Ch. 12 - Emotional and Motivated Behaviour (FINAL) Flashcards
emotions
cognitive interpretations of experience
anatomy involved: hypothalamus, limbic system, frontal lobe
motivated behaviour
purposeful and goal directed
we do things that are rewarding; it is not free will that motivates us
innate and learned behaviour
IRMS (innate releasing mechanism)
- prewired in brain, genetic
environmental learning
- SKINNER
- associated learning is classical conditioning
- positive and negative reinforcers strengthen behavioural responses
preparedness
likelihood to respond to certain stimuli over others
neuroanatomy of behaviour: hypothalamus
contains pit gland(s):
- anterior (produces hormones)
- posterior (distributes hormones)
feedback loop
1. hypothalamus
2. ant. pit.
3. target organs
4. a) back to hypothalamus
4. b) hormones
neuroanatomy: medial forebrain bundle (tract and purpose)
tract that connects HYPOTHALAMUS to BRAINSTEM
involves DOPAMINE
stems from the VTA
controls both pathological (impulse and addiction) and motivated (sex, eating, mesolimbic pathway) behaviour
regulatory and non-regulatory behaviour
regulatory: survival needs and homeostatic mechanisms
non-regulatory: unnecessary behaviour
limbic system: parts (4)
hippocampus, amygdala, prefrontal cortex and basal ganglia
limbic system: control of emotions (3 types)
autonomic response: visceral reaction, homeostatic action - hypothalamus
subjective feelings: anger, fear, love - amygdala and frontal lobes
cognitions: thoughts about experiences, prefrontal cortex
limbic system: amygdala and a specific syndrome
involved in all emotional responses especially fear and anxiety
closely related with frontal lobe functioning
Klüver-Bucy syndrome:
- visual agnosia ad hypersexuality in patients with amygdala removal
prefrontal cortex: professionals
Moniz Freeman: transorbital leukotomy, UNETHICAL
Carlyle Jacobsen: relaxation of chimps with lobotomies
prefrontal cortex: anatomy (5 areas)
orbitoprefrontal cortex: impulse inhibition
dorsolateral PFC: planning/working memory
premotor cortex
motor cortex
ventromedial cortex: value assessment
the reward system - 3 components
affective: pleasure experienced
learning: where you can access reward
motivation: desire/cravings
reward system: want vs. like
want: dopamine, subconscious, striatum/PFC
like: opioid/endocannabinoid, conscious, the “hedonic hotspots”
