Physiological Psych & Pharmacology 2 Flashcards
Areas in the left (dominant) hemisphere mediate what
Happiness and other positive emotions
Damage to the left (dominant) hemisphere produces a ___________ that involves depression, anxiety, fear, and paranoia
Catastrophic reaction
Areas in the right (nondominant hemisphere) mediate what
sadness and other negative emotions
Damage to the right (nondominant) hemisphere produces a _______ that involves inappropriate difference and/or euphoria
indifference reaction
This part of the limbic system is responsible for recognizing fear in facial expressions, attaching emotions to memories, and evaluating incoming information to determine its emotional significant and then mediating the emotional reaction to it
Amygdala
This regulates the physical signs of emotions through its communication with the autonomic nervous system and pituitary gland.
hypothalamus
What are the stages is Selye’s General Adaptation Syndrome model of stress and what happens at each stage
- Alarm Reaction Stage (activity of sympathetic nervous system gives the body energy to respond to stressor with a fight or flight reaction)
- Resistance Stage (if stressor persists, cortisol continues to circulate to help body maintain energy level to cope with stressor)
- Exhaustion Stage (physiological processes begin to break down)
Why has Selye’s General Adaptation Syndrome model of stress been challenged
research shows that physiological, psychological, and behavioral responses to stress aren’t all the same but are affected by the type of stress, the person’s genetic makeup, and their previous experiences (allostatic load model re-conceptualizes this)
The Allostatic Load Model posits that what is the key organ of stress (that determines what’s threatening and stressful)
the brain
________ refers to processes that allow the body to achieve stability by adapting to change
Allostasis
________ refers to an extended allostatic state that is due to chronic stress or repeated episodes of acute stress that can produce wear and tear on the body and brain
allostatic load
_________ is when allostatic load continues for days, weeks, or longer and has adverse effects on a person’s physical and psychological health
allostatic overload
This theory or emotion proposes that experiences of emotion follows physiological arousal (a person sees a bear in the woods and their heart beats fast and breathing more shallow and that causes them to feel afraid)
James-Lange Theory
This theory of emotion proposes that the experience of emotion and physiological arousal occur together when an environmental stimulus causes the thalamus to send signals to the cerebral cortex and sympathetic nervous system. This theory views all emotions as having similar physiological arousal
Cannon-Bard Theory
What is the facial feedback hypothesis
related to James-Lange Theory and predicts that facial expressions are associated with specific emotions and when we make them, we feel those emotions (smiling makes us feel happy)
This theory of emotion proposes that experiences of emotion are a result of physiological arousal followed by an attribution (cognitive label). It proposes that physiological arousal for most emotions are the same, but the cognitive appraisal, which is based on the external cues makes the differences
Schachter and Singer 2 factor theory
The epinephrine studies in which subjects looked for external cues to explain their ambiguous physiological arousal provides evidence for what theory of emotion
Schachter and Singer 2 factor theory
Also led to a lot of studies about the misattribution of emotion
What is Zillman’s excitation transfer theory
Related to Schachter and Singer’s 2 factor theory, this theory explains that residual physiological arousal from an event can be transferred to and amplify the arousal of a subsequent and unrelated event
(exp: watching a violent film can make people more likely to be aggressive to a confederate they encounter later)
This theory of emotion proposes that emotional reactions are due to cognitive appraisals and therefore 2 people experiencing the same event can have 2 different emotional reactions to it; Also proposes that physiological responses follow appraisals
Lazarus’ Cognitive Appraisal Theory
Lazarus’ Cognitive Appraisal Theory differentiates between 3 types of appraisal. What are they?
- Primary Appraisal- evaluating an event to determine if it’s stressful and if so what kind of stress? Is it a threat? Harm? Loss? etc (this can be determined by beliefs, values, expectations, etc)
- Secondary Appraisal- if the event is stressful, identifying coping options and if they have the resources to manage stress
- Reappraisal- person continues to monitor the situation and if they need to make changes to primary or secondary appraisal
LeDoux’s 2 System Theory proposes that what 2 systems are involved in mediating fear
- Subcortical System (survival system; low road)- responds quickly and automatically to sensory info about threats with physiological and behavior responses. The amygdala is a big part of this system
- Cortical System (conscious emotional system; high road)- processes info from the sense, subcortical system, memory, and uses cognition to determine if a stimulus is threatening and requires a fear response. Involves sensory cortex and frontal cortex.
Schizophrenia is due to ______ levels of what neurotransmitter
high levels of Dopamine (of hyperactive dopamine receptors)
Low levels of Dopamine in the substantia nigra is linked to what disorder
Parkinson’s
Excessive levels of dopamine in the caudate nucleus is linked to what disorder
Tourette’s
What dopamine pathway is known as the “reward circuit” and plays a role in the reinforcing effects of cocaine, amphetamines, nicotine, alcohol, opiates, and other substances
Mesolimbic dopaminergic pathway
ends in the striatum (nucleus accumbens)
The mesocortical dopaminergic pathway is involved with
emotion, motivation, and executive cognitive functions
The nigrostriatal dopaminergic pathway is involved in
the production of purposeful movement
This neurotransmitter is involved with movement, personality, mood, and sleep
Dopamine
This neurotransmitter is involved in movement, arousal, attention, and memory
Acetylcholine (ACh)
Low levels of ACh in the entorhinal cortex and hippocampus is linked to what
early memory loss associated with Alzheimer’s
This neurotransmitter contributes to movement, emotions, learning, and memory
Glutamate
Cell damage and death is caused by excessive amounts of what neurotransmitter
Glutamate
“Glutamate-induced excitotoxicity”
Glutamate-induced excitotoxicity can cause what conditions
stroke, seizure, neurodegenerative disease including Huntington’s and Alzheimer’s
