Explicit and implicit cognitive processes of the public towards people who stutter.

PURPOSE: The Public Opinion Survey of Human Attributes - Stuttering (POSHA-S, St. Louis, 2013) was developed as a standard measure of public attitudes about people who stutter. As with any survey-based methods, threats to validity may occur because of social desirability bias. Using computer mouse-tracking, we were interested in observing changes in cognition that are manifested in intentionality through action by evaluating underlying cognitive processes that drive social judgments of people who stutter. METHODS: Twenty-two women, 1 non-binary person, and 47 men reported using a computer mouse to complete an online, remote, and modified version of the POSHA-S. Responses were categorized as correct/helpful or incorrect/unhelpful relative to each component of the POSHA-S and were used as measures of explicit cognitive processes. Computer-mouse trajectory metrics, including area under the curve (AUC) and reaction time (RT), were used to measure implicit cognitive processes. RESULTS: Although participants' explicit responses were significantly more likely to be correct/helpful than incorrect/unhelpful, with endorsement of correct/helpful prompts 77 % of the time, participants also endorsed incorrect/unhelpful prompts more than half (i.e., 52 %) of the time. Familiarity with people who stutter was associated with disagreeing with incorrect/unhelpful prompts. As indicated by greater AUC, participants exhibited significantly more implicit cognitive processes indicating competition when responding "disagree" compared to "agree", regardless of whether the prompts were correct/helpful or incorrect/unhelpful. Similarly, participants took significantly longer to respond to prompts with "disagree" rather than "agree". CONCLUSION: The findings of this study offer evidence of participants reporting cognitive processes that are overall more correct/helpful than incorrect/unhelpful, in their explicit responses to the dichotomous response tasks of the POSHA-S. However, these findings are tempered by evidence of a tendency to agree with statements in the measure and suggest the need for further research to increase understanding of how to measure and improve explicit and implicit cognitive processes related to people who stutter.

Electrodermal Activity of Preschool-Age Children Who Stutter During a Child-Friendly Stroop Paradigm.

PURPOSE: The aim of the study was to assess whether emotional reactivity, indexed by a distinct physiological measure of sympathetic activation, differs between preschool-age children who stutter (CWS) and preschool-age children who do not stutter (CWNS) during a child-friendly Stroop task (i.e., day-night task). Additionally, researchers aimed to assess whether the Stroop task, compared to a control task, was a significant physiological stressor. METHOD: Fifteen preschool-age CWS and 22 preschool-age CWNS were asked to perform a day-night Stroop task in order to elicit psychophysiological reactivity, indexed by electrodermal response (EDR) occurrence frequency and EDR amplitude. Physiological measurements were recorded during pretask baselines, performance of the day-night Stroop task, and performance of a speech-language control task. RESULTS: Findings based on EDR measures did not support the hypothesis that the child-friendly day-night Stroop task is an effective stressor as compared to a control task based on measures of physiological arousal in preschool-age children. The CWS and CWNS did not significantly differ in their EDR measures relative to the control task or Stroop task (p > .05). However, CWS, compared to CWNS, exhibited significantly greater EDR amplitudes during the control task baseline (p < .05) and the Stroop task baseline (p < .05). CONCLUSION: Overall, these findings may suggest that a predisposition to heightened levels of sympathetic activity prior to tasks in preschool-age CWS is important to consider with regard to the nature of developmental stuttering.

Perspectives of stuttering treatment: Children, adolescents, and parents.

PURPOSE: Researchers investigated whether children who stutter (CWS), adolescents who stutter (ADWS), and their parents preferred treatment focused on changing speech or communicating regardless of stuttering. METHODS: Twenty-four parents and their CWS (n = 11, ages 8;0-12;11) or ADWS (n = 13, ages 13;0-17;11) answered questions about their preferences for stuttering treatment via an internet-based survey; an additional 11 surveys were filled in only by parents without responses by their child/adolescent. The researchers compared responses of the parents and their children, as well as between the two age groups and years in treatment (less than five years versus five or more years). RESULTS: Views tended to be mixed without any clear trends based on age. Just over half of the CWS, ADWS, and parents of CWS indicated a general tendency for therapy satisfaction; however, less years of treatment were associated with more satisfaction. When presented with a specific scenario, a higher proportion of parents expressed focus on their child saying what they want to say, regardless of stuttering. Otherwise, preferences were mixed on therapy goals of speaking freely vs. speaking more fluently. CONCLUSIONS: Preferences for treatment goals do not predictably vary based on age or years in treatment; given the small sample size, these findings should be considered with caution. Given the variability in responses, it is evident that stuttering treatment for school-age children and adolescents should be individualized. These results also emphasize the importance of communication, education, and applying a person-centered approach when providing stuttering intervention to children, adolescents, and their parents.
