Impaired visual perception of hurtful actions in patients with chronic low back pain

Visually presented biological motion stimuli activate regions in the brain that are also related to musculo-skeletal pain. We therefore hypothesized that chronic pain impairs the perception of visually presented actions that involve body parts that hurt. In the first experiment, chronic back pain (CLBP) patients and healthy controls judged the lifted weight from point-light biological motion displays. An actor either lifted an invisible container (5, 10, or 15 kg) from the floor, or lifted and manipulated it from the right to the left. The latter involved twisting of the lower back and would be very painful for CLBP patients. All participants recognized the displayed actions, but CLBP patients were impaired in judging the difference in handled weights, especially for the trunk rotation. The second experiment involved discrimination between forward and backward walking. Here the patients were just as good as the controls, showing that the main result of the first experiment was indeed specific to the sensory aspects of the task, and not to general impairments or attentional deficits. The results thus indicate that the judgment of sensorimotor aspects of a visually displayed movement is specifically affected by chronic low back pain.     

Brain activity for visual judgment of lifted weight

It is well established that humans can recognize high-level aspects from point-light biological motion, such as gender and mood. If the task is to judge the manipulated weight we expected that sensorimotor regions should be recruited in the brain. Moreover, we have recently shown that chronic pain in a limb that is involved in the presented movement disturbs the weight judgment. We therefore hypothesized that some cortical regions usually activated during the processing of pain will also be activated while viewing point-light biological motion with the instruction to judge the manipulated weights. We investigated point-light biological motion of two types of movements performed with different weights in a blocked fMRI experiment in healthy subjects. In line with our a priori hypothesis, we found strong activity in the regions known as the neuromatrix of pain, such as the anterior cingulate (ACC), insula, as well as primary and secondary somatosensory regions. We also found activation in the occipital and temporal regions that are typical for biological motion, as well as regions in the cerebellum and prefrontal cortex. The activation of the somatosensory regions probably serves the judgment of the biological motion stimuli. Activation of the anterior cingulate and the insula might be explained by their role in the integration of behaviorally relevant information. Alternatively, these structures are known to be involved in the processing of nociceptive information and pain. So it seems possible that the interference between judgment of weights and perception of pain in chronic pain patients occurs in the somatosensory areas, anterior cingulate and/or insula. This finding provides important information as to the underlying mechanisms used for the weight judgment task, but also why chronic pain interferes with this task.     

A Triadic-behavioral approach to encopresis

Abstract

This paper describes the training and supervisory components of a doctoral level, pre-internship clinical experience, designed to teach Ph.D. candidates a contextual or systemic approach to therapy. The training occurred in a university-based departmental clinic which balanced the three interdependent areas of training, service and research. The therapeutic orientation was a problem-focused, goal-oriented, directive therapy candidates a contextual or systemic approach to therapy. The training designed to view and treat individuals in their social contexts. From this perspective, students were able to gain experience with individuals, couples and families. The paper discusses the function and components of the weekly supervision seminar and describes the integrative and sequential use of several innovative supervisory methods such as live supervision, peer consultation and videotape playback supervision.     

Normal crises: Stage theory and family therapy

Abstract

The theme of the Twenty-Third Georgetown University Symposium on Family Theory and Family Psychotherapy, held November 8 and 9,1986, in Washington, DC, was Toward a Science of Human Behavior. The program included famed sociobiologist Edward O. Wilson as the Distinguished Guest Lecturer; a special panel discussion about what is involved in moving toward a science of human behavior; a presentation by Murray Bowen, Director of the Georgetown University Family Center; a presentation by Walter Toman, who is well-known for his research on sibling position; and 10 other presentations related to various aspects of family systems theory and therapy.     

Empathy,Awareness of Others,and Action: How Feeling Empathy for One-Among-Others Motivates Helping the Others

Feeling empathy for a member of the group may result in either favoring this individual at the expense of the group or helping the entire group. We explain these intriguing findings by proposing that the combined influence of feeling empathy for one individual and awareness of others enhances willingness to help both the individual and the others (taken as individuals). The results of three experiments showed that inducing empathy for one individual promotes favoring him or her at the expense of the group, whereas inducing empathy for one-among-others leads to helping these others individually, instead of as a group. Furthermore, the awareness of others mediated the proposed one-among-others effect.     

Emotional speech processing: Disentangling the effects of prosody and semantic cues

To inform how emotions in speech are implicitly processed and registered in memory, we compared how emotional prosody, emotional semantics, and both cues in tandem prime decisions about conjoined emotional faces. Fifty-two participants rendered facial affect decisions (Pell, 2005a), indicating whether a target face represented an emotion (happiness or sadness) or not (a facial grimace), after passively listening to happy, sad, or neutral prime utterances. Emotional information from primes was conveyed by: (1) prosody only; (2) semantic cues only; or (3) combined prosody and semantic cues. Results indicated that prosody, semantics, and combined prosody–semantic cues facilitate emotional decisions about target faces in an emotion-congruent manner. However, the magnitude of priming did not vary across tasks. Our findings highlight that emotional meanings of prosody and semantic cues are systematically registered during speech processing, but with similar effects on associative knowledge about emotions, which is presumably shared by prosody, semantics, and faces.     

Examining Compulsive Sexual Behavior and Psychopathology Among a Sample of Postdeployment U.S. Male and Female Military Veterans

Compulsive sexual behavior (CSB) is defined as difficulties in controlling inappropriate or excessive sexual fantasies, urges, or behaviors that cause subjective distress or impairment in important areas of daily functioning. Using data from a baseline telephone interview, we examined the prevalence of CSB in a convenience sample of 820 postdeployed U.S. military male and female veterans and investigated correlates of CSB with sociodemographics and other mental health and sexual history characteristics. More men (13.8%) than women (4.3%) endorsed CSB-related symptoms. Given the limited sample size of women reporting CSB, correlational analyses were conducted only with men. After adjusting for significant sociodemographics, results indicated that gambling, suicidality, and sexually transmitted infections were significantly associated with male CSB. Current results suggest that CSB may be prevalent among U.S. military veterans post deployment and associated with significant negative health indices in men. CSB warrants attention regarding screening and intervention.     

Commentary on Malevolent Creativity

In Malevolent creativity: A functional model of creativity in terrorism and crime, Cropley, Kaufman, and Cropley (this issue) insightfully highlight two important aspects of the creative process. First, although it may not be popular nor initially obvious to discuss negatively applied, malevolent creativity, or terrorism/crime as potentially creative acts, it is certainly to our detriment not to if we truly seek to understand the full-spectrum under which the creative process operates. The second issue examined is the process by which a creative product's novelty declines with the passing of time. Each are briefly discussed.     

Post-LDAC Reflections of ROTC Cadets: Relationship to Leadership and Performance

In the United States Reserve Officer Training Program, cadets attend a month-long camp, where they are evaluated on leadership ability. The purpose of this study was to assess the experiences of cadets upon their return. Through semistructured interviews, with 25 cadets, 3 distinct higher order themes emerged: (a) perceived difficulty of the Leadership Development and Assessment Course, (b) psychological skills required for success, and (c) social climate experienced. Furthermore, upon completion of general inductive analysis, cadets’ responses were compared to their leadership score, thereby highlighting how salient aspects of leadership manifest themselves through cadets’ behaviors and performances.
