We explored the amount and timing of temporal synchrony necessary to facilitate prenatal perceptual learning using an animal model, the bobwhite quail. Quail embryos were exposed to various audiovisual combinations of a bobwhite maternal call paired with patterned light during the late stages of prenatal development and were tested postnatally for evidence of prenatal auditory learning of the familiarized call. Results revealed that a maternal call paired with a single pulse of light synchronized with one note of the five note call was sufficient to facilitate embryos’ prenatal perceptual learning of the entire call. A synchronous note occurring at the onset of the call burst was most effective at facilitating learning. These findings highlight quail embryos’ remarkable sensitivity to temporal synchrony and indicate its role in promoting learning of redundantly specified stimulus properties during prenatal development.  相似文献

According to the intersensory redundancy hypothesis (IRH), during early development, perception of nonredundantly specified properties is facilitated in unimodal stimulation as compared with bimodal stimulation. Later in development, attention becomes more flexible and infants can detect nonredundantly specified properties in both unimodal and bimodal stimulation. This study tested these predictions by assessing the development of infants' sensitivity to the orientation of an object striking a surface, information that is nonredundantly specified in visual and in audiovisual stimulation. Infants of 3, 5, and 8 months were habituated to unimodal visual or bimodal, synchronous, audiovisual films of a hammer tapping a rhythm in 1 of 2 orientations (upward vs. downward). Results demonstrated an Age × Condition interaction, where younger infants (3 and 5 months) detected the orientation change in unimodal but not bimodal stimulation, whereas older infants (8 months) detected the change in both types of stimulation. Further, in a control study, 3‐month‐olds detected the orientation change when bimodal stimulation was asynchronous, demonstrating that temporal synchrony impaired performance in the bimodal condition. These findings converge with those of prior studies and support predictions of the IRH.  相似文献

The intergenerational stake hypothesis suggests that parents are more invested in their children and experience better quality parent–child ties than do their children. In this study the authors examined variation in reports of relationship quality regarding parents and children intra‐individually (do people report better quality ties with their children than with their parents?) and whether within‐person variations have implications for well‐being. Participants age 40–60 (N = 633) reported on their relationship quality (importance, positive quality, and negative quality) with their parents and adult children. Individuals reported their relationships with children were more important and more negative than relationships with parents. Individuals with feelings that were in the opposite direction of the intergenerational stake hypothesis (i.e., greater investment in parents than children) reported poorer well‐being. The findings provide support for the intergenerational stake hypothesis with regard to within‐person variations in investment and show that negative relationship quality may coincide with greater feelings of investment.  相似文献

This study assesses the impact of socioeconomic, sociodemographic, and attitudinal characteristics of husbands and wives on the timing of marital dissolution. The primary concerns were with divorce and the intervals of marital duration before divorce occured. The analysis was based on data collected from an initial sample of 610 couples in the early years of marriage, all of whom resided within a large North Central Standard Metropolitan Statistical Area in 1978. The couples were reinterviewed seven years later in 1985 (N = 544). The data collected from the first wave of subjects were used to identify antecedent characteristics of husbands and wives, whereas, data from the second wave were used to measure the timing (tempo) of marital dissolution among the 105 couples who subsequently divorced. Partial correlation coefficients indicated that the tempo of divorce significantly varied according to the wife's employment status, occupational status, future work plans, father's education, age at marriage, gender role orientation and number of children. Moreover, a multiple classification analysis of these variables showed that under controlled conditions wives' employment status and number of children were more powerful predictors of the tempo of divorce.  相似文献

Theory and research suggest that, while embarrassment may be intrinsic to social interaction, its expression is C. taboo. Embarrassment is seen as reflecting social incompetence. As such, members make routine attempts to repress embarrassment in the self and to deny embarrassment to self and others. I call this the taboo–repression–denial hypothesis. However, despite attempts at repression and denial, members reveal embarrassment in a variety of ways, including verbally, paralinguistically/vocally, and facially/bodily. This paper is an initial investigation of emotion denial in verbal discourse. Through an analysis of embarrassment talk and non-embarrassment talk, I discover six features of the verbal context of references to embarrassment which aid in the disguise and denial of feeling: (1) verbal mitigation; (2) a link between references to embarrassment and mitigation; (3) verbal projection; (4) a link between use of “ya know”, embarrassment references, and mitigation; (5) a link between use of “I don't know”, embarrassment references, and mitigation; and (6) a link between references to embarrassment and laughter. Findings indicate verbal and nonverbal methods of emotion denial, and provide initial support for the taboo–repression–denial hypothesis.  相似文献

