Study Notes
Psychopharmacology and Sleep Disorders
- Alcohol is classified as a depressant, affecting mood and cognitive functions.
- Psychotropic substances, such as alcohol, marijuana, and cocaine, are known as psychoactive drugs due to their effects on perception and mood.
- Stimulants like nicotine increase alertness and can lead to addiction.
Hypnosis and Memory
- Individuals with high hypnotizability are more prone to developing false memories, raising concerns in therapeutic settings.
Sleep Patterns and Disorders
- Chronic sleep deprivation can lead to various negative effects including immune system suppression, hormonal imbalances, misperception during tasks, and increased accident risks.
- The sleep cycle lasts approximately 90 minutes, repeating multiple times during the night.
- Sleep apnea is characterized by interruptions in breathing during sleep, often accompanied by snoring.
- Night terrors typically occur during Stage 4 sleep, manifesting as intense fear or confusion while sleeping.
- REM (Rapid Eye Movement) sleep is linked to increased brain activity, including visual and auditory processing, and is the stage where dreams are often vivid.
Effects of Sleep Stages
- Stage 4 sleep is critical for physical growth and development.
- REM sleep is associated with genital arousal and increased heart rate, rare in other sleep stages.
- After repeated disturbances during REM sleep, individuals may experience a rebound effect, leading to increased REM sleep during the following undisturbed night.
Drug Effects and Risks
- Cocaine and crack create euphoria by blocking dopamine reuptake in the brain, stimulating pleasure centers.
- Alcohol contributes to the greatest number of drug-related deaths among substances.
- Users of euphoric drugs may develop tolerance, requiring higher dosages for the same effect, and will likely experience depression after each use.
Circadian Rhythm and Sleep Patterns
- Circadian rhythm disruptions, often experienced by shift workers, can lead to difficulties in initiating sleep during intended hours.
- In the sleep cycle, stage 4 sleep diminishes over the night while REM sleep increases in duration.
Observational Indicators
- Alpha waves, indicative of relaxation, can be detected via EEG when an individual is awake but calm.
- Characteristics of REM sleep include rapid eye movement and fluctuating heart rates, marking this stage distinctively from others.
Drug Use Trends
- Research indicates that black males report the lowest rates of drug use among high school seniors, providing insight into demographic differences in substance use.
- It is a misconception that adopted individuals are more susceptible to alcoholism if they had an alcoholic adoptive parent; rather, genetic factors play a significant role in addiction likelihood.
Memory and Eyewitness Testimony
- Attention to the accuracy of eyewitness testimonies is crucial in legal settings, and factors affecting memory recall must be critically assessed.
