    ABSTRACT: The objective of the present study was to evaluate the effects of coffee intake with and withoutcaffeine on feeding behavior in rats. Sixteen rats was exposed to 2g, 3g, 4g and 5g of coffee withcaffeine and without caffeine diluted in 200ml of water. Subjects were assigned to 4 groups conformedby 2 females and 2 males each one. Groups 1 and 2 were exposed to coffee with caffeineand groups 3 and 4 to coffee without caffeine. Exposed to coffee for groups 1 and 3 was of ascendingform (2 g, 3 g, 4 g, and 5 g) and for groups 2 and 4 of descendent form (5 g, 4 g, 3 g and2 g). The experiment was divided in 9 phases. Phases 1, 3, 5, 7 and 9 lasted of 10 days, in eachone were provided 200ml of water and 50g food. Phases 2, 4, 6 and 8 lasted of 5 days; in eachone provided the concentrations of coffee and 50g food. The results showed that the low concentrationsof coffee registered a greater consumption in comparison with the high concentrations inboth conditions (ascending and descendent). On the other hand, coffee without caffeine was moreconsumed than coffee with caffeine.

    ABSTRACT: This study evaluated effects of nutritional information about fruits and vegetables consumption. Participants were 25 children between 3 and 5 years-old, which were exposed at high and low nutritional foods. Subjects were divided in two groups (experimental and control) and exposed to four phases. Experimental group received nutritional information about dietetic habits, nutritional facts and benefits of fruits and vegetables consumption. Results showed that nutritional information modified the eating behaviour. Non-nutritious food consumption diminished, but fruits and vegetables consumption not increased. Data suggest that nutritional information modifies eating behaviour development in preschoolers, but is necessary a suitable duration and frequency with adequate reinforced in house through model of parents.

In the first part, a revision of the beginnings of the psychophysic and experimental psychologyappears. Later, the most important contributions are characterized those studies thatinvolved the studies in psychology animal, structural and functional, finalizing with theWatson and Skinner´s behaviorist proposal as the method to study the psychologicalphenomena. Finally, we discussed the utility of the laboratory studies from the perspectiveof experimental analysis of behavior, emphasizing the reaches and development in theUnited States and diverse countries of Latin America
