Q

What was Donders known for?

A

uses a chronometer (or a Hipp cronoscope)
Objectively measures reaction time up to 500Hz, then to 1,000Hz
Shocks participant’s feet individually and then asks them to report which foot was shocked.
IV - know which foot will be shocked or not
DV: reaction time
Finding: knowing which food increased RT by 66ms.
Choice RT-Simple RT= time to make a decision
Not a direct observation of mental processes
But an inference abt what’s happening.
The choice reaction time task added decisions by requiring participants to 1st decide whether the left or right light was illuminated and then which button to push.

Q

Why was Donders’ experiment important info for us?

A

It combines a behavioral study with a simple computational model of cognitive processes
Mental chronometry is still used even today (a lot)
Unfortunately, this method can be conflated with other simultaneous processes.
It was the 1st cognitive psychology experiment and bc it illustrates something extremely significant abt studying the mind; mind responses cannot be measured directly, but have to be inferred from behavior.
He didn’t directly measure their mind, he just measured how long they took from the reaction times

Q

What was Ebbinghaus known for?

A

He was focused on memory and forgetting. Specifically, how quickly info that is learned is lost over time.
He used himself as a participant for his experiments.
Learning Phase
List of trigrams
CEP, TUL, FOM, WAZ
Considered learned when the list is recalled twice without error.
Relearning Phase
After some time, same learning procedure
Savings Score: Time of learning - Time of relearning = Savings score
Savings scores are specifically sensitive
Measures learning and forgetting
Reduction in savings provides a measure of forgetting, with smaller savings means more forgetting

Q

Def: savings curve

A

shows that memory drops rapidly for the first 2 days after the initial learning & then levels off.
This is important bc it demonstrated that memory could be quantified and that functions like the savings curve can be used to describe properties of the mind.

Q

What was James known for?

A

Viewed functionalism as a means of identifying psychological constructs
Rather than individual units, looked at:
Cause and effect
Prediction and control
His observations were based not on the results of experiments but instead on the observations abt the operation of his very own mind.
He focused on the nature of attention.
Cognitive topics he considered included: thinking, consciousness, attention, memory, perception, imagination, & reasoning.

Q

What was Watson the Asshole known for?

A

Eliminates the mind as a topic
Why not just study behavior? Since our behavior is caused by our thoughts.
Instead, he focused on directly observable behavior
But the drawbacks of his method was:
It produced extremely variable results from person to person.
These results were difficult to verify bc they were interpreted in terms of invisible inner mental processes.
Benefits: evidence-based research
Contributes to theories of learning/associations
Ignores “intervening” variables
Stimuli -> ?? -> behavior

Q

Explain the Watson & Rayner experiment

A

Study of classical conditioning
Demonstrates that behavior can be analyzed without mentioning the mind
Stimuli -> behavior/conditional response
“Little Albert”
Watson and Rayner subjected Albert (9mon boy) to a loud noise every time a rat came close to the kid.
After a few pairings of the noise with the rat. Albert reacted to the rat by crawling away as quickly as possible.
Pair neutral stimulus with a natural event that produces a response.
White rat (NS) paired with a loud noise (UCS)
White rat + loud noise = scared which turns into: white rat = scared
NS becomes conditioned to produce a response
