The November 2020 GCSE Psychology Paper 1 explores cognition and behavior across memory, perception, development, and research methods. Topics in memory include the multi-store model, Bartlett’s study, and reconstructive memory theories. Perception addresses binocular depth cues, visual illusions, and cultural influences. Development focuses on cognitive stages, Hughes’ egocentrism study, and self-efficacy in learning. Research methods evaluate experimental designs, ethical considerations, and data types like qualitative versus quantitative. Applications include the relationship between physical exercise and mental well-being, with statistical analysis and scatter diagrams. Keywords: psychology, memory, perception, development, research methods, cognitive stages, reconstructive memory, experimental design.
