It seems self-evident that people prefer painful experiences to be in the past and pleasurable experiences to lie in the future. Indeed, it has been claimed that, for hedonic goods, this preference is absolute (Sullivan, 2018). Yet very little is known about the extent to which people demonstrate explicit preferences regarding the temporal location of hedonic experiences, about the developmental trajectory of such preferences, and about whether such preferences are impervious to differences in the quantity of envisaged past and future pain or pleasure. We find consistent evidence that, all else being equal, adults and children aged 7 and over prefer pleasure to lie in the future and pain in the past and believe that other people will, too. They also predict that other people will be happier when pleasure is in the future rather than the past but sadder when pain is in the future rather than the past. Younger children have the same temporal preferences as adults for their own painful experiences, but they prefer their pleasure to lie in the past and do not predict that others' levels of happiness or sadness vary dependent on whether experiences lie in the past or the future. However, from the age of 7, temporal preferences were typically abandoned at the earliest opportunity when the quantity of past pain or pleasure was greater than the quantity located in the future. Past–future preferences for hedonic goods emerge early developmentally but are surprisingly flexible.  相似文献

The purpose of this article is to broaden our understanding of colic and to explore the effects of infant colic both on the mother's stress level and on her anxiety about separation from her infant. A “colic” group of 20 mother-infant dyads was compared with a second, control “noncolic” group of equal size. Significant group differences in the amount of time the infants cried, fussed, and were in a quiet/awake state were found. Although no difference in maternal trait anxiety was found, mothers in the colic group reported higher levels of stress associated with their infants' crying behavior. This stress was inversely related to the amount of time the infants slept during a 24-hour period. Mothers in the colic group also expressed significantly greater anxiety about separating from their infants for short periods of time; but the lack of freedom was significantly less of a problem for them than it was for mothers in the noncolic group. We conclude that mothers of difficult infants are more anxious about being separated from their infants, but do not appear to feel “trapped” by their extra maternal duties.  相似文献

This essay presents an account of what it takes to live a philosophical way of life: practitioners must be committed to a worldview, structure their lives around it, and engage in truth-directed practices. Contra John Cooper, it does not require that one’s life be solely guided by reason. Religious or tradition-based ways of life count as truth directed as long as their practices are reasons responsive and would be truth directed if the claims made by their way of life are correct. The essay argues that these three conditions can be met by progressors as well as sages. Making progress in how one acts in the world, and improving one’s understanding and direction through being part of a community is living a philosophical way of life. The offered view acknowledges more ways to develop the art of living and enables a broader range of people to count as living philosophically.  相似文献

The question of whether understanding pretend play requires meta‐representational skill was examined among typically developing children and individuals with autism. Participants were presented with closely equated true and false pretence trials in which they had to judge a protagonist's pretend reading of a situation, which either matched or differed from their own. Results showed that individuals' theory of mind abilities determined their performance on false, but not true, pretence trials. These findings imply that meta‐representation is involved when an individual has to make sense of a pretend state of mind that differs from their own, but, crucially, they also show that pretend play can often be understood without meta‐representational competence.  相似文献

Midwestern personnel and management association members rated bogus job applications which had identical background qualifications but varied by sex of applicant, sex-role related attributes of applicant, and degree of fit of applicant credentials to job demands. The applicants were rated on their qualifications and likelihood of being considered for the position, expected performance, and expected success in the job. A significant triple interaction was found for the variable that measured the likelihood of the applicant being considered for the position (i.e., access to the position). Higher access ratings were given to the sex–stereotypical applicant when the applicant's credentials matched job demands. When the applicant's credentials did not fit the job demands, raters tended to favor non–stereotypical applicants. Practical and research implications are discussed.  相似文献

Structural equation modeling was used to evaluate components within the theories of reasoned action (TRA), planned behavior (TPB), and self-efficacy (SET) for understanding moderate and vigorous physical activity among 1,797 Black and White adolescent girls. Modest to strong support was provided for components of TPB and SET; weak support was provided for components of TRA. Perceived behavioral control was related to vigorous physical activity. Self-efficacy was related to moderate and vigorous physical activity, and it accounted for the effect of intention on physical activity. The observed relationships were similar between Black and White girls. Self-efficacy and perceived behavioral control are independent influences on physical activity among Black and White adolescent girls and warrant study as potential mediators in physical activity interventions.  相似文献
