Metacognition Flashcards
What is meta cognition:
Assessment and beliefs about our own memory and cognition
>often we overestimate how well we know something: overconfidence
Judgement of learning:
rank of how confident you will be able to remember/recall information
calibration:
Estimated v’s actual performance
good calibration=the numbers match the means JOL=% recall
resolution:
how well do our estimates predict actual memory performance
>measured by the correlation between judgement and recall
Immediate judgement
Asked immediately after to recall information
delayed judgement:
wait a period of time and then ask them to recall information
>need to retrieve it from LTM
>performance is much more accurate>good for accurate judgments
>resolution much higher
Desirable difficulty:
encoding variability: more retrieval paths
interleave rather than block material
use tests to enhance learning
Testing effect
Roediger and Karpicke
pt’s studied material and then they were tested
conditions: study study study study (STM)
study study study test
study test test test (much higher retention interval after 1 week and forgot less)
Accuracy regulation
name the three types:
1-report option
2-grain size option
3-plurality
what is report option?
> withhold answers-accurate because people only report what theyre confident about
helps on exams-MCQ mean there is a choice and they do have some knowledge there
helps on formula scored
grain size option:
How specific an answer is
if you widen the interval around a single answer it means you can maintain accuracy even if you dont know the specific answer
Plurality option:
Provide several alternative answers instead of just one
they can be worth part marks
costs of accuracy regulation:
informativeness: they withhold too much and intervals are too wide
sometimes confidence isnt always a good predictor of accuracy
