Risky behavior in virtual reality: The roles of personality, environment, and physiology.
PLoS One
January 2025
Faculty of Philosophy, Department of Psychology, University of Novi Sad, Novi Sad, Serbia.
Virtual reality (VR) provides a unique opportunity to simulate various environments, enabling the observation of human behavior in a manner that closely resembles real-world scenarios. This study aimed to explore the effects of anticipating reward or punishment, personality traits, and physiological arousal on risky decision-making within a VR context. A custom VR game was developed to simulate real-life experiences.

Traditional post-stroke rehabilitation strategies often show limited generalization beyond trained materials, underscoring the need for novel interventions targeting the underlying neural mechanisms.
Method: This study investigates the feasibility and potential effectiveness of real-time functional magnetic resonance imaging (fMRI) neurofeedback (NFB) intervention for reading deficits associated with stroke and aphasia.
Male rats choose higher doses of nicotine in anticipation of a signalled period of drug non-availability.

School of Psychology, University of New South Wales, Australia. Electronic address:
Humans and animals use information about future access to rewards to influence their behaviour in the present, however the evidence for this is largely anecdotal. Here we use the nicotine intravenous self-administration paradigm to ask whether rats can use an auditory stimulus signalling a long (450 s) signalled time-out on the next trial to influence their nicotine intake in the present. Rats were trained to choose between low (15 µg/kg/infusion), medium (30 µg/kg/infusion) or high (60 µg/kg/infusion) doses of nicotine on any given trial.

Pupil size is a well-established marker of cognitive effort, with greater efforts leading to larger pupils. This is particularly true for pupil size during task performance, whereas findings on anticipatory effort triggered by a cue stimulus are less consistent. For example, a recent report by Frömer et al.

Background/objectives: Learning is classically modeled to consist of an acquisition period followed by a mastery period when the skill no longer requires conscious control and becomes automatic. Dopamine neurons projecting to the ventral striatum (VS) produce a teaching signal that shifts from responding to rewarding or aversive events to anticipating cues, thus facilitating learning. However, the role of the dopamine-receptive neurons in the ventral striatum, particularly in encoding decision-making processes, remains less understood.
