PROJECT SUMMARY/ABSTRACT The attentional focus in people who stutter (PWS) when speaking under social evaluative threat (SET) condi- tions and its effects on speech-motor control is unknown. My long-term goal is to advance treatment for PWS by supporting the need to integrate attention focus strategies in therapy in order to reduce anxiety and improve communication. The overall objectives in this application are to establish the effects of attentional shifts on speech motor control in PWS and determine how this relationship is influenced by social stress. The central hypothesis is that PWS engage a self-focus of attention when speaking under SET and this leads to a speech motor system that is more susceptible to breakdown. The rationale is that high anxious people who do not stut- ter shift to a self-focused attention when under SET and due to the high levels of anxiety reported in PWS, it is suspected that they also engage a self-focused attention when under SET. Due to their unstable articulatory coordination patterns, a self-focused attention is suspected to interfere with fluent speech. The hypothesis will be tested by pursuing three specific aims: 1) Determine the effects of cued attentional focus on articulatory control and stuttering frequency in adolescents and adults who stutter; 2) Determine the attentional focus in adolescents and adults who stutter when under SET and its effects on articulatory control and stuttering fre- quency; and 3) Determine the effects of cued attentional focus on articulatory control and stuttering frequency in adolescents and adults who stutter when speaking under SET. Under the first aim, adolescents and adults who do and do not stutter will repeat sentences under baseline, cued-internal, and cued-external attentional focus conditions. For the second aim, adolescents and adults who stutter will repeat sentences in front of an audience trained to exhibit negative, positive, or neutral behaviors. Attention will be assessed using the Detec- tion of Audience Behavior questionnaire and scores will be used to form subgroups based on attentional focus. For the third aim, adolescents and adults who stutter will repeat sentences under SET when engaging a cued- internal and – external attentional focus. Articulatory variability will be assessed using STI and RQA measures of lip aperture and posterior tongue. Number of stuttered sentences will be calculated. Age and self-reports of social anxiety will be used as covariates. Stressor effects will be assessed using skin conductance levels. The research proposed in this application is innovative because it will be the first to (i) assess whether PWS en- gage a self-focus of attention during SET, (ii) determine how changes in attentional focus affects speech motor control in PWS, (iii) include the much-needed assessment of tongue kinematics, and (iv) determine if cues to shift attention effects speech-motor control in AWS during SET conditions. The proposed project is significant because it will explain some of the inconsistencies in the literature reporting a destabilizing effect on speech- motor control in AWS when under social-cognitive demands by suggesting that attention plays a mediating role and support the development of therapeutic approaches that encourage healthy social interactions.

项目总结/摘要 社会评价威胁（SET）条件下口吃者（PWS）的注意聚焦特点 它对语言运动控制的影响是未知的。我的长期目标是推进PWS的治疗 通过支持在治疗中整合注意力集中策略的必要性，以减少焦虑并改善 通信本申请的总体目标是建立注意力转移对 PWS中的言语运动控制，并确定这种关系如何受到社会压力的影响。中央 假设是，PWS在SET下说话时参与自我注意焦点，这导致了演讲 运动系统更容易崩溃。其原理是，高度焦虑的人谁不口吃- 在SET下，由于PWS中报告的高水平焦虑， 怀疑他们在SET下也会引起自我关注。由于他们的发音不稳定 协调模式，自我集中的注意力被怀疑干扰流利的讲话。假设将 通过追求三个具体目标进行测试：1）确定线索注意焦点对发音的影响 控制和口吃的青少年和成人谁口吃的频率; 2）确定注意力集中在 青少年和成年人在SET下口吃，以及它对发音控制和口吃频率的影响。 频率; 3）确定线索注意焦点对发音控制和口吃频率的影响 在SET下说话时口吃的青少年和成年人。在第一个目标下，青少年和成年人 在基线、线索-内部和线索-外部注意下，口吃者和不口吃者会重复句子 聚焦条件。对于第二个目标，口吃的青少年和成年人会在一个人面前重复句子。 接受过展示消极、积极或中性行为的培训的观众。注意力将使用Detec- 观众行为问卷和分数将被用来形成基于注意力集中的亚组。 对于第三个目标，口吃的青少年和成年人在进行提示时会重复SET下的句子- 内外注意力集中。将使用STI和RQA指标评估发音变异性 唇孔和舌后部的位置。将计算口吃句子的数量。年龄和自我报告 社交焦虑将被用作协变量。将使用皮肤电导水平评估应激源效应。的 在这项申请中提出的研究是创新的，因为它将是第一个（i）评估PWS是否恩- 测量SET期间的自我注意力焦点，（ii）确定注意力焦点的变化如何影响言语运动 控制PWS，（iii）包括急需的舌头运动学评估，以及（iv）确定是否提示 转移注意力的影响语音电机控制在AWS在SET条件。拟议的项目意义重大 因为它将解释一些文献中报告的不一致之处，这些文献报告了对言语的不稳定影响- 当处于社会认知需求下时，AWS中的运动控制表明注意力起着中介作用 并支持鼓励健康社会互动的治疗方法的发展。
