“…These limited results with a short follow-up (<8 days) are challenging to interpret and compare with the current findings. Here, as well as in cue-based memory updating studies [27,64,65], beneficial outcomes were evident at later time points but not during the extinction session or shortly after it. In contrast, many enhanced extinction studies report favorable effects during or soon after exposure to cues [57,59,66].…”

Tobacco use is the leading cause of preventable mortality worldwide. Since current smoking cessation aids show only modest efficacy, new interventions are needed. Given the evidence that stress is a potent trigger for smoking, the present randomized clinical trial tested whether stress could augment the effects of a memory updating (retrieval-extinction) intervention. Non-treatment seeking smokers (n = 76) were assigned to one of four conditions composed of either a stressful or non-stressful psychosocial challenge followed by either smoking or neutral cues. Ten minutes after this manipulation, all underwent a 60-minute extinction procedure during which they viewed smoking-related videos and images and manipulated smoking paraphernalia. Compared to participants who were not exposed to the laboratory stressor, the stressor-exposed groups exhibited greater psychophysiological responses during their intervention and greater decreases in cigarette use at two- and six-weeks follow-up independent of smoking cue exposure. Together, these findings suggest that the ability of stress to activate cigarette seeking processes can be exploited to decrease cigarette use. With replication, the stress-based intervention could become a novel strategy for decreasing cigarette use in non-treatment seeking smokers.Clinicaltrials.gov identifier: NCT04843969.

“…Recently, the study by Zandonai e coll. [26] innovatively applies VR-CET to smoking-associated memory. This method is based on the concept that exposure to related smoking stimuli would induce a positive consolidation of memory related to smoking.…”

“…ducing craving virtual settings, a VR-CET session was applied. It emerged that applying VR-CET after the reactivation of memory towards smoking is more effective in reducing craving than standard desensitization procedures [26]. A further example of the versatility of use of VR is represented in the study by Girard and coll.…”

“…Recentemente, lo studio di Zandonai e coll. [26] applica in modo innovativo la VR-CET alla memoria associata al fumo. Tale metodica si basa sul concetto che l'esposizione a stimoli fumo-correlati indurrebbe un consolidamento positivo sulla memoria connessa al fumo.…”

“…Nello specifico, una volta indotta la rievocazione della memoria per il fumo attraverso ambientazioni virtuali craving inducenti, è stata applicata una seduta di VR-CET. È emerso che applicare la VR-CET dopo la riattivazione della memoria verso il fumo, risulta più efficace nel ridurre il craving rispetto alle procedure standard di desensibilizzazione [26]. Un ulteriore esempio della versatilità di impiego della RV è rappresentato dallo studio di Girard e coll.…”

Dato l'enorme impatto sociosanitario che il fumo di sigaretta continua ad avere sulla popolazione mondiale, individuare nuove terapie per combattere il tabagismo è una necessità sempre attuale. Una possibile soluzione al problema proviene dal mondo tecnologico, grazie al quale è possibile sviluppare nuove sinergie con le terapie attualmente in uso. In particolare, la realtà virtuale è una tecnologia di recente sviluppo che bene si presta a essere impiegata anche in ambiente medico-sanitario, soprattutto in un settore complesso come le dipendenze comportamentali e da sostanze. Si sono quindi valutate le possibili applicazioni della realtà virtuale nello specifico contesto del tabagismo, soffermandosi sull'efficacia delle metodiche utilizzate e i possibili sviluppi in questo ambito.

The usage of virtual reality (VR) has been growing in many fields of research and therapy thanks to its immersive and gamified nature. Detection of the users’ subjective experience is thus essential for the effective personalization of content. Eye-tracking (ET) data and specifically gaze, in two-dimensional tasks, has been linked to value-based choices and emotional states. Therefore, here we aimed to develop a method for passive identification of subjective preferences based on ET data collected during a VR experience. For this purpose, we developed a naturalistic dynamic VR task where participants searched and looked at complex objects of pets and their control shapes that appeared in pre-defined locations in random order. At the end of the task, participants ranked their preference, valence, and arousal of the items they saw during the task. ET data was recorded using a built-in binocular eye-tracker within the VR headset. We found that the gaze behavior features of the median distance of gaze from the center of objects and the median gaze scan speed showed a significant interaction with object type (pets/shapes), as well as a significant positive relation to preference and valence rankings of pets. Our results suggest that these gaze behavior features could be used as passive biomarkers for detecting individual preferences and pleasantness, and in the future may enable successful personalization of VR content in real-time for various applications such as optimization of psychiatric diagnosis and treatment sessions.
