Question

what do you think your experience of the stimule would be like if you had no sensory memory​

Answer 1

Answer:

Sensory memory is a relatively automatic form of memory and has a duration of several seconds. In the auditory modality sensory memory is important for the perception of speech and various aspects of auditory scene perception. The mismatch negativity (MMN) is an ERP that has been extensively used to study sensory memory (Figures 1(c) and 1(d)). The MMN is elicited by a stimulus that deviates from a previously established pattern of stimuli presented sequentially. The rationale for its use is that sensory memory can be probed by first establishing a standard sensory memory representation and then presenting a stimulus that is predicted to differ from the sensory memory representation in some respect. If the MMN is elicited, it can be inferred that the deviant aspect of the stimulus was not a property of the standard stimulus representation (mismatch). It is a way to infer memory representations by defining the ‘limits’ of the sensory memory representation, after which a stimulus is considered different.

Studies of the MMN in normal aging consistently report that when the deviant stimulus differs from the standard in terms of acoustic properties such as frequency or intensity, there are little or no age differences. However, if deviant stimuli differ in terms of timing, such as stimulus duration or interstimulus interval, then age differences are often evident, with smaller MMN amplitudes in older compared to young subjects.
