have shown that the emotion processing demand influences RT, delaying RTs to emotion identification vs. gender, age and race identification tasks. In support of the effect being specific to emotion identification, other groups have used degraded stimuli as control stimuli and still found EFE effects (Eimer and Holmes, 2007). We note that although ERPs have a higher sensitivity to group differences than do RT or task accuracy, these behavioral measures are more sensitive to task effects that do not differ between alcoholics and controls.
