“…Prior studies of temporal attention effects on the rapidity of late motor processes have obtained either no effect or only a very small one (e.g., Bausenhart, Rolke, Hackley, & Ulrich, 2006;Mu¨ller-Gethmann, Ulrich, & Rinkenauer, 2003;Tandonnet, Burle, Vidal, & Hasbroucq, 2006). The only previous study of visual processing that used a subtraction component to avoid contamination by CNV offset and motor potentials similarly found no variation in the speed of perceptual analysis (Rudell & Hu, 2001). An experiment in monkeys using single neuron recordings of stimulus-and response-related activity found no effect whatsoever on the speed of visual processes (Fecteau & Munoz, 2007).…”

Warning signals can shorten reaction time (RT) via either a top-down mechanism, temporal attention, or a bottom-up one, phasic arousal. The goal of this review article is to identify the locus at which these processes influence RT. Electrophysiological and behavioral evidence indicate that the chronometric locus for both modulatory effects lies mainly within a narrow window at the center of the stimulus-response interval. This interval presumably encompasses late perceptual, response selection, and early motor processes. Phasic arousal is theorized to reduce the threshold for response selection within a circuit involving the supramarginal gyrus. A blind-sight study indicates that conscious, cortical level processing is necessary for temporal attention, at least when the warning signal is visual.

“…This is thought to reflect a more difficult estimation of the timing of the imperative stimulus for longer foreperiods (Klemmer, 1956). LRP studies and psychophysical measurements have yielded evidence for a premotoric locus of the effect (Rolke & Hofmann, 2007;Müller-Gethmann, Ulrich, & Rinkenauer, 2003; but see Rudell & Hu, 2001). Furthermore, animal research has indicated that during the foreperiod interval there is a gradual increase in the firing rate of visual neurons (Ghose & Maunsell, 2002), suggesting that the benefit of temporal preparation is at least in part due to perceptual changes.…”

Abstract& People typically respond faster to a stimulus when it is accompanied by a task-irrelevant accessory stimulus presented in another perceptual modality. However, the mechanisms responsible for this accessory-stimulus effect are still poorly understood. We examined the effects of auditory accessory stimulation on the processing of visual stimuli using scalp electrophysiology (Experiment 1) and a diffusion model analysis (Experiment 2). In accordance with previous studies, lateralized readiness potentials indicated that accessory stimuli do not speed motor execution. Surface Laplacians over the motor cortex, however, revealed a bihemispheric increase in motor activation-an effect predicted by nonspecific arousal models. The diffusion model analysis suggested that accessory stimuli do not affect parameters of the decision process, but expedite only the nondecision component of information processing. Consequently, we conclude that accessory stimuli facilitate stimulus encoding. The visual P1 and N1 amplitudes on accessory-stimulus trials were modulated in a way that is consistent with multisensory energy integration, a possible mechanism for this facilitation. &

“…Median response time for each condition was calculated with the remaining trials for each participant. Median response time was used to limit the impact of individual trials (e.g., Rudell & Hu, 2001). To understand the impact of instruction, response time was analysed regardless of the correctness of the trials.…”

Experiments were conducted to test the impact of embedding mental action verbs within instructions. Experiment 1 examined the instructional effects of these verbs on response time to a visual stimulus. Significant response time differences resulted from instructing participants to engage in different mental actions. Using Multidimensional Scaling, Experiment 2 explored how people understand the relationships amongst mental action verbs, resulting in a single "level of processing" dimension. Experiment 3 was designed to further explore the relationship of these verbs to cognition and behaviour. Signal detection analysis was used to determine if participants were shifting their criterion depending on the level of processing suggested in the instruction. Results showed an effect of instruction on response time, but not on criterion, sensitivity, or accuracy. Response time effects were found that were consistent with differences in word characteristics, including meaning.
