MOTIVATION
moment to moment urge to behave in 1 certain way versus another
DRIVE
basic/instinctive need
HOMEOSTATIC THEORY
Motivation:
behaviors of an organism that are performed maintain constancy of the internal environment
KONRAD LORENZ
1. ex used
2. 3 things it discovered
3. Model used
1. egg rolling in geese
2. - behavior is a fixed action pattern
- activated by a releaser
- guided by underlying motivational state
3. Psychohydrolic Model
NIKO TINBERGEN'S HIERARCHICAL MODEL
1. Neurobiological?
2. Describe
1. No
2. Releaser opens gate allowing nrg to flow down many diff paths affected by neurtral stimuli
- releaser can open the gate
- when gate closed, nrg will jump to different activity, aka displacement behavior
- nrgs must flow somewhere
DON PFAFF'S MODEL
1. Basically, what does this model show?
1. every behavior has a neuronal basis
NEURAL BASIS OF GENERALIZED DRIVE OR STATE OF AROUSAL
- What brain regions are involved (4)?
1. RAS
2. Locus coeruleus (pons)-noradrenergic
3. Raphe Nuc. (brainstem)- 5HT
4. Midbrain- DA (i.e. substantia nigra)
ZUGUNRUBE
1. Defn.
2. When observing vector analysis of normal NNE migration, what does it demonstrate
3. How was this demonstrated?
4. What happens when shown Planetarium sky?
5. What happens when planeterium sky shifted so N star is at true south?
6. What happens when planetarium has diffuse illumination?
7.
1. Nocturnal restlessness in wild songbird
2. Zugunrube is directional, vectors run in NNE directions
3. Emlen cone: bird in cone shaped apparatus w/ opaque screen above w/ wire screen top, ink pad
4. NNE vectors
5. SSW vectors
6. diffuse vectors in all directions
