Abstract

Mismatch negativity is a component of the auditory event-related
potential which is elicited by stimulus change following a series of
homogenous stimuli. Mismatch negativity is the subject of some
debate regarding whether physical stimulus features are
processed and mismatch detection conducted equally well,
whether in the presence or absence of attention. Alcohol and
temazepam are both drugs which have been found to attenuate
other attention dependent components of the ERP. This
attenuation is attributed to a reduction of attentional resources.
Thus by measuring the effect of attention upon mismatch
negativity under the influence of alcohol and temazepam singly,
this dilemma may be resolved. If temazepam and alcohol only
affect attentional components of the ERP then attenuation would
only be expected in ERPs taken in conditions of attention.
Furthermore if MMN is attention dependent it would be expected
that these drugs administered together may produce an
interactive effect upon the amplitude of mismatch negativity.
