Explanation of Major Hypothesis: The researchers were hoping to prove through their experiment that context-processing abilities are severely hampered by cocaine use and abuse. Scientists have shown the negative effects of drug use on mental processes and these researchers wanted to more closely examine what is considered higher-order thinking. Context processing refers to the mental process which allows an individual to act and understand their environment and to understand their place within that environment, i.e. their specific context within a location, as well as how they can function within this location. Research Methods: Two studies were conducted to determine the cognitive abilities of cocaine abusers. Two groups, one of cocaine users and one which did not use drugs were both tested and their results directly compared to find out what link if any there was between context processing and cocaine use. The first study used an expectancy variable measuring the AX task. These tests were designed specifically to test the impairment to mental processes which require "bottom-up perceptual and encoding processes" (Jones 2013, page 1). The
