1 Learning and Remembering

2 Objectives Sensory, short-term, and long-term memory
Two kinds of long-term memory Event-related activity in the brain Theories of forgetting

3 Basic Concepts and Definitions in Memory
Attention, memory, and learning Early Studies of Exceptional Memories S who had an astounding memory Memory curves

4 Defining Memory Memory Remembering and Knowing Forgetting
Availability of information Ability to retrieve previously acquired skills or information Remembering and Knowing The trees with their growth rings know things, but they remember nothing Storage and retrieval Forgetting The other side of learning Inability to retrieve or an actual change in the physiological effects of experience

5 Early Memory Research Retroactive interference Proactive interference

6 Three-Component Model of Memory
Short-term memory Long-term memory Sensory memory

7 Sensory Memory Term for the immediate, unconscious effects of stimuli
Cocktail party experiments

8 Short-Term (or Working) Memory
A classical study of STM Function of rehearsal and time lapse Limited Capacity Working memory: concious at any given time Seven slots plus or minus two

9 Short-Term (or Working) Memory
Chunking Short term memory slots don’t have to be unitary Baddeley’s model of working memory Central executive system Slave systems: phonological loop and visual-spatial sketch pad

10 Short-Term (or Working) Memory
Decay theory Memory traces vanish quickly with the passage of time Displacement theory There are a limited number of slots and incoming information displaces old information Interference theory Previous learning (rather than subsequent information) might somehow interfere with short-term memory Levels of Processing Main difference between short- and long-term involves how input is processed

11 Long-Term Memory Long-term memory is highly stable
Long-term memory is generative Schemata or scripts influence memories It makes people to remember things that have never happened (generation rather than reproduction)

12 Long-Term Memory Understanding influences long-term memory
Some things are more easily remembered Flashbulb memories

13 Short-Term and Long-Term Memory Compared
