Introduction What is Cognitive Psych?  “The science of thinking” "Cognitive Psych refers to all processes by which the sensory input is transformed,  reduced, elaborated, stored, recovered, and used" Neisser (1967) (Father of Cognitive  Psychology)   Sensory Input: Perception is an active cognitive process 1. 1. All we learn about the world has to come in through one of our senses  2. We actively process this information  3. What we experience depends on how our brains process information Keep in Mind: Even basic processes like perception are active and are influenced by  underlying cognitive processes  Cognitive Processes: 1. Transformed: Our brain transforms all information into a neural code  2. Reduces: Our brain takes shortcuts (reduces information) 3. Elaborated: We then fill in missing information and integrate current information with  pre-existing information.   4. Stored, Recovered - Memory and Representing   5. Used: Language, decision making and problem solving In a nut shell:  What  We will cover:  Basic Neuroscience  Perception and Attention

Memory and Knowledge Representation  Language  Problem Solving and Decision Making  How Taking an information-processing approach  Information passes through a series of processing steps/stages  Typically assumes stages are specialized to carry out particular operations  Steps of Processing:  What are the stages? Basic components (that combine and interact to produce complex behavior) No universal agreement Boundaries may be fuzzy/nonagreement  Simple models of complex brains/behavior? Present some simplified stories Often the details get tricky If they weren’t, we probably wouldn’t be smart enough to be doing this anyway Used to simple accounts Now we can often see why they are wrong Not yet at the point of having the whole story Why study cognition? Intellectual curiosity Applications in Other Fields (e.g. economics, advertising, politics, system designs,  robotics, military, medical, educational)
