Population

group of interest

New cards
35

Sample

subset of population

New cards
37

Double Blind

researcher nor participant know how the participant are expected to behave

Rosenthal & Fode study

  • some students asked to measure speed rat learned to navigate maze

  • some were told rat was slow learner, others were told the bred was fast learner

  • students who thought they were measuring slow learner reported rat took longer to navigate ( AND VISE VERSA)

    RESULTS

  • expectation can influence observation and reality

  • The student’s expectations influenced their rats behavior and their observation of it

New cards
43

Independent variable

variable manipulated

  • varies within experiment

  • determined by experimenter

  • Ex: presence/absence of aggressive behavior in film

New cards
44

Dependent variable

variable possibly affected by manipulation

  • measurement made by experimenter

  • Ex: count number of punches to doll

New cards

E: subjects who receive some special treatment in regard to the independent variable

C: similar subjects who do not receive the special treatment

  • Glial cells: structural support & insulation

  • Synapse: point at which neurons interconnect ( there is a gap)

New cards
52

Action potential

a shift in electrical charge that travels along the axon of neurons

( think of hand wave that happens at sport games)

New cards
53

    • activates muscles

    • attention, memory, learning
