1. Assessing restricted stimulus control in typically developing preschool children and bees (Melipona quadrifasciata)
This study established a simple simultaneous discrimination between a pair of two-element compound visual stimuli in children (Experiment 1) and bees (Melipona quadrifasciata, Experiment 2). The contingencies required discriminative control by the compound and the question was whether the accurate stimulus control reached at this level would hold for each in

2. Restricted stimulus control in stimulus control shaping with a capuchin monkey
Teaching the first instances of arbitrary matching-to-sample to nonhumans can prove difficult and time consuming. Stimulus control relations may develop that differ from those intended by the experimenter-even when stimulus control shaping procedures are used. We present, in this study, efforts to identify sources of shaping program failure with a capuchin m

3. Anti-inflammatory polysaccharides of Azadirachta indica seed tegument
Azadirachta indica A. Juss., Meliaceae, or Indian neem is a plant used to treat inûammatory disorders. Total polysaccharide (TPL) and FI (fractioned by ion exchange chromatography) from the seed tegument of A. indica were evaluated in models of acute inflammation (paw edema/peritonitis) using Wistar rats. Paw edema (measured by hydroplethysmometry) was indu

4. Equivalência de estímulos e generalização recombinativa no seguimento de instruções com pseudofrases (verboobjeto) / Stimulus equivalence and recombinative generalization of instructionfollowing with pseudo-phrases (action-object)
An important issue in the field of verbal behavior is how a person understands and learns to behave according to verbal commands or instructions. The stimulus equivalence paradigm, as a model of symbolic behavior, may explain the origins of the comprehension of instructions. Following new instructions can result from the recombination of subunits of previous

5. Sensory response of the egg parasitoid Telenomus podisi to stimuli from the bug Euschistus heros.
The objective of this work was to study the foraging behavior of Telenomus podisi Ashmead (Hymenoptera: Scelionidae) in the presence of stimuli from its host, Euschistus heros (Heteroptera: Pentatomidae). The stimuli selected were: egg mass; virgin males and females; volatile extracts of sexually mature males and females; components of male sex pheromone; a

6. Avaliação do tipo de resposta requerida e do procedimento de ensino no estabelecimento de controle de estímulos compostos
Several factors may influence behavior control by just one or all aspects of a multidimensional stimulus. The present study investigated the effects of the response required during discriminative training of compound stimuli. Six 4 years old kindergarten children participated. All children were exposed to 3 conditions of simple simultaneous discrimination tr

7. Padrões de aquisição de discriminação condicional durante a emergência do controle por unidades verbais mínimas na leitura em crianças com autismo e desenvolvimento típico / Patterns of conditional acquisition of discrimination during the emergency control units for minimum sum in reading in children with autism and typical development
Study 1 of this work aimed to evaluate, in children with typical development, possible controls of stimuli involved in the process of acquisition of control by minimal verbal units. Investigation took place during the training sessions of conditional discrimination of compound stimuli (written words), and during the tests that evaluated the emergence of cont

8. Procedimento go/no-go com estímulos compostos e relações emergentes em pombos / Go/no-go procedure with compound stimuli and emergent relations in the pigeon
A emergência de relações não diretamente treinadas e a formação de classes de estímulos equivalentes têm sido demonstradas após treinos com o procedimento matching-to-sample em humanos. Entretanto, estudos com não-humanos têm encontrado dificuldade em demonstrálas. Estudos que utilizaram procedimentos alternativos ao matching-to-sample com pombos

9. Go/no-go procedure with compound stimuli and emergent conditional relations in children with autism / Procedimento go/no-go com estímulos compostos e relações condicionais emergentes em crianças com autismo
O procedimento matching-to-sample (MTS) tem sido amplamente utilizado para o estabelecimento de relações condicionais emergentes. Nesse procedimento, respostas de escolha são emitidas em diferentes localizações. Tal característica pode favorecer o estabelecimento de um controle inadvertido pela localização. No procedimento go/no-go com estímulos com

10. Efeitos de estímulos conseqüentes específicos sobre a emergência de leitura recombinativa / Effects of specific consequences upon the emergence of recombinative reading
Recombinative reading is the ability of reading under the control of smaller verbal units. This phenomenon is investigated through the training, in MTS, of dictated and printed words; and tests of reading with new words. The results of these experiments had varied in the literature. The most effective procedures are those in which the smaller units are direc

11. The effects of variable interval schedule on preference and liquid consumption by rats subjected to chronic mild stress / Efeitos do esquema de intervalo variável na preferência e no consumo de líquidos apresentados por ratos submetidos ao chronic mild stress
The Chronic Mild Stress (CMS) is an experimental animal model of depression induced by the exposure of rats to a set of moderate and uncontrollable aversive stimuli in a long and uninterrupted period of time. The purpose of this study was to investigate the relationship between performance in variable interval schedule of behavior and exposure to the protoco

12. Superseletividade: efeito do requisito de resposta e do tempo de exposição ao estimulo
The organisms are surrounded by several physical stimuli that may affect their behaviors. In traditional psychology, attention explains why the organism is sensitive to only part of the environment. The Experimental Analysis of Behavior searches for past and present environmental variables that influence stimulus control over behavior. Overselectivity or res
