Delay discounting describes the process wherein rewards lose value as a function of their delayed receipt; how quickly rewards lose value is termed the rate of delay discounting. Rates of delay discounting are robust predictors of much behavior of societal importance. One efficient approach to obtaining a human subject’s rate of delay discounting is via the 21- and 27-item Monetary Choice Questionnaires, brief dichotomous choice tasks that assess preference between small immediate and larger delayed monetary outcomes. Unfortunately, the scoring procedures for the Monetary Choice Questionnaires are rather complex, which may serve as a barrier to their use. This report …


Human Choices Between Variable And Fixed Rewards In Hypothetical Variable-Delay And Double-Reward Discounting Procedures, Todd Mckerchar, James E. Mazur Jun 2016

Prior research has shown that nonhumans show an extreme preference for variable- over fixed-delays to reinforcement. This well-established preference for variability occurs because a reinforcer’s strength or “value” decreases according to a curvilinear function as its delay increases. The purpose of the present experiments was to investigate whether this preference for variability occurs with human participants making hypothetical choices. In three experiments, participants recruited from Amazon Mechanical Turk made choices between variable and fixed monetary rewards. In a variable-delay procedure, participants repeatedly chose between a reward delivered either immediately or after a delay (with equal probability) and a reward after …

The objective was to test an intervention to reduce failed rates for psychiatric appointments. We collected data for this study of the characteristics of patients who missed appointments from March 2011 through September 2012. A phone triage assessment intervention was implemented to address chronic first-time failed attendance appointments (N = 78). The main reason for failed appointments was transportation difficulties. The first-time appointment show rate increased after implementing an assessment intervention. Phone assessment intervention was practical and may improve nonattendance for psychiatric appointments. The discussion reflects speculations about causes and possible measures to make services more accessible.
