Production Mechanisms

Cognitive science has traditionally focused on mechanisms involved in high-level reasoning and problem-solving processes. Such mechanisms are often treated as autonomous from but controlling underlying physiological processes. I offer a different perspective on cognition which starts with the basic production mechanisms through which organisms construct and repair themselves and navigate their environments and then I develop a framework for conceptualizing how cognitive control mechanisms form a heterarchical network that regulates production mechanisms. Many of these control mechanisms perform cognitive tasks such as evaluating circumstances and making decisions. Cognitive control mechanisms are present in individual cells, but in metazoans, intracellular control is supplemented by a nervous system in which a multitude of neural control mechanisms are organized heterarchically. On this perspective, high-level cognitive mechanisms are not autonomous, but are elements in larger heterarchical networks. This has implications for future directions in cognitive science research.

The human brain has the impressive capacity to adapt how it processes information to high-level goals. While it is known that these cognitive control skills are malleable and can be improved through training, the underlying plasticity mechanisms are not well understood. Here, we develop and evaluate a model of how people learn when to exert cognitive control, which controlled process to use, and how much effort to exert. We derive this model from a general theory according to which the function of cognitive control is to select and configure neural pathways so as to make optimal use of finite time and limited computational resources. The central idea of our Learned Value of Control model is that people use reinforcement learning to predict the value of candidate control signals of different types and intensities based on stimulus features. This model correctly predicts the learning and transfer effects underlying the adaptive control-demanding behavior observed in an experiment on visual attention and four experiments on interference control in Stroop and Flanker paradigms. Moreover, our model explained these findings significantly better than an associative learning model and a Win-Stay Lose-Shift model. Our findings elucidate how learning and experience might shape people’s ability and propensity to adaptively control their minds and behavior. We conclude by predicting under which circumstances these learning mechanisms might lead to self-control failure.

And Behavior

Cognitive science, the attempt to provide an account of human intelligence and behavior by reference to physical “mechanisms” in the alleged neural control center of human beings, is one of the dominant philosophical projects of our time. The paper argues that Wittgenstein in para. 608 of Zettel develops an alternative to this almost universally accepted modern paradigm. However, his efforts have been widely misunderstood, in a fashion clarified by Kuhn, because scholars read competing paradigms in the light of their own cognitive science paradigm. In the present case, scholars have assumed that the words in Zettel (para. 608), especially “the center” and “chaos,” must have the same meanings that they would naturally be assigned in cognitive science. The result is, inevitably, that Zettel (para. 608) either looks like it anticipates one of the various cognitive science paradigms or it looks absurd. In opposition to this, the paper argues that the language in Zettel (para. 608) is not the language of modern cognitive science, but, rather, is the language of the emergence of order from chaos by virtue of a stabilizing center with which the Western intellectual tradition began in ancient Greek cosmology. When read against this background, it becomes clear that Zettel (para. 608) is an attempt to formulates an alternative to the cognitive science paradigm by retrieving a paradigm found in ancient Greek philosophy and literature. The idea that the brain is not the control center of the human organism is in Plato. The idea that the order in language and thought may arise out of “chaos” is prefigured in Hesiod. It is also argued that the core spirit of Wittgenstein’s later philosophy is summed up in the ancient Socratic virtue, for which there is no precise modern equivalent, of sophrosyne. The “new” alternative to the paradigms of modern cognitive science that Wittgenstein sketches in Zettel (para. 608) is rooted in ancient Greek paradigms for thinking about the cosmos - and the human microcosm.

Control Processes

Numerous studies have sought proof of whether people are genuinely honest by testing whether cognitive control mechanisms are recruited during honest and dishonest behaviors. The underlying assumption is: Deliberate behaviors require cognitive control to inhibit intuitive responses. However, cognitive control during honest and dishonest behaviors can be required for other reasons than deliberation. Across 58 neuroimaging studies (1,211 subjects), we investigated different forms of honest and dishonest behaviors and demonstrated that many brain regions previously implicated in dishonesty may reflect more general cognitive mechanisms. We argue that the motivational/volitional dimension is central to deliberation and provide evidence that motivated dishonest behaviors recruit the perigenual anterior cingulate cortex. This work questions the view that cognitive control is a hallmark of dishonesty.

Summary Although sport can promote moral values and prosocial behavior in youth, numerous research shows that sports engagement alone does not guarantee that outcome. Instead of striving for fair-play and sport excellence which not exclude justness, solidarity and moral integrity, contemporary sport frequently follows the Lombardian ethic, where „winning isn’t everything, it’s the only thing”. Moral pause or bracketed morality, as described in sport, refers to the phenomenon of tolerance and acceptance of aggressive behavior or cheating, that will be morally condemned outside sports arenas. Accordingly, lower levels of moral reasoning and behavior have been identified in athletes and non-athletes in the sports-related situation in comparison to other life situations; in athletes when compared to non-athletes, in more experienced athletes, high-level athletes, team-sport athletes, and male athletes. Moral reasoning and behavior of athletes are influenced by contextual and personal factors, with coaches having a particularly important role to play. The positive influence of sport on the moral development of athletes might be related to pre-service and in-service education of coaches how to develop adequate moral atmosphere, and how to plan for moral decision-making as an integral part of everyday practice.

