摘要
在混合觅食中,觅食者会在整个觅食过程中在多个斑块中寻找多个目标,这模拟了一系列真实世界的场景。这项研究考察了人类混合觅食中结果的不确定性、不同目标类型的普遍性以及目标的奖励价值。我们的实证研究结果表明,在混合觅食中,人们的行为始终倾向于规避风险。也就是说,人们表现出对确定性的偏好,并积极避免承担风险。虽然改变风险目标的普遍性或奖励价值确实会影响人们对风险的厌恶,但风险的总体影响仍然占主导地位。此外,模拟结果表明,观察到的规避风险策略是次优的,因为它阻碍了觅食者获得最大的总体收益。这些结果强调了结果的不确定性在形成混合觅食行为中的关键作用,并揭示了连接决策理论和混合觅食理论的潜在理论发展。(PsycInfo Database Record (c) 2024 APA, 版权所有)。
Risky hybrid foraging: The impact of risk, reward value, and prevalence on foraging behavior in hybrid visual search.
In hybrid foraging, foragers search for multiple targets in multiple patches throughout the foraging session, mimicking a range of real-world scenarios. This research examines outcome uncertainty, the prevalence of different target types, and the reward value of targets in human hybrid foraging. Our empirical findings show a consistent tendency toward risk-averse behavior in hybrid foraging. That is, people display a preference for certainty and actively avoid taking risks. While altering the prevalence or reward value of the risky targets does influence people's aversion to risk, the overall effect of risk remains dominant. Additionally, simulation results suggest that the observed risk-averse strategy is suboptimal in the sense that it prevents foragers from maximizing their overall returns. These results underscore the crucial role of outcome uncertainty in shaping hybrid foraging behavior and shed light on potential theoretical developments bridging theories in decision making and hybrid foraging.

期刊介绍:
The Journal of Experimental Psychology: General publishes articles describing empirical work that bridges the traditional interests of two or more communities of psychology. The work may touch on issues dealt with in JEP: Learning, Memory, and Cognition, JEP: Human Perception and Performance, JEP: Animal Behavior Processes, or JEP: Applied, but may also concern issues in other subdisciplines of psychology, including social processes, developmental processes, psychopathology, neuroscience, or computational modeling. Articles in JEP: General may be longer than the usual journal publication if necessary, but shorter articles that bridge subdisciplines will also be considered.
