Our minds are severely limited in how much information they can extensively process, in spite of being massively parallel at the visual end. When people attempt to track moving objects, only a limited number can be tracked, which varies with display parameters. Associated experiments indicate that spatial selection and updating has higher capacity than selection and updating of features such as color and shape, and is mediated by processes specific to each cerebral hemisphere, such that each hemifield has its own spatial tracking limit. These spatial selection processes act as a bottleneck that gate subsequent processing. To improve our understanding of this bottleneck, future work should strive to avoid contamination of tracking tasks by high-level cognition. While we are far from fully understanding how attention keeps up with multiple moving objects, what we already know illuminates the architecture of visual processing and offers promising directions for new discoveries.

Even the simplest social interactions require us to gather, integrate, and act upon, multiple streams of information about others and our surroundings. In this Element, we discuss how perceptual processes provide us with an accurate account of action-relevant information in social contexts. We overview contemporary theories and research that explores how: (1) individuals perceive others' mental states and actions, (2) individuals perceive affordances for themselves, others, and the dyad, and (3) how social contexts guide our attention to modulate what we perceive. Finally, we review work on the cognitive mechanisms that make joint action possible and discuss their links to perception.

This Element reviews literature on the physiological influences of music during perception and action. It outlines how acoustic features of music influence physiological responses during passive listening, with an emphasis on comparisons of analytical approaches. It then considers specific behavioural contexts in which physiological responses to music impact perception and performance. First, it describes physiological responses to music that evoke an emotional reaction in listeners. Second, it delineates how music influences physiology during music performance and exercise. Finally, it discusses the role of music perception in pain, focusing on medical procedures and laboratory-induced pain with infants and adults.

Empathy provides a cognitive and emotional bridge that connects individuals and promotes prosocial behavior. People empathize with others via two complementary perceptual routes: Cognitive Empathy or the ability to accurately recognize and understand others' emotional states, and Affective Empathy or the ability to 'feel with' others. This Element reviews past and current research on both cognitive and affective empathy, focusing on behavioral, as well as neuroscientific research. It highlights a recent shift towards more dynamic and complex stimuli which may capture better the nature of real social interaction. It expands on why context is crucial when perceiving others' emotional state, and discusses gender differences, biases affecting our understanding of others, and perception of others in clinical conditions. Lastly, it highlights proposed future directions in the field.

The human ability to effortlessly understand the actions of other people has been the focus of research in cognitive neuroscience for decades. What have we learned about this ability, and what open questions remain? In this Element the authors address these questions by considering the kinds of information an observer may gain when viewing an action. A 'what, how, and why' framing organises evidence and theories about the representations that support classifying an action; how the way an action is performed supports observational learning and inferences about other people; and how an actor's intentions are inferred from her actions. Further evidence shows how brain systems support action understanding, from research inspired by 'mirror neurons' and related concepts. Understanding actions from vision is a multi-faceted process that serves many behavioural goals, and is served by diverse mechanisms and brain systems.

The visual world is full of detail. This Element focuses on this variability in perception, asking how it affects performance in visual tasks and how the variability is represented by human observers. The authors highlight different methods for assessing representations of variability and suggest that understanding visual variability can be elusive when straightforward explicit methods are used, while more implicit methods may be better suited to uncovering such processing. The authors conclude that variability is represented in far more detail than previously thought and that this aspect of perception is vital for understanding the complexity of visual consciousness.

This Element reviews the current state of what is known about the visual and vestibular contributions to our perception of self-motion and orientation with an emphasis on the central role that gravity plays in these perceptions. The Element then reviews the effects of impoverished challenging environments that do not provide full information that would normally contribute to these perceptions (such as driving a car or piloting an aircraft) and inconsistent challenging environments where expected information is absent, such as the microgravity experienced on the International Space Station.

