Abstract

This course reviews general techniques and methodologies for a research project in cognitive science: literature review, hypothesis making, experimental design, data analysis, statistics, and inference. Students learn these techniques and methodologies with theories behind them and have some practices of them in the course. The course is designed to provide the knowledge and competencies necessary to plan and conduct their research projects in cognitive science.

Course Contents

Course Contents

  • Cognitive science as a field of science
    How cognitive science can be science. Practical/theoretical limitations in cognitive science. Properties of data obtained from human beings. Reductionism in science and unavoidable holism in cognitive science. Statistics as a descriptive method. Research ethics.
  • Starting a research project
    A process determining research topic and formulating a project. Literature review: choosing/changing its keywords, checking back earlier studies, checking recent relevant studies using article search engine. Finding interest and formulating question and hypothesis. Types of questions, theories, and scientific explanation. Research ethics: human participants and animal subjects, research misconduct (e.g. plagiarism, forgery), questionable research methods.
  • Sampling and data collection
    Sample as an indicant of general population: representativeness and sample bias. Types of data: behavioral, physiological, neuroscientific, and archival. Methods of collecting behavioral data: adjustment method, multiple forced choice, and reaction-time. Psychophysics.
  • Experiments and quasi-experimental and non-experimental plans
    Experimentation. Types of variables. Experimenter and respondent biases. Betweengroups designs and within-groups designs. Fixed and random factors. Intentional confounding: Latin squares. Quasi-experimental plans (manipulation without complete control) and non-experimental (correlational) studies. Cross-sectional (between-groups) designs, longitudinal (withingroup) designs, and mixed (multiple cohort longitudinal) designs. Ex post facto designs. Specific non-experimental plans: twin studies, cross-cultural studies.
  • Data organization and visualization
    Row data and its process using software (e.g. Excel, Matlab, R). Graph plotting. Organizing data for further analysis.
  • Statistical methods 1: t-test, regression, repeated-measure ANOVA, ANCOVA, Chi-square-test
    Conventional statistical methods: t-test, regression, repeated-measure ANOVA, ANCOVA, Chi-square-test. The null-hypothesis. Effect size and statistical power. Analyzing distributions: normality test. Power analysis: conventional methods and Monte-Carlo method.
  • Statistical methods 2: Likelihood analysis, Bayesian statistics
    Curve fitting, MCMC, Bayes factor
  • Meta-analysis on behavioral studies
    Data collection, Forrest plot, Funnel plot, Publication-bias.
Assessment Elements

Assessment Elements

  • non-blocking home assignments
    8 home assignments; Its weight in grading is 0.3. The 1st-retake of a home assignment is evaluated in the same way as the original assignment. The 2nd-retake of the assignment comes with 20% of penalty on its score. Namely, its score is first computed in the same way as the original assignment and then the computed score is multiplied by 0.8.
  • non-blocking Writing tests
    2 writing tests around the end of the 1st and 2nd modules; Its weight in grading is 0.3. The 1st-retake of a test is evaluated in the same way as the original test. The 2nd-retake of the test comes with 20% of penalty on its score. Namely, its score is first computed in the same way as the original test and then the computed score is multiplied by 0.8.
  • non-blocking Final writing test
    The test (3rd module of 2019-2020) has been already performed in a period 10 days before the exam week in accordance with course program. No further exam required. Экзамен проводится в письменной форме (тест по материалам курса). Экзамен проводится на платформе Zoom (https://www.zoom.us/). Компьютер студента должен удовлетворять требованиям: наличие рабочей камеры и микрофона, поддержка Zoom. Для участия в экзамене студент обязан: поставить на аватар свою фотографию, явиться на экзамен согласно точному расписанию, при ответе включить камеру и микрофон. Во время экзамена студентам запрещено: выключать камеру, пользоваться конспектами и подсказками. Кратковременным нарушением связи во время экзамена считается нарушение связи менее минуты. Долговременным нарушением связи во время экзамена считается нарушение длиной в минуту и более. При долговременном нарушении связи студент не может продолжить участие в экзамене.
