Developmental
, Approaches To research
Discuss sociocultural approach to research used to understand our developing as a learner.
Experiment
• Establishes cause-effect relationships
• Allows researchers to manipulate an independent variable and measure its effect on
dependent variable
• Other variables are keep constant to eliminate as many other factors that could
potentially influence the behavior.
• Participants are often randomly allocated to conditions
• Placebo is often used as a control condition → prevents demand characteristics.
PIAGET AND INHELDER
GIEDD (2004)
Manipulation of independent variables
• Exposing different participants to different conditions such as control and experimental
Measurement of dependent variables
• To record changes caused by manipulation of independent variable
Control over extraneous variables
• Limits the influence of extraneous variable on experimental results
• Helps to establish cause-effect relationship
Standardized procedure
• Ensures that procedure can be replicated
Research design
• Independent measures
• Repeated measure
• Matched pairs
Strengths Limitations
• Manipulation and control over variables • Could be unethical
→ Cause effect relationship • Isolation of external variables → artificial
• Standardized procedure → Replication → experiment → low external validity → low
validity ecological validity
• Control over variables allows to focus on • Participants might be fully aware that
one aspect of the study they are participating in a psychology
• Statistical analysis → organization and experiment → Reactivity effect
interpretation of data is easier • Participants might figure out the
hypothesis → Demand characteristics
• Reductionist
Field
• Can’t control confounding variables
• Can’t replicate it easily
Quasi and Natural
• Can only imply causal relationship.
