Overconcern with weight and shape and body dissatisfaction have both emerged as significant predictors of disordered eating. However, it is unclear how these constructs relate to each other, and if each has different antecedents and consequences. This study aimed to identify prospective predictors of each construct and to determine their relative importance in predicting dietary restraint and binge eating. Eight- to 13-year-old boys and girls (N = 259) were assessed at baseline and one-year follow-up, using a range of measures that included the Child Eating Disorder Examination. Psychosocial variables predicted overconcern with weight and shape whilst objective weight predicted body dissatisfaction. Body dissatisfaction and weight and shape concern predicted restraint, and weight and shape concern and restraint predicted binge eating. Findings provide support for the theoretical differences between body dissatisfaction and overconcern with weight and shape, and highlight the importance of focusing on specific body image variables. 相似文献

How Should We Do Nanoethics? A Network Approach for Discerning Ethical Issues in Nanotechnology 总被引:1,自引:1,他引:0
Ibo van de Poel 《Nanoethics》2008,2(1):25-38
There is no agreement on how nanoethics should proceed. In this article I focus on approaches for discerning ethical issues
in nanotechnology, which is as of yet one of the most difficult and urging tasks for nanoethics. I discuss and criticize two
existing approaches for discerning ethical issues in nanotechnology and propose a network approach as alternative. I discuss
debates in nanoethics about the desirable role of ethics in nanotechnological development and about the newness of ethical
issues in nanotechnology. On basis of a critical analysis of both debates, I formulate a number of desiderata for a method
for discerning ethical issues in nanotechnology and argue that the network approach that my colleagues and I have developed
for ethical issues in research and development networks is also appropriate in nanotechnology.

QWL is conceptualized in terms of the interface between employee role identities and work resources. QWL programs serve to
enhance QOL by (1) providing appropriate work resources to meet the expectations of employee role identities, (2) reducing
role conflict in work and non-work life, (3) enhancing multiple role identities, (4) reducing role demands, (5) reducing stress
related to work and non-work role identities, and (6) increasing the value of the role identity. We describe a variety of
QWL programs related to work life (decentralized organization structures, teamwork, parallel structures, ethical corporate
mission and culture, the organization work schedule, etc.) and non-work life (work at home, flextime, compressed work week,
part-time work arrangements, job sharing, etc.) and show how they serve to enhance QOL using the language of work-life identity.
Doing so helps develop a research agenda based on the work-life identify model. 相似文献

Innis RE 《Integrative psychological & behavioral science》2008,42(1):20-26
I discuss the problem of using the emotional/cognitive duality as a satisfactory way of formulating the problem of linguistic
origins and of the distinctiveness of literary language. I address in particular Shanahan’s use of the work of Ernst Cassirer
and Susanne Langer. I point out that Cassirer offers us a multileveled model of language’s sense-functions which avoids false
oppositions and that Langer shows that literature does not belong to the discursive but to the presentational order of symbolism.
Such insights strengthen rather than weaken Shanahan’s main points about the ‘localization’ and nature of meaning.

Harmonic priming studies have provided evidence that musical expectations influence sung phoneme monitoring, with facilitated processing for phonemes sung on tonally related (expected) chords in comparison to less-related (less-expected) chords [Bigand, Tillmann, Poulin, D’Adamo, and Madurell (2001). The effect of harmonic context on phoneme monitoring in vocal music. Cognition, 81, B11–B20]. This tonal relatedness effect has suggested two interpretations: (a) processing of music and language interact at some level of processing; and (b) tonal functions of chords influence task performance via listeners’ attention. Our study investigated these hypotheses by exploring whether the effect of tonal relatedness extends to the processing of visually presented syllables (Experiments 1 and 2) and geometric forms (Experiments 3 and 4). For Experiments 1–4, visual target identification was faster when the musical background fulfilled listeners’ expectations (i.e., a related chord was played simultaneously). In Experiment 4, the addition of a baseline condition (i.e., without an established tonal center) further showed that the observed difference was due to a facilitation linked to the related chord and not to an inhibition or disruption caused by the less-related chord. This outcome suggests the influence of musical structures on attentional mechanisms and that these mechanisms are shared between auditory and visual modalities. The implications for research investigating neural correlates shared by music and language processing are discussed. 相似文献

