Study Notes

Consistent Procedures in Studies

  • Importance of consistency: Procedures must be consistent within and between conditions.
  • Planning for consistency: Careful planning at instruction stage is needed.
  • Instructions: Instructions should clearly detail the task, stimulus sequence, and responses.
  • Automation: Using automated equipment (timers, projectors) for stimulus presentation improves consistency.
  • Pilot studies: Small-scale trials (pilot studies) help assess instructions, task feasibility, and equipment effectiveness.
  • Group testing: Group testing is efficient but potential for noise and distraction from other subjects needs to be controlled.
  • Manipulation checks: Used to confirm that independent variables had the intended influence on the dependent variables.
  • Example of manipulation check: Measuring anger after manipulating frustration.
  • Ensuring reliability and validity: Multiple procedures for controlling threats to reliability and validity.

Phases/Stages in Research

  • Tedious and time consuming: Research is a prolonged and challenging process.
  • Steps for smooth research: Following steps can streamline the research process.
  • Identifying the problem: Defining a suitable, unambiguous problem showing a relationship between at least two variables.
  • Reviewing the literature: Examining existing research to understand relevant variables, variables' conceptual understanding, and practical importance.
  • Formulating a hypothesis: A tentative statement about the relationship between variables. It should be consistent with existing knowledge, testable, reasonable, and expressed simply.
  • Data gathering process: Hypothesis formation should precede data collection.

Variables

  • Variables: Factors or attributes measured in an experiment or investigation.
  • Three types: Dependent, independent, and extraneous.
  • Dependent variable (DV): The characteristic expected to change in response to the manipulation.
  • Independent variable (IV): The variable manipulated or selected by the researcher.
  • Extraneous variable: Uncontrolled variable that can affect the dependent variable.

Research Design

  • Blueprint for procedures: Detailed plan for testing relationships between variables.
  • Purposes and considerations: Purpose of research, variables of interest to be controlled, experimental environment influence the research design.
  • Observation and measurement tools: To support the research, questionnaires, interviews, and other data collection tools should be used.

Summarizing Results

  • Methods of summarizing: Results are summarized using tabular and graphic methods.
  • Tabular method: Data condensed into tables; used for statistical analysis.
  • Graphic method: Data presented in graphical form, providing visual representation
  • Using multiple methods: Combined use of both methods for clarity and complete data representation.

Statistical Analysis

  • Data analysis: Determining if the results support or reject hypotheses.
  • Choosing appropriate method: Selection is dependent on data type and research purpose.
  • Parametric tests vs. non-parametric tests: Different statistical approaches applied based on the data and study design.

Types of Research

  • Historical research: Investigation, recording, and analysis of past events for future understanding.
  • Descriptive research: Records conditions, describes relationships between variables, and makes interpretations.
  • Experimental research: Manipulating variables to determine relationships.

Types of Variables

  • Quantitative: Variables with measurable magnitude, ordered in magnitude.
  • Qualitative: Variables defined by categories, no inherent order.
  • Continuous variables: Measured with any degree of fineness, e.g., age, height.
  • Discrete variables: Measured by counting, e.g., number of family members or items in inventory.
  • Moderator variables: Variables affecting the relationship between variables of interest.
  • Intervening variables: Hypothetical constructs between independent and dependent variables.
  • Active variables: Manipulated by research.
  • Attribute variables: Characteristics of subjects (e.g., age, sex), not directly manipulated, but could influence results.
  • Subject relevant variables: Characteristics of subjects controlling or influencing the outcome.
  • Situational variables: Environmental conditions influencing the subject's reaction to stimuli or tasks.
  • Sequence relevant variables: Variables related to order of presentation or experimental conditions influencing results(e.g.,practice,fatigue).

Drawing Conclusions

  • Generalization: Extracting conclusions from the study's results for broader context
  • Predictions: Extrapolating to similar situations or contexts.
