Sensory memory (1 second or less) results from our perceptions automatically. It includes two sub-systems: iconic memory of visual perceptions echoic memory of auditory perceptions. PRIMARY MEMORY (20 – 30 minutes in duration) Frontal cortex Short Term Memory (< 2 seconds) 7+ 2 items of a list Working Memory (20 – 30 min.) SECONDARY MEMORY (Years – Decades) Hippocampus Long Term Memory Baddeley’s model of working memory This model posits a central processor that coordinates the activity of two sub-systems. high activity in the frontal lobe when this central processor is working. Baddeley’s model also postulates the existence of: a phonological (acoustic and linguistic) memory - activates certain areas in the left hemisphere that are associated with the production of language, such as Wernicke’s area and Broca’s area. a visual/spatial memory (containing mental images) - associated with a region of the occipital cortex generally associated with visual

Unformatted text preview: processing Long Term Memory 1.) Episodic memory The hippocampus, the cortical structures surrounding it, and the neural pathways that connect them to the cortex as a whole are all heavily involved in declarative memory –the memory of facts and events. Facts are distributed in the various visual, olfactory, and auditory areas of the brain, but they are all connected together by the hippocampus to form an "episode", rather than remaining a collection of separate memories. episodic memory 2.) Semantic memory - activates the frontal and temporal cortexes 3.) Spatial memory- confined to the right hippocampus. 4.) Emotional Memory - the amygdala, which is already known to manage our reactions to fear 5.) Procedural memory , - knowing how to ride a bike - associated with all of which are involved in motor control. • the cerebellum, • the basal ganglia, and • the motor cortex,...
