Effects of a 6-week aerobic dance intervention on body image and physical self-perceptions in adolescent girls

Research examining the impact of physical activity on body image dissatisfaction and physical self-perceptions has been both limited and equivocal. The current research investigated the effects of 6-week aerobic dance on these variables with 50 British schoolgirls aged 13–14 years. A cross-over design was used with two equivalent groups taught normal physical education and aerobic dance in a different order. The Body Attitude Questionnaire (BAQ) and Children and Youth Physical Self-Perception Profile (CY-PSPP) were administered as pre, mid and post-test to each participant in each group before the first intervention, at the change over and after 12 weeks. The results of this study revealed that participation in 6 weeks of aerobic dance significantly reduced body image dissatisfaction (Attractiveness, Feeling Fat, Salience and Strength and Fitness) and enhanced physical self-perceptions (Body Attractiveness and Physical Self-Worth), although these improvements were not sustained. The implications and future research directions are discussed.     

Body image across the adult life span: stability and change

By far, the majority of studies investigating body image in adults have drawn samples from college populations within a very narrow age range. The purpose of the present paper is to review empirical research on the body image of adults older than the typical college student. There are marked changes in appearance across the adult life span, especially for women, which lead to the expectation of concomitant changes in body image. In fact, the review found that body dissatisfaction was remarkably stable across the adult life span for women, at least until they are quite elderly. In contrast, the importance of body shape, weight and appearance decreased as women aged, underscoring an important distinction between evaluation and importance of the body. However, there are many large gaps and limitations in the current literature that will need to be addressed before a more complete understanding of the development of body image across the adult life span is achieved.

A passion of the soul: an introduction to pain for consciousness researchers

Pain is an important focus for consciousness research because it is an avenue for exploring somatic awareness, emotion, and the genesis of subjectivity. In principle, pain is awareness of tissue trauma, but pain can occur in the absence of identifiable injury, and sometimes substantive tissue injury produces no pain. The purpose of this paper is to help bridge pain research and consciousness studies. It reviews the basic sensory neurophysiology associated with tissue injury, including transduction, transmission, modulation, and central representation. In addition, it highlights the central mechanisms for the emotional aspects of pain, demonstrating the physiological link between tissue trauma and mechanisms of emotional arousal. Finally, we discuss several current issues in the field of pain research that bear on central issues in consciousness studies, such as sickness and sense of self.     

The Face of Truth

I attempt to explain Plato's choice of dialogue through an analysis of what he regarded as the conditions of knowledge acquisition. I see the main contribution of the paper in exposing the way in which time and pain are, for Plato, conditions of knowledge acquisition. Plato endorsed the "learning through suffering," or pathei mathos , convention, central to Greek drama, and did so not through theory but through the praxis some of the dialogues employ. This addition of experiential components to the more cognitively oriented definitions of knowledge that Socrates uses complicates what these works may say about human knowledge. I analyze these tensions and the bearing they may have on the question of Plato's choice of dialogue, that is, on his rhetoric in practice. The requirements for actual persuasion, as Plato specifies them in the Seventh Letter, , are only partially met by the fictional scenes of argumentation and knowledge conveying that Plato presents. However, such scenes permit transcending some of the limitations of written, systematic, nonpersonal discourse. The presentation of such interactions to a real reader through dialogue turns into a mode of writing that is closer to meeting the demands of actual communication of knowledge – at least knowledge regarding what Plato envisaged as being the highest sort of epistemic communication     

Predictors of Psychosocial and Cognitive Adaptation in Children with Sickle Cell Syndromes

Examined the role of socioecological factors (family functioning and socioeconomic variables) in predicting behavioral and cognitive adaptation in children with sickle cell syndromes (SCD). Participants included 74 African American children and adolescents with SCD and their primary caretakers. Outcomes included internalizing and externalizing behavior symptoms, as rated by caretakers, as well as intellectual abilities and academic achievement, as assessed by individually administered standardized instruments. Family functioning consisted of both caretaker adjustment and family environment (i.e., family adaptability and cohesion). Hierarchical multiple regression analyses revealed that caretaker psychological adjustment predicted externalizing behaviors, while family environment (i.e., adaptability and cohesion) predicted neither behavioral nor cognitive functioning. Socioeconomic variables alone predicted intellectual abilities and academic achievement and also contributed to the prediction of child behavioral adaptation. Results are discussed in terms of relevant sociocultural issues and implications for family-level prevention and intervention.     

