The June 2019 GCSE Psychology Paper 1 examines cognition and behavior across four sections: memory, perception, development, and research methods. Topics include memory theories like reconstructive memory, context-dependent memory, and interference. Perception explores visual illusions, depth cues, and theories such as Gibson’s direct theory. Development addresses Piaget’s cognitive stages, Willingham’s learning theory, and learning styles. Research methods focus on ethical considerations, hypothesis formulation, data reliability, and graph creation. Applications of psychological theories to real-life scenarios, such as emotion affecting perception and observational studies on phone usage, are emphasized. Keywords: psychology, memory, perception, development, research methods, cognitive theories, ethics.
