Abstract

An experiment was conducted to evaluate the effect of order of reporting stimulus dimension in multidimensional stimulus identification using switch task paradigm. Nine healthy participants were required to identify each two-dimensional symbol by pushing the corresponding buttons on the keypad. The two orders of report were Order Color/Shape and Order Shape/Color. There was a task cue prior to each presentation of a symbol indicating the particular report order the participants should perform. The cue changed randomly. Results showed that order of report had a significant effect on response time for the first and second dimension. Analysis of behavioral data showed switch cost indicated by increase in response time was greater for Order Shape/Color, a less appropriate order of reporting dimensional values, than Order Color/Shape. It seemed plausible that participants needed more attention resource and showed more N2 inhibition for Order Shape/Color than for Order Color/Shape which fits the Chinese adjective-then-noun language habit.
