Adult attachment dimensions and recollections of childhood family context: associations with dispositional optimism and pessimism

The present study tested the theoretically inferred but not yet empirically tested association between dispositional optimism–pessimism and attachment security among 423 Finnish women and men. A second‐order latent variable representing a generalized representation of attachment insecurity in close relationships that included two latent constructs, the one representing romantic adult attachment dimensions and the other representing recollections of attachment‐related childhood family relationship, was associated with greater pessimism; the adult attachment dimension of high anxiety had unique and additional explanatory power, not accounted for by the generalized representation of attachment‐related insecurity. The model explained 48% of the variance in pessimism. The results clearly emphasize that additional studies are needed to clarify the role of interpersonal processes in dispositional optimism–pessimism. Copyright © 2004 John Wiley & Sons, Ltd.     

Trauma,War, and Spiritual Transformation: A Mythological Perspective

The statistics are staggering: Approximately 22 veterans commit suicide every day. A previous study done just a few short years ago put the numbers at 38 a day. Why? It is in the pursuit of an answer that this article came to be written, and a mythological lens seemed to bring the most understanding and depth to the possible answer. Out of the four functions of myths, it is the metaphysical one that helps us the most with understanding the causes and conditions of PTSD and the most profound reasons for suicide. With the help of philosophers such as Schopenhauer and Kant, we pierce the veil of the temporal forms of sensibility and experience the oneness of all life, as the soldier experiences it in the moment of life and death, the moment of killing. With the help of Martin Buber, we observe these veterans coming to a metaphysical understanding of a spiritual nature that they cannot undo. This truth is both the root of their suffering and the key to their healing.     

Achievement goal theory and disordered eating: Relationships of disordered eating with goal orientations and motivational climate in female gymnasts and dancers

ObjectivesTo examine the relationships between disordered eating in female gymnasts and dancers and their perspective towards achievement in sport and dance, respectively. With an emphasis on outperforming others (ego involvement), more disordered eating was expected than when personal progress (task involvement) was emphasized.MethodsNinety-four aesthetic performers from gymnastics (n = 59) and dance (n = 35) completed questionnaires measuring ego and task involvement (individual orientation and motivational climate), dieting, self-esteem, perfectionism and weight-related peer and coach pressure.ResultsPartial correlations indicated that a stronger ego orientation was related to more dieting, greater perfectionism, more weight-related peer pressure, and lower self-esteem. Similar relationships were found for performance climate. Mastery climate on the other hand was negatively related to dieting, and coach and peer pressure, suggesting that when performers perceived the motivational climate as mastery, less frequent dieting was reported and less weight-related coach and peer pressure was perceived. No relationships were found between task orientation and disordered eating. Most importantly, regression analysis showed that after controlling for BMI, both ego orientation and mastery climate made a unique significant contribution to explaining dieting variance.ConclusionsGoal achievement theory is an important framework for explaining disordered eating in female aesthetic performers. Both ego orientation and mastery climate play a role in dieting of gymnasts and dancers. Aesthetic performers who are strongly ego-oriented tend to display more disordered eating correlates. Furthermore, it seems that to protect against disordered eating, coaches and teachers should create a mastery climate and target self-improvement and self-referenced comparisons over interpersonal competitiveness.     

Interpersonal relations as a source of risk of mobbing in the local police

Social relations in the workplace are one of the main sources of risk for the onset of mobbing. In this work, we analyzed, through the perceived social climate, the influence of interpersonal relations on the characterization of the processes of mobbing, in a sample of local police (N = 235). In particular, the policemen and women's opinions of the quality of the personal relations among the group members and the treatment they receive from the command posts were assessed. The results of the study show that the development of guidelines of social interaction based on discrimination and abuse of authority are predicting variables of mobbing in this group.     

Effects of social stress on tumor development in dominant male mice with diverse behavioral activity profiles

We examined the influence of individual psychological profile and social behavior on tumor development in dominant male mice. Male OF1 mice were subjected to an open field test (OFT) to observe their motor activity and latency. Subsequently, the animals were divided into three groups: Stress-Non-Inoculated (SNI), Stress-Inoculated (SI) and Control-Inoculated (CI). The SI and CI groups were inoculated with tumor cells and the SNI group with vehicle. SNI and SI were exposed to social stress with an anosmic intruder six (T1) and twenty one (T2) days after inoculation and their behavior was analyzed. After T2, subjects were put down and the pulmonary metastatic foci counted. SI developed greater pulmonary metastasis than CI, indicating an effect of stress despite the animal's dominant status. Active animals developed less pulmonary metastasis than their passive counterparts. No differences were found in social behavior at T1. Differences were found, however, in some behavioral categories at T2 between SI and SNI, and between active and passive animals. These differences indicate an effect of tumor development on social behavior that is more evident in passive subjects.     

