Motivation part 1 Flashcards
Motivation
Why we behave in a certain way
The force that moves organisms to behave the way they do (But it may not result in behaviour)
Motivation:
Has Direction
Approach motivation: the impulse to move toward a stimulus
Avoidance motivation: impulse to move away from a stimulus
Motivation:
Has Intensity
Strength of the urge
From 0 to high level
Motivation:
Is Partially voluntary
Related to behaviour but not the same as behaviour
Often have 2 or more conflicting motivations
Self control: may require choosing long term goal over short term goal
Motivation:
Can be conscious or below awareness
Can be more difficult to put into words than many other psychological states
Subject to rationalisation
Can be done unconsciously
Motivation:
Is Related to emotion
Emotion can be seen as the force behind motivation
- Approach emotions: desire, interest, anger
- Avoidance emotion: fear, disgust
Theories of motivation
Evolutionary approach:
Charles Darwin: connection of evolutionary biology to psych processes
Instincts: unlearned responses to stimuli that is universal to the species
Adaptive: organisms are motivated to engage in behaviours that help them to pass on their genes (reproductive success)
Humans possess high degree of flexibility of behaviour (differences between people)
Theory of evolution
Evolutionary success (mating)
Adaptive tasks like mating, parenting, nutrition, social relations
Not a struggle for survival
Rather it is a race for reproductive success
Key Ideas to Evolution
Variability: differences within a species between each other
- Species with more variability are more likely to survive when environment changes
Heritability: passing on to offspring
Natural Selection
- Viability: live long enough to reproduce
- Fertility: mating success
- Fecundity: number of offspring
Evolved psychological mechanisms
A set of processes inside an organism that
1. Exist in the form they do because they solved specific problems of individual survival or reproduction
- Take only certain classes of input where input
- Can be either external or internal (outside/inside the body)
- Can be actively extracted from the environment or passively received from the environment - Transforms that information into output through a procedure where output
- Regulates physiological activity, provides information to other psychological mechanisms, or produces action
- Solves a particular adaptational problem
Adaptations
inherited and depends on environmental conditions
By-products:
not adaptive
E.g. Whiteness of bones does not solve evolutionary problem
Exaptation
feature now enhances fitness for one function (flying) was originally adapted for different function (warmth)
E.g. feathers for birds were originally for warmth but have now adapted to be for flying.
Spandrels
incidental by-product that became functional adaptation
The brain takes something that is not adaptive and makes it a functional adaptation
Speculated that most functions in the brain are spandrels
Implications for behaviour
There is Continuity between animals and humans
Abandon idea that animals have instincts and humans have minds
Thorndike: Animal intelligence
- Animal behaviour is affected by its consequences (they learn through experience)
- Law of effect
If it does something to create positive consequence it
will keep doing it and vice versa with negative
consequences
Do humans have instincts:
James:
Complex unlearned response to characteristic stimulus
Reflex –> instinct –> learning
All of these 3 things aid us in our behaviour
Instincts
Tendency to act in specific way due to something in the environment.
And the action must come about naturally (not a result of learning)
Variability of behaviour from instinct
Experience can modify instinctive behaviour
Concerning sympathy
Sympathy is most likely an instinct
- List of instincts
Rivalry, curiosity, sociability, shyness, hunting etc.
Problem with instinct concept
How many are there?
Descriptive not explanatory
What is and is not an instinct
Vague and arbitrary
Circular reasoning (Holt): everything you do can be called an instinct.
e.g. Thumb twiddling instinct AND thumb-not-twiddling instinct
Ethology (study of behaviour biologically)
Behaviourists believe we are born as a blank slate and everything is learnt
Study of behaviour in a natural setting
Identify action patterns of species and causes of action patterns
Evolution, development, function of behaviour
Instinctive behaviours exist because they have or had adaptive value for the species
Behaviour as viewed by ethology
Certain mechanisms to help break down instinct:
- Action specific energy: in the perceiving animal
- Key stimuli: releaser, sign stimulus (environment)
- Innate releasing mechanism: brain mechanism that detects key stimulus
- Fixed action pattern
Instinctive behaviour sequence that is indivisible and
runs to completion
- E.g. Kelp Gull chicks peck at red spot (key stimulus) on mother’s beak to stimulate regurgitating reflex
Key Stimuli and Innate Releasing Mechanisms
These are all adaptive behaviours
May even be socially adaptive behaviours in humans
Example: Monkeys and recognition of facial expressions
- Chimpanzees can recognise facial expressions in humans
Another key stimulus can be a baby face: key features of a baby’s face that makes it something you want to take care of include big eyes, small noses etc.
- This idea was picked up by Disney etc. for their cartoon characters that don’t want to be harmed look like babies vs the evil characters
