After Midterm Flashcards by Haley Lam

Walk through what happens when a scary stimulus pops out, leading to emotion. (3 steps)

What is the conclusion? What does our emotional experience depend on?

1) Sensory areas receive stimuli
2) Sends signals to rest of the brain
3) The rest of the brain allows us to consciously think of the event and cause unconscious physical changes

Conclusion: Our emotional experience depends on both conscious and unconscious bodily responses.

2) Valence

What part of brain is activated during regret after a choice with bad outcome?

Valuation circuit OFC

What is 'regret'?

When the value of a behavior's consequence does not correspond to value judgement. A conscious subjective interpretation

What brain regions are more or less active in emotion labelling?

Right vlPFC (more activity) Amygdala (less activity)

Correlation between vlPFC and Amygdala activity

Negative (r= -.5)

What brain region(s) predict both vlPFC and Amygdala activity?

vmPFC/ACC

vlPFC is important for this EF. How does this relate to emootions?

inhibitory control regulates negative emotions

How is conscious perception of a negative emotion related to amygdala activity of it?

Consciously perceiving (by producing speech) negative emotion regulates amygdala response. Talking about it regulates our responses to them.

Paul Ekman "Lie to Me" research

There exists basic emotions that are universal. Asked Fori tribe to 1) make face and 2) label expression Expressed and Recognized same as western

Basic emotions

Anger Disgust Fear Happiness Sadness Surprise

4 elements of basic emotions

Evolutionary Unique Instinctive (unconscious) Universal

Blind vs. Non-blind atheletes and emotion. How does this relate to basic emotion theory?

We have evolutionary ways to express emotion. blind and non-blind athletes have same expressions when celebrate/lost respectively.

What are complex emotions?

Combinations of basic emotions. Long-lasting feelings that are evolved.

What major brain region did we study is heavily involved in EFs? What is included?

Prefrontal Cortex (PFC) Everything that isn't M1

where is the FEFs?

PreMotor Cortex

Where is IFG?

Inferior Frontal Gyrus In vlPFC and a bit of FPC and dlPFC and PrM

What regions activate for Go/No-Go? What type of EF?

Inhibitory Control Right vlPFC

What regions activate for n-back task? What type of EF? What specific task of each?

Cognitive Flexibility Bilaterally, dlPFC vlPFC ACC: error detection, conflict monitor, task shift

What is valuation circuit?

OFC and FPC and vmPFC

What is the purpose of valuation circuit?

Assess reward of stimuli

What is part of EF circuit?

ACC and dlPFC

Which area holds mental representations?

vlPFC

Two types of language skills

Receptive Language Skills Expressive Language Skills

4 units of language

Phonemes: basic sounds Morphemes: basic units of meaning Syntax: grammar rules Semantics: high-level literal meaning

What are connectionist models of language?

They involve nodes and weighted connections between nodes to show how we mentally represent language

What parts of the connectionist model tends to change over time?

the lexical-semantic changes, getting stronger and stronger. lexical to phonological doesn't change much

Semantic network

Lexical nodes connections with each other (based on meaning/semantic feature)

Phonological network

Connections based on how things sound (phonology)

co-occurance network

What usually follows (eg. autocorrect)

What are weighted connections?

The relationship between semantics/lexical nodes/phonemes in connectionist model

3 types of weighted connection networks

phonological semantic co-occurance

What are speech pipelines?

Order of how we produce or comprehend language

Speech Processing Pipeline

Phonemes --> Lexical nodes --> Semantic Features

Speech Production Pipeline

Semantics --> Lexical Nodes --> Phonemes

Errors in speech processing pipeline? Errors in speech production pipeline?

Might hear a wrong but similar-sounding word (error in predicting what we hear) Might say a wrong but similar-sounding word (error in predicting what to say next)

Which part of Baddeley's model is related to speech/comprehension?

Phonological loop. And based on central executive's goals

When phonological information in Working Memory decays too fast, what error occurs?

Error in processing sounds into words.

When inhibitory control to inhibit phonologically similar words fail, what error occurs?

Error in finding meaning out of words.

When there is background noise, what EF is harder, and what happens in phonological network?

Inhibitory control is harder. More unrelated words will be active.

What word is most cognitively active?

The word that is currently spoken.

Saying "Ambulence" instead of "Firetruck" is a failure of what?

Inhibitory Control (semantic network)

Saying "car" instead of "cat" is a failure of what?

IC (co-occurace)

95% of right-handers; 70% of left-handers In left side of brain

For split-brain patients, when holding ball on left hand, what will they say? what will they draw?

Will say holding nothing. But can draw it with left hand.

Executive Function is same as what in another model?

Baddeley's Model. Central Executive.

3 Core Executive Functions

1) Inhibitory Control: 2) Working Memory 3) Cognitive Flexibility

Definition of inhibitory control

Ability to control thoughts, attention, emotion, override things to accomplish a goal despite lures.

"Habits of thoughts; some external stimuli."

Lure

Prepotent mental representations

Delayed gratifiction is related to what within inhibitory control?

Behavioral inhibiitoin

staying on task when music is on is a type of what function?

behavioral inhibition (inhibitory control)

behavioral inhibition is aka

self control

prepotent mental representations have to do with which part of IC?

cognitive inhibition

Working memory is intertwined with _____, especially _______ (subsection of first part)
