Association of Fine Motor Loss and Allodynia in Fibromyalgia: An fNIRS Study

Recent studies showed that fine motor control dysfunction was observed in fibromyalgia (FM) syndrome as well as allodynia. However, brain signatures of this association still remain unclear. In this study, finger tapping task (FTT) and median nerve stimulation (MNS) were applied to both hands of 15 FM patients and healthy controls (HC) to understand this relationship. Hemodynamic activity was measured simultaneously using functional near-infrared spectroscopy (fNIRS). Experiments were analyzed separately by using 2x2 repeated measures ANOVA. Results for the FTT experiment revealed that HC showed higher activity than FM patients in bilateral superior parietal gyrus (SPG), left supramarginal gyrus (SMG) and right somatosensory cortex (SI). Furthermore, right-hand FTT resulted in higher activity than left-hand FTT in left SPG, left SI and right motor cortex (MI). In the MNS experiment, FM patients showed higher activity than HC in bilateral SPG, right SMG, right SI and right middle frontal gyrus (MFG). Negative correlation was observed in left SPG between FTT and MNS activities. Besides, MNS activity in left SPG was negatively correlated with left-hand pain threshold.This study revealed that left SPG might be an important indicator to associate fine motor loss and allodynia in FM.     

Stability of Medical Students' Attitudes Toward Aging and Death

A representative sample from a nonclinical population was drawn to compare bingers and nonbingers across weight categories. Subjects were 112 women drawn from a cross-section of undergraduate classes at a large state university. Four groups were formed: obese bingers, obese nonbingers, normal-weight bingers (bulimics), and normal-weight nonbingers. Bingers, regardless of weight category, suffered higher levels of depression and anxiety and lower levels of self-esteem than nonbingers, regardless of weight category. Obese nonbingers were indistinguishable on these variables from normal-weight nonbingers, with both groups of nonbingers experiencing less emotional distress. Results support the position that the obese population should be conceptualized and treated as a diverse group with different psychological characteristics and needs.     

A Grounded Approach to the Study of Complex Systems

The complex and dynamic nature of systems pose a particular challenge to researchers and require the use of a research methodology designed to deal with such systems. The properties of fit, relevance, understandability, generality, control, workability, generalizability, and modifiability make Glaserian grounded theory and grounded action particularly well suited for studying systems. These methods are innovative, systemic, and sophisticated enough to reveal the underlying complexities of systems and plan actions that address their complex, dynamic nature while remaining grounded in what is occurring within the systems as they change over time.

Adolescent Focused Psychotherapy for Adolescents with Anorexia Nervosa

The paper describes a manualized specific form on individually based developmentally oriented therapy for Anorexia Nervosa (AN) in adolescents. Adolescent focused psychotherapy for AN is derived from a self-psychology model and is designed to address key deficits in development associated with AN. Adolescents with AN are viewed as using food and weight to avoid negative affective states associated with adolescent developmental issues that they perceive as intolerable. To develop a more constructive coping style and improve self-efficacy, adolescent patients need to first learn to identify and define their emotions, and later, to tolerate emotions, particularly negative ones. In withdrawing from the environment and situations which provoke distress through self-starvation and preoccupations with food and weight, emotional and psychological development is arrested. Learning to identify and cope adaptively with emotions and developmental challenges presented by the environment form the key therapeutic targets of treatment. Specific therapeutic procedures, a case illustration and discussion of therapeutic rationale are also provided.     

Which route to recovery? Controlled retrieval and accessibility bias in retroactive interference

New learning often interferes with the production of older, previously learned responses. However, the original responses usually appear to spontaneously recover and regain their dominance after a delay. This article takes a new approach to questions of interference and recovery by examining performance on immediate and delayed tests using direct or indirect instructions. Direct instructions asked participants to deliberately retrieve the original responses, and indirect instructions allowed them to respond on a more automatic basis, using whatever response came to mind first. Results suggest that interference and recovery may have their largest effects via relatively automatic influences on memory, such as the accessibility of new versus original information. This finding adds a new perspective to classic theories of interference and recovery, and may also inform current understanding of performance in populations (e.g., older adults) that often rely predominantly on automatic memory processing.     

A Critical Review of the Clinical Effects of Therapeutic Irradiation Damage to the Brain: The Roots of Controversy

We critically examined the damaging affects of therapeutic irradiation by comparing results from cross-disciplinary studies of early- and late-delayed radiotherapy effects. Focus is attained by concentrating on clinical treatment issues (volume of brain, dose, timing of effects, age, modality types, and stereotactic treatment techniques), rather than on methodological means or problems, which is necessary to understand the mechanisms and characteristics of radiotherapy-induced behavioral dysfunction including cognition. We make observations and hypotheses about the actual risks from radiotherapy that could be informative in the treatment decision process, and which may lessen the concerns of some patients and their families about the risks they take when receiving radiation. Conditions that predispose to radiation injury are reviewed: (1) higher doses even to part of the brain versus lower doses to the whole brain, (2) combined treatment modalities, (3) malignancy itself, (4) radiation early during postnatal brain development, and (5) late-delayed effects (more than 3 years posttreatment). Current neurocognitive frameworks for understanding cognitive change over time in children and adults are summarized, along with the literature on effects of brain tumors and treatment on depression. No studies have as yet identified candidate brain regions that are more sensitive to radiotherapy. Two studies have provided early, preliminary evidence for a specific vulnerability of visual attention/memory to the early stage of late radiation damage. Furthermore, radiation effects appear severe only in a minority of patients. Risk is related to direct and indirect effects of cancer type, concurrent clinical factors, and premorbid risk factors.     

Distraction as a determinant of processing speed

Processing speed is often described as a fundamental resource determining individual (e.g., I.Q.) and group (e.g., developmental) differences in cognition. However, most tests that measure speed present many items on a single page. Because many groups with slowed responding are also distractible, we compared younger and older adults on high-distraction (i.e., standard) versus low-distraction versions of two classic speed tasks. Reducing distraction improved the performance of older adults but had little or no effect on younger adults, suggesting that the ability to limit attentional access to task-relevant information can affect performance on tests designed to measure processing speed.     

Rural Chinese children as consumers: consumption experience and information sourcing

• This study examines how often rural children in Mainland China interact with different types of retail shops, how they learn about new products and services, and their attitudes toward different sources of product information. A survey of 1008 rural children aged from 5 to 13 years, in four Chinese provinces, was conducted in March 2003. Results indicated that rural Chinese children have limited access to various types of retail shops. Rural children perceived personal sources more useful as well as more credible than commercial sources in obtaining information about new products and services. Older children found parents and grandparents less useful and less credible than younger children for new production information. However, older children did not find peers more useful and credible than younger children.

A meta-analysis of team-efficacy,potency, and performance: interdependence and level of analysis as moderators of observed relationships

Meta-analytic techniques were used to examine level of analysis and interdependence as moderators of observed relationships between task-specific team-efficacy, generalized potency, and performance. Sixty-seven empirical studies yielding 256 effect sizes were identified and meta-analyzed. Results demonstrated that relationships are moderated by level of analysis. Effect sizes were stronger at the team level (p = .39) than at the individual level (p = .20). At the team level, both team-efficacy and potency had positive relationships with performance (ps = .41 and .37, respectively). Interdependence significantly moderated the relationship between team-efficacy and performance, but not between potency and performance. The relationship between team-efficacy and performance was stronger when interdependence was high (p = .45) than when it was low (p = .34).
