Preparatory state and postural adjustment strategies for choice reaction step initiation
2016, NeuroscienceCitation Excerpt :In addition, accumulating evidence supports that a LAS reduces RTs irrespective of any startle reaction, (e.g., Valls-Solé et al., 1995; Reynolds and Day, 2007; Nonnekes et al., 2013, 2014), warranting further investigation of its necessity. Intersensory facilitation, where the presentation of multiple sensory stimuli results in RTs that are shorter than those resulting from a single sensory stimulus (Nickerson, 1973; Schmidt et al., 1984), may have partially accounted for the shortening of RTs. However, our previous study, which examined the effects of an auditory stimulus (80 dB) presented occasionally and concurrently with a visual imperative stimulus on a stepping response, revealed that an auditory stimulus of 80 dB had no effect on APA errors in a CRT task (Watanabe et al., 2015).
Evidence for a response preparation bottleneck during dual-task performance: Effect of a startling acoustic stimulus on the psychological refractory period
2013, Acta PsychologicaCitation Excerpt :This may seem surprising, as we have indicated that the lack of triggering by the SAS is indicative of serial processing, which may lead to the expectation that startle and control trials be performed at a similar latency. However, it is well known that pairing a visual stimulus with an accessory auditory stimulus will decrease RT via a process known as intersensory facilitation (Nickerson, 1973; Schmidt, Gielen, & van den Heuvel, 1984), with greater facilitation accompanying a more intense stimulus. Given the high intensity acoustic stimuli (119 dB) accompanying the visual stimulus, it is not surprising that RT was facilitated in this situation.
Mindfulness meditation associated with alterations in bottom-up processing: Psychophysiological evidence for reduced reactivity
2010, International Journal of PsychophysiologyCitation Excerpt :Since the different processing stages of the visual spatial cue were not manipulated in the current experiment, the exact locus of the difference in IF effects between groups could not be determined. According to what seems to be the most suitable view to explain IF effects, i.e., the preparation-enhancement view, the auditory accessory has an alerting or arousing role that may alter processing in a number of stages (Schmidt et al., 1984). Thus, it would be interesting for further research to investigate which specific processing stage(s) are affected by MM, resulting in the attenuated IF effects.
