Janet Taylor Spence: A Model Role Model

The article summarizes and reflects on the contributions of Janet Taylor Spence in the areas of editing, service to her institutions, and service to her profession. It is based on both the objective record and on the personal experience and observations of the author, a long-time colleague. It reviews the many editorial positions Janet Taylor Spence held, including being editor of the Annual Review of Psychology and Contemporary Psychology, and the award she received from the National Academy of Sciences. It also sketches many of the leadership positions she held, including being president of the American Psychological Association and the first elected president of the Association for Psychological Science. It emphasizes both her outstanding professional and personal qualities.     

Identifying the speech codes

Models of speech processing typically assume that speech is represented by a succession of codes. In this paper we argue for the psychological validity of a prelexical (phonetic) code and for a postlexical (phonological) code. Whereas phonetic codes are computed directly from an analysis of input acoustic information, phonological codes are derived from information made available subsequent to the perception of higher order (word) units. The results of four experiments described here indicate that listeners can gain access to, or identify, entities at both of these levels. In these studies listeners were presented with sentences and were asked to respond when a particular word-initial target phoneme was detected (phoneme monitoring). In the first three experiments speed of lexical access was manipulated by varying the lexical status (word/nonword) or frequency (high/low) of a word in the critical sentences. Reaction times (RTs) to target phonemes were unaffected by these variables when the target phoneme was on the manipulated word. On the other hand, RTs were substantially affected when the target-bearing word was immediately after the manipulated word. These studies demonstrate that listeners can respond to the prelexical phonetic code. Experiment IV manipulated the transitional probability (high/low) of the target-bearing word and the comprehension test administered to subjects. The results suggest that listeners are more likely to respond to the postlexical phonological code when contextual constraints are present. The comprehension tests did not appear to affect the code to which listeners responded. A “Dual Code” hypothesis is presented to account for the reported findings. According to this hypothesis, listeners can respond to either the phonetic or the phonological code, and various factors (e.g., contextual constraints, memory load, clarity of the input speech signal) influence in predictable ways the code that will be responded to. The Dual Code hypothesis is also used to account for and integrate data gathered with other experimental tasks and to make predictions about the outcome of further studies.     

Blood donation and the foot-in-the-door technique: a limiting case.

Three experiments testing the effectiveness of the foot-in-the-door technique for recruiting blood donors consistently failed to demonstrate that this procedure influences either verbal or behavioral compliance, suggesting that the generality of the foot-in-the-door phenomenon is limited. Experiment 1 attempted to demonstrate that an earlier failure of this technique was due to poor operationalization rather than to the magnitude of the critical request or to the invalidity of the phenomenon, but it failed to do so. Experiment 2, designed to more closely resemble other foot-in-the-door studies by using telephone contacts and an initial request for persons to answer questions, was conducted to examine other possible explanations for the two previous failures. This experiment also failed to show any foot-in-the-door effect. Experiment 3 was a conceptual replication of Experiment 2 but used personal contacts. One apparent foot-in-the-door effect emerged in this case, but it was more likely due to a factor other than the experimental treatment. It is concluded that although the foot-in-the-door procedure may indeed influence verbal compliance with requests for minimal forms of aid, it probably will not significantly affect people's willingness to comply with more substantial requests involving behaviors that are psychologically costly to perform.     

Causal and Constitutive Relations, and the Squaring of Coleman’s Diagram: Reply to Vromen

We respond to Jack Vromen’s (this issue) critique of our discussion of the missing micro-foundations of work on routines and capabilities in economics and management research. Contrary to Vromen, we argue that (1) inter-level relations can be causal, and that inter-level causal relations may also obtain between routines and actions and interactions; (2) there are no macro-level causal mechanisms; and (3) on certain readings of the notion of routines and capabilities, these may be macro causes.     

The Biomedical Paradigm and the Nobel Prize: Is It Time for a Change?

An examination of the early history of Nobel Committee deliberations, coupled with a survey of discoveries for which prizes have been awarded to date – and, equally revealing, discoveries for which prizes have not been awarded – reveals a pattern. This pattern suggests that Committee members may have internalized the received, biomedical model and conferred awards in accord with the physicalistic premises that ground this model. I consider the prospect of a paradigm change in medical science and the possible repercussions of such a change on the distribution of Nobel prizes within the domain of physiology or medicine. For expository purposes, I contrast a model based on a science of pathophysiology with one based on a science of pathopsychophysiology. I propose a means whereby members might minimize the potentially blinding effects of model-dependence and come to evaluate medical discoveries from an inter-model rather than an exclusively intra-model perspective. By bringing to light questions rarely asked and proposing answers, I seek to open a dialogue and furnish a vehicle by which the putative delimiting effects of model-dependence might be overcome.     

Decision processes during sentence comprehension: Effects of surface structure reconsidered

Previous experiments have yielded conflicting results concerning the utility of relative pronouns as cues to the deep structure underlying self-embedded (SE) sentences. The present study investigated the usefulness of this cue. At the same time, it compared the relative sensitivity of two measures of sentence-comprehension difficulty: paraphrasing and phoneme monitoring. Forty Ss heard SE sentences, one-half of which had the relative pronouns deleted. The presence or absence of the relative pronouns in a particular sentence was counterbalanced across groups. The Ss also heard right-branching sentences. It was found that presence of the relative pronouns led to significantly faster phoneme monitoring times and to marginally better paraphrasing (i.e., to better comprehension) in the SE sentences. It was concluded that relative pronouns are effective cues and, further, that the phoneme monitoring technique is a better index of comprehension difficulty than the paraphrasing technique. Reasons for the previous experimental discrepancies were discussed.
