TY - JOUR PY - 2011// TI - Response-level probability effects on reaction time: Now you see them, now you don't JO - Quarterly journal of experimental psychology (2006) A1 - Katzner, Steffen A1 - Miller, Jeff SP - 865 EP - 886 VL - 65 IS - 5 N2 - Many reaction time (RT) experiments have tested for response-level probability effects. Their results have been mixed, which is surprising because psychophysiological studies provide clear evidence of motor-level changes associated with an anticipated response. A survey of the designs used in the RT studies reveals many potential problems that could conceal the effects of response probability. We report five new RT experiments testing for response-level probability effects with the most promising of the previous designs-that of Blackman ( 1972 )-and with new designs. Some of these experiments yield evidence of response-level probability effects, but others do not. It appears that response-level probability effects are present primarily in simple tasks with a strong emphasis on response preparation, possibly because participants only expend effort on response preparation in these tasks.
