Study Notes
Social Validation
- Videos with a high number of likes are more likely to be viewed due to social validation and the inclination to conform to popular opinion.
- This study uses a 4-point rating scale to ensure consistent measurement and eliminate a "middle ground".
Multiple Levels of an Independent Variable
- An experiment with multiple levels of an independent variable (IV) can help explain causal relationships and detect non-linear relationships.
- Example: Studying the effect of happy vs sad mood on memory requires multiple levels of the IV "mood".
Four Goals of Psychological Research
- Description: Focuses on understanding the current state of affairs.
- Prediction: Focuses on anticipating future events based on existing relationships.
- Finding Causes: Focuses on identifying the factors that directly influence an outcome.
- Explanation: Focuses on providing a comprehensive understanding of why things happen the way they do.
Basic vs Applied Research
- Basic research: Aims to understand the underlying mechanisms of behavior and is often not immediately applicable to everyday life.
- Applied research: Aims to improve human well-being and everyday functioning by leveraging theories developed through basic research.
Terminology in Psychological Research
- Idea: A preliminary thought or concept about a phenomenon.
- Theory: A well-organized set of principles explaining how a phenomenon operates.
- Hypothesis: A statement predicting the relationship between two variables, often derived from a theory.
- Model: A metaphor or representation used to understand a particular aspect of the human experience.
Fuzzy Trace Theory
- This theory posits that memories are stored in two forms: verbatim (accurate) and gist (inaccurate).
- Time pressure increases reliance on gist memory, potentially interfering with verbatim memory retrieval.
Therapies and Treatments
- CBT/Mindfulness therapy demonstrates efficacy in reducing anxiety compared to sham therapy (placebo) and treatment-as-usual conditions.
- The mindfulness component plays a significant role in the therapy's effectiveness.
Single-Case Baseline Design
- This design involves establishing a baseline measurement of the dependent variable (DV) and then observing changes in the DV after manipulating the independent variable.
- It helps identify patterns and potential causal relationships related to specific interventions.
ABA Reversal Design
- This design involves alternating baseline conditions (A) with intervention conditions (B) to observe changes in the DV.
- The design helps determine the direct effect of the intervention by comparing behavior during baseline and intervention phases.
Multiple Baseline Design
- This design aims to generalize single-case study findings by replicating the intervention across different participants, behaviors, situations, or operational definitions of the IV or DV.
- It increases the generalizability and validity of findings by demonstrating consistent effects across diverse contexts.
Quasi-Experiments
- Resemble experiments but lack the strong internal validity of true experiments due to limitations in control or manipulation of variables.
