Flashcards in Biological Explanations for Gambling - Addiction Deck (7):
1

How can neurotransmitters explain initiation?

- Gamblers have lower levels of noradrenaline
- Due to having such low levels gamblers take up gambling to make up for this
- Studies have found that noradrenaline + adrenaline levels increase when gamblers play

2

How does Meyera's study help to explain imitation?

Studied 14 male problem gamblers and 15 non problem gamblers:
- When playing blackjack noradrenaline levels increased in both groups but problem gamblers showed significantly higher levels
= shows they may have low levels which is why they increase more as only get this feeling from gambling

3

How can neurotransmitters explain maintenance?

- Gambling causes you to feel extremely high due to high levels of dopamine
= creates an insensitivity to dopamine which makes you feel low
- Addicts keep up gambling to feel 'normal'
- For gamblers exposure to gambling related audio and visual stimuli can create arousal causing them to seek more optimum levels of dopamine

4

How does Meyera's study help to explain maintenance?

Dopamine levels were significantly higher in problem gamblers when playing
= get more of a reward than no problem gamblers + perhaps no other activity can successfully raise dopamine as they have become insensitive

5

How can neurotransmitters explain relapse?

- Gamblers often miss the psychological/physiological rewards of stress reduction and excitement causing them to seek this when they feel low

6

How can Meyera's study help to explain relapse?

The high levels of both noradrenaline and dopamine shows how problem gamblers may miss them

7

What did other evidence show about the neurotransmitter levels of different types of gamblers?

Horserace addicts had significantly lower baseline levels as compared to poker machine platers and controls
= smaller bet size on poker machines causes less of a response
