13. 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

14. Effects of simple discrimination training on identity match-to-sample performance of an capuchin monkey (Cebus apella) / Efeito do treino de discriminações simples sobre o repertório de pareamento ao modelo por identidade de um macaco-prego (Cebus apella)
This paper reports an experiment training to verify the function of simple simultaneous discrimination training with pairs of stimuli on identity match-to-sample performance with the same stimuli. An infant capuchin monkey with experience with identity match-to-sample served as subject. It was investigated how much training with a Repeated Shift of Simple Di

15. 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

16. 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

17. Desempenho de crianças em testes sensoriais discriminativos e afetivos com escalas hibridas ilustradas. / The performance of children in discriminative and affective sensory tests with illustrated hybrid scales.
In both developed and emerging countries, children represent a significant part of the consumer market, a market which, due to globalization, has become extremely competitive and avid for novelties. As the number of products destined for the child food market increases and the role of the child in the decision to buy also increases, sensory evaluations carri

18. Stimulus equivalence with combined procedures and phonological consciousness in generalized reading acquisition / Equivalência de estímulos com procedimento combinados e consciência fonológica na aquisição da leitura generalizada
Equivalence class formation among pictures and spoken and printed words promotes reading with comprehension, but it does not establish the discriminative control by all the units of the word (letters and syllables). The application of combined special procedures (copy, dictation and oralization - fluently and spelled) while the teaching the conditional relat

19. Um procedimento para medir o estabelecimento de controle de estímulos em uma discriminação simples, baseado em Touchette (1971)
ABSTRACT Behavior analysts interpret attention as a case of operant stimulus control. Therefore the study of the variables and procedures that promote discrimination are taken as important if one is interested in attention. This interpretation guide many experimental studies on discrimination where experimental concern was the implementation of effective pro

20. O estabelecimento da função discriminativa de respostas e sua participação de classe de estímulos equivalentes
O presente estudo foi uma replicação de Dymond e Barnes (1994). Seu objetivo foi verificar se (1) o estabelecimento de um padrão de respostas como estímulo discriminativo para outras respostas de um individuo tornaria a resposta (como SD)_membro de uma classe de estímulos equivalentes da qual faz parte um estímulo sistematicamente pareado com a respost

21. Ensinando auto-conhecimento? o estabelecimento de uma resposta de auto-discriminação (Dymond e Barnes, 1994)
The present study aimed at the acquisition of responses of self - discrimination, involving previous behavior as discriminative stimulus for subsequent responding. Dymond and Barnes (1994) experiment was partially replicated. Seven young adults were submitted to 3 experimental phases. Each phase was comprised of 20 trial-blocks of two successive tasks, perfo

22. A produção de variabilidade de respostas pelo reforçamento de mudanças na dimensão duração
The environment is constantly changing, so that variability is a feature of behavior of fundamental importance for the behavior of organisms. Selection only exists because the responses of an organism are never identical. The study of variability can contribute with the comprehension of important processes like the emergence of new behavior, complex behavior

23. DESEMPENHO VERBAL DE PRE-ESCOLARES EM SITUACAO DE TESTE E DE BRINQUEDO / Text not informed by the author
This work consists of 3 studies, having as a general objective the analysis of the verbal behaviour of kindergarten children playing and being tested. The first study had the objective of verifying if the order of the presentation of a picture and three series of planks influenced the. verbal behaviour. Fourth eight children were tested, four, five and six y

24. Discriminative Stimulus Effects of 1-(2,5-Dimethoxy-4-methylphenyl)-2-aminopropane (DOM), Ketanserin, and (R)-(+)-α-(2,3-Dimethoxyphenyl)-1-[2-(4-fluorophenyl)ethyl]-4-pipidinemethanol (MDL100907) in Rats
Very little is known about constitutive activity in vivo. This study examined whether constitutive activity and inverse agonism contribute to discriminative stimulus effects of drugs acting at serotonin (5-HT)2A receptors. Rats were trained to discriminate between saline and either 0.56 mg/kg 5-HT2 receptor agonist 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopro
