This study provides unique empirical evidence regarding a growing concern internationally: weight discrimination in the workplace. Using survey data from a national sample of 2838 American adults, it responds to Puhl and Brownell’s [Puhl, R., & Brownell, K. D. (2001). Bias, discrimination, and obesity. Obesity Research, 9, 788-805] call for additional research investigating the prevalence of discriminatory experience among overweight employees, and to their more specific call for research that takes sex and race into account when examining weight discrimination. The results indicate that women are over 16 times more likely than men to perceive employment related discrimination and identify weight as the basis for their discriminatory experience. In addition, overweight respondents were 12 times more likely than normal weight respondents to report weight-related employment discrimination, obese 37 times more likely, and severely obese more than 100 times more likely. The implications of the study’s findings for organizations, policy makers, overweight employees, and career counselors are discussed, and future research directions suggested. 相似文献

BACKGROUND: The influence of stress on neuropsychological functioning was assessed in socially phobic (SP), comorbid socially phobic/major depression (CM), and asymptomatic control subjects (AC) under baseline and stressor conditions. METHODS: Subjects were 33 clinically diagnosed undergraduates aged 18 to 41 years. Neuropsychological measures included the Trail Making Test, Wisconsin Card Sorting Test (WCST), Spatial Span, and Digit Span administered during a baseline condition and a psychosocial stress condition (videotaping). RESULTS: Spatial Span scores were reduced for SP during stress, improved for AC, and showed no change for CM. TMT B times showed an interaction effect, with completion time improving significantly less for SP than for AC and CM during stress. Analyses of the normative data for WCST total errors indicated that AC and CM improved significantly during stress, while SP performance declined during stress. CONCLUSIONS: The present findings suggest that comorbid depressed versus non-depressed SP subjects respond uniquely to stress in terms of their neuropsychological functioning and self-reported mood and experiences; generalized social phobia may be associated with spatial working memory disturbance during social stress. Therefore, situations involving potential social and personal evaluation (e.g., examinations or presentations) may have a significant impact on the neuropsychological functioning of SP individuals. 相似文献

In the type of intraverbal that consists of saying the opposite of a word, two intraverbals are related to one another because the response form of each intraverbal functions as part of a discriminative stimulus for the other (e.g., "cold" in response to "name the opposite of hot," and vice versa). Moreover, the contextual cue "Name the opposite of--" is the same in the two intraverbals. The purpose of the present research was to explore a procedure designed to promote emergence of intraverbals of this type. Two children with pervasive developmental disorder learned pairs of intraverbals. Thereafter, they were tested for emergence of intraverbals with reversed stimulus-response functions. Results indicate that, although the participants did not initially show emergence of intraverbals with reversed stimulus-response functions, repeated cycles of probing and teaching facilitated emergence of these relations. 相似文献

The present research examines the semantic priming effects of a centrally presented single prime word to which participants were instructed to either "attend and remember" or "ignore". The prime word was followed by a central probe target on which the participants made a lexical decision task. The main variables manipulated across experiments were prime duration (50 or 100 ms), the presence or absence of a mask following the prime, and the presence (or absence) and type of distractor stimulus (random set of consonants or pseudowords) on the probe display. There was a consistent interaction between the instructions and the semantic priming effects. Relative to the "attend and remember" instruction, an "ignore" instruction produced reduced positive priming from single primes presented for 100 ms, irrespective of the presence or absence of a prime mask, and regardless of whether the probe target was presented with or without distractors. Additionally, reliable negative priming was found from ignored primes presented for briefer durations (50 ms) and immediately followed by a mask. Methodological and theoretical implications of the present findings for the extant negative priming literature are discussed. 相似文献

This study investigated the predictors of posttraumatic stress disorder (PTSD) in children following a diagnosis of traumatic injury. Children (N=76) aged between 7 and 13 who were admitted to hospital following injury were assessed within a month of trauma for acute stress disorder (ASD), negative appraisals, as well as parental stress reactions. Children (N=62) were re-assessed 6-months later for PTSD and negative appraisals. The majority of the variance of chronic posttraumatic stress was accounted for by negative appraisals about future harm. This study supports cognitive models of PTSD, and suggests that younger children who exaggerate their vulnerability after trauma exposure are high risk for PTSD after trauma. 相似文献

