Conflict adaptation theory is one of the most popular theories in cognitive psychology. The theory argues that participants strategically modulate attention away from distracting stimulus features in response to conflict. Although results with proportion congruent, sequential congruency, and similar paradigms seem consistent with the conflict adaptation view, some researchers have expressed scepticism. The paradigms used in the study of conflict adaptation require the manipulation of stimulus frequencies, sequential dependencies, time-on-task regularities, and various other task regularities that introduce the potential for learning of conflict-unrelated information. This results in the unintentional confounding of measures of conflict adaptation with simpler learning and memory biases. There are also alternative accounts which propose that attentional adaptation does occur, but via different mechanisms, such as valence, expectancy, or effort. A significant (and often heated) debate remains surrounding the question of whether conflict adaptation exists independent of these alternative mechanisms of action. The aim of this Research Topic is to provide a forum for current directions in this area, considering perspectives from all sides of the debate.

A major hallmark in the adaptive control of voluntary action is the ability to anticipate short and long term future events. Anticipation in its various forms is an important prerequisite for (higher order) cognitive abilities such as planning, reasoning and the pursuit of both immediate goals and long-term goals that may even stand in opposition to immediate desires and needs (e.g., to invest in pension funds). Therefore, it is not surprising that diverse and rather independent research lines have evolved, all somehow targeting various anticipatory capacities that are involved in the control of voluntary action and thus, contribute to the uniqueness of human goal-directed behavior. For example, prediction of the incentive value of action outcomes drives goal-directed instrumental behavior (e.g., Dickinson & Balleine, 2000; Rushworth & Behrens, 2008). Similarly, the Ideo-Motor Principle assumes that actions are selected and activated by the mere anticipation of the sensory experience they produce (e.g., James, 1890; Prinz, 1990). Furthermore, the degree of match between intended, anticipated and actual action effects has been proposed to be a major determinant of motor programming and online action corrections (Jeannerod, 1981), motor learning (e.g., Wolpert, Diedrichsen, & Flanagan, 2011), and the subjective sense of causing and controlling an action and its effects (Sense of Agency; e.g., Abell, Happé, & Frith, 2000). The role of anticipation in the control of voluntary action, however, goes far beyond the anticipation of immediate action effects and desired goals. For instance, pre-cues and alerting signals are used for advance preparation of what to do (e.g., Meiran, 1996), when to act or expect an event onset (e.g., Callejas, Lupianez, & Tudela, 2004; Los & van der Heuvel, 2001; Nobre & Coull, 2010) and to anticipate conflict (e.g., Correa, Rao, & Nobre, 2009). Voluntary action is influenced by the anticipation and prediction of mental effort in task processing (e.g., Song & Schwarz, 2008). In addition, the anticipation of long-term future social consequences (e.g., expected aloneness) has been shown to affect cognitive mechanisms involved in logic and reasoning (e.g., Baumeister, Twenge, & Nuss, 2002). Last but not least, learning of statistical contingencies (e.g., conflict frequency) leads to the anticipation and prediction of context-specific executive control requirements (e.g., Crump, Gong, & Milliken, 2006, Dreisbach & Haider, 2006). The aim of the present Research Topic is to provide a platform that offers the possibility of cross-fertilization and enhanced visibility among to date rather segregated research lines.

High Performance Parallelism Pearls Volume 2 offers another set of examples that demonstrate how to leverage parallelism. Similar to Volume 1, the techniques included here explain how to use processors and coprocessors with the same programming – illustrating the most effective ways to combine Xeon Phi coprocessors with Xeon and other multicore processors. The book includes examples of successful programming efforts, drawn from across industries and domains such as biomed, genetics, finance, manufacturing, imaging, and more. Each chapter in this edited work includes detailed explanations of the programming techniques used, while showing high performance results on both Intel Xeon Phi coprocessors and multicore processors. Learn from dozens of new examples and case studies illustrating "success stories" demonstrating not just the features of Xeon-powered systems, but also how to leverage parallelism across these heterogeneous systems. - Promotes write-once, run-anywhere coding, showing how to code for high performance on multicore processors and Xeon Phi - Examples from multiple vertical domains illustrating real-world use of Xeon Phi coprocessors - Source code available for download to facilitate further exploration
