“…through an increase in co-contraction levels and/or feedback gains [55], as an effect of arousal. While we are not aware of direct evidence regarding fear of pain, experiments using height to induce fear of movement [56,57] and experiments using images with negative valence [58,59] support the assumed mechanism.…”

“…Just how such effects arise from particular patterns of behavior (as when subjects are controlling their foraging disc), however, remains elusive, and will require more investigation. We saw some hint that foraging speed might be the culprit, since subjects tended to move their disc more slowly when the darts were pointing at them (perhaps due to a type of "freeze response" related to threatening stimuli; e.g., Stins & Beek, 2007). But this effect was clearly not as strong or reliable as the primary effect of foraging time.…”

The automaticity of perceiving animacy: Goal-directed motion in simple shapes influences visuomotor behavior even when task-irrelevant

Visual processing recovers not only simple features, such as color and shape, but also seemingly higherlevel properties, such as animacy. Indeed, even abstract geometric shapes are readily perceived as intentional agents when they move in certain ways, and such percepts can dramatically influence behavior. In the wolfpack effect, for example, subjects maneuver a disc around a display in order to avoid several randomly moving darts. When the darts point toward the disc, subjects (falsely) perceive that the darts are chasing them, and this impairs several types of visuomotor performance. Are such effects reflexive, automatic features of visual processing? Or might they instead arise only as contingent strategies in tasks in which subjects must interact with (and thus focus on the features of) such objects? We explored these questions in an especially direct way-by embedding such displays into the background of a completely independent "foraging" task. Subjects now moved their disc to collect small "food" dots (which appeared sequentially in random locations) as quickly as possible. The darts were task-irrelevant, and subjects were encouraged to ignore them. Nevertheless, foraging was impaired when the randomly moving darts pointed at the subjects' disc, as compared to control conditions in which they were either oriented orthogonally to the subjects' disc or pointed at another moving shape-thereby controlling for nonsocial factors. The perception of animacy thus influences downstream visuomotor behavior in an automatic manner, such that subjects cannot completely override the influences of seemingly animate shapes even while attempting to ignore them.

“…These were included in an elegant study by Azevedo et al (2005) who used a stabilometric platform to objectively assess body sway and observed freezing (reduced body sway and bradycardia) in response to mutilation but not neutral and sports pictures. Only very few other researchers have used a stabilometric platform to quantify postural freezing, but all have found associations between posture and either anxiety or threatening stimuli (Carpenter, Frank, Adkin, Paton, & Allum, 2004;Facchinetti, Imbiriba, Azevedo, Vargas, & Volchan, 2006;Lopes et al, 2009;Roelofs, Hagenaars, & Stins, 2010;Stins & Beek, 2007).…”

In the present study, we investigated the effect of prior aversive life events on freezing-like responses. Fifty healthy females were presented neutral, pleasant, and unpleasant images from the International Affective Picture System while standing on a stabilometric platform and wearing a polar band to assess body sway and heart rate. In the total sample, only unpleasant pictures elicited reduced body sway and reduced heart rate (freezing). Moreover, participants who had experienced 1 or more aversive life events showed greater reductions in heart rate for unpleasant versus pleasant pictures than those who had experienced no such event. In addition, relative to no-event participants, single-event participants showed reduced body sway to unpleasant pictures, while multiple-event participants showed reduced body sway in response to all picture categories. These results indicate that aversive life events affect automatic freezing responses and may indicate the cumulative effect of multiple trauma. The experimental paradigm presented is a promising method to study freezing as a primary defense response in traumarelated disorders.
