“…This low percentage is discouraging because the experiment represents the most straightforward and potent way to determine cause-and-effect relationships. On the other hand, at least some experimental work is being done in the area (e.g., Brandt & Pietras, 2008;Dixon & Schreiber, 2004).…”

The Effect of Male Confederate Presence, Betting, and Accuracy of Play on Males’ Gambling on Blackjack

Previous research suggests that the actions of a confederate can alter participants' gambling behavior. In the present experiment, male participants played Blackjack either alone or in the presence of a confederate. The confederate either quit early in the session or played for the entire session. Across sessions in which the confederate played for the entire session, how much the confederate bet per hand and how accurately he played were manipulated. Participants gambled significantly more money across the session when a confederate played the entire session than when a confederate left early in the session. During sessions in which the confederate played for the entire session, the number of hands participants played and their total amount bet varied directly with the confederate's bet size. Overall, the results indicate that gambling behavior can be indirectly influenced by another's gambling behavior, which may provide useful data for researchers and therapists seeking to predict and control gambling behavior.

“…This finding suggests a possible interaction between the effect of near wins and RTP on percentage of observing for the S+. These results are inconsistent with the literature that has shown that different RTP percentages have no effect on betting behaviour (Brandt & Pietras, 2008;Weatherly & Brandt 2004), persistence of gambling behaviour (Weatherly & Brandt, 2004), response latencies (Schreiber & Dixon, 2001) or preference (Haw, 2008). There is some evidence that that participants can be sensitive to varying RTPs, but one study showed that participants preferred slot machines with a higher RTP (Coates & Blaszczynski, 2013), and another study discovered that participants preferred slot machines with a lower RTP (Coates & Blaszczynski, 2014).…”

The near win effect on observing behaviour in simulated slot-machine gambling: The role of conditioned reinforcement

<p>Slot machines are a remarkably popular mode of gambling even though they are programmed to make a profit by paying out less money than is put in. One common feature of slot machines, which may increase the likelihood of persistent gambling in the face of this monetary loss, is the near win. This study’s aim was to investigate the conditioned reinforcing properties of near wins using an observing response procedure in the context of a simulated slot machine. In an observing response procedure, participants can use an observing button to produce a stimulus correlated with the availability of reinforcement (S+) or a stimulus correlated with no reinforcement or less reinforcement (S-). The percentage of observing responses made for each stimulus is thought to reflect the reinforcing efficacy of the reinforcer correlated with each stimulus. Experiment 1 successfully tested the procedure with an obvious reinforcer - wins - and found consistently more observing for the S+. In Experiment 2 and 3 the S+ was correlated with near wins, and in Experiment 2 only those with slot-machine experience had consistently more observing for the S+. Experiment 3 increased the probability of wins to enhance the reinforcing efficacy of near wins, but failed to find consistently more observing for the S+, regardless of slot machine or scratchie card experience. These results indicated that near wins are not conditioned reinforcers. However, participants tended to bet more following near wins than losses, which suggested that near wins may instead function as discriminative stimuli.</p>

“…These results suggest that investigating the effects of food cues and deprivation in dieters is warranted. Furthermore, assessing participants' prior experience with dieting and deprivation may be useful, as other research has demonstrated that experience with contingencies affects sensitivity to contingency manipulations (Brandt & Pietras, 2008).…”
