Q
What are the 7 themes of psychology? (2)
A
- Psychology is empirical- based on evidence, not a pseudoscience
- Psychology is theoretically diverse- different perspectives my interpret behaviour differently

A procedure where a practitioner tries to alter changes in the sensations of a participant by proposing suggestions.
-Hypnosis is not sleep, and relies more on the person being hypnotized that the hypnotizer.
-Hypnosis does not do more than cause increased motivation, so nothing done during hypnosis is impossible to do outside of hypnosis.
-Hypnosis does not increase the accuracy of memory
116
What are the dissociation theories of hypnosis? (6)
That hypnosis is a split in consciousness where one part of the mind acts independently of another. Hypnosis causes a dissociation between an executive control system in the brain and other systems involved in thinking/acting

Large amounts cause anxiousness and jitteriness.
Extra large amounts can be fatal
137
What is caffeine? (6)
Caffeine is a stimulant that is commonly used to feel energized
138
Why is the consumption of both caffeine and alcohol dangerous? (6)
Consumption of both caffeine and alcohol is dangerous because the energized feeling of caffeine can hide the symptoms of the alcohol. This can cause the consumer to be unaware of how much alcohol they have consumed and can lead to overdoses
139
What is nicotine? (6)
Nicotine is a stimulant that activates the nicotine receptors in the brain, releasing feelings of pleasure and increasing metabolic function. It is highly addictive because of your body's specialized receptors and the quick ability to feel side effects
140
What is cocaine? (6)
Cocaine is a natural stimulant that comes from coca plant. It has a short symptom window (20-30 minutes), which results in more frequent usage to maintain the high. Cocaine increases dopamine levels by not allowing the body to recycle old dopamine, causing buildup
141
What are amphetamines? (6)
Amphetamines are manufactured stimulants that increase energy and lower appetite. Tolerance for amphetamines builds quickly, resulting in increased dosages and addiction
142
What is MDMA or ecstasy? (6)
Ecstasy is a "club drug" that causes feelings of euphoria, reduced anxiety, and increased social intimacy. Causes short term dehydration and difficulty concentration. Causes long term depression, anxiety, paranoia and irritability
143
What are hallucinogens? (6)
Hallucinogens alter consciousness by disrupting thought process. They cause changes in perception and experience. These changes experiences are commonly called "trips"
144
What is the pleasure pathway? (6)
The pleasure pathway is a reward pathway activatable by substances. It stretches from the ventral tegmental to the nucleus accumbens, leading to dopamine release. All drugs end up moving through the pleasure pathway regardless of where they are before that
145
What is LSD? (6)
LSD, or Lysergic Acid Diethylamide, is a hallucinogen.
146
What is cannabis? (6)
Cannabis is a natural hallucinogen, depressant and stimulant the comes from hemp plants. Moderate use affects your ability to transfer short term memories to long term memories.
147
What is introspection? (1)
Introspection is the examination of someone's own mental and emotional processes. Used in structuralism.
