COMMON AND DISTINCT NEURAL CORRELATES OF SOCIAL INTERACTION PERCEPTION AND THEORY OF MIND Open
Social interaction perception and theory of mind (ToM) frequently co-occur, but their commonalities and distinctions at behavioral and neural levels remain unclear. Participants ( N = 231) provided moment-by-moment ratings of four text and…

Image Processing in the Acute to Chronic Pain Signatures (A2CPS) Project Open
The Acute to Chronic Pain Signatures (A2CPS) project is a large-scale, multi-site initiative aimed at identifying biomarkers and biosignatures that predict the transition from acute to chronic pain. The project is collecting multimodal, lo…

Comparing automated subcortical volume estimation methods; amygdala volumes estimated by <span>FSL</span> and <span>FreeSurfer</span> have poor consistency Open
Subcortical volumes are a promising source of biomarkers and features in biosignatures, and automated methods facilitate extracting them in large, phenotypically rich datasets. However, while extensive research has verified that the automa…

From Maps to Models: A Survey on the Reliability of Small Studies of Task-Based fMRI Open
Task-based functional magnetic resonance imaging (fMRI) is a powerful tool for studying brain function. However, the reliability and viability of small-sample studies remain a concern. While it is well understood that larger samples are pr…

HeuDiConv — flexible DICOM conversion into structureddirectory layouts Open
In order to support efficient processing, data must be formatted according to standards that are prevalent in the field and widely supported among actively developed analysis tools. The Brain Imaging Data Structure (BIDS) (Gorgolewski et a…

A multimodal fMRI dataset unifying naturalistic processes with a rich array of experimental tasks Open
Cognitive neuroscience has advanced significantly due to the availability of openly shared datasets. Large sample sizes, large amounts of data per person, and diversity in tasks and data types are all desirable, but are difficult to achiev…

The push-pull of serial dependence effects: Every response is both an attraction to the prior response and a repulsion from the prior stimulus Open
In the “serial dependence” effect, responses to visual stimuli appear biased toward the last trial’s stimulus. Fischer and Whitney (2014) proposed that this reflects a “continuity field” that promotes visual stability by biasing perception…

Visual Recollection for Non-Declarative Representations Open
Recollection is a pattern completion process that enables retrieval of arbitrarily associated information following minimal study. These attributes enable recollection to support retrieval of many kinds of mnemonic representations, from hi…

A modeling framework for determining modulation of neural-level tuning from non-invasive human fMRI data Open
Many neuroscience theories assume that tuning modulation of individual neurons underlies changes in human cognition. However, non-invasive fMRI lacks sufficient resolution to visualize this modulation. To address this limitation, we develo…

The Push-pull of Serial Dependence Effects: Attraction to the Prior Response and Repulsion from the Prior Stimulus Open
In the “serial dependence” effect, responses to visual stimuli appear biased toward the last trial’s stimulus. However, several kinds of serial dependence exist, with some reflecting prior stimuli and others reflecting prior responses. One…

Uncovering the Neural and Behavioral Factors That Underlie Changes in Processing Visual Orientation Open
From moment to moment, the visual environment appears stable; despite prolonged scrutiny, the edge of a desk is not perceived to change. But this apparent stability emerges from perceptual and decisional systems that undergo continuous mod…

Bayesian modeling of fMRI data to infer modulation of neural tuning functions in visual cortex Open
Many visual neurons exhibit tuning functions for stimulus features such as orientation. Methods for analyzing fMRI data reveal analogous feature-tuning in the BOLD signal (e.g., Inverted Encoding Models; Brouwer and Heeger, 2009). Because …

A Roadmap for Understanding Memory: Decomposing Cognitive Processes into Operations and Representations Open
Thanks to patients Phineas Gage and Henry Molaison, we have long known that behavioral control depends on the frontal lobes, whereas declarative memory depends on the medial temporal lobes (MTL). For decades, cognitive functions—behavioral…

Connecting the dots without top-down knowledge: Evidence for rapidly-learned low-level associations that are independent of object identity. Open
Knowing the identity of an object can powerfully alter perception. Visual demonstrations of this-such as Gregory's (1970) hidden Dalmatian-affirm the existence of both top-down and bottom-up processing. We consider a third processing pathw…

Implicit visual recollection: Connecting the dots without top-down knowledge Open
Discovering the Mooney-style Dalmatian dog against its dappled black and white background for the first time enables an observer to rapidly identify the Dalmatian on subsequent occasions. This effect of prior exposure has been explained wi…

A hierarchical Bayesian model for inferring neural tuning functions from voxel tuning functions Open
It is tempting to infer the behavior of individual neurons from the behavior of individual voxels in an fMRI experiment. For instance, voxel tuning functions (VTFs) measure the magnitude of the BOLD response to a range of stimulus features…

A hierarchical Bayesian state trace analysis for assessing monotonicity while factoring out subject, item, and trial level dependencies Open
Traditional state trace analyses assess the latent dimensionality of a cognitive process by asking whether the means of two dependent variables conform to a monotonic function across a set of conditions. Recently proposed methods test whet…

A Computational Model of Perceptual and Mnemonic Deficits in Medial Temporal Lobe Amnesia Open
Damage to the Medial Temporal Lobe (MTL) has long been known to impair declarative memory and recent evidence suggests that it also impairs visual perception. A theory termed the representational-hierarchical account explains such impairme…
