On the Nature of Automatically Triggered Approach–Avoidance Behavior
Emotion Review, 2013Co-Authors: Regina Krieglmeyer, Jan De Houwer, Roland DeutschAbstract:Theory suggests that stimulus evaluations automatically evoke approach–Avoidance Behavior. However, the extent to which approach–Avoidance Behavior is triggered automatically is not yet clear. Furthermore, the nature of automatically triggered approach–Avoidance Behavior is controversial. We review research on two views on the type of approach–Avoidance Behavior that is triggered automatically (arm flexion/extension, distance change). Present evidence supports the distance-change view and corroborates the notion of an automatic pathway from evaluation to distance-change Behavior. We discuss underlying mechanisms (direct stimulus–response links, outcome anticipations, goals) as well as implications regarding the flexibility of the evaluation–Behavior link.

Evidence for the interchangeability of an Avoidance Behavior and a negative occasion setter.
Learning & behavior, 2008Co-Authors: Mieke Declercq, Jan De HouwerAbstract:Recent research on Avoidance Behavior provided evidence that such Behavior can function as a negative occasion setter. We tested this hypothesis further by investigating whether the modulatory function of a stimulus occasion setter transfers selectively to a relation previously modulated by an Avoidance Behavior, and whether the modulatory function of an Avoidance Behavior transfers selectively to a relation previously modulated by a stimulus occasion setter. The three experiments reported in this article provided evidence to support this hypothesis. Furthermore, the results of Experiment 1 suggested that the presence of counterconditioning trials is not a necessary condition for an Avoidance Behavior to function as a negative occasion setter. All three reported experiments support the occasion-setting account of Avoidance Behavior.

Avoidance Behavior can function as a negative occasion setter.
Journal of experimental psychology. Animal behavior processes, 2005Co-Authors: Jan De Houwer, Geert Crombez, Frank BaeyensAbstract:The authors put forward the hypothesis that Avoidance learning can result from the fact that participants learn (a) that a stimulus is followed by an unconditioned stimulus (US) when the Avoidance Behavior is not emitted and (b) that the stimulus is not followed by the US when the Avoidance Behavior is emitted. As such, Avoidance Behavior is assumed to function as a negative occasion setter. The results of a contingency judgment experiment involving 65 students showed that Avoidance Behavior indeed has the unique functional properties of a negative occasion setter (resistance to counterconditioning and selective transfer of modulation).

On the Control of Social Approach-Avoidance Behavior: Neural and Endocrine Mechanisms.
2017Co-Authors: Reinoud Kaldewaij, Saskia B. J. Koch, Inge Volman, Ivan Toni, Karin RoelofsAbstract:The ability to control our automatic action tendencies is crucial for adequate social interactions. Emotional events trigger automatic approach and Avoidance tendencies. Although these actions may be generally adaptive, the capacity to override these emotional reactions may be key to flexible Behavior during social interaction. The present chapter provides a review of the neuroendocrine mechanisms underlying this ability and their relation to social psychopathologies. Aberrant social Behavior, such as observed in social anxiety or psychopathy, is marked by abnormalities in approach-Avoidance tendencies and the ability to control them. Key neural regions involved in the regulation of approach-Avoidance Behavior are the amygdala, widely implicated in automatic emotional processing, and the anterior prefrontal cortex, which exerts control over the amygdala. Hormones, especially testosterone and cortisol, have been shown to affect approach-Avoidance Behavior and the associated neural mechanisms. The present chapter also discusses ways to directly influence social approach and Avoidance Behavior and will end with a research agenda to further advance this important research field. Control over approach-Avoidance tendencies may serve as an exemplar of emotional action regulation and might have a great value in understanding the underlying mechanisms of the development of affective disorders.

Effects of Predator Avoidance Behavior on the Coexistence of Competing Prey
The American naturalist, 2019Co-Authors: Pacifica Sommers, Peter ChessonAbstract:Predator Avoidance Behavior, in which prey limit foraging activities in the presence of predation threats, affects the dynamics of many ecological communities. Despite the growing theoretical appreciation of the role predation plays in coexistence, predator Avoidance Behavior has yet to be incorporated into the theory in a general way. We introduce adaptive Avoidance Behavior to a consumer-resource model with three trophic levels to ask whether the ability of prey-the middle trophic level-to avoid predators alters their ability to coexist. We determine the characteristics of cases in which predator Avoidance Behavior changes prey coexistence or the order of competitive dominance. The mechanism underlying such changes is the weakening of apparent competition relative to resource competition in determining niche overlap, even with resource intake costs. Avoidance Behavior thus generally promotes coexistence if prey partition resources but not predators, whereas it undermines coexistence if prey partition predators but not resources. For any given case, the changes in the average fitness difference between two species resulting from Avoidance Behavior interact with changes in niche overlap to determine coexistence. These results connect the substantial body of theoretical work on Avoidance Behavior and population dynamics with the body of theory on competitive coexistence.
