Background: Traditional body size estimation (BSE) tasks often lack ecological validity, relying on 2D stimuli. Advances in 3D avatar technology allow more realistic assessments, yet their neural correlates remain unclear.
Methods: In 29 healthy participants, we investigated neural correlates of the
Somatomap 3D task, where participants adjusted 2...
Background: High sensitivity to potential loss is a common
characteristic of those with obsessive-compulsive disorder (OCD)
and may be of special importance to understanding the clinical
symptoms. Convergent human neuroimaging and animal studies
suggest that the habenula is a key center for encoding the
aversive experience of loss. The habenula and...
Background: People with anorexia nervosa (AN) commonly exhibit elevated anxiety and atypical reward responsiveness. To examine multivariate neural patterns
associated with reward and the impact of anxiety on reward, we analyzed fMRI data from a monetary reward task using representational similarity analysis, a
multivariate approach that measures t...
We used the Garner paradigm to examine the relationship between the perceptual and conceptual aspects of an image for identification. Participants completed tasks that required them to selectively attend to semantic identity (e.g., manmade vs. natural) while ignoring image format, and vice versa, with the irrelevant dimension either held constant (...
People with anorexia nervosa (AN) commonly exhibit elevated anxiety and atypical reward responsiveness. To examine multivariate neural patterns associated with reward and the impact of anxiety on reward, we analyzed fMRI data from a monetary reward task using representational similarity analysis, a multivariate approach that measures trial-by-trial...
Background
Individuals with body dysmorphic disorder (BDD) perceive distortions in their appearance, which could be due to imbalances in global and local visual processing. The vertical occipital fasciculus connects dorsal and ventral visual stream regions, integrating global and local information, yet the role of this structural connection in BDD...
We present a comprehensive review of the rare syndrome visual form agnosia (VFA). We begin by documenting its history, including the origins of the term, and the first case study labelled as VFA. The defining characteristics of the syndrome, as others have previously defined it, are then described. The impairments, preserved aspects of visual perce...
Research findings on which brain areas demonstrate fMRI adaptation to the form, orientation, and size of visual stimuli has been mixed. Studies demonstrate effects in various subdivisions of the lateral occipital cortex (LOC), including retinotopically tuned areas LO-1 and LO-2, and dorsal stream areas in the intraparietal sulcus (IPS). Therefore,...
It is widely assumed that subliminal word priming is case insensitive and that a short SOA (< 100 ms) is required to observe any effects. Here we attempted to replicate results from an influential study with the inclusion of a longer SOA to re-examine these assumptions. Participants performed a semantic categorisation task on visible word targets t...
Our understanding of how form, orientation and size are processed within and outside of awareness is limited and requires further investigation. Therefore, we investigated whether or not the visual discrimination of basic object features can be influenced by subliminal processing of stimuli presented beforehand. Visual masking was used to render st...
The closer a line extends toward a surrounding frame, the longer it appears. This is known as a framing effect. Over 70 years ago, Teodor Künnapas demonstrated that the shape of the visual field itself can act as a frame to influence the perceived length of lines in the vertical-horizontal illusion. This illusion is typically created by having a ve...
