Answers
Answer:
Although response enhancement and resistance to habituation
Answer:
The effects of shifting attention toward or away from visual or auditory stimuli of varying intensities were studied using average evoked responses (AERs) in 24 normal human volunteers. Ss were asked to attend to visual or auditory stimuli of four intensities (randomly presented) or to ignore the lights and tones and do mental arithmetic. For visual stimuli, attentional effects were largest at low intensities whereas for auditory stimuli equal effects were shown across intensities. Similar individual rates of increase of AER amplitude with increasing intensity were observed for both visual and auditory stimuli when attentional conditions were controlled.
These results suggest that some general intensity processing response is reflected in the AER and that it is important to control attention in AER experiments.
