Comprehensive Study Guide: Research Design, Quantitative Methodology, and Lab Workflows

Lab Mechanics, Workflows, and Document Templates

• Lab Room Spatial Allocation:

  • Physical seating assignments are designated by group numbers across specific lab room sectors (e.g., Group $1$ is positioned in the top area of the lab room).

• Lab Instruction Documents & File Conversion:

  • Full lab instructions and guided templates are hosted on Canvas.
  • To enable collaborative editing, students must download the instructional document and upload it to Google Drive to convert it into a Google Doc format.
  • Document Structure:
    • Pages 1–3 (Part A): Focuses on research topics, literature deep dives, guided response templates, and text-box entries.
    • Page 4+ (Part B): Covers hypotheses development, study methodology, and ethics considerations.

Team Dynamics, Communication Standards, and Assignment Division

• Professional Communication Protocols:

  • Group success relies on active participation and direct, professional communication among present members.
  • Teams must maintain a clear operational record identifying completed tasks and missing deliverables.
  • Informal text-style inquiries (e.g., asking "Where quiz at?") via Canvas messages are prohibited. Academic queries must be directed to the instructor via formal email, while routine peer updates belong in direct group messaging channels.

• Non-Burden Shifting Policy:

  • If a team member fails to contribute required inputs (e.g., missing answers from Team Member B), present members must not absorb or complete the missing work.
  • The missing item must be explicitly annotated on the submission before moving forward.
  • Lab activities serve as skill-building practice for individual writing assignments. Absent or non-contributing students forfeit their opportunity to build research skills and gather material for their individual drafts.

• Literature Search Workload Division:

  • Lab 1 Assignment: Requires a minimum of $3$ to $5$ peer-reviewed research articles per team ($3$ absolute minimum).
  • Introduction Draft (M1 Draft): Requires a minimum of $5$ peer-reviewed articles per individual student.
  • Workload Distribution: In a group of $3$, members divide the task so each person finds $1$ article for the collaborative lab. For the individual M1 draft, each student adds $2$ unique articles to the $3$ shared sources to reach the $5$-article requirement.
  • Shared sources across team members are fully permissible given that all members analyze the same underlying study design; however, all individual writing must remain distinct.

Fundamentals of Research Design, Variables, and the Research Cycle

• Variable Taxonomy:

  • Predictor Variable: An observed or manipulated variable hypothesized to influence, explain, or cause changes in an outcome.
  • Outcome Variable: A measured variable that reflects the impact, effect, or result of the predictor variable.

• Classification of Research Designs:

  • Descriptive Design: Focuses on observing, measuring, and documenting specific phenomena or behaviors as they naturally occur.
  • Correlational Design: Evaluates whether two or more non-manipulated variables share a systematic association or relationship, without establishing causality.
  • Experimental Design: Involves direct manipulation of an independent variable (predictor factor) and controlled measurement of a dependent variable (measured outcome) to evaluate if $X \text{ causes } Y$

• The Iterative Research Cycle:

  • Scientific inquiry follows a continuous loop: Theory $\rightarrow$ Hypothesis Formulation $\rightarrow$ Experimental/Study Design $\rightarrow$ Data Collection & Analysis $\rightarrow$ Results Evaluation $\rightarrow$ Theory Refinement $\rightarrow$ Repeat.

Theory Integration, Literature Gaps, and Psychological Constructs

• Integrating Theory and Identifying Gaps:

  • Hypotheses must derive from established theories applied to novel research questions.
  • Literature reviews must target unresolved "gaps" in current research—such as unobserved variables, unexamined moderating factors, or conflicting theoretical models.
  • Competing Theories: Research design frequently pits opposing theories against each other to determine which best accounts for observed behavior (e.g., the historical Nature vs. Nurture debate, now recognized as an interaction of both).
  • Institutional Delays in Theoretical Integration: Diagnostic manuals, such as the Diagnostic and Statistical Manual (DSM), often take decades to update and integrate emerging biological theories alongside psychological models due to prolonged theoretical debates.

• Identifying Psychological Constructs:

  • Constructs are underlying psychological attributes, themes, or theoretical entities synthesized from empirical observations.
  • Examples of Empirical Synthesis to Constructs:
    • Observations of reduced attention span and impaired memory retrieval $\rightarrow$ Working Memory construct.
    • Reports of persistent exhaustion despite adequate hours of sleep $ ightarrow$ Sleep Deprivation or Sleep Quality construct.
    • Observed variations in parental discipline, warmth, and control $ ightarrow$ Parenting Styles construct.
    • Reliance on family and community networks during hardship $ ightarrow$ Social Support construct.

