This study investigated the influence of changing socio-historical conditions on personal goals in young adulthood. It was
hypothesized that socio-historical changes related to individualization have resulted in shifts in goal pursuit. Participants
from three birth cohorts reconstructed their important goals when they were 20 years old. Members of the oldest cohort were
born between 1920 and 1925. Members of the middle cohort were born between 1945 and 1950. Members of the youngest cohort were
born between 1970 and 1975. Goal content, the degree to which goals were perceived as being shared by members of the same
cohort (social sharedness), perceived control over goal attainment, success in attainment, and life satisfaction at age 25
were measured in a retrospective study. Results show consistent shifts over time. Whereas members of older cohorts mentioned
goals related to classical developmental tasks, members of younger cohorts mentioned more individualistic, self-related goals
and goals related to education. The processes through which goal pursuit influenced life satisfaction also changed. Perceived
social sharedness of goals was a direct predictor of life satisfaction for the oldest cohort. For the younger cohorts, perceived
control over goal attainment influenced success which in turn influenced life satisfaction. These changes support the contention
that developmental tasks and processes are historically variant. 相似文献

Abstract: The nature of fantasy has been little discussed, despite its importance in the arts. Its significance is brought out here in relation to the long‐standing debate on the alleged paradox of fiction—that we respond emotionally to characters and events known to be unreal. Examination of the paradox shows it to be ill founded once the nature of fantasy is appreciated. Moreover, a detailed consideration of fantasy shows that it can itself provide a plausible account of our emotional reactions to creative literature, an account that, after a review of some possible objections, is then contrasted with the leading contemporary theories. 相似文献

The present longitudinal study extends the findings of earlier cross-sectional studies (Waterman, Schwartz, Green, Miller, & Philip, 2003) on the subjective experience of intrinsic motivation. University students generated lists of personally salient (identity-related) activities at the beginning of an academic semester and were asked to evaluate these activities at three points during the semester. Drawing on theories of intrinsic motivation, three subjective indices of intrinsic motivation (interest, flow experiences, and feelings of personal expressiveness) and three theoretically derived predictor variables (self-determination, the balance of challenges and skills, and self-realization values) were used in the present study. Cross-sectional relationships between the predictors and subjective experience indices at each timepoint replicated those observed in previous research. Hierarchical linear modeling was used to demonstrate that, as hypothesized, increases or decreases in the predictor variables between timepoints were associated with corresponding increases or decreases in the subjective experience indices. Implications for the study of intrinsic motivation are discussed. 相似文献

Abstract. Philip Clayton's work on emergence is a valuable contribution to the fields of religion, science, and philosophy. I focus on three narrow but extremely important areas of Clayton's work. First, Clayton deems that Terrence Deacon's emergence theory is difficult to accept because it is constructed from thermodynamics, thereby rendering it unable to address phenomenological issues. I examine Deacon's theory and show that development from a physics base is warranted. Furthermore, Clayton does not convincingly demonstrate that such a constructive approach is necessarily incapable of attending to mental phenomena or offer an alternative that explains the causal power of a physically nonconstructible mental realm. Second, I argue that Clayton's notion of emergentist supervenience for comprehending the mental/physical relation is unnecessarily redundant and problematic in relation to causal power. Third, I explore Clayton's alternative use of agent causation to make sense of mental properties having causal power in the world. His effort to resolve emergence difficulties by appealing to phenomenology receives primary attention. Clayton's use of emergence theory is an important contribution to the religion‐and‐science community, and I encourage further dialogue on the exchange that Clayton commences. 相似文献

This study approaches young managers’ occupational well-being through their work-related goal pursuit. The main aim was to identify content categories of personal work goals and investigate their associations with background factors, goal appraisals, burnout, and work engagement. The questionnaire data consisted of 747 young Finnish managers (23-35 years; M = 31 years) who were mostly men (85.5%). Seven work-related content categories were found on the basis of qualitative data analysis: (1) competence goals (30.5%), (2) progression goals (23.7%), (3) well-being goals (15.2%), (4) job change goals (13.7%), (5) job security goals (7.4%), (6) organizational goals (5.6%), and (7) financial goals (3.9%). ANCOVA analyses, where goal appraisals and significant background factors were controlled for, indicated that organizational goals were related to low burnout and the highest level of work engagement, whereas well-being and job change goals were related to higher burnout and lower work engagement. The study shows that the contents of young managers’ work-related goals can contribute to the understanding of individual differences in occupational well-being. 相似文献

Tyler Burge has recently argued that quasi-memory-based psychological reductionist accounts of diachronic personal identity
are deeply problematic. According to Burge, these accounts either fail to include appropriately de se elements or presuppose
facts about diachronic personal identity—facts of the very kind that the accounts are supposed to explain. Neither of these
objections is compelling. The first is based in confusion about the version of reductionism to which it putatively applies.
The second loses its force when we recognize that reductionism is a metaphysical thesis, not an epistemological one.

This article explores the question: what is it for two or more people to intend to do something in the future? In a technical phrase, what is it for people to share an intention? Extending and refining earlier work of the author’s, it argues for three criteria of adequacy for an account of shared intention (the disjunction, concurrence, and obligation criteria) and offers an account that satisfies them. According to this account, in technical terms explained in the paper, people share an intention when and only when they are jointly committed to intend as a body to do such-and-such in the future. This account is compared and contrasted with the common approach that treats shared intention as a matter of personal intentions, with particular reference to the work of Michael Bratman. 相似文献

Existing research about subjective wellbeing (SWB) in China is confined to student and urban samples, even though 60% of the
population reside in rural areas. It is reasonable to predict that there could be a rural-urban difference in SWB as there
is a marked difference in objective (socio-economic) measures of wellbeing. The present study measured SWB within a sample
of Chinese peasants living in a remote farming village. The results show that despite their relatively low socioeconomic conditions,
the rural residents’ satisfaction levels were within the normative range for the Chinese population, and generally did not
differ significantly from a previously published study in an affluent Chinese region (Hong Kong). In-depth interviews with
participants revealed that the lower living conditions in the rural area are not adverse to drive SWB below the normative
range.
