Fixations

This book provides the first comprehensive overview of the various conventional and cutting-edge surgical techniques for stapes fixations. After describing the broad range of stapes fixations, it discusses the preoperative diagnostic workup, with special emphasis on the role of CT scanning. It reviews stapedectomy and stapedotomy via the classic tympanotomy approach using different stapes footplate fenestration methodologies, and describes the increasingly popular technique of middle ear endoscopy. A subsequent chapter is devoted to the important topic of robot-assisted surgery. The book then reviews the evolution of the piston prosthesis, highlighting the practical aspects of the different types of piston, their benefits, and their impact on hearing. Lasers are also discussed, and the closing chapters focus on revision surgery and consider outcome measures following stapes surgery. To better illustrate the subject matter, the book features a wealth of photographs (including more than 50 in color), as well as in-depth surgical videos.

At the core of the many debates throughout cognitive science concerning how decisions are made are the processes governing the time course of preference formation and decision. From perceptual choices, such as whether the signal on a radar screen indicates an enemy missile or a spot on a CT scan indicates a tumor, to cognitive value-based decisions, such as selecting an agreeable flatmate or deciding the guilt of a defendant, significant and everyday decisions are dynamic over time. Phenomena such as decoy effects, preference reversals and order effects are still puzzling researchers. For example, in a legal context, jurors receive discrete pieces of evidence in sequence, and must integrate these pieces together to reach a singular verdict. From a standard Bayesian viewpoint the order in which people receive the evidence should not influence their final decision, and yet order effects seem a robust empirical phenomena in many decision contexts. Current research on how decisions unfold, especially in a dynamic environment, is advancing our theoretical understanding of decision making. This Research Topic aims to review and further explore the time course of a decision - from how prior beliefs are formed to how those beliefs are used and updated over time, towards the formation of preferences and choices and post-decision processes and effects. Research literatures encompassing varied approaches to the time-scale of decisions will be brought into scope: a) Speeded decisions (and post-decision processes) that require the accumulation of noisy and possibly non-stationary perceptual evidence (e.g., randomly moving dots stimuli), within a few seconds, with or without temporal uncertainty. b) Temporally-extended, value-based decisions that integrate feedback values (e.g., gambling machines) and internally-generated decision criteria (e.g., when one switches attention, selectively, between the various aspects of several choice alternatives). c) Temporally extended, belief-based decisions that build on the integration of evidence, which interacts with the decision maker's belief system, towards the updating of the beliefs and the formation of judgments and preferences (as in the legal context). Research that emphasizes theoretical concerns (including optimality analysis) and mechanisms underlying the decision process, both neural and cognitive, is presented, as well as research that combines experimental and computational levels of analysis.

Addressing a rapidly growing interest in second language research, this hands-on text provides students and researchers with the means to understand and use current methods in psycholinguistics. With a focus on the actual methods, designs, and techniques used in psycholinguistics research as they are applied to second language learners, this book offers the practical guidance readers need to determine which method is the best for what they wish to investigate as well as the tools that will enhance their research. Each methods chapter is written by a leading expert who describes, discusses, and comments on how a method is used and what its strengths and limitations are for second language research. These chapters follow a specific format to ensure cohesion and a predictable structure across all chapters. The chapters also inform the novice researcher on such key issues as ease of use, costs, potential pitfalls, and other related matters, each of which impact decisions that researchers make about the paths they take. With the most reliable information available from experienced reseachers, Research Methods in Second Language Psycholinguistics is an essential resource for anyone interested in conducting second language reserach using psycholinguistic methods.
