Habituation is defined as a decline in responding to a repeated stimulus. After more than 80 years of research, there is an enduring consensus among researchers on the existence of 9–10 behavioral regularities or parameters of habituation. There is no similar agreement, however, on the best approach to explain these facts. In this paper, we demonstrate that the Sometimes Opponent Processes (SOP) model of stimulus processing accurately describes all of these regularities. This model was proposed by Allan Wagner as a quantitative elaboration of priming theory, which states that the processing of a stimulus, and therefore its capacity to provoke its response, depends inversely on the degree to which the stimulus is pre-represented in short-term memory. Using computer simulations, we show that all the facts involving within-session effects or short-term habituation might be the result of priming from recent presentations of the stimulus (self-generated priming). The characteristics involving between-sessions effects or long-term habituation would result from the retrieval of the representation of the stimulus from memory by the associated context (associatively generated priming).

A substantial corpus of experimental research indicates that in many species, long-term habituation appears to depend on context–stimulus associations. Some authors have recently emphasized that this type of outcome supports Wagner’s priming theory, which affirms that responding is diminished when the eliciting stimulus is predicted by the context where the animal encountered that stimulus in the past. Although we agree with both the empirical reality of the phenomenon as well as the principled adequacy of the theory, we think that the available evidence is more provocative than conclusive and that there are a few nontrivial empirical and theoretical issues that need to be worked out by researchers in the future. In this paper, we comment on these issues within the framework of a quantitative version of priming theory, the SOP model.

Han pasado 16 años desde el nacimiento de la revista KEPES, por lo que ha sido necesario detenerse en el camino para hacer un recuento histórico de lo que la revista ha desarrollado. El objetivo del presente estudio se basa en la documentación y análisis cuantitavo del contenido y la historia de la revista KEPES. Se ha creado una base de datos con 269 documentos, compuesto por los 20 volúmenes de la revista (2004-2019), a los cuales se les ha realizado diversos estudios cienciométricos. Utilizando indicadores bibliométricos y de relación (Lawani, Subramanyam y el coeficiente de colaboración), los resultados indican que la revista KEPES se ha comportado como una revista masculina, nacional, principalmente de autorías individuales, primando históricamente el ensayo como tipo de escrito para la divulgación del conocimiento en idioma español; con redes de colaboración locales y acotadas. Si bien sus índices de colaboración han aumentado progresivamente, al igual que la estandarización del formato artículo científico, la idea de vincular Colombia con el mundo aún sigue siendo una tarea pendiente. Este análisis permite presentar la historia y tendencia de la revista de autores y relaciones.

The new SARS-CoV-2 coronavirus has brought with it an increase in the use of digital platforms and an exponential increase in the number of scientific papers worldwide. The purpose of this study is to show a global overview of the digital transformation from 1975 to the present (2021). The main collection of the Web of Science database was used to retrieve global scientific production on digital transformation. Bibliometric indicators of production, visibility, impact, and collaboration were analyzed to assess research progress on the topic. The results show that digital transformation is a construct of recent development, increasingly relevant and transdisciplinary, with a clear growth after the declaration of the global COVID-19 pandemic.
