- Deep technologies and safer gambling: A systematic reviewPublication . Cardoso, Leonor G.; Barroso, Beatriz C. R.; Piccoli, Gloria; Peixoto, Miguel; Morgado, Pedro; Marques, António; Rocha, Carla; Griffiths, Mark D.; Queirós, Ricardo; Dores, Artemisa; Pereira da Silva Marques, António José; de Faria Távora Moreira Peixoto, MiguelDeep technologies combine engineering innovation and scientific findings to solve complex problems and are becoming particularly relevant to the gambling industry. With the global rise of gambling practices and the subsequent increase of gambling-related problems and disorders, deep technologies have emerged as a way to create safer online gambling environments. However, there is still limited knowledge regarding their applica bility and consequences. The present study systematically reviewed the existing literature on deep technologies in gambling environments, such as online casinos and betting platforms, and explored their potential benefits, risks, and effectiveness in promoting safer gambling experiences. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Searches were conducted in Web of Sci ence, PubMed, Scopus, EBSCO, and IEEE databases, and manually. A total of sixty-eight studies were included in the review. In general, four primary applications of deep technologies in online settings were found: (i) behavioural monitoring and feedback; (ii) predictive risk modelling; (iii) decision support and AI classifiers; and (iv) limit-setting/self-exclusion tools. They were primarily used to identify and classify problematic gambling, prompt individual action, regulate gambling behaviours, raise awareness of risk levels, promote responsible gambling practices, support research, interventions, and evaluate player protection initiatives. Together, the findings suggest that deep technologies offer ample opportunities to enhance gambler safety and reduce potential risks, although challenges may arise from their implementation, such as privacy and ethical concerns, malicious data use, misclassification of risk levels, and difficulties in large-scale application. Limitations and directions for future studies are discussed
- Inventory of sensory, emotional, and cognitive reserve (SECri): Proposal of a new instrument and preliminary dataPublication . Pinto, Joana O.; Vieira, Isabel; Barroso, Beatriz C. R.; Peixoto, Miguel; Pontes, Diogo; Peixoto, Bruno; Dores, Artemisa R.; Barbosa, FernandoA new model of reserve, the Sensory, Emotional, and Cognitive Reserve (SEC) model, has beenrecently proposed, but so far this model has not been operationalized in instruments to evaluatethe different domains of the reserve. This study introduces the SEC reserve inventory (SECri) alongwith preliminary data obtained from a study involving 57 adults, aged 35 and older. The SECriassesses the SEC domains using specific proxies: (a) sensory reserve (SR) through sensory acuity andsensory perception proxies; (b) emotional reserve (ER) through life events, resilience, and emotionalregulation proxies; and (c) cognitive reserve (CR) through education, occupation, socioeconomicstatus, bilingualism, leisure activities, and personality traits proxies. Key features of SECri includeself- and informant-report forms, fine-grained response scales, and the evaluation of reservedevelopment across the lifespan. Findings on the acceptability, convergent validity between SECridomains and validated tests for the same constructs, internal consistency of each domain, andpredictive validity of Montreal Cognitive Assessment scores support further research with thisinventory. Future studies should consider determining SECri’s psychometric properties in clinical andsubclinical conditions to evaluate its prognostic value in cases of neurocognitive decline.
- Methylphenidate and P300 in attention deficit hyperactivity disorder: A systematic review and meta-analysisPublication . Barroso, Beatriz C. R.; Mendonça, Fabiana; Mazer, Prune; Prata, Catarina; Pinto, Joana O.; Mazer, Prune; Pinto, Joana OMethylphenidate (MPH) is a stimulant medicine often used to treat attention deficit hyperactivity disorder (ADHD), as it may positively affect behaviour and brain activity. This work aims to systematise the current literature about the effects of MPH on the amplitude of P300 in individuals with ADHD. A systematic review and meta-analysis of empirical studies measuring P300 amplitude and comparing MPH administration to either a pre-MPH condition or healthy controls was conducted, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Our results revealed no overall (n = 13) significant differences between individuals diagnosed with ADHD and medicated with MPH and controls. Although, a moderation analysis by region found differences between both groups on frontal sites. When comparing the pre- and post-effects of MPH on the same individuals (n = 17), it appears that P300 amplitude tends to increase post-administration in central and posterior regions. In this second meta-analysis, a moderation by task revealed a larger effect size for go/no-go. In general, MPH was found to increase P300 amplitude in ADHD, somewhat normalising this aspect of their brain activity. The main limitations of the included studies are the insufficiently explained dosages and the skewness for male participants. Future research directions are discussed.
