At what age is stuttering most likely to remit spontaneously according to the data provided?

The most likely age for stuttering to remit spontaneously, according to research, is around age 5. This is a critical period in language development for children, and many who experience stuttering in early childhood will naturally outgrow it as their speech and language skills develop. The majority of children who stutter will show significant improvement by this age, making it an essential marker for spontaneous remission.

While some children may continue to stutter past age 5, the chances diminish significantly after this age. The prevalence of stuttering tends to decrease as children mature and gain more experience with language and communication. Therefore, pinpointing age 5 as the most likely time for spontaneous remission aligns well with the developmental trajectory of most children who stutter.

In contrast, ages 10, 12, and 16 represent timeframes where stuttering is less likely to remit spontaneously, as many cases become more chronic and may require intervention. Thus, age 5 is recognized as the optimal age for spontaneous recovery from stuttering, which supports why this answer is deemed correct.
