Quiz 1 (lesson 2) Flashcards
What is memory?
the faculty of the brain by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action
What is short term memory?
Short term memory is a temporary store. Some things from it end up becoming long term memories. STM holds things you are actively thinking about
What is sensory memory?
Like a sketch pad(for vision) or a bit of recording tape(for hearing) that can be overwritten with new things. Processes info gathered through the five senses
How long does sensory memory hold things?
It is rewritten every few seconds by new perceptions
What is long term memory?
Things in long term memory are probably stored here forever. However we might have trouble with retrieving it
How long does short term memory hold things?
Things stay in STM for an estimated 2 days to 20 years
What is working memory?
Stuff you pull out of the filing cabinet of long term memory for use
What is explicit memory?
Declarative memory, or explicit memory, consists of facts and events that can be explicitly stored and consciously recalled or “declared.”. Ex. Justin trudeau is the prime minister of Canada
What are the two types of explicit memory?
Semantic and Episodic memory
What is semantic memory?
Semantic memory is a type of long-term memory involving the capacity to recall words, concepts, or numbers, which is essential for the use and understanding of language. General knowledge of the world & Facts
What is episodic memory?
Episodic memory is the memory of everyday events that can be explicitly stated or conjured. It is the collection of past personal experiences that occurred at particular times and places; for example, the party on one’s 7th birthday. Where someone parked their car
What is implicit knowledge?
Implicit knowledge is knowledge that is difficult to transfer to another person by means of writing it down or verbalizing it. ex what an iphone looks like
What is procedural knowledge?
Procedural knowledge is the knowledge exercised in the performance of some task. Ex. how to tie a shoe. Can do but might not be able to explain (type of implicit knowledge)
Why do old people have trouble remembering things?
Old people have trouble with remembering things because there’s so much stuff in their long term memory that they get interference
What is a cognitive system?
a system capable of cognition
What is a system?
a set of things working together as parts of a mechanism or an interconnecting network
What is cognition?
There’s no one answer to what cognition is, it’s a definitional answer. In this class we say that cognition is the manipulation of representations
What are representations?
Something that is used in place of the real thing. Sometimes there’s not even a real thing
What is distributed cognition?
Distributed among several things. No one person/entity has all the information. Like the brain where there’s a bunch of different parts that all serve different functions(although that doesn’t mean that its distributed cognition or else everything would be. Ex. a person constructing a house writes where stuff is supposed to go using a blueprint. Note its not using a tool(using a map to get around somewhere is not distributed cognition)(understanding vs using). Both things should be interacting with each other
What is disembodied software?
Software running somewhere but the body doesn’t matter(probably in a server room). Ex. Amazon’s recommendation system. Perceives user input and updates its database. Then displays something to the user’s screen based on its database
What are (cognitive) artifacts?
Man-made things that seem to aid or enhance our cognitive abilities. Some examples are calendars, calculators, whiteboards, to-do lists, computers, or simply tying a string around your finger as a reminder
What do robots use to perceive things?
Sensors
What do robots use to do actions?
Actuators
What do animals use to perceive things?
Senses
