Abstract: Executive functions (EFs) are essential in human functioning, and are an important field of study in neuropsychology. One of the most common disorders concerning EFs is the alteration in response inhibition, fundamental to an adequate behavior. This study aimed to show the initial normative data of 35 healthy subjects (22 women and 13 men, with a mean age of 42.60 years old [SD = 14.36]) in a free version of the Go/No-go task. We were able to identify a clear influence of the variable age in reaction time concerning response inhibition and attention.

Abstract: O objetivo deste trabalho foi avaliar o efeito de inseticidas no controle da mosca-branca (Bemisia argentifolii Bellows & Perring, 1994) na incidência do vírus-do-mosaico-dourado e na produtividade do feijoeiro. Utilizou-se de tratamento de sementes com imidacloprid ou thiamethoxam, e de pulveriza es de inseticidas, em intervalos semanais. O experimento foi realizado no campo, em área irrigada, em Petrolina, PE, em blocos ao acaso, com cinco tratamentos e quatro repeti es. Houve redu o significativa no número médio de ovos, de ninfas e de adultos da mosca-branca e na porcentagem de infec o pelo vírus-do-mosaico-dourado do feijoeiro. A produtividade nas parcelas tratadas variou de 1.930 a 2.405 kg/ha, enquanto na testemunha foi de 1.490 kg/ha. N o foi observada diferen a significativa entre os tratamentos, no número de vagens/planta e peso de 100 sementes.
