Reading Gerrig et al.  (Chapter 8): Cognitive processes
The Brain:  1.5 kg of wet tissue
Cognitive Scenarios:  A mysterious note At midnight, there's a knock on your door. When you answer, there is no one there, but you see an envelope on the floor. Inside the envelope is a handwritten message: “The cat is on the mat.” What do you make of this? Gerrig et al. (2008), p. 248
Cognitive Scenarios:  Attention, Problem Solving, Memory... Kris is sitting at a desk reading some interesting papers to help with an assignment. Without removing her eyes from the paper she is reading, she reaches for a bag of sweets, unties a wrapper and pops a sweet into her mouth. Suddenly she stops and wonders: “What is happening here?” Gerrig et al. (2008), p. 248

Language understanding
Language & evolution
Linguistic relativity
Visual representations
What people say, sign, and write and the processes they go through to produce the message  Speakers versus listeners Language production
Shaping a message depending on the audience H. Paul Grice
Cooperative principle Speakers should produce utterances appropriate to the setting and meaning of the ongoing conversation Audience design

Representations Speech execution  & speech errors
Resolving ambiguity Lexical ambiguity

Propositions Language understanding
Fully human speech anatomy first appears in the fossil record ~50,000 years ago. Language & evolution May have evolved with walking, running, tool making, & complex group organisation.

Language development Babbling stage : 4 months, sounds like “ah-goo”
One-word stage : ~1 year old.
Telegraphic speech : Before 2nd birthday, “want juice”
Complete sentences : 2+ years
Language development We learn language before learning numbers
Between 1 and 18, we learn on ~10 words/day or 3,500 per year.

Language development Operant Learning (Skinner)  -  language development can be explained on the basis of learning principles such as association, imitation, and reinforcement.
Inborn Universal Grammar (Chomsky)  -  the rate of language acquisition is so fast that it cannot be explained through learning principles, so most of it is inborn.
Phonemes The smallest, distinctive sound unit
bat, has three phonemes b · a · t
chat, has three phonemes ch · a · t
Morpheme Smallest unit of language that conveys meaning Bat
Pre
Un
Undesirables –  4 morphemes Un-desir-able-s
Grammar - the rules Semantics  – how we get meaning from the sentence, e.g., add “ed” and it happened in the past Syntax  – rules for making a grammatically correct sentence http://en.wikipedia.org/wiki/Mr._Ed
Semantics & syntax They are hunting dogs.
They are  hunting  dogs.
They are hunting  dogs .

The availability heuristic is a phenomenon (which can result in a cognitive bias) in which people predict the frequency of an event, or a proportion within a population, based on how easily an example can be brought to mind.
