Linguistic cues in the acquisition of number words.

Previous research has shown that children go through a stage in which they know that the number words each refer to a distinct numerosity, yet do not know WHICH numerosity each number word picks out (Wynn, 1992). How do children attain this level of knowledge? We explore the possibility that particular properties of how number words are used within sentences inform children of the semantic class to which they belong. An analysis of transcripts of the spontaneous speech of three one- and two-year-old children and their parents (from the CHILDES database; MacWhinney & Snow, 1990) suggests that the relevant cues are available as input in parents' speech to children, and that children generally honour these properties of number words in their own speech. Implications of this proposal for word learning more generally are discussed.

Cognitive and linguistic correlates of children's discourse after closed head injury: a three-year follow-up.

The discourse of 91 children who had sustained severe (n = 68) or mild (n = 23) closed head injury (CHI) was examined at least three years postinjury. The groups' retellings of a narrative story were analyzed according to two domains, information and language. In comparison to the mild CHI group, the severe group produced stories characterized by reduced content and information, impaired organization, fewer words, and less complex sentences. The relationships between discourse production and the groups' performance on measures of language, executive function, memory, and processing speed were examined. Correlations were found between discourse production and general verbal ability including verbal fluency. Correlations were also found for discourse performance and executive function measures associated with problem solving and working memory. Site and extent of lesion were not useful in predicting discourse production. These findings indicate that children who sustain a severe closed head injury during early to middle childhood are at risk for persisting deficits in discourse processing and other cognitive abilities.

Counterintuitive cross-linguistic differences: More morphological computation in English than in Finnish.

This study investigates the role of derivational morphology in lexical processing in two typologically quite different languages: Finnish and English. While Finnish is a language with an extremely rich morphology, English morphology is relatively poor. Consequently, the role of morphology in storing and processing words would be expected to be greater in Finnish than in English. With a series of visual lexical decision experiments in both languages, we find that the opposite is the case for derivational morphology: for English, parsing of morphological constituents is often required, whereas for Finnish, full-form storage and access seems to be the rule. We try to explain this counterintuitive finding by making an appeal to the lexical-statistical properties of both languages.

Integration of syntactic and semantic information in predictive processing: cross-linguistic evidence from German and English.

Two visual-world eyetracking experiments were conducted to investigate whether, how, and when syntactic and semantic constraints are integrated and used to predict properties of subsequent input. Experiment 1 contrasted auditory German constructions such as, "The hare-nominative eats ... (the cabbage-acc)" versus "The hare-accusative eats ... (the fox-nom)," presented with a picture containing a hare, fox, cabbage, and distractor. We found that the probabilities of the eye movements to the cabbage and fox before the onset of NP2 were modulated by the case-marking of NP1, indicating that the case-marking (syntactic) information and verbs' semantic constraints are integrated rapidly enough to predict the most plausible NP2 in the scene. Using English versions of the some stimuli in active/passive voice (Experiment 2), we replicated the same effect, but at a slightly earlier position in the sentence. We discuss the discrepancies in the two Germanic languages in terms of the ease of integrating information across, or within, constituents.

The acquisition of temporal reference cross-linguistically using two acting-out comprehension tasks.

The acquisition of temporal event referencing, encoded by the temporal connectives: then, before, after, when, while, together, until, and since in English, Thai and Lisu was investigated using two acting-out comprehension tasks, a Marble task and a Toy task. Forty children aged 3.6-7.6 years from each language participated. The Marble and Toy tasks differed in their cognitive complexity: in the Marble task the child had to act out only one clause, whereas in the Toy task the child had to act out both clauses. This task manipulation affected performance in Lisu children only. Language-general effects were found, namely "then" and "together" were relatively early and "since" was relatively late in acquisition. Language-specific effects were found for Thai and Lisu. Results confirm that characteristics of task and test sentences affect children's comprehension of sentences expressing temporal relations and can partially account for the disparity in acquisition order found in previous studies.

Comprehending idioms cross-linguistically.

