  31. What is Research?
    Systematic and careful collection of Data (supports the theory or doesn't)
  32. Tools of scientific research: 
    What is longitudinal?

  36. What is descriptive research?
    observe and classify behavior with no intervention by observer (Naturalistic) or with intervention by observer (participant observation).
  37. Descriptive research: 
    What are case studies?
    Focus on a single interesting case in detail.
  38. What is an example of a case study?
    Example: interested in how parents and kids use media together on a daily basis? Do an in-depth case study of one family.
  39. What is a Survey/Self-report?
    Set of questions that asks participants directly about their beliefs, attitudes, preferences, or activities.
  40. What are Correlational studies?
    Relationships between 2 or more variables that are measured but NOT manipulated.
  41. What are some problems with correlational studies?
    There can be a confusion of because of directionality problem. An example would be did a cause b to happen? Or did b cause a to happen? or is there a third unknown variable.
  42. What is an independent variable in an experimental study?
    intentionally varied; experimenter manipulates
  43. What is an experiment?
    What are the advantages and disadvantages?
    • Examine how variables are related when manipulated by researchers.
    • Advantage: Can demonstrate casual relationships. Avoid the directionality problem
    • Disadvantage: often take place in an artificial setting.
  44. WHat is a dependent variable?
    Aspect of situation that is measured as IV is changed.
  45. What are Tools of scientific research:
    • Samples (the subset you study)vs. Population (the group you want to know about)
    • Random assignment (each member of each sample has equal chance of being assigned to each experimental group) vs. random sampling (each member of population has equal chance of being in your sample)
    • Convenience sampling (people available to you) 
    • Quasi-Experimental (not random assignment)
  46. In Bias research what do you have to worry about?
    • Reliability
    • Validity
    • Accuracy
  47. What is reliability?
    the extent to which a measure is stable and consistent over time and in similar conditions.
  48. What is validity?
    • The degree to which a test actually measures what it's supposed to measure. 
    • A measure can be reliable without being valid, but cannot be valid without being reliable.
  49. What is accuracy?
    the extent to which an experimental measure is free from error.
  50. Types of Bias in Research: 
    What is selection/sampling bias?
    • when participants are not selected at random from the population, such that certain aspects of the population are over or underrepresented in your sample 
    • Example: self-selection, convenience sampling
  51. Types of Bias research: 
    What is experimenter bias?
    • any intentional or unintentional influence that the experimenter exerts on subjects to confirm the hypothesis under investigation. 
    • Example: demand effects, expectancy effects. 
    • Example: addressed via a double-blind design-neither the experimenter nor the participants know the group to which ecah participant is assigned (experimental or control).
  52. Types of Bias research:
    What is response bias?
    • the tendency to respond a particular way regardless of their actual knowledge or beliefs.
    • Ex: self-report bias, reactivity
  53. Types of Bias in research:
    What is Observer bias?
    errors in observation due to the observer's expectations.
  54. Bias in research: Expectancy effects
    What is hawthorne effect (i.e., observer effect)?
    a type of reactivity in which the participant's behavior changes because they know they are being studied, not because of manipulation of the IV (independent variable).
  55. Bias in Research: expectancy effects
    What is Clever Hans?
    The experiment's involuntary behavior unintentionally cues the participant.
  56. Bias in Research: expectancy effects
    What is Pygmalion effects?
    • one's behavior is influenced by the expectations of others
    • E.g., Rosenthal's rats, effect of teachers' expectations of students on their learning outcomes.
  57. Bias in Research: Detecting confounds
    What are four confounds?
    • Design
    • controls,unexplained variables, experimenter biases/demand effects
    • Sample
    • adequacy, appropriateness, representativeness
    • Measures
    • adequacy,reliability, validity, accuracy
    • Conclusions
    • DO the conclusions that are bade follow logically from the data?
  58. What is a confound?
    anything that affects a dependent variable and may unintentionally vary between the experimental conditions of a study.
  59. What is Electroencephalograph (EEG)?
    • Non-invasive measurement of electrical activity in the brain via electrodes on the scalp. 
    • good temporal resolution, poor spatial resolution
  60. What is Positron emission tomography (PET)?
    • measurement of metabolic activity via ingestion of a radioactive substance that emits positron as it is metabolized.
    • Poor temporal resolution, good spatial resolution 
  61. What is Functional magnetic resonance imaging (fMRI)?
    • measure changes in blood-flow to specific brainregions in a magnetized field. 
    • Poor temporal resolution, good spatial resolution 
  62. WHat is Transcranial magnetic stimulation (TMS)?
    Temporary disruption of function of a specific cortical area via transmission of an electric field.
  63. Descriptive Statistics:
    • Summarize/organize scores from a research study
    • Measures of central tendency 
    • Mean-average
    • Median-middle
    • mode-most common
    • Variability and standard deviation
  64. Inferential statistics:
    Draw conclusions/make inferences that go beyond the scores from a research study.
  65. Meta-analysis:
    Combine the findings of multiple studies to arrive at a conclusion.
  66. What is Correlation coefficient?
    • A descriptive statistic that indicates the strength of the relationship between two variables. 
    • Ranges from -1.0 to+1.0
    • Closer to either extreme=stronger relationship
    • Closer to zero= weaker relationship
    • Zero=no relationship 
  67. What is a positive relationship? Hint: correlational coefficient
    The two variables increase and decrease together
  68. What is a Negative relationship? Hint: correlational coefficient
    as one variable increases, the other decreases.
