Which of the following is a symptom of poor memory span in individuals?

The symptom of poor memory span in individuals is characterized by challenges in processing and retaining information over a short period. Difficulty counting in a sequence is a clear indicator of a reduced ability to hold and manipulate information in working memory. When someone struggles with tasks that require the recall of numbers or letters in order, it suggests that their capacity to remember and use sequential information is compromised.

In contrast, outstanding memorization of complex concepts, fluency in reading, and rapid recognition of symbols indicate strong memory capabilities rather than deficits. These skills require an efficient memory system to encode, store, and retrieve information successfully. Thus, the focus on counting in a sequence specifically aligns with a symptom suggesting issues with memory span, reflecting a limitation in this cognitive area.
