Summary of "An Examination of Group Size and Valence in Delay Discounting of Shared Outcomes."

Previous research has examined delay discounting in a group context, where the outcomes are shared with others. These studies indicate shallow delay discounting in a group context compared to an individual context. The present set of studies aimed to explore the impact of two factors, group size (the number of others in the group) and group valence (liked or disliked others in the group), that may affect delay discounting in a group context. Results of the two studies replicated previous results, where shallow delay discounting was observed in the group context compared to the individual context. Within the group context of both studies, delay discounting was not impacted by whether the group was composed of liked or disliked others. While Study 1 indicated no effect of group size, Study 2 indicated shallow delay discounting for a larger group compared to a smaller group. These results contribute the nascent literature on delay discounting in group contexts.

An investigation of delay and probability discounting in hoarding disorder.

Behavioral impulsivity may be a mechanism of hoarding disorder (HD). A commonly used and well-validated measure of impulsivity is the delay and probability discounting task, which consists of making d...

Waiting and working for rewards: Attention-Deficit/Hyperactivity Disorder is associated with steeper delay discounting linked to amygdala activation, but not with steeper effort discounting.

Children and adolescents with ADHD have a relatively strong preference for smaller immediate rewards over larger delayed rewards (steep delay discounting). It is unknown whether such steep discounting...

Influence of Second Outcome on Monetary Discounting.

The rates that an outcome (e.g., money) loses value as delay increases or probability decreases are called delay and probability discounting, respectively. Discounting is typically studied by asking p...

Further Comparison of 5-Trial Adjusting Delay and Probability Loss Tasks Over a Wide Range of Amounts.

Researchers have recently developed brief methods to measure discounting. One brief method uses 5-trial adjusting-delay or -probability tasks. These tasks have provided similar rates of discounting to...

Cigarette smokers show greater delay discounting (devaluation of delayed consequences) than non-smokers, suggesting that rapid devaluation of the future contributes to tobacco use through a mechanism ...

Medical and Biotech [MESH] Definitions

The tendency to devalue an outcome as a function of its temporal delay or probability of achievement. It can be evaluated in a psychological paradigm that involves the choice between receiving a smaller immediate reward or a larger delayed reward, and may be used to provide a measure of impulsive behavior.

An organization of insurers or reinsurers through which particular types of risk are shared or pooled. The risk of high loss by a particular insurance company is transferred to the group as a whole (the insurance pool) with premiums, losses, and expenses shared in agreed amounts.

The informal or formal organization of a group of people based on a network of personal relationships which is influenced by the size and composition, etc., of the group.

The inspection of one's own body, usually for signs of disease (e.g., BREAST SELF-EXAMINATION, testicular self-examination).

Beliefs and values shared by all members of the organization. These shared values are reflected in the day to day operations of the organization.
