Question 1

why is electrode on the cheek

Answer 1

eyes are basically magnets –> changing electrical fields –> messing with EEG

Question 2

Different types of waves

Answer 2

delta <4 hz = slow wave sleep/babies
theta 4-8 = meditation
alpha 10hz = relaxed state
beta 14-30 = movement in motor cortex & thinking
gamma >30 = coordination between neurons

Question 3

EEG analysis pipeline

Answer 3

frequency filter
deal with eye and heart artefacts
cut epochs around event markers
apply baseline correction
group epochs
acverage epochs to get ERPs
compare ERPS
stat analysis

Question 4

ERP

Answer 4

event related potential, the average of a group of epochs

Question 5

P300

Answer 5

effect found when seeing the playing card you were instructed to remember

Question 6

pyramidal neurons

Answer 6

organised in columns along the curvature of the brain, its their activity that is picked up by EEG

Question 7

priming experiments

Answer 7

stimuli are similar in one way and you start probing how similar the brain thinks they are

Question 8

n150

Answer 8

basic visual processing

Question 9

n250

Answer 9

orthographic overlap / reconciliation of visual difference

Question 10

p325

Answer 10

checking whether word is part of lexicon or not

Question 11

ventral processing stream

Answer 11

visual stimuli are processed from the dorsal to the ventral side of the brain

Question 12

Foreign language effect

Answer 12

reduced emotional resonance in second language, processed less automatically

Question 13

construction integration model by kintsch

Answer 13

different levels of integration: surface, representation, situation model

Question 14

simple view of reading:

Answer 14

text decoding + language comprehension = text comprehension

Question 15

research on comprehension outcomes after reading:

Answer 15

lower grades: listening > reading
higher grades: listening < reading

Question 16

results think aloud study by PHD student

Answer 16

no effect of modality on average number of responses, comprehension processes were comparable

Question 17

Speech act literalism

Answer 17

there is a link between sentence types and speech act types

Question 18

research on whether linguistic information is enough

Answer 18

images help in comprehending when looking at single words

Question 19

results from last lecture

Answer 19

-we use mental simulations to comprehend language
- we simulate objects, their shape, orientation & colour
