  1. Class Exercises MLU and Morphology

  2. ed (past) ex (out of, from) mis (negative, wrong) out (extra , beyond) over (too much) post(behind) al (pertaining) en (used to form verbs from adjectives) ism (doctrine, state) ist (one who does something) ity (used for abstract nouns) lv (used to form adverbs) ing (at present) ‘s (possession) bi (twice) semi (half) super (superior) trans (across) tri (three) un (not) under de (reversal) pre (before) pro (in favor of) re (again) able (ability) ize (action, policy) less (without) ly( used to form adverb) s (plural) • ness (quality) • er, or (used as agentive • ending) • ous ( full) • y (inclined to) • ance ( action, state) • est (superlative) • ful (full, tending) • ible (likelihood) • ish (belonging to) • s (third person marker)

  3. Suffixes Derivational Inflectional Prefixes

  4. Exclude from your count Imitations Elliptical answers Partial utterances Unintelligible utterances Rote passages False starts and Reformulations within utterances Noises Discourse markers Identical utterances Counting or other sequences of enumeration Single words or phrases Calculating MLU Do’s and don’ts • Count as one morpheme • Uninflected lexical morphemes • Contractions • Concatenatives • Inseparable linguistic units • Irregular past tense • Plurals which do not occur in singular form • Gerunds and participles that are not part of the verb phrase • Inflectional forms • Contractions • You need at least 50 utterances to calculate MLU • 100 is recommended Lund and Dunchan (1993)

  5. Calculating MLU • After you have counted all the morphemes, you are ready to calculate the MLU. The traditional method of calculating MLU is dividing the number of morphemes by the number of utterances. For example: 150 morphemes / 50 utterances = 3.0 MLU

  6. Sample 1 1) Calculate MLU 2) which of Brown’s developmental stages has the child reached? 3) identify the morphemes used by the child 4) identify the semantic functions used by the child

  7. *CHI: why dis got holes? %act: looking at holes in Ursula's pad *URS: so you can put it in a notebook # if you like. *CHI: 0. %act: falls from bike *URS: what happened? *CHI: I fall # broke my head. *URS: you didn't. *CHI: tell me story. *CHI: tell me story. *URS: shall we look at these first? %act: gives Adam bag of toys *CHI: let's open it. *CHI: what is it? *URS: it's a watch. *CHI: dat's a watch. *CHI: fourteen clock. *URS: what is it? *CHI: fourteen o'clock. *CHI: stop it. *URS: what? *CHI: stop it. *CHI: turn back on. *CHI: has wings. *URS: where? *CHI: turn it. *CHI: stop it. *CHI: it's fourteen clock. *CHI: enough clock. *CHI: in go clock. %act: putting watch away *CHI: a tape recorder. *CHI: where is a box? %act: <aft> taking watch out again *CHI: it's fourteen clock. *CHI: it not fourteen clock # it nineteen # six # how d(o) you know? *CHI: it's not six # it number two. *CHI: how d(o) you know it going eat supper? %exp: presumably the watch *CHI: how (a)bout eat supper? *CHI: it's fourteen o'clock. *CHI: well # well. *CHI: it's fourteen cl(ock) # clock. *CHI: achoo@o. *CHI: le(t) me stop it. *CHI: le(t) me turn on. *CHI: xxx put in. *CHI: put in. %act: puts watch back in box *CHI: it's go to sleep.

  8. Stage Age ( years) MLU I 1-2:2 1:0-2:0 II 2:3-2:6 2:0-2:5 III 2:7-2:10 2:5-3:0 IV 2:11-3:4 3:0-3.75 V 3:5-3:10 3:75-4:5

  9. Semantic Roles

  10. Possessives daddy coffee Andrew shoe Property-indicators big balloon little shell all wet ball all wet pants dirty face old cookie Recurrence / number / disappearance more glass two plane all gone bee window bye-bye Locatives ball daddy (TO) stick car (IN) Actor/Action mommy sit daddy work Andrew sleep Others eat dessert bounce ball Two-word utterances

  11. Semantic Relations in 1-word stage • POSSESSION “Daddy” (=slippers) • IMPERATIVE “open” = open the jar “blow” = blow my nose • NEGATIVE “no” = negate actions • LOCATION “down” = getting down from high chair • RECURRENCE “more” • DISAPPEARANCE “allgone”
