We report several experiments showing that a Gabor patch moving in apparent motion sequences appears much faster when its orientation is aligned with the motion path than when it is at an angle to it. This effect is very large and peaks at high speeds (64 degrees /s), decreases for higher and lower speeds and disappears at low speeds (4 degrees /s). This speed bias decreases as the angle betwee...

We provide novel evidence for a two-stage model of visual search applied to the selection based on top-down cues to stimulus colour and orientation. The model supposes that visual displays are first parsed into colour based groups, a process that is modulated by the presence of an initial cue to the target's colour. Subsequently search is directed to other featural properties represented within...

In this paper, we present evidence from empirical studies of human-robot interaction with different kinds of robot feedback, which suggests that speakers take their communication partners into account on the basis of partner models, which are constantly and concomitantly updated on the basis of the partner’s feedback. Thus, the partner’s contributions are not reacted to directly, but instead fe...

One of the most enduring and controversial questions in the neuroscience of sexual behaviour surrounds the mechanisms which produce sexual attraction to either males or females. Here, evidence is reviewed which supports the proposal that sexual orientation in humans may be laid down in neural circuitry during early foetal development. Behaviour genetic investigations provide strong evidence for...

We have previously reported the performance of a patient (NL) who could recognize objects, but appeared to lack knowledge of their orientation. These results were interpreted as evidence that NL had isolated access to a viewpoint-independent (ventral stream) object recognition system. However, because NL's responses on naming tasks were not timed, it was not possible to establish whether he sho...

OBJECTIVES This study assesses social workers' orientation toward the evidence-based practice (EBP) process and explores which specific variables (e.g. age) are associated. METHODS Data were collected from 341 Dutch social workers through an online survey which included a Dutch translation of the EBP Process Assessment Scale (EBPPAS), along with 13 background/demographic questions. RESULTS ...

Further evidence for global orientation processing in circular Glass patterns We recently published a paper demonstrating that concentric Glass (1969) patterns are processed by global, linear summation of concentrically organized orientation information throughout large receptive fields about 4.4° in diameter (Wilson, Wilkinson, & Asaad, 1997). Dakin and Bex (2002) have recently challenged our ...

The question of whether object recognition is orientation-invariant or orientation-dependent was investigated using a repetition blindness (RB) paradigm. In RB, the second occurrence of a repeated stimulus is less likely to be reported, compared to the occurrence of a different stimulus, if it occurs within a short time of the first presentation. This failure is usually interpreted as a difficu...
