Neurobiological influences on event perception: the role of catecholamines.

ABSTRACT:

Background

Event segmentation, the cognitive process of parsing continuous experiences into discrete events, plays a fundamental role in how humans perceive and interact with their environment. Guided by Event Segmentation Theory, this study investigates the modulation of event segmentation by the catecholaminergic system by methylphenidate (MPH).

Methods

Healthy adult participants (N = 52) engaged in a double-blind, counter-balanced, placebo-controlled experiment in which they watched a movie and identified event boundaries under placebo and MPH conditions.

Results

With the same information given, MPH increased the likelihood that the information was considered meaningful. Crucially, the number of situational changes and participant's prior experience had an interact
