Likewise, you can’t perceive how others do (we’re all a mystery to each other). B) It’s ever-changing- Everyday we transfer in and out of many different states of consciousness. C) We’re aware of it- No matter what state we are in we are aware of our conscious thoughts. D) Connected to selective attention. 2. Psychologists measure consciousness in the following ways: SUBJECTIVE MEASURES Self-report- this method gives psychologists detailed insights into subjective experiences, but can be flawed because there is no way of verifying the information given. OBJECTIVE MEASURES Physiological measures- using EEG scans to measure brain activity in different states of consciousness allows psychologists to characterize them. Behavioural measures- this method uses experiments such as the rouge test to determine whether certain things are consciously recognized by the subjects. 3. Freud’s explanation of consciousness consisted of three levels: A) Conscious  Stuff we are currently aware of B) Preconscious  Stuff we are not currently aware of, but can be easily recalled if triggered by stimulus. C) Unconscious  Things we are not conscious/aware of 4. The cognitive perspective believes that the unconscious and conscious states are compliments. Put simply, they work as a team and guide us together through many daily functions. 5. Automatic processing occurs when activities require little to no conscious effort. Common among thoroughly practiced movements. It is important because it helps us to do many things without having to consciously think about them and takes the mental factor our of things. 6. Yes, it has been proven that unconscious stimulus can greatly influence mood. 7. The modular model of the mind describes the mind as a bunch of deeply interconnected networks of information that take information from each other to create their own information. So, using this point of view, consciousness arises through all of these smaller modules working together to form a state of consciousness. 8. The brain’s SCN regulates circadian rhythm’s by causing the pineal gland to secrete melatonin, a hormone that has a relaxing effect on the human body. However, the environment also plays a very important role. Our eyes have sensory connections to the SCN and it’s a lack of daylight that causes the SCN to stimulate the pineal gland. 9. If someone wasn’t exposed to a regular night-day cycle they would fall into a free running circadian rhythm. A free running rhythm is characterized by a lack of stimuli to control the secretions of melatonin. For example, if someone was living in a pitch black cave or in permanent daylight they would most likely suffer from free running circadian rhythms. 10. SAD- daylight becomes less and less as the winter months are ushered in. This greatly effects some people’s circadian rhythms because the amount of daylight received is much less, thereby stimulating more regular release of melatonin. Jetlag- flying over many time zones can have a negative effect on us because it is directly throwing off our circadian rhythms by either lengthening/shortening our days. Nigh shift-work- completely switching around our circadian rhythms can be very difficult. Often on days off night workers go back to regular rhythms and completely throw themselves off again and again. 11. Phototherapy is used to treat SAD, it consists of exposure to artificial daylight to increase wakefulness and decrease depression. 12. Awake (and REM)- Beta Waves Stage 1- Theta waves Stage 2- Appearance of sleep spindles Stage 3- Appearance of delta waves Stage 4- All delta waves 13. - Rapid eye movement - Genital arousal - REM paralysis - Vivid dreaming - Beta waves 14. Areas at the base of the forebrain help to induce sleep, while the reticular formation/pons is responsible for initiating REM sleep. 15. Three changes: A) We sleep less- an infant sleeps 16 hours whereas a teen sleeps an average of 8 hours per night. B) Less REM- amount of time spent in REM decreases substantially over infancy and early childhood but remains steady thereafter. C) Sleep lighter- as we grow older, th
More Less
