Who created/established Expectancy Theory?
Victor Vroom (1964)
What four elements are involved in Victor Vroom’s Expectancy Theory?
Motivational Force
Expectancy
Instrumentality
Valance
What is Motivational Force, in relation to Expectancy Theory?
The likelihood that an individual will engage in a particular action. As the motivational force increases so does the likelihood of engagement in action.
What is Expectancy, in relation to Expectancy Theory?
The belief that an increase in effort will produce an increase in performance.
What is Instrumentality, in relation to Expectancy Theory?
The belief that an increase in performance will produce an increase in particular outcomes.
What is Valance, in relation to Expectancy Theory?
How much a particular outcome is desired - how much does a person care about a specific outcome.
What is the formula of Expectancy Theory?
Motivational Force = Expectancy x Instrumentality x Valance
Looking through the lens of Expectancy Theory, how can we motivate people?
Tailor rewards to reflect an individual’s interest, as motivation levels are directly linked to how desirable an outcome is for a person.

How does marijuana affect the brain?
Dopamine - GABA secreted into synaptic gap. - reduces dopamine secreted into the synaptic gap. GABA is inhibitory - dopamine neurons adjust dopamine secreted.
Endocannbinoid - a neurotransmitter - can cause an increase in the release of GABA and other neurotransmitters that affect the amount of dopamine released.
Cannabis contains cannabioids - THC - very similar to endocannabinoid. When use cannabis, THC chemicals travel to the brain and compete with endocannabinoids to bind to protein receptors on neurons involved in dopamine production. THC causes GABA secretion to reduce, and therefore dopamine to rise = increased dopamine give high - however, THC affects normal working of the brain and body.
