This article presents theories of attention that attempt to derive their answer to the question of what attention is from their answers to the question of what it is for some activity to be done attentively. Such theories provide a distinctive account of the difficulties that are faced by the attempt to locate processes in the brain by which the phenomena of attention can be explained. Their account does not share the pessimism of theories suggesting that the concept of attention is defective. Instead it reconstrues the explanatory relationship between attention and the processes that constitute it, in a way that is illustrated here by considering the relationship between attention and the processes that are identified by the biased competition theory. After considering some of the ways in which an adverbialist approach might be developed, the article concludes by suggesting some possible solutions to a problem concerning distraction, by which prominent adverbialist theories of attention have been dogged.

Everyone knows what paying attention is, yet not everybody knows what this means in cognitive and brain function terms. The attentive state can be defined as a state of optimal activation that allows selecting the sources of information and courses of action in order to optimize our interaction with the environment in accordance with either the saliency of the stimulation or internal goals and intentions. In this article we argue that paying attention consists in tuning the mind with the environment in a conscious and controlled mode in order to enable the strategic and flexible adaptation of responses in accordance with internal motivations and goals. We discuss the anatomy and neural mechanisms involved in attention functions and present a brief overview of the neurocognitive development of this seminal cognitive function on the grounds of self-regulated behavior.

This opinion piece is part of a collection on the topic: "What is attention?" Despite the word's place in the common vernacular, a satisfying definition for "attention" remains elusive. Part of the challenge is there exist many different types of attention, which may or may not share common mechanisms. Here we review this literature and offer an intuitive definition that draws from aspects of prior theories and models of attention but is broad enough to recognize the various types of attention and modalities it acts upon: attention as a multi-level system of weights and balances. While the specific mechanism(s) governing the weighting/balancing may vary across levels, the fundamental role of attention is to dynamically weigh and balance all signals-both externally-generated and internally-generated-such that the highest weighted signals are selected and enhanced. Top-down, bottom-up, and experience-driven factors dynamically impact this balancing, and competition occurs both within and across multiple levels of processing. This idea of a multi-level system of weights and balances is intended to incorporate both external and internal attention and capture their myriad of constantly interacting processes. We review key findings and open questions related to external attention guidance, internal attention and working memory, and broader attentional control (e.g., ongoing competition between external stimuli and internal thoughts) within the framework of this analogy. We also speculate about the implications of failures of attention in terms of weights and balances, ranging from momentary one-off errors to clinical disorders, as well as attentional development and degradation across the lifespan.

'Everyone knows what attention is' according to William James. Much work on attention in psychology and neuroscience cites this famous phrase only to quickly dismiss it. But James is right about this: 'attention' was not introduced into psychology and neuroscience as a theoretical concept. I argue that we should therefore study attention with broadly the same methodology that David Marr has applied to the study of perception. By focusing more on Marr's Computational Level of analysis, we arrive at a unified answer to the question of what attention is, what role it plays in the mind, and why organisms like us have that capacity. I propose a methodology for studying attention at Marr's Computational Level that optimizes in a three-dimensional space: it should capture core aspects of our first-person experience of attention, be explanatorily powerful in psychology and neuroscience, and fertile in an interdisciplinary context. I show how this methodology leads to what I call the priority structure account of attention. Attention is what organizes current information to make it more useful for the organism. We can identify it by four features. Attention, in this way, helps a cognitive system to integrate its informational state with its current motivational state. I describe how this account improves on alternatives and shows why attention is a useful concept in many disciplines and for connecting them.

Conceptual fragmentation is when a term assumed to have one meaning is found to have many. When these different definitions overlap in meaning and application confusion and wasted effort follows. "Attention" is such a fragmented term. The response to conceptual fragmentation is simple. Stop using the original term. Our reticence to do so reflects false beliefs about attention. "Attention" is not an old term, but a modern one. Its original meaning is not related to our contemporary intuitions. Attention is not a necessary concept; psychology made substantial progress, even in cognitive areas, during the years when its use was banished. Attention is just one among many examples of conceptual fragmentation in psychology. The root cause is a dearth of theory driving cognitive experimentation. Theoretical clarity is enhanced when fundamental concepts can be expressed in a mathematical form. When theories are stated in mathematical language it opens the door to rigorous cross-domain comparisons using tools like category theory.

