AP Psychology Quiz: Longitudinal, Cross-Sectional, and Sequential Designs

📚 Quick Study Guide

• ⏱️ Longitudinal Design: Studies the same group of individuals over an extended period.
• 📊 Cross-Sectional Design: Compares different groups of individuals at one point in time.
• 🔄 Sequential Design: Combines longitudinal and cross-sectional methods by studying multiple cohorts over time.
• ➕ Cohort Effect: A key consideration in cross-sectional studies, where differences may be due to generational experiences rather than age itself.
• 💡 Longitudinal Advantages: Can track developmental changes accurately.
• 📉 Longitudinal Disadvantages: Time-consuming, expensive, and subject to attrition (participants dropping out).
• 📈 Cross-Sectional Advantages: Quick and cost-effective.
• ⚠️ Cross-Sectional Disadvantages: Cannot determine cause-and-effect relationships.
• 📅 Sequential Advantages: Helps separate age effects from cohort effects.
• 💸 Sequential Disadvantages: Complex and resource-intensive.