• Scope Management: Topics vs. Research Questions:

  • Research progression requires narrowing a broad topic into a specific, testable question.
  • Avoid Over-Specification ("Devolving"): Overly restricting a study population too early (e.g., limiting criteria strictly to $19$-year-old college students on academic campuses) invalidates relevant empirical literature conducted across broader age groups or non-academic settings.

Case Study: Developing Feasible Research Questions on Academic Stress

• Deconstructing Broad Topics:

  • Broad Topic: College student stress.
  • Categorizing Stress Domains: Personal life/responsibilities, financial/income strain, or academic stress (workload, course volume, concurrent academic pressures).

• Evaluating Research Questions (Specific, Measurable, Feasible, Ethical Criteria):

  • Initial Research Question: "How do college students manage stress during finals week?"
  • Evaluation:
    • Specific: Yes (focuses on college students, stress management, and finals week).
    • Measurable: Yes.
    • Ethical: Yes.
    • Feasible: No. Data collection and analysis during finals week directly overlaps with final presentation deadlines, preventing students from processing data in time for course evaluation.
  • Feasibility Adjustment: Shift the operational window from finals week to midterm exams, allowing data collection during peak stress while leaving sufficient time for analysis and presentation preparation.

• Formulating Hypotheses from Literature Consensus:

  • Literature Finding: Multiple empirical studies report that mindfulness training interventions significantly attenuate stress levels.
  • Derived Hypothesis: "If mindfulness training reduces stress, then students who participate in mindfulness training will report lower stress scores than those who do not participate in mindfulness training or programming."
  • All hypotheses must undergo CITI ethics review principles to identify potential risks or harm.

Institutional Support and Research Consultation Resources

• Psychology Subject Librarian Support:

  • Assigned Librarian: Lauren (Psychology Subject Librarian).
  • Role: Master's-level professional research specialist who provides specialized guidance on psychology database navigation, literature searches, and methodology structuring.

• Additional Academic Support Services:

  • SJSU Writing Center.
  • Campus academic tutoring support services.

Quantitative Sampling Requirements, Population Criteria, and Final Paper Directives

• Statistical Sample Size Thresholds ($N$):

  • In quantitative research, $N = 30$ serves as the standard baseline threshold for parametric statistical analyses.
  • Sample sizes below $N = 30$ significantly increase statistical error margins, causing analytical software to flag results as unstable.

• Group Workload Collection Rules ($10$ Participants per Student):

  • $2$-Member Team: Required target range of $20$ to $30$ participants ($30$ required to maintain statistical power and avoid point deductions on final presentation evaluations).
  • $3$-Member Team: Minimum of $30$ participants ($10$ per member).
  • $4$-Member Team: Minimum of $40$ participants ($10$ per member).
  • $5$-Member Team: Minimum of $50$ participants ($10$ per member).

• Permissible Sampling Population Categories:

  1. SJSU Students Only: Excludes students currently enrolled in this specific lab section to eliminate response bias.
  2. General College Students: Permissible only if the specific college or university of each respondent is recorded as a control variable.
  3. SJSU Community Members Only: Strictly defined as SJSU alumni, staff, current students, or direct immediate community members residing in the immediate zip code who interact directly with SJSU (e.g., family members or friends assisting with campus move-in or administrative paperwork).

• Final Paper (M5 Assignment) Guidelines:

  • M5 document instructions outline the cumulative final paper requirements hosted in the Canvas module.
  • Warning: Students are explicitly forbidden from using the final M5 document as a template to write ahead of assigned milestones. Premature drafting creates group desynchronization, severe communication failures, and unnecessary stress. Research writing must proceed sequentially through assigned drafts (M1, etc.).

Literature Search Management and APA Synthesis Protocols

• Literature Search Organizer Template:

  • Managed via a standardized Google Sheet template.
  • Required Tracking Fields:
    • Citation Metadata: Author, Year, Title, Journal Title, Volume Number, Issue Number, DOI Link.
    • Methodological Details: Research design (experimental, observational, interview, survey, mixed-methods), analysis type, sample size, population context.
    • Synthesis Notes: Key empirical findings, theoretical implications, and direct relevance to the research question.
