A prenatal intervention designed to prevent the onset of major depressive episodes (MDEs) during pregnancy and postpartum was pilot tested at a public sector women’s clinic. The Mamás y Bebés/Mothers and Babies Course is an intervention developed in Spanish and English that uses a cognitive-behavioral mood management framework, and incorporates social learning concepts, attachment theory, and socio-cultural issues. The four goals of this project were to develop the intervention, assess its acceptability, test the feasibility of conducting a randomized trial with public sector patients, and obtain estimates of its effect size. Forty-one pregnant women at high risk for developing MDEs were randomized to the Mothers and Babies Course (n = 21) or a comparison condition (n = 20). Assessments occurred during pregnancy and at 1, 3, 6, and 12 months postpartum. Differences in terms of depression symptom levels or incidence of MDEs between the two groups did not reach statistical significance in this pilot trial. However, the MDE incidence rates of 14% for the intervention condition versus 25% for the comparison condition represent a small effect size (h = 0.28) that will be further examined in a larger scale study. The intervention was well received by the participants and implementation of a randomized trial appeared quite feasible as indicated by our follow-up rate of 91% at 12 months. Implications for the continuing development of preventive interventions for perinatal depression are discussed. 相似文献

Contrary to rational Expected Monetary Value (EMV) predictions that no money will be transferred in Trust Games, in experiments players make positive transfers. Theorists have proposed modifying the Sender's utility function while retaining utility‐maximization assumptions to account for this behavior. Such accounts assume that Senders can grasp the possible outcomes of their choices, their probabilities, and utilities. In reality, however, Senders' choices are unexpectedly complex, and the assumption that they approximate expected utility maximization is highly implausible. Instead, we suggest that Senders are guided by general propensities to trust others. Two experiments examine the effect of inducing consequential thought on Sender behavior. One induced consequential thought directly; the other did so indirectly. The amount sent was significantly reduced following either manipulation. This suggests that models of Sender behavior in Complex Trust Games should not assume that participants routinely engage in consequential thinking (CT) of the depth that would be required for utility maximization.

We offer a constructive critique of Regulatory Engagement Theory (Higgins, E. T. (2006). Value from hedonic experience and engagement. Psychological Review, 113(3), 439–460.; Higgins, E. T., and Scholer, A. A. (2009). Engaging the consumer: The science and art of the value creation process. Journal of Consumer Psychology, 19(2).). After highlighting the major tenets of the theory and its main contributions, we identify some of its conceptual ambiguities. We then argue that the hedonic and intensity components of value may not be psychologically separable in that experiences acquire their hedonic quality through their intensity. We next discuss why the various determinants of strength of engagement proposed by the theory may not all operate through the same process. Even the regulatory fit phenomenon seems to involve more than one process. We conclude by suggesting that many strength-of-engagement effects may reflect feelings-as-information inferences consistent with the Generalized Affect-as-Information Model of judgment (GAIM; Pham, M. T. (2008). The lexicon and Grammar of Affect-as-Information: The GAIM. In M. Wanke (Ed.), Social psychology of consumer behavior. New York: Psychology Press.). 相似文献

Over the last decade, iterated learning studies have provided compelling evidence for the claim that linguistic structure can emerge from non-structured input, through the process of transmission. However, it is unclear whether individuals differ in their tendency to add structure, an issue with implications for understanding who are the agents of change. Here, we identify and test two contrasting predictions: The first sees learning as a pre-requisite for structure addition, and predicts a positive correlation between learning accuracy and structure addition, whereas the second maintains that it is those learners who struggle with learning and reproducing their input who add structure to it. This prediction is hard to test in standard iterated learning paradigms since each learner is exposed to a different input, and since structure and accuracy are computed using the same test items. Here, we test these contrasting predictions in two experiments using a one-generation artificial language learning paradigm designed to provide independent measures of learning accuracy and structure addition. Adults (N = 48 in each study) were exposed to a semi-regular language (with probabilistic structure) and had to learn it: Learning was assessed using seen items, whereas structure addition was calculated over unseen items. In both studies, we find a strong positive correlation between individuals' ability to learn the language and their tendency to add structure to it: Better learners also produced more structured languages. These findings suggest a strong link between learning and generalization. We discuss the implications of these findings for iterated language models and theories of language change more generally. 相似文献

This longitudinal study investigated the relation between children's early use of symbols and their later understanding of representation and metarepresentation. The performance of 64 children on DeLoache's (1987) scale model task was measured at 30, 36, and 42 months, and their false belief understanding was measured at 42 and 48 months. Language and executive function measures were taken at each time point. Scale model performance was related to concurrent and subsequent false belief understanding, and scale model performance both predicted and was predicted by language across time. Language predicted false belief within and across time, and with increasing age it mediated the relation between success on the scale model task and false belief understanding. Although executive function was related to performance on scale model and theory of mind tasks, it did not mediate the relation between these. This study provides evidence suggesting that symbolic functioning, language, and theory of mind may form part of a single skill set underlying symbolic representation. 相似文献

Individual choices are commonly taken to manifest personal preferences. The present study investigated whether social and statistical cues influence young children's inferences about the generalizability of preferences. Preschoolers were exposed to either 1 or 2 demonstrators’ selections of objects. The selected objects constituted 18%, 50%, or 100% of all available objects. We found that children took a single demonstrator's choices as indicative only of his or her personal preference. However, when 2 demonstrators made the same selection, then children inferred that it generalized to other agents of the same kind as the original demonstrator's, but not to agents of a different kind. Lastly, only when both demonstrators blatantly violated random selection (i.e., in the 18% condition) did children generalize the preference even to an agent of a different kind. Thus, from a young age, social and statistical cues inform children's naïve sociology. 相似文献

Using an ecological framework, this 2‐wave longitudinal study examined the effects of parentification on youth adjustment across the transition to adolescence in a high‐risk, low‐income sample of African American (58%) and European American (42%) mother–child dyads (T1 Mage = 10.17 years, T2 Mage = 14.89 years; 52.4% female). Children's provision of family caregiving was moderately stable from early to late adolescence. Emotional and instrumental parentification evidenced distinct long‐term effects on adolescents' psychopathology and the quality of the parent–child relationship. Ethnicity moderated these relations. Emotional and instrumental parentification behaviors were associated with predominantly negative outcomes among European American youth in the form of increased externalizing behavior problems and decreased parent–child relationship quality, whereas emotional parentification was associated with positive outcomes among African American youth in the form of increased parent–child relationship quality, and instrumental parentification was neutral. These findings support a multidimensional view of parentification as a set of culturally embedded phenomena whose effects can only be understood in consideration of the context in which they occur. 相似文献
