The Effects of Procedures, Social Accounts, and Benefits Level on Victims' Layoff Reactions 总被引:1,自引:0,他引:1
Three hundred and fifty-three layoff victims responded to questions describing their reactions to layoffs. Victims also described management layoff practices. Two measures of procedural fairness in layoff practices (decision-making characteristics and social accounts) and one measure of layoff outcomes (benefits level) were included. Only decision-making characteristics predicted exemployee willingness to recruit for a former employer and desire for regulation of layoffs. These results provide further evidence of the importance of procedural justice in organizational decision-making. 相似文献

In a study designed to assess the relationship between smoking status and correct identification of cigarette brands, junior high school students from two schools viewed cigarette and automobile advertisements with brand and model identification deleted. Results showed that adolescents with higher ad recognition scores were more likely to smoke cigarettes. In addition, a relationship was found between age and correct identification of cigarette advertisements, with older students identifying more ads correctly than younger students. No significant effects emerged for identification of automobile advertisements except for sex, with boys identifying more advertisements than girls. Additional findings indicated that even “experimental” smokers, who smoked as little as once per year, recognized significantly more cigarette advertisements than nonsmokers. These and other results are discussed in terms of their implications for prevention and policy issues. It is argued that society's allowance of printed cigarette advertising overlooks adolescents' heightened vulnerability to the kinds of appeals used in cigarette advertisements. Present policy also overlooks adolescents' relative unresponsiveness to the health risk information required in cigarette advertisements. 相似文献

Many adults who have survived the death by suicide of one or both parents remain victims of unresolved grief responses far into adulthood. This is all too frequently true, despite years of psychotherapy and or/consultations with representatives of various religious persuasions. Adult survivors of childhood parental suicide require an intervention which bridges the psychotherapeutic issues of parental loss and the spiritual issues raised by a sucidal death. The use of creative rituals is just such a response. By linking psychodynamic and spiritual issues, while simultaneously providing a current experiential process, a creative mourning ritual blends the needs of the inner child for mastery of the parental loss and the adult needs for a spiritual/meaning response. Mastery and meaning can concomitantly evolve through the process of designing, and then enacting, a ritual of grief completion. This is particularly effective, since the ritual is designed by the survivor to meet that person's unique needs. This presentation is an example of just such a ritual and will also include a very brief outline for ritual design. This approach would be useful to anyone working with survivors as well as to survivors themselves. 相似文献

Somatic complaints in anxious children 总被引:6,自引:0,他引:6
Deborah C. Beidel Mary Anne G. Christ Patrician J. Long 《Journal of abnormal child psychology》1991,19(6):659-670
Although stomachaches and headaches are considered characteristic of children with anxiety disorders, there is converging evidence that a broader range of somatic symptoms may be associated with children's expressions of anxiety. The purpose of this study was to determine the prevalence of somatic complaints in anxious children. The results indicated that children with anxiety disorders endorsed the presence of many different somatic complaints, and that contrary to clinical intuition, stomaches and headaches were not among the most commonly reported symptoms. In addition, the anxious children endorsed significantly more somatic complaints when compared to normal controls. Furthermore, the symptom pattern reported by anxious children indicated the presence of both the somatic and cognitive components usually associated with panic attacks, although none of the children met diagnostic criteria for panic disorder. The results are discussed in terms of the contribution of somatic symptoms to the understanding of anxiety disorders in children. 相似文献

We investigated the effects of background anger, provocation, and methylphenidate on emotional, physiological, and behavioral responding in children with attentiondeficit hyperactivity disorder (ADHD) with and without concurrent aggression. Our study revealed that ADHD boys showed more emotional and physiological distress when exposed to an interaction in which an administrator chastised each boy's favorite counselor, compared to a friendly interaction between the two adults. The background anger manipulation did not affect the aggressive behavior of the boys against an opponent in an aggressive game. High-aggressive (HA) ADHD boys were more likely to respond to provocation with aggression than low-aggressive (LA) ADHD boys, but only LA boys showed increased physiological reactivity with increasing provocation. Methylphenidate resulted in increased heart rates under all conditions and did not interact with any of the other findings.This project was conducted while the first author had the support of National Institute of Alcohol Abuse and Alcoholism grant AA 06267.The authors wish to thank the staff members of the 1987 Summer Day Treatment Program who assisted in conducting this project. The authors also express their appreciation to Karen Guthrie for coordinating the medication assessment and to Hart Blanton for computer programming. 相似文献

