PSY1010_W3_States_of_Consciousness.html

Sensory PerceptionPsychology has returned to the study of consciousness. How we pay attention to our environment and those who inhabit it has an effect on our perceptions. We can be selective in our attention, for example when we want to listen to a specific person's voice in a crowded room. We can also be oblivious to our surroundings, for example when we are daydreaming.

How does sleep fit into this? Sleep, it is postulated, is related to our ecological niche, allowing us to regenerate physically and mentally. There are indications that sleep may also have a role in our growth process.

Hypnosis, it has been suggested, is an altered state of mind. It might, however, be more of a divided consciousness. There are many misconceptions about what it is and what it can allow a person to do. Your text will cover it in more detail.

Certain drugs are used to change a person's perception of their surroundings and of themselves. Psychological reasons can be cited as contributing to a person's decision to abuse drugs. Self-esteem, peer-pressure, and certain social influences can singly, or in combination, make a person disposed to experiment with psychoactive drugs regularly.

Conclusion

Our discussion this week included the brain's use of sensations like vision, hearing, touch, taste, smell, and kinesthetics. The way the brain perceives the world is also an area of interest to psychology. The levels of consciousness were also mentioned.
