    What was the voltage for last switch:
    Another word for Participants:

    Measured if authority figure could get people to comply to a demand to hurt another by using pressure.

    • 40 Diverse Male individuals ages 20- 50yo
    • 460 Volts
    • Confederate (fake participant)
  20. Variable must...
    have at least two levels.

    Ex: age, gender, time etc
  21. operational definition =
    a definition of the variable in terms of the operations or techniques the researcher uses to measure or manipulate it:
  22. Construct validity

    What are the indicators of construct validity?
    • Construct Validity =  the degree to which a measurement device accurately measures the theoretical construct it is designed
    • to measure

    aka: It is measuring what it says it is measuring

    Face Validity – (Just going with your gut feeling and the measure appears to measure what it is supposed to measure.)

    Content Validity – (Make sure to check how other people are defining what you are a about to define.)

    Criterion-Oriented Validity:
  23. Positive linear Relationship:
    Negative Linear Relationship:
    Curvilinear relationship:
    No Relationship:
    Positive linear Relationship: Both increase or both Decease

    Negative Linear Relationship:1 Inc. & 1 Dec or 1 Dec & 1 Inc

    Curvilinear relationship: Increase then becomes decrease

    No Relationship: None of the above.
  24. Pearson Correlation Coefficient
    Scale ranges from...
    • Measure how strongly two variables are related.
    • -1 --> +1
  25. Research is aimed at reducing.... by.....
    Random variability: (uncertainty abt relationships btwen variables)

    By:Identifying systems between relationships
  26. What are the two approaches to the study of relationships amongst variables?
    • ** Nonexp: allows us to observe covariation (aka correlation) between two variables but DOES NOT measure cause and effect

    Experimental: 1 Variab. Manipulated & 1 Not = then Measure to determine if causal relationship exists
  27. Which group receives the treatment and which group does not and is the comparison group?
    • Treatment = Experimental
    • No treatment = Control group
  28. Independent variable = Variable being manipulated
    Dependent Variable = Variable being measured

    Where is the IV & DV plotted on a graph?
    • Ex: Caffine vs Bloodpressure
    • IV = Caffine
    • DV = Blood Pressure

    • IV = X Axis
    • DV = Y Axis
  29. Validity = Truth / Accurate representation

    Three types of Validity
    Construct Validity
    Internal Validity
    External Validity
    1)  Construct validity = the degree to which a measurement device accurately measures the theoretical construct it is designed to measure.

    • 2)  Internal validity =
    • the certainty with which results of an experiment can be   attributed to the manipulation of the IV rather
    • than to some other, confounding variable

    • 3)  External validity = the degree to which the
    • results of an experiment may be generalized
    • to other populations and settings.

    Ex: Too small of a sample size can effect external validity (ask 5 ppl about tuition increase & generalize that to whole population)

    • Solution:
    • random sample and large enough to be representative for the whole population.
  30. Extraneous Variables
    Confounding Variables:
  31. Reliability =
    the degree to which a measure is consistent

    ex: scale example = a reliable scale/test does not show much variability (change)
  32. We can assess the sability of a measure using?
    Symbolized by:
    A correlation of 0 =
    When negative =
    • Pearson Correlation Coeficcient: -1  0 +1
    • r
    • 0 = Two variables not related
    • When negative = there is a negative linear relationship
  33. Methods of assessing reliability:(6)
    For measure to accepted as reliable it has to be at least 80%
    • Test-retest Reliability:
    • A reliability coefficient determined by the correlation between scores on a measure given at one time with scores on the same measure given at a later time
    • Alternate Forms Reliability
    • is sometimes used and involves administering 2 different forms of the same test (to the same people at two points in time)
    • Internal Consistency Reliability = Reliability
    • assessed with data collected at one point in time with multiple measures of a psychological construct
    • Split-Half Reliability
    • You could determine the correlation between the total score on ½ the measure with the total score on the other ½ of the measure
    • Cronbach’s Alpha
    • another indicator of internal consistency reliability. (Cronbach Alpha compares every single item to seeif it is measuring same thing.)
    • Inter-rater Reliability = An indicator of reliability that examines the agreement of observations made by 2 or more raters.
    •   e.g., Linda & Mike observe/record Billy’s
    • aggressive behavior on the playground

