The ability of middle-aged adults to recall their body size and events occurring up to 40 years earlier was assessed. Ninety-one
subjects recalled their relative height, weight, and fatness during childhood, early adolescence and late adolescence. Accuracy
of these memories was compared with the accuracy of current reports. The ability to accurately date benchmarks of their maturation
such as menarche and year of maximal growth in height was also examined. Accuracy of reports did not decline uniformly over
time. In general, reports of childhood physical characteristics were at least as accurate as reports of current characteristics;
that is, they did not differ significantly from current reports. Males were less accurate in their reports of relative height
and fatness during early adolescence and childhood.

Errors in child speech show that some children initially formulate tense-hopping and subject-auxiliary inversion as copying without deletion. Other errors suggest that some children may formulate other movement rules as deletion without copying. A claim about the nature of the language acquisition device is made on the basis of our analysis of these errors: the language acquisition device formulates hypotheses about transformations in terms of basic operations. The basic-operations hypothesis predicts that for any transformation which is composed of more than one basic operation, there exists a class of errors in child speech correctly analyzed as failure to apply one (or more) of the operations specified in the adult formulation of the rule. 相似文献

A widely accepted view describes gender-role inequality as less prevalent among the middle class than the working class. Gender-role inequality within the intact nuclear family is asserted to be a syndrome characterized by unequal husband—wife authority, rigid division of household labor, and greater freedom in leisure pursuits for the husband. This view is generally unsupported by the findings of the present study, a secondary analysis of a sample survey conducted in Houston in 1969–1970. Two classes (working and middle) were compared, with ethnicity (Anglo, Black, Mexican-American) and sex controlled. Questionnaire items concerned leisure-time freedom for wives, gender differences in children's socialization, and sexual division of labor in the household. Differences between groups were generally small and inconsistent. In some cases, sexual and ethnic differences were greater than those of class. An intercorrelation matrix revealed few significant correlations between egalitarian responses to the various items, suggesting that egalitarianism or its opposite is not a syndrome.This paper utilized data collected on a project partially supported by NIMH Grant No. MH 15708. Computer services were provided by the Institute of Computer Sciences, Baylor College of Medicine, Houston, Texas, supported by NIH Grant No. RR 00259, and the Institute for Computer Services and Applications, Rice University, Houston, Texas.

Abstract— The studies described here are the first to demonstrate that a nonhuman primate species is capable of responding to pictorial depth information during infancy. In two experiments, pigtailed macaque (Macaca nemestrina) infants were tested for responsivity to the pictorial depth cites of texture gradient/linear perspective and relative size. The procedures were adapted from human studies and are based on the proclivity of infants to reach more frequently to closer objects than to objects that are farther away. The stimulus displays included two equidistant objects that, when viewed monocularly, appear separated in space because of an illusion created by pictorial depth cues. When presented with these displays, animals reached significantly more often to the apparently closer objects under monocular conditions than under binocular conditions. These findings suggest that infant macaques are sensitive to pictorial depth information, the implication being that this ability has ancient phytogenetic origins and ix not learned from exposure to the conventions of Western art. 相似文献

This three-part study demonstrates that perceptual order can influence the integration of acoustic speech cues. In Experiment 1, the subjects labeled the [s] and [∫] in natural FV and VF syllables in which the frication was replaced with synthetic stimuli. Responses to these “hybrid” stimuli were influenced by cues in the vocalic segment as well as by the synthetic frication. However, the influence of the preceding vocalic cues was considerably weaker than was that of the following vocalic cues. Experiment 2 examined the acoustic bases for this asymmetry and consisted of analyses revealing that FV and VF syllables are similar in terms of the acoustic structures thought to underlie the vocalic context effects. Experiment 3 examined the perceptual bases for the asymmetry. A subset of the hybrid FV and VF stimuli were presented inreverse, such that the acoustic and perceptual bases for the asymmetry were pitted against each other in the listening task. The perceptual bases (i.e., the perceived order of the frication and vocalic cues) proved to be the determining factor. Current auditory processing models, such as backward recognition masking, preperceptual auditory storage, or models based on linguistic factors, do not adequately account for the observed asymmetries. 相似文献

The present study investigated the effects of self-perceptions on the donating behavior of 43 fourth-grade students. The children had two opportunities to donate gum to another class. Half of the students received feedback after the first donation period indicating that they were particularly generous. These children subsequently gave more than children in the control group (p<.05). Sociometric measures indicated that the perceptions children had of themselves and others were related to donating. The results were similar for both males and females. Children process new information into their cognitive systems. The resulting cognitions help guide future behaviors. 相似文献

New technologies enable retailers to collect large amounts of information about consumers, which might lead to ethical issues and risks of individuals' privacy loss. However, consumers might choose to disclose information to retailers when they perceive that the information would generate more benefits for themselves rather than for the retailer. Since little research has been done to explain the role of age in disclosing personal information to third parties, the present study investigates the difference in the perception of one's own control when it comes to the usage of privacy-threatening technology depending on respondents' age. Drawing upon uses and gratification theory, the present study explores the response of consumers from four generational cohorts towards the facial recognition technology in retailing. Results reveal that the locus of control over information collected by the technology is neither related to the age of consumers nor to their knowledge of a specific technology used to collect their personal data. Instead, consumers' expected gratifications (in terms of economic and utilitarian) vary across different age groups. Implications for practitioners are discussed. 相似文献

Children's daily contexts shape their experiences. In this study, we assessed whether variations in infant placement (e.g., held, bouncy seat) are associated with infants' exposure to adult speech. Using repeated survey sampling of mothers and continuous audio recordings, we tested whether the use of independence-supporting placements was associated with adult speech exposure in a Southeastern U.S. sample of 60 4- to 6-month-old infants (38% male, predominately White, not Hispanic/Latinx, from higher socioeconomic status households). Within-subject analyses indicated that independence-supporting placements were associated with exposure to fewer adult words in the moment. Between-subjects analyses indicated that infants more frequently reported to be in independence-supporting placements that also provided posture support (i.e., an exersaucer) were exposed to relatively fewer adult words and less consistent adult speech across the day. These findings indicate that infants' opportunities for exposure to adult speech ‘in the wild’ may vary based on immediate physical context. 相似文献

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean rs = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition. 相似文献
