Predicting Fluid Intelligence by Components of Reaction Time Distributions from Simple Choice Reaction Time Tasks
Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests. To further explore this relationship and to examine its generalizability to a sub-adult-aged sample, we administered different choice RT tasks and Cattell’s Culture Fair Intelligence Test (CFT 20-R) to n = ...
متن کاملReliability of an interactive sport-specific choice reaction time device
Methods Twelve recreationally trained males participated in Part a, which consisted of two visits (mean +/SD, 3.7 +/1.3 days); a familiarization testing day (V1a), followed by a subsequent testing day (V1b), and was conducted over a three week investigation period (28 +/5 yr, 178 +/9 cm, 79.15 +/15.7 kg, 17.5 +/6.6 % body fat). Part a was composed of nine choice reaction time testing protocols,...
متن کاملSome experiments on simple and choice reaction time.
4 experiments in simple and choice reaction time (RT) are reported. Experiment I examines the effect of monetary payoffs on the accuracy and variability of time estimation. Experiment II examines the effect of moving the position of a narrow payoff band along the time axis on the variability of observed RTs. This appears to alter the proportion of bona fide reactions (of low variability) and of...
متن کاملAnticipatory postural adjustments under simple and choice reaction time conditions.
Two different schemes of the central organization of anticipatory postural adjustments (APAs) have been proposed: one of them assumes that postural and focal components of an action are results of a single control process (single-process hypothesis) while the other one suggests that these two components result from two relatively independent control processes (dual-process hypothesis). To disti...
متن کاملA choice reaction time analysis of spatial frequency discrimination.
Simple reaction time to the onset of sinewave gratings was measured as a function of spatial frequency in two observers. These results are compared to the choice reaction time required for the observer to correctly discriminate the spatial frequency of two gratings flashed sequentially. Grating contrast was either 0.75 or 1.5 logarithmic units above the detection threshold for each spatial freq...
