1. 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

2. Schedule-induced behavior in humans: a study of the effects of the interval schedules with different requirements for reinforcement liberation / Indução de comportamentos em humanos: um estudo dos efeitos de esquemas de intervalo com diferentes requisitos para liberação de reforços
This study was designed in order to test the effects of different interval schedules of reinforcement in the induction of the behavior of peanuts consumption in humans during a game in the computer. Six adults aged between 20 and 42 years served as subjects. They were submitted to 30 minute sessions. There was 15 minutes in a waiting room where 120 grams of

3. The establishment of stimulus control over pairs of graphically similar letters and syllables: A comparison among trial and error, fading and stimulus shaping / Uma comparação entre procedimentos de estabelecimento de controle de estímulos entre pares de letras com grafias semelhantes e no reconhecimento de sílabas: tentativa e erro, fading e shaping de estímulos
The purpose of this study was to compare 3 procedures to establish stimulus control between graphically similar letters. The participants were 12 non literate children, ages 2 to 6.The children were first exposed to an identity matching to sample test with letters. Then, they were randomly assigned to 1 of 3 simple discrimination training procedures: trial a

4. Training and testing procedures of stimulus relations in Cebus apella / Procedimentos de treino e teste de relações entre estímulos em cebus apella
A aprendizagem complexa abrange o controle por relações abstratas após a exposição a relações diretamente treinadas. Neste trabalho, uma seqüência de experimentos investigou a aprendizagem de relações entre estímulos em dois macacos prego (Cebus apella) envolvendo o treino direto de relações de identidade, testes sucessivos de identidade genera

5. Investigação longitudinal dos efeitos de diferentes contingências com estímulos apetitivos e aversivos sobre o desamparo aprendido / Longitudinal research on the effects of different contingencies with appetitive and aversive stimuli upon learned helplessness
The learned helplessness hypothesis was put forward by Seligman &Maier in 1976 under the assumption of generality among all stimulus conditions, aversive or otherwise, and as an explanatory model of human depression. This proposition allowed for some experimental manipulations aimed at reversing the effect, using, among others things, positive reinforcement

6. Conhecimento em análise do comportamento: uma revisão dos artigos sobre controle de estímulos no Journal of Applied Behavior Analysis
Na análise do comportamento o conhecimento é produto da inter-relação entre análise básica, aplicada e conceitual, de forma que o produto seja uma unidade e não somente a soma destas três formas de se pesquisar. Muitos autores têm se preocupado com a integração principalmente entre pesquisas básica e aplicada, que vinham mostrando cada vez menos

7. The role of feedback in shaping neural representations in cat visual cortex
In the primary visual cortex, neurons with similar response preferences are grouped into domains forming continuous maps of stimulus orientation and direction of movement. These properties are widely believed to result from the combination of ascending and lateral interactions in the visual system. We have tested this view by examining the influence of deact

8. Shuffling of Genes Within Low-Copy Repeats on 22q11 (LCR22) by Alu-Mediated Recombination Events During Evolution
Low-copy repeats, or segmental duplications, are highly dynamic regions in the genome. The low-copy repeats on chromosome 22q11.2 (LCR22) are a complex mosaic of genes and pseudogenes formed by duplication processes; they mediate chromosome rearrangements associated with velo-cardio-facial syndrome/DiGeorge syndrome, der(22) syndrome, and cat-eye syndrome.

9. The influence of age on reproductive performance of the predatory ladybird beetle, Propylea dissecta
The influence of age on reproductive performance of an aphidophagous ladybird beetle, Propylea dissecta was examined using male and female beetles of varying ages (1–30 days) after a single mating stimulus. All the intermediate (10 to 20 days old) and old (30 days old) age females mated with all intermediate and old age males, while only a fraction (0.29%)
