5. Types of psychological hypotheses and the methods of research corresponding to them.

Lecture



The methods of psychological research presuppose forms of collecting empirical data that make it possible to test hypotheses of a particular type. A method is a way of organizing a study in order to test the hypothesis that has been advanced.

Two main groups of research methods can be distinguished:

  1. Passively observing (the observation method, the correlational approach)

  2. Active experiment (experiment, quasi-experiment, longitudinal study, cross-cultural studies, psychogenetic studies)

Method

Hypothesis

Observation

Descriptive

Correlational approach

About relationships between variables

Experiment

Causal hypotheses

Quasi-experiment

Causal hypotheses, limitation of the forms of control

Longitudinal study

About changes or about development

Psychogenetic methods

Quantitative psychogenetic models (about the influence on phenotypic variability of genetic and environmental factors and genotype-environment interactions.

Experimental-genetic (Vygotsky)

About the formation of mental functions

Method of stage-by-stage formation

Cross-cultural

The modeling approach; hypotheses about the structural-functional characteristics of the processes under study.

Hypotheses about cultural and social relations

The survey method and the interview method are procedures that serve as ways of collecting data but not as ways of organizing a study. The psychodiagnostic method is the subject matter of psychodiagnostics, whose tasks are solved on the basis of various approaches, methods, and techniques. Psychological measurement is likewise the subject matter of a related discipline that includes experimental procedures as means of establishing functional quantitative relationships.
