Transfer of statistical learning from speech perception to production generalizes to reading
Past research has shown that short-term exposure to speech carrying certain acoustic statistics transfers robustly to speech production. However, all studies reporting such transfer have used auditory repetition tasks. Therefore, it is unclear whether perception-production transfer in the acoustic-phonetic domain extends to tasks without an auditory model to probe production. We answer this question in two experiments. Experiment 1 shows that peo…
Exposure to an accent transfers to speech production in a single shot
Bears don’t always mess with beers: Limits on generalization of statistical learning in speech
Perception changes rapidly and implicitly as a function of passive exposure to speech that samples different acoustic distributions. Past research has shown that this statistical learning generalizes across talkers and, to some extent, new items, but these studies involved listeners’ active engagement in processing statistics-bearing stimuli. In this study, we manipulated the relationship between voice onset time (VOT) and fundamental frequency (…
Incidental Nonspeech Auditory Learning Scaffolds Phonetic, Category, and Word Learning in a Foreign Language Classroom
There is considerable lab-based evidence for successful incidental learning, in which a learner's attention is directed away from the to-be-learned stimulus and towards another stimulus. In this study, we extend incidental learning research into the language learning classroom. Three groups of adult second language (L2) learners (N = 52) engaged in structured classroom Mandarin learning took part in an 8-week study. One group served as a classroo…

The Perception of Color
This chapter explains the mechanisms underlying color perception, starting with the basic principles where color arises from the interaction between light wavelengths and the nervous system.

Hearing in the Environment
This chapter explores how the auditory system enables humans to interpret complex acoustic environments. It examines sound localization through cues such as interaural time difference and interaural level differences, which give a sense of spatial awareness despite the complexity of overlapping sound waves.

Midlevel vision a…
Space Perception and Binocular Vision
This chapter explores the mechanisms behind our perception of three-dimensional space, beginning with monocular cues such as occlusion, size, and perspective, which allow depth inference from single-eye input.

The chapter then examines the role of binocular vision and stereopsis, highlightin…
Informational masking influences segmental and suprasegmental speech categorization
Auditory categorization requires listeners to integrate acoustic information from multiple dimensions. Attentional theories suggest that acoustic dimensions that are informative attract attention and therefore receive greater perceptual weight during categorization. However, the acoustic environment is often noisy, with multiple sound sources competing for listeners’ attention. Amid these adverse conditions, attentional theories predict that list…
Transfer of statistical learning from passive speech perception to speech production
Communicating with a speaker with a different accent can affect one’s own speech. Despite the strength of evidence for perception-production transfer in speech, the nature of transfer has remained elusive, with variable results regarding the acoustic properties that transfer between speakers and the characteristics of the speakers who exhibit transfer. The current study investigates perception-production transfer through the lens of statistical l…
Sensation & Perception
Sensation and Perception , which is now in its seventh edition, introduces readers to the world of human senses and helps answer such interesting questions as: “Why do some substances taste sweet?” or “Why does music sound musical?” The chapters consider fundamental questions about the human senses and the impact that answers to those questions have on medical and societal issues. Presenting a balanced blend of neuroscience and cognitive psycholo…
Short-term perceptual reweighting in suprasegmental categorization
Segmental speech units such as phonemes are described as multidimensional categories whose perception involves contributions from multiple acoustic input dimensions, and the relative perceptual weights of these dimensions respond dynamically to context. For example, when speech is altered to create an “accent” in which two acoustic dimensions are correlated in a manner opposite that of long-term experience, the dimension that carries less percept…
Statistical learning across passive listening adjusts perceptual weights of speech input dimensions
Statistical learning across passive exposure has been theoretically situated with unsupervised learning. However, when input statistics accumulate over established representations - like speech syllables, for example - there is the possibility that prediction derived from activation of rich, existing representations may support error-driven learning. Here, across five experiments, we present evidence for error-driven learning across passive speec…
Auditory category learning is robust across training regimes
Multiple lines of research have developed training approaches that foster category learning, with important translational implications for education. Increasing exemplar variability, blocking or interleaving by category-relevant dimension, and providing explicit instructions about diagnostic dimensions each have been shown to facilitate category learning and/or generalization. However, laboratory research often must distill the character of natur…
Speech Perception
Cue weighting in auditory categorization: Implications for first and second language acquisition
The ability to integrate and weight information across dimensions is central to perception and is particularly important for speech categorization. The present experiments investigate cue weighting by training participants to categorize sounds drawn from a two-dimensional acoustic space defined by the center frequency (CF) and modulation frequency (MF) of frequency-modulated sine waves. These dimensions were psychophysically matched to be equally…
Predicting native English-like performance by native Japanese speakers
Phonetic category recalibration: What are the categories
Nevertheless, it persists: Dimension-based statistical learning and normalization of speech impact different levels of perceptual processing
Speech is notoriously variable, with no simple mapping from acoustics to linguistically-meaningful units like words and phonemes. Empirical research on this theoretically central issue establishes at least two classes of perceptual phenomena that accommodate acoustic variability: normalization and perceptual learning. Intriguingly, perceptual learning is supported by learning across acoustic variability, but normalization is thought to counteract…
Speech Perception
Long-term priors constrain category learning in the context of short-term statistical regularities
A neural network model of the effect of prior experience with regularities on subsequent category learning
Categories are often structured by the similarities of instances within the category defined across dimensions or features. Researchers typically assume that there is a direct, linear relationship between the physical input dimensions across which category exemplars are defined and the psychological representation of these dimensions. However, this assumption is not always warranted. Through a set of simulations, we demonstrate that the psycholog…
