RESUMO
AIM: To conclude the characteristics of flash visual evoke potentials (FVEP), and pattern visual evoke potentials (PVEP) of the healthy school-age children.And to compare the two methods, in order to find the association of them, and to find the impact of sex, age, and the other biological variables.METHODS: A total of 101 healthy children were recruited (age from 5 to 14.4y, mean 8.27y).Each of them was underwent FVEP and PVEP examinations.Then the results were statistically analyzed by SPSS 13.0.RESULTS: The curves of PVEP are simple and stable, while FVEP waveforms are variable.The latency of P100 of females is shorter than males.However there was no significant difference for FVEP in sex control.To compare the parameters between the two hemispheres, the amplitude of P100 of left eyes were higher than the right side.FVEP showed no difference in the two hemispheres either.There was no significant difference for age-dependent decreased in neither PVEP nor FVEP.And in a regression analysis of the FVEP and PVEP, we could not find the inner connection of the two methods.CONCLUSION: Based on our research, there were no significant differences in age level or sex control in the period of school-age children.And there is no inner connection of the two methods.The differences between the PVEP and FVEP results might be due to the origin of these two responses.And these two stimuli should be used in a complementary manner not as alternative examinations.
RESUMO
Se realizó un estudio descriptivo de 110 estudiantes de primer año de la carrera de medicina en la Facultad de Ciencias Médicas No. 2 de Santiago de Cuba, desde enero hasta julio del 2014, con el objetivo de determinar algunas variables biológicas que pudieran estar relacionadas con los principales trastornos del sueño. La información fue procesada estadísticamente, con el empleo del porcentaje como medida de resumen y la aplicación de la prueba de la Χ² para valorar la posible asociación entre variables. En la serie se obtuvo que los trastornos del sueño más frecuentes fueran el insomnio, los ronquidos y las pesadillas, con predominio en las féminas; no obstante, en la mayoría de los alumnos el electroencefalograma resultó normal.

The information was statistically processed, with the use of the percentage as summary measure and the chi squared test to evaluate the possible association between variables. In the series it was obtained that the most frequent sleep dysfunctions were insomnia, the snoring and nightmares, with prevalence in the females; nevertheless, in most of the students the electroencephalogram was normal.

Esta análise teórica objetivou discorrer sobre a postura do analista do comportamento frente ao comportamento do indivíduo que possui o diagnóstico psiquiátrico de esquizofrenia, apresentando uma possibilidade de estudo desse fenômeno comportamental e de explicação do mesmo pautadas na ciência da análise do comportamento. Essa ciência possui uma abordagem empírica para entender e influenciar o comportamento do indivíduo. Uma breve análise crítica da atribuição causal às variáveis biológicas comumente usadas para explicação do quadro esquizofrênico é levantada, sem contudo desconsiderar a importância de tais variáveis para uma ciência do comportamento. Não se pretende com esta apresentação esgotar os temas. O aprofundamento das questões postas pode ser feito percorrendo-se a literatura citada.
This theoretical analysis aimed to discuss the stance of the behavior analyst regarding to a behavior of the individual who owns the psychiatric diagnosis of schizophrenia, presenting a possibility to study this behavioral phenomenon and explanation of it, guided by focused on the science of behavior analysis. This science has an empirical approach to understanding and influencing the behavior of the individual. A brief critical analysis of causal attribution to biological variables commonly used to explain the schizophrenic is lifted without disregarding the importance of these variables for a science of behavior. It is not intended by this presentation, exhaust the topics. The deepening of the questions posed can be done by scrolling to the literature cited.
