This article suggests a comprehensive conceptual framework which identifies constructs for positive well-being as well as potential indicators and extant measures that fit with those constructs. In addition, the article reviews existing data sources for examples of positive measures that are found in the proposed framework as well as research studies that have been successful in measuring these indicators. The article then notes the data and measurement gaps that exist in comprehensively measuring the positive in children and youth. Finally, it identifies a number of conceptual and methodological issues that need consideration as efforts to define and measure positive indicators of well-being and well-becoming go forward. We argue that positive indicators represent good science, reflect and promote a positive vision of children, and establish positive goals for nations.  相似文献

Workers with disabilities are understudied, and workers with childhood onset of disability have been excluded from many of the studies on disability and work that do exist. This research compares the effects of childhood and adult onset of disability in a nationally representative sample of workers with disabilities. Educational disruptions due to disability status in childhood are negatively associated with life satisfaction and positively associated with perceived discrimination. Although age is associated with increased life satisfaction and decreased perceptions of discrimination for workers with adult disability onset, age is unrelated to these outcomes for workers with childhood disability onset. Receiving workplace accommodations is positively associated with satisfaction and negatively associated with discrimination for both groups, however, these relationships are stronger in magnitude for the childhood disability onset group. Organizational environments, both in education and in the workplace, play a critical role in the vocational well-being of workers with childhood disability onset.  相似文献

A central bar repeatedly presented in alternation with two flanking bars can lead to the disappearance of the central bar. Recently it has been suggested that this masking effect could be explained by object-mediated updating: the information from the central bar is integrated into the representation of the flankers, leading not only to the disappearance of the central bar as a separate object, but also to the perception of the flankers in apparent motion between their real position and the position of the central bar. This account suggests that the visibility of the central bar should depend on the same factors as those that influence the construction and maintenance of object representations. Therefore separation between central bar and flankers should not influence visibility as long as the time interval between them is adequate to make an interpretation of the scene in terms of one object moving from one location to the other possible location. We found that if the time interval between the central bar and the flankers is neither too short nor too long, the central bar becomes invisible even at large separations. These findings are inconsistent with traditional accounts of the cycling lateral masking displays in terms of local inhibitory mechanisms.  相似文献

What role do surface features (e.g., color) play in the establishment and maintenance of episodic representations of objects (object files)? Mitroff and Alvarez (2007) showed that stimuli that were linked by a continuous spatiotemporal history yielded object-specific preview benefits—a standard index of object files—whereas stimuli linked only by shared surface features did not. Here, it is shown that abruptly changing the features of an object that has been established on the basis of spatiotemporal history can disrupt object-specific preview benefits (Experiments 1 and 2). Moreover, under some conditions, feature match alone can give rise to the preview benefits (Experiment 3). These results indicate that surface features, as well as spatiotemporal factors, play an important role in establishing and maintaining episodic object representations.  相似文献

The tendency to hear a tone sequence as 2 or more streams (segregated) builds up, but a sudden change in properties can reset the percept to 1 stream (integrated). This effect has not hitherto been explored using an objective measure of streaming. Stimuli comprised a 2.0-s fixed-frequency inducer followed by a 0.6-s test sequence of alternating pure tones (3 low [L]-high [H] cycles). Listeners compared intervals for which the test sequence was either isochronous or the H tones were slightly delayed. Resetting of segregation should make identifying the anisochronous interval easier. The HL frequency separation was varied (0-12 semitones), and properties of the inducer and test sequence were set to the same or different values. Inducer properties manipulated were frequency, number of onsets (several short bursts vs. one continuous tone), tone:silence ratio (short vs. extended bursts), level, and lateralization. All differences between the inducer and the L tones reduced temporal discrimination thresholds toward those for the no-inducer case, including properties shown previously not to affect segregation greatly. Overall, it is concluded that abrupt changes in a sequence cause resetting and improve subsequent temporal discrimination.  相似文献

In three studies using both laboratory and field data, we show that the focal competitor’s strengths and weaknesses feature more prominently in predictions of the outcomes of future competitions than do the strengths and weaknesses of the opponents. People are more confident when their own side is strong, regardless of how strong the competition is. We show that this effect is driven by the fact that people have better information about their own side than the other side, in part because they preferentially seek out information about their own side. Implications for theories of decision making in competitive settings are discussed.  相似文献

Overweight in youth is increasing and physical inactivity has been implicated as a causal factor. An after-school care intervention, Youth Fit For Life, has been associated with significant improvements in physiological factors and frequency of moderate-to-vigorous physical activity voluntarily completed outside of structured settings. Correlates of the observed changes in physical activity amounts were, however, unknown. A multiple regression equation with simultaneous entry of sex, age, race, initial Body Mass Index, and initial frequency of voluntary physical activity as predictor variables for changes in physical activity was calculated on Euro-American and African-American participants ages 8 to 12 years (N=217). A statistically significant 16% of the variance in changes in frequency of voluntary physical activity over 12 wk. was accounted for, with only voluntary physical activity at baseline and age making significant, unique contributions. For participants either overweight or at risk for overweight (n=72), the changes in physical activity significantly correlated with changes in Body Mass Index. Implications of findings to maximize treatment effects on voluntary physical activity were suggested.  相似文献

It is argued that alongside the mentalistic and the behaviouristic forms, there is a third kind of gaze understanding. Gaze may be understood to be subjective in the sense that there can be diversity across self and other in terms of what is seen, without it being understood to be representational. This form of gaze understanding is more consistent with the evidence on toddlers' understanding of gaze and may well represent a developmentally intermediate form between the behaviouristic and mentalistic forms discussed in the target article.

Recent research calls into question the generally accepted conclusion that people believe themselves to be better than average. This paper reviews the new theories that have been proposed to explain the fact that better-than-average effects are isolated to common behaviors and abilities, and that people believe themselves to be below average with respect to rare behaviors and uncommon abilities. These new theories are then used to revisit prior findings of better-than-average effects. When viewed in light of recent work, the evidence suggests that prior findings overstated the degree to which people engage in self-enhancement by believing that they are better than others when in fact they are not. Prior studies have often confounded desirability with commonness and have used subjective measures of comparative judgment that capitalize on people’s tendency to conflate relative with absolute self-evaluation.  相似文献
