In this research, a prepulse inhibition task was carried out in which subjects were treated with a psychostimulant, methylphenidate (MPH), acutely and chronically in a population of Wistar rats. The dataset contains all the data from a sample of 56 Wistar rats (females and males). These data include the prepulses, pulses and phase of the...

El condicionamiento evaluativo CE es una forma de aprendizaje en el que el emparejamiento sistemático de una estímulo neutro EC con otro estímulo afectivo EL produce un cambio en el valor hedónico del EC en la dirección efectiva del El con el que ha sido

In this paper, we explore the interactions between a psychiatrist, Adolf Meyer, and an architect, Grosvenor Atterbury, in the design of the Henry Phipps Psychiatric Clinic, and how the ideas of Meyer helped Atterbury to figure out the details of this new building. Although barely mentioned in the History of Psychology textbooks, Phipps Clinic...

Entre 1927 y 1962, H. S. Liddell y sus colaboradores desarrollaron un extenso programa de investigación relacionado con el estudio de las neurosis experimentales en distintas especies. A partir de la década de 1940 iniciaron una serie de trabajos en torno a su prevención y fue en este último ámbito en el que lograron captar más la atención de...

The role of context in the retrieval of learned information has been widely analyzed in the associative learning domain. However, evidence about the effect of context on flavor memory retrieval is more limited. We have carried out four experiments with rats testing for possible interactions between neophobia habituation and the context in which...

Se entrenó a 18 estudiantes en un procedimiento de igualación a la muestra de segundo orden en donde todos los estímulos consistían en figuras o palabras. EL primer estímulo muestra (estímulo muestra de segundo orden; EMSO) indicó una de tres relaciones: identidad, semejanza o diferencia entre un segundo estímulo (estímulo muestra de primer...

En este trabajo, en el que se emplean ratas como sujetos experimentales, ponemos a prueba la hipótesis según la cual el aprendizaje de preferencias adquiridas con respecto a sabores sin consecuencia nutritivas post-ingesta se rige por mecanismos de condicionamiento clásico (por ej., Fedorchak, 1997). Con este objetivo llevamos a cabo dos...

Traditional diagnostic scales are based on a number of symptoms to evaluate and classify mental diseases. In many cases, this process becomes subjective, since the patient must calibrate the magnitude of his/her symptoms and therefore the severity of his/her disorder. A completely different approach is based on the study of the more vulnerable...

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...

Frustration tolerance is a skill related to emotional regulation processes and is important insofar as it affects people's social relationships and even health. Low levels of frustration tolerance in children have been associated with a greater number of externalizing symptoms such as aggression or anger. Despite its importance, there are a...

Surprising violations of outcome expectancies have long been known to enhance the associability of Pavlovian cues; that is, the rate at which the cue enters into further associations. The adaptive value of such enhancements resides in promoting new learning in the face of uncertainty. However, it is unclear whether associability enhancements...

The concept of ADHD has changed widely through the history of mental health classification manuals. In the past three decades, the number of ADHD diagnoses has hugely increased worldwide. One of the reasons to explain this fact could be the lack of precision, differentiation and adjust of the criteria and indicators of this disease. Research...

An attention disturbance is a problem that affects many school-aged children. The assessment in children is usually report-based, and as a result, controversy surrounds the diagnosis. To solve this issue, the aim of this study was to develop a new tool to detect possible attention-related problems and impulsive behavior in 4- and 5-year-old...
