The patterns of silence: Performance structures in sentence production

The pauses produced by speakers while reading familiar material were used to obtain hierarchical sentence structures. Identical structures were obtained from parsing, indicating that the performance structures of sentences are not task specific. The linguistic surface structure of a sentence is a good predictor of the pause durations. However, speakers also revealed a tendency to place pauses between segments of equal length. A simple cyclical model combining, for each pause location, an index of linguistic complexity and a measure of the distance to the midpoint of the segment, accounts for 72% of the pause time variance as opposed to 56% for the linguistic index alone. The generality of the model is shown by its good prediction of the pause durations obtained in unrelated studies in English and American Sign Language.     

Study-time of sentences as a function of their specificity and of semantic exploration

In self-paced learning conditions the study-time of sentences is supposed to depend jointly upon the information content of the material and upon its exploration by the subject in the course of learning. In exp. 1 informative content was varied by using sentences constituted either of general or of specific words; study-time was found to be significantly longer for the latter sentences than for the former and the recall performance to be equal. Differential semantic exploration and storage were instigated by presenting in the series either pairs of similar, and thereby contrasted sentences, or isolated sentences. In exp. 2, study-time of the sentences was longer than that of the latter; but the first recall performance recorded with the constrasted sentences was also higher. The divergent effects of the nature of the material and of the activity of the subject upon study-time and recall performance were emphasized.     

The perception of rate in spoken and sign languages

The methods of magnitude production and estimation were used to scale the perception of signing rate by signers and observers. As in the case of voice level and speech rate, the autophonic scale of signing rate has a slope greater than unity and is steeper than the corresponding extraphonic scale; the obtained exponents of the two power functions for signing are, respectively, 2.66 and 1.56. When English-speaking subjects estimated their own rate of reading of the translated version of the signed passage, they produced an autophonic reading scale quite similar to that for signing (exponent of 2.51), but when they made magnitude estimations of English rates covering the same range of rates as the signed passage, the exponent of the extraphonic reading scale was significantly larger (1.89). This was also the case when French subjects estimated French reading rates. The difference between extraphonic signing and reading scales was confirmed by subjects who knew no Sign Language or French; their results appear to indicate, in addition, that the processes involved in extraphonic perception of rate are purely acoustic (speech) or visual (sign) and do not require, as one could have thought, deeper linguistic operations.     

Left hemisphere language lateralization in bilinguals and monolinguals

Tachistoscopic studies of lateralization in bilinguals suggest that there is a greater degree of right hemisphere involvement in their processing of language than is typically found in monolinguals. However, most of the studies reviewed failed to control the sex, handedness, and degree of fluency of the subjects and did not include a monolingual comparison group. The present study used adult right-handed males (Portuguese-English bilinguals and English-speaking monolinguals) in a tachistoscopic word-reading task. In Experiment 1, the words from the bilinguals’ two languages were presented in mixed blocks, while in Experiment 2, they were presented in separate blocks. The results were: (1) a similar level of left hemisphere advantage for language in the bilingual and the monolingual groups, (2) no evidence of greater heterogeneity of asymmetry patterns in bilinguals, and (3) a significant correlation (r=.61) for lateralization levels of the bilinguals’ two languages. These results indicate that language is processed primarily in the left hemisphere of both bilinguals and monolinguals.     

Spoken word recognition processes and the gating paradigm

Words varying in length (one, two, and three syllables) and in frequency (high and low) were presented to subjects in isolation, in a short context, and in a long context. Each word was presented repeatedly, and its presentation time (duration from the onset of the word) increased at each successive pass. After each pass, subjects were asked to write down the word being presented and to indicate how confident they were about each guess. In addition to replicating a frequency, a context, and a word-length effect, this “gating” paradigm allowed us to study more closely the narrowing-in process employed by listeners in the isolation and recognition of words: Some delay appears to exist between the moment a word is isolated from other word candidates and the moment it is recognized; word candidates differ in number and in type from one context to the other; and, like syntactic processing, word recognition is strewn with garden paths. The active direct access model proposed by Marslen-Wilson and Welsh is discussed in light of these findings.     

Detecting group differences in sequential association using sampled permutations: Log odds,kappa, and phi compared

When determining whether a particular transition is more characteristic of one group than of another, two things are required: an index associated with the transition of interest and a statistical test that can determine whether group membership systematically affects values for that index. Here the familiar parametrict test is compared with a test based on sampled permutations. Indices considered are the odds and log odds ratio, Yule’sQ, Wampold’s (1989) transformed kappa, and phi. The odds and log odds ratio are monotonically increasing functions of Yule’sQ and so give similar results. Yule’sQ and phi are essentially rank order invariant and usually give similar results. Transformed kappa, however, rank orders subjects somewhat differently than the others; moreover, it appears somewhat biased. With respect to the tests, when subjects are 20 or more it does not matter much whether sampled permutation or parametrict tests are used; both yield essentially the same result. However, when subjects are fewer than 20, or whenever there is any other reason to think that parametric assumptions may not be met, permutation tests are recommended. A computer program that effects such tests is described.     

A client-server technology solution for a multicenter research database

As researchers take advantage of advances in computer and related technologies, the amount of data has increased dramatically. Recent developments in database management systems (DBMS) such as client-server database technology provide the necessary tools for merging and managing data from various fields of study, as well as, various locations. This emerging technology allows the distribution of processing and data storage operations to a variety of computer plat-forms, thereby maximizing efficiency and flexibility. A DBMS that uses client-server technology is described.
