An overview of development research, focusing on qualitative and quantitative methods and memory types. Qualitative research includes surveys, dialogue, interviews, and ethnography, while quantitative research uses hard numbers and experiments to determine relationships statistically. Memory types include sensory, working, and long-term memory. The document also touches upon issues with research, such as bias and sampling errors, and discusses the differences between behaviorism and cognitivism, as well as implicit memories.
