Q

Two main types of Statistics

A

Descriptive - organize and sumerize (measure - central tendency, variablity, correlation )

Inferential - laws of probability to generalizability of findings (NHSignifcanceTest, alternative hypoth, statistically signifcant)

Q

Central Tendancy m m m

A

Mean - avearage of all
Median - the score that falls exaclty in the middle of the distribution score
Mode - the most frequent score.

Q

Standard Deviation (variablity)

A

Bigger the value the bigger away the spred of values ( the average the difference in values… or the dispertion away from it’s average (not covariance).

Covariance is how they move together

Q

Correlation / Correlation Coefficient tells us

A

Tells us strength of relationship and direction (+/-)
0 means no relationship / 1 is total

positive and negative corelation

Q

corelation ≠ causation

A

Corelation can tell what varriables are related by not how. Corelations doens’t tell us causation.

Q

Psychology theory:

A

a system of interrelated ideas (must be testable) that is used to explain a set of observations

to move from description to understanding

1.a theory must be testable,

2.theory develops a hyplotheisis to research and test.

3.hypothesis is a tentative statement about relationship between varriables.

Q

Operation definitions

A

a description of the action used to measure or control a variable
(how are we defining, how are we measuring)

Q

Indepent / dependent variable

A

investigate manipulates IND variable, observes changes in second DEP variable (only method where we can make cause and effect conclusion)

ind varies - dep affected

Q

Extraneous variables

A

extra variables or 3rd variable that could effect dependent variable.

3rd value like foot size

This can lead to a confounding of varriables where it’s difficult to make out effects

Q

Descriptive / Correlational research

A

descipriction of behaviour / identify assocaitions between varriables

when we can’t get ethics clearance or don’t interfere with participents

Q

Descriptive Corelate - Naturalistic Observations

A

Advantages- more realistic, helpful if little is know
Disadvantages - reactivity of subjects, coverting obs into numbers

Q

Descriptive Corelate - Case study

A

indepth invest of individual or group

HM

Advantage - provide detail insight
Disavantage - easily influenced by researcher confirmation bias

Q

descriptive corelate - Survey

A

Survey/questionare most popular

advantages- easy/inexpensive, data on hard to observer behaviour, large samples
disadvantages- selfreport is unreliable, can’t draw causal conclusions(same with most desc/core, can’t trust peoples opions of themselves.

24
Q

descriptive/correlate - advant/disadvant

A

advant - examine topics you coudlnt’ using experiments, broadens schope of psychology

disadvant- can manipulate variables like in experiments, can’t determin causality

25
Willhem Wundt
Liepzig , first lab, first pubs - believed psychology should examine consciousness and the awareness of the immediate experience **Focus on the mind**
26
Structuralists vs Functionalist
S - Edward Bradford Titchener ( **basic** elements or structures of psych experience. sensation, images, feelings **HOW WE FEEL**. Highly trained INTROSPECTIONISTS... Os.Kulpe points out imagelss thought F - William James (why we feel, was is the adaptive **PURPOSE** of consciouness, aka why we forget. influceed Dawing Orgin of Special, says structualist are missing the nature of consciousness. STREAM OF CONSIOUSNESS
27
Fuctionalism turns into Behaviourism
John b Watson. Only wanted objectivite. claims should be verified or disproved. Strick scientific method. Response - Stimuli
28
Freud
influenced by medical backgound. psychoanalysis not scientifically rigourous. SLOWed scientific progressed? Claim that thought and processing occured outside of awareness and influenced behavior proved to be true (AWARNESS)
29
Behaviourism and Skinner
we can't deny things happen in the black box but we can't prove it must be observable / eviromental factors determin behaviour (not inate) **BEYOND FREEDOM AND DIGNITY** free will is an illusion, significant contrib to psychology reversed the impact of freud psychoanalytic theory but linguistics stay to simplisitc.
30
Humanism
felt psychoanalytic theory and behaviourism was de-humanizing Abraham Maslow and Carl Rogers optomistic views of humanity- to understand behaviour we need to understand peoples need to evolve and fulfill their potential. lack of coheision was an issue but Person centre therapy
31
Person Centred Therapy
1 unconditional positive regard 2. extend empathy 3. transparency don't try to be the sole expert in theraputic relationship
32
Cognitiver Revoloution and Neuroscience
disillusioned with BeHave neglect of mental processes in cognition.... reward and punishment not enough doesn't explain interpretation. poverty of stimulus
33
James Oldes
found reward system in the mesocortical limbic circuit of brain, implanted stimulating electors in animal brains
34
Wilder Penfield (Montreal procedure) for epilepsy
Proved there are specific regions for specific functions (memories and thoughts)
35
Donald HEBB
father of Neuropsychology develops specific new tests(head injureis) **Organization of behavior** Fire together, wire togehter We finally see inside the black box
36
Culture and Diversity
Focused on Western Cultures
36
Evolutionary Psychology
starts in 1980s. examines behaviours processes in tersm of their adaptive value of passing on genes Similar to functionalism
37
Positive Pschology - APA
Martin Seligman after WWII pschology turns from research to clinical and gets to rigidity. Wants to investigate happiness and creative and fulfilling aspects of human existence. (3 good things task)
38
definitnion of Psychology
Greek psyche = soul logos - the sutdy of 16th centrey study of the soul, spirit, mind 17 study of mind Two main distinctions CLINICLAL and RESEARCH
39
empirical method makes p an S
psychology a scientifc endeavour with objective evidence based on fact
40
Goals of scientific enterprise
1. measurement and description 2. understanding and prediction 3. application and control advantage of scientific approach 1. clarity and precision 2. intolerance for error
41
operational definition describes
the actions or operations that will be used to measure or control a variable
42
orientation procedures
eg. anxiety from being told you're going to be shocked to evoke anxiety
43
Random assignment and sampling
samping is pulled after the face
44
Within subjects / Between subjects
comparison made within groups or between groups
45
Generalizability
researcher may sacrifice some control for greater generalizability
46
Naturalistic observation
careful observation without intervening directly with the participants. naturalistic allows researchers to study behviour under conditions that are less artifical , but reactivity can occur
47
corealation/causation
no way to pove correlated variables are causually related. corealation occurs when two variables are related to each other
48
Statistics
math used to interpret numerical data
49
Normal distribution
symmetrical bell shaped curve
50
the importance of replication
repetition of a study to prove that the results are duplicated
51
Self Reporting and social disrerablity
People can't be trusted in surveys
52
Double Blind
Where the experimenters don't know what group the participants are in.
53
Theory Vs Hypothesis
Theory has an explanation a hypothesis does not
54
postitive and negative correlation
positive - variables move together. negative variables move a part mortgage/interst(neg) vs study/grades(pos)
