Chapter 7 Flashcards
Cognitive revolution
study of internal mental processes became an acceptable target for research
The alkinson-shiffrin (multi-store) model of memory
stimulus–> sensory organs–> sensory memory–> short term memory long term memory
During alkinson-shiffrin model of memory what occurs
info is rehearsed and some info is encoded into long term memory
Sensory organs
sense, eyes/ears, etc
Sensory memory
limitless, but short lived
Short term memory
lasts 30 seconds, working memory and rehearsal
Long term memory
unlimited, but not always accessible
Ionic memory
visual sensory store (no more than 1 second)
Echoic memory
auditory sensory store (no more than 5 seconds)
The whole report and condition
flashing letters at someone then asking them to report them back, can usually report 3-4 out of 12 letters
The partial report condition
hearing a tone while looking at letters to decided which row to repeat, people can report 3-4 out of 4
Attention
helps select a portion of the sensor memory for further processing
Change blindness
showwing someone a change in a picture, easier when presented simultaneously
Chunking
letters placed randomly vs connecting to larger units
The serial position effect
if given a long list of words, most likely to remember the first few and last few
First few words remembered =
primacy effect
Last few words remembered =
recency effect
2 types of forgetting
- proactive interference
- retroactive interference
Proactive interference
after hearing the first few words this makes it hard to remember other info
Retroactive interference
info presented later makes it hard to remember stuff from before
Phonological loop
for keeping sound based info active with rehearsal
The word length effect
easier to remember short words
Visuospatial sketchpad
for representing visual info and where objects are in space (traffic flow)
Feature binding
seeing something as whole rather than a collection of features
Episodic buffer
for representing combined auditory, visual, and knowledge from long term memory store
Central executive
for coordinating the functions of the 3 storage systems and directing attention to sensory inputs
Declarative memory
memories that involve our conscious minds and that we can we can describe verbally
Non-Declarative (implicit) memory
memory for previously learned s``kills and associations that guide our thoughts, feelings snd actions automatically and unconsciously
Non-declarative memory includes…
includes all of the unconscious influences of memory
Types of declarative memory
- episodic memory
- semantic memory
