Web Lecture #3: Developmental Research We also discuss several other topics like Which tissue allows our body to respond to stimuli?

Summary of Topics

→ Goals of Science Don't forget about the age old question of What do quotas do on the amount of imported goods?

→ Methods for Description

→ Correlational Designs

→ Experimental Designs

→ Experimental Variables

→ Ethics in Research We also discuss several other topics like How could process that begins postsynaptically (in dendritic spines) cause presynaptic changes?

Goals of Science

  1. Description - obtain accurate record of what's been observed
  2. Explanation - assign meaning to observed behavior (association or causation)
  3. Optimization - improve quality of life (Head Start program)

Don't forget about the age old question of How does the tryptophan operon work?

Methods for Description ★ can be used individually or in combination★

→ Observation

  • Lab = control setting
  • Naturalis = real world setting

We also discuss several other topics like What are 3 primary ethical guidelines involved in social research?

→ Interviews or Questionnaires

  • tendency for participants to answer questions based on society and not true feelings

→ Standardized tests

  • provide info about individual differences among people

We also discuss several other topics like What is an example of inoculation?

→ Life History Records

  • records of info about a lifetime chronology of events and activities (education, work, family, etc.)

→ Case Study

  • in-depth look at one person

Explaining Associations and Causation

Association → correlational design

Causation → experimental design

"Strength of Association"

→ x and y

→ statistical range

                +1.00. . . . . . . . . . . . .         0.00 . . . . . . . . . . . . . . . . . . . . . . . . . .-1.00

Strength:        strong                        weak                                        strong

Pattern:        positive                                                        negative

                Same direction                                                opposite direction

Experimental / Design Variables

→ Independent variables: potential causes that can be manipulated

→ Dependent variables: aspects of behavior that can change in relation to changes in

independent variables

Causation

→ randomly select two groups to participate

→ obtain a measure of the dependent variable

→ introduce the independent variable (x)

→ measure the dependent variable again (post-test)

        

        R        O        X        O        ← experimental group

        R        O                O        ← control group

Solomon 4 - Group Design

→ introduced a third group

→ doesn't administer the "pre-test", thereby eliminating any possible contamination

→ adds 4th group to control for the interaction of the pretest and the independent variable

Ethics in Research

  1. Informed consent.
  2. Confidentiality
  3. Debriefing
  4. Deception
