Scientific Method Steps
Identify the problem, Develop research, identify and develop research design, develop and identify techniques/instruments, collect & analyze data, draw conclusions, report the data
External Validity: Multiple-Treatment Interference
In some studies, participants are exposed to multiple treatment conditions• Makes it difficult to draw conclusions about a given treatment when it is evaluated in the context of other treatments
Quantitative Research Designs
Research that is based on measurement and quantification of data (i.e., all data turned into numbers)
Descriptive Designs 4 types:
Survey: involves the use of self-report to clarify the perceptions, attitudes, or behaviors of a target group• There is no IV• Data is collected solely to describe some aspect of a particular group• Observational: involves observing the behavior of a target group• This design still clarifies personal characteristics , but avoids problems of self-report• Correlational: used to identify and understand the relationship between multiple variables or how several variables of interest covary• Cannot draw any conclusions regarding causation• For some great examples, go here: Causal-comparative: used to identify effects of an IV after the fact• The IV is outside the researcher's control• The researcher compares two or more groups who had different experiences (experiences = the IV)• This is a quasi-experimental design
Construct Validity
The conceptual basis (construct) underlying the effect
external validity: test sensitization:
The effect of a previous test on subsequent performance • Purpose of a pretest is to measure the participant's standing on a particular variable before that person receives the experimental manipulation or treatment • Pretest sensitization: the effect of a pretest on a person's response to an intervention • Results may not generalize to people who did not have the pretest
Testing
The effects that taking a test once can have on subsequent performance•
Statistical Conclusion Validity [COVERED WITH RESULTS]
The extent to which a relation is shown and the extent to which the experiment detects effects if they exist
External Validity: sample characteristics
The extent to which characteristics of the sample represent the target population
Internal validity
The extent to which the intervention can be considered to account for the results (as opposed to a confounding variable) • Relates to the amount of control researchers had over the study
External validity
The extent to which the results can be generalized to circumstances other than those in the particular experiment• Relates to how true to life (generalizable) the study is•
Statistical Conclusion validity
The extent to which we can be certain that the researcher has drawn accurate conclusions about the statistical significance of the research.

Maturation
• Changes over time that result from physical/psychological processes within participants
Variables:
• Dependent variable• Changes as a result of changes in independent variables: Dependent variables depend on independent variables Extraneous variable: Uncontrolled and/or unknown variables that can impact the dependent variable, Not controlled by the researcher Control Variables: An extraneous variable that the researcher has identified and addressed in the method• Three methods for controlling for extraneous variables• Build the variable into the design and control for its effects (make it an independent variable)• Remove possible effects of the extraneous variable (sample from one level of the variable)• Control through statistical methods after the study has been conducted (e.g., use an ANCOVA)
external validity: History & Treatment Interaction
• Events occurring at time of treatment/intervention may affect outcome• Hard to control this, but can address by extending study beyond impact of uncontrolled event
Attrition
• Loss of participants • Problem in longitudinal studies • Direct function of time • Most people drop out early• May lead to systematic differences between the groups• Differential attrition across groups • Participants more likely to remain in study if they are doing something interesting, something that has little or no cost or adverse side effects, seems plausible, and is effective
External validity: Reactivity of assessment
• Most psychological assessments are obtrusive • If awareness of assessment leads people to respond differently, we call that reactive • Need to determine whether the changes carry over to people's actual experiences in their everyday lives
Threats to external validity
• Sample Characteristics • Interaction Between Sample and Treatment • Stimulus Characteristics and Settings• Reactivity of Experimental Arrangements • Multiple-Treatment Interference • Novelty Effects • Reactivity of Assessment • Test Sensitization • Timing of Measurement•
Selection Biases
• Systematic differences between groups before any experimental manipulations or interventions
