The aim of this study was to evaluate whether emergent conditional relations could be established with a go/no-go procedure using compound abstract stimuli. The procedure was conducted with 6 adult humans. During training, responses emitted in the presence of certain stimulus compounds (A1B1, A2B2, A3B3, B1C1, B2C2, and B3C3) were followed by reinforcing(More)
We report a study with sixteen low-SES Brazilian children that sought to establish a repertoire of relations involving dictated words, printed words, and corresponding pictures. Children were taught: (1) in response to dictated words, to select corresponding pictures; (2) in response to syllables presented in both visual and auditory formats, to select(More)
In general terms, establishing operations can be defined as environmental events that alter the reinforcing effectiveness of a stimulus, as well as evoke all behavior that, in the past, has been followed by such a stimulus. The concept seems to describe, in behavioral terms, what is usually called motivation. The present paper is an attempt to didactically(More)
Formal and functional analyses of verbal behavior have been often considered to be divergent and incompatible. Yet, an examination of the history of part of the analytical approach used in Verbal Behavior (Skinner, 1957/1992) for the identification and conceptualization of verbal operant units discloses that it corresponds well with formal analyses of(More)
The objective of this work was to evaluate the changes in microbial biomass C, N and P due to the application of pig slurry under different soil tillage systems. The experiment was established in a clayey Oxisol, Eutrophic Red Latossol in Palotina, PR. Different quantities of pig slurry (0, 30, 60 and 120 m3 ha-1 year-1) were applied to the soil prior to(More)
The production of verbal operants not previously taught is an important aspect of language productivity. For Skinner, new mands, tacts, and autoclitics result from the recombination of verbal operants. The relation between these mands, tacts, and autoclitics is what linguists call analogy, a grammatical pattern that serves as a foundation on which a speaker(More)
Bloomfield's "Linguistics as a Science" (1930/1970), Language (1933/1961), and "Language or Ideas?" (1936a/1970), and Skinner's Verbal Behavior (1957) and Science and Human Behavior (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities between the two(More)
