Luce (2002) , under the condition that respondents' numerical distortion function and the psychophysical functions could be separated, formulated a behavioral ...
Gable and Harmon-Jones [2] (Experiment 2) used a neutral picture (e.g. rocks) or a high motivational intensity picture (e.g., dessert) appeared followed by the Navon letter task [14] to measure attentional scope.
