What is the forgetting curve
We learn a lot at first and after a few days we forget memory if there is no retrieval
who is ebbinghaus
Created forgetting curve and time savings method . original time 1000- second time 700 = 300 savings or saved time. studied how rapidly forgetting occurs
what did donders use
measured mental processing simple reaction time vs choice reaction time.
The difference between simple and choice
simple you react to a stimuli. choice you had to choose between two stimuli and react. choice takes longer
Unconcious inference
word coined by herman von helmvotz we assume the most likely possibility. perception is indirectly influenced by inferences about current sensory input that make
use of the perceiver’s knowledge of the world and prior experience with similar input
mental chronometry
scientific study of processing speed or reaction time to a cognitive task
to infer the content, duration, and temporal sequencing of mental operations
Information systems
Input —> transform —–> output
Wundt and 2 introspection
1st person to create a psychology lab. 2 looking at your own mind and reflecting, people were trained no way to verify what was true
savings time
the amount of time one saves when studying a material after an initial first time, to the
Second time a higher number means more accuracy original time to learn list minus the second time
It took to learn list of words ex is 1000 seconds first time - 600 seconds second time = 400 seconds saved

Shepard & Metzler’s
Look at mental rotation and how long it took people to rotate an image in their head. Used 3d abstract figures the bigger the angle the more it took people to react. Can store info visually
