Describes a study that tried to answer the following: (1) Are the passives of all actional verbs equally easy to understand? (2) Are the passives of all experiential verbs in a child's vocabulary about equally hard to understand? (3) Does comprehension of passives differ from verb to verb in a category? (SED)

Describes a study of four- to five-year-old children's interpretations of statements involving "know" (savoir) and "think" (croire). The study tried to ascertain the language operations that modify a proposition or a basic assertion and to show the speaker's attitude towards the event asserted in the statement. (SED)

The use of the verbs "go" and "come" was examined in the spontaneous speech of seven two-year-olds. As verbs of motion, the words were used in the context of describing the contour of movement rather than as means of relating end-points of a journey. This is considered crucial in explaining children's difficulty in discriminating the verbs in…

The acquisition of Spanish as a first language was investigated in a study of eight Puerto Rican children ranging in age from 17-39 months. The speech of the four children studied in Puerto Rico was analyzed in detail and compared with that of the four children taped in Boston. The children's speech was taped in natural situations and analyzed in…

Spontaneous full passives and related constructions from 234 children, aged 2 to 13, and elicited passives from 262 college students were analyzed. The agentive non-reversible did not appear until after age 9; and until age 11 no child produced both reversible and non-reversible passives. (Author/SW)

A production-based method of investigating children's understanding of deictic verbs is described. Use of "come/go" and "bring/take" by 4-7-year-olds is compared with Clark and Garnica's 1974 study. Data reveal different facts about verb acquisition processes and order. (CHK)

Two experiments showed two-year-olds pairs of videotaped actions, one familiar and one novel, and asked them to select referents of novel verbs. For actions not involving objects, children tended to select the novel action over the familiar one in each of four experiments. For actions involving objects, novel actions were chosen more often than…

This is a quarterly report of a project involving the analysis of the language of four Puerto Rican children living in the Boston area who are learning Spanish as a first language. The children, all male, ranged in age from 17 months to 37 months during the period of study. All had some contact with English. The data were transcriptions of…

Preliminary version of this article presented at the meetings of the Society for Research in Child Development, Minneapolis, Minnesota, April 1971. Research and preparation of the paper supported in part by an Intramural Grant from the Regents of the University of California to T. Kenney. (VM)

This study aimed to determine the average ages at which children imitate, produce and comprehend passive constructions. Previous findings that imitation precedes comprehension, which precedes production, are confirmed in this study for children aged 3-8. (CHK)

A study was undertaken to test the theory that canonical sentence schemas can sometimes assign argument structure to verbs. The theory has the advantage of explaining errors without postulating the acquisition of erroneous lexical entries that have to be learned, and it can be extended to other kinds of errors in the choice and placement of…

Tested the cross-linguistic applicability of the dual mechanism model, investigating children's spontaneous performance with past definite and elicited performance with past definite and past participle. Performance profiles with productive and unproductive inflections could not be categorically distinguished. Phonologically transparent…

The progressive inflection "-ing" appears to be the earliest verb inflection acquired by children learning English as their first language. Explanations are made on why the progressive is rarely, if ever, overgeneralized to inappropriate forms. (SW)

Investigates the development of past tense expressions in the speech of children from 1.6 to 2.6. It is shown that this development depends crucially on the child's cognitive construction of the time dimension, as described by Piaget. (Author/RM)

The purpose of this paper is to examine the status of deictic reference in the speech of 19 three-year-old Black children. The deictic verbs of motion are examined with reference to other aspects of the deictic system. The data for this study are approximately eight hours of spontaneous speech collected in a pre-school classroom. The hypothesis to…