According to the conjunction rule, the probability of A and B cannot exceed the probability of either single event. This rule reads and in terms of the logical operator wedge, interpreting A and B as an intersection of two events. As linguists have long argued, in natural language "and" can convey a wide range of relationships between conjuncts such as temporal order ("I went to the store and bought some whisky"), causal relationships ("Smile and the world smiles with you"), and can indicate a collection of sets rather than their intersection (as in "He invited friends and colleagues to the party"). When "and" is used in word problems researching the conjunction fallacy, the conjunction rule, which assumes the logical operator wedge, therefore cannot be mechanically invoked as a norm. Across several studies, we used different methods of probing people's understanding of and-conjunctions, and found evidence that many of those respondents who violated the conjunction rule in their probability or frequency judgments inferred a meaning of and that differs from the logical operator wedge. We argue that these findings have implications for whether judgments involving ambiguous and-conjunctions that violate the conjunction rule should be considered manifestations of fallacious reasoning or of reasonable pragmatic and semantic inferences. 相似文献

The level of racism in Australia against Aboriginal Australians is well documented. This has an extremely detrimental effect on the health and wellbeing of Aboriginal Australians. One part of the solution may be anti‐prejudice strategies, but to date few strategies that include a pre‐test and a post‐test assessment have been conducted in Australia. The present study describes the interventional qualities of a cultural psychology unit at an Australian university. Results indicated that after a 6‐week period, students reported a significant reduction in prejudice, acceptance of false beliefs about Aboriginal Australians, and the perception that Aboriginal Australians unfairly receive preferential or special treatment. The article concludes that cultural psychology units have the potential to be an effective way of developing acceptance of cross‐cultural differences. 相似文献

Newborns' face recognition over changes in viewpoint 总被引:2,自引:0,他引:2
The study investigated the origins of the ability to recognize faces despite rotations in depth. Four experiments are reported that tested, using the habituation technique, whether 1-to-3-day-old infants are able to recognize the invariant aspects of a face over changes in viewpoint. Newborns failed to recognize facial perceptual invariances between profile and full-face poses (Experiment 1), and profile and 3/4 poses (Experiment 3). Conversely, newborns recognized the identity of a face through full-face and 3/4 poses (Experiment 2). This result cannot be explained as a consequence of newborns' inability to discriminate between the full-face and 3/4 points of view (Experiment 4). Overall, evidence was provided that newborns are able to derive a representation of an unfamiliar face that is resilient to a certain degree of rotation in depth, from full-face to 3/4 and vice versa. 相似文献

Three studies addressed children's arithmetic. First, 50 3- to 5-year-olds judged physical demonstrations of addition, subtraction and inversion, with and without number words. Second, 20 3- to 4-year-olds made equivalence judgments of additions and subtractions. Third, 60 4- to 6-year-olds solved addition, subtraction and inversion problems that varied according to the inclusion of concrete referents and number words. The results indicate that number words play a different role in conceptual and procedural development. Children have strong addition and subtraction concepts before they can translate the physical effects of these operations into number words. However, using number words does not detract from their calculation procedures. Moreover, consistent with iterative relations between conceptual and procedural development, the results suggest that inversion acquisition depends on children's calculation procedures and that inversion understanding influences these procedures. 相似文献

The present research investigated the extent to which the stereotype that young Black men are threatening and dangerous has become so robust and ingrained in the collective American unconscious that Black men now capture attention, much like evolved threats such as spiders and snakes. Specifically, using a dot-probe detection paradigm, White participants revealed biased attention toward Black faces relative to White faces (Study 1). Because the faces were presented only briefly (30-ms), the bias is thought to reflect the early engagement of attention. The attentional bias was eliminated, however, when the faces displayed averted eye-gaze (Study 2). That is, when the threat communicated by the Black faces was attenuated by a relevant, competing socio-emotional cue—in this case, averted eye-gaze—they no longer captured perceivers’ attention. Broader implications for social cognition, as well as public policies that reify these prevailing perceptions of young Black men are discussed. 相似文献
