Dynamically transforming the elements of any performing artist’s craft, this practical guide is a must-have for musicians, dancers, and actors. The handbook shows how artistic performance is embodied in the unification of three critical elements—motion, emotion, and love—demonstrating how it offers experiences and opportunities distinct from the nonperforming arts. Step-by-step guidelines are provided for building intentional and inspirational practice time, thereby enhancing the relationships between the source, the performer, and the audience. Illustrating how intentional movement invokes emotions from both the (...) performer and the audience and how the concept of love gives a performance humanity and life, this eye-opening exploration creates pathways for achieving true artistry.

In a recent article, van Fraassen has taken issue with the use to which Perrin’s experiments on Brownian motion have been put by philosophers, especially those defending scientific realism. He defends an alternative position by analysing the details of Perrin’s case in its historical context. In this reply, I argue that van Fraassen has not done the job well enough and I extend and in some respects attempt to correct his claims by close attention to the historical details.

How do we talk about events we perceive? And how tight is the connection between linguistic and non-linguistic representations of events? To address these questions, we experimentally compared motion descriptions produced by children and adults in two typologically distinct languages, Greek and English. Our findings confirm a well-known asymmetry between the two languages, such that English speakers are overall more likely to include manner of motion information than Greek speakers. However, mention of manner of motion in Greek speakers' descriptions increases (...) significantly when manner is not inferable; by contrast, inferability of manner has no measurable effect on motion descriptions in English, where manner is already preferentially encoded. These results show that speakers actively monitor aspects of event structure, which do not find their way into linguistic descriptions. We conclude that, in regard to the differential encoding of path and manner, which has sometimes been offered as a prime example of the effects of language encoding on non-linguistic thought, surface linguistic encoding neither faithfully represents nor strongly constrains our mental representation of events.

This study sought to find out the effect of the Hot Seat Strategy on eighth graders’ achievement in Wave Motion and Sound Unit in their Life and Science textbook. The researcher used the quasi-experimental design to achieve the aim of the study. The population of the study was all eighth graders (No=934) in Qalqilya public schools. The study sample, randomly chosen, was 208 students in the eighth grade. Of five eighth-grade sections, the researcher randomly chose two sections: one experimental and (...) another control. After data collection, it was obtained that the Hot Seat Strategy positively impacted students’ achievement. There was a statistically significant difference at α = 0.05 in students’ achievement level as well as level of knowledge, memorization, understanding, and application in favor of the experimental group.

It is the aim of work in theoretical cognitive science to produce good theories of what exactly cognition amounts to, preferably theories which not only provide a framework for fruitful empirical investigation, but which also shed light on cognitive activity itself, which help us to understand our place, as cognitive agents, in a complex causally determined physical universe. The most recent such framework to gain significant fame is the so-called dynamical approach to cognition. Explaining and exploring DST is the purpose (...) of the collection Mind as Motion: Explorations in the Dynamics of Cognition, edited by Robert Port and Timothy van Gelder. (shrink)

As I have read the scholium, it divides into three main parts, not including the introductory paragraph. The first consists of paragraphs one to four in which Newton sets out his characterizations of absolute and relative time, space, place, and motion. Although some justificatory material is included here, notably in paragraph three, the second part is reserved for the business of justifying the characterizations he has presented. The main object is to adduce grounds for believing that the absolute quantities are (...) indeed distinct from their relative measures and are not reducible to them. Paragraph five takes this up for the case of time. Paragraphs eight to twelve endeavor to do this for rest and motion by appealing to their properties, causes and effects. In arguing that absolute motion is not reducible to any particular form of the relative motion of bodies with respect to one another, and thus, as is directly argued in the third argument, must be understood in terms of motionless places, Newton thereby constructs an indirect case that absolute space is indeed something distinct from any relative space. Paragraph thirteen functions as conclusion to this line of inquiry and comments on how, in the light of this, the names of these quantities are to be interpreted in the scriptures. The third and final part consists of paragraph fourteen alone, and addresses the question: given that true motion is motion with respect to absolute space, but the parts of the latter are not perceivable, is it possible for us to know the true motions of individual bodies? Newton illustrates how this may be done from the evidence provided by their apparent motions and the forces which are the causes and effects of true motion. This forms a bridge to the body of the work insofar as the purpose of the Principia, according to Newton, is to show how this, and the converse problem, of inferring true and apparent motions from the forces, can be dealt with.Part II of this paper will appear in the next issue of Studies in History and Philosophy of Science.

This paper describes DIVA (Dynamic Imagery for Visual Analogy), a computational model of visual imagery based on the scene graph, a powerful representational structure widely used in computer graphics. Scene graphs make possible the visual display of complex objects, including the motions of individual objects. Our model combines a semantic-network memory system with computational procedures based on scene graphs. The model can account for people’s ability to produce visual images of moving objects, in particular the ability to use dynamic visual (...) analogies that compare two systems of objects in motion.

In this paper we argue that Aristotle operates with a particular theoretical model in his explanation of animal locomotion, what we call the ‘centralized incoming and outgoing motions’ model. We show how the model accommodates more complex cases of animal motion and how it allows Aristotle to preserve the intuition that animals are self-movers, without jeopardizing his arguments for the eternity of motion and the necessary existence of one eternal unmoved mover in Physics VIII. The CIOM model helps to elucidate (...) Aristotle’s two central yet problematic claims, namely that the soul is the efficient cause of animal motion and that it is the internal supporting-point necessary for animal motion. Moreover, the CIOM model helps us to explain the difference between voluntary, involuntary and non-voluntary motions, and to square Aristotle’s cardiocentrism with his hylomorphism, but also, more generally, it provides an interesting way of thinking about the place of intentionality in the causal structure of the world.

