Therefore, in these training modes, the presentation duration of each auditory stimulus was substantially longer than that of the stimuli in the modes Prose and Melody.
Before moving on to other methodological differences, it should be noted here that even the presentation duration of the visual targets can modulate the contextual effects observed (Ahrens 1998, 2006).
When the presentation duration was shorter than 1000 milliseconds (for example, 300 milliseconds in Ahrens 1998, and 300 and 750 milliseconds in Ahrens 2006), exhaustive access of ambiguous meanings has been observed.
Due to differences in level of performance – these trials for deaf subjects were performed at briefer presentation durations than for hearing subjects –identification accuracies were normalized as a function of the presentation duration for those trials to yield a measure of central task accuracy per millisecond of presentation duration.
Tasks procedures were almost identical to Experiment 1 with the difference that we illuminated only one stimulus at a time and the presentation duration was shorter (250 ms).
Interestingly, this location specificity broke down when the motion speed was reduced to speeds of 3.6°/sec, suggesting that the onset bias is sensitive to the presentation duration at any location and not "onset" per se.
Since the time constant of the decay critically depends on the presentation duration of the adapter, which was shorter than in most studies addressing the MAE, we cannot compare our findings with decay times from other studies.
This effect for auditory naming is consistent with previous studies and may be due to the presentation duration of auditory relative to visual stimuli.
The WRT score is defined as the presentation duration at which 50% of the words in a block are read correctly.
Especially in emotion research, the presentation duration appears to be important, not only from a methodological point of view, but also in respect of differences in information processing.
Changes in the presentation duration of acoustic stimuli have been associated with increased activation in both the left [39] and right IFG, with some activation also seen bilaterally in the IFG and in regions of the lateral frontal cortex [14,57,59].
