high quality stimuli

According to Mace and Belfior(1990) in their research study, titled Behavioral Momentum in the Treatment of Escape-Motivated Stereotypy, it was concluded and recommended that, instead of using high-p request strategies, a high value reinforcer should be used to increase compliance if motivation for escape behavior is high. This high value reinforcer is referred to as HIGH QUALITY STIMULI in the research study.
