Different versions of this theory appeal to different sets of stimuli that might be used to guide the pigeon home.
Through integration of these two sets of stimuli, the central nervous system continuously adjusts the contraction of the motor units (e.g., muscles) to obtain the desired orientation.
They used two sets of stimuli.
Different versions exist but, in general, participants are provided with different sets of stimuli (e.g. animal pictures).
Eighteen schizophrenia patients and one group of healthy age- and gender-matched controls viewed identical sets of stimuli.
Physiological messages to cells are encoded in the magnitude, and in the time- and space-contingencies, of sets of stimuli.
In Experiment 1, we manipulated low-level features of emotional faces to create five sets of stimuli that ranged from photorealistic to fully iconic.
If transfer of training would take place, or in case of the control group with no training at all, similar results would be expected for both sets of stimuli.
The version of the Stroop task we used (Cepeda, Blackwell, & Munakata, 2013) involved three sets of stimuli: (1) non-color words (i.e. words that do not refer to colors) printed in red, orange, yellow, green, blue, or purple (e.g. the word "advice" printed in blue ink).
