The present experiment was a preliminary attempt to use the psychophysical scaling methods of magnitude estimation and cross-modal matching to investigate suprathreshold judgments of lingual vibrotactile and auditory sensation magnitudes for 20 normal young adult subjects. A 250-Hz lingual vibrotactile stimulus and a 1000-Hz binaural auditory stimulus were employed. To obtain judgments for nonoral vibrotactile sensory magnitudes, the thenar eminence of the hand was also employed as a test site for 5 additional subjects. Eight stimulus intensities were presented during all experimental tasks. The results showed that the slopes of the log-log vibrotactile magnitude estimation functions decreased at higher stimulus intensity levels for both test sites. Auditory magnitude estimation functions were relatively constant throughout the stimulus range. Cross-modal matching functions for the two stimuli generally agreed with functions predicted from the magnitude estimation data, except when subjects adjusted vibration on the tongue to match auditory stimulus intensities. The results suggested that the methods of magnitude estimation and cross-modal matching may be useful for studying sensory processing in the speech production system. However, systematic investigation of response biases associated with vibrotactile-auditory psychophysical scaling tasks appears to be a prerequisite.

On November 5, 2016, hundreds of people convened at the historical landmark of Chicano Park in Barrio Logan, San Diego, to celebrate the life of one of the community’s most revered elders, Ramón “Chunky” Moroyoqui Sánchez. Nuestro querido maestro falleció el día 28 de octubre de 2016. Sánchez, endearingly known as Chunky, was synonymous with Barrio Logan, Chicano Park, Chicano/a music, and San Diego in general. In this city, an auditorium is named in his honor. His image is incorporated in murals. The Chicano comedy troupe Culture Clash developed a vignette about Chunky, and upon his passing the San Diego Chargers’ website featured him in a blog post that included a photo of him with players and cheerleaders. Chunky was also well known beyond the Imperial Valley. The music of Los Alacranes Mojados (the group he started with his brother, Ricardo Sánchez) continues to be embraced in Mexicano/a and Chicano/a communities throughout California and the Southwest. The news of Sánchez’s passing reverberated throughout California like the violent ripples of a pond into which a boulder has been dropped. Ese vato will be missed.