Attention prioritizes certain information at the expense of other information in ways that are similar across vision, audition, and other sensory modalities. It influences how-and even what-information is represented and processed, affecting brain activity at every level. Much of the core research into cognitive and neural mechanisms of attention has used visual tasks. However, the same top-down, object-based, and bottom-up attentional processes shape auditory perception, largely through the same underlying, cognitive networks.

Cognitive linguists are increasingly extending their paradigm to include the study of gestures. The bottom-up, usage-based approach in cognitive linguistics has advanced the methods for identifying gesture functions, starting from a detailed analysis of gesture forms. Theoretical notions from cognitive linguistics also help explain the means by which the forms of gestures can be interpreted as meaningful functions. Principles of conceptual metonymy explain how gestures indicate referents through the partial representation of their features that are relevant in the context of use. Conceptual metaphor theory sheds light on how abstract notions can be represented in gesture via comparison with physical source domains. Furthermore, every gestural representation inherently requires the gesturing speaker to employ a specific viewpoint for their depiction-something which is normally not expressed verbally. These aspects of gesture provide insights into processes of thinking for speaking that can be exploited in various fields of cognitive science research. Referential gestures also normally combine pragmatic and interactive functions (showing stance-taking, for example) with representational or deictic functions. The multiple functions of gesture combined with those of speech raise questions for further research about how viewing-listeners interpret and combine information from the multiple semiotic systems employed by gesturing-speakers. Finally, gesture use has been shown to correlate not only with lexical concepts but also in some ways with grammatical constructions. This gives rise to fundamental questions about what constitutes the grammar of a language. Gesture analysis thus raises issues for consideration in any research in cognitive science that concerns spoken language.

Metacognition, or thinking about thinking, is a phenomenon that has received much attention across the numerous fields of Psychological Science. The overarching goal has centered on understanding how humans monitor their internal mental processes and exert control over these processes. However, discipline-focused approaches with little generalized discussion across the field have yielded an incomplete understanding of the construct of metacognition. Consider, for example, the cognitive approach: from this perspective, researchers have developed predictive models and useful frameworks. Further, the field has produced sophisticated techniques to measure monitoring accuracy and define attributes that contribute to monitoring assessments and control process selection. However, the impact of this research has been relatively limited and isolated from metacognitive investigations that consider other important constructs such as motivation and affect. The approaches taken in subfields, such as educational psychology, emotion, and neuropsychology when combined with the cognitive approach, may result in a more complete picture and thorough understanding of metacognition. In this article, we present an argument that the study of metacognition should bridge the various subfields of psychological inquiry. We present a framework toward an integrative approach to understanding metacognition as a complementary process to meta-affect and encourage researchers to consider the study of metacognition from a broader perspective.

Autism spectrum disorder (ASD) is a neurodevelopmental disease characterized by social disorder and stereotypical behaviors with an increasing incidence. ASD patients are suffering from varying degrees of mental retardation and language development abnormalities. Magnetic resonance imaging (MRI) is a noninvasive imaging technology to detect brain structural and functional dysfunction in vivo, playing an important role in the early diagnosisbasic research of ASD. High-field, small-animal MRI in basic research of autism model mice has provided a new approach to research the pathogenesis, characteristics, and intervention efficacy in autism. This article reviews MRI studies of mouse models of autism over the past 20 years. Reduced gray matter, abnormal connections of brain networks, and abnormal development of white matter fibers have been demonstrated in these studies, which are present in different proportions in the various mouse models. This provides a more macroscopic view for subsequent research on autism model mice.
