Commentary on “Can a good philosophical contribution be made just by asking a question?”

This paper explains some of the reasoning behind “Can a Good Philosophical Contribution Be Made Just by Asking a Question?,” a paper which consists solely in its title and which is published in the same issue of the journal as the present paper. The method for explaining that reasoning consists in making available a lightly edited version of a letter the authors sent to the editors when submitting the title-only paper. The editors permitted publication of that paper on the condition that the authors also separately publish a version of that letter; the present paper aims to fulfil that condition.     

Do Questions Get Infants Talking? Infant Vocal Responses to Questions and Declaratives in Maternal Speech

Maternal questions play a crucial role in early language acquisition by virtue of their special grammatical, prosodic and lexical forms, and their abundance in the input. Infants are able to discriminate questions from other sentence types and produce rising intonations in their own requests. This study examined whether caregiver questions were related to the quantity of infant vocalizations. Thirty‐six infants aged 10 and 14 months participated in a laboratory play session with their mothers. In separate blocks, mothers were instructed to ask questions and to refrain from asking questions. Both block‐level and utterance‐level analyses found no evidence that maternal questions affected the amount of infant‐response vocalizations. Mothers of 14‐month‐olds (but not 10‐month‐olds) tended to repeat questions. Copyright © 2016 John Wiley & Sons, Ltd.     

A Test of Order-Constrained Hypotheses for Circular Data With Applications to Human Movement Science

Researchers studying the movements of the human body often encounter data measured in angles (e.g., angular displacements of joints). The evaluation of these circular data requires special statistical methods. The authors introduce a new test for the analysis of order-constrained hypotheses for circular data. Through this test, researchers can evaluate their expectations regarding the outcome of an experiment directly by representing their ideas in the form of a hypothesis containing inequality constraints. The resulting data analysis is generally more powerful than one using standard null hypothesis testing. Two examples of circular data from human movement science are presented to illustrate the use of the test. Results from a simulation study show that the test performs well.     

The pitch of “real” and “rhetorical” questions directed by a father to his daughter: A longitudinal case study

A longitudinal study of a father and his daughter examined pitch-variation of “real” and “rhetorical” questions. Although the father asked “real” and “rhetorical” questions from the start of the recordings, he did not distinguish them through differential pitch height until the baby was 15 months old.     

Toward an Alliance Between the Issue-Processing Approach and Pragma-Dialectical Analysis

On the approach to discussions of policy choices that treats such discussions as instances of issue-processing, the joint use of the logic of questions and the logic of rules gives precise formulation to two sorts of issues. To one sort of issue belong issue-circumscribing questions; to another sort, issues-simplicter, which consist of disjunctions of policy proposals – so many proposed social rules – that are answers, in the case of each disjunction, to a given issue-circumscribing question. Work in pragma-dialectics can take over the issue-processing approach; and by doing so add to the pragma-dialectical repertory further dimensions in the analysis of issues and in protocol-narratives of discussion. The analysis and narratives would now include accounts of how issue-circumscribing questions generate initial standpoints and how discussions sometimes end with compromises between standpoints. Further research questions follow about transformations of issues and the comparison of successive rounds of discussion. A narrative of one period of discussion during `the War on Drugs' in the United States illustrates these points.
