Emotional perception was examined in stroke patients across 3 communication channels: facial, prosodic, and lexical. Hemispheric specialization for emotion was tested via right-hemisphere (RH) and valence hypotheses, and relationships among channels were determined. Participants were 11 right-brain-damaged (RBD), 10 left-brain-damaged (LBD), and 15(More)
The cognitive effects of subthalamic nucleus (STN) stimulation in Parkinson's disease (PD) have been examined. However, there are no reported studies that evaluate, by incorporating a disease control group, whether neuropsychological performance in surgical patients changes beyond the variability of the assessment measures. To examine this issue, 17 PD(More)
This review focuses on facial asymmetries during emotional expression. Facial asymmetry is defined as the expression intensity or muscular involvement on one side of the face ("hemiface") relative to the other side and has been used as a behavioral index of hemispheric specialization for facial emotional expression. This paper presents a history of the(More)

Neocortical contributions to emotional processing are discussed. First, parameters critical to the neuropsychological study of emotion are examined: interhemispheric (right, left) and intrahemispheric (anterior, posterior) factors, processing mode (expression, perception), and communication channel (facial, prosodic, lexical). Second, neuropsychological(More)
Deficits in the perception of facial emotion have been demonstrated in patients with right-sided brain damage (RBD) and schizophrenia (SZ). Furthermore, recent speculations have implicated right-hemisphere dysfunction in Type II schizophrenics, especially those with a preponderance of "negative symptoms" and flat affect. The performance of SZ, RBD, and(More)
This study used fMRI to examine the response of the amygdala in the evaluation and short-term recognition memory of unpleasant vs. neutral words in nine right-handed healthy adult women. To establish specificity of the amygdala response, we examined the fMRI BOLD signal in one control region (visual cortex). Alternating blocks of unpleasant and neutral(More)
A meta-analysis was conducted to examine the effects of the written emotional disclosure paradigm on health outcomes of people with physical or psychiatric disorders. After nine studies were meta-analyzed, it was determined that expressive writing significantly improved health (d = .19; p < .05). However, this positive relationship (r = .10) was not(More)
The verbal output of patients with Parkinson's disease (PD) was analyzed for semantic and phonemic clusters on tasks of verbal fluency. One task required cued retrieval by semantic category (i.e. animals), and one required non-cued retrieval by initial letter (e.g. words beginning with 'F'). Nondemented PD patients (N = 25) produced significantly fewer(More)
The purpose of the current study was to examine 49 extant experiments of facial asymmetry during emotional expression in normal adult males and females in regard to gender, valence, and measurement technique. When facial asymmetry was evaluated by trained judges or muscle quantification, facial expressions were left-sided, a finding implicating the right(More)
This article presents a review of the neural mechanisms underlying emotional processing deficits (EPDs) in individuals with unilateral brain damage. First, key theoretical issues pertaining to the neuropsychology of emotion are presented. These include parameters of emotional processing, the componential approach, emotional domains, and hypotheses regarding(More)
