Book Description
The human visual system is exquisitely sensitive to dynamics. Causalityis a key concept for human thought and action: The world around us appears as acoherent flow of events, each event caused by others which are in turn caused by other events, and so on. Albert Michotte (1963) showed that humans perceive causality directly or indirectly as a low-level perceptual event. As a result, theimpression of purposeful, intentional relations are "surprisingly easy" to obtain. Despite traditional claims to the contrary, observers are reasonably sensitive to physical and social causality in the real world, at least if they have relevant knowledge of causal structures in schematic motion events. In this thesis the influence of physical factors on 'action radius', up to the extent that the motion of the second object is seen to be caused by the first object is measured. Physical factors such as the speed of the passive object, the juxtaposition of collision in the context of variations in the arrival of Object A and departure of Object B (from some point in space) and the effects of negative delays (Object B departure is prior to Object A motion termination) were explored. Resulted that perceived causality is shown to be a function, not only of automatic processing but also constitutes a perception-action heuristic which is shown to be strategic in operation and at the same time exquisitely sensitive to the temporal structure of external events.

Book Description
Originally published in 1963, this is a classic work on the psychology of perception. By means of suitable patterns on a partly concealed rotating disc Michotte was able to give the impression of objects in movement; and where certain conditions of speed, position, and time-interval were satisfied, his subjects received the impression of a causal interaction between two objects – for example, the impression that one object has ‘bumped into’ another (the ‘Launching Effect’) or is carrying it along (the ‘Entraining Effect’). In a further group of experiments Michotte studies the conditions in which moving objects look as though they are alive. A large number of experiments are described, and on the basis of them Michotte formulates a theory as to the conditions in which causal impressions occur. He also compares his own views on causality with those of Hume, Maine de Biran, and Piaget.

Book Description
The problem of how humans and other intelligent systems construct causal representations from non-causal perceptual evidence has occupied scholars in cognitive science for many decades. Most contemporary approaches agree with David Hume that patterns of covariation between two events of interest are the critical input to the causal induction engine, irrespective of whether this induction is believed to be grounded in the formation of associations (Shanks & Dickinson, 1987), rule-based evaluation (White, 2004), appraisal of causal powers (Cheng, 1997), or construction of Bayesian Causal Networks (Pearl, 2000). Recent research, however, has repeatedly demonstrated that an exclusive focus on covariation while neglecting contiguity (another of Hume’s cues) results in ecologically invalid models of causal inference. Temporal spacing, order, variability, predictability, and patterning all have profound influence on the type of causal representation that is constructed. The influence of time upon causal representations could be seen as a bottom-up constraint (though current bottom-up models cannot account for the full spectrum of effects). However, causal representations in turn also constrain the perception of time: Put simply, two causally related events appear closer in subjective time than two (equidistant) unrelated events. This reversal of Hume’s conjecture, referred to as Causal Binding (Buehner & Humphreys, 2009) is a top-down constraint, and suggests that our representations of time and causality are mutually influencing one another. At present, the theoretical implications of this phenomenon are not yet fully understood. Some accounts link it exclusively to human motor planning (appealing to mechanisms of cross-modal temporal adaptation, or forward learning models of motor control). However, recent demonstrations of causal binding in the absence of human action, and analogous binding effects in the visual spatial domain, challenge such accounts in favour of Bayesian Evidence Integration. This Research Topic reviews and further explores the nature of the mutual influence between time and causality, how causal knowledge is constructed in the context of time, and how it in turn shapes and alters our perception of time. We draw together literatures from the perception and cognitive science, as well as experimental and theoretical papers. Contributions investigate the neural bases of binding and causal learning/perception, methodological advances, and functional implications of causal learning and perception in real time.

Book Description
This book is concerned with sensory cue integration both within and between sensory modalities, and focuses on the emerging way of thinking about cue combination in terms of uncertainty. These probabilistic approaches derive from the realization that our sensors are noisy and moreover are often affected by ambiguity. For example, mechanoreceptor outputs are variable and they cannot distinguish if a perceived force is caused by the weight of an object or by force we are producing ourselves. The probabilistic approaches elaborated in this book aim at formalizing the uncertainty of cues. They describe cue combination as the nervous system's attempt to minimize uncertainty in its estimates and to choose successful actions. Some computational approaches described in the chapters of this book are concerned with the application of such statistical ideas to real-world cue-combination problems. Others ask how uncertainty may be represented in the nervous system and used for cue combination. Importantly, across behavioral, electrophysiological and theoretical approaches, Bayesian statistics is emerging as a common language in which cue-combination problems can be expressed.

Book Description
"In Perception: First Form of Mind, Tyler Burge develops an understanding of the most primitive type of representational mind: perception. Focusing on its form, function, and underlying capacities, as indicated in the sciences of perception, Burge provides an account of the representational content and formal representational structure of perceptual states, and develops a formal semantics for them. The account is elaborated by an explanation of how the representational form is embedded in an iconic format. These structures are then situated in current theoretical accounts of the processing of perceptual representations, with an emphasis on the formation of perceptual categorizations. An exploration of the relationship between perception and other primitive capacities-conation, attention, memory, anticipation, affect, learning, and imagining-clarifies the distinction between perceiving, with its associated capacities, and thinking, with its associated capacities. Drawing on a broad range of historical and contemporary research, rather than relying on introspection or ordinary talk about perception, Perception: First Form of Mind is a scientifically rigorous and agenda-setting work in the philosophy of perception and the philosophy of science"--

Book Description
To be a 'commonsense realist' is to hold that perceptual experience is (in general) an immediate awareness of mind-independent objects, and a source of direct knowledge of what such objects are like. Over the past few centuries this view has faced formidable challenges from epistemology, metaphysics, and, more recently, cognitive science. However, in recent years there has been renewed interest in it, due to new work on perceptual consciousness, objectivity, and causal understanding. This volume collects nineteen original essays by leading philosophers and psychologists on these topics. Questions addressed include: What are the commitments of commonsense realism? Does it entail any particular view of the nature of perceptual experience, or any particular view of the epistemology of perceptual knowledge? Should we think of commonsense realism as a view held by some philosophers, or is there a sense in which we are pre-theoretically committed to commonsense realism in virtue of the experience we enjoy or the concepts we use or the explanations we give? Is commonsense realism defensible, and if so how, in the face of the formidable criticism it faces? Specific issues addressed in the philosophical essays include the status of causal requirements on perception, the causal role of perceptual experience, and the relation between objective perception and causal thinking. The scientific essays present a range of perspectives on the development, phylogenetic and ontogenetic, of the human adult conception of perception.
