Description
Previous studies in risk-sensitive foraging have commonly observed changes in choice when delay and amount are manipulated. Similarly, numerous studies have observed changes in foraging when predatory alarm cues are present. Although, no studies have determined if or how predatory alarm cues might influence risk-sensitive foraging. Using a within subjects design, rats (rattus norvegicus, n = 10) were exposed to a water (Control Condition) followed by a predatory alarm cue (Alarm Condition) while choosing between a fixed and variable option. Our data illustrated a significant increase in risk-proneness across the Control to Alarm Condition.
