Motor Selection Dynamics in FEF Explain the Reaction Time Variance of Saccades to Single Targets
RESEARCH ARTICLE Motor selection dynamics in FEF explain the reaction time variance of saccades to single targets Christopher K Hauser, Dantong Zhu, Terrence R Stanford, Emilio Salinas* Department of Neurobiology and Anatomy, Wake Forest School of Medicine, Winston-Salem, United States Abstract In studies of voluntary movement, a most elemental quantity is the reaction time (RT) between the onset of a visual stimulus and a saccade toward it. However, this RT demonstrates extremely high variability which, in spite of extensive research, remains unexplained. It is well established that, when a visual target appears, oculomotor activity gradually builds up until a critical level is reached, at which point a saccade is triggered. Here, based on computational work and single-neuron recordings from monkey frontal eye field (FEF), we show that this rise-to- threshold process starts from a dynamic initial state that already contains other incipient, internally driven motor plans, which compete with the target-driven activity to varying degrees. The ensuing conflict resolution process, which manifests in subtle covariations between baseline activity, build- up rate, and threshold, consists of fundamentally deterministic interactions, and explains the observed RT distributions while invoking only a small amount of intrinsic randomness. DOI: https://doi.org/10.7554/eLife.33456.001 Introduction The reaction time (RT) represents the total time taken to perform all of the mental operations that may contribute to a particular action, such as stimulus detection, attention, working memory, or motor preparation. Although the importance of the RT as a fundamental metric for inferring the *For correspondence: mechanisms that mediate cognition cannot be overstated (Welford, 1980; Meyer et al., 1988), [email protected] such reliance is a double-edged sword. -
Timing Accuracy of Web Applications on Touchscreen and Keyboard Devices
Behavior Research Methods https://doi.org/10.3758/s13428-019-01321-2 Mental chronometry in the pocket? Timing accuracy of web applications on touchscreen and keyboard devices Thomas Pronk1,2 & Reinout W. Wiers1 & Bert Molenkamp1,2 & Jaap Murre1 # The Author(s) 2020 Abstract Web applications can implement procedures for studying the speed of mental processes (mental chronometry) and can be administered via web browsers on most commodity desktops, laptops, smartphones, and tablets. This approach to conducting mental chronometry offers various opportunities, such as increased scale, ease of data collection, and access to specific samples. However, validity and reliability may be threatened by less accurate timing than specialized software and hardware can offer. We examined how accurately web applications time stimuli and register response times (RTs) on commodity touchscreen and keyboard devices running a range of popular web browsers. Additionally, we explored the accuracy of a range of technical innovations for timing stimuli, presenting stimuli, and estimating stimulus duration. The results offer some guidelines as to what methods may be most accurate and what mental chronometry paradigms may suitably be administered via web applications. In controlled circumstances, as can be realized in a lab setting, very accurate stimulus timing and moderately accurate RT mea- surements could be achieved on both touchscreen and keyboard devices, though RTs were consistently overestimated. In uncontrolled circumstances, such as researchers may encounter online, stimulus presentation may be less accurate, especially when brief durations are requested (of up to 100 ms). Differences in RT overestimation between devices might not substantially affect the reliability with which group differences can be found, but they may affect reliability for individual differences. -

A Neural Network Framework for Cognitive Bias
fpsyg-09-01561 August 31, 2018 Time: 17:34 # 1 HYPOTHESIS AND THEORY published: 03 September 2018 doi: 10.3389/fpsyg.2018.01561 A Neural Network Framework for Cognitive Bias Johan E. Korteling*, Anne-Marie Brouwer and Alexander Toet* TNO Human Factors, Soesterberg, Netherlands Human decision-making shows systematic simplifications and deviations from the tenets of rationality (‘heuristics’) that may lead to suboptimal decisional outcomes (‘cognitive biases’). There are currently three prevailing theoretical perspectives on the origin of heuristics and cognitive biases: a cognitive-psychological, an ecological and an evolutionary perspective. However, these perspectives are mainly descriptive and none of them provides an overall explanatory framework for the underlying mechanisms of cognitive biases. To enhance our understanding of cognitive heuristics and biases we propose a neural network framework for cognitive biases, which explains why our brain systematically tends to default to heuristic (‘Type 1’) decision making. We argue that many cognitive biases arise from intrinsic brain mechanisms that are fundamental for the working of biological neural networks. To substantiate our viewpoint, Edited by: we discern and explain four basic neural network principles: (1) Association, (2) Eldad Yechiam, Technion – Israel Institute Compatibility, (3) Retainment, and (4) Focus.

IDC OPINION This study represents the vendor assessment model called IDC MarketScape. This research is a quantitative and qualitative assessment of the characteristics that explain a vendor's current and future success in the digital strategy consulting services marketplace. This study assesses the capabilities and business strategies of 13 prominent digital strategy consulting services vendors. This evaluation is based on a comprehensive framework and a set of parameters expected to be most conducive to success in providing digital strategy consultancy. A significant component of this evaluation is the inclusion of digital strategy consulting buyers' perception of both the key characteristics and the capabilities of these providers. This client input was provided primarily from the vendors' clients, supplemented with a worldwide survey. Key findings include: . Consultancies are getting the basics right. Reference clients that IDC spoke with were impressed by the quality of the people from the leading digital strategy consultancies. On average, reference clients gave consultancies highest scores for people quality, action orientation, and client-specific insight. This indicates that digital strategy consultancies are getting the basics right — they are recruiting smart and empathetic people and are training and developing them well, they are getting to know their clients inside out, and they are producing very useful advice as a result. Clients want to be challenged more than ever by their digital strategy consultants. -

An electronic synapse functionalized with License 4.0 (CC BY-NC). an artificial sensory receptor and an artificial motor unit can be a fundamental element of bioinspired soft elec- tronics. Here, we report an organic optoelectronic sensorimotor synapse that uses an organic optoelectronic synapse and a neuromuscular system based on a stretchable organic nanowire synaptic transistor (s-ONWST). The voltage pulses of a self-powered photodetector triggered by optical signals drive the s-ONWST, and resultant informative synaptic outputs are used not only for optical wireless communication of human-machine interfaces but also for light-interactive actuation of an artificial muscle actuator in the same way that a biological muscle fiber contracts. Downloaded from Our organic optoelectronic sensorimotor synapse suggests a promising strategy toward developing bioinspired soft electronics, neurologically inspired robotics, and electronic prostheses.
