OBJECTIVE: To evaluate the performance of adult young subjects in a Random Number Generation (RNG) task by controlling the response speed (RS). METHOD: Sixty-nine university students of both sexes took part in the experiment (25.05 ± 6.71 year-old). Participants were alloted into 3 groups which differed in RS rates to generate numbers: 1, 2 and 4 seconds to generate each number. A digital metronomer was used to control RS. Participants were asked to generate 100 numbers. The responses were mensured through Evans's RNG Index. RESULTS: There were statistically significant differences among the groups [F (3, 68) = 7.120; p < .05]. Differences were localized between 1 and 2 seconds (p = 0.004) and between 1 and 4 seconds (p = 0.006). No differences were observed between 2 and 4 seconds (p = 0.985). CONCLUSION: The present results suggest that the response speed in production of random numbers influences the performance of the Random Numbers Generation task.
As depressões secundárias freqüentemente remetem o psiquiatra a dificuldades maiores no tratamento do paciente, visto ser necessário uma abordagem mais ampla do caso para que a terapêutica alcance o efeito esperado sem piorar as doenças de base e sem interagir com outros medicamentos prescritos. Este artigo ilustra o caso de paciente com diabetes tipo II e hepatite C que, após fazer uso do interferon, apresentou sintomas depressivos. Estes só melhoraram, após diversas intervenções terapêuticas, com o uso do escitalopram. Também são discutidas as dificuldades no diagnóstico e tratamento da depressão e comorbidades psiquiátricas e clínicas de evolução crônica.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
