“…The result, confirmed by later experiments that controlled the speed accuracy tradeoff using responsedeadlines at various set-sizes (Pachella et al, 1968;Pachella & Fisher, 1972), is that Eq. (7) holds also for speeded responses.…”

“…In 1952, Hick [7] reported that RL was linearly related to (Ht), a finding replicated by Brainard et al [8] and Pachella et al [9], Subsequently, H, has proven to be the single best predictor of response latency [10]. Of greater pertinence for this study were demonstrations that: (1) errorless and error containing perfor mances are described by the same linear func tion [11], and (2) that response latency can be decomposed into the temporal sum of input, central processing, and response output [12], These facts make it possible to study the effect of information load on the components of RL among groups with widely differing accura cies.…”

Subjects performed a signal discrimination task under four conditions: normal pace, accuracy, speed, and SATO (equal effort to speed and accuracy). Characteristically, schizophrenics demonstrated decreased accuracy, poorer compliance, increased total response time, and increased simple reaction time. Surprisingly, central processing time (decision time) was equivalent. Analysis of processing resource allocation identified significant group differences only under the SATO condition. Here, controls balanced attentional resources but patients worked almost exclusively for speed. Under conjoint performance conditions, patients apparently minimize categorical processing time at the expense of accuracy. These data are interesting as they identify specific circumstances under which schizophrenics manifest an attentional deficit.

“…Conversely, a fast-driving style is likely to become more cautious with a sudden storm. Although these processes do not occur very often in reallife, they are critical in many situations, and they can be studied in a controlled lab-setting, where strategic control can be effectively used to flexibly and continuously switch between rapid and accurate decision-making depending on payoffs [Swensson, 1972], deadlines [Pachella et al, 1968] and instructions [Hale, 1969].…”

Switching between rapid and accurate responses is an important aspect of decision-making. However, the brain mechanisms important to smoothly change the speed-accuracy strategy remain mostly unclear. This issue was addressed here by using functional magnetic resonance imaging (fMRI). On each trial, right-handed healthy participants had to stress speed or accuracy in performing a color discrimination task on a target stimulus according to the instructions given by an initial cue. Participants were capable of trading speed for accuracy and vice versa. Analyses of cue-related fMRI activations revealed a significant recruitment of left middle frontal gyrus and right cerebellum when switching from speed to accuracy. The left superior parietal lobule was activated in the same switching condition but only after the target onset. The anterior cingulate cortex was more recruited, also after target presentation, when speed had to be maintained from one trial to the next. These results are interpreted within a theoretical framework that attributes a role in criterion-setting to the left lateral prefrontal cortex, perceptual evidence accumulation to the superior parietal lobule, and action energization to the anterior cingulate cortex, extending previous findings to the domain of speed-accuracy tradeoff regulations.
