PSYB01H3 Chapter Notes - Chapter 11: Measuring Instrument, Random Assignment, Internal Validity
Document Summary
Chapter 11 single case, quasi-experimental, and developmental. In chapter 8 we looked at classic experimental designed in which participants are assigned to experimental controls and a variable is manipulated. This chapter will look at 3 types of special research circumstances. The first is an instance in which the effect of an independent variable must be inferred from an experiment with only one participants a single case study. The second we will describe pre-experimental and quasi-experimental designs that may be considered if it is not possible to use true experimental designs. Third, we will look at research designs that study changes that occur over age. Single case experimental designs have traditionally been called single-subject designs but are now called single case designs (barlow and hersen, shadish, Cook, and cample) and single participant (morgan and morgan) Early interest in single case designs in psychology came from b. f. skinner"s work with reinforcement.
