Midterm 3 Flashcards
What is an emotion?
Responses that vary in “goodness” to external stimuli and internal representations based on physiological reaction, begavioral response, and feeling
List 10 emotions defined by Izard
Joy Interest/excitement Surprise Sadness Anger Disgust Contempt Fear Shame Guilt
Describe the James-Lange theory of emotion
Physiological arousal comes before emotion
ex: racing heartbeat followed by feeling of fear
Describe the and Cannon-Bard theory of emotion
Physiological arousal and emotion happen at the same time
ex: racing heartbeat as experiencing fear
Describe two-factor theory
Also known as Schachter-Singer Two-Factor Theory, postulates that emotions have 2 ingredients: physical arousal and cognitive appraisal
What is the low road and high rode theories?
Low road theory is the idea of feelings before thinking (emotional reactions seperate from cognitive appraisa)
High road theory is the idea of thinking before feelings (we appraise an event as harmless or dangerous before emotions arise)
Low is more reactionary than High road
Describe the lesion and deficits of patient S.M.
Bilateral amygdala atrophy due to genetic disorder
Unable to identify fear in faces and has a selective reduced experience of fear
Therefore unable to avoid dangerous situations
Where is the lesion located in the human patients with Kluver-Bucy syndrome? What are their symptoms?
Damage in anterior temporal lobe in monkeys
Damage in amygdala in humans
Symptoms: Docility, hyperroality, dietary changes, visual agnosia, amnesia, hypersexuality
How is the amygdala involved in implicit memory as well as explicit memory?
Implicit
critical for acquisition and expression of an implicitly conditioned fear response
Explicit
necessary for normal, indirect emotional responses to stimuli where emotional properties are learned explicitly
can enhance the strength of explicit memories for emotional events by modulating storage
How is the amygdala and the orbitofrontal cortex involved in decision-making?
OFC damage leads to trouble in anticipating consequences of their actions and learning from mistakes
What are all the emotional processes that the amygdala has been shown to be involved in?
Implicit emotional learning Explicit emotional learning Dicision making, attention, and perception Social interactions (eyes) Fear (possibly other emotions)
How is the insula involved in emotional processing?
Necessary to be aware of our body states (thirst, itch, sensual touch, etc.) to experience emotion
Which brain areas have been implicated in processing of anger?
Anterior cingulage cortex and the orbitofrontal cortex
Has a single brain area been identified to be invovled in all emotions?
No single area is responsible
What is receptive and expressive language?
Receptive: brain derives meaning from auditory speech or visual language input (also called comprehensive)
Expressive: brain produces spoken or written language output to communicate meamning (also called productive)
What is anomia?
Difficulty finding words
What is Dysarthia?
Difficulty controlling the muscles in speech
What is Apraxia?
Impairment of motor planning of speech articulation
What is Aphasia?
Deficit in language comprehension or production
Broca’s area has been associated with speech production. What new information do we have on this topic?
Broca’s area may not play a role in individual word production, but coordinates the transformation of information processing actross large-scale cortical netwroks invovled in spoken word production
Basically connects representations of words in temporal cortex to motor areas for articulation
Wernicke’s area has been associated with speech comprehension deficits. How has this view changed?
No clear association with lesions in Wernicke’s area and Wernicke’s aphasia, including surrounding tissue
What is the mental lexicon?
The collective store of information about the semantics, syntax, orthography, and the phonology of words
What is the mental correlate of the mental lexicon?
Supports the idea that mental lexicon contains semantic networks of related meanings clustered together that may involve the temporal lobe
What is cognitive control? Executive function?
Processes that allow information processing and behavior to vary adaptively from moment to moment depending on current goals
What is executive function?
Set of processes that have to do with managing oneself and one’s resources in order to achieve a goal
Give an example of decision making
choosing between two different things
Five an example of selective attention
Listening to one conversation while tuning out others
