Sentence examples for ms and stimulus from inspiring English sources
The duration of each circle was 400 ms and stimulus onset asynchrony was 500 ms.
The stimuli consisted of 250 Hz sinusoidal waveforms displayed at a fixed amplitude in various combinations of duration (0, 30 or 300 ms) and stimulus onset asynchrony (0 or 30 ms).
Stimulus duration was 24 ms and stimulus onset asynchrony was 36 ms (see Figure S2).
The duration of each circle was 400 ms and stimulus onset asynchrony was 500 ms or 1000 ms. For half of the subjects, the onset of the leftward circle was synchronized to a tone burst of high (2 kHz) frequency and the rightward circle to a low (500 Hz) frequency tone.
The duration of each circle was 400 ms and stimulus onset asynchrony (SOA) was 500 ms. The onset of the rightward circle was synchronized to a tone burst of high (2 kHz) frequency and the leftward circle low (500 Hz) frequency for three observers.
In each block, the delay in the Stimulus Onset Asynchrony (SOA) and the order of the two tasks changed pseudo randomly from trial to trial, sampling the SOA values {100, 250, 400, 600, 800, 1000, 1250} ms and stimulus presentation orders {Number First, Tone First}.hus, there were a total of 14 trial types which were repeated three times within one block (see Figure 1A).
The fast presentation of the cue (67 ms) and stimuli (40 ms) precludes saccadic eye movement, permitting a measure of exogenous covert attention.
Retrieval trials (Fig. 1C) consisted of a sequence of pre-stimulus (1,000 2,000 ms), stimulus (1,000 ms), and post-stimulus (1,000 ms) periods.
The inter stimulus interval [ISI] lasted 2000 ms and for stimulus presentation and synchronization, the Software Presentation®, (Version 0.71; Presentation Software, Neurobehavioralsystems Inc., CA) was used.
Stimulus exposure time for each picture was 750 ms and the stimulus onset asynchrony was 1500 ms. A fixation cross was presented during the inter-stimulus intervals.
To compare the results of the MEG measurements with the scale values of the subjective preference, combinations of a reference stimulus (Δt1=0 ms) and test stimuli (Δt1=0, 5, 20, 60, and 100 ms) were presented alternately 50 times, and the MEGs were analyzed.
