Lifeguards' vigilance: effects of child-adult ratio and lifeguard positioning on scanning by lifeguards

Observers recorded visual scanning by four lifeguards at three indoor public swimming pools. Scanning increased as a positive function of the ratio of children to adult swimmers, i.e., scanning was greater when the ratio was high, suggesting that lifeguards became more concerned about the risks to children and the ability of nearby adult swimmers to monitor these children when the number of children significantly exceeded the number of adults. Absolute numbers of children, however, decreased number of scans, possibly because of greater number of incidents and rule violations requiring lifeguards' attention which competed with watching the pool. Lifeguards were more likely to scan a pool area when they were in elevated towers versus standing on the pool decks. Lifeguards' scanning declined later in the day, possibly due to fatigue or because of competing activities of pool maintenance.

Personal relationships,personal attributes,and stress resistance: Mothers' reactions to their child's illness

The contribution to emotional distress of mastery, intimacy, received social support, and discomfort in seeking support was examined over a year period among 107 Israeli mothers of well, acutely ill, or chronically ill children. The following was found: (a) Women initially high in mastery experienced less psychological distress and benefited more from social support than did women low in mastery. (b) The greater social support women generally received the lower their psychological distress. (c) Independent of the level of generally received support, women who experienced greater distress received greater social support at the time of crisis. (d) Intimacy with spouse was related to better stress resistance, but the opposite was found for intimacy with family. (e) Women who felt uncomfortable seeking support were more distressed at the time of initial crisis than women who were more comfortable seeking support and became less intimate with significant others.     

Individual difference in anticipatory physiological responses to signaled stress: role of locus of control and autonomic balance.

Anticipatory cardiac activity to a signaled stressful event was hypothesized to be related to individual differences in locus of control and to autonomic balance. Subjects experienced 5 trials of a 105-db burst of white noise that was signaled by a milder tone. Significant increases in electrodermal as well as heart-rate responses occurred after the stress tone. While anticipating stress, the 10 subjects designated as having high levels of coherence between heart-rate and respiratory activity (high parasympathetic balance) showed reduced heart-rate and respiratory activity (high parasympathetic balance) showed reduced heart-rate variability over the 10 subjects with low coherence. Locus of control was not related to anticipatory activity. Anticipatory cardiac activity is discussed in light of two current psychophysiological models of attention.     

Gender differences in stress reactions: Women filling the gaps

Abstract

Competing hypotheses explaining gender differences in depression were compared in a one-year longitudinal study of parents of ill children in Israel. Women were found to have more depressed mood than men when their children were ill or well, but both men and women responded with increased depression when their child was ill. Women were more likely than men to be with an ill child at the hospital, even if employed, suggesting role overload. Women did not report fewer personal or social resources than men, indicating that poverty of resources could not explain sex differences on depression. Nor did women use their resources less effectively than did men. Women were less depressed the greater their intimacy with their spouse and friends, but at all levels of intimacy were more depressed than men. Men, in contrast, isolated themselves from social support at the time of their child's illness and it was argued that men might be avoiding stress contagion. The importance of examining differential responding of men and women to stressors that have common meaning for both sexes was discussed.     

Loss of Financial Capacity in Alzheimer's Disease: The Role of Working Memory

Recent research has demonstrated that loss of financial capacity is a common consequence of Alzheimer's disease (AD). While progressive cognitive decline is a defining feature of AD, the relationship between such decline and loss of financial capacity in AD remains unclear. Working memory may be strongly associated with financial abilities, as many financial tasks require temporary storage and manipulation of numerical and other data. The present study examined the relationship between financial capacity and working memory in AD patients. Participants included 20 AD patients and 23 cognitively intact older controls. Working memory was conceptualized using Baddeley and colleagues' model, which posits that the three components of the working memory system are the visuospatial sketchpad, phonological loop, and central executive system. The present study examined only the latter two components of working memory. Each participant was administered the Financial Capacity Instrument (FCI), an instrument that directly assesses eight domains of financial activity, and the WAIS-III Working Memory subtests (Digit Span, Arithmetic, Letter–Number Sequencing). AD patients as a group performed significantly below controls on the FCI Total Score and on each of the eight FCI domains and working memory subtests. Within the AD group, measures of the central executive component of working memory (WAIS-III Digits Backward, Arithmetic, and Letter-Number Sequencing tests) showed strong correlations with the FCI domains of basic monetary skills, checkbook management, bank statement management, and bill payment and FCI total score, while a measure of the phonological loop component of working memory (WAIS-III Digits Forward) was not significantly correlated with any FCI domains or with the FCI total score. The results suggest that the multiple domains of financial capacity are primarily correlated with the central executive component of working memory.     

Collective Trauma From the Lab to the Real World: The Effects of the Holocaust on Contemporary Israeli Political Cognitions

This research tested whether chronic or contextually activated Holocaust exposure is associated with more extreme political attitudes among Israeli Jews. Study 1 (N = 57), and Study 2 (N = 61) found that Holocaust primes increased support for aggressive policies against a current adversary and decreased support for political compromise via an amplified sense of identification with Zionist ideology. These effects, however, were obtained only under an exclusive but not an inclusive framing of the Holocaust. Study 3 (N = 152) replicated these findings in a field study conducted around Holocaust Remembrance Day and showed that the link between Holocaust exposure, ideological identification, and militancy also occurs in real‐life settings. Study 4 (N = 867) demonstrated in a nationally representative survey that Holocaust survivors and their descendants exhibited amplified existential threat responses to contemporary political violence, which were associated with militancy and opposition to peaceful compromises. Together, these studies illustrate the Holocaustization of Israeli political cognitions 70 years later.