Early lexical development in children with focal brain injury 总被引:4,自引:0,他引:4

Early lexical development in 27 children with focal brain injury was studied cross-sectionally and longitudinally. Data were obtained from children between 12 and 35 months of age who acquired their lesion prenatally or within the first 6 months of life. Results for the group as a whole provide clear evidence for delays in lexical comprehension and production, and for a larger number of comprehension/production dissociations than would be expected by chance. In addition, a significant number of children were observed having unusual difficulty mastering predication and/or using an atypically high proportion of closed class words (suggesting reliance on holistic/formulaic speech). Analyses by lesion type revealed no effect of lesion size. Analyses according to side of lesion revealed that children with right-hemisphere damage produced a higher proportion of closed class words, suggesting heavy reliance on well-practiced but under-analyzed speech formulae. Children with left-hemisphere damage were slightly better in comprehension than children with right-hemisphere damage. In addition, left posterior lesions were associated with greater delays in expressive language, and delays were more protracted in children with left posterior damage. No differential effects of left posterior damage were found for lexical comprehension. 相似文献

We investigated differences between mildly depressed subjects and normal controls in their memory for, and judgments of, another person. All subjects read a story (containing either predominately positive or predominately negative items) under instructions to form an impression of the story target. Subjects later made several judgments about the target and attempted to recall the story. For both the positive and the negative story, depressed subjects produced significantly more negative intrusions (i.e., recalled nonpresented negative items) than did the normal subjects, but they did not recall more negative items correctly than did the normal subjects. Depressed subjects also perceived themselves as more similar to the negative story target than did the normal controls and indicated greater liking for the negative story target than did the normal controls. 相似文献

Conclusion Both Schutz and Gurwitsch describe reality as having a manifold character: Schutz speaks of multiple realities and Gurwitsch of orders of existence. Both hold that one realm of reality has a privileged status compared to the others: common everyday experience. However, in spite of this apparent convergence in their views, a closer reading of their various works reveal the important difference in what they understand under common everyday experience.For Schutz, it is the world of social action, characterized by him as paramount reality because of the constitutive processes of the experiences of time, space, sociality and meaning involved in action. For Gurwitsch, the realm of common everyday experience represents the counterpart and the origin of the constructed realm of science: therein lies its status of paramount reality. But what it really refers to is not ordinary experience, as most of his statements suggest, but pre-predicative experience, wherefrom the categories of the natural sciences, namely space and time, originate. Gurwitsch speaks of this pre-predicative experience, which he also calls primordial experience, as being essentially perceptual experience. However, he limits perceptual experience to sensory perception, leaving out the symbolic, social and action-related components of perception and becomes thus inconsistent with his adherence to the dismissal of the constancy hypothesis in his field theory of consciousness. The dismissal of the constancy hypothesis implies the recognition of the appresentational structures involving symbols, action and Others as inherent components of every perception. Schutz disagrees with Gurwitsch's reduction of the life-world Erlebnisse to sensory perception and this issue becomes the core of their debate on the phenomenon of paramount reality. 相似文献

Attractiveness ratings of 50 children aged 12–38 months were investigated in relation to adult socializing agents' behavior toward the children in their homes and play groups and their attitudes toward the children. Attractiveness scores were derived from 43 judges' ratings of facial photographs of the children. The same children were observed in play groups with female care givers; 40 of them were also observed in their homes with their parents. Play-group care givers rated the children for likability, tractability, and peer relations. Parents rated their attitudes toward giving routine care to their child. Attractiveness scores were not correlated with any adult attitude measures. Girls' attractiveness scores were positively correlated with their attempts to communicate in home and play group, and with mothers', fathers', and care givers' instructional responses, but negatively correlated with passive behavior in the home and with mothers' positive reactions. Boys' attractiveness scores were negatively correlated with passive behavior in the play group; no other significant correlations were found in the data for boys. 相似文献

This study examined the relationships among five measures that assess various cognitive components of the child's acquisition of gender. At around 2 years of age, children were given a task assessing their ability to accurately label as a boy or a girl some head-and-shoulders pictures of boys and girls. At 4 years of age, these children were given tasks measuring (1) the degree to which they found gender a salient parameter of categorization, (2) the amount of gender-related knowledge they could display (SERLI-SRD), (3) the degree to which their preferences were gender-typed (SERLI-SRP) and (4) the accuracy of their memory for gender-typed information. There was no consistent pattern of relationship among the children's scores on these five tools for measuring gender acquisition. Our findings suggest that gender is a multidimensional construct in children's development, and thus these results challenge the undimensional manner in which gender is repeatedly addressed in developmental theory and research.This research was funded in part by a federal biomedical research grant (No. 2507RR07080) awarded to the first author from the Department of Psychology at the University of Oregon, and by Grant No. RO1HD175751 from the National Institute of Child Development awarded to the third author.We wish to thank Margo Lane, Rachel Robertson, Jacqui Oucalt, Laura Baker, Dale Roberts, and the teachers, parents, and assistants of the Child Research Laboratory at the University of Oregon in Eugene, Oregon, for their invaluable contribution to this research. 相似文献
