Measurement models for reaction time tasks in Study 1 and standardized parameter estimates. (a) Model A including a general reaction time factor. Model fit: χ2[df] = 151.76[20], p < .01, CFI = .75, RMSEA = .22, SRMR = .12. (b) Model B with a nested factor reflecting the effects of the instruction (speed vs. accuracy). Model fit: χ2[df] = 47.17[16], p < .01, CFI = .94, RMSEA = .12, SRMR = .06. (c) Model C with an additional nested factor reflecting binding costs in arbitrary conditions. Model fit: χ2[df] = 19.92[12], p = .07, CFI = .99, RMSEA = .07, SRMR = .04. Models only included indicators of reaction time in the arrow and shape tasks because no consistent stimulus-response compatibility effects were found in the word task. Model B fit the data better than Model A and Model C fit the data better than Model B. N = 135, * p < .05.
