We examined the influence of stance width (the distance between the feet) on postural sway and visually induced motion sickness. Stance width influences the magnitude of body sway, and changes in sway precede the subjective symptoms of motion sickness. Thus, manipulation of stance width may influence motion sickness incidence. Participants (healthy young adults) were exposed to complex, low-frequency oscillation of a moving room. Participants stood with their feet 5 cm, 17 cm, or 30 cm apart. During exposure to visual motion, the widest stance (30 cm) was associated with reduced incidence of motion sickness. For all stance widths, motion sickness was preceded by significant changes in motion of the head and torso. The results support the postural instability theory of motion sickness and suggest practical implications for the prevention of motion sickness. Adoption of wider stance may decrease the risk of motion sickness in operational situations. 相似文献

The authors examined the relation between early adolescents’ trust beliefs in peers and both their attributions for, and retaliatory aggression to, peer provocation. One hundred and eight-five early adolescents (102 male) from the United Kingdom (M age = 12 years, 2 months, SD = 3 months) completed the Children's Generalized Trust Beliefs in peer subscale (K. J. Rotenberg, C. Fox, et al., 2005) and reported the intentions of, and their retaliatory aggression to, hypothetical peer provocation. A curvilinear relation was found between trust beliefs in peers and retaliatory aggression but not for attributions of intention. Early adolescents with low and those with very high trust beliefs in peers reported greater retaliatory aggression than did early adolescents with the middle range of trust beliefs. The findings supported the conclusion that early adolescents who are high trusting, as well as those are very low trusting, are at risk for psychosocial maladjustment. Support was not obtained for a hostility attribution bias interpretation of those patterns. 相似文献

The authors examined age differences in perceived coping resources and satisfaction with life across 3 older-adult age groups (45-64, 65-74, and 75 years and older). The 98 participants represented healthy, socially active, community-residing adults. Group comparisons were made on 12 individual coping scales, and an overall coping resource effectiveness score was computed. No significant differences were found for 11 of the coping resources or for overall coping resource effectiveness. Similar consistencies in life satisfaction were found across the 3 age groups. The findings indicate that (a) for healthy adults, the oldest old cope at least as effectively as their younger counterparts, despite their likelihood of encountering increased levels of stress; and (b) psychologically, old age may be viewed as a time of resilience and fortitude. 相似文献

Young children's interpersonal trust consistency was examined as a predictor of future school adjustment. One hundred and ninety two (95 male and 97 female, Mage = 6 years 2 months, SDage = 6 months) children from school years 1 and 2 in the United Kingdom were tested twice over one year. Children completed measures of peer trust and school adjustment and teachers completed the Short-Form Teacher Rating Scale of School Adjustment. Longitudinal quadratic relationships emerged between consistency of children's peer trust beliefs and peer-reported trustworthiness and school adjustment and these varied according to social group, facet of trust, and indicator of school adjustment. The findings support the conclusion that interpersonal trust consistency, especially for secret-keeping, predicts aspects of young children's school adjustment. 相似文献

It is well known that theory in human cognitive ability or ‘intelligence’ is not well developed, especially with regard to sources of trait variation. Roots of theory have been sought in biology, and it is now widely accepted, on the basis of twin studies, and statistical analysis of variance, that at least half of the normal trait variation can be attributed to genetic variation, a correlation known as the trait ‘heritability’. Since the 1990s, methods in molecular biology have been adopted to go ‘beyond’ this mere statistical attribution to the identification of individual genes responsible for trait variation. More than a decade of intense effort, however, has failed to produce unambiguous, replicable findings; explanations for the ‘missing heritability’ are now being demanded; and calls for new perspectives on the roles of genes and environments in development and trait variation are being demanded. Here, I propose a dynamic systems perspective indicating how the processes in which heritability becomes missing are the very ones that provide the roots of new intelligence theory. 相似文献

Prior knowledge in the domain of mathematics can sometimes interfere with learning and performance in that domain. One of the best examples of this phenomenon is in students’ difficulties solving equations with operations on both sides of the equal sign. Elementary school children in the U.S. typically acquire incorrect, operational schemata rather than correct, relational schemata for interpreting equations. Researchers have argued that these operational schemata are never unlearned and can continue to affect performance for years to come, even after relational schemata are learned. In the present study, we investigated whether and how operational schemata negatively affect undergraduates’ performance on equations. We monitored the eye movements of 64 undergraduate students while they solved a set of equations that are typically used to assess children’s adherence to operational schemata (e.g., 3 + 4 + 5 = 3 + __). Participants did not perform at ceiling on these equations, particularly when under time pressure. Converging evidence from performance and eye movements showed that operational schemata are sometimes activated instead of relational schemata. Eye movement patterns reflective of the activation of relational schemata were specifically lacking when participants solved equations by adding up all the numbers or adding the numbers before the equal sign, but not when they used other types of incorrect strategies. These findings demonstrate that the negative effects of acquiring operational schemata extend far beyond elementary school. 相似文献

Homicide research at societal, subcultural, and interaction levels of analysis has not produced a comprehensive model for the killer‐victim transaction. But rules for organizing the experience of homicide can be generated from Simmel's definition of conflict as a “resolution of divergent dualisms” (1955:11). A model of homicide as a form of conflict resolution is demonstrated through interviews with a random sample of 35 adjudicated killers. Respondents’ definitions of homicide correspond to the conflict resolution model, with their verbal accounts, their socio‐psychological orientation to the victim at the point of the killing, their method of killing, and the general dynamics of the killer‐victim transaction, all varying as a resolution of a distinctive relationship, either between lovers, adversaries, or strangers. The situational definition casts homicide within the realm of normal behavior and at the same time delineates its distinctive features. 相似文献

This article brings together major new findings on homicide and suicide in order to contribute to an awareness of the similarities and differences between the two at both the structural and process levels of analysis, to make causal inferences, and to stimulate future research. Both homicide and suicide are processes of fixation on conflict resolution. The process of conflict resolution in turn is conditioned by structural disorganization. The process of fixation is conditioned by structural segregation, taking the particular form of estrangement, self‐reliance, and partial isolation. Intentional suicide, as distinct from intentional homicide, involves a negative fixation on self resulting primarily from the physical or psychological unavailability of a victim. The lack of a victim leaves the would‐be suicide feeling overwhelmed by the emotion that he or she fears. This process is conditioned by age and societal centralization, which together deny opportunities for homicide and detract from the kind of social support that might make life seem worthwhile. 相似文献

Abstract The present study was designed to identify risk factors for psychological morbidity in women attending a one-stop diagnostic clinic with suspected breast disease. A cohort of 158 women were recruited and were asked to complete scales measuring psychological morbidity and psychosocial factors in the period immediately before their appointment and to repeat the assessments of psychological morbidity on the day of the appointment. Relevant clinical and demographic data were also collated. Within the cohort 1.4% of respondents received a diagnosis of malignant disease. Psychological morbidity, both prior to and during the diagnostic appointment was strongly predicted by psychosocial factors (i.e., acceptance-resignation coping, personal self esteem and discrepancies in social support), accounting for 54% and 63% of the variance at pre-appointment and appointment day phases respectively. Other measured variables were found not to be correlated with and/or to account for a significant proportion of the variance in the measures of morbidity. These results suggest that these psychosocial variables should be targeted in interventions designed to reduce psychological morbidity in this patient group. 相似文献
