The hаbit theоry оf аddictiоn proposes thаt the transition to addiction involves a shift from goal-directed behavior to habitual behavior. Consider the evidence from the lecture concerning the behavioral evidence for this shift and the brain mechanisms involved. What is the behavioral evidence that drug seeking behavior may become more habitual over time? Be specific about the behavioral manipulation and measurements involved in establishing this, including how habitual and goal-directed behavior are defined behaviorally. (4 points) How do habitual and goal-directed behavior differ in terms of the brain regions or mechanisms that are required? What is the evidence supporting this answer, including the brain manipulation or measurement and the behavioral evidence or effects? (8 points) More recent work indicates that the development of habits does not fully explain the transition to compulsive drug use/addiction. Does habitual behavior rely on brain region(s) or mechanisms that are distinct from or similar to those implicated in compulsive-like (punishment-resistant) drug or alcohol seeking? What is the evidence for your answer? Be sure to describe the specific evidence supporting the role of a brain region or mechanism in compulsive-like drug or alcohol seeking. (8 points)
