This work provides a procedure and methodology for the design of an electro-magnetic sensor based on induction due to ferromagnetic and pure electrically conduc-tive hidden targets. The electromagnetic sensor is made of one or several excitation coils, whi ...
Observers discriminated the numerical proportion of two sets of elements (N = 9, 13, 33, and 65) that differed either by color or orientation. According to the standard Thurstonian approach, the accuracy of proportion discrimination is determined by irredu ...
Even in the absence of neurodegenerative disease, aging strongly affects vision. Whereas optical deficits are well documented, much less is known perceptual deficits. In most perceptual studies, one paradigm is tested and it is usually found that older par ...
In real-life situations, we are often required to recognize our own movements among movements originating from other people. In social situations, these movements are often correlated (for example, when dancing or walking with others) adding considerable d ...
The ability to make judgments about a peripheral target stimulus can be impaired when the target is surrounded by flanking stimuli. This effect is called crowding. Crowding is often related to relatively simple low-level mechanisms that pool visual informa ...

In crowding, neighbouring elements impair the perception of a target. Crowding is often considered a consequence of spatial pooling of visual information. We investigated the role of configural effects in crowding by manipulating the global stimulus config ...
To reveal the mechanisms of spatial interference in the fovea, we examined the capacity of a variety of lateral flanking configurations to interfere with alignment thresholds of a vertical vernier. A single line on each side of the vernier, at the optimal ...
