Recent research indicates that individuals with autism do not effectively use inner speech during the completion of cognitive tasks. We used Articulatory Suppression (AS) to interfere with inner speech during completion of alternate items from the Tower of London (TOL). AS detrimentally affected TOL performance among typically developing (TD) adolescents (n = 25), but did not significantly diminish performance among adolescents with high functioning (IQ > 80) autism spectrum disorders (n = 28). Moreover, the TD group's TOL performance under AS was indistinguishable from the autism group's impaired baseline TOL performance. These findings suggest that diminished inner speech usage among individuals with high functioning autism spectrum disorders (relative to TD controls) may contribute to executive dysfunction associated with these disorders.
最近的研究表明,自闭症个体在完成认知任务时不能有效地使用内部言语。我们在完成伦敦塔任务(TOL)的交替项目时使用发音抑制(AS)来干扰内部言语。AS 对典型发育(TD)青少年(n = 25)的 TOL 表现有不利影响,但对高功能(智商 > 80)自闭症谱系障碍(n = 28)青少年的表现没有显著降低。此外,TD 组在 AS 下的 TOL 表现与自闭症组受损的基线 TOL 表现无法区分。这些发现表明,高功能自闭症谱系障碍个体(相对于 TD 对照组)内部言语使用减少可能导致与这些障碍相关的执行功能障碍。
