Language
The communication of information through symbols arranged according to rules. Language is central to communication, and closely tied to the way we think about the world. It develops in the absence of formal instruction and follows similar patterns cross culturally.
Phenomes
The smallest categorie of sound our vocal apparatus produces. Different languages use different number of phenomes.
Morphemes
The smallest unit of meaning in a language. Most morphemes are also words, or modify the meaning of other words.
Syntax
The set of rules of a language by which we construct a sentence.
Critical Period
Proficiency at acquiring language is maximal early in life. Being deprived of language during the critical period impedes the ability to fully acquire and use language.
Language Development stages
1-2 Months - Cooing
4-10 months - Babbling
6-8 months - specializing in own language while babbling
8-16 months - Single word stage
24 months - two word stage
Telegraphic Speech
3 years - plurals and past tense, but overgeneralized.
Age 5 - All basic rules.
Learning-theory approaches
The theory for language acquisition that involves following principles of reinforcement and conditioning. It believes that the more parents speak to children the more proficient they are. Children are praised for using language, but this theory doesn’t really explain language rules (correct grammar, etc.). (Skinner)
Interactionist
The learning acquisition theory that believes that we are pre-programmed with the hardware for learning, but develop the software through exposure and environment. Looks at adults as directors for language acquisition, but not pure imitation. Environment produces differences in language.
Nativist
The language aquisition theory that believes children are born with all the basic knowledge of language that they need. We have a “language organ” or language acquisition device that is pre-programmed with the info we need. Difficult to falsify. Noam Chomsky
Linguistic Relativity (Sapir-Whorf Hypothesis)
The theory that the language we speak influences how we think, understand, and perceive the world. Includes egocentric vs geocentric, time perception & metaphors, language & blame.
Thinking
The manipulation of mental representations of information.
Top-Down Processes
Streamlines cognitive functioning by utilizing pre-existing knowledge to fill in the gaps. Speeds up cognitive processing and helps to reduce complexity of new experiences.
Prototypes
Best or most typical example of a concept
Concept
Our knowledge and ideas about a set of objects, actions, and characteristics that share core properties.
Mental Set
Becoming stuck in a specific problem-solving strategy, inhibiting our ability to generate alternatives.
Functional Fixedness
Difficulty conceptualizing that an object typically used for one purpose can be used for another.
Algorithm
A rule that, if applied properly, guarentees a solution to the problem. It only works well for well-defined problems and is often time consuming
Heuristic
A general problem-solving framework (shortcuts, rules of thumb). Can involve lots of cognitive biases and obstacles. It reduces mental effort and simplifies the decision-making process.
Representativeness heuristic
Basing judgements on similarity to an abstract ideal, expectation, or stereotype.
Base-rate Fallacy
Base rates aren’t sufficiently taken into account.
Availability Heuristic
Basing estimates of frequency or probability on the ease of which examples come to mind.
Anchoring Heuristic
Relying on a single piece of information to inform decision -making.
Framing
The way a question/statement is formulated can influence decision-making (gain vs loss, survival vs. mortality framing).
Hindsight bias
Our tendency to overestimate how well we could have predicted something after it has already occured.
