La discusión sobre las contribuciones de la neurociencia y en particular de la neurociencia cognitiva para la comprensión del comportamiento animal y humano, sigue siendo un tema en la agenda de la Psicología en general y del análisis experimental de la conducta en particular. El notable incremento en la producción investigadora de la neurociencia...

The present work aims improve our understanding of the boundaries of instructional control. It does so by solving contradictory results obtained on two different fields: Three studies conducted on the description-experience gap field, showing that instructions are neglected when personal experience is available, and several others conducted on the...

The purpose was to study whether re-exposure to an activity wheel with and without food restriction could generate a recurrence of the ABA model in rats. This model consists of exposing a group of rats to an experimental box with access to an activity wheel 23 hours a day, food available one hour a day and water ad libitum. During the 7-day experim...

This study explored learning and generalization of a third-order conditional discrimination. Two 8-year-old children learned two auditory–visual conditional discriminations in which they selected visual Japanese syllabic symbols in response to syllables spoken by the experimenter. Then, they learned a third-order conditional discrimination in which...

It has been suggested that achieving greater effectiveness in psychotherapeutic treatment requires analyzing what therapists actually do and say, how they do this and when it is done. Based on this approach, in this study we focused on the rules emitted by therapists, since providing rules is thought to be of fundamental importance in promoting eff...

In a serial reaction time task (SRTT), 121 university students divided into three experimental and one control groups responded differentially to four visual stimuli. The groups received a reward (money), punishment (cost of response) or visual feedback respectively and a control group linked to no consequences. The performance was evaluated by mea...

Providing and following rules has been considered an important factor in the effectiveness of psychological treatments; however, a conceptual clarification is needed of what is meant by issuing or following a rule and its application in the clinical setting. Based on a review of the original concept of rule-governed behavior, our purpose was to ext...

We evaluated the effects of two alcohol induction procedures on food-reinforced lever-pressing in rats. Nine outbreed Wistar rats were assigned to one of three groups. For all subjects a fixed-ratio (FR)11 food-reinforcement schedule was established. The induction group (IG) was exposed to alcohol at increasing concentrations over the course of 10...

When rats have been used to study the effects of alcohol on the learning and performance of sequences of variability and stereotypy, alcohol administration is often forced (e.g., intragastric, intraperitoneal) and the evaluation of these effects is usually measured in the short-term. On this basis, we evaluated the effects of chronic alcohol self-a...

Aunque se ha reconocido la importancia del uso de las reglas para el tratamiento de problemas psicológicos, aún se desconoce el papel que juega este tipo de verbalizaciones en el cambio clínico. Con el fin de contribuir al esclarecimiento del rol de las verbalizaciones en forma de regla, proponemos un análisis funcional de este tipo de verbalizacio...

The occurrence of spontaneous recovery in human spatial memory was assessed using a virtual environment. In Experiment 1, spatial memory was established by training participants to locate a hidden platform in a virtual water maze using a set of four distal landmarks. In Experiment 2, after learning about the location of a hidden platform, the platf...

Different methods were explored to induce alcohol intake in rats and subsequent cycles of food deprivation on the consumption of alcohol, food, water, and body weight when alcohol was available. Rats were assigned to four groups and a different procedure to induce alcohol intake was used over 12 days a) gradual forced alcohol (4% -10% v / v); b) fo...

La ciencia como práctica compartida tiene como funciones principales, por una parte, generar nuevo conocimiento y por otra, replantear o reformular en los casos en que sea necesario, algunos de sus fundamentos. Esto sólo es posible en la medida en que investigadores ya consolidados dan la oportunidad a que noveles estudiantes se incorporen al gremi...

Over the last 50 years, the variables established by B. F. Skinner in his work, Verbal Behavior (Skinner, 1957), have been taken into account in both empirical and theoretical research. Although historically the initial impact of Skinner's work was lower than expected, even in the areas most closely related to verbal behavior (e.g., naming, equival...

Forty children and forty youth were exposed to sequence of training of stereotypy or variability using matching-to-sample task. The stimuli were colored shapes indicating three sample-comparison relations (identity, similarity and difference). In stereotypy respond by repeating the same relation as in the previous trial was reinforced (i. e., alway...
