Description
Motivation  To be moved  Single and multiple causes (ie; why we eat)  Involuntary and voluntary motivators Emotion (why motivation theorists today are interested in understanding feelings)  Negative feelings can and often do undermine goal directed behaviour while positive feelings can and often do sustain goal-directed behaviour Instincts  They are inherited impulses that result in specific pattern of behaviour  We can change in order to be able to deal with environmental pressures more efficiently  Main people are Darwin and Freud  Biologists use the word instinct to refer to the belief that there is an innate or biological basis for adaptive behaviour  Psychologists have largely abandoned it-didn’t help predict what will happen next  McDougal was important in development of initial instinct theory Darwin/ Theory of Evolution  Said that we are constantly going under biological structural changes as a result of environmental pressures  Principle of Variation: trait variation within a population  Principle of natural selection environment selects trait that aids survival  Natural selection: members of a species with physical or behavioural attributes that allowed them to better deal with environmental pressures would survive and reproduce and as a result they would pass along this biological structure to their offspring; on the other hand, those that could not survive would not be able to reproduce, and thus their biological structure would be lot over time  Darwin’s contribution was not the discovery of evolution, it was that natural selection is the mechanism by which evolution occurs Freud  ID: impulses; devil; over development would lead to disregard of all others o Responsible for 4 F’s  Fight  Flight  Food  Fornication o Unconscious o Response to Pleasure Principle:  Superego: morally right; ideal; angel; over development would lead to rigid personality  EGO: in middle who is balance btw both  Said our energy comes from libido  Instincts give rise to representations of the goal object Drives  Means same as instincts and needs Needs  Needs theory: we stop addressing threat once our needs are met o Maslow  The idea that needs give rise to action is no longer used; it is that needs give rise to dispositions and whether these dispositions lead to action depends on previous circumstances Maslow  Needs theory  Least supported empirical research but just makes so much sense that people don’t even question it; made up of observations and intuitions  Hierarchy of motives-physiological, safety, love and belongingness, esteem, self- actualization  Flawed because some people may stop and not seek higher goals  Criticism is also that some may occur simultaneously  Some higher needs maybe are met before lower ones (ie travel leads to instability but maybe assist with esteem) Goal Theorists  Set goal which creates tension as you work towards goal and then the tension is released  Goals give rise to action  People adopt different orientations to the environment depending on whether they feel threatened; if threatened they adopt an ego orientation, otherwise they adopt a mastery orientation Reinforcer (positive and negative)  Negative reinforcement: removal or aversive stimulus o Is better and long lasting then punishment because punishment is immediate and we tend to forget the pain that occurs from punishment o positive reinforcement: reward Growth/Mastery theories  come from our want to master environment  focus has been to uncover the process of mechanisms that guide this tendency to master  assumes the tendency to master develops from a fundamental curiosity or exploratory need Expectancy-Value theory  humans have expectations about outcomes but also that they attach values to these outcomes Arousal  critical for survival  arousal is mobilization or activation in preparation for behaviour  indicator of amount of energy that is being made available  increased arousal=more vigorous performance but its not always more efficient it depends on the complexity skill level and motivation  physiological arousal; ANS (sympathetic is arousal, parasympathetic is preparing for arousal); brain arousal (different areas aroused depending on activity) Approach  Psychological  Do something out of desire  Not always related to specific goal  Hot/cool theory of gratification Hot/cool system  Hot System: LIMBIC o Go, simple, fast, accentuated by stress, emotional  Cool System: FRONTAL o Know, complex, slow, develops late, self-control, attenuated by stress  Separates us from other mammals Avoidant  Do something to avoid something else  Compelling and hard to ignore  Aversive; strong immediate need to distance yourself  Avoid danger o From evolutionary perspective when we sense danger, we have an instinctive need to avoid the threat to our survival void causes Extended Adaptation  Emerging brain knew nothing of cell phones, driving, bikes, etc. Components of Motivation  Motivation is concerned with understanding how dispositions can lead to actions, through the interaction of biological, learned, and cognitive processes Food preferences  21% fat, 8% sugar  combination of innate and learned Hypothalamus  Found in limbic system  Jobs: o Control and integrate ANS o Feelings of rage and aggression o Regulates body temp o Regulates food (contains feeding center and satiety center)  Satiety=feeling content o Contains thirst center waking state and sleeping patterns Prefrontal Cortex  handles emotion, behaviour regulation (difference between right and wrong) has millions of neural pathways that help it communicate with deeper structures of the brain such as the amygdala Neurotransmitters  Involved in regulation of mood  They fit into receptor sites Amygdala  Fear responses, startle, facial recognition  Role in memory and emotional reactions  Almond shaped group of neurons deep within medial temporal lobes  Should work with prefrontal cortex; if they have miscommunication is could lead u to be a serial killer  Highly reactive amygdala means your likely to experience greater negative affect Preparedness Contrapreparedness Mind BIS  Behaviour Inhibition System  Conditioned signals of punishment and non-reward  Activated=arousal to inhibit on-going behaviour BAS  Activated by conditioned signals of rewards and non-punishment  Activated=arousal and increased approach  Born with this or BIS being more dominant but you can teach your brain to prefer one over the other CCK (the Satiety hormone)  Hormone released after food intake; short term regulation  The fatty acids and glucose enter the small intestine, which triggers the CCK. So once the CCK is triggered, the higher the CCK level the more satiety and fullness
More Less