Speakers of three different languages (English, Latvian, and Mandarin) rated sets of idioms from their language for the analyzability of the relationship between each phrase's literal and figurative meaning. For each language, subsets of idioms were selected based on these ratings. Latvian and Mandarin idioms were literally translated into English. Across three experiments, people classified idioms from the three languages according to their figurative meanings. Response times and error rates indicate that participants were able to interpret unfamiliar (e.g., other languages') idioms depending largely on the degree to which they were analyzable, and that different forms of processing were used both within and between languages depending on this analyzability. Results support arguments for a continuum of analyzability (Bortfeld & McGlone, 2001), along which figurative speech ranges from reflecting general conceptual structures to specific cultural and historical references.

Linguistic and conceptual influences on adjective acquisition in 24- and 36-month-olds.

Two hundred forty English-speaking toddlers (24- and 36-month-olds) heard novel adjectives applied to familiar objects (Experiment 1) and novel objects (Experiment 2). Children were successful in mapping adjectives to target properties only when information provided by the noun, in conjunction with participants' knowledge of the objects, provided coherent category information: when basic-level nouns or superordinate-level nouns were used with familiar objects, when novel basic-level nouns were used with novel objects, and--for 36-month-olds--when the nouns were underspecified with respect to category (thing or one) but participants could nonetheless infer a category from pragmatic and conceptual knowledge. These results provide evidence concerning how nouns influence adjective learning, and they support the notion that toddlers consider pragmatic factors when learning new words.

Linguistic signatures of regulatory focus: how abstraction fits promotion more than prevention.

In 3 experiments, the authors investigated how strategic inclinations associated with promotion versus prevention orientations--that is, eager approach versus vigilant avoidance, respectively--affect the use of language. It is hypothesized that eager promotion strategies used to attain desired end states entail using more abstract language than used with vigilant prevention strategies. This is shown to hold for experimentally induced relationship goals (Experiment 1) and communication goals (Experiment 2). In the 3rd experiment, the authors examined the impact of abstractly and concretely worded messages upon the behavioral intentions of chronically prevention- and promotion-oriented individuals and found support for the hypothesis that behavioral intentions to engage in specific activities are stronger when there is a fit between message wording and chronic orientation than when there is no fit. The broader implications of these findings are discussed.

Do verbs and adjectives play different roles in different cultures? A cross-linguistic analysis of person representation.

Five studies are reported testing the hypothesis that Westerners (Italians) rely more on trait adjectives and that East Asians (Japanese) rely more on behavior-descriptive verbs in person description and memory. In Studies 1 (N = 80) and 2 (N = 128), Italians used more adjectives and fewer verbs than Japanese to describe individuals and groups. Likewise, Studies 3 (N = 161) and 4 (N = 84) revealed that Italians committed more memory errors indicative of behavior-to-trait inferences, whereas Japanese showed an opposite tendency (Study 3) or no difference (Study 4). Study 5 (N = 64) revealed that in both languages, adjectives were perceived to provide more information about the actor and that verbs were perceived to provide more information about the situation. Yet, Japanese participants found adjectives less predictive of future behavior but facilitative of the process of imagining a concrete situation. These results are interpreted as providing evidence for systematic cultural differences in the elaboration of social information.

Orthography and the hemispheres: visual and linguistic aspects of letter processing.

Hebrew and Arabic are Semitic languages with a similar morphological structure and orthographies that differ in visual complexity. Two experiments explored the interaction of the characteristics of orthography and hemispheric abilities on lateralized versions of a letter-matching task (Experiment 1) and a global-local task (Experiment 2). In Experiment 1, native Hebrew readers and native Arabic readers fluent in Hebrew matched letters in the 2 orthographies. The results support the hypothesis that Arabic orthography is more difficult than Hebrew orthography for participants who can read both languages and that this difficulty has its strongest effects in the left visual field. In Experiment 2, native Arabic speakers performed a global-local letter detection task with Arabic letters with 2 types of inconsistent stimuli: different and similar. The results support the hypothesis that the right hemisphere of skilled Arabic readers cannot distinguish between similar Arabic letters, whereas the left hemisphere can.
