Q

Activation-synthesis theory of dreams

A

(Hobson) posits that random neural firing activates mechanisms that normally interpret sensory input, and then the brain tries to make sense of this by synthesizing it with stored memories. Also, the limbic system –responsible for emotion and reward– is activated while dreaming, which is the source of the emotional content of dreams. Also posits that the deactivation of the prefrontal cortex is why the dreams are allowed to have their illogical structure.

Q

Hypnosis

A

A social interaction during which a person, responding to suggestions, experiences changes in memory, perception, and/or voluntary action. Psychologists disagree on whether hypnosis is really an altered state of conscience.

Q

Posthypnotic suggestions

Q

Sociocognitive theory of Hypnosis

A

Psychologists believe that people under hypnosis “play the role of the hypnotized person”. They are not faking being under hypnosis, but rather acts as if the hypnotist is the director and they are part of the cast of a metaphorical play. In other words, hypnotized people behave as they expect hypnotized people to behave. What’s more they

Q

neodissociation theory of Hypnosis

A

acknowledges the social context to hypnosis while also positing that hypnosis is an altered state of conscience. According to this theory, hypnosis is a trancelike state in which consciousness and awareness are separated (ie. disassociated) from other aspects of consciousness.

Q

Flow

A

A type of experience that is so engrossing and enjoyable that it is worth doing for its own sake even though it can have no consequence outside itself. A person experiencing flow might completely forget to eat, lose track of time, and the person’s skills are well matched with the problem at hand. People can participate in flow activites both to escape their worries, but they mainly participate in order to achieve personal fulfillment.

Q

How do dopamine receptors play into drug abuse?

A

Activation of dopamine receptors seems to be related to drug abuse in two ways: First, the activation of dopamine receptors is linked with greater reward, or increased liking. Second, the increase in dopamine leads to a greater desire to take a drug, even if the drug does not produce pleasure. Dopamine neurotransmitter systems are mainly involved in stimulants’ effects (not other types, excluding the mixed category of course)

17
Q

How does cocaine get someone high?

A

Increases the concentration of dopamine in synapses.

18
Q

Effects of habitual cocaine use

A

Paranoia, psychotic behavior, and violence.

19
Q

How do amphetamines get someone high?

A

Same as cocaine; they increase the concentration of dopamine in synapses.

20
Q

Side effects of amphetamines

A

insomnia, anxiety, and potential addiction

21
Q

How does meth get someone high?

A

It blocks reuptake of dopamine while also increasing its release. It also stays in the body much longer than cocaine and so its effects are prolonged.

22
Q

How do opiods get someone high

A

They increase pleasure by binding with opiate receptors, while also increasing wanting of the drug by indirectly activating dopamine receptors.

23
Q

How does alcohol produce its effects

A

Activating GABA receptors, and GABA is the main inhibitor of the nervous system.

24
Q

Tolerance

A

A physical dependence on a drug to the extent that a person needs more of the drug in order to get high. Failing to ingest a drug leads to symptoms of withdrawal. A person can be psychologically dependent on a drug without showing symptoms of tolerance or withdrawal.

25
Q

Components of the brain important for addiction to drugs

A

The nucleus accumbens is very important because dopamine activity in it underlies the “wanting” properties of taking drugs. The prefrontal cortex, amygdala, thalamus, and hippocampus are also important in this regard. Another brain region that is very important is the Insula, which seems to be responsible for the craving component of addiction.

26
Q

Traits of vulnerability to addiction

A

High trait of sensation seeking (a personality trait that involves attraction to novelty and risk taking), as well as genetic components –especially for alcoholism (though there does not exist a single gene associated with addiction). These genetic traits include personality traits such as: risk taking, impulsivity, a reduced concern about personal harm, a nervous system chronically low in arousal, or a predisposition of finding chemical substances pleasurable.
