Effects of CaSe AlTeRnAtIoN were studied in two lateralized visual lexical decision experiments. We manipulated word length and letter case (UPPER, lower and MiXeD) in both English (Exp. 1, N=60) and Hebrew (Exp. 2, N=60). The previously reported visual field and word length interaction was found for upper and lower case presentation, but not for MiXeD CaSe, where both fields were affected by w...

In this paper, we discuss some properties of relations between a mixed graph and its line graph, which are used to characterize the Laplacian spectrum of a mixed graph. Then we present two sharp upper bounds for the Laplacian spectral radius of a mixed graph in terms of the degrees and the average 2-degrees of vertices and we also determine some extreme graphs which attain these upper bounds. ©...

Visual and aural modes are two main manners that human utilize to senses the world. Their relationship is investigated in this work. EEG experiments involving mixed aural and visual modes are designed, utilizing HilbertHuang Transform (HHT) and electroencephalogram (EEG) signal processing techniques. During EEG data processing, I-EEMD method of similar weighted average waveform extension is pro...

This study explored whether and how teachers’ mathematical knowledge for teaching contributes to gains in students’ mathematics achievement. The authors used a linear mixed-model methodology in which first and third graders’ mathematical achievement gains over a year were nested within teachers, who in turn were nested within schools. They found that teachers’ mathematical knowledge was signifi...

The effects of talker variability on visual speech perception were tested by having subjects speechread sentences from either single-talker or mixed-talker sentence lists. Results revealed that changes in talker from trial to trial decreased speechreading performance. To help determine whether this decrement was due to talker change--and not a change in superficial characteristics of the stimul...