This Element examines the influence of expectation and attention on conscious perception. It explores the debate on whether attention is necessary for conscious perception by presenting empirical evidence from studies on inattentional blindness, change blindness, and the attentional blink. While the evidence strongly suggests that attention is necessary for conscious perception, other research has shown that expectation can shape perception, sometimes leading to illusory experiences where predicted stimuli are perceived despite their absence. This phenomenon, termed 'expectation awareness', suggests that attention may not be necessary for all conscious experiences. These findings are explored within the predictive processing framework, where the brain is characterized as a prediction engine, continuously updating its internal models to minimize prediction errors. Integrating findings from psychology, neuroscience, and cognitive science, this Element provides a predictive processing model of how attention and expectation construct perceptual reality. It also discusses clinical and theoretical implications and suggests future research.

Consciousness is often treated as unitary phenomenon. We challenge this and propose a framework that parses it into two functionally distinct representational media. Reviewing dominant theories, as well as studies of perceptual failures, neural activity, visual search and attention - we argue that phenomenal experience arises early as a detailed, analogue, and relatively generic representation of the physical world. Awareness, a later and more idiosyncratic representation of the world, results from enriching phenomenal experience via relevance-filtered semantic knowledge. This Multi-Representational Media (MRM) account unifies perception, memory, and cognition, reconciles rich and sparse consciousness views, and reframes concepts in unconscious cognition research.

The interactions between the senses are essential for cognitive functions such as perception, attention, and action planning. Past research helped understanding of multisensory processes in the laboratory. Yet, the efforts to extrapolate these findings to the real-world are scarce. Extrapolation to real-world contexts is important for practical and theoretical reasons. Multisensory phenomena might be expressed differently in real-world settings compared to simpler laboratory situations. Some effects might become stronger, others may disappear, and new outcomes could be discovered. This Element discusses research that uncovers multisensory interactions under complex environments, with an emphasis on the interplay of multisensory mechanisms with other processes.

Working memory and perceptual attention are related functions, engaging many similar mechanisms and brain regions. As a consequence, behavioral and neural measures often reveal competition between working memory and attention demands. Yet there remains widespread debate about how working memory operates, and whether it truly shares processes and representations with attention. This Element will examine local-level representational properties to illuminate the storage format of working memory content, as well as systems-level and brain network communication properties to illuminate the attentional processes that control working memory. The Element will integrate both cognitive and neuroscientific accounts, describing shared substrates for working memory and perceptual attention, in a multi-level network architecture that provides robustness to disruptions and allows flexible attentional control in line with goals.

This Element looks at the physiological and social roles of taste and the proximal chemical senses. First, how we perceive food and people when we contact them is discussed. These perceptions help us identify what we are eating and with whom we are present and serves as an analysis of the complex scene. Second, the influence of taste in food choice, metabolism, and nutrition is considered. Next, the impact of taste and the proximal chemical senses in social interactions is examined, including social eating. Then, the role of taste and the proximal chemical senses in emotion is explored.

Human color perception is widely understood to be based on a neural coding system involving signals from three distinct classes of retinal photoreceptors. This retina processing model has long served as the mainstream scientific template for human color vision research and has also proven to be useful for the practical design of display technologies, user interfaces, and medical diagnosis tools that enlist human color perception behaviors. Recent findings in the area of retinal photopigment gene sequencing have provided important updates to our understanding of the molecular basis and genetic inheritance of individual variations of human color vision. This Element focuses on new knowledge about the linkages between color vision genetics and color perception variation and the color perception consequences of inheriting alternative, nonnormative, forms of genetic sequence variation.

Hypothesis testing is a common statistical analysis for empirical data generated by studies of perception, but its properties and limitations are widely misunderstood. This Element describes several properties of hypothesis testing, with special emphasis on analyses common to studies of perception. The author also describes the challenges and difficulties with using hypothesis testing to interpret empirical data. Many common applications of hypothesis testing inflate the intended Type I error rate. Other aspects of hypothesis tests have important implications for experimental design. Solutions are available for some of these difficulties, but many issues are difficult to deal with.

