Introduction
Relying on her multidisciplinary background, Dr. Ziat's approach to science is holistic; her goals are to better understand perception and human interaction with the natural and artificial environment. For the last eighteen years, she have been studying haptic perception by combining engineering, cognitive psychology, human-computer interaction (HCI), and neuroscience to understand all aspects of human touch. From the moment fingers contact a surface to the time information reaches the brain, her research focusses on making sense of sensations that lead to a stable perception of the world. Dr. Ziat holds an Electronic Engineering degree and a Master and Ph.D. in Cognitive Science.

Compared to a stationary pattern, a moving pattern dilates the perception of time. However, when it comes to comparing only moving stimulus, the exact dilation effects are less clear. The time dilation may be attributed to either speed of motion, temporal and spatial frequency, stimulus complexity, or the number of changes in the stimulus pattern....

Touch between people is an integral part of human life. Touch is used to convey information, emotions, and other social cues. Still, everyday remote communication remains mainly auditive or audio-visual. The theme of this article, interpersonal haptic communication, refers to any communication system that supports mediation of touch between two or...

In this study, we assessed the emotional dimensions (valence, arousal, and dominance) of the multimodal visual-cutaneous rabbit effect. Simultaneously to the tactile bursts on the forearm, visual silhouettes of saltatorial animals (rabbit, kangaroo, spider, grasshopper, frog, and flea) were projected on the left arm. Additionally, there were two lo...

The deployment of visual spatial attention can be significantly influenced in an exogenous, presumably bottom-up manner. Traditionally, spatial cueing paradigms have been utilized to come to such conclusions. Although these paradigms have primarily made use of visual cues, spatially correspondent tactile cues have also been successfully employed. H...

Contrary to order, randomness is the lack of predictability in events where there is no intelligible pattern to follow. In two current studies, we tested tactile randomness using local and global disturbances of a grid of 49 dots printed on PVC tiles. On the local scale, only one small portion of the grid was moved. On the global scale, every dot o...

When potters throw a vessel on a wheel, they use visual, proprioceptive/tactile, and auditory feedback. We asked 24 ceramics students to throw a vessel on a potter’s wheel when all possible pairs of these three sensory modalities were attenuated and, in the control condition, when none of the modalities was attenuated. The conditions were tested in...
