History of psychology has been an extremely active field for many years in Spain. Both the great expansion of psychological studies and the inclusion of history as a compulsory subject in the psychology curriculum are crucial factors helping to understand the current state of affairs. The aim of this paper is to provide a survey of the work done in this area over the last decade, covering research, teaching, and institutional developments. The study includes consideration of aspects such as main research lines, major theoretical and methodological trends, teaching materials, relevant archives and exhibits, and significant websites.
This work presents a critical analysis of Pavlov's influence that goes beyond the conventional view: that which reduces his influence in American psychology to the behaviorism of Watson and Hull. In order to understand the nature of the Russian physiologist's influence in American psychology, we propose a distinction between three approaches to it: 1) the symbolic approach, on representing a model of the possibility of constructing an objective psychology; 2) the methodological approach, given the importance of the technique of conditional reflexes; and 3) the theoretical approach, which is derived from his theory of higher nervous activity. This perspective permits us to suggest that most of Pavlov's influence on behaviorism was of a symbolic and methodological nature-though the methodological influence also reached other authors that did not belong to the behaviorist traditions, as was the case of Mateer. As far as the theoretical influence is concerned, our work proposes that it is more visible in authors such as Gantt and Liddell, or even in authors such as Boldirev, Director of the Pavlovian Laboratory at the Battle Creek Sanitarium in Michigan. The case of Gantt is especially interesting because, in addition to his important contributions, he played an essential role in the foundation of the Pavlovian Society, and the journal Conditional Reflex. What our work proposes is that to understand the nature of Pavlov's influence in American psychology it is necessary to take into account the very characteristics of that psychology: its pragmatic interests, its methodological rigor, the dominant systems of neo-behavioral theory and the changes that occurred after the Second World War. Keywords: Pavlov, American psychology, behaviorismEn el presente trabajo se realiza un análisis crítico de la influencia de Pavlov que va más allá de su visión convencional: aquélla que reduce su influencia en la psicología americana al conductismo de Watson y Hull. Para entender la naturaleza de la influencia del fisiólogo ruso en la psicología norteamericana proponemos distinguir entre tres sentidos de la misma: 1) el simbólico, al representar un modelo de la posibilidad de construir una psicología objetiva; 2) el metodológico, por la importancia de la técnica de los reflejos condicionales; 3) el teórico, que se deriva de su teoría de la actividad nerviosa superior. Esta perspectiva nos permite sugerir que la mayor parte de la influencia de Pavlov sobre el conductismo fue de carácter simbólico y metodológico, aunque la influencia metodológica también alcanzó a autores que no pertenecieron a las tradiciones conductistas como fue el caso de Mateer. En lo que concierne a la influencia teórica, nuestro trabajo propone que es más visible en autores como Gantt y Liddell, o en otros menos conocidos como Boldirev, director de un laboratorio pavloviano en el Battle Creek Sanitarium de Michigan. El caso de Gantt nos parece de especial interés porque además de sus importantes contribuciones, jugó un papel esencial en la fundación de la Pavlov...
Recent studies support the idea that stimulus processing in latent inhibition can vary during the course of preexposure. Controlled attentional mechanisms are said to be important in the early stages of preexposure, while in later stages animals adopt automatic processing of the stimulus to be used for conditioning. Given this distinction, it is possible that both types of processing are governed by different neural systems, affecting differentially the retrieval of information about the stimulus. In the present study we tested if a lesion to the dorso-lateral striatum or to the medial prefrontal cortex has a selective effect on exposure to the future conditioned stimulus (CS). With this aim, animals received different amounts of exposure to the future CS. The results showed that a lesion to the medial prefrontal cortex enhanced latent inhibition in animals receiving limited preexposure to the CS, but had no effect in animals receiving extended preexposure to the CS. The lesion of the dorso-lateral striatum produced a decrease in latent inhibition, but only in animals with an extended exposure to the future conditioned stimulus. These results suggest that the dorsal striatum and medial prefrontal cortex play essential roles in controlled and automatic processes. Automatic attentional processes appear to be impaired by a lesion to the dorso-lateral striatum and facilitated by a lesion to the prefrontal cortex.
D2 receptor had a relevant role on retrieval processes of pre-exposure learning, while D1 receptor was related with the contextual control of conditioning.
In 1913, the Anthropoid Station for psychological and physiological research in chimpanzees and other apes was founded by the Royal Prussian Academy of Sciences (Berlin) near La Orotava, Tenerife. Eugene Teuber, its first director, began his work at the Station with several studies of anthropoid apes' natural behavior, particularly chimpanzee body language. In late 1913, the psychologist Wolfgang Köhler, the second and final director of the Station, arrived in Tenerife. During his stay in the Canary Islands, Köhler conducted a series of studies on intelligent behavior in chimpanzees that would become classics in the field of comparative psychology. Those experiments were at the core of his book Intelligenzprüfungen an Menschenaffen (The Mentality of Apes), published in 1921. This paper analyzes Köhler's experiments and notions of intelligent behavior in chimpanzees, emphasizing his distinctly descriptive approach to these issues. It also makes an effort to elucidate some of the theoretical ideas underpinning Köhler's work. The ultimate goal of this paper is to assess the historical significance of Köhler's book within the context of the animal psychology of his time.