Using Mandarin Chinese, a "tone language" in which the pitch contours of syllables differentiate words, the authors examined the acoustic modifications of infant-directed speech (IDS) at the syllable level to test 2 hypotheses: (a) the overall increase in pitch and intonation contour that occurs in IDS at the phrase level would not distort lexical pitch at the syllable level and (b) IDS provides exaggerates cues to lexical tones. Sixteen Mandarin-speaking mothers were recorded while addressing their infants and addressing an adult. The results indicate that IDS does not distort the acoustic cues that are essential to word meaning at the syllable level; evidence of exaggeration of the acoustic differences in IDS was observed, extending previous findings of phonetic exaggeration to the lexical level. 相似文献

Vocabulary growth was suggested to prompt the implementation of increasingly finer-grained lexical representations of spoken words in children (e.g., [Metsala, J. L., & Walley, A. C. (1998). Spoken vocabulary growth and the segmental restructuring of lexical representations: precursors to phonemic awareness and early reading ability. In J. L. Metsala & L. C. Ehri (Eds.), Word recognition in beginning literacy (pp. 89-120). Hillsdale, NJ: Erlbaum.]). Although literacy was not explicitly mentioned in this lexical restructuring hypothesis, the process of learning to read and spell might also have a significant impact on the specification of lexical representations (e.g., [Carroll, J. M., & Snowling, M. J. (2001). The effects of global similarity between stimuli on children’s judgments of rime and alliteration. Applied Psycholinguistics, 22, 327-342.]; [Goswami, U. (2000). Phonological representations, reading development and dyslexia: Towards a cross-linguistic theoretical framework. Dyslexia, 6, 133-151.]). This is what we checked in the present study. We manipulated word frequency and neighborhood density in a gating task (Experiment 1) and a word-identification-in-noise task (Experiment 2) presented to Portuguese literate and illiterate adults. Ex-illiterates were also tested in Experiment 2 in order to disentangle the effects of vocabulary size and literacy. There was an interaction between word frequency and neighborhood density, which was similar in the three groups. These did not differ even for the words that are supposed to undergo lexical restructuring the latest (low frequency words from sparse neighborhoods). Thus, segmental lexical representations seem to develop independently of literacy. While segmental restructuring is not affected by literacy, it constrains the development of phoneme awareness as shown by the fact that, in Experiment 3, neighborhood density modulated the phoneme deletion performance of both illiterates and ex-illiterates. 相似文献

Portrayals of schizophrenia in popular film contribute to misinformation about treatment of schizophrenia. Can film by used to educate? This study examined the effectiveness of viewing film portrayals of accurate vs. inaccurate information about schizophrenia in correcting misinformation. A video was constructed consisting of segments from popular movies and documentaries that contrasted inaccurate and accurate illustrations of schizophrenia. College students were randomly assigned to either the video presentation or traditional lecture on schizophrenia, and later tested on their knowledge of schizophrenia. Results showed knowledge improvement following both video and lecture, with video having a greater corrective effect for female students after viewing 3 of the 8 segments. These results are discussed with reference to sex-role socialization and empathetic identification. 相似文献

This study explores incremental processing in spoken word recognition in Russian 5- and 6-year-olds and adults using free-viewing eye-tracking. Participants viewed scenes containing pictures of four familiar objects and clicked on a target embedded in a spoken instruction. In the cohort condition, two object names shared identical three-phoneme onsets. In the noncohort condition, all object names had unique onsets. Coarse-grain analyses of eye movements indicated that adults produced looks to the competitor on significantly more cohort trials than on noncohort trials, whereas children surprisingly failed to demonstrate cohort competition due to widespread exploratory eye movements across conditions. Fine-grain analyses, in contrast, showed a similar time course of eye movements across children and adults, but with cohort competition lingering more than 1s longer in children. The dissociation between coarse-grain and fine-grain eye movements indicates a need to consider multiple behavioral measures in making developmental comparisons in language processing. 相似文献

This study demonstrates that experience and development interact to influence the "cross-race effect." In a multination study (n=245), Caucasian children and adults of European ancestry living in the United States, Norway, or South Africa, as well as biracial (Caucasian-African American) children and adults living in the United States, were tested for recognition of Asian, African, and Caucasian faces. Regardless of national or biracial background, 8- to 10-year-olds, 12- to 14-year-olds, and adults recognized own-race faces more accurately than other-race faces, and did so to a similar extent, whereas 5- to 7-year-olds recognized all face types equally well. This same developmental pattern emerged for biracial children and adults. Thus, early meaningful exposure did not substantially alter the developmental trajectory. During young childhood, developmental influences on face processing operate on a system sufficiently plastic to preclude, under certain conditions, the cross-race effect. 相似文献
