Q

Role of prefrontal cortex

Q

What is the behavioural activation system

A

The behavioral activation system is activated within a person when they receive a signal from their environment or situation that something positive can be attained if they perform that activity.

25
Bas system is activated where?
The active left prefrontal cortex for people who have left dominant PFC
26
Behavioural inhibition system (BIS)
A system that predicts an individual's response to anxiety-relevant cues in a given environment. Activated in times of punishment, neglect or boredom.
27
Role of orbitofrontal cortex
Stores and processes reward-related information that formulate their preferences and make choices between options.
28
Where is the orbitofrontal cortex?
lies beneath the prefrontal cortex
29
role of the anterior cingulate cortex
Attention, monitoring conflict, making choices, predicting consequences, and alerting other brain areas
30
What is the stress hormone?
cortisol
31
when is cortisol activated?
during stressful situations
32
short-term but long-term associations with cortisol
short- has an adaptive function long-term- poor intellectual functioning, negative affect, poor health concerns
33
Cortisol is produced by blank acess
HPA
34
Oxytocin is known as blank. Role?
Known as the bonding hormone, supports the tend and befriend stress hormone, and raises trust in others.
35
Oxytocin motivates what
seeking counsel, support, and care of others during stress
36
Testosterone: associated with what traits
high competition, status-seeking and sexual motivation
37
Testosterone underlies what behaviour. Underlies what effort
underlies status-seeking behaviour Underlies the mating effort
38
What is a need?
Any condition within the person that is essential and necessary for life, growth, and well-being
39
When needs are nurtured and satisfied what occurs
growth occurs, life is maintained, and well being is enhanced
40
41
If needs are neglected or thr
damage occurs that disrupts biological or psychological well being
42
Three types of needs
1. psychological needs 2. physiological needs 3. implicit motives
43
Physiological needs
Biological condition within the organism that synchronizes brain structures, hormones, and major organs that regulate bodily well-being
44
psychological needs
Inherent psychological process underlying the proactive desire to seek out interactions that promote personal growth, social dev, and psychological well-being
45
implicit motives
internalized or learned from our emotional and socialization histories
46
Model of the need drive behaviour sequence
1. satiated state -> physiological deprivation develops -> prolonged physiological deprivation produces bodily needs -> need intensifies -> goal directed behaviour to attempt to gratify drive -> gratifying behaviour -> drive is reduced -> system occurs again
47
Describe the 1st steps of the model.
Physiological need describe a deficient biological condition
48
describe step 2 Drive
conscious manifestation of an underlying unconscious physiological need
49
step 3 homeostasis
bodies tendency to maintain an internal stable state
50
4. negative feedback
the phonological "stop system" for homeostasis
51
5 input and output
input:input= means of activation, output= different goal directed behaviour
52
intraorganismic mechanisms
include all the biological regulatory systems that activate, maintain, and terminate a need. include brain structures
53
extra-organismic mechanisms
Include all the environmental. influences that activate, maintain and terminate a psychological drive
54
3 important psychological needs
thirst, hunger, sex
55
describe thirst
consciously experienced motivation state to cause the need to replenish the water deficit
56
hunger
involves a regulatory system of both short-term regulation and long-term energy balance
57
sex
sexual motivation rises and falls in response to a host of factors, including hormones, external stimulation and cues, cognitive scripts
58
thirst involves what processes
physiological regulation, thirst activation, thirst satiety, hypothalamus and kidneys and environmental influences
59
When does this occur bodily?
when there is a deficit in body fluid between the intracellular and extracellular fluid
60
the important role of kidneys and hypothalamus
hypo detects little water and sends message to the kidneys, kidneys maintain water making pee more concentrated
61
glucostastic hypothesis for hunger:
increase/decrease in glucose signals to increase or decrease eating
62
lipostatic hypothesis
Fat tissue secretes ghrelin when hungry and leptin when full
63
Can we determine our set weight point?
no, it has a range
64
set point theory?
everyone has a genetically pre-determined body weight or set point, which is resistant to change
65
traditional sex response
desire-> arousal-> orgasms-> resolution
66
alternative sex response
inteimacy needs-> being open and responsive to sexual stimuli-> arousal-> desire-> enhanced intamacy
67
Sex model 5 steps
intimacy needs-> sexual stimuli-> sexual arousal-> sexual desire to continue-> enhanced intimacy
68
evolutionary basis for sex
men and women have evolved distinct psychological mechanisms that underlie their sexual motivations and mating strategies
69
what men want
young attractive mates
70
what women want
powerful high status mates