      -People make mistakes.  At least 2 raters. Interobserver Reliabilty ( IOA)
  34. Anecdotal Evidence:
    One person’s experience / story
  35. Illusory Correlation:
    Belief of a relationship when one does not exist. OR belief in astronger relation THAN does exist.
  36. Peer– review process:
    Other ppl have read your research and agree on your research and methodology. Once accepted ~year later its publish.
  37. What are the goals of science? (if listed out make sure you could recognize
    • Description of behavior
    • Prediction of behavior
    • Determine cause of behavior
    • Explanation of behavior
  38. What 3 things must happen to determine causal relationship?
    1. Temporal Precedence: Cause must proceed effect

    • 2. Covariation of Cause & effect:
    • when cause is present effect occurs

    • 3. Elimination of all others- Difference between basic research & applied research (ex: program
    • evaluation DARE)
  39. - Difference between basic research & applied research (ex: program evaluation DARE)
  40. How do you correctly word a hypothesis?
    • A hypothesis can be supported or rejected
    • by the research

    • We never say “we have proven” or “we proved” because there can be a level of
    • error.

    • Use
    • If hypothesis was correct we say:
    • “Our research supported our hypothesis”

    • If our hypothesis was incorrect you state that by saying “our hypothesis was
    • rejected..”
  41. What is included in the anatomy of research article?
    • Abstract
    • Intro
    • Method
    • Results
  42. Difference between PSYCINFO & PSYCARTICLES
    PSYC Info: Computer based, Put out by American psychological association, only shows abstracts, then can be sent to full text if available.

    PSYCArticles: Can get full text articles
  43. What is social science index?
    • Allows you to do key article methods
    • It gives you a list of all articles that sited that article which you searched.
  44. Zimbardo Prison Study
    Participant Makeup:
    Length of Exp:
    Why was it ended early?
    • 1971
    • Standford Basement
    • Male College Students
    • Assigned roles = Guards psychological toture
  45. Belmont report reflects:
    Define Beneficence:
    Define Autonomy:
    Reflects APA ethics code.

    Beneficence: Principle that research should have more beneficial effect and minimal harmful.

    • Autonomy: principles of individuals can make decision to
    • participate or not. NEED INFORMED CONSENT. – Need signature – Minors cannot consent/mental retardation/major mental illnesses like schizophrenia.  Parents must consent for child and then child
    • must give assent.

  46. Is it ok to use Deception:                                           

    What is IRB –
    Deception: Still ok to use – but should be the last resort – and debriefing must be done ASAP – Access to professional help.                          

    IRB – Institutional review board: reviews research and approves it or not – one member from outside source
  47. Differences between lab & field research
    Lab research: greater control over extraneous variables.

    Field research: We might lose control but responses may be more authentic
  48. Interval Scales:
    Ratio Scale:
    Ordinal Scale:
    Nominal Scale:
    • Interval Scales:involves meaningful and equal differences between the values        on the scale (things with NO true zero)
    • ex:e.g., temperature, Elevation -- Time --
    • Ratio Scale:involve an absolute zero point that indicates the absence of the   variable being measured. ( it CAN HAVE a true zero)
    • Ordinal Scale:involve rank ordering (and numerical values are limited not  precisely measurable)
    • ex:movie ranking - One star, Two stars, Three stars, Four stars Freshman, Sophomore, Junior, Senior.

    Nominal Scale:involve categories (and have NO numerical or quantitative properties)
  49. Give an example of each of these:

    Naturalistic Observation:
    Systemic Observation:
    Case Study:
    Archival Research:
    Systematic observation: usually in lab & already have hypothesis generated.

    Case study: Usually conducted if someone possesses a rare trait.

    Archival research: No need for informed consent * how to we know if data is reliable.
  50. The Belmont Report outlined what 3 basic ethical principles:
    • Beneficence
    • Autonomy
    • Justice
  51. Tuskegee Syphilis Study, in which ___  poor
    African Americans in ______ were not
    treated for syphilis in order to  track the long-term effects of the disease even after _______ was discovered.
    • 399 of 600
    • Alambama
    • Penicillin
  52. Types of criterion-oriented validity: (4)

    • 1)  Predictive validity – scores on the measure predict behavior on a   criterion measured at a time in the future
    • eX: students who score high on LSAT it also reflects on their grades.
    • 2)Concurrent validity – scores on the measure are related to a  criterion measured at the same time.
    • ex: ppl score high on shyness scale & also score high on stress response in social setting.
    • 3) Convergent validity – scores on the measure are related to other measures of the same construct.
    • Ex: when ppl score high for depression they also score high on another consctruct for depression.

    4) Discriminant validity – scores on the measure are NOT related to  other measures that are theoretically different.
