不同情感强度正性生活事件的情感和行为反应:多模型的检验和整合

3个实验探讨情感强度不同正性生活事件对个体情感和行为反应的影响。发现:(1)面对复合正性生活事件(1高正+1低正),个体会感觉比面对1个单独的高正性情感强度事件的正性感受更低,出现平均效应,2个正性生活事件不如1个好;进一步研究发现:(2)当复合正性生活事件为异类时,出现平均效应;当事件为同类时,出现累加效应;(3)当复合正性生活事件有明显的时间特点时,个体加工符合峰-终定律的解释。     

Events and the ontology of individuals: verbs as a source of individuating mass and count nouns

What does mass-count syntax contribute to the interpretation of noun phrases (NPs), and how much of NP meaning is contributed by lexical items alone? Many have argued that count syntax specifies reference to countable individuals (e.g., cats) while mass syntax specifies reference to unindividuated entities (e.g., water). We evaluated this claim using the quantity judgment method, and tested the interpretation of words used in mass and count syntax that described either protracted, "durative" events (e.g., mass: some dancing; count: a dance), or instantaneous, "punctual" events (e.g., mass: some jumping; count: a jump). For durative words, participants judged, for example, that six brief dances are more dances but less dancing than two long dances, thus showing a significant difference in their interpretation of the count and mass usages. However, for punctual words, participants judged, for example, that six small jumps are both more jumps and more jumping than two long jumps, resulting in no difference due to mass-count syntax. Further, when asked which dimensions are important for comparing quantities of durative and punctual events, participants ranked number as first in importance for durative and punctual words presented in count syntax, but also for punctual words presented in mass syntax. These results indicate that names for punctual events individuate when used in either mass or count syntax, and thus provide evidence against the idea that mass syntax forces an unindividuated construal. They also indicate that event punctuality as encoded by verbs is importantly linked to the individuation of NPs, and may access a common underlying ontology of individuals.     

Posttraumatic Stress Symptoms and Stressful Life Events Predict the Long-term Adjustment of Survivors of Childhood Cancer and Their Mothers

Objectives: To examine prospectively the impact of posttraumatic stress symptoms (PTSS) in response to childhood cancer and treatment on general adjustment while accounting for the role of other stressful life events and appraisal of life threat and treatment intensity. Methods: As part of a larger study assessing PTSS, 56 childhood cancer survivors, aged 8 to 18, and 65 mothers completed self-report measures of PTSS and appraisal of the intensity and life threat associated with cancer treatment at time 1 and self-report measures of stressful life events and general adjustment at time 2 (approximately 18 months after time 1). Results: For child survivors and their mothers, posttraumatic stress at time 1 significantly predicted general adjustment at time 2, over and above the significant contribution of lifetime stressful events. The life events variable did not function as a mediator in the association of PTSS and general adjustment. Conclusions: Trauma responses to childhood cancer and its treatment have implications for the long-term adaptation of children and their families. Early signs and symptoms of posttraumatic stress and stressful life experiences require early assessment and intervention.     

Life‐events and post‐traumatic stress in a sample of English adolescents

The aim of the present study was to investigate the lifetime prevalence of negative life‐events and their association with post‐traumatic stress in English adolescents. Of the 427 adolescents surveyed, 360 (84%) endorsed at least one negative event. Respondents were asked to complete the Impact of Event Scale (IES: Horowitz, Wilner and Alvarez, 1979) for each event that they endorsed. For boys, highest levels of post‐traumatic stress were found in those who had experience of a ‘family member with a drink or drugs problem’, followed by ‘parental separation or divorce’, ‘life threat to family member’, and ‘life‐threat to self ’. For girls, highest levels of post‐traumatic stress were found in those who had experienced ‘attack or physical assault to self ’, followed by ‘family member with drink or drugs problem’, ‘parental separation or divorce’, and ‘life threat to family member’. These data suggest that moderate levels of post‐traumatic stress are present in around one fifth of adolescents who have experienced one of these events and that community levels of post‐traumatic stress in adolescents may be higher than previously thought.

Beliefs about what types of mechanisms produce random sequences

Although many researchers use Wagenaar's framework for understanding the factors that people use to determine whether a process is random, the framework has never undergone empirical scrutiny. This paper uses Wagenaar's framework as a starting point and examines the three properties of his framework—independence of events, fixed alternatives, and equiprobability. We find strong evidence to suggest that independence of events is indeed used as a cue toward randomness. Equiprobability has an effect on randomness judgments. However, it appears to work only in a limited role. Fixedness of alternatives is a complex construct that consists of multiple sub‐concepts. We find that each of these sub‐concepts influences randomness judgments, but that they exert forces in different directions. Stability of outcome ratios increases randomness judgments, while knowledge of outcome ratios decreases randomness judgments. Future directions for development of a functional framework for understanding perceptions of randomness are suggested. Copyright © 2008 John Wiley & Sons, Ltd.     

Adults also have difficulty recalling one instance of a repeated event

Some forms of abuse, such as domestic violence, tend to occur repeatedly. Although memory for repeated events has received considerable empirical attention, most of this research has used a child sample. Experiments that have examined adult repeated‐event memory tend to use vastly different methodological paradigms to that used for children. To investigate whether the same pattern of findings emerge with young adults, we adapted the methodological paradigm used in child repeated‐event experiments. In this experiment, 41 undergraduate students experienced one, or multiple similar events. All participants were then interviewed about the same event. Participants who had experienced a single‐event were more likely to report correct details than those who had experienced a repeated event. Repeated‐event participants were more likely to report general details. These results have implications for the methodological paradigm which is used to examine adult memory for a recurring event.     

Social relationships,stressful life events,and self-reported physical health: Genetic and environmental influences

Abstract

This study investigates how the associations between self-reported health, stressful life events, and social relationships are mediated by genetic and environmental influences and how much of the variance in health is in common with variation in these psychosocial factors. The analyses are based on questionnaire data from 576 pairs of twins reared apart and twins reared together. The data revealed that for men environmental influences were solely important for variation in the psychosocial measures and were the primary mediators of the relationship with health. For women, on the other hand, a substantial portion of the variance in the psychosocial factors was due to genetic influences and these influences also contributed to the bulk of the correlations with health. The gender differences for the relationships and their mediation indicate that what should be regarded as a psychosocial factor of importance for health might differ between genders.     

Handbook of adult resilience,edited by John W. Reich,Alex J. Zautra,and John Stuart Hall

This study investigated differences in adolescents’ life satisfaction (LS), apprehension of personal and non-personal events, and the influence of recalled life events on LS. The affective temperament (AFT) classification was the framework for the research. Seventy male and 65 female adolescents participated. AFTs were developed through self-reported affect, generating four temperaments: self-actualizing, high affective, low affective, and self-destructive. LS was also self-reported. Apprehension for events was assessed through two tasks: (1) life event recollection and (2) interpretation and recognition of words in a short story. High and low affectives interpreted and remembered events as both self-actualizers and self-destructives. All AFTs, with the exception of self-destructives, showed positive biases. Only individuals with high positive affect were positively primed for non-personal events. Life events predicted self-destructives’ and low affectives’ LS. Self-actualizers showed higher LS, measured for a second time in a sub-sample, than self-destructives. The importance of the AFTs is discussed.
