Predicting Performance Flashcards
Relating Initial and Later achievement
how well does early learning achievement predict later stages of achievement?
- use correlations
- role of abilities at each of the stages
Correlating performance trials
correlate a score for a given practice period to final score
- you can say “trial 1 will tell us if you’ll do well on the last trial” with about 50% accuracy”
- the more you practice, the better you will get at predicting
Intertrial correlations
procedure involving correlating all practice trials with each other
-provides info about relationship between performances of any two trials
Remoteness effect
seen when looking at rows of the intertrial correlation matrix
-the correlation between two trials decreases as number of intervening trials increases
Adjacent-trials effect
seen when looking at diagonals of intertrial correlation matrix
- the correlation between two adjacent trials (right next to each other) increases as the number of trials increases
- as you continue along in practice, any two adjacent trial correlations will get higher and higher b/c you’re finally getting strategy that consistently works
practice as a process of simplification (what do intertrial correlations show?)
- Performance early in practice is a poor predictor of performance later in practice (proven by remoteness effect)
- Number of abilities used systematically decreases with practice, so that the task comes to depend on just a few abilities at the end of practice (proven with adjacent trials effects)
Ackerman’s Integrated Model
integrates the concept of Fitts and Posner’s stages of learning with view of abilities
- abilities needed to perform a skill change systematically throughout learning
- abilities in use depend on the stage of learning
Ackerman: correlating ability and performance in stage 1 of learning
Stage 1 = Cognitive stage
- general intellectual abilities (IQ; info processing) are most important
- higher intellectual ability will result in better performance in stage 1 of learning
Ackerman: correlating ability and performance in stage 2 of learning
Stage 2 = Associative stage
- perceptual speed abilities are most important
- how quickly can you pick out info in a visual scene; how quickly can you access memory
Ackerman: correlating ability and performance in stage 3 of learning
Stage 3 = Autonomous stage
-perceptual and motor abilities are most important
-
