Skinner’s views about selection evolved. Leao and Neto show convincingly that his selectionism was at best nascent in the 1930s and 1940s. Their arguments persuade me that no concept of selection by consequences may be found in Skinner’s published writings in those decades.

The authors examine B. F. Skinner’s writings from the 1930s and 1940s to determine how early Skinner embraced selectionism. The authors conclude that despite an implicit commitment to selectionism during these two decades, on balance Skinner’s writings suggest a more traditional sense of antecedent, mechanistic causality based on necessity and temporal contiguity, and a stronger case can be made that Skinner’s selectionism emerged only later, in the 1950s. The present commentary generally supports the authors’ analysis, and interprets Skinner’s early writings, such as those arguing for the generic nature of stimuli and responses, as laying an important foundation for selectionism, rather than expressing a fully mature version of selectionism.

The purpose of the current study was to examine the effects of delivering a high-probability instructional sequence on generalized consumption of nonpreferred foods with similar properties to treatment foods. The participant was a 5-year-old, typically-developing child with a history of food selectivity. The participant was asked to complete each step of an instructional sequence in which the final step was consumption of a nonpreferred food. Praise was delivered after compliance to complete each step and a preferred food was delivered after compliance with the final step. The high-probability instructional sequence was effective in increasing consumption of nonpreferred foods and generalization was observed to nontarget foods with similar properties. The importance of tailoring procedures to treat food selectivity displayed by typically developing children is discussed.

El proposito del presente trabajo fue evaluar la utilidad del lenguaje de programacion libre Scratch para disenar y conducir experimentos conductuales en computadora. Scratch es un software de licencia libre, utilizable tanto en su version online como en version offline (Scratch 2.0), en sistemas operativos como Windows o Mac OS y dirigido principalmente a poblacion infantil para promover el desarrollo de habilidades en programacion mediante la creacion de videojuegos, animaciones, entre otras posibilidades. La programacion se basa en la construccion de conjuntos de bloques que controlan las acciones de los elementos que se disponen sobre un fondo y permiten la interaccion con el usuario del algoritmo programado a traves del monitor de la computadora y mediante los dispositivos perifericos de esta (teclado, raton o incluso extensiones). Se programo un procedimiento que consistio en elegir entre dos opciones que resultaban en “ganar” o “perder” a lo largo de una serie de ensayos en los que la probabilidad de ganar siguio una distribucion en forma de U invertida. El software permitio la programacion de todos los eventos experimentales, asi como el registro de las elecciones, latencias de los participantes, el numero de ensayos exitosos, entre otras variables.

Leao and Neto have presented an interesting and complex history relating to Skinner’s conceptual and empirical evolution of the notion of consequences selecting patterns of behavior. As these authors are careful to note, terms like “selectionism” and “determinism” (and I would add “mechanism”) have multiple uses in the language and thus attempting to provide anything like a clear picture of just how Skinner changed in his thinking about the nature of the operant over a decade or so of quite active work is more than a challenge.

D. C. Palmer
Early in Skinner’s professional career, he took an important step away from the psychological essentialism that pervades the field of psychology: He observed that the relationship between behavior and its consequences was most orderly when his analytical units embraced the variability that is implicit in all selection contingencies. The view that variability is fundamental, not accidental, is the central difference between selectionism and essentialism. One reason for pursuing analogies among different levels of selection is the extraordinary power of contingencies of selection to explain adaptive complexity in nature. Apparent exceptions to the analogy between behavioral and evolutionary development can be interpreted in terms of directed variation. As an example of directed variation, Skinner’s explicit exposition of the analogy between shaping and natural selection in 1953 might have been inspired, in part, by the work of the British biologist, J. W. S. Pringle (1951).
在斯金纳职业生涯的早期,他迈出了重要的一步,远离了心理学领域普遍存在的心理本质主义:他观察到,当他的分析单元接受了所有选择偶然性中隐含的可变性时,行为与其后果之间的关系是最有序的。认为可变性是基本的,而不是偶然的观点,是选择主义和本质主义之间的主要区别。在不同层次的选择中追求类比的一个原因是,选择的偶然性具有非凡的力量,可以解释自然界的适应性复杂性。行为发展与进化发展之间类比的明显例外可以用定向变异来解释。作为定向变异的一个例子,斯金纳在1953年对塑造和自然选择之间的类比的明确阐述,可能部分受到了英国生物学家J. W. S. Pringle(1951)工作的启发。

Experimental conditions similar to those described by Lieving and Lattal (2003) were used within two experiments to evaluate the resurgence of mands with humans. Two mands from the same operant class were trained with three participants with developmental disabilities during Experiment 1 and with two participants with developmental disabilities and a history of problem behavior during Experiment 2. The two mands were then placed on extinction. Both persisted, but showed different response strength during extinction. The mand with the weaker response strength was targeted for additional functional communication training and the alternative mand was placed on extinction. Following steady levels of occurrence of the targeted mand and no occurrences of the alternative mand, both mands were placed on extinction again. At least one instance of resurgence of the alternative mand occurred with every participant and resurgence of problem behavior occurred for both participants during Experiment 2.

An important aspect for the acquisition of instructional functions by a precontact description is the interaction of its relevance and specificity with the feedback frequency. Studies made in the area have focused its interest in the manipulation of the description’s Response (R) component; with the purpose of beginning with the assessment of the effects to manipulate Stimulus Situation (SE) component, and using a first order matching-to-sample task, 36 pre-graduate students were assigned to one of the nine experimental groups, that differ by the type of precontact description and the feedback frequency received. Results shows that participants that did not receive feedback, obtained the worse results, whereas those that received continuous feedback were superiors, being better those that received Specific and Non Pertinent precontact descriptions.
