Neural correlates of wishful thinking

Area of Science:

• Cognitive Neuroscience
• Social Psychology

Background:

• Wishful thinking (WT) involves overestimating desirable event likelihoods.
• WT can be influenced by personal interest and social connections.
• The cognitive underpinnings of WT, whether attention-based or higher-level, remain debated.

Purpose of the Study:

• To investigate the neural mechanisms of wishful thinking.
• To differentiate between attention-based and higher-level cognitive processes in WT.
• To explore the role of the reward system in WT.

Main Methods:

• Functional magnetic resonance imaging (fMRI) study.
• Participants predicted football game outcomes for favorite vs. least favorite teams.
• Analysis of brain activity and functional connectivity patterns.

Main Results:

• Brain activity in the occipital and fusiform gyri differentiated favorite from least favorite team trials.
• Functional connectivity between this visual area and the reward system correlated with WT.
• Prefrontal cortex activity distinguished teams but did not correlate with WT magnitude.

Conclusions:

• Wishful thinking appears to be driven by an attention bias linked to the human reward system.
• Prefrontal cortex activity may relate to social identification rather than the degree of WT.
• Findings support an attentional bias model for wishful thinking.
