Response conflict theory,error rates and hybrid processing: A reply to McLeod

McLeod (1977) has proposed a parallel processing model of the psychological refractory period quite similar to an earlier model most recently adumbrated by Kantowitz (1974a). This article corrects some erroneous statements made by McLeod about the testability of the response conflict model and emphasizes the importance of error data in distinguishing among conceptually similar models of the PRP effect.     

A Plumber's friend in need is a Plumber's friend indeed

In response to the critique of Gaes, Quigley-Fernandez, and Tedeschi (Journal of Research in Personality, 1978, 12, 189–192) it was acknowledged that the cell Ns were incorrect as originally reported, and the weakness of a postexperimental division of subjects was reaffirmed. Emphasis was placed on the comparability of a simple rating scale and an elaborate bogus pipeline in measuring attraction. The need for determining the way in which the bogus pipeline functions prior to its uncritical adoption in any given experimental situation was stressed as a point of agreement.     

Effect of sentence structure on stuttering

The elicited speech of 20 adult male stutterers was analyzed to determine the effect of the number, type, and location of relative clause structures on the frequency of stuttering. The selected structures were identified on the basis of transformational grammar. The findings indicate that the frequency of stuttering increases significantly with an increase in the number of relative clauses included in a matrix sentence structure. The results also indicate that the more severe the stuttering is, the more the stutterer is likely to be affected by this variable. Trends toward more frequent stuttering in the postverbal relative clause and the adjectival form of the relative clause were observed.
