Developmental Psychology Language Development Game Outline of Concepts in Game Phonemes Whole-Object Constraint Word / Naming Explosion Over-Extension & Under-Extension Pragmatics Developmental Theories of Language k h grobman - devpsy.org How the Game Works Your goal is to form a language. Since we only have a class period, your language will use a very limited world (i.e., shapes of varying size and color) and a very limited set of phonemes (i.e., 5). To illustrate your competence as using your language, one person should be able to describe a picture while another person produces it. Though this world is far less complicated then ours, communication is still complicated. Let’s try (in English). k h grobman - devpsy.org Your “World” k h grobman - devpsy.org Rules of the Game During the game, you can only speak with your groups’ phonemes. During “time-outs” you can speak English but you can not talk to your group-mates about the game. You can take notes (with English) to help reduce the working memory demands of the game. But do not show anybody what you wrote. At the end of class, we’ll have each group showcase their ability to communicate in the same way we just did with English. k h grobman - devpsy.org Your Phonemes Your group gets to use 5 phonemes. Each group has a unique set. Here’s a sample that does not match any actual group: ch u chair, beach, nature soon, through, boot affricate monophthong This means you get the sounds /ch/ and /u/. You do not get the sound /t/ even though a ‘t” is in bold. The words in the middle illustrate the use of the phoneme. The right column tells you the type of phoneme; it’s how your mouth, tongue, and vocal cords move. You can combine your phonemes in any way. For example, you might create a word that sounds like, “chooch.” k h grobman - devpsy.org What are Phonemes? Phonemes are basic units of sound in a language. Everybody says particular phonemes slightly differently, but when you say a different phoneme, you say a different word. (e.g, “ch” is a different phoneme from “th” as “chug” is different from “thug.”) k h grobman - devpsy.org Getting Ready to Play Pull out your lists of phonemes. Remember these are the only phonemes you can use in the game. Now pull out a single item from your world. When the game begins, say something using your language before you take anything else out of the envelope. k h grobman - devpsy.org Time In! Speak only with phonemes from your language and try to communicate about the objects in your world. The following chart helps you pace 45 minutes of game play, including all time-in and time-out portions. With the instructions before play and competition after play, the game can last one and one-half hours. Remember your row & column in the chart below for next time-in. The current time-in should last from: #:00 to #:07 #:20 to #:27 #:40 to #:47 #:05 to #:12 #:25 to #:32 #:45 to #:52 #:10 to #:17 #:30 to #:37 #:50 to #:57 #:15 to #:22 #:35 to #:42 #:55 to #:02 k h grobman - devpsy.org Whole Object Constraint One thing that facilitates children’s word learning is the biases (i.e., assumptions) they have when they hear new words. We will see several examples of this in our next class when we discuss fast mapping. Children behave according a whole object constraint. They assume that a novel word refers to the entire object we are paying attention to, rather than about a part or a quality of the object. Did you follow the whole object constraint within your group? k h grobman - devpsy.org Time In! Speak only with phonemes from your language and try to communicate about the objects in your world. The current time-in, from the same row and column as before, should last from: #:11 to #:18 #:31 to #:38 #:51 to #:57 #:16 to #:23 #:37 to #:43 #:56 to #:03 #:22 to #:28 #:41 to #:48 #:01 to #:08 #:27 to #:33 #:46 to #:53 #:06 to #:13 k h grobman - devpsy.org Language Explosion Between speaking our first words (about 12mo - 16mo) and starting to put together sentences (about 20mo 30mo), we go through a period where we acquire a vast number of words (15mo - 22mo). As children approach 2 years of age, they experience a language explosion. They learn about 10 to 20 new words each week. Most of those words are nouns. Did you experience a language explosion during the game? Were most of the words you created nouns? k h grobman - devpsy.org Time In! Speak only with phonemes from your language and try to communicate about the objects in your world. The current time-in, from the same row and column as before, should last from: #:22 to #:29 #:42 to #:49 #:02 to #:09 #:27 to #:34 #:47 to #:54 #:07 to #:14 #:32 to #:39 #:52 to #:59 #:12 to #:19 #:37 to #:44 #:57 to #:04 #:17 to #:24 k h grobman - devpsy.org Over-Extension & Under Extension An over-extension or under-extension of a word’s meaning, is a particularly common error for children as they learn new words. An over-extension is to use a word to refer to more than its intended referent. For example, a child may say “ball” to refer to balls, marbles, balloons, and eggs. An under-extension is to use a word to refer to less than its intended referent. For example, a child may only refer to her teddy-bear as “bear” rather than recognizing that everybody else’s teddy-bear and real bears are also “bears.” Were over-extensions or under-extensions a particular common error for you during the game? Or was another kind of error more common? k h grobman - devpsy.org Time In! Speak only with phonemes from your language and try to communicate about the objects in your world.

The spy sees the police officer with the binoculars. Who has the gun, the police officer or the spy?

Who has the gun, the police officer or the spy? Who has the binoculars, the police officer or the spy? k h grobman - devpsy.org Pragmatics The spy sees the police officer with the gun. The spy sees the police officer with the binoculars. Notice how the grammar of the two sentences is exactly the same. The ability to use background knowledge and context to understand language is called pragmatics. Like children, did you eventually develop pragmatics (in this game)? k h grobman - devpsy.org Time In!

Nativism: special innate abilities, that may include a language module, where acquiring language is different from other learning Interactionism: language is fundamentally a social experience Connectionism: Language is acquired through the regularities in our experience and exposure. Did you experience in today’s language game illustrate to you how one theory might be supported or refuted? k h grobman - devpsy.org Time to test your Language k h grobman - devpsy.org Testing your Language Development Divide your group into two sub-groups, talkers and listeners. The “listeners” get an envelope of the shapes. They should face away from the blackboard. The “talkers” face the blackboard and tell the “listeners” what to make, using their language. No group should look at what the others are doing. I’ll provide the drawing on the next slide. Then we will compare how close each group was to reproducing the picture. k h grobman - devpsy.org A Picture k h grobman - devpsy.org
