Unformatted text preview: Cognitive Psychology I- Memory: The Big Picture Memory as information processing: stages and events of memory Effortful memory o All that was studied for about 100 years, one of oldest topics, easy to study o People given a list to remember and come back a week later to recite o When we are trying to learn and remember Memory without awareness o Begun to be understood in last 15 years o When we remember things we dont realize weve remembered o Part of a general trend when conscious thought was given priority for 30, 40 years The fragility of memory o Our memories are often a distorted view of reality o Much more susceptible to distortion, bias, error than we think Stages of Memory The different timings of memory Sensory memory: happens in typically less than a second, the immediate and initial recording of sensory info in the memory system o External events sensory memory short-term memory long-term memory o Registers incoming info, allowing your brain to capture for a fleeting moment lots of faces o Attention to important or novel info: encoding o Put into short-term memory: activated memory that holds a few items briefly before the info is stored or forgotten o Long term memory: relatively permanent and limitless storehouse of the memory system Process of encoding, storage and retrieval We can have problems when we dont remember things o Info may not have been encoded properly o Could have trouble remembering info if it has gotten lost in storage o Can have trouble retrieving info but you know its not lost Effortful Memory How much information do we retain? How long do you retain info in short term memory?
