    Examining the Gambling-Related Harms, Gambling Disorder, and Player Characteristics of Jogo do Bicho (an Illegal National Lottery) in a Representative Sample of Brazilian Lottery Players
    (2024) KIM, Hyoun S.; SANCHES, Marcos; MARIANI, Mirella Martins de Castro; HODGINS, David C.; TAVARES, Hermano
    We investigated the demographics, gambling-related harms, and risk for gambling disorder (GD) associated with an illegal national lottery-type game called Jogo do Bicho that is culturally unique to Brazil in a sample of 5407 representative Brazilian lottery players. Participants reported on demographics, gambling behaviors, gambling-related harms, and GD. A total of 27.0% of the participants reported playing Jogo do Bicho in the past year. Jogo do Bicho was associated with greater risk of GD with 5.7% of current Jogo do Bicho players meeting diagnostic criteria. Jogo do Bicho was also associated with greater gambling-related harms. Older participants, males, individuals who self-identified as Black, and who were widowed were more likely to be current Jogo do Bicho players. Jogo do Bicho is a popular activity among legal lottery players in Brazil despite its illegal status and is associated with greater harms and increased risk of GD.

    Voluntary and Automatic Orienting of Attention in Children with Attention Deficit Hyperactivity Disorder
    (2021) MARIANI, Mirella Martins de Castro; LELLIS, Vera Rocha Reis; NOVAES, Rafael Angulo Condoretti Barros; SCHWARTZMAN, Jose Salomao; TEIXEIRA, Maria Cristina Triguero Veloz; CARREIRO, Luiz Renato Rodrigues
    Objective: Voluntary and automatic orienting of attention enable proper processing of environmental information. Few studies have assessed how this process varies during development in children with attention deficit hyperactivity disorder (ADHD). Methods: This study analyzed voluntary and automatic orienting in 30 children with ADHD and 30 age and sex matched controls (Control group-CG). Two experiments assessed voluntary and automatic orienting by recording reaction times (RT) to conditions in relation to temporal interval, spatial position, cue validity and age. The RT medians calculated for each condition and participant were analyzed using ANOVA to compare ADHD and CG. Results: Children with ADHD exhibited globally higher RT than the CG group. They also showed prejudices during the reorienting process and demonstrated adequate voluntary orienting for shorter intervals. In automatic task, there was no group interaction, expressing early facilitation, but not inhibition of return. Conclusion: These results identify correlations of ADHD and the children's age in relation to voluntary and automatic orienting of attention.
