Final answer:
Difficulty with planning and executing tasks and trouble learning new motor tasks are possible symptoms of impaired planning and sequencing of movement, which can also result in balance and posture problems as well as repetitive motor behaviors.
Step-by-step explanation:
A possible symptom of impaired planning and sequencing of movement could be difficulty with planning and executing tasks. This often encompasses challenges in organizing the steps to a task, initiating the steps, and executing them in the correct sequence. Another possible symptom is having trouble learning new motor tasks, as these can require the ability to plan and coordinate different movements.
Impaired planning and sequencing of movement can also lead to balance and posture problems, that manifest as difficulties in maintaining a steady and stable body position. Moreover, someone with such impairments might exhibit repetitive motor behaviors, which can be seen as doing the same movement over and over again without a clear purpose or ability to stop.
