Competition Enhances Risky Decision-Making Performance via Prefrontal Synchrony in Women

Clinical assessment of decision-making often focuses on individual cognitive deficits, yet most high-stakes choices occur within complex social frameworks. Risky decision-making is a multi-dimensional construct influenced by various neurophysiological factors, including mental workload and reward processing [1, 2]. In psychiatric conditions such as obsessive-compulsive disorder or behavioral addictions, these processes are frequently disrupted, leading to maladaptive choices and impaired social functioning [3, 4, 5]. While functional near-infrared spectroscopy (a non-invasive imaging method that measures brain activity by detecting changes in blood oxygenation) has emerged as a tool for monitoring cortical activation, the specific neural signatures that distinguish different social strategies remain poorly defined [6, 7, 8]. A new study now offers insights into the neural and computational mechanisms that drive dyadic choice (decisions made by pairs of individuals) in competitive and cooperative environments [9].
