The ability to learn the direction of causal relations is critical for understanding and acting in the world. We investigated how children learn causal directionality in situations in which the states of variables are temporally dependent (i.e., autocorrelated). In Experiment 1, children learned about causal direction by comparing the states of one variable before versus after an intervention on another variable. In Experiment 2, children reliably inferred causal directionality merely from observing how two variables change over time; they interpreted Y changing without a change in X as evidence that Y does not influence X. Both of these strategies make sense if one believes the variables to be temporally dependent. We discuss the implications of these results for interpreting previous findings. More broadly, given that many real‐world environments are characterized by temporal dependency, these results suggest strategies that children may use to learn the causal structure of their environments. 相似文献

Previous research has shown that positive mood may broaden attention, although it remains unclear whether this effect has a perceptual or a postperceptual locus. In this study, we addressed this question using high-density event-related potential methods. We randomly assigned participants to a positive or a neutral mood condition. Then they performed a demanding oddball task at fixation (primary task ensuring fixation) and a localization task of peripheral stimuli shown at three positions in the upper visual field (secondary task) concurrently. While positive mood did not influence behavioral performance for the primary task, it did facilitate stimulus localization on the secondary task. At the electrophysiological level, we found that the amplitude of the C1 component (reflecting an early retinotopic encoding of the stimulus in V1) was enhanced in the positive, as compared with the neutral, mood group. Importantly, this effect appeared to be largely automatic, because it occurred regardless of the task relevance of the peripheral stimulus and prior to top-down gain control effects seen at the level of the subsequent P1 component. This early effect was also observed irrespective of a change of the target-related P300 component (primary task) by positive mood. These results suggest that positive mood can automatically boost the spatial encoding of peripheral stimuli early on following stimulus onset. This effect can eventually underlie the broadening of spatial attention, which has been associated with this specific mood state. 相似文献

Research has investigated the role of three basic psychological needs as proposed by Self-Determination Theory – autonomy, competence, and relatedness – in explaining relationship satisfaction. Research has also explored how relatedness specifically increases prosocial motivations in the individual but has not focused on the role of relatedness in shaping partners’ relationship functioning over time. This research takes a dyadic perspective that proposes that relatedness fulfillment fosters compassionate goals, which in turn predict increases in partner’s satisfaction. Forty-five heterosexual dating couples were asked about their relatedness need fulfillment, compassionate goals, and relationship satisfaction. Relationship satisfaction was assessed again four weeks later. Results showed that one’s own relatedness fulfillment, but not one’s partner’s relatedness fulfillment at Time 1 uniquely predicts partner’s increased satisfaction at Time 2, and that this is mediated by one’s own higher compassionate goals. These findings highlight the dyadic importance of having one’s needs met in promoting relationship functioning over time. 相似文献

How does the remarkable human ability for face recognition arise over development? Competing theories have proposed either late maturity (beyond 10 years) or early maturity (before 5 years), but have not distinguished between perceptual and memory aspects of face recognition. Here, we demonstrate a perception–memory dissociation. We compare rate of development for (adult, human) faces versus other social stimuli (bodies), other discrete objects (cars), and other categories processed in discrete brain regions (scenes, bodies), from 5 years to adulthood. For perceptual discrimination, performance improved with age at the same rate for faces and all other categories, indicating no domain‐specific development. In contrast, face memory increased more strongly than non‐face memory, indicating domain‐specific development. The results imply that each theory is partly true: the late maturity theory holds for face memory, and the early maturity theory for face perception. 相似文献

In this discussion I use the concept of the moral Third to designate the position in which we experience the world as lawful because repair is possible. Repair takes place through acknowledgment of harming and consequent suffering. This form of acknowledgment, coupled with social recognition, is considered by the authors to be a crucial part of the therapeutic work with victims of collective trauma, especially of torture by the Pinochet security police. In relation to Gómez’s case, I discuss how the moral Third, the representation of a lawful world, is shattered by attacks on the victim’s family. Further, the witnessing function is reversed and perverted in torture, where the torturer presents a blank face and denies the very suffering he is inducing. The experience of betrayal becomes the core issue which the therapist seeks to address through the attachment relationship itself. In relation to Kovalskys’ case I consider how the moral Third of the activists, the belief in the possibility of a world in which all can live, is attacked in order to affirm the paranoid view that “only one can live.” The lived experience of this traumatizing attack is that the child becomes imbued with the sense of not deserving life, of having gained life at the expense of the other. Helping the patient to testify publicly to her personal history and truth becomes part of the healing process in the context of collective trauma. 相似文献
