Hoffman L 《Journal of the American Psychoanalytic Association》2003,51(4):1219-1240
In this paper the author continues his study of conflicts over aggression in women, discussing the implications for contemporary theories of feminine psychology of observations of mothers in parent/child groups with their infants and toddlers. Many mothers experience conflicts over aggression (both in themselves and in their children) and become intolerant of their ambivalence toward their children. The author suggests that this observation provides an avenue that allows an integration of psychoanalytic ideas about maternity and childrearing with psychoanalytic understandings of women's conflicts about achievement in the social realm outside the home. In both roles, difficulties mastering conflicts with aggression may cause women to struggle profoundly, and to experience problems, in successfully negotiating their important life goals, whether the goals refer to their roles as effective mothers or their roles as effective individuals in the social sphere outside the home. Some women may demonstrate these difficulties in one sphere or the other, some in both, and others in neither. The author suggests on the one hand that we need to eliminate the concept of normality when considering the activities of women, and on the other hand that we need to normalize the omnipresence of ambivalence in the psychology of women. 相似文献

Longitudinal effects of lean production on employee outcomes and the mediating role of work characteristics 总被引:2,自引:0,他引:2
Parker SK 《The Journal of applied psychology》2003,88(4):620-634
The author discusses results from a 3 year quasi-experimental field study (N = 368), which suggest negative effects on employee outcomes after the implementation of 3 lean production practices: lean teams, assembly lines, and workflow formalization. Employees in all lean production groups were negatively affected, but those in assembly lines fared the worst, with reduced organizational commitment and role breadth self-efficacy and increased job depression. A nonequivalent control group had no negative changes in outcomes. Mediational analyses showed that the negative effects of lean production were at least partly attributable to declines in perceived work characteristics (job autonomy, skill utilization, and participation in decision making). The study also shows the longitudinal effects of these work characteristics on psychological outcomes. Implications for lean production, work design, and employee well-being are discussed. 相似文献

We investigated dorsal visual stream involvement in the retrieval of a variety of visual attributes of common objects, using
functional magnetic resonance imaging. Seven subjects made binary decisions about the shape, color, and size of named objects
during scanning. Bilateral parietal activity was significantly greater during retrieval of shape and size information than
during retrieval of color information. Consistent with a domain-specific distributed model of semantic organization, the finding
that dorsal stream activity is associated with size and shape retrieval, as compared with color retrieval, may indicate that
both size and shape information are learned partly through dorsally mediated processes, such as visually guided grasping.
These results demonstrate that both visual-processing streams (i.e., the ventral “what” pathway and the dorsal “where” pathway)
are involved in the storage and/or retrieval of knowledge of object appearance but that, just as in vision, these two pathways
may play different roles in conceptual processing. 相似文献

Parsing silhouettes: the short-cut rule. 总被引:2,自引:0,他引:2
Many researchers have proposed that, for the purpose of recognition, human vision parses shapes into component parts. Precisely how is not yet known. The minima rule for silhouettes (Hoffman & Richards, 1984) defines boundary points at which to parse but does not tell how to use these points to cut silhouettes and, therefore, does not tell what the parts are. In this paper, we propose the short-cut rule, which states that, other things being equal, human vision prefers to use the shortest possible cuts to parse silhouettes. We motivate this rule, and the well-known Petter's rule for modal completion, by the principle of transversality. We present five psychophysical experiments that test the short-cut rule, show that it successfully predicts part cuts that connect boundary points given by the minima rule, and show that it can also create new boundary points. 相似文献

Women's (N = 364) personal characteristics and gender role attitudes were examined in relation to their support for father involvement with children. The respondents completed measures of trust, attitudes toward women, hostility, self-esteem, and father involvement. Nontraditional gender role attitudes, positive ratings of their own interpersonal trust, and low hostility toward men were predictive of the respondents' support for father involvement. Participant demographics (including age, marital status, and number of children) were unrelated to their views of father involvement. Results indicate the importance of considering the characteristics and attitudes women bring to the co-parental relationship in the examination of factors influencing father involvement with children. Findings are discussed within the context of mothers' primary child-care and gatekeeping roles. 相似文献

We investigated the psychological impact of an organized visit to Polish concentration camps on Jewish-American adolescents. Eighty-seven adolescents who participated in a B'nai B'rith memorial visit to concentration camps in Poland completed measures of general psychological adjustment and posttraumatic stress disorder (PTSD) at four time-points: pretest, posttest, 6-month follow-up and 12-month follow-up. Measures included the SCL-90-R, the Mississippi Scale for PTSD, and the Impact of Events Scale (IES) for PTSD. On the SCL-90-R, changes in somatization, interpersonal sensitivity, obsessive-compulsive tendencies, depression, anxiety, and phobic anxiety were observed over time, with peak symptom scores at posttest and 6-month follow-up. Scores on the Mississippi Scale for PTSD and the IES Intrusion subscale also increased at 6-months. Predictors of PTSD symptoms on the Mississippi Scale included previous psychiatric treatment and SCL-90-R symptoms of paranoia, depression, and psychosis. Elevated psychotic symptoms on the SCL-90-R predicted PTSD symptoms on the IES. Jewish adolescents with preexisting symptoms of generalized distress or psychoticism appeared at increased risk for PTSD symptoms following exposure to Holocaust stimuli. This study contributes a prospective, multi-measure assessment of trauma reactions in adolescents. 相似文献

African American and White mother/adolescent pairs were examined for familial associations in body size and weight concerns. Mothers' and adolescents' estimates of adolescents' body mass index (BMI) were significantly correlated. Compared to boys, girls had greater body dissatisfaction, higher weight concerns, and perceived higher family/friend weight concerns. By race, White adolescents had more body dissatisfaction and greater concern about weight than African American adolescents. Four items explained 70.4% of the variance in adolescents' weight concern scores: adolescents' weight management practices, mothers' reports of adolescents' saying they were too fat, adolescents' perceptions of family/friends' weight concerns, and adolescents' body dissatisfaction. Our study suggests White girls are more concerned about their weight and perceive greater weight and dieting concerns among family/friends than African American girls. 相似文献

Depression is a serious problem among older adults and there is limited research on the most effective way to implement and evaluate the effects of expressive touch, either alone or in combination with verbalization, on levels of depression. A convenience sample of 24 institutionalized depressed older adult subjects (15 females and 9 males), ages 67 to 91 years was used for this study. An interrupted time series with multiple replications design was employed with four measurements: Geriatric Depression Scale (GDS), Life-Satisfaction-A-Scale, Rosenburg Self-Esteem Scale, and Locus of Control Scale. Four interventions were implemented: expressive touch only, verbalization only, a combination of expressive touch and verbalization, and a control (presence). Significant differences were found between pretest and posttest scores on the GDS for the expressive touch/verbal intervention. The most comfortable locations to implement the expressive touch and combination interventions were in the dining room or at the subject's bedside. The most comfortable areas of the subjects' bodies touched were the arms, hands, shoulders, and back. Results of this study support an important link between depression, self-esteem, locus of control, and life satisfaction and expressive touch either alone or when combined with talk. Touch as a mode of effective social support may have a therapeutic effect for depressed older adults. 相似文献
