25. 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

26. Blank-comparison matching-to-sample reveals a false positive symmetry test in a capuchin monkey
A positive symmetry test result was obtained with a capuchin monkey that had previously exhibited virtually errorless AB and BA arbitrary matching-to-sample (MTS) with different stimuli. The symmetry test (BA) followed the acquisition of a new AB relation. It seemed possible, however, that the positive result could have occurred through the exclusion of prev

27. Effects of affective valence on a mixed Spatial Correspondence Task: a reply to Proctor (2013)
The present study investigated the influence of emotional valence on the spatial stimulus-key location correspondence effect in three experiments using the Affective Spatial Correspondence task (AffSCt). We initially reanalyzed the results of Conde et al. (2011) according to the model proposed by Proctor (2013). In that study, compatible and incompatible res

28. Exclusion performance in visual simple discrimination in dogs (Canis familiaris)
Choices based on exclusion have been investigated in different species because of its emergent nature, leading to evidence of rudimentary symbolic behavior in non-verbal organisms. Simple discrimination procedures provide a simple method to investigate exclusion performance, in which each trial consists of the simultaneous presentation of two stimuli, one wi

29. Temporal control in chained fixed-ratio, fixed-interval schedules
Four rats were subjected to chained fixed-ratio (FR), fixed-interval (FI) schedules of reinforcement (chain FR 5 FI). A FR schedule at one lever produced a discriminative stimulus (i.e., light) associated with an FI schedule of primary reinforcement (water) at the second response lever. The FR schedule was kept constant, whereas the FI length was changed fro

30. Interferential electrical stimulation improves peripheral vasodilatation in healthy individuals
BACKGROUND: Interferential electrical stimulation (IES), which may be linked to greater penetration of deep tissue, may restore blood flow by sympathetic nervous modulation; however, studies have found no association between the frequency and duration of the application and blood flow. We hypothesized that 30 min of IES applied to the ganglion stellate reg

31. Construção de um programa de ensino de pré-requisitos de leitura e escrita para pessoas com deficiência intelectual / Development of program to teach reading and spelling prerequisites for students with intellectual disabilities
Since its dawn, Behavior Analysis stood out in the search for ways of teaching complex repertoires to persons with intellectual retardation. Procedures built on stimulus equivalence have proved highly effective and economical, especially with regard to academic and symbolic skills. In Brazil, there is a tradition of successful research concerning the teachin

32. EstÃmulo mecÃnico na morfometria em mudas de Enterolobium contortisiliquum (Vell.) Morong / Mechanical stimulus as indicator of quality seedlings Enterolobium contortisiliquum (Vell.) Morong
This study aimed to quantify the effects induced by mechanical stimuli on the quality of seedlings Enterolobium contortisiliquum (Vell.) Morong. Treatments include five intensities of mechanical stimulation (0, 5, 10, 20 and 40 pushups) made daily for thirty days. The mechanical stimuli were initiated on December 20, 2011. Made by one-way passage of a struct

33. Desamparo aprendido e imunização em humanos: avaliação metodológica/conceitual e uma proposta experimental / Learned helplessness and immunization in humans: methodological/conceptual evaluation and an experimental proposal
The results of learned helplessness studies with humans have been inconsistent. This is probably due to the systematic contiguity between the end of the aversive stimulus and the immediately preceding response during the uncontrollability session, which mimics an accidental control condition. Three experiments were conducted to establish a procedure with ade

34. Avalanches e redes complexas no modelo Kinouchi-Copelli / Avalanches and complex networks in Kinouchi-Copelli model
The capacity of a sensory system in efficiently detecting stimuli is usually given by the dynamic range, a simple measure of the range of stimulus intensity over which the network is sensible enough. Many times biological systems exhibit large dynamic ranges, covering many orders of magnitude. There is no easy explanation for that, since individual neurons p

35. Topografias de controle de estímulos e equivalência de estímulos : variações paramétricas do procedimento de máscaras / Stimulus control topographies and stimulus equivalence: parametric variations of the blank procedure
A literatura de equivalência de estímulos tem mostrado dados robustos, porém com certa variabilidade de resultados entre participantes, com alguns formando classes prontamente e outros que não demonstram formação das classes esperadas. O emparelhamento com o modelo (MTS) é o procedimento comumente usado para verificar a formação dessas relações, n

36. Responder por exclusão em treinos de discriminação condicional com estímulos temporais por universitários / Choose by exclusion among university students during training of conditional discrimination with temporal stimuli.
O responder por exclusão vem sendo amplamente investigado e documentado com diferentes populações humanas. O padrão de escolher um estímulo indefinido condicionalmente a um modelo também indefinido, quando existem possibilidades de escolha definidas experimentalmente tem chamado a atenção de estudiosos interessados em processos simbólicos como a aqu
