Final answer:
Behaviours associated with being confused or showing reduced alertness include difficulty with memory, understanding, focus, disorientation, and decision-making. Substances like alcohol or disrupted sleep patterns can lead to these behaviours.
Step-by-step explanation:
Behaviours associated with being confused or having reduced alertness can range from subtle to very noticeable. Some signs that a person is experiencing confusion or is less alert include difficulty remembering recent events or conversations, trouble understanding or following directions, and appearing distracted or unable to focus. Disorientation regarding time or place, and having a hard time making decisions or solving problems are also common behaviours. Substances like alcohol can exacerbate these issues, as even low doses of alcohol can lead to decreased reaction times, reduced behavioural control, and lowered levels of alertness. Sleep disturbances, such as jet lag or sleep disorders, can also contribute to these behaviours. Individuals with disrupted sleep may feel fatigued, irritable, and struggle with insomnia, all of which can impact their cognitive functions and make them appear confused or less alert.
