I need to reply to this classmate's response:
Psychology defines consciousness as a person's awareness of their mental and physical experiences, including their feelings, thoughts, and perceptions. It is frequently compared to an ever-evolving, fluid stream. Disturbances in cognitive functions or emotional regulation are signs of disorders of consciousness, which depart from normal functioning. For example, disorders such as schizophrenia or extreme drug abuse can result in disordered states that affect a person's capacity to understand reality in a cohesive manner. Conversely, altered states of consciousness entail a departure from the typical waking state and are frequently brought about by outside influences like hypnosis, meditation, or drugs that cause hallucinations. These altered states, in contrast to the typical cognitive and perceptual framework, can offer novel insights or experiences. Comprehending these contrasts is essential to understanding the various ways that human consciousness manifests itself.
