Fear generalization, in which conditioned fear responses generalize or spread to related stimuli, is a defining feature of anxiety disorders. The behavioral consequences of maladaptive fear generalization are that aversive experiences with one stimulus or event may lead one to regard other cues or situations as potential threats that should be avoided, despite variations in physical form. Theor...

The present research examined the perceptual style and coping pattern characterizing individuals with functional gastrointestinal disorders. A matched case-control design was adopted to compare differences among the target group of individuals with functional gastrointestinal disorders (n = 40), a pain control group of individuals with rheumatism (n = 40), and the community control group of hea...

INTRODUCTION Persistent postural-perceptual dizziness is the dizziness that lasts for over three months with no clinical explanation for its persistence. The patient's motor response pattern presents changes and most patients manifest significant anxiety. OBJECTIVE To evaluate the clinical characteristics of patients with persistent postural and perceptual dizziness. METHODS statistical ana...

Differential diagnosis of apraxia of speech (AOS) is complicated by frequently co-occurring speech and language disorders. Auditory-perceptual measures may not adequately differentiate between disorders. This study adapted an acoustic analysis protocol developed for Parkinson’s disease (PD). Preliminary results are positive, showing differences between individuals with AOS, PD, and healthy cont...

The exact nature and mechanisms of psychological change within psychological disorders remain unknown. This review aims to use a psychological framework known as Perceptual Control Theory (Powers, 1973, 2005; Powers, Clark, & McFarland, 1960) to integrate the diverse literature within psychotherapy research. The core principles of Perceptual Control Theory are explained, and key domains of psyc...

The purpose of this study was to evaluate sensoryand perceptual-motor performance of children with learning and behavioral disorders enrolled in a learning laboratory to see if these children have specific sensoryand perceptual-motor delays. Participants were 66 children (44 boys and 22 girls; M of age = 7.61 years; SD of age = 1.75 years). Sensoryand perceptualmotor performance of these childr...

Impairments in metacognition, the ability to accurately report one's performance, are common in patients with psychiatric disorders, where a putative neuromodulatory dysregulation provides the rationale for pharmacological interventions. Previously, we have shown how unexpected arousal modulates metacognition (Allen et al., 2016). Here, we report a double-blind, placebo-controlled, study that e...
