19. Drive States Flashcards
An affective experience (something you feel, like the sensation of being tired or hungry) that motivates organisms to fulfill goals that are generally beneficial to their survival and reproduction
Drive State
Examples of drive states
hunger, thirst, sexual arousal, tiredness
Has a profound impact on the fucntioning of the mind. It affects psychological processes, such as perception, attention, emotion, and motivation, and influences the behaviors that these processes generate
Hunger
What state possess valence (positive or negative) and serve to motivate approach or avoidance behaviors
Affective state
Are unique in that they generate behaviors that result in specific benefits for the body
Drive state
The tendency of an organism to maintain stability across all the different physiological systems in the body
Homeostasis
What are the two key factors that maintain homeostasis
1.) Set point - State of system being regulated must be monitored and compared to an ideal level
2.) There need to be mechanism for moving the system back to this set point - to restore homeostasis when deviations from it are detected
Examples of homeostatic mechanisms
Blood circulation, immune responses
(automatic, nonconscious)
Most drive states motivate action to restore homeostasis using __ and __
punishments, rewards
When you behave poorly by departing from the set point, you experience bad feelings
Punishments
When you behave well, you experience pleasure that comes from any activity that moves the system back toward the set point
Rewards
As __ intensify, they direct attentio toward elements, activities, and forms of consumption that satisfy the biological needs associated with it
Drive State
Outcomes and objects that are not related to satisfying a __ lose their value
Drive State
Drive state produce a second form of attention-narrowing: a collapsing of time-perspective toward the present
Impatience
Third form of attention-narrowing involves __
Thoughts and outcomes related to the self versus others
Three forms of narrowing of attention
Loss of value, impatience,desire to do good for others
Classic example of a drive state
Hunger
Generally triggered by low glucose levels in the blood, and behavior resulting from this aim to restore homeostasis regarding those glucose levels
HUNGER
External cues that cause hunger
time of day, estimated time until next feeding, sight, smell, taste, touch
T/F
Hunger has nuances that can provoke the eating of specific foods that correct for nutritional imbalances
True
ex. craving eyes of fish = rich in vitamin c, body craves it
Located in the lower, central part of the brain that plays a very important role in eating behavior
Hypothalamus
Responsible for synthesizing and secreting various hormones, concerned largely with hunger
Hypothalamus
Damage in these region can eliminate the desire for eating entirely
Lateral Hypothalamus
Activation of this area can not only increase the desirablility of food but can also reduce the desirability of non-food related items
Lateral Hypothalamus
