Approaches 1 Flashcards
What are the origins of psych?
Roots in 17th and 18th century philosophy
Rene descartes and his Cartesian dualism (mind and body are separate) was stating point
Locke and concept of empiricism (sensory info studied scientifically)
Charles Darwin and evolution
Who is Wilhelm Wundt?
Father of psychology
1873 published 1st psychology book
Contributed to psych as a science
1879 opened first psych lab in Germany
What is introspection?
Mental processes can be studies systematically as they occurred
Eg participants shown object like metronome and asked to describe their inner processes
Stimulus is always the same and controlled
Criticisms of introspection
not reliable- unobservable
researchers observed diff things
other psychologists already produced theories you can easily generalise
unreliable- participants unaware of factors influencing them
how did psych emerge as a science?
watson criticized it as was subjective so behaviourism and scientific science came about
what is empiricism?
all knowledge comes from observation and experience alone
assumptions of scientific approach
behavior is seen as being caused (assumption of determinism)
if behavior is determined, should be able to predict it in diff conditions (assumption of predictability)
What is the scientific method?
the use of investigative methods that are objective, systematic and replicable
dont let preconceived ideas influence
replicable and reliable
measurement of empirical data carried out accurately with consideration of other factors
+ and - of scientific method
+
relies on objective and systematic methods
rely on belief in determinism so can establish causes through replicable methods
scientific theories dont fit facts anymore, can be refined /abandoned
-
objective and controlled so not very ecologically valid
lots of subject matter is unobservable so lack accuracy
not all psychologists think behaviorism can be studied scientifically
Basic features of psych as a science
controlled, experimental conditions show cause and effect and test hypotheses
highly standardized- reliable
use of iv and dv
objective, systematic, replicable
build and refine and falsify theories
what is behaviorism?
believes psych is study of behavior not mind
scientific as can study directly
all behavior is learnt through conditioning
what is classical conditioning?who came up with it?
learning through association
pavlov started idea then developed by john watson
Describe the study on classical conditioning- dogs
1902 pavlov’s dogs
dogs taught to associate bell with food so began to salivate
Ucs- object or event that produces reflexive action
ucr- response to ucs
ns- neutral stimulus doesnt produce response
cs- ns associated with ucs
cr- response to cs
describe the study on classical conditioning- little albert
Watson and Rayner 1920 induced fear of white rats in little albert
before: ns is rat, ucs is bang, ucr is cry
during: ns+ucs=ucr
after: cs=cr
+ and - of little albert study of classical conditioning
+
practical applications- devise treatment to maladaptive behavior
reliable- highly controlled
-
ethics- albert couldn’t consent or withdraw
generalizability- small sample
ecological validity- too controlled
what is operant conditioning?who came up with/ dveloped it?
behaviour is shaped through reinforcement
developed by BF Skinner but based on Thorndike’s laws of effect
positive reinforcement
strengthens behaviour (more likely to repeat) by providing rewarding consequence
skinner showed this by placing rat in skinner box with lever, rats bumped into it and food dropped. rats learned to go straight to lever