The study explored the characteristics and experiences of branch campus social work education programs and educators in the United States. Eighty-one branch campus social work educators in 26 states completed an online survey. Findings revealed that undergraduate and graduate branch campus social work education was primarily delivered face-to-face to nontraditional students. Half of these programs were recently established, and the majority were expected to grow. However, teaching these students was not necessarily viewed as a shared responsibility. Although some branch campus faculty reported higher workloads and limited connections to parent campus colleagues, faculty generally reported great satisfaction teaching branch campus students. Practical implications are provided.  相似文献

The damaged goods hypothesis posits that female performers in the adult entertainment industry have higher rates of childhood sexual abuse (CSA), psychological problems, and drug use compared to the typical woman. The present study compared the self-reports of 177 porn actresses to a sample of women matched on age, ethnicity, and marital status. Comparisons were conducted on sexual behaviors and attitudes, self-esteem, quality of life, and drug use. Porn actresses were more likely to identify as bisexual, first had sex at an earlier age, had more sexual partners, were more concerned about contracting a sexually transmitted disease (STD), and enjoyed sex more than the matched sample, although there were no differences in incidence of CSA. In terms of psychological characteristics, porn actresses had higher levels of self-esteem, positive feelings, social support, sexual satisfaction, and spirituality compared to the matched group. Last, female performers were more likely to have ever used 10 different types of drugs compared to the comparison group. A discriminant function analysis was able to correctly classify 83% of the participants concerning whether they were a porn actress or member of the matched sample. These findings did not provide support for the damaged goods hypothesis.  相似文献

An exploration of variables potentially related to Listening Fidelity (LF) was conducted through two separate studies. Study 1 indicated that when the potential fidelity of the stimulus message was varied as a function of the number of words and time length, the message with lowest potential fidelity produced significantly lower LF than either the moderate or high potential LF message versions. The moderate potential fidelity message produced the more normal score distribution although not significantly different LF scores than the high potential message. Differences in LF were not indicated as a function of participant sex, gender, or listening style. Study 2 found that LF and two of the three internal scoring components of LF were significantly correlated with four of five dimensions of the Watson Barker Listening Test. Continued emphasis on developing alternative cognitions and exploring listener confidence, cognitive complexity, and the specific function and relationship of LF with listening outcomes were recommended.  相似文献

This paper assesses the “integrative hypothesis” as an aid to understanding the current emergence of new religious movements appealing mainly to young persons. Four ways in which these movements reintegrate young persons into the social system are identified: adjustive socialization, combination, compensation, and redirection. The limitations of each of these as an explanation for the integrative consequences of youth culture religious movements are discussed. A distinction is made between adaptive movements which actually appear to reassimilate social “dropouts” into conventional instrumental routines, and marginal movements which appear to take converts out of conventional roles and routines, but which also perform latent tension management functions for the social system. The correlated properties of adaptive and marginal movements and the tendency for marginal movements to evolve into adaptive movements are discussed. Finally, the problem of “reductionism” in analyzing religious movements in terms of their latent integrative “functions” is discussed.  相似文献

Abstract The literature on the Goldschmidt (1978a) hypothesis has passed through distinct stages. This article is a commentary on the present status of the literature and particularly on a recent article by Barnes and Blevins (1992). Our arguments draw in large part from our previous work. Researchers in the 1970s and early 1980s were concerned mainly with replicating Goldschmidt's work. However, these studies had a number of methodological and conceptual limitations that limited closure on the debate. A new generation of research from the mid-1980s onward was premised upon addressing the limitations, including the need to incorporate indicators of nonfarm economic structure, to take spatial or geographic features into account, and to adequately conceptualize farm structure. Barnes and Blevins (1992) disregard these inroads, evident in that their article repeats earlier arguments, offers solutions to problems addressed a decade earlier, and is vulnerable to its own methodological problems. To move inquiry forward, new directions for studies concerned with the broader issues raised by Goldschmidt are suggested.  相似文献

Canadian fertility trends: a further test of the Easterlin Hypothesis   总被引:1,自引:0,他引:1  
Selon Richard Easterlin, le taux de fertilite d'une cohorte est inversement proportionnel a sa taille relative. C'est principalement aux Etats-Unis qu'on a trouve des donnees
peut-itre pas a ce pays. En general, il semble qu'au Canada les taux de fertilite relatifs de grosses cohortes sont plus Pleves que ceux de cohortes plus petites, et ceci malgre le fait que les taux de fertilite ont diminue pour toutes les cohortes au cours des dernieres annees. Lorsque I'on examine la taille relative des cohortes en contrdant les effets d'ige et de periode, la relation entre la taille de la cohorte et son taux de fertilitP disparait completernent ce qui reduit plus encore la validite de I'hypothPse de Easterlin
Richard Easterlin has argued that the fertility rate of a cohort is inversely related to the relative size of that cohort. Evidence to support this proposition has been derived primarily from studies in the United States. A breakdown of Canadian fertility trends to decompose age, period and cohort effects suggests that Easterlin's hypothesis may not hold for the Canadian situation. Overall, larger Canadian cohorts appear to have higher relative fertility rates than do smaller cohorts, despite the fact that fertility rates have declined across all cohorts in recent years. Focusing on relative cohort size, and controlling for age and period effects, the relationship between cohort size and fertility disappears completely further minimizing the validity of the Easterlin Hypothesis. supportant cette these. Une analyse de la fertilite au Canada, qui distingue entre les effets d'ige, de periode et de cohorte indique que I'hypothese de Easterlin ne s'applique  相似文献

