Unformatted text preview: PSY Ch. 5 Memory Origins of memory research Ebbinghaus developed lists of three letter combos (not words) and learned the list to perfection some days later he would see how long it took him to relearn the list to perfection. There was an immediate drop off, but then it leveled off with only slight decline. Stroop Effect three columns (experiment in class, red ink on the word blue) I. The Three-Stage Model of Memory a. Has guided much research since the late 1960s b. In general, flows from the physical environment through our senses into sensory memory short term memory long term memory short term memory again, when we need to recall it II. Stage One: Sensory Memory a. SM consists of a set of registers where we temporarily store incoming sensory information from the physical environment until we can attend to it, interpret it, and move on to the next stage important to note that this information has not yet been recognized, because once we are aware of it, it has moved into short- term memory b. Vision is our dominant sense, and creates iconic memory i. Iconic memory is a photographic memory but for less than 1 sec. c. Temporal integration procedure i. Heres how it works: two random meaningless dot patterns are presented sequentially at the same visual location with a brief delay between them. When these two meaningless patterns are integrated, a meaningful pattern is produced; if the meaningful pattern is registered, this means that the two patterns must have been integrated into our memory system. (think of the VOH) ii. Even if the pattern is made much more complex, people can see it; therefore, the capacity of iconic memory is large but its duration is very brief, less than 1 second. d. Sperlings full- and partial-report procedures i. Heres how it works: On each trial, participants were presented with a different matrix of unrelated consonants for 50 msec and tasked to report the letters in the matrix briefly flashed on each trial ii. Sterling used two different report procedures 1. In Sperlings full-report procedure participants had to try to report the entire matrix of letters (they got 4.5 letters on average, usu. In the top and left second row; they also reported that they sensed the rest of the model but that it had faded from memory) 2. In the partial-report procedure, the participants had only to report a small part of the presented letter matrix, indicated by an auditory cue immediately following (high pitch learn top row and so on); participants recalled the correct row 100% of the time, so...
