- Behavior
- Innate
- Genetically Determined
- No sense of purpose
- escape reflexes in response to stimulus
- Kinesis non-directional, rate of movement increases in unfavourable condiitons
- Taxis iis directional behavioural response to stimulus
- Complex innate behaviours: series of innate behaviours Eg waggle dance
- Genetically Determined
- Learned
- Change and adapt with experience
- Habitiuation: ignoring due to no reward or punishment
- imprinting in sensitive period 36 hours. associating
- Classical conditioning: dog and salivia, Pavlovs dog, bell becomes a conditioned stimuls to saliva
- operant condiitoning: skinners box, associating something with a reward or punishment.
- exploratory learning: retaining information eg escape routes, food
- insight learning: the ability to solve problems and solution remembered
- Primate Behaviour
- Heirarchy is order of importance Eg rights to mate and food
- mountain gorillas: one dominant male, protect and find food. social organisation and primate behaviour
- socail behaviours include grooming and caring for offspring
- advantages: birth to few infants, 1 to 1 care increases survival rates.
- young learn through observation
- Dopamine and DNA
- low levels dopamine = parkinsons. Dopamine pre-cursor l-dopa is treatment.
- raised levels of dompamine linked with gambling and schizophrenia
- dopamine increases arousal, decreases inhibition, increase in creativity
- activities affected by variants in the receptors DRD1-DRD5
- 50 variants of DRD4 gene. inheritance of a different variant affects levels of dopamine in brain.
- EG particular variant is frequent in ADHD sufferes
- low levels dopamine = parkinsons. Dopamine pre-cursor l-dopa is treatment.
- Innate
