The present investigation is a follow-up to a longitudinal speech and academic study involving approximately 400 normally developing children begun in 1960 by Mildred Templin. From this large data base, the present project invited the participation of two groups of subjects (now aged 32 to 34): (a) 24 adults with a documented history of moderately severe phonological disorder that persisted at least through the end of first grade (probands) and (b) 28 adults from the same birth cohort and schools who were known to have had at least average articulation skills over the same period (controls). Results of follow-up testing revealed that the proband adults performed significantly more poorly than the control adults on all of the administered measures of articulation, expressive language, and receptive language. Results obtained from a screening of nonverbal reasoning ability were equivocal. On a questionnaire measure of personality, both groups scored well within the normal range for the dimensions of extroversion and neuroticism when compared to the test's normative sample. These results have been interpreted as suggesting that although many adults with a childhood history of delayed phonological development will continue to experience linguistic outcomes that are less favorable than those of controls, their performance in selected nonlanguage domains (e.g., nonverbal reasoning, personality) will be far more typical of the general population.
本研究是一项跟踪研究,其对象是米尔德丽德·坦普林于1960年开始的一项针对约400名发育正常儿童的纵向言语与学业研究中的参与者。基于这个庞大的数据库,本项目邀请了两组受试者(现年龄为32至34岁)参与:(a) 24名成年人,他们有中度严重语音障碍的记录,至少持续到一年级结束(先证者);(b) 28名来自同一出生队列和学校的成年人,已知他们在同一时期至少具备平均水平的发音技能(对照组)。随访测试结果显示,在先证者组的成年人在所有发音、表达性语言和接受性语言的测试指标上的表现都明显低于对照组的成年人。非言语推理能力筛查的结果不明确。在一项人格问卷调查中,与测试的常模样本相比,两组在外向性和神经质维度上的得分都处于正常范围内。这些结果被解释为表明,虽然许多有童年语音发育延迟病史的成年人在语言方面的表现仍将继续不如对照组,但他们在某些非语言领域(如非言语推理、人格)的表现将更符合一般人群的特征。
