Auditory and visual category learning in children and adults
Categories are fundamental to everyday life and the ability to learn new categories is relevant across the lifespan. Categories are ubiquitous across modalities, supporting complex processes such as object recognition and speech perception. Prior work has proposed that different categories may engage learning systems with unique developmental trajectories. There is a limited understanding of how perceptual and cognitive development influences lea…
Continuous speech tracking in bilinguals reflects adaptation to both language and noise
Principal component decomposition of acoustic and neural representations of time-varying pitch reveals adaptive efficient coding of speech covariation patterns
Arousal States as a Key Source of Variability in Speech Perception and Learning
The human brain exhibits the remarkable ability to categorize speech sounds into distinct, meaningful percepts, even in challenging tasks like learning non-native speech categories in adulthood and hearing speech in noisy listening conditions. In these scenarios, there is substantial variability in perception and behavior, both across individual listeners and individual trials. While there has been extensive work characterizing stimulus-related a…
Comparing perceptual category learning across modalities in the same individuals
Working memory relates to individual differences in speech category learning: Insights from computational modeling and pupillometry
Across two experiments, we examine the relationship between individual differences in working memory (WM) and the acquisition of non-native speech categories in adulthood. While WM is associated with individual differences in a variety of learning tasks, successful acquisition of speech categories is argued to be contingent on WM-independent procedural-learning mechanisms. Thus, the role of WM in speech category learning is unclear. In Experiment…
Neural tracking of the speech envelope is differentially modulated by attention and language experience
Cortical and Subcortical Processing of Linguistic Pitch Patterns
Pitch is one of the major prosodic cues in speech. A central research question is the way the brain derives the percept of pitch from incoming acoustic information. After introducing the functional architecture of the human auditory system, this chapter reviews lesion and neuroimaging studies and human electrophysiological studies of the processing of linguistically relevant pitch patterns at the cortical and subcortical levels, respectively. Rec…
When is a bunch of marks on paper a diagram? Diagrams as homomorphic representations
That diagrams are analog, i.e., homomorphic, representations of some kind, and sentential representations are not, is a generally held intuition. In this paper, we develop a formal framework in which the claim can be stated and examined, and certain puzzles resolved. We start by asking how physical things can represent information in some target domain. We lay a basis for investigating possible homomorphisms by modeling both the physical medium a…
Music training for the development of auditory skills
Individual variability in cue-weighting and lexical tone learning
Speech sound patterns can be discerned using multiple acoustic cues. The relative weighting of these cues is known to be language-specific. Speech-sound training in adults induces changes in cue-weighting such that relevant acoustic cues are emphasized. In the current study, the extent to which individual variability in cue weighting contributes to differential success in learning to use foreign sound patterns was examined. Sixteen English-speaki…
Analyzing Political Decision Making from an Information-Processing Perspective: Jesse
Political behavior is argued to result from interacting political and information-processing mechanisms. Political mechanisms deal with the values, interests, and influence of the political actors, while information-processing mechanisms concern themselves with the actors' use of knowledge and experience in exploring the space of choices and actions. Information-processing approaches are argued to provide a language for expressing theories of pol…
Computer-Assisted Facial Sketching
What is it about a sketch of a face, merely a few lines drawn on a piece of paper, that makes a viewer recognize them as the face of a specific person? Clearly, an artist makes a remarkable series of decisions about which aspects of a face are information-bearing for the purpose of recognition and transforms these decisions into a collection of lines. But an untrained or untalented person who desires to sketch a face is generally at a loss to kno…
