Unlike other psychophysiological measures of reward processing that involve cumbersome electrodes and wires (which may reduce ecological validity, and may inhibit flow), our new measures of dark and light flow were derived from the simple act of playing commercially available slot machines as people normally play them. Moreover, these measures do not depend on arousal, valence, or reward-related neural activity, and therefore have high ecological validity.
In contrast to previous research that has focused mainly on the cognitive and behavioral components of gambling, our studies have incorporated multiple dimensions of the experience of slot machine play and have compared it with other forms of casino gambling. Our findings indicate that the allure of slots is due to a combination of factors that vary across individuals, including their individual preferences for sensory and affective stimuli, and the degree to which these preferences are met.
During the first iteration of the slot machine, Sittman and Pitt developed a drum-based system that used five drums holding 50 card faces each. The player depressed a spin button, which activated the machine’s mechanical reels and landed them randomly on the cards. The player then received a payout depending on which symbols matched up with the winning payline. Today’s modern slot machines use random number generators to determine the positions of symbols on a reel, with an algorithm that cycles thousands of numbers each second.
