What is Memory? “Memory is the storage of an internal representation of knowledge” Blakemore (1988) http://www.youtube.com/watch?v=PzvkUkobFdg&mode=related&search= Memento Trailer Cognitive Psychology
Some memory experiments • Ethics briefing • These experiments look at how we memorise information • Each experiment will last less than 5 minutes • All results are confidential • You do not have to participate • You may withdraw at any time • There will be no long-term effects Cognitive Psychology
First Experiment Instructions • Write the letters A, B, C & D down the side of your page • Pens down! • You’ll be given 10secs to memorise each number that appears • When it disappears I’ll give an instruction to pick up your pen • Using your memory try to write down the number you just saw Cognitive Psychology

In a moment this grid will be full of letters. Try to remember as many of these letters as you can, in their correct position, in a 2 minute time period. Cognitive Psychology

Capacity of short-term memory Discussion questions • Experiment 1: At what point did you begin to find it difficult to recall the numbers in the correct order? • Experiment 2: How many letters did you recall correctly in the grid? • What techniques did you use for remembering? • What does this tell us about capacity of short-term (immediate) memory? • How can we use this knowledge in everyday life? Cognitive Psychology
The Memory Decay Curve • Ebbinghaus learnt lots of meaningless lists • He found that once learnt they quickly decayed • Although re-learning was quicker than learning from scratch Cognitive Psychology
Enduring Long Term Memories • People were asked about high school year books • Had to identify old classmates • People seem quite good at this Bahrick et. al. 1975 Cognitive Psychology
Recall of an Early Memory • We forget a lot before the age of 4 • When people were asked questions about the birth of a younger sibling the older children could recall more (Sheingold & Tenney 1982) Cognitive Psychology

Working Memory Cognitive Psychology
Features of Working Memory • There are two components linked to Central Executive • 1.Articulatory or phonological (speech-sounds) • 2. Visual-spatial (vision-images) Cognitive Psychology
Testing Working Memory • There are two assumptions to this model • 1.If two tasks make use of the same component, they can not be performed successfully together. • 2. If two tasks make use of different components it should be possible to perform them as well together as separately. Cognitive Psychology
B is before A BA G is before H GD N is after J JN F follows W WF P is before Y YP S follows Q SQ Baddeley & Hitch (1974) Participants had to say whether the following was either true or false. Cognitive Psychology
Baddeley & Hitch (1974) • While working out these problems, participants had to do one of the following: • Say “the” repeatedly • Repeat the sequence “one, two, three, four, five, six” over and over • Repeat a different random run of digits each time • Do nothing – just the task Cognitive Psychology

Craik & Tulving (1975) • table • Is the word in capital letters? • HOUSE • Does the word rhyme with mouse? • Fence • Does the word fit with the following statement; • The man fixed the ____ because the wind blew it over They did an experiment similar to the previous one. Although they used slightly different processes They also did not tell people that they would be expected to recall the words Cognitive Psychology
