However these studies have either grouped subjects according to their sensitivity to heat stimuli [ 38], set stimuli according to individual thresholds [ 11], or used various stimulus intensities [ 37].
In the first contrast set, stimuli were presented at similar cone contrasts in order to match stimuli in terms of their respective cone responses.
The memory set stimuli thus consisted of one (low load) or three (high load) meaningless symbols that were randomly drawn from a pool of 500 different stimuli.
Thus, at least in principle, more information could be extracted from stimuli in stimulus Set B than from stimuli in stimulus Set A. Each set of stimuli was presented in two blocks of 200 stimuli each (100 real-world objects and 100 non-sense objects).
In total, we used two sets of four face stimuli each: stimulus set 1 for two participants and stimulus set 2 for four participants.
The behavior modification component, primarily facilitated by the dietitian, used techniques such as self-awareness, goal setting, stimulus control, coping skills training, cognitive behavior strategies, and contingency management.
Techniques taught to youth and family members include self-awareness, goal setting, stimulus control, coping skills training (CST), cognitive behaviour strategies and contingency management.
As with the "beauty" stimulus set and the IAPS stimulus sets, no coherent patterns (i.e., structures) were observed between location measures of positive (approach) and negative (avoidance) keypressing to food stimuli.
Examples for stimuli from stimulus Set A are shown on the left side of Figure 1.
