“…We predicted that self-rated stress would increase incrementally with task demand. More importantly, we predicted that this increase in stress following the SET manipulation would be accompanied by a reduction in postural sway reflecting a stiffening or freezing response in line with the previous research, (Adkin et al 2000;Azevedo et al 2005;Facchinetti et al 2006;Roelofs et al 2010). These findings would suggest that the reduction in postural sway observed when using postural threat and aversive images can also be induced using cognitively and socially induced stress.…”

“…Using fear-freezing responses in animals as a starting point, freezing has also been assessed in humans using a paradigm comprising passive viewing of aversive or threatening images, for example, images of mutilation (Azevedo et al 2005;Facchinetti et al 2006). Similar to posturalthreat research, these studies showed a reduction in sway, an increase in mean power frequency of sway but also bradycardia, the latter also being associated with freezing responses in animals.…”

Cognitively and socially induced stress affects postural control

Postural control is an adaptive process that can be affected by many aspects of human behavior, including emotional contexts. The main emotional contexts that affect postural control are postural threat and passive viewing of aversive or threatening images, both of which produce a reduction in postural sway. The aim of the present study was to assess whether similar stress-related changes in postural sway can be observed using stress induced by social evaluative threat (SET) while performing arithmetic tasks. Twelve young adults performed an arithmetic and a postural control task separately, concurrently, and concurrently with added time pressure in the arithmetic task. In the final condition, participants were given negative feedback about their performance in the arithmetic task and performed it again while being observed (SET condition). Results showed that stress increased linearly with task demand. Postural sway and reaction times were not affected by the first two conditions; however, when time pressure was introduced, reaction times became faster and sway amplitude increased. Finally, introduction of SET caused the predicted reduction in postural sway and an increase in reaction times relative to the time pressure condition. Our results suggest that stress induced using a combination of arithmetic tasks and social evaluative threat leads to systematic changes in postural control. The paradigm developed in the present study would be very useful in assessing interactions between cognition, stress, and postural control in the context of postural instability and falls in older adults.

“…These data suggest that the beneficial effects of an external focus of attention and the associated heart rate deceleration could be influenced by changes in anxiety level. Facchinetti, Imbiriba, Azevedo, Vargas, and Volchan (2006) found that, while watching aversive pictures, a freezing-like reaction occurred in postural stability and this was accompanied with heart rate deceleration. This heart rate deceleration must be understood in the initial attentional nature of defense.…”

Preparatory heart rate deceleration occurs in tasks with an external focus of attention and is often assumed to facilitate balance performance. However, its effects upon sport-related complex balance movements have not been studied. Heart rate patterns during the preparation period of an acrobatic element (flic-flac) on the balance beam were studied in 14 female gymnasts (M age 13.2 years). A significant heart rate deceleration was found in attempts with a fall in the consecutive acrobatic element, but not in attempts without a fall. These data suggest that preparatory heart rate deceleration may be detrimental to the performance of complex movements on the balance beam.

“…Diversos trabalhos científicos (FACCHINETTI, 2006;CARPENTER, 2009;PEREIRA, 2006;WILLIAMS, 2008) têm demonstrado a eficácia da utilização de mensagens e imagens amedrontadoras para promover repulsa. Tais mensagens têm potencial de gerar uma associação negativa entre a embalagem e, por conseguinte, seu produto.…”
