Derived generalization of attentional bias for laboratory-induced threat: Yes but.

There is laboratory evidence that fear conditioning underlies the emergence of attentional bias (AB) for threat. Our main objective was to test, for the first time, whether derived or symbolic responding contributes to the generalization of AB across non-conditioned stimuli. Participants were all university students ( = 86) with no pre-existing conditions.

Psychological inflexibility and valuing happiness: Dangerous liaisons.

Previous evidence has shown that excessive valuing happiness may relate to lower psychological wellbeing across cultures. Considering the lack of data with Spanish population, we examined the relation between tightly holding happiness emotion goals and subjective wellbeing in a sample of Spanish women, and explored the mediation role exerted by psychological inflexibility components (namely, cognitive fusion and experiential avoidance) in the relation between valuing happiness and subjective wellbeing. A female adult sample ( = 168) filled out measures of excessive valuing happiness, psychological inflexibility, positive affect, negative affect, and life satisfaction.

Academic Competence, Teacher-Student Relationship, and Violence and Victimisation in Adolescents: The Classroom Climate as a Mediator.

School violence is a serious social and public health problem prevalent worldwide. Although the relevance of teacher and classroom factors is well established in the literature, few studies have focused on the role of teacher perceptions in school violence and victimisation and the potential mediational role of classroom climate in this relationship. A total of 2399 adolescents (50% girls), aged between 11 and 18 years (M = 14.

School Violence towards Peers and Teen Dating Violence: The Mediating Role of Personal Distress.

School violence towards peers and teen dating violence are two of the most relevant behaviour problems in adolescents. Although the relationship between the two types of violence is well established in the literature, few studies have focused on mediators that could explain this empirical relationship. We departed from the evidence that relates anger, emotional distress and impaired empathy to teen dating violence and juvenile sexual offending, to explore the role of personal distress, i.

Differential outcomes training improves face recognition memory in children and in adults with Down syndrome.

Previous studies have demonstrated that the differential outcomes procedure (DOP), which involves paring a unique reward with a specific stimulus, enhances discriminative learning and memory performance in several populations. The present study aimed to further investigate whether this procedure would improve face recognition memory in 5- and 7-year-old children (Experiment 1) and adults with Down syndrome (Experiment 2). In a delayed matching-to-sample task, participants had to select the previously shown face (sample stimulus) among six alternatives faces (comparison stimuli) in four different delays (1, 5, 10, or 15s).

Improving delayed face recognition in Alzheimer's disease by differential outcomes.

Objective: Previous studies have demonstrated the benefit of the differential outcomes procedure (DOP) in human learning. In the present study we aimed to explore whether the DOP might also help to overcome the face recognition memory deficit commonly observed in Alzheimer's disease (AD) patients.

Method: A delayed matching-to-sample task was used.

Visual working memory in deaf children with diverse communication modes: improvement by differential outcomes.

Although visual functions have been proposed to be enhanced in deaf individuals, empirical studies have not yet established clear evidence on this issue. The present study aimed to determine whether deaf children with diverse communication modes had superior visual memory and whether their performance was improved by the use of differential outcomes. Severely or profoundly deaf children who employed spoken Spanish, Spanish Sign Language (SSL), and both spoken Spanish and SSL modes of communication were tested in a delayed matching-to-sample task for visual working memory assessment.

Differential outcomes aid the formation of categorical relationships between stimuli.

The differential outcome effect is when learning is enhanced through the application of different outcomes to different conditions of a task. Here we explore whether one difference in learning with differential outcomes is an enhanced categorisation of objects. We demonstrate that participants learning conditional discriminations are better able to identify previously unpaired objects as belonging to the same category when differential outcomes were used in learning these stimuli.

Enhancing recognition memory in adults through differential outcomes.

It has been widely demonstrated that the differential outcomes procedure (DOP) facilitates both the learning of conditional relationships and the memory for the conditional stimuli in animal subjects. For conditional discriminations in humans, the DOP also produces an increase in the speed of acquisition and/or final accuracy. However, the potential facilitative effects of differential outcomes in human memory have not been fully assessed.

Improvement of age-related memory deficits by differential outcomes.

Background: The differential outcomes procedure (DOP) has proved useful to improve discrimination learning in both animals and humans. Here we adapted DOP to assess its utility to overcome the memory loss commonly associated with normal aging.

Methods: In a delayed matching-to-sample task, subjects were exposed to a man's face, and after a delay, they were required to decide if the previously seen face was within a set of six men's faces.

Acquisition of schedule-induced polydipsia by rats in proximity to upcoming food delivery.

Food-deprived rats that receive intermittent delivery of small amounts of food develop excessive drinking--specifically, schedule-induced polydipsia (SIP). A main characteristic of SIP is its occurrence at the beginning of interfood intervals. The purpose of this study was to demonstrate that SIP can be developed toward the end of interfood intervals, in closer proximity to upcoming than to preceding food delivery.
