What symptom may indicate poor orthographic awareness in individuals?

The symptom that may indicate poor orthographic awareness in individuals is the tendency to transpose letters or numbers. Orthographic awareness refers to the understanding of the conventions of the writing system of a language, including the ability to recognize, remember, and manipulate the written forms of words. When an individual struggles with orthographic awareness, they may have difficulties distinguishing between similar letters or numbers, leading to transposition errors, such as writing 'b' instead of 'd' or mixing up the order of digits in a number.

In contrast, the other options represent skills or abilities that do not indicate a deficiency in orthographic awareness. For example, fast and accurate reading of irregular words implies a strong grasp of word recognition, which relates to good orthographic awareness. The ability to memorize math facts easily reflects cognitive capabilities unrelated to writing skills. Advanced writing skills indicate an individual's proficiency with written language, which likely includes strong orthographic awareness. Therefore, the tendency to transpose letters or numbers is a clear signal of challenges in understanding and applying the rules of orthography.