A double jeopardy hypothesis argues that the combined negative effects of occupying two stigmatized statuses are greater than occupying either status alone. Applying this framework to elderly persons, it can be argued that being female and “old” elderly has more negative consequences than being male and “old” elderly, male and “young” elderly or female and “young” elderly. An empirical test of this hypothesis, using both an objective (mental health status) and a subjective (perceived well-being) indicator as the dependent variable, reveals a confirmation of double jeopardy using the objective quality of life indicator, but not the subjective indicator. Additional analyses of the factors affecting each of the dependent variables, adds further support for the uniqueness of old, elderly women as a social category.  相似文献

Abstract

Analysis of survey data from faculty at fifteen colleges and universities in a large Midwestern metropolitan area supports earlier speculations that certain attributes unique to academia are predictive of differential participation in several aspects of socio-political life. Scholarly commitments and working in a field that studies socio-political issues per se are associated with liberal attitudes, casting votes for liberal candidates, and overt involvement in radical political activities. Tendencies for these associations were observed in both secular and church-related schools. Contrary to critics of the recent Ladd and Lipset studies, there is a clear tendency for faculty with liberal covert attitudes to translate them into overt participation in liberal and radical political activities.  相似文献

Abstract Both politicians and voters were asked to predict outcomesof two Oregon ballot measures in 1982. As expected, politicians'predictions always were closer to the mark than voters' were.Further, voters showed stronger signs of wishful thinking (the"Looking-Glass effect") in their predictions than did politicians.Using published preelection polls apparently improved politicians'accuracy in 1982, as well as voters' accuracy in a separate1984 survey. No other sources of data improved predictive accuracy.Findings have implications for theories of representative governmentand are consistent with a new theory of public opinion.  相似文献

Teenage parenthood is an often-discussed topic in family economics since it has been shown to affect many outcomes for the teen, child, and household. Using a nationally representative longitudinal panel of American teenagers and their parents, two questions related to the probability of teenage parenthood are examined. First, how do predictions of this occurrence made by the teenager’s parents vary across the population? Second, how does the accuracy of these predictions vary? The actual prevalence and variance of teenage parenthood are also examined, and the determinants of its occurrence are estimated. Among other results, expectations and their accuracy are found to differ substantially across socioeconomic status and some demographics such as race and religion. The average American parent underestimates the probability their child will become a teen parent by only a small amount, but within certain demographic groups this outcome is considerably underestimated, and in others it is overestimated. These differences help explain the variability in teen parenthood effects, and more broadly, the analysis serves as a test of parents’ ability to judge their childrens’ future outcomes.  相似文献

This article outlines the elements of a more robust symbolic interactionist theory of interpersonal processes. I argue that George Herbert Mead's conceptualization of interaction processes can be extended to explain not only micro‐level social processes but also key elements of meso‐ and macro‐level dynamics. By expanding Mead's and more recent symbolic interactionist theorizing, and incorporating key ideas from other theoretical traditions outside symbolic interactionism proper, it becomes possible to develop a theory of interaction that fills in important conceptual gaps in theories on the dynamics of micro‐, meso‐, and macro‐level social phenomena.  相似文献

This article addresses a general problem in media sociology – how to understand the media both as an internal production process and as a general frame for categorizing the social world, with specific reference to a version of this problem in recent work on media within Bourdieu’s field-based tradition of research (work previously reviewed by Rodney Benson in Theory and Society28). It argues that certain problems arise in reconciling this work’s detailed explanations of the media field’s internal workings (and the interrelations of that field’s workings to the workings of other fields) and general claims made about the “symbolic power” of media in a broader sense. These problems can be solved, the author argues, by adopting the concept of meta-capital developed by Bourdieu himself in his late work on the state, and returning to the wider framework of symbolic system and symbolic power that was important in Bourdieu’s social theory before it became dominated by field theory. Media, it is proposed, have meta-capital over the rules of play, and the definition of capital (especially symbolic capital), that operate within a wide range of contemporary fields of production. This level of explanation needs to be added to specific accounts of the detailed workings of the media field. The conclusion points to questions for further work, including on the state’s relative strength and the media’s meta-capital that must be carried out through detailed empirical work on a global comparative basis.  相似文献
