Medical care at mass gatherings: considerations for physician involvement.

Although many authorities define a "mass gathering" as a group exceeding 1,000 persons, several times that number likely are to be present. The event for which the group will gather may be anything from a rock concert to an Olympic competition. Preparations for the event can be minor or major. This article reviews the issues that a physician should consider if he or she chooses to become involved in the delivery of medical care to such populations, as well as the evidence suggesting that a physician should be involved in most such gatherings. Emergency medical care at public gatherings is haphazard at best and dangerous at worst. There are surprisingly few data from which to plan the emergency medical needs for public events and no recognized standards or guidelines for providing emergency medical services at mass public gatherings.

Neuropsychological issues in the assessment of refugees and victims of mass violence.

Brain injury, stressor severity, depression, premorbid vulnerabilities, and PTSD are frequently intertwined in trauma populations. This interaction is further complicated when the neuropsychologist evaluates refugees from other cultures. In addition, the observed psychiatric symptoms reported in refugees and victims of mass violence may in fact not be the primary features of PTSD and depression but psychiatric symptoms secondary to the effects of traumatic brain injury. This paper reviews the occurrence of starvation, torture, beatings, imprisonment, and other head injury experiences in refugee and POW populations to alert treators to the presence of chronic and persistent neuropsychiatric morbidity, with implications for psychosocial adjustment. The concept of fixed neural loss may also interact with environmental and emotional stresses, and a model of neuropsychological abnormalities triggered by traumatic events and influenced by subsequent stress will also be considered. Neuropsychologists working with refugees play an important role in assessing the possibility of traumatic brain injury with tools that are relatively culture-fair.

Media guidelines on the reporting of suicide.

There is strong evidence for the existence of the Werther effect, or the phenomenon of an observer copying suicidal behavior he or she has seen modelled in the media. As a consequence, a number of countries have developed guidelines that promote responsible reporting of suicide. Using nine such guidelines as examples, this paper demonstrates that they tend to have similar content (emphasizing, for example, that suicide should not be glamorized or sensationalized and that explicit descriptions should be avoided, and stressing the importance of providing information about help services), but differ in the way in which they have been developed (e.g., the extent to which media professionals have been involved) and implemented (e.g., whether their "roll-out" has involved a considered dissemination strategy). The paper also reviews the evidence from evaluations of media guidelines, and concludes that it is too limited to determine whether the guidelines have had an impact on the behavior of media professionals or on completed and attempted suicide rates. It makes recommendations for further evaluative work, and suggests that the lessons from well-designed evaluations should be shared.

Crowd psychology in South African murder trials.

South African courts have recently accepted social psychological phenomena as extenuating factors in murder trials. In one important case, eight railway workers were convicted of murdering four strike breakers during an industrial dispute. The court accepted conformity, obedience, group polarization, deindividuation, bystander apathy, and other well-established psychological phenomena as extenuating factors for four of the eight defendants, but sentenced the others to death. In a second trial, death sentences of five defendants for the "necklace" killing of a young woman were reduced to 20 months imprisonment in the light of similar social psychological evidence. Practical and ethical issues arising from expert psychological testimony are discussed.

Ambient temperature and the occurrence of collective violence: the "long, hot summer" revisited.

Archival data pertaining to 102 instances of serious collective violence were examined in order to study the relationship between ambient temperature and the occurrence of such events. Results indicated that the frequency of collective violence and ambient temperature were curvilinearly related. Specifically, ambient temperature was directly associated with the frequency of collective violence through the mid-80s (degrees Fahrenheit). Beyond this point, however, further increments in temperature were associated with a decreasing incidence of such events. Additional findings indicated that ambient temperature increased significantly during the 7 days preceding the outbreak of collective violence, remained stable during its occurrence, but then decreased significantly in the 3 days following its termination. Possible implications of these findings, as well as their relationship to the results of previous laboratory studies, are discussed.

The baiting crowd in episodes of threatened suicide.

This study examines 21 cases in which crowds were present when a disturbed person threatened to jump off a building, bridge, or tower. Baiting or jeering occurred in 10 of the cases. Analysis of newspaper accounts of the episodes suggests several deindividuation factors that might contribute to the baiting phenomenon: membership in a large crowd, the cover of nighttime, and physical distance between crowd and victim (all factors associated with anonymity). The baiting phenomenon was also associated with warm temperatures and long duration of episode. These factors suggest leads for more systematic investigation.

Proposal of a four-dimensional model of social response.

Descriptive models of social response attempt to identify the conceptual dimensions necessary to define and distinguish various types of influence. Building on previous approaches, the authors propose a new response model and demonstrate that a minimum of 4 dimensions is necessary to adequately provide for such influence phenomena as conformity, minority influence, compliance, contagion, independence, and anticonformity in a single model. In addition, the proposed model suggests 5 potential types of response that have not been previously identified. These new types suggest directions for future research and theoretical development. Selected empirical evidence is reviewed in support of the validity and integrative power of the proposed model.

Bringing culture to basic psychological theory--beyond individualism and collectivism: comment on Oyserman et al. (2002).

D. Oyserman, H. M. Coon, and M. Kemmelmeir (2002) offered a comprehensive literature review on individualism and collectivism that forwards valuable suggestions for ways to enhance future research conducted within this framework. The author argues that although their criticisms of much contemporary social psychological research on individualism and collectivism are valid, even more fundamental problems need to be recognized as characterizing work within this tradition, such as the insufficiently subtle nature of the views held of culture, the limited attention given to meanings, and the downplaying of contextual variation. The author suggests adopting more nuanced and process-oriented conceptions of culture and more contextually grounded views of its impact on psychological functioning as a way of realizing the promise of cultural psychology to broaden and provide insight into basic psychological theory.

Do people have inflated views of their own ability.

An experiment tested a need-for-self-esteem notion that people inflate self-appraisals of ability, deny criticism, and overrespond to praise. Actors and bystanders rated actors' performances on a nonobjective task after hearing the performance praised or criticized or before hearing it evaluated. No evidence of self-enhancement was found; to the contrary, actors compared to bystanders rated themselves harshly, lowered their ratings after criticism equally, and showed relief after praise. A second experiment compared actor and bystander ratings of actors who expected evaluation of their performances or who expected no evaluation. Results suggested self-derogation by actors as a defense against possible loss of self-esteem.

Insect behaviour: migratory bands give crickets protection.

Mormon crickets and juvenile locusts form huge migratory bands--millions of individuals march in unison across the landscape and devastate vast agricultural areas, but little is known about why these bands form. Here we use radiotelemetry to show that band membership benefits these insects by greatly reducing the probability that they will become victims of predators. It is likely that migratory banding has evolved because it gives substantial protection to individuals within the group.
