The cognitive psychologists were strongly influenced by the computer revolution and often use models to help aid understanding of how we acquire, store, and retrieve information. Cognitive psychology focuses on how cognitive psychologists interpret the world. It includes exploring perception, thinking, language, attention, and memory. Forgetting from the short-term memory may be due to interference or decay. The multi-store model formed the basis for much research into memory, leading to other models being proposed. Research into the working memory model focuses on performing tasks that use either the same or different systems, sometimes known as the dual-task technique. Most methods for improving memory stress the need for organising the material, both at the time of learning and storage, and at the time of retrieval and recall. Research exploring ageing and memory raises ethical concerns about the publication of these research findings.
