Title:
The influence of episodic foresight on delay discounting and demand for alcohol
Authors:
Bulley, Adam & Gullo, Matthew J.
Journal:
Addictive Behaviors (2017), 66, 1-6

Highlights

  • Imagining the future, known as episodic foresight, may attenuate impulsivity.
  • Episodic foresight reduced delay discounting and alcohol demand intensity.
  • The effect of episodic foresight on impulsivity may extend to alcohol decisions.

Abstract

Background

There is a near-universal tendency to discount the value of delayed rewards relative to those available in the here and now. The rate at which future rewards become devalued over time, delay discounting, is an important individual difference variable related to impulsivity and is elevated in externalising disorders, including alcohol use disorders. Recent research suggests that vividly imagining personally relevant future events (episodic foresight) during an intertemporal choice task can attenuate the rate at which delayed rewards are discounted.

Objectives

The present study sought to extend these findings by examining the effect of episodic foresight on both delay discounting and alcohol-related decision-making.

Methods

Forty-eight college students were administered both modified intertemporal choice and hypothetical alcohol purchase tasks during which personally relevant episodic future event cues or control imagery cues were presented.

Results

Engaging in episodic foresight reduced both the rate at which delayed monetary rewards were discounted and initial alcohol demand intensity (but not other demand indices) relative to control imagery.

Conclusions

Findings suggest that the attenuating effect of episodic foresight on impulsivity may be limited to particular aspects of impulsive choice.
