What does motivation study?
What starts behavior
How is behavior sustained over time
Why is behavior directed toward some ends but away from others?
Why does behavior change its direction
Why does behavior stop
Why does it change in energy.
What is motivation?
The processes that give behavior its energy and direction
direction in motivation
behavior that is aimed towards achieving a particular purpose or goal.
Energy in motivation
behavior that is relatively strong and persistent.
needs
The conditions within an individual that are both essential and necessary for the maintenance of life, nurturance of growth and well being.
Needs generate wants and desires
Needs can be physical or psychological
Emotions
Emotions are short-lived subjective. They orchestrate and organize four different aspects of experience:
- Feelings; subjective verbal descriptions of emotional experience
- Physiological preparedness; how our bodies physically mobilizes itself to meet situational demands
- Expression; how we communicate our emotions publicly to others
- Emotions allow us to anticipate and to react adaptively to important events in our lives.
What does the phrase grand theory refer to?
an all-encompassing theory that seeks to explain the full range of motivated action-why we eat, drink, work, play, compete, fear certain things, read, fall in love…….. why we do shit.
Drive
The psychological discomfort resulting from a biological deficit.
Drive theory view that behavior was motivated to the extent that it served the needs of the organism and restored a biological homeostasis.
The function of behavior is to service bodily needs
The two most widely accepted models of Drive were proposed by Freud and Hull
Drives emerge from bodily needs
Drive energizes behavior
Drive reduction is reinforced and produces learning.
What were all of the grand theories of motivation?
Drive: behavior was motivated to the extent that it served the needs of the organism and restored a biological homeostasis.
(Frued, Hull)
Will: The ancient philosophers understood motivation within the two themes (rational: will; primitive and impulsive: bodily desires)
(Aristotle; Descartes)
Instinct: Physiological analysis of motivation by focusing on the mechanistic. The appeal of instinct doctrine was its ability to explain unlearned behavior that had energy and purpose
(Darwin was the foundation, William James: Pioneered instinct)
(i.e., goal-directed biological impulses).
It started with will (Aristotle; Descartes) then moved to Instinct and finished with Drive.
A SUMMARY OF FREUD’S DRIVE THEORY
Source (A bodily deficit occurs) > Impetus (bio deficit grows & emerges into consciousness as a psychological discomfort, which is anxiety)»_space; Object (to reduce anxiety & satisfy deficit, the person searches out & consumes a need satisfying environmental object (food) > Aim (If the environmental object successfully satisfies the bodily deficit, satisfaction occurs & quiets anxiety, at least for a period of time)
Hull Drive theory (what was different?)
What was so outstanding about Hull’s theory? What made it revolutionary?
Main difference from Freud was Hulls theory
believed Motivation could be predicted before it occurred. With both the instinct and the will, it was impossible to predict in an a deductive fashion when and whether or not a person would be motivated.
What was wrong with the grand theories?
Will: Turned out to be a dead end that explained very little about motivation, as it actually raised more questions than it answered.
Instinct: dead end as well, as it became clear that “naming is not explaining.”
Drive: Limited in scope, and with its rejection grand theories in general. Several additional grand motivational principles emerged with some success (incentive and arousal).
What directly led to the grand theory of instinct - what single scientific discovery led to this?
Darwinism (evolution)
What causes hunger? (i.e: what part controls initiation, what hormone stimulate feeding behavior?)
The bodily organ that monitors level of blood glucose is the liver, and when blood glucose is low, the liver sends an excitatory signal to the lateral hypothalamus (LH), the brain center responsible for generating the psychological experience of hunger (Via the hormone Gherelin). Stimulation of the LH is important, because its stimulation will lead animals to overeat and, if stimulation is continued, to obesity.
(Need, Drive)
What inhibits feeding behavior (what brain structure, hormones, terminology) inhibit feeding behavior?
The brain structure involved is the ventromedial hypothalamus (VMH). Acts as the brain’s satiety center—that is, the VMH is short-term appetite’s negative feedback system. VMH gets stimulated by the liver’s detection of high Cellular glucose. Insulin (hormone) is needed to increase permeability of glucose to send a signal to VMH which signals the production of Leptin.
(Homeostasis, Negative feedback)
Medial forebrain bundle
large collection of pathway-like fibers that connect the hypothalamus to other limbic structures. The “pleasure center” of the brain.
Approach-Oriented
Reticular Formation
plays a key role in arousal and in the process of awakening the brain’s motivational and emotional concerns. (mouse)
Dopamine release and incentives
Incentives (stimuli that foreshadow the imminent delivery of rewards) triggers dopamine release.
Stimuli that foreshadow the imminent delivery of rewards — pleasurable thought.
Example - Kush, smelling Kush, or just thinking about Kush.
What hormone regulates the tend and befriend response?
Oxytocin
What is the master gland?
Pituitary Gland
What controls the master gland?
Hypothalamus
What are the different types of needs?
Physiological, Psychological, Implicit (social)
What is homeostasis?
The bodies tendency to maintain internal state. Homeostasis is the bodies ability to return to its’ basal state
What mechanism do we use to maintain homeostasis?
Negative feedback
