Mechanical Turk (MTurk), an online labor system run by Amazon.com, provides quick, easy, and inexpensive access to online research participants. As use of MTurk has grown, so have questions from behavioral researchers about its participants, reliability, and low compensation. In this article, we review recent research about MTurk and compare MTurk participants with community and student samples on a set of personality dimensions and classic decision‐making biases. Across two studies, we find many similarities between MTurk participants and traditional samples, but we also find important differences. For instance, MTurk participants are less likely to pay attention to experimental materials, reducing statistical power. They are more likely to use the Internet to find answers, even with no incentive for correct responses. MTurk participants have attitudes about money that are different from a community sample's attitudes but similar to students' attitudes. Finally, MTurk participants are less extraverted and have lower self‐esteem than other participants, presenting challenges for some research domains. Despite these differences, MTurk participants produce reliable results consistent with standard decision‐making biases: they are present biased, risk‐averse for gains, risk‐seeking for losses, show delay/expedite asymmetries, and show the certainty effect—with almost no significant differences in effect sizes from other samples. We conclude that MTurk offers a highly valuable opportunity for data collection and recommend that researchers using MTurk (1) include screening questions that gauge attention and language comprehension; (2) avoid questions with factual answers; and (3) consider how individual differences in financial and social domains may influence results.

The purpose of this prospective, controlled study was to compare neurodevelopmental and social outcomes at 2 years of age for children treated with extracorporeal membrane oxygenation (ECMO; n = 25) to those of children with severe respiratory illness treated with conventional methods (CT; n = 16) and to matched, healthy full-term (FT; n = 29) children. Mothers' parenting attitudes and children's mental, motor, language, exploratory play, and social competence skills were assessed. A retrospective chart review was also undertaken to further describe the groups with respect to the results of neuroimaging, audiologic, and neuromotor examinations. The FT group had significantly higher mental, motor, and language scores as compared to the ECMO and CT groups. Groups did not differ on measures of behavior, social competence, exploratory play skills, or parental attitudes. Specifically for the ECMO group, there was a trend toward language being more problematic than other areas of development. In general, the data demonstrate that severe respiratory complications, regardless of type of treatment, place children at increased risk for neurodevelopmental difficulties. 相似文献

One of the foremost champions of the ‘Dark Mother’ today is the overwhelmingly white feminist spirituality movement, based in the United States and Europe. Over the past twenty-five years, white spiritual feminists have approached the figure of the Dark Mother, which is borrowed from Hindu, African and Christian sources, with a uniquely fraught mix of longing, envy, hope, fear and guilt. This article first discusses the explicit justifications that white spiritual feminists offer for the incorporation of the Dark Mother into their religiosity, including their analysis of how the concepts of ‘lightness’ and ‘darkness’ are deployed and gendered in patriarchal religions. It then argues that, contrary to spiritual feminist claims, the Dark Mother as such does not exist cross-culturally but is rather the joint creation of the history of religions, Jungian psychology and spiritual feminist ingenuity, and that she is constructed and utilised primarily as a means of working through white racial guilt. 相似文献

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex. 相似文献

Relationships between infant negative reactivity and self-regulation, parenting self-efficacy, and child weight outcomes were examined. Greater observed negative reactivity predicted more child weight gain when mothers had lower parenting self-efficacy. Lower mother-reported self-regulation predicted a greater child weight status. Results highlight potential early risk/protective factors. 相似文献

In this paper, we examine dominant Christian conservative narratives of the origins of same-sex sexuality. Critics of the Christian right usually focus on a narrative of choice that Christian right organisations and activists use to explain the origins of same-sex sexuality. A choice narrative grounds a range of political positions and, in many contexts, effectively neutralises both claims of discrimination and public support for potential legal remedies. On the other hand, a narrative of development receives less attention from critics of the Christian right. Although it cannot be reduced to its political efficacy, the narrative of development has a political as well as therapeutic function. Indeed, this narrative circulates tacitly through a different set of public debates than those usually associated with the narrative of choice, including debates over programmes geared to eliminate antigay harassment in public schools. The two narratives create tensions within Christian conservative thought that can destabilise antigay social and political projects. 相似文献

This study examined the contribution of child temperament, parenting, and their interaction on inhibitory control development in a sample of maltreated and non‐maltreated preschool children. One hundred and eighteen mother–child dyads were drawn from predominantly low‐income, rural communities. Dyads participated in a laboratory session in which maternal warm autonomy support, warm guidance, and strict/hostile control were observationally coded during a joint teaching task. Independent assessments of children's inhibitory control were obtained, and observers rated children's temperament. After relevant covariates, including income, maternal education, and child age and IQ were controlled for, there were no differences between the maltreatment and non‐maltreatment groups in either children's inhibitory control or mothers' behaviours in the laboratory session. Even after much of the variance in children's inhibitory control was accounted for from the covariates, children's temperamental negativity moderated the effects of warm autonomy support on inhibitory control in both maltreatment and non‐maltreatment groups. Temperamentally negative children whose mothers displayed more warm autonomy support showed greater inhibitory control, at levels on par with low‐negative children. Findings suggest that heterogeneity in children's self‐regulation may be due in part to individual differences in sensitivity to caregiver support for children's independence, even among those exposed to maltreatment.

Previous research on the association between maltreatment in childhood and later religious beliefs and behaviours suggests that maltreatment may have either negative or positive influences on religiosity. However, methodological limitations of previous studies may limit their generalisability. The present study attempted to address these limitations. We examined associations between childhood physical, sexual, and emotional abuse and several dimensions of adult religiosity in a large sample of college students (N = 763). Associations between child maltreatment and religiosity were weak (rs ≤ 0.09). After controlling for possible demographic confounds, the only significant association was between childhood emotional abuse and religious questing. 相似文献
