The decline of response as a consequence of repeated stimulation is known as habituation. The goal of the present experiments was extending the knowledge about habituation of abdominal contractions in the pupa of Tenebrio molitor. Both experiments consisted of two phases. During Phase 1, all groups were exposed to a continuous stimulus (light in Ex...
Article
The present free operant conditioning experiments with rats examined the impact of manipulating different traits of an extinction-cue on ABA renewal. All rats were trained to perform an operant response (R1) for food in context A, and a different operant response (R2) in context B. Responses were then extinguished, R1 in context B and R2 in context...
Article
Previous research has shown that instrumental training can encourage the formation of binary associations between the representations of the elements present at the time of learning, that is, between the discriminative stimulus and the instrumental response (the S-R association), between the stimulus and outcome (the S-O association), and between t...
Article
Highlights  Undergraduate students were assessed on a videogame task.  Using three virtual contexts during extinction reduced ABA renewal of operant performance.  Conducting extinction in multiple contexts might enhances the generalization of the extinction learning to other contexts. Abstract In one experiment with human participants, we invest...
Article
Nowadays we can find a number of experiments that have showed the importance of learning in several situations related with survival of many animal species. For instance, knowledge acquired in the early stages of life could be crucial on the choice of egg-laying site. In this study we explored the influence of Pavlovian conditioning of silkworm lar...
Article
Changes in the temporal as well as the physical context produces the reappearance of extinguished behaviors. Furthermore, combining both kinds of contextual stimuli often causes greater levels of recovery. The current experiment explored the impact of extinction reminders on spontaneous recovery, renewal, and a combination of both effects using an...
Article
One of the most relevant phenomena both from a theoretical and clinical perspective is extinction. In particular, several researchers are interested in the response recovery effects from extinction. Reinstatement is an effect that has been proposed as a laboratory model to study relapse from extinction-based therapeutic treatments. We designed two...
Article
One of the most relevant behaviors in the life of some insects is oviposition, because reproductive fitness largely depends on the choice of egg-laying site. We report one experiment that explored the influence of Pavlovian conditioning on oviposition choices of the silkworm. Our results show that moths that jointly experienced an odor (conditioned...

La lectura es un proceso complejo en el que intervienen factores perceptivos, lingüísticos, cognitivos y neuropsicológicos. Algunos factores neuropsicológicos participan en el proceso lector desde su inicio, tales como los movimientos oculares que se realizan en la lectura, la motricidad y la lateralidad. El objetivo de este estudio fue evaluar la...
Poster
The Hopkins host selection principle (HHSP) states that insects prefer to oviposit on the host plant they consumed as larvae. Thus, the moth of the silkworm, which only eats mulberry leaves during the larvae phase, should prefer to lay the eggs close to the mulberry leaves. Hence, oviposition decisions can be influenced by larval experience. To exp...
Conference Paper
The Hopkins host selection principle (HHSP) states that insects prefer to oviposit on the host plant they consumed as larvae. Thus, the moth of the silkworm, which only eats mulberry leaves during the larvae phase, should prefer to lay the eggs close to the mulberry leaves. We designed an experiment with two objectives: 1) testing this principle in...
Article
Full-text available
Select literature regarding cue competition, the contents of learning, and retrieval processes is summarized to demonstrate parallels and differences between human and nonhuman associative learning. Competition phenomena such as blocking, overshadowing, and relative predictive validity are largely analogous in animal and human learning. In general,...
Article
Full-text available
Four experiments in human instrumental learning explored the associations involving the context that develop after three trials of training on simple discriminations. Experiments 1 and 4 found a deleterious effect of switching the learning context that cannot be explained by the context-outcome binary associations commonly used to explain context-s...
Article
It has been argued that the response recovery effects share a common mechanism. A possible way to test it is evaluating whether the techniques that impaired renewal would impair the other recovery effects as well. Two experiments with rats used a free operant procedure to explore whether an extinction-cue could prevent the spontaneous recovery and...

The goal of this study was to explore the extent to which several Psychology journals are similarly classified by both, a criterion based on the citation count, like the impact factor proposed by Journal Citation Reports, and another one related to the quality of the editorial process, like the compliance with the criteria proposed by the Latindex...

The goal of this study is to explore the extent to which several psychology journals may be similarly classified on the basis of citation count through the impact factor proposed by Journal Citation Reports and the hindex (Hirsch, 2005), against a given journal's compliance with the Latindex Catalogue criteria for assessing editorial quality. Using...

Two experiments were conducted to explore the associations involved in human predictive learning. Experiment 1 found that post-training devaluation of one of the outcomes by instructing participants that one of the attackers was indestructible, led to a significant decrease in participants' predictive responses to the cue that was initially followe...

An experiment was conducted using a human instrumental learning task with the goal of evaluating the mechanisms underlying the deleterious effect of context-switching on responding to an unambiguous stimulus when contexts are informative to solve the task. Participants were trained in a context-based reversal discrimination in which two iscriminati...

Nowadays the Impact Factor (IF) is used as a measure of the relevance or the quality of an institution, a research group or project, or a particular researcher's scientific production, regardless of the scientific field to which they belong. This paper shows a classification of the Spanish journals included in the Institute for Scientific Informati...

Para profundizar en el conocimiento del aprendizaje como proceso psicológico es necesario esclarecer cuáles son sus contenidos. En este sentido, durante parte del siglo pasado numerosas investigaciones se han dedicado a determinar qué asociaciones están implicadas tanto en el aprendizaje pavloviano como instrumental en animales no humanos, siendo m...

Numerosas investigaciones tanto en animales como en humanos muestran cómo en ciertas situaciones los estímulos contextuales pueden tomar un papel crucial en la recuperación de la información aprendida. Una de estas situaciones es cuando los contextos donde el aprendizaje tiene lugar poseen valor informativo, en cuyo caso toda la información aprendi...

Four experiments were conducted to study the contents of human instrumental conditioning. Experiment 1 found positive transfer between a discriminative stimulus (SD) and an instrumental response (R) that shared the outcome (O) with the response that was originally trained with the SD, showing the formation of an SD-O association. Experiment 2 found...

Full-text available
Transfer of behavioral control by a discriminative stimulus (SD) between different instrumental responses trained with the same outcome has been consistently observed in nonhuman animals, regardless of whether the discriminative stimulus and the instrumental response have undergone extinction. Based on this result, it has been proposed that extinct...

Four experiments were conducted to explore outcome-specific transfer from causal predictive judgments to instrumental responding. A video game was designed in which participants had to defend Andalusia from navy and air force attacks. First, they learned the relationship between two instrumental responses (two key on a standard keyboard) and two di...
