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.     

Psicologías para la evolución. Catálogo y crítica de los usos actuales de la Selección Orgánica

Resumen

Ofrecemos una clasificación y análisis crítico de los diversos enfoques que hoy reivindican y utilizan la teoría de la Selección Orgánica (o Efecto Baldwin). Desde una perspectiva constructivista denunciamos el uso generalizado de una interpretación reduccionista de la selección orgánica y de un completo olvido de la psicología ligada específicamente a ella, la psicología genética, destinada a explicar la construcción de innovaciones adaptativas. Esto nos permite un análisis de las limitaciones de las variadísimas interpretaciones que en la actualidad se hacen de la selección orgánica; por ejemplo, desde posiciones neodarwinistas—como la de Dennett—, biosemióticas—Deacon—, waddingtonianas—Matsuda—, de Sistemas Complejos—Depew y Weber—, o epigenéticas—Celia Moore—.     

关于哲学的问题研究

“恰当地提出问题”对于哲学甚至比对于科学更为重要,它体现出哲学活动的特殊性质。提问开放新的视域。使我们超出习见,进入思考和对话。着重于提出问题而非构造理论,在今天可以被视为一种研究哲学的方式。当今时代给我们提出了大量需要研究的课题,也要求我们能够提出自己的问题。另一方面,20世纪哲学的自我批判,不仅使哲学的一些基本范畴被重新审视,它的探索方式乃至其功能与合法性根据也受到质询。对问题的研究已成为把握时代和探索哲学发展途径的入手处。     

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.     

The differential effects of solution-focused and problem-focused coaching questions on the affect,attentional control and cognitive flexibility of undergraduate students experiencing study-related stress

Previous research has demonstrated that Solution-Focused (SF) coaching can help individuals to attain positive outcomes. However, not much is known about the processes through which these positive outcomes are achieved. In two experiments, we subjected undergraduate students to either SF or Problem-Focused (PF) questions about their study-related problems. In Experiment 1, we hypothesized and found that SF questioning (as compared to PF questioning) leads to higher positive affect (H1a) and lower negative affect (H1b). Contrary to our expectations, SF questions did not lead to higher attentional control (H2). In Experiment 2, we aimed to replicate the hypotheses for positive and negative affect and additionally hypothesized that SF questioning leads to higher cognitive flexibility (H3a). The results supported these hypotheses. However, our hypothesis that the differential effects of SF and PF questioning on cognitive flexibility are mediated by positive affect (H3b) was not supported. Theoretical and practical implications are discussed.     

Illusory inferences with quantifiers

The psychological study of reasoning with quantifiers has predominantly focused on inference patterns studied by Aristotle about two millennia ago. Modern logic has shown a wealth of inference patterns involving quantifiers that are far beyond the expressive power of Aristotelian syllogisms, and whose psychology should be explored. We bring to light a novel class of fallacious inference patterns, some of which are so attractive that they are tantamount to cognitive illusions. In tandem with recent insights from linguistics that quantifiers like “some” are treated as wh-questions, these illusory inferences are predicted by the erotetic theory of reasoning, which postulates that a process akin to question asking and answering is behind human inference making.     

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.     

Ambiguity and explanation

This paper presents evidence that ‘because’ is importantly ambiguous between two closely related senses covering what are usually called causal explanations, on the one hand, and grounding or metaphysical explanations, on the other hand. To this end, it introduces the lexical categories of monosemy, polysemy and homonymy; describes a test for polysemy; and discusses the results of the test when applied to ‘because’. It also shows how to understand so-called hybrid explanations in light of the semantic facts established by the analysis.     

Effects of circular motion on judgment of rotation direction and depth order in visual motion

Abstract:  The rotation direction and depth order of a rotating sphere consisting of random dots often reverses while it is viewed under orthographic projection. However, if a short viewing distance is simulated under perspective projection, the correct rotation direction can be perceived. There are two motion cues for the rotation direction and depth order. One is the speed cue; points with higher velocities are closer to the observer. The other is the vertical motion cue; vertical motion is induced when the dots recede from or approach the observer. It was examined whether circular motion, which does not have any depth information but induces vertical velocities, masks the vertical motion cue. In Experiment 1, the effects of circular motion on the judgment of the rotation direction of a rotating sphere were examined. The magnitude of the two cues (the speed cue and the vertical velocity cue) as well as the angular speed of circular motion was varied. It was found that the performance improved as the vertical velocity increased and that the speed cue had slight effects on the judgment of the rotation direction. It was also found that the performance worsened as the angular speed of the circular motion was increased. In Experiment 2, the effects of circular motion on depth judgment of a rotating half sphere were investigated. The performance worsened as the angular speed of the circular motion increased, as in Experiment 1. These results suggest that the visual system cannot compensate perfectly for circular motion for the judgment of the rotation direction and depth order.     

Facilitation by Variation: Right-to-Left Learning of English Yes/No Questions

This study advances the hypothesis that optional structural variation in language facilitates syntactic learning (facilitation‐by‐variation). Support for this is provided by a right‐to‐left‐elaboration acquisition model for English yes/no questions (YNQs). Previous studies have focused on the acquisition of ‘‘inverted’’ YNQs, a cornerstone of nativist theories of language development. Data from five American children (1;3 to 5;1) and their parents show that children hear a range of adult questions (Coming?You coming?Are you coming?), not all inverted. These variants are ordered from structurally least complex noncanonical forms to complex canonical inverted forms. I use state‐of‐the‐art econometric techniques to estimate breakpoints in YNQ time series and show that noncanonical questions emerge early in children’s speech and facilitate acquisition of canonical ones. This incremental structure‐building process relies on an adjunction strategy that augments noncanonical questions with initial auxiliaries and subjects. Development proceeds incrementally from right to left to derive auxiliary‐initial structures.
