- Abstract
Pavlovian-to-Instrumental Transfer (PIT) effect, described as the promotion or discouragement of instrumental behavior by appetitive or aversive Pavlovian conditioned stimuli, plays an important role in the development and maintenance of addictions. Substance use disorders studies have shown the behaviors of addicted individuals are more susceptible to the influence of Pavlovian cues than those who recreational use. The transfer may be related to stimulus-response associations that are insensitive to outcome value. Besides, incentive salience attribution makes addiction cues transformed into "wanted" stimuli that influence behavior. Evidence for PIT effects in Internet gaming disorder (IGD) remains insufficient. The adapted PIT paradigm in this study examined effect of monetary instrumental behavior by monetary Pavlovian cues (specific PIT effects) and internet game cues (general PIT effects). The behavioral changes following outcomes devaluation were measured. A total of 42 adults with IGD (18 females, Mage = 22.29 ± 2.96) and 38 healthy control (HC) participants (16 females, Mage = 22.92 ± 2.88) were included. The results showed participants with IGD have stronger specific PIT and general PIT effects, compared with HC. Specificly, inhibitory instrumental behavior of participants with IGD is affected by appetitive cues. The general PIT effect was only correlated with liking for game cues in HC group, which may reflect the separation between liking and wanting of addictive cues in participants with IGD. Although the devaluation sensitivity did not differ in the two groups, sensitivity was negatively correlated with the degree of addiction in participants with IGD. In conclusion, participants with IGD have a greater deviation in instrumental behavior than HC, which may be related to the development and maintenance of addiction.
