Television viewing and picture book reading are prevalent activities during toddlerhood, and research has shown that toddlers can imitate from both books and videos after short delays. This is the first study to directly compare toddlers' long-term retention rates for target actions learned from a video or book. Toddlers (N=158) at 18- and 24-months of age saw an experimenter demonstrating how to make a novel three-step toy rattle via a prerecorded video or a picture book. The toddlers' imitation of the target actions was tested after a specific delay (e.g., 2, 4 weeks), and their performance was compared with that of age-matched controls who did not see a demonstration. The 18-month-olds retained the target actions for 2 weeks, exhibiting forgetting at 4 weeks, whereas the 24-month-olds retained the information for up to 4 weeks, exhibiting forgetting at 8 weeks. Retention rates for books and videos did not differ at either age. These findings demonstrate very impressive retention from a brief two-dimensional media demonstration, and they contribute to our overall understanding of long-term memory processes during infancy. 相似文献

When sample information is combined, it is generally considered normative to weight information based on larger samples more
heavily than information based on smaller samples. However, if samples appear likely to have been drawn from different subpopulations,
it is reasonable to combine estimates of these subpopulation means (typically, the sample means) without weighting these estimates
by sample size. This study investigated whether laypeople are influenced by the likelihood of samples coming from the same
population when determining how to combine information. In two experiments we show that (1) implied binomial variability affected
participants’ judgments of the likelihood that a sample was drawn from a given population, (2) participants' judgments were
more affected by sample size when samples were implied to be drawn randomly from a general population, compared to when they
were implied to be drawn from different subpopulations, and (3) people higher in numeracy gave more normative responses. We
conclude that when determining how to weight and combine samples, laypeople use not only the provided data, but also information
about likelihood and sampling processes that these data imply. 相似文献

Very few studies have examined the cognitive advantages of bilingualism during the first two years of development, and a majority of the studies examining bilingualism throughout the lifespan have focused on the relationship between multiple languages and cognitive control. Early experience with multiple language systems may influence domain‐general processes, such as memory, that may increase a bilingual child’s capacity for learning. In the current study, we found that bilingual, but not monolingual, infants were able to generalize across cues at 18 months. This is the first study to show a clear bilingual advantage in memory generalization, with more equal or balanced exposure to each language significantly predicting ability to generalize.

Which emotions underlie our positive experiences of art? Although recent evidence from neuroscience suggests that emotions play a critical role in art perception, no research to date has explored the extent to which specific emotional states affect aesthetic experiences or whether general physiological arousal is sufficient. Participants were assigned to one of five conditions-sitting normally, engaging in 15 or 30 jumping jacks, or viewing a happy or scary video-prior to rating abstract works of art. Only the fear condition resulted in significantly more positive judgments about the art. These striking findings provide the first evidence that fear uniquely inspires positively valenced aesthetic judgments. The results are discussed in the context of embodied cognition.

Science and technology, including nanoscale science and technology, influences and is influenced by various discourses and areas of action. Ableism is one concept and ability expectation is one dynamic that impacts the direction, vision, and application of nanoscale science and technology and vice versa. At the same time, policy documents that involve or relate to disabled people exhibit ability expectations of disabled people. The authors present ability expectations exhibited within two science and technology direction documents from Asia, as well as in two policy documents generated and influenced by disabled people from Asia. As well, the authors discuss the impact of the ability expectations exhibited in these four documents with respect to the relationship between science and technology and disabled people. 相似文献

Describing a face in words can either hinder or help subsequent face recognition. Here, the authors examined the relationship between the benefit from verbally describing a series of faces and the same-race advantage (SRA) whereby people are better at recognizing unfamiliar faces from their own race as compared with those from other races. Verbalization and the SRA influenced face recognition independently, as evident on both behavioral (Experiment 1) and eye movement measures (Experiment 2). The findings indicate that verbalization and the SRA each recruit different types of configural processing, with verbalization modulating face learning and the SRA modulating both face learning and recognition. Eye movement patterns demonstrated greater feature sampling for describing as compared with not describing faces and for other-race as compared with same-race faces. In both cases, sampling of the eyes, nose, and mouth played a major role in performance. The findings support a single process account whereby verbalization can influence perceptual processing in a flexible and yet fundamental way through shifting one's processing orientation. 相似文献

Perceptions of age influence how we evaluate, approach, and interact with other people. Based on a paramorphic human judgment model, the present study investigates possible determinants of accuracy and bias in age estimation across the adult life span. For this purpose, 154 young, middle-aged, and older participants of both genders estimated the age of 171 faces of young, middle-aged, and older men and women, portrayed on a total of 2,052 photographs. Each face displayed either an angry, fearful, disgusted, happy, sad, or neutral expression (FACES database; Ebner, Riediger, & Lindenberger, 2010). We found that age estimation ability decreased with age. Older and young adults, however, were more accurate and less biased in estimating the age of members of their own as compared with those of the other age group. In contrast, no reliable own-gender advantage was observed. Generally, the age of older faces was more difficult to estimate than the age of younger faces. Furthermore, facial expressions had a substantial impact on accuracy and bias of age estimation. Relative to other facial expressions, the age of neutral faces was estimated most accurately, while the age of faces displaying happy expressions was most likely underestimated. Results are discussed in terms of methodological and practical implications for research on age estimation. 相似文献

On the basis of their experiences with pregnant patients in their practice, obstetrician/gynecologists estimated the posterior probability of Down syndrome given a positive screening result. They also estimated the base rate of Down syndrome in their practice, along with the hit and false alarm rates for the screening test; for each subject, these numbers were combined to calculate a posterior probability to which the initial estimated posterior probability could be compared. Physicians gave highly consistent estimates when asked to think about their past experiences in terms of event frequencies. However, those told to respond using single event probabilities or to use past experiences to predict prospective frequencies gave inconsistent Bayesian estimates. Thus, when making Bayesian judgments based on real life experience, natural frequency formats only lead to better judgments, compared with single event probability formats, if people think retrospectively, not when using past experiences to make prospective predictions.
