The picture exchange communication system (PECS) is an augmentative communication system frequently used with children with autism (Bondy & Frost, 1994; Siegel, 2000; Yamall, 2000). Despite its common clinical use, no well-controlled empirical investigations have been conducted to test the effectiveness of PECS. Using a multiple baseline design, the present(More)
This study examined the effects of selective attention versus stimulus competition on the late auditory evoked potential (LAEP) in 20 young and 20 elderly listeners. In a series of test runs, different oddball tonal sequences were presented to one or both ears, and listeners were instructed to attend to tones at a specific target ear. Peak amplitudes were(More)
Turning is one of the most important maneuvers for biological and robotic fish. In our group's prior work, an analytical framework was proposed for modeling the steady turning of fish, given asymmetric, periodic body/tail movement or deformation. However, the approach was not illustrated with simulation or validated with experiments. The contributions of(More)
As interest in video games increases, so does the need for intelligent access to them. However, traditional organizational systems and standards fall short. To fill this gap, we are collaborating with the Seattle Interactive Media Museum to develop a formal metadata schema for video games. In the paper, we describe how the schema was established from a(More)
Effects of active versus passive listening on the N1 and P2 components of the late auditory evoked potential were examined in 20 young adults following instructions to ignore and later to attend to different trains of frequent and deviant tones presented to one or both ears. To distinguish monaural from binaural neural refractory or recovery effects,(More)
