Putting aside the fact that any causal inference from physiological factors to (largely) normative, discrete, categories like language types is problematic per se, what our results show is that the phonological quantity system in Finnish is not based on (the perception of) duration alone, but that both pitch and durational information in fact codetermine the length opposition.
In addition to primitive sensations to the noise source-loudness, pitch and timbre-perception of duration is introduced here as a fourth.
Direct, unitary perception of duration occurs up to a maximum period of approximately 1.5 to 2 seconds from the beginning to the end of a continuous sensory stimulus.
Indeed, expectation has no duration, whereas the perception of duration is the outcome of an expectation.
Second, we addressed whether visual (auditory) inputs could alter the perception of duration of auditory (visual) inputs.
These results support the existence of multisensory interactions in the perception of duration and, importantly, suggest that vision can modify auditory temporal perception in a pure timing task.
We used prospective duration judgments within and across sensory modalities to examine the effect of stimulus predictability and feature change on the perception of duration.
One experience of time is the perception of duration, which is not isomorphic to physical duration and can be distorted by a number of factors.
We thus suggest that the contextual salience of the stimuli is a critical factor for the perception of duration at this time-scale, a feature that could be incorporated in models of multisensory and time perception.
Studies comparing the perception of duration across sensory modalities have shown that the duration of an auditory interval is often judged as longer than the same interval presented in the visual sensory modality [22], [23], [24].
Such medications can alter the perception of pain as well as the perception of duration and also aim at reducing anxiety.
