This roughly two-second maximum for directly perceived duration seems to have a biological basis and can be considered the upper temporal limit of some sort of integrated neural mechanism.
The specific cost-cutting channels depend on the intensity and perceived duration of the shock as well as on product and labour demand constraints.
Does immediate repetition shorten perceived duration?
Moreover, local adaptation of the visual field reduces the perceived duration for stimuli presented to the position of the adapting stimuli [8], whereas we observed an increase of the perceived duration with the inanimate characters.
The point of subjective equivalence (PSE) at 50% of the psychometric function estimates the perceived duration of the standard stimulus.
These results establish that the subjective dilation of perceived duration occurs even when the target is predicted and expected.
The same authors [5] showed that lateralised presentation of visual stimuli biased their perceived duration according to the side of space where they were encoded.
First, we found robust distortions of perceived duration in auditory, visual and auditory-visual presentations despite the predictability of the feature changes in the stimuli.
In other words, the neural response to the successive stimulus in an ordinal sequence would be suppressed, thereby contracting its perceived duration.
For example, simply reducing the visibility or increasing spatial frequency of visual stimuli induces dramatic compressions in their perceived duration [17].
We next address whether salient standards such as looming-stimuli would induce a distortion of perceived duration in a steady target.
