Humans- 83.4% correct in one try
Machine- 10.3% correct in one try
Perspectives on the mind - Answers -Behavior --> The mind
Brain -->The Mind
Behavior - Answers --Main focus of cognitive psychology
-Expression of the mind
Brain - Answers --Main focus of cognitive neuroscience
-Physical basis of the mind
History of cognitive psychology - Answers --Physics begain in the 1600 with Galilei and
newton in the 1600s
-Modern Chemistry began in the 1700 with Boyle and Lavoiser
-Beginning of cognitive psychology is somewhere in the 1800s.
-It is a young field because no one knew where to begin
Early work - Answers -innovations and debate on whether and how to even measure
mental processes
Introspection - Answers -1st attempt to measure the mind.
-It is a way of measuring the mind.
Wilhelm Wundt (1832-1920) - Answers -Analytic introspection
-Systematic
-Highly trained observers
Periodic Table of the Mind - Answers -Finds the basic sensations (atoms) from which
experiences are built
, William James (1842- 1910) - Answers -Based on his own insights on introspection
-His method of introspection was to use himself. It was how he thought of thing; he was
the experimental subject.
-Deep thinker; not systematic
Problems with introspection - Answers --Hard to get reproducible results
-Variability
-List of basic sensations did not agree
-Not objective <-- Psychology struggles with objectivity
Common Characteristics (early more objective approaches) - Answers -They link a
mental process to a physical ( measurable) property
Franciscus Donders (1818-1889) - Answers -How long (physical property) does it take
to make a decision (mental process)
1st Condition Ex. "Whether a spot is on the left or the right"
2nd condition ex. "Dot on the left, knock"
Donders Reasoning - Answers --Response time to be minus response time to a: how
long it takes to make this decision
-We are discussing this because he is an early researcher aiming to objectively
measure mental processes.
Hermann Ebbinghaus (1815-1909) - Answers -How fast do memories fade?
- He measured how long it took to memorize all sequences in a list...then waited a
while...Then measured how long it took to re-learn them.
-used himself as an experiment subject
-We are discussing him because he is an early researcher aiming to objectively
measure mental processes
-Physical= change in savings over time
-mental= memory
Ernest Weber (1795-1878)
Gustav Fechner (1801-1887) - Answers -Quantifying perception
-Said the larger the quantity (e.g weight, size), the larger the change in that quantity
needs to be to be noticed
-Mental= Perception
-Physical= Quantity (length
