Study Notes
REM Sleep
- Often referred to as paradoxical sleep due to increased brain activity compared to wakefulness.
Adolescent Risk Factors
- High school seniors like Deano, who are attracted to novelty and have poor parental relationships, are at risk for substance experimentation, including alcohol and illegal drugs.
Subliminal Processing
- Tawny's craving for Dr Pepper, triggered by her roommate's reminder of previous exposure, exemplifies subliminal processing.
Minimally Conscious State
- Garland's ability to elicit brain activity resembling that of healthy individuals through mental imagery, despite appearing unconscious, indicates he is in a minimally conscious state.
Impact of Crack Cocaine
- Users like Chuck experience a shift from sociability and energy to paranoia and violent tendencies with prolonged use of crack cocaine.
Split-Brain Functionality
- G.C., a split-brain patient, can process and respond to visual stimuli in his right visual field, enabling him to warn a woman of a hazard he perceives.
Methamphetamine Effects
- This popular drug alters consciousness by blocking dopamine reuptake and increasing release, leading to long-term neurological and physical damage.
Dream Characteristics
- Tom's vividly emotional and disjointed dream content can be attributed to multiple factors being correct regarding dream perception.
Hypnosis and Visualization
- The diminished activity in the visual cortex for hypnotized participants demonstrates support for the dissociation theory of hypnosis, indicating altered states of perception.
Attention and Driving
- Texting while driving is hazardous due to a limited capacity for conscious attention, which hampers quick responses to unexpected events on the road.
Importance of Sleep
- According to the consolidated theory, activities like an all-nighter for studying are counterproductive, as they undermine essential functions of sleep.
