Workaholism, sleep disorders, and potential e-learning impacts among Menoufia university staff during COVID-19 pandemic.

Background: Workaholism is described as a constant, internal drive to work and behavioral addiction to work. Studies have shown the negative associations between workaholism, job performance, and health results as disrupted sleep. The purpose of this research was to compare the prevalence of workaholics among the academic staff of practical and theoretical Faculties in Egyptian universities using the Dutch Workaholism Scale (DUWAS) and to determine associated sleep problems.

Express saccades in distinct populations: east, west, and in-between.

Express saccades are low latency (80-130 ms), visually guided saccades. While their occurrence is encouraged by the use of gap tasks (the fixation target is extinguished 200 ms prior to the saccade target appearing) and suppressed by the use of overlap tasks (the fixation target remains present when the saccade target appears), there are some healthy, adult participants, "express saccade makers" (ESMs), who persist in generating high proportions (> 30%) of express saccades in overlap conditions. These participants are encountered much more frequently in Chinese participant groups than amongst the Caucasian participants tested to date.

A Complex Story: Universal Preference vs. Individual Differences Shaping Aesthetic Response to Fractals Patterns.

Fractal patterns offer one way to represent the rough complexity of the natural world. Whilst they dominate many of our visual experiences in nature, little large-scale perceptual research has been done to explore how we respond aesthetically to these patterns. Previous research (Taylor et al.

The role of convexity in perception of symmetry and in visual short-term memory.

Visual perception of shape is affected by coding of local convexities and concavities. For instance, a recent study reported that deviations from symmetry carried by convexities were easier to detect than deviations carried by concavities. We removed some confounds and extended this work from a detection of reflection of a contour (i.

The shape of a hole and that of the surface-with-hole cannot be analyzed separately.

Figure-ground organization has a central role in visual perception, since it creates the regions to which properties, such as shape descriptions, are then assigned. However, there is disagreement on how much shape analysis is independent of figure-ground. The reversal of figure-ground of a single closed region is the purest form of figure-ground organization, and the two resulting percepts are that of an object and that of a hole.
