Infants’ perception of rhythmic patterns [PDF]

open access: yes, 2006
We explored 9-month-old infants perception of auditory temporal sequences in a series of three experiments. In Experiment 1, we presented some infants with tone sequences that were expected to induce a strongly metric framework and others with a sequence

A configural dominant account of contextual cueing : configural cues are stronger than colour cues [PDF]

open access: yes, 2013
Previous work has shown that reaction times to find a target in displays that have been repeated are faster than those for displays that have never been seen before.

Effect of Stimulus Duration on the Electrogustometric Threshold

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Electrogustometry (EGM)—the psychophysical measurement of human taste function by the application of weak electric currents to taste bud fields—has proved useful in clinical and research settings. Although EGM detection thresholds have been reported to be sensitive to stimulus duration, studies differ on this point and have not been ...

When Less Is More – Discrete Tactile Feedback Dominates Continuous Audio Biofeedback in the Integrated Percept While Controlling a Myoelectric Prosthetic Hand

open access: yesFrontiers in Neuroscience, 2019
State of the art myoelectric hand prostheses can restore some feedforward motor function to their users, but they cannot yet restore sensory feedback. It has been shown, using psychophysical tests, that multi-modal sensory feedback is readily used in the

Boundary, Brightness, and Depth Interactions During Preattentive Representation and Attentive Recognition of Figure and Ground [PDF]

open access: yes, 1993
This article applies a recent theory of 3-D biological vision, called FACADE Theory, to explain several percepts which Kanizsa pioneered. These include 3-D pop-out of an occluding form in front of an occluded form, leading to completion and recognition ...

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Craving self‐reports as outcome measures in drug addiction trials: A systematic review of ClinicalTrials.gov

open access: yesAddiction, EarlyView.
Abstract Background and Aims The subjective experience of drug craving is characterized by an overwhelming urge to consume substances. Due to strong validity and ease of use, self‐report measures are widely employed to assess substance‐related motivational dynamics.

Scene Regularity Interacts With Individual Biases to Modulate Perceptual Stability

open access: yesFrontiers in Neuroscience, 2019
Sensory input is inherently ambiguous but our brains achieve remarkable perceptual stability. Prior experience and knowledge of the statistical properties of the world are thought to play a key role in the stabilization process. Individual differences in

A Contrast/Filling-In Model of 3-D Lightness Perception [PDF]

open access: yes, 1995
Wallach's ratio hypothesis states that local luminance ratios clr!termine lightness perception under variable illumination. While local luminance ratios successfully discount gradual variations in illumination (illumination constancy or Type I constancy),

Test–retest variability of the full‐field stimulus test in patients with retinitis pigmentosa: REPEAT Study Report No. 4

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To evaluate test–retest variability (TRV) of the full‐field stimulus test (FST) in patients with retinitis pigmentosa (RP) and poor best‐corrected visual acuity (BCVA; ≤20/50 Snellen; ≥0.40 logMAR), and to assess the reliability of FST as a clinical endpoint in future RP trials.