Reinforcement of wheel running in BALB/c mice: role of motor activity and endogenous opioids

The authors investigated the effect of the opioid antagonist naloxone on wheel-running behavior in Balb/c mice. Naloxone delayed the acquisition of wheel-running behavior, but did not reduce the expression of this behavior once acquired. Delayed acquisition was not likely a result of reduced locomotor activity, as naloxone-treated mice did not exhibit reduced wheel running after the behavior was acquired, and they performed normally on the rotarod test. However, naloxone-blocked conditioned place preference for a novel compartment paired previously with wheel running, suggesting that naloxone may delay wheel-running acquisition by blocking the rewarding or reinforcing effects of the behavior. These results suggest that the endogenous opioid system mediates the initial reinforcing effects of wheel running that are important in acquisition of the behavior.     

Brain c-Fos immunocytochemistry and cytochrome oxidase histochemistry after a fear conditioning task

The involvement of the basolateral and the medial amygdala in fear conditioning was evaluated using different markers of neuronal activation. The method described here is a combination of cytochrome oxidase (CO) histochemistry and c-Fos immunocytochemistry on fresh frozen brain sections. Freezing behavior was used as an index of auditory and contextual fear conditioning. As expected, freezing scores were significantly higher in rats exposed to tone-shock pairings in a distinctive environment (conditioned; COND), as compared to rats that did not receive any shocks (UNCD). CO labeling was increased in the basolateral and medial amygdala of the COND group. Conversely, c-Fos expression in the basolateral and medial amygdala was lower in the COND group as compared to the UNCD group. Furthermore, c-Fos expression was particularly high in the medial amygdala of the UNCD group. The data provided by both techniques indicate that these amygdalar nuclei could play different roles on auditory and contextual fear conditioning.     

The biochemical bases of the placebo effect

A great variety of medical conditions are subject to the placebo effect. Although there is mounting evidence to suggest that the placebo effect is related to the expectation of clinical benefit, little is still known about the biochemical bases underlying placebo responses. Positron emission tomography studies have recently shown that the placebo effect in Parkinson’s disease, pain, and depression is related to the activation of the limbic circuitry. The observation that placebo administration induces the release of dopamine in the ventral striatum of patients with Parkinson’s disease suggests a link between the placebo effect and reward mechanisms. In addition to Parkinson’s disease, the placebo-reward model may also apply to other disorders. However, the relative contribution of the different neurotransmitters and neuropeptides that are known to be involved in modulating the activity of the limbic system may be disease-specific. Thus, while the placebo-induced clinical benefit observed in Parkinson’s disease would mostly reflect the release of dopamine in the dorsal striatum, the activation of opioid and serotonin pathways could be particularly implicated in mediating placebo responses encountered in pain and depression, respectively. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.     

Visual search strategies of experienced and nonexperienced swimming coaches

The aim of this study consists of the application of an experimental protocol that allows information to be obtained about the visual search strategies elaborated by swimming coaches. 16 swimming coaches participated. The Experienced group (n=8) had 16.1 yr. (SD=8.2) of coaching experience and at least five years of experience in underwater vision. The Nonexperienced group in underwater vision (n= 8) had 4.2 yr. (SD= 4.0) of coaching experience. Participants were tested in a laboratory environment using a video-projected sample of the crawl stroke of an elite swimmer. This work discusses the main areas of the swimmer's body used by coaches to identify and analyse errors in technique from overhead and underwater perspectives. In front-underwater videos, body roll and mid-water were the locations of the display with higher percentages of fixation time. In the side-underwater slow videos, the upper body was the location with higher percentages of visual fixation time and was used to detect the low elbow fault. Side-overhead takes were not the best perspectives to pick up information directly about performance of the arms; coaches attended to the head as a reference for their visual search. The observation and technical analysis of the hands and arms were facilitated by an underwater perspective. Visual fixation on the elbow served as a reference to identify errors in the upper body. The side-underwater perspective may be an adequate way to identify correct knee angles in leg kicking and the alignment of a swimmer's body and leg actions.     

Contextual interference in learning precision skills

This research studied the effect of different organisations of practice (blocked and random) on the learning of three different types of throwing. 35 male students practiced three precise throws for 3 wk. Initially the subjects were separated into two groups who trained under different conditions of practice (blocked and random). All subjects improved significantly from initial performance, with both blocked practice and random practice. At the end of acquisition no differences were found between the groups. No significant differences were found on retention tests carried out 48 hr., 4 wk., and 8 wk. after the training period.