Activation Phase

This review focuses on the neural control of feeding in Aplysia. Its purpose is to highlight distinctive features of the behavior and to describe their neural basis. In a number of molluscs, food is grasped by a radula that protracts, retracts, and hyperretracts. In Aplysia, however, hyperretraction can require afferent activation. Phase-dependent regulation of sensorimotor transmission occurs in this context. Aplysia also open and close the radula, generating egestive as well as ingestive responses. Thus, the feeding network multitasks. It has a modular organization, and behaviors are constructed by combinations of behavior-specific and behavior-independent neurons. When feeding is initially triggered in Aplysia, responses are poorly defined. Motor activity is not properly configured unless responses are repeatedly induced and modulatory neurotransmitters are released from inputs to the central patter generator (CPG). Persistent effects of modulation have interesting consequences for task switching.

AbstractNegation is known to have inhibitory consequences for the information under its scope. However, how it produces such effects remains poorly understood. Recently, it has been proposed that negation processing might be implemented at the neural level by the recruitment of inhibitory and cognitive control mechanisms. On this line, this manuscript offers the hypothesis that negation reuses general-domain mechanisms that subserve inhibition in other non-linguistic cognitive functions. The first two sections describe the inhibitory effects of negation on conceptual representations and its embodied effects, as well as the theoretical foundations for the reuse hypothesis. The next section describes the neurophysiological evidence that linguistic negation interacts with response inhibition, along with the suggestion that both functions share inhibitory mechanisms. Finally, the manuscript concludes that the functional relation between negation and inhibition observed at the mechanistic level could be easily integrated with predominant cognitive models of negation processing.

AbstractHumans and other primates are equipped with a foveated visual system. As a consequence, we reorient our fovea to objects and targets in the visual field that are conspicuous or that we consider relevant or worth looking at. These reorientations are achieved by means of saccadic eye movements. Where we saccade to depends on various low-level factors such as a targets’ luminance but also crucially on high-level factors like the expected reward or a targets’ relevance for perception and subsequent behavior. Here, we review recent findings how the control of saccadic eye movements is influenced by higher-level cognitive processes. We first describe the pathways by which cognitive contributions can influence the neural oculomotor circuit. Second, we summarize what saccade parameters reveal about cognitive mechanisms, particularly saccade latencies, saccade kinematics and changes in saccade gain. Finally, we review findings on what renders a saccade target valuable, as reflected in oculomotor behavior. We emphasize that foveal vision of the target after the saccade can constitute an internal reward for the visual system and that this is reflected in oculomotor dynamics that serve to quickly and accurately provide detailed foveal vision of relevant targets in the visual field.

The contents of working memory (WM) guide visual attention toward matching features, with visual search being faster when the target and a feature of an item held in WM spatially overlap (validly cued) than when they occur at different locations (invalidly cued). Recent behavioral studies have indicated that attentional capture by WM content can be modulated by cognitive control: When WM cues are reliably helpful to visual search (predictably valid), capture is enhanced, but when reliably detrimental (predictably invalid), capture is attenuated. The neural mechanisms underlying this effect are not well understood, however. Here, we leveraged the high temporal resolution of ERPs time-locked to the onset of the search display to determine how and at what processing stage cognitive control modulates the search process. We manipulated predictability by grouping trials into unpredictable (50% valid/invalid) and predictable (100% valid, 100% invalid) blocks. Behavioral results confirmed that predictability modulated WM-related capture. Comparison of ERPs to the search arrays showed that the N2pc, a posteriorly distributed signature of initial attentional orienting toward a lateralized target, was not impacted by target validity predictability. However, a longer latency, more anterior, lateralized effect—here, termed the “contralateral attention-related negativity”—was reduced under predictable conditions. This reduction interacted with validity, with substantially greater reduction for invalid than valid trials. These data suggest cognitive control over attentional capture by WM content does not affect the initial attentional-orienting process but can reduce the need to marshal later control mechanisms for processing relevant items in the visual world.

Abstract The Internet Archive curated a 90-terabyte sub-collection of captures from the US government's public website domain (‘.gov’). Such archives provide largely untapped resources for measuring attributes, behaviors and outcomes relevant to political science research. This study leverages this archive to measure a novel dimension of federal legislators' religiosity: their proportional use of religious rhetoric on official congressional websites (2006–2012). This scalable, time-variant measure improves upon more costly, time-invariant conventional approaches to measuring legislator attributes. The authors demonstrate the validity of this method for measuring legislators' public-facing religiosity and discuss the contributions and limitations of using archived Internet data for scientific analysis. This research makes three applied methodological contributions: (1) it develops a new measure for legislator religiosity, (2) it models an improved, more comprehensive approach to analyzing congressional communications and (3) it demonstrates the unprecedented potential that archived Internet data offer to researchers seeking to develop meaningful, cost-effective approaches to analyzing political phenomena.
