Breaking the Circularity in Circular Analyses: Simulations and Formal Treatment of the Flattened Average Approach (2020)
Journal Article

There has been considerable debate and concern as to whether there is a replication crisis in the scientific literature. A likely cause of poor replication is the multiple comparisons problem. An important way in which this problem can manifest in th... Read More about Breaking the Circularity in Circular Analyses: Simulations and Formal Treatment of the Flattened Average Approach.

Response Dependence of Reversal Related ERP Components in Perception of Ambiguous Figures (2020)
Journal Article

Perceptual multi-stability is characterised by alternating interpretations of an unchanging stimulus input. The reversal negativity (RN) and reversal positivity (RP) ERP components show differences in electrophysiological responses between trials on...

Theta Phase-Dependent Modulation of Perception by Concurrent tACS and Periodic Visual Stimulation (2020)
Journal Article

Sensory perception can be modulated by the phase of neural oscillations, especially in the theta and alpha ranges. Oscillatory activity in the visual cortex can be entrained by transcranial alternating current stimulation (tACS) as well as periodic v...

Evidence for view-invariant face recognition units in unfamiliar face learning (2017)
Journal Article

Many models of face recognition incorporate the idea of a face recognition unit (FRU), an abstracted representation formed from each experience of a face which aids recognition under novel viewing conditions. Some previous studies have failed to find... Read More about Evidence for view-invariant face recognition units in unfamiliar face learning.

Data-driven region-of-interest selection without inflating Type I error rate (2017)
Journal Article

In ERP and other large multidimensional neuroscience data sets, researchers often select regions of interest (ROIs) for analysis. The method of ROI selection can critically affect the conclusions of a study by causing the researcher to miss effects i...

Causal evidence that intrinsic beta frequency is relevant for enhanced signal propagation in the motor system as shown through rhythmic TMS (2015)
Journal Article

Correlative evidence provides support for the idea that brain oscillations underpin neural computations. Recent work using rhythmic stimulation techniques in humans provide causal evidence but the interactions of these external signals with intrinsic...

Training-induced recovery of low-level vision followed by mid-level perceptual improvements in developmental object and face agnosia (2014)
Journal Article

Long-term deprivation of normal visual inputs can cause perceptual impairments at various levels of visual function, from basic visual acuity deficits, through mid-level deficits such as contour integration and motion coherence, to high-level face an...

Counterbalancing for Serial Order Carryover Effects in Experimental Condition Orders (2012)
Journal Article

Reactions of neural, psychological, and social systems are rarely, if ever, independent of previous inputs and states. The potential for serial order carryover effects from one condition to the next in a sequence of experimental trials makes counterb...

Preserved local but disrupted contextual figure-ground influences in an individual with abnormal function of intermediate visual areas (2012)
Journal Article

Visual perception depends not only on local stimulus features but also on their relationship to the surrounding stimulus context, as evident in both local and contextual influences on figure-ground segmentation. Intermediate visual areas may play a r... Read More about Preserved local but disrupted contextual figure-ground influences in an individual with abnormal function of intermediate visual areas.

Cue Competition Affects Temporal Dynamics of Edge-assignment in Human Visual Cortex (2011)
Journal Article

Edge-assignment determines the perception of relative depth across an edge and the shape of the closer side. Many cues determine edge-assignment, but relatively little is known about the neural mechanisms involved in combining these cues. Here, we ma...

Grouping puts figure-ground assignment in context by constraining propagation of edge assignment (2010)
Journal Article

Figure-ground organization involves the assignment of edges to a figural shape on one or the other side of each dividing edge. Established visual cues for edge assignment primarily concern relatively local rather than contextual factors. In the prese...

Multivariate decoding of EEG data reveals similar mechanisms mediate perceptual adaptation and spontaneous perceptual reversals
Presentation / Conference

The cause of spontaneous perceptual reversals of visually ambiguous stimuli (e.g., Rubin’s faces-vase) has been attributed to several different mechanisms. One hypothesis suggests that adaptation, or “neural fatigue”, builds up while one interpretati...
