Need for cognition moderates the relief of avoiding cognitive effort

Area of Science:

• Cognitive Psychology
• Neuroscience
• Decision Science

Background:

• Humans generally aim to maximize rewards and minimize costs in decision-making.
• Mental and physical effort are considered costs, leading to avoidance of demanding tasks.
• A predicted
• relief effect
• — positive affect from avoiding effort— lacks robust empirical support.

Purpose of the Study:

• To investigate whether avoiding high-effort tasks is inherently rewarding.
• To examine the influence of anticipated effort level on hedonic responses.
• To determine if individual differences, such as need for cognition, moderate the relief effect.

Main Methods:

• Two experiments involving a gambling task where non-reward outcomes triggered an effort task.
• Participants received cues indicating whether the upcoming effort task would be easy or hard.
• Hedonic responses were measured before and after effort task feedback.

Main Results:

• Lower hedonic responses were reported for no-reward outcomes when high effort was anticipated compared to low effort.
• Higher hedonic responses were reported for reward outcomes when high effort was anticipated and avoided.
• The relief effect was diminished in participants with a high need for cognition.

Conclusions:

• Avoiding high-effort tasks yields a rewarding experience, or relief.
• The magnitude of this relief effect is influenced by individual disposition towards cognitive engagement.
• Further research is needed to understand if disposition alters the perceived cost of effort or its role in cost-benefit analyses.
