Auditory Reaction Time and Visual Reaction Time in Asymptomatic HIV
2023Background: Auditory reaction time and visual reaction time were measured in asymptomatic HIV positive persons and corresponding controls to detect impaired central information processing mechanisms in the early stages of HIV. Objective: To perform auditory reaction time and visual reaction time in asymptomatic HIV positive persons and corresponding ...

Auditory evoked response and reaction time
Electroencephalography and Clinical Neurophysiology, 1967Abstract Ten human subjects listened to auditory “clicks” coming in runs of 50, the inter-click intervals varying randomly between 1 and 3 see. In some runs the subjects ignored the clicks, in others they responded to each click as quickly as possible by pressing a key. Incentive was varied in the responding runs by payment at a flat rate or based on

Correlation between Auditory Reaction Time and Intelligence
Perceptual and Motor Skills, 1986Discriminative reaction times to auditory stimuli were measured for 150 students of the local Chinese population. Pearson's correlation with scores on the Standard Progressive Matrices and RTs was negative, becoming −0.30 when slower trials were eliminated.

Auditory reaction time and absolute threshold in cat
The Journal of the Acoustical Society of America, 1977Reaction time and absolute thresholds for acoustic stimuli were measured in cats using an operant reaction-time procedure in conjunction with titration methodology. The reaction-time/titration procedure incorporated a self-paced feature and utilized a photobeam operandum developed for the cat.

Evoked Potentials and Auditory Reaction Time in Monkeys
Science, 1969Monkeys with bipolar stimulating and recording electrodes in primary auditory cortex were trained to release a key to the onset of a pure tone. Substitution of direct cortical stimulation for the pure tone resulted in a reduction of 15 milliseconds in the latency of the behavioral response.

Auditory evoked potentials, motor potentials and reaction time
Electroencephalography and Clinical Neurophysiology, 1971Abstract Evoked potentials from simple and choice reaction time (RT) tasks were determined separately for trials in the fast, middle and slow thirds of the RT distributions. We found that those trials with faster RT also produced a more negative N1 peak, less negative peak at N2 and N3 and more positive peaks at P3 and P4; the choice task also ...

Visual–auditory interaction in saccadic reaction time: Effects of auditory masker level
Brain Research, 2008Saccadic reaction time (SRT) to a visual target tends to be shorter when auditory stimuli are presented in close temporal and spatial proximity, even when subjects are instructed to ignore the auditory non-target (focused attention paradigm). Observed SRT reductions typically range between 10 and 50 ms and decrease as spatial disparity between the ...

Apparatus for measuring auditory reaction time
The Journal of the Acoustical Society of America, 1985Apparatus is disclosed for measuring an athlete's auditory reaction time, and for training an athlete to reduce his auditory reaction time in response to an auditory stimulus used to initiate an athletic event. The apparatus automatically provides a sequence of variable time delays followed by auditory stimuli which stimulates the sequence and auditory

Ultradian Rhythms in Auditory Reaction Time
1985The identification of a 90-100 min rhythmicity in sleep parameters — rapid eye movements, body motility and EEG (Aserinsky and Kleitman, 1953; Dement and Kleitman, 1957) — which persist when sleep is consumed during the light span, suggested to Kleitman (1963) that this cycle could be a fraction of a more generalized oscillatory phenomenon, acting both
