Times New Roman and Arial typefaces in 10and 12-point, dot-matrix and anti-aliased format conditions were compared for readability (accuracy, reading speed, and accuracy/ reading speed), as well as perceptions of typeface legibility, sharpness, ease of reading, and general preference. In assessing readability, the 10-point anti-aliased Arial typeface was(More)
This study examined passages containing two serif and sans serif fonts at 12 and 14-point sizes for differences in legibility, reading time, and general preference when read by an older population. A significant main effect of size was found for font legibility in that 14-point fonts were more legible to read than 12-point fonts. A marginal interaction was(More)
This study examined where individuals expect specific web-related objects to be located on a typical web page. The web objects examined were: web page title, internal and external grouping of links, a link to the homepage, internal search engine, and advertisement banner(s). The results suggest that users do have definable expectations concerning the(More)
OBJECTIVE This study investigated the association between mindfulness, other resilience resources, and several measures of health in 124 urban firefighters. METHOD Participants completed health measures of posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, physical symptoms, and alcohol problems and measures of resilience resources(More)
BACKGROUND The electrocardiographic T-wave peak to T-wave end interval (Tpe) correlates with dispersion of ventricular repolarization (DVR). Increased DVR increases propensity toward electrical reentry that can cause ventricular tachyarrhythmia. The baseline rate-corrected Tpe (Tpec) has been shown to predict ventricular tachyarrhythmia and death in(More)
A model-free, biologically-motivated learning and control algorithm called S-learning is described as implemented in an Surveyor SRV-1 mobile robot. S-learning demonstrated learning of robotic and environmental structure sufficient to allow it to achieve its goals (finding highor low-contrast views in its environment). No modeling information about the task(More)
BACKGROUND The purpose of this study was to develop a model to predict the emotional and behavioral responses to an avian flu outbreak. METHODS The participants were 289 university students ranging in age, income, and ethnic backgrounds. They were presented with scenarios describing avian flu outbreaks affecting their community. They reported their(More)
This study investigated how common online text aVects reading performance of elementary school-age children by examining the actual and perceived readability of four computer-displayed typefaces at 12and 14-point sizes. Twenty-seven children, ages 9 to 11, were asked to read eight children’s passages and identify erroneous/substituted words while reading.(More)
This study examined the perceived font legibility, ease of reading, and font sharpness, as well as perceptions of font attractiveness, fun/personality, and general preference of two serif (Times New Roman and Georgia) and sans serif (Arial and Verdana) fonts at 12and 14-point sizes on a computer by older adults (mean age of 70). The results revealed that(More)
Encoding sensor observations across time is a critical component in the ability to model cognitive processes. All biological cognitive systems receive sensory stimuli as continuous streams of observed data over time. Therefore, the perceptual grounding of all biological cognitive processing is in temporal semantic encodings, where the particular grounding(More)
