Title: Methods of Cognitive Science


1
Methods of Cognitive Science
  • Theoretical, conceptual work
  • Imagery debate reality of mental concepts
    capacities of home erectus
  • Observation and clinical case studies
  • Use of mental state verbs in 1-3 year olds
  • Deceptive behavior of chimpanzees in the wild
  • Autism, schizophrenia, lesion studies (e.g.,
    S.M., who lacks amygdalae and neither experiences
    nor recognizes fear)
  • Surveys and questionnaires (rare)
  • Judgments of intentionality

2
Methods continued
  • Quasi-experiments and group comparisons
  • Imaging work (e.g., planning/perceiving/performing
    act)
  • False belief tests with 3-4 year olds
  • Clinical group comparisons (e.g., face processing
    in autistic vs. other individuals)
  • Controlled experiments
  • Word learning under various conditions
  • Boundaries of behavior stream
  • Dishabituation paradigm
  • The logic of causal inference
  • The alternative explanations game

Vocabulary
  • Independent/dependent variable
  • Measurement, operationalization, Reliability and
    validity
  • Experimental and control condition
  • Cross-sectional vs. longitudinal
  • Derive hypotheses, test predictions
  • Sampling, representativeness generalizability

4
Basics of Statistics
  • Descriptive vs. inferential
  • Key concepts of
  • sampling
  • variance (standard deviation, SD)
  • estimate (mean 95 confidence interval)
  • Correlation coefficient
  • Univariate and multiple regression
  • Analysis of variance (ANOVA) designs
  • Two or more groups in one factor (e.g., 3 x 1)
  • Multiple factors (e.g., 2 x 2, 3 x 2 x 2)
