Symbol addition by monkeys provides evidence for normalized quantity coding

MS Livingstone, WW Pettine… - Proceedings of the …, 2014 - National Acad Sciences
Weber’s law can be explained either by a compressive scaling of sensory response with
stimulus magnitude or by a proportional scaling of response variability. These two mechanisms …

Laminar segregation of sensory coding and behavioral readout in macaque V4

WW Pettine, NA Steinmetz… - Proceedings of the …, 2019 - National Acad Sciences
Neurons in sensory areas of the neocortex are known to represent information both about
sensory stimuli and behavioral state, but how these 2 disparate signals are integrated across …

Cognitive mechanisms underlying prosocial decision making in callous-unemotional traits

DE Winters, WW Pettine, JT Sakai - Journal of Psychopathology and …, 2023 - Springer
Callous-unemotional (CU) traits are characterized by a lack of prosocial emotions, which has
been demonstrated with prosocial behavior paradigms. While shaping our understanding …

Human generalization of internal representations through prototype learning with goal-directed attention

WW Pettine, DV Raman, AD Redish… - Nature Human …, 2023 - nature.com
The world is overabundant with feature-rich information obscuring the latent causes of
experience. How do people approximate the complexities of the external world with simplified …

[HTML][HTML] Excitatory-inhibitory tone shapes decision strategies in a hierarchical neural network model of multi-attribute choice

WW Pettine, K Louie, JD Murray… - PLoS computational …, 2021 - journals.plos.org
We are constantly faced with decisions between alternatives defined by multiple attributes,
necessitating an evaluation and integration of different information sources. Time-varying …

Prefrontal contributions to attention and working memory

…, K Clark, Y Merrikhi, A Mueller, W Pettine… - … of visuospatial attention …, 2019 - Springer
The processes of attention and working memory are conspicuously interlinked, suggesting
that they may involve overlapping neural mechanisms. Working memory (WM) is the ability to …

Characterization of novel microelectrode geometries for detection of neurotransmitters

W Pettine, M Jibson, T Chen, S Tobet… - IEEE sensors …, 2011 - ieeexplore.ieee.org
In this paper, a microelectrode array is introduced and characterized using differential pulse
voltammetry (DPV), amperometry and fast scan cyclic voltammetry with norepinephrine as a …

[PDF][PDF] A tool for longitudinal assessment of individual differences in judgment calibration during category learning

WW Pettine, DE Winters, JD Murray, A Anticevic… - 2023 - osf.io
Accurately judging the quality of one’s estimates is a critical psychological process that
varies across individuals, fluctuates over time, and is highly domain specific. While there are …

[PDF][PDF] Human latent-state generalization through prototype learning with discriminative attention

The high-dimensional sensory environment we experience is structured by underlying
latent states1, 2. Internal representations of these latent states must generalize to new …

Hierarchical network model excitatory-inhibitory tone shapes alternative strategies for different degrees of uncertainty in multi-attribute decisions

WW Pettine, K Louie, JD Murray, XJ Wang - bioRxiv, 2020 - biorxiv.org
We investigated two-attribute, two-alternative decision-making in a hierarchical neural
network with three layers: an input layer encoding choice alternative attribute values; an …
