Chapter 8-thinking, reasoning, & language Flashcards
Define thinking
Any mental activity or processing of information. Includes learning, remembering, perceiving, communicating, believing and deciding
What are benefits to cognitive economy
Allows us to simplify what we attend to and keep the information we need for decision-making to a manageable minimum because we have limited processing resources and cannot process everything
-allows us to block the processing of some inputs from other inputs
What is the meaning of thin slicing
Our ability to extract useful information from small bits of behaviour
Define a base rate
Based rate is a fancy term for how common a behaviour or characteristic is in general
What is a representativeness heuristic?
heuristic that involves judging the probability of an event based on how prevalent that event has been in past experience
What is the availability heuristic
We estimate the likelihood of an occurrence based on how easily it comes to our minds, or how “available” it is in our memories
Define hindsight bias
Refers to our tendency to overestimate how accurately we could have predicted something happening once we know the outcome.
“I knew it all along”
What are concepts? Schemes?
-Concepts are our knowledge and ideas about objects, actions, and characteristics that share core properties.
-schemas are concepts we’ve stored in memory about how certain actions, objects, and ideas relate to each other.
(Common sources of top-down processing)
Define decision making
The process of selecting among a set of alternatives
Define problem-solving
Generating a cognitive strategy to accomplish a goal
Define algorithms
Step-by-step learned procedures used to solve a problem. (Come in handy for problems that depend on the same basic steps for arriving at a solution every time the solution is required)
Define framing
The way a question is formulated that can influence the decisions people make
What is a mental set
Phenomenon of becoming stuck in a specific familiar problem-solving strategy, inhibiting our ability to generate alternatives
Defined language
A system of communication that combine symbols, such as words or gestural signs, in rule-based ways to create meaning
We can think about language at four levels of analysis, all of which we need to coordinate to communicate efficiently. Name these levels of analysis
A. Phonemes
B. Morphemes
C. Syntax
D. Extralinguistic information
Define phonemes
Category of sounds our vocal apparatus produces
-influenced by elements of our vocal track, including our lips, teeth, tongue placement, vibration of vocal chords, opening and closing of our throat and more
Ex. Sh, ch, p
-babies initially sensitive to all phonemes o(therefore easier to learn languages at young age)
Define morphemes
Smallest unit of meaningful speech/language
- created by stringing phonemes together
- most morphemes are words such as Dog and happy
- we also have strings of sounds that aren’t words by themselves but modify the meaning of words when their tacked onto them (ex. Ish or Re) they don’t stand alone as words
Define semantics
Meaning derived from words and sentences
- morphemes convey information about semantics
Define syntax
- syntax is a set of grammatical rules of language by which we construct meaningful sentences
- includes morphological markers (ing, ed, s)
- Real world language rarely follows them perfectly
Define extralinguistic’s
Elements of communication that aren’t part of the content of language but are critical to interpreting its meaning
-nonverbal cues such as facial expressions, tone of voice posture, gestures
