“…However, it is possible that an educational emphasis on the growing body of basic research on the nature of stuttering has led clinicians to apply an educationally enculturated form of clinical bias in dealing with accumulated evidence of neurophysiological, physiological, neurolinguistic and cognitive factors in the disorder. Because so much research into developmental disorders now emphasizes "constitutional" factors in their etiology, I do not find it surprising that surveys show a recent slight downturn in interest in the use of purely operant programs (Crichton- Smith, Wright, & Stackhouse, 2003;Kuhr, 1994) by clinicians. The "traditional" approaches tend to emphasize components that include fluency shaping, stuttering modification, densensitization and establishment of self-efficacy and locus of control (LOC), each of which has therapy goals grounded in part in neurophysiological research.…”
