The Impact and Status of Carol Fowler's Supramodal Theory of Multisensory Speech Perception

ABSTRACT

One important contribution of Carol Fowler's direct approach to speech perception is its account of multisensory perception. This supramodal account proposes a speech function that detects supramodal information available across audition, vision, and touch. This detection allows for the recovery of articulatory primitives that provide the basis of a common currency shared between modalities as well as between perception and production. Common currency allows for perceptual experience to be shared between modalities and supports perceptually guided speaking as well as production-guided perception. In this report, we discuss the contribution and status of the supramodal approach relative to recent research in multisensory speech perception. We argue that the approach has helped motivate a multisensory revolution in perceptual psychology. We then review the new behavioral and neurophysiological research on (a) supramodal information, (b) cross-sensory sharing of experience, and (c) perceptually guided speaking as well as production guided speech perception. We conclude that Fowler's supramodal theory has fared quite well in light of this research.     

Values and Science: An Argument for Why They Cannot Be Separated

A distinction between facts and values is often assumed when people in the modern West talk about science. The biologist Stephen Gould, for example, famously argued that religion covers questions of meaning and moral value, but science deals with empirical facts. This paper challenges the traditional fact/value distinction by questioning the presuppositions about science upon which it depends. It begins by describing the origins of the fact/value distinction in the Scientific Revolution and then gives three reasons for the inseparability of facts and values in scientific inquiry, drawing upon themes from the “practice turn” in recent scholarship on the sciences.     

Racial Attitudes Predicted Changes in Ostensibly Race‐Neutral Political Attitudes Under the Obama Administration

Past research demonstrated that racial prejudice played a significant role in the 2008 presidential election, but relatively less is known about the relationship between prejudice and public opinion throughout the Obama administration. In the present research, we examined not only whether racial attitudes were associated with evaluations of Mr. Obama and his administration, but also whether they may have influenced the development of more general political attitudes during the early years of the Obama administration. We investigated this question using panel data from a nationally representative sample of Americans interviewed between September 2008 and July 2010. Racial attitudes measured prior to the election predicted early disapproval of President Obama's handling of important issues. Early disapproval of President Obama's performance, in turn, predicted later perceptions of whether the state of the nation was improving. Further, the divergence between high‐prejudice and low‐prejudice individuals in their perceptions of the state of the nation became greater over time, consistent with the idea that racial attitudes were more powerfully expressed in political judgments as time passed.     

For the Win: Risk‐Sensitive Decision‐Making in Teams

Risk‐sensitivity theory predicts that decision‐makers should prefer high‐risk options in high need situations when low‐risk options will not meet these needs. Recent attempts to adopt risk‐sensitivity as a framework for understanding human decision‐making have been promising. However, this research has focused on individual‐level decision‐making, has not examined behavior in naturalistic settings, and has not examined the influence of multiple levels of need on decision‐making under risk. We examined group‐level risk‐sensitive decision‐making in two American football leagues: the National Football League (NFL) and the National College Athletic Association (NCAA) Division I. Play decisions from the 2012 NFL (Study 1; N = 33 944), 2013 NFL (Study 2; N = 34 087), and 2012 NCAA (Study 3; N = 15 250) regular seasons were analyzed. Results demonstrate that teams made risk‐sensitive decisions based on two distinct needs: attaining first downs (a key proximate goal in football) and acquiring points above parity. Evidence for risk‐sensitive decisions was particularly strong when motivational needs were most salient. These findings are the first empirical demonstration of team risk‐sensitivity in a naturalistic organizational setting. Copyright © 2016 John Wiley & Sons, Ltd.     

On the dissociation between reaction time and response duration as a function of lexical and sublexical reading: An examination of phonetic decoding and computational models

Neurobiological models of reading account for two ways in which orthography is converted to phonology: (1) familiar words, particularly those with exceptional spelling-sound mappings (e.g., shoe) access their whole-word lexical representations in the ventral visual stream, and (2) orthographically unfamiliar words, particularly those with regular spelling-sound mappings (i.e., pseudohomophones [PHs], which are orthographically novel but sound like real words; e.g., shue) are phonetically decoded via sublexical processing in the dorsal visual stream. The present study used a naming task in order to compare naming reaction time (RT) and response duration (RD) of exception and regular words to their PH counterparts. We replicated our earlier findings with words, and extended them to PH phonetic decoding by showing a similar effect on RT and RD of matched PHs. Given that the shorter RDs for exception words can be attributed to the benefit of whole-word processing in the orthographic word system, and the longer RTs for exception words to the conflict with phonetic decoding, our PH results demonstrate that phonetic decoding also involves top-down feedback from phonological lexical representations (e.g., activated by shue) to the orthographic representations of the corresponding correct word (e.g., shoe). Two computational models were tested for their ability to account for these effects: the DRC and the CDP+. The CDP+ fared best as it was capable of simulating both the regularity and stimulus type effect on RT for both word and PH identification, although not their over-additive interaction. Our results demonstrate that both lexical reading and phonetic decoding elicit a regularity dissociation between RT and RD that provides important constraints to all models of reading, and that phonetic decoding results in top-down feedback that bolsters the orthographic lexical reading process.     

CCTV on trial: Matching video images with the defendant in the dock

The experiments reported in this paper investigated simultaneous identity matching of unfamiliar people physically present in person with moving video images typical of that captured by closed circuit television (CCTV). This simulates the decision faced by a jury in court when the identity of somebody caught on CCTV is disputed. Namely, ‘is the defendant in the dock the person depicted in video’? In Experiment 1, the videos depicted medium‐range views of a number of actor ‘culprits’. Experiment 2 used similar quality images taken a year previously, some of which showed the culprits in disguise. Experiment 3 utilised high‐quality close‐up video images. It was consistently found that in both culprit‐present and culprit‐absent videos and in optimal conditions, matching the identity of a person in video can be highly susceptible to error.

Correcting errors in eye-position data arising from the distortion of magnetic fields by display devices

Eye-position recordings have been used to produce detailed information about sampling and search behavior. The melding of magnetic head-tracking technology with eye-tracking systems has allowed for freer head movement, but not without problems. Although the requisite calibrations made before and after a reading might indicate good eye-tracking accuracy, point-of-gaze errors can occur if the reader leans toward a display, such as a film alternator. The error results from the characteristic that large metal masses can distort magnetic fields, leading to false magnetic sensor data. Corrections for this type of error have involved mapping the exact location and orientation of the magnetic sensor in the magnetic field by using a precision positioning device. We have devised a much cheaper method that relies on a fixture that holds the magnetic sensor in identical positions, with and without the distorting effect.     

Forensic neuropsychiatric evaluation of a personal injury case

Civil litigation involving the forensic neuropsychiatric evaluation of a personal injury case requires an assessment of damages and causation. The expert witness is obliged to integrate data from three critical sources of information: the review of records; the results of neuropsychological testing; and the findings from the clinical examination. In civil litigation involving a personal injury claim, the expert witness can be expected to address causation and prognosis of any neuropsychiatric damages. We discuss the undertaking of a forensic neuropsychiatric evaluation, psychiatric disorders often encountered in personal injury litigation, provide case vignettes and describe a number of special types of forensic neuropsychiatric evaluations, for example, Workers' Compensation, VA Disability and Social Security Disability.     

Conceptual Conservatism and Contingent Composition

This paper proposes a novel answer to the Special Composition Question. In some respects it agrees with brutalism about composition; in others with universalism. The main novel feature of this answer is the insight I think it gives into what the debate over the Special Composition Question is about.