It is well known that languages differ in how they encode motion. Languages such as English use verbs that communicate the manner of motion (e.g., climb, float), while languages such as Greek often encode the path of motion in verbs (e.g., advance, exit). In two studies with English- and Greek-speaking adults and 5-year-olds, we ask how such lexical constraints are used in combination with structural cues in hypothesizing meanings for novel motion verbs cross-linguistically. We show that lexicalization biases affect the (...) interpretations of motion verbs in both young children and adults across different languages; furthermore, their scope of application is larger than previously thought, since they also extend to the domain of caused motion events. Crucially, we find that the language-specific effects of such biases interact with universal mappings between syntactic structure and semantic content. Finally, we demonstrate that the combined effects of lexical and structural cues shift non-linguistic biases observed during event categorization: even though speakers of English and Greek share non-linguistic preferences in categorizing spontaneous and caused motion, they focus on different components of motion events when building hypotheses about the meaning of novel motion verbs.

Hud Hudson has recently suggested a scenario intended to show that, assuming the doctrine of temporal parts and a sufficiently liberal view of composition, there are material objects that move faster than light. I accept Hudson's conditional but contend that his modus ponens is less plausible that the corresponding modus tollens. Reversed in this way, the argument stemming from the scenario raises the cost of mereological liberalism and advances the case for a principled restriction on diachronic composition.

Future robots should have common sense about the world in order to handle the problems they will encounter. A large part of this commonsense knowledge must be naive physics knowledge, since carrying out even the simplest everyday chores requires familiarity with physics laws. But how should one start codifying this knowledge? What kind of skills should be elicited from the experts (each and every one of us)? This paper will attempt to provide some hints by studying the mental models of (...) force and motion. (shrink)

This handbook brings together essays in the philosophy of film and motion pictures from authorities across the spectrum. It boasts contributions from philosophers and film theorists alike, with many essays employing pluralist approaches to this interdisciplinary subject. Core areas treated include film ontology, film structure, psychology, authorship, narrative, and viewer emotion. Emerging areas of interest, including virtual reality, video games, and nonfictional and autobiographical film also have dedicated chapters. Other areas of focus include the film medium’s intersection with contemporary social (...) issues, film’s kinship to other art forms, and the influence of historically seminal schools of thought in the philosophy of film. Of emphasis in many of the essays is the relationship and overlap of analytic and continental perspectives in this subject. (shrink)

Eye-related movements such as blinks and microsaccades are modulated during bistable perceptual tasks. However, if they play an active role during internal perceptual switches is not known. We conducted two experiments involving an ambiguous plaid stimulus, wherein participants were asked to continuously report their percept, which could consist of either unidirectional coherent or bidirectional component movement. Our main results show that blinks and microsaccades did not facilitate perceptual switches. On the contrary, a reduction in eye movements preceded the perceptual switch. (...) Blanks, on the other hand, thought to mimic the retinal consequences of a blink, consistently led to a switch. Through the timing of the blank-introduced perceptual change, we were able to estimate the delay between the internal switch and the response. This delay further allowed us to evaluate that the reduction in blink probability co-occurred with the internal perceptual switch. Additionally, our results indicate that distinct internal processes underlie the switch to coherent vs. component percept. Blanks exclusively facilitated a switch to the coherent percept, and only the switch to coherent percept was followed by an increase in blink rate. In a second study, we largely replicated the findings and included a microsaccade analysis. Microsaccades only showed a weak relation with perceptual switches, but their direction was correlated with the perceived motion direction. Nevertheless, our data suggests an interaction between microsaccades and blinks by showing that microsaccades were differently modulated around blinks compared with blanks. This study shows that a reduction in eye movements precedes internal perceptual switches indicating that the rate of blinks can set the stage for a reinterpretation of sensory input. While a perceptual switch based on changed sensory input usually leads to an increase in blink rate, such an increase was only present after the perceptual switch to coherent motion but absent after the switch to component percept. This provides evidence of different underlying mechanism or internal consequence of the two perceptual switches and suggests that blinks can uncover differences in internal percept-related processes that are not evident from the percept itself.

Self-initiated action effects are often perceived as less intense than identical but externally generated stimuli. It is thought that forward models within the sensorimotor system pre-activate cortical representations of predicted action effects, reducing perceptual sensitivity and attenuating neural responses. As self-agency and predictability are seldom manipulated simultaneously in behavioral experiments, it is unclear if self-other differences depend on predictable action effect contingencies, or if both self- and externally generated stimuli are modulated similarly by predictability. We factorially combined variation in predictability (...) of action effects, spatial congruence, and performance by the self or computer to dissociate these influences on a visual discrimination task. Participants performed 2AFC speed judgments. Self-initiated motion was judged to be slower than computer-initiated motion when action effect contingencies were predictable, while spatial congruence influenced speed judgments only when action effect contingencies were unpredictable. Results are discussed in relation to current theories of sensory attenuation. (shrink)

In the present paper we study the relationship between the notions of force, cause and subject of motion in Leibniz’s early dynamics. First, we specify the role that the problem of the subject and cause of motion played in the development of his dynamics. Second, we analyze the distinction between force and quantity of motion and the validity and limits of his proof. Third, we study and evaluate the limits of the arguments for establishing that forces are inherent to bodies. (...) Our main goal is to show that between 1678 and 1686 Leibniz dissociates the problem of the subject from the problem of the cause of motion and, furthermore, that even though the problem of establishing that force is inherent to particular bodies played a major role in the discovery of his dynamics, it has no place in its justification.
