Underwater intelligibility of three standard word lists is evaluated in two experiments. Results indicate that words which are equated for difficulty in normal conditions are likewise equated under water. Phoneme distortion was examined in a multiple choice test which showed fricatives and place of production to be most affected under water. (SC)

Recent studies of folk biology clearly reveal the detailed empirical knowledge of living things which is an important and characteristic element of pre-scientific cultures. This paper attempts a contribution to the study of such systems of knowledge by analyzing the comparable skills of a few American birdwatchers. The process of identification of…

The categorizations which humans make of the concrete world are not arbitrary but highly determined. In taxonomies of concrete objects, there is one level of abstraction at which the most basic category cuts are made. Basic categories are those which carry the most information, possess the highest category cue validity, and are, thus, the most…

A report on a study to identify the relationship between subjects' age and their ability to imitate critical sounds of German. By having 210 American subjects repeat 20 critical German sounds in a non-critical context, a hierarchy of these sounds was established. Methodological conclusions are indicated. (AMH)

Reports a study determining whether significant differences in formant frequency are apparent when chronological age is compared with a measure of physiological age for children during the first six years. (TO)

Fourteen two-year-olds were presented with minimal word pairs in a new and efficient experimental perception paradigm. Data provide a view of relative difficulty of various minimal phonological contrasts for children. (CHK)

This article describes morphophonemic elements in Mazahua, a language of the Otomian family of Central Mexico. The study makes use of the theoretical and notational framework of generative phonology. (CLK)

A study of the phonetic combination of a constrictive consonant (specifically, [f], [v], and [r]) and a vowel in French using x-ray and oscillograph technology focused on the speed and process of articulation between the consonant and the vowel. The study considered aperture size, nasality, labiality, and accent. Articulation of a total of 407…

Ethnographic semantics is that discipline which seeks to understand human cognition through an analysis of the cognitive content of linguistic expressions: that is, the systematic study of the meanings of words and the role of these meanings in cognitive systems. There are many misconceptions about the nature of ethnosemantics, however, and by…

Patterns which partly resemble the proposed "fronting,""voicing," and "stopping" tendencies exist to a statistically significant degree in David Olmsted's large sample of child speech. Instead of the "voicing" pattern that has been suggested, however, voiced stops seem to be favored word-initially, but voiced fricatives are favored word-finally.…

Fricatives and affricates in different word positions and initial fricative clusters were elicited from three linguistically deviant children (ages five years, two months to seven years) and one normal child (age two years, nine months) by means of pictures depicting familiar objects. Data from two of the older children and the normal child are…

Thirty-five deaf children with hearing parents were tested for cheremic perception. Deaf children using sign language, like hearing children using spoken language, have more difficulty discriminating between lexical items that form minimal pairs in their language than between items that differ more.
