adversity (CA) and trait gratitude may impact on them. However, existing research aimed at investigating these hypotheses is scarce. Building on these, we examined the effectiveness of a gratitude intervention for decreasing depressive symptoms and negative affect and increasing positive affect. We also investigated changes in reward processing following intervention and explored differences in adherence and drop-out between groups. Finally, we investigated the moderating role of CA and trait gratitude.

Participants (N=237, ages between 18–56) were randomly allocated to a gratitude or active control condition (14 days). Following intervention, findings indicated a significant decrease in depressive symptoms and negative affect in both conditions. While positive affect remained stable, a significant time effect emerged for reward processing. CA severity, but not multiplicity, moderated the effectiveness of the intervention, adherence and drop-out. Trait gratitude moderated the effectiveness of the gratitude intervention only on depressive symptoms.

Gratitude interventions may not be the best fit for everyone. Thus, we recommend tailoring interventions, especially in individuals reporting a history of severe CA.
