Inhibition of return(IOR) refers to a deterimental consequence of exogenously oriented attention. Would the effect be diminished or increased by endogenously oriented attention? Using both exogenous (brightening of peripheral box) and endogenous (cental arrow) cue, Exp.1 showed that IOR was diminished at the endogenously attended location. Using peripheral '<' and '>' signs, Exp.2 tested whether the result of Exp.1 was due to the complicaed nature of double cue. Surprisingly, IOR was not affected by the endogenous orienting.
