Dual-process theory of instrumental action
Idea that there are 2 action systems
1. goal directed system: top-down, flexible cognitive control system
2. habituation-based system: bottom-up, automatic, efficient reflexive system.
Belief criterion in goal-directed behaviour
Performance is mediated by a representation of the causal relationship between the action and its outcome
goal directed behaviour
= instrumental behaviour that is only performed when one has a certain goal and believes that this behaviour will increase the likelihood of reaching that goal.
Mediated by cognitive belief criterion & motivational desire criterion
Instrumental behaviour
Behaviour that is learnt as a result of knowledge of an R-O relationship
Habit based action
Instrumental behaviour that is triggered by contextual stimuli, independent of the current motivation for the outcome
Thorndike‘s Law of Effect
Habits are formed when a behaviour is followed by reward (positive reinforcement) or by absence of an expected negative event
S-R association
Which classical experimental paradigm is used to determine whether a certain behaviour is goal-directed or habitual?
The outcome-revaluation/devaluation test
Phases of outcome-revaluation
- instrumental learning
- outcome devaluation
- critical test
Instrumental (operant) conditioning
Change in behaviour caused by a relationship between an instrumental response (R) and a motivationally relevant outcome (O; reinforcement or punishment)
Instrumental behaviour can be goal directed or habitual
Habit theory of substance abuse
Idea that aberrantly strong habits (+ impaired cognitive control) mediate the transition from goal-directed, recreational substance use towards compulsive substance abuse)
-> habituation based system
-> goal-directed system
Why do individuals with drug addiction continue to use drugs or alcohol despite being aware of the harmful consequences?
- aberrantly strong cravings (and incentive sensitization)
- aberrantly strong habits
- impaired cognitive functions
Mesolimbic pathway
Going from the ventral tegmental area (VTA) to the nucleus accumbens and responsible for craving through reward and salience processing
Nigrostriatal pathway
Going from substantia nigra to the posterior putamen and responsible for habit-formation
Mesocortical pathway
Going from VTA to PFC and responsible for cognitive control functions