Children's Coping with Recurrent Headache

We investigated the relationships among perceptions of control over pain, gender, and coping responses in 57 school-aged children receiving services at a specialized pediatric headache clinic. Perceptions of control and gender interacted to predict frequency of active and negative coping responses. A wide range of coping strategies was reported, but only minimal gender or perceived control differences were found in the frequency and helpfulness of individual coping strategies. Results are discussed within the context of recent stress and coping models within the pediatric chronic illness literature.     

Physostigmine''s Impact on Brief Shock-Induced Hypoalgesia Parallels Its Effect on Memory

Past research indicates that the anticholinergic drug scopolamine disrupts memory and environmentally induced hypoalgesia in rats. The present study examined the impact of the centrally active cholinesterase inhibitor physostigmine, which enhances memory and central cholinergic activity, on brief shock-induced hypoalgesia on the tail-flick test using Sprague–Dawley rats. It is reported that physostigmine (0.1 mg/kg) potentiates the magnitude of this hypoalgesia. Contrary to past research, our results showed that omission of baseline testing did not eliminate hypoalgesia or its potentiation by physostigmine. Similar to its effects on memory, physostigmine (0.04, 0.1, and 0.25 mg/kg) has a nonmonotonic impact on brief shock-induced hypoalgesia; low doses potentiated hypoalgesia (0.1 mg/kg), whereas a high dose (0.25 mg/kg) disrupted it. These results provide further evidence that the cholinergic system indirectly affects pain reactivity by modulating the memory of the aversive event.     

Developmental differences in motor task integration: A test of Pascual-Leone's Theory of Constructive Operators

This study assessed the ability of Pascual-Leone's Theory of Constructive Operators to predict the minimum age or maturational level at which integration of a motor task could be achieved. Children 5–12 years of age (n=114) performed a discrete motor task requiring a constrained circular movement to be integrated with an unconstrained linear movement to a target. The Theory of Constructive Operators and the principles of constructive cognition were used to generate a model of task performance. Based on the model and in accordance with the theory, it was predicted that 5- to 6-year-old subjects would lack the cognitive capacity (M-capacity) to efficiently integrate this task. An analysis of covariance for age was performed on task parameters reflecting integration (and highest M-demand) with movement speed as the covariate. Scheffé contrasts supported the prediction as 5- to 6-year-old subjects were inferior to each of the other age groups (p < .05). Furthermore, no significant differences were found to exist between any of the older age groups.     

Reliability and standardization in the assessment of self-reported headache pain

The efficacy of a treatment intervention for head pain is typically evaluated by self-reported data. Self-monitoring schedules used to collect these data vary extensively across studies. The present article reviews conceptual and methodological problems with these self-report inventories. In addition, the most promising procedure was implemented in a study designed to measure the reliability of self-reported headache pain levels. One-hundred twenty-four college students self-monitored headache pain over an 8-week period. Three objective procedures were used to detect inaccurate recording. Subjects were also asked, in a post-experimental questionnaire, to subjectively rate the degree to which they complied with the experimenters' instructions regarding the self-monitoring procedures. Forty percent of the subjects were found to be noncompliant based on the detection techniques. However, responses to the postexperimental questionnaire indicated this to be a conservative estimation of noncompliance. There was no consistent difference between the postexperimental questionnaire for the subjects detected and those not detected. Results are discussed with relation to the need for researchers to adopt a standard methodology for (1) measuring self-reported headache pain and (2) reporting reliability data.Portions of these data were presented at the meeting of the Association for Advancement of Behavior Therapy, Chicago, November 1978.
