This open access book looks at how a democracy can devolve into a post-factual state. The media is being flooded by populist narratives, fake news, conspiracy theories and make-believe. Misinformation is turning into a challenge for all of us, whether politicians, journalists, or citizens. In the age of information, attention is a prime asset and may be converted into money, power, and influence – sometimes at the cost of facts. The point is to obtain exposure on the air and (...) in print media, and to generate traffic on social media platforms. With information in abundance and attention scarce, the competition is ever fiercer with truth all too often becoming the first victim. Reality Lost: Markets of Attention, Misinformation and Manipulation is an analysis by philosophers Vincent F. Hendricks and Mads Vestergaard of the nuts and bolts of the information market, the attention economy and media eco-system which may pave way to postfactual democracy. Here misleading narratives become the basis for political opinion formation, debate, and legislation. To curb this development and the threat it poses to democratic deliberation, political self-determination and freedom, it is necessary that we first grasp the mechanisms and structural conditions that cause it.

Attention deficit hyperactivity disorder affects children, adolescents, and adults. Research suggests ADHD has a heritable component. The present article presents and assesses several genetic animal models of ADHD. The paper reviews the literature involving the following genetic animal models of ADHD: the spontaneously hypertensive rat ; the Wistar–Kyoto hyperactive rat; the coloboma mouse; the fast kindling rat; the acallosal mouse; the whirler mouse; and the genetically hypertensive rat. Research investigating animal models of ADHD has concentrated on hyperactivity, but impulsiveness, (...) learning, and attention are also being examined. The use of animal models allows for the control of possibly confounding variables and has proven very useful in the screening of new therapies. These models have not been shown to be the equivalent of the human disorder, and no model encompasses all of the symptoms of the human disorder, but they are useful nevertheless. (shrink)

Developmental Coordination Disorder and Attention-Deficit/Hyperactivity Disorder are unique neurodevelopmental disorders with overlaps in executive functions and motor control. The conditions co-occur in up to 50% of cases, raising questions of the pathological mechanisms of DCD versus ADHD. Few studies have examined these overlaps in adults with DCD and/or ADHD. Therefore, to provide insights about executive functions and motor control between adults with DCD, ADHD, both conditions, or typically developed controls, this study used a stop-signal task and parallel EEG measurement. (...) We assessed executive performance via go accuracy and go reaction time, as well as motor response inhibition via stop-signal reaction time. This was complemented with analysis of event-related potentials. Based on existing investigations of adults with DCD or ADHD, we expected groups would not differ in behavioral performance on stop and go trials, but differences in ERPs, particularly in components N200 and P300 would be evident. The sample included N = 50 adults with DCD, ADHD, DCD + ADHD, and control participants. We replicated that there were no between-group differences for behavioral-level executive performance and motor response inhibition. However, on a physiological level, ERP components N200 and P300 differed between groups, particularly during successful response inhibition. These ERPs reflect potential endophenotypic differences not evident in overt behavior of participants with ADHD and/or DCD. This suggests a disorder specific employment of inhibition or general executive functions in groups of adults with DCD, DCD + ADHD, ADHD, or control participants. (shrink)

What precisely does a distraction threaten? An agent who spends an inordinate amount of time attending to her smartphone – what precisely is she lacking? I argue that whereas agency of attention is the agent’s non-automatic decision-making on what she currently pays attention to, autonomy of attention is the agent, through her second-order desires, effectively interfering with her non-automatic decision-making on what she currently pays attention to. Freedom of attention is the agent’s possibility to hold (...) or switch her focus of attention without fixating on any specific focus against her will or without distraction from chosen foci. This conceptual work provides resources to track manipulations that diminish a person’s freedom of attention. (shrink)

This investigation addresses the hypothesis that negative affect is associated with decreased ability to shift attention to a new focus. Thirty-nine participants completed a covert attentional orienting task and then viewed a distressing film clip. Mood was measured by self-report at the beginning and end of the session. Correlations between attentional orienting performance and self-reported mood indicated that participants with greater response time costs on invalidly cued trials reported more negative affect in response to the film. These results support (...) the hypothesis that negative affect is associated with a slowness to disengage attention. (shrink)

have recently provided a compelling demonstration of enhanced attentional control under post-hypnotic suggestion. Using the classic color-word interference paradigm, in which the task is to ignore a word and to name the color in which it is printed (e.g., RED in green, say ''green''), they gave a post-hypnotic instruction to participants that they would be unable to read. This eliminated Stroop interference in high suggestibility participants but did not alter interference in low suggestibility participants. replicated this pattern and further demonstrated (...) that it is not due to a visual strategy (such as blurring or looking at a different location). As a historical footnote, we describe a ''case study'' from 18 years ago in which we observed the same result using a hypnotic instruction to a single highly suggestible individual that he could not read. The elimination of Stroop interference has important implications for both the study of attention and the study of hypnosis. (shrink)

A long history of research has revealed many neurophysiological changes and concomitant behavioral impacts of sleep deprivation, sleep restriction, and circadian rhythms. Little research, however, has been conducted in the area of computational cognitive modeling to understand the information processing mechanisms through which neurobehavioral factors operate to produce degradations in human performance. Our approach to understanding this relationship is to link predictions of overall cognitive functioning, or alertness, from existing biomathematical models to information processing parameters in a cognitive architecture, leveraging (...) the strengths from each to develop a more comprehensive explanation. The integration of these methodologies is used to account for changes in human performance on a sustained attention task across 88 h of total sleep deprivation. The integrated model captures changes due to time awake and circadian rhythms, and it also provides an account for underlying changes in the cognitive processes that give rise to those effects. The results show the potential for developing mechanistic accounts of how fatigue impacts cognition, and they illustrate the increased explanatory power that is possible by combining theoretical insights from multiple methodologies.
