Anxiety is a common affective state, characterized by the subjectively unpleasant feelings of dread over an anticipated event. Anxiety is suspected to have important negative consequences on cognition, decision-making, and learning. Yet, despite a recent surge in studies investigating the specific effects of anxiety on reinforcement-learning, no…

In tutoring systems, a pedagogical policy, which decides the next action for the tutor to take, is important because it determines how well students will learn. An effective pedagogical policy must adapt its actions according to the student's features, such as knowledge, error patterns, and emotions. For adapting difficulty, it is common to…

The use of mindfulness as a tool to improve mental health has received increased attention. Schools provide ideal environments for short-term prevention and skill development for mental health. Further, teachers can promote and reinforce students' daily use of mindfulness. This study explored the effects of a short-term group mindfulness-based…

Background: Needle phobias are common in children and adults worldwide. One effective intervention for this phobia is exposure therapy where a participant is gradually exposed to increasing levels of the fear-evoking stimulus while differential reinforcement is applied. This intervention, however, may be difficult to implement with some medical…

The School Refusal Assessment Scale--Revised (SRAS-R) is a self-report measure designed to assess four functional factors of school refusal behavior: avoidance of stimuli that provoke negative affectivity (Factor I), escape from aversive social and/or evaluative situations (Factor II), pursuit of attention from significant others (Factor III), and…

Selective mutism is a relatively uncommon, yet significantly impairing anxiety disorder that causes difficulties in young children when communicating in social situations (such as school) even though they speak normally when they are comfortable (such as at home). Early childhood educators play a unique role in helping to identify selective…

Methylphenidate (MPH), introduced more than 60 years ago, accounts for two-thirds of current prescriptions for attention deficit hyperactivity disorder (ADHD). Although many studies have modeled MPH's effect on executive function, almost none have directly modeled its effect on long-term memory (LTM), even though improvement in LTM is a…

Safety signals provide "relief" through predicting the absence of an aversive event. At issue is whether these signals also act as instrumental reinforcers. Four experiments were conducted using a free-operant lever-press avoidance paradigm in which each press avoided shock and was followed by the presentation of a 5-sec auditory safety…

Specific phobias are among the most common anxiety disorders, especially in children. Unfortunately, a paucity of literature exists regarding the treatment of specific phobia in young children, despite the knowledge that traditional techniques (i.e., cognitive-behavioral therapy [CBT]) may not be practical. Therefore, the purpose of this article…

Tics are rapid, repetitive, stereotyped movements or vocalizations that arise from neurobiological dysfunction and are influenced by environmental factors. Although persons with tic disorders often experience aversive social reactions in response to tics, little is known about the behavioral effects of such consequences. Along several dimensions,…

A number of studies have demonstrated the efficacy of brief cognitive-behavioral interventions for treating childhood nighttime fears. The purpose of the present study is to determine whether behavior changes could be initiated and maintained with home monitoring and reinforcement alone. Sixteen children, ages 6 to 11, with severe, disruptive…

Earlier studies on human avoidance learning showed that an avoidance response reduces the expectancy that a warning stimulus (WS) will be followed by an unconditioned stimulus (US). This modulation can transfer to WSs with which the avoidance response did not occur in the past. Recent studies suggest that transfer of modulation is selective in…

Traditional behavioral plans for children with Asperger syndrome often neglect what they need to learn to manage their anxiety and the underdeveloped skills that contribute to their anxiety. School personnel often identify a desirable target behavior and try to reinforce it through rewards (stickers, praise, etc.), which usually does not work.…

Undergraduates participating in experiments late in the semester generally perform more poorly on demanding tasks and withdraw more often than those participating early. To investigate effects of task aversiveness, some participants were instructed to choose brief cartoon reinforcement with a long time-out while others were instructed to choose…

Behavioral inhibition is a temperament characterized in infancy and early childhood by a tendency to withdraw from novel or unfamiliar stimuli. Children exhibiting this disposition, relative to children with other dispositions, are more socially reticent, less likely to initiate interaction with peers, and more likely to develop anxiety over time.…
