Effects of sound intensity on a midlatency evoked response to repeated auditory stimuli in schizophrenic and normal subjects.

abstract：:The effect of cardiac cycle time on attentional selection was investigated in an experiment in which participants classified target letters in a visual selection task. Stimulus onsets were aligned to the R wave of the electrocardiogram and stimuli presented either during the ventricular systole or diastole. Selection ...