Humans can focus their attention narrowly (e.g., to read this text) or broadly (e.g., to determine which way a large crowd of people are moving). This Element comprehensively considers attentional breadth. Section 1 introduces the concept of attentional breadth, while Section 2 considers measures of attentional breadth. In particular, this section provides a critical discussion of the types of psychometric evidence which should be sought to establish the validity of measures of attentional breadth and reviews the available evidence through this lens. Section 3 considers the visual task performance consequences of attentional breadth, including prescribing several key methodological criteria that studies that manipulate attentional breadth need to meet, as well as a discussion of relevant theories and avenues for future theoretical development. Section 4 discusses the utility of the exogenous-endogenous distinction from covert shifts of attention for understanding the performance consequences of attentional breadth. Finally, Section 5 provides concluding remarks.

This Element examines visual perception in the context of activities that involve moving about in complex, dynamic environments. A central theme is that the ability of humans and other animals to perceive their surroundings based on vision is profoundly shaped by the need to adaptively regulate locomotion to variations in the environment. As such, important new insights into what and how we perceive can be gleaned by investigating the connection between vision and the control of locomotion. I present an integrated summary of decades of research on the perception of self-motion and object motion based on optic flow, the perception of spatial layout and affordances, and the control strategies for guiding locomotion based on visual information. I also explore important theoretical issues and debates, including the question of whether visual control relies on internal models.

In this Element, a framework is proposed in which it is assumed that visual selection is the result of the interaction between top-down, bottom-up and selection-history factors. The Element discusses top-down attentional engagement and suppression, bottom-up selection by abrupt onsets and static singletons as well as lingering biases due to selection-history entailing priming, reward and statistical learning. We present an integrated framework in which biased competition among these three factors drives attention in a winner-take-all-fashion. We speculate which brain areas are likely to be involved and how signals representing these three factors feed into the priority map which ultimately determines selection.

How does experience change the way we perceive the world? This Element explores the interaction between perception and experience by studying perceptual experts, people who specialize in recognizing objects such as birds, automobiles, dogs. It proposes perceptual expertise promotes a downward shift in object recognition where experts recognize objects in their domain of expertise at a more specific level than novices. To support this claim, it examines the recognition abilities and brain mechanisms of real-world experts. It discusses the acquisition of expertise by tracing the cognitive and neural changes that occur as a novice becomes an expert through training and experience. Next, it looks "under the hood" of expertise and examines the perceptual features that experts bring to bear to facilitate their fast, accurate, and specific recognition. The final section considers the future of human expertise as deep learning models and artificial intelligence compete with human experts in medical diagnosis.

Cognitive neuroscientists have started to uncover the neural substrates, systems, and mechanisms enabling us to prioritize the processing of certain sensory information over other, currently less-relevant, inputs. However, there is still a large gap between the knowledge generated in the laboratory and its application to real-life problems of attention as when, for example, interface operators are multi-tasking. In this Element, laboratory studies on crossmodal attention (both behavioural/psychophysical and cognitive neuroscience) are situated within the applied context of driving. We contrast the often idiosyncratic conditions favoured by much of the laboratory research, typically using a few popular paradigms involving simplified experimental conditions, with the noisy, multisensory, real-world environments filled with complex, intrinsically-meaningful stimuli. By drawing attention to the differences between basic and applied studies in the context of driving, we highlight a number of important issues and neglected areas of research as far as the study of crossmodal attention is concerned.

Visual cognitive processes have traditionally been examined with simplified stimuli, but generalization of these processes to the real-world is not always straightforward. Using images, computer-generated images, and virtual environments, researchers have examined processing of visual information in the real-world. Although referred to as scene perception, this research field encompasses many aspects of scene processing. Beyond the perception of visual features, scene processing is fundamentally influenced and constrained by semantic information as well as spatial layout and spatial associations with objects. In this review, we will present recent advances in how scene processing occurs within a few seconds of exposure, how scene information is retained in the long-term, and how different tasks affect attention in scene processing. By considering the characteristics of real-world scenes, as well as different time windows of processing, we can develop a fuller appreciation for the research that falls under the wider umbrella of scene processing.
