Week 1 Flashcards
What are the two kinds of addiction?
1) substance addiction and 2) behavioral addiction
What are the 5 intensional definitions mentioned in Sussman?
1) physiological and psychological dependence
2) impulsive-obsessive/compulsive behavior
3) self-medication
4) self-regulation
5) addiction entrenchment
Self-regulation is a way to define addiction. Which 3 theories are suggested concerning self-regulation?
1) BAS-BIS system
2) incentive-sensitization theory
3) allostasis
What is the incentive-sensitization theory?
It considers addiction as a balance between ‘liking’ and ‘wanting’.
What are the 3 extensional definitions mentioned in Sussman?
1) six-component definition
2) five-component definition
3) DSM-V
What is the six-component definition?
It considers six components to addiction, namely salience, mood modification, tolerance, withdrawal symptoms, conflict and relapse
What is the five-component definition?
The five components of this definition on addiction are: appetitive effects, satiation, preoccupation, loss of control, negative consequences.
What three reasons are named by Lopez Leon and Raley on the greater risk of adolescence for addiction?
Experimenting, brain development and attitudes
What is the gateway hypothesis?
This hypothesis states that experimentation with cannabis leads to usage of illegal substances. Supporting explanations of this hypothesis are at biochemical level, individual learning level, societal level, and cognitive impairment level. Other variables also affect the course of use, including substance availability, birth cohort, comorbid psychiatric illnesses/dual diagnoses, and non-diagnostic personal characteristics.
What is the reverse gateway hypothesis?
This hypothesis claims that for some cannabis use precedes nicotine use. Explanations include reducing the sedative effect and enhancing the rewarding effects and reinforcing effects of cannabis.
(…) and (…) are associated with later alcohol problems according to Gladwin et al.
Age of initiation, heavy drinking
What is the COM-B model?
This model suggest that Capability, Motivation and Opportunity all predict Behavior.
What three neurological developments during adolescence are discussed in the first lecture?
- Strong grow in brain volume: increase in white matter (connections), decrease in grey matter (nerve cells)
- Increase in white matter: communication between brain regions strongly improves (Long term memory increases, capacity for abstract thinking/ metacognition increases)
- High plasticity of the brain
What is the maturational imbalance model?
Increased risk-taking during adolescence is a result of an imbalance between motivational bottom-up versus
controlling top-down processes (high reward sensitivity versus immature impulse control). The affective-motivational system (emotional brain) develops fast, while the control system (rational brain) develops slowly.
Which substance has the highest risk for addiction?
Nicotine is the highest because it is easier to sustain, not that expensive and easily available.
What are three types of drugs? Give examples of each.
Hallucinogens (LSD, magic mushrooms), downers (heroin, alcohol), and uppers (cocaine, nicotine).
The DSM-V contains criteria for substance use disorder. Which four categories in criteria can be found?
Loss of control, social and other impairments, continuation despite knowledge of risky use, pharmacological effects.
What are two learning principles underlying the development of addiction?
Positive reinforcement occurs when the rate of a behavior increases because a desirable event (e.g., euphoria, relaxation) is resulting from the behavior. Negative reinforcement occurs when the rate of a behavior increases because an aversive event is prevented from happening (e.g., prevention of withdrawal symptoms).
How do we define risk behavior?
Behaviors that pose a risk to a healthy physical, cognitive, psychosocial development of adolescents.
How do we define psychoactive substances?
Psychoactive substances are chemical substances that cross the blood-brain barrier and affect the function of the central nervous system thereby altering perception, mood, or consciousness (causing craving and loss of control).
