Visually perceiving distance: a comment on Shebilske, Karmiohl, and Proffitt (1983).

Shebilske, Karmiohl, and Proffitt (1983) interpret their data as showing that (a) the reference tonus level of the extraocular muscles controlling vergence is affected by everyday conditions of close viewing, and (b) this naturally induced phoria affects the visual perception of distance under natural viewing conditions. We note that these interpretations do not fully concur with the data presented--for example, the second conclusion favorably conflates partial results from two separate experiments--and we identify a number of confoundings that reduce the likelihood that the reported inaccuracies in distance judgments were due to variations in efference.

Word recognition in Serbo-Croatian is phonologically analytic.

A lexical-decision task was conducted with bialphabetic readers of Serbo-Croatian. It was shown that letter strings that can be assigned both a Roman and a Cyrillic alphabet reading incur longer latencies than does the unique alphabet transcription of the same word. This within-word phonological-ambiguity effect was obtained for both words and pseudowords, but the effect was more exaggerated with words. In addition, the magnitude of the difference depended on the number and distribution of ambiguous characters in the ambiguous letter string. It was concluded that lexical decision in Serbo-Croatian necessarily involves a phonologically analytic strategy.

Immediate compensation in bite-block speech.

An experiment was conducted to examine whether a bite block affects the latency and/or the quality of spoken vowels. The results suggest that vowels spoken with the bite block and vowels spoken normally were (1) of the same latency, that is, the same time elapsed between visual presentation and initiation of response; and (2) of the same quality, and that is, the acoustic measures of the vowels did not differ substantially. Moreover, there was minimal evidence of improvement in either latency or quality with practice, and minimal evidence of an effect of time pressure on the quality of bite-block vowels. A detailed consideration is given to the implications of these and other findings for two recent perspectives on vowel production.
