L12-L14 Flashcards
3 approaches to generating research ideas
deduction, induction, abduction
Deduction
top-down approach that is used to determine how existing general information can be applied to a specific instance
Steps in deduction
If P then Q; P, therefore Q
Theory
overarching framework that organizes and explains phenomena and data; generates a hypothesis that test the boundaries of the theory
Hypothesis
a tentative statement about a relationship that may or may not be true
Prediction
specific statement regarding the expected outcome of a study
Induction
bottom-up approach that goes from an observation to a hypothesis to a theory or general expectation (may lead to logical errors)
Abduction
used to identify the simplest and most probable explanation of a phenomena or observation
Difference between abduction and induction
abduction does not lead into a theory or general explanation, rather it leads into an explanation for a specific observation
Steps in abduction
If P then Q; Q, therefore P
Type of data in qualitative vs quantitative research
textual, narrative, personal experience; numerical
Goal of qualitative vs quantitative research
descriptive (to develop a good understanding of a phenomenon); to identify social regularities by comparing and contrasting different groups
Type of research (or reasoning) in qualitative vs quantitative research
inductive (to induce a theory); deductive (to test a theory)
Methods in qualitative vs quantitative research
unstructured or semi-structured questions; structured or closed-ended questions
Sample size in qualitative vs quantitative research
very small due to large amount of data gathered from each participant; large
Generalizability in qualitative and quantitative research
good if random sampling is used (equal chance of recruitment) and depends on ratio of sample size to population
5 kinds of measures used in quantitative research
explicit, implicit, physiological, neurological, behavioral
Explicit measures
asking participants to directly report their thoughts and emotions (e.g. self-report questions)
Implicit measures
measures for attitudes over which participants have no conscious control (e.g. associations that imply racism)
Neurological measures
use of neuroimagery techniques to determine neurological changes and the role of neural structures
Behavioral measures
measures actual behaviors that are proxies for a psychological construct (i.e. conceptual dependent variable)
Physiological measures
measures the body’s automatic reactions to stimuli, excluding changes in the brain (e.g. galvanic skin response)
