In visually complex environments, numerous items compete for attention. Infants may exhibit attentional efficiency—privileged detection, attention capture, and holding—for face‐like stimuli. However, it remains unknown when these biases develop and what role, if any, experience plays in this emerging skill. Here, nursery‐reared infant macaques' (Macaca mulatta; n = 10) attention to faces in 10‐item arrays of nonfaces was measured using eye tracking. With limited face experience, 3‐week‐old monkeys were more likely to detect faces and looked longer at faces compared to nonfaces, suggesting a robust face detection system. By 3 months, after peer exposure, infants looked faster to conspecific faces but not heterospecific faces, suggesting an own‐species bias in face attention capture, consistent with perceptual attunement. 相似文献

The ability to discriminate social signals from faces is a fundamental component of human social interactions whose developmental origins are still debated. In this study, 5-year-old (N = 29) and 7-year-old children (N = 31) and adults (N = 34) made perceptual similarity and trustworthiness judgments on a set of female faces varying in level of expressed trustworthiness. All groups represented perceived similarity of the faces as a function of trustworthiness intensity, but such representation becomes more fine-grained with development. Moreover, 5-year-olds' accuracy in choosing the more trustworthy face in a pair varied as a function of children's score at the Test of Emotion Comprehension, suggesting that the ability to perform face-to-trait inferences is related to the development of emotional understanding. 相似文献

This study employed an exploratory sequential mixed-methods design to examine the intersection of race and gender among Black American adolescents, aged 11–19. The quantitative component (n = 344) used survey data to examine gender differences in peer-perpetrated and adult-perpetrated racial discrimination experiences, and no gender differences were evident. Qualitative data (n = 42) probed how males and females interpret discrimination experiences given the intersection of race and gender. Although the majority of participants believed that Black males and females have similar experiences, some believed that Black males face more racial discrimination. However, analyses revealed social disadvantages for Black females given that they report inappropriate comments and unwelcome hair touching and limited opportunities for interracial dating compared with Black males. 相似文献

The development of human body perception has long been investigated, but little is known about its early origins. This study focused on how a body part highly relevant to the human species, namely the hand, is perceived a few days after birth. Using a preferential‐looking paradigm, 24‐ to 48‐hr‐old newborns watched biomechanically possible and impossible dynamic hand gestures (Experiment 1, N = 15) and static hand postures (Experiment 2, N = 15). In Experiment 1, newborns looked longer at the impossible, compared to the possible, hand movement, whereas in Experiment 2 no visual preference emerged. These findings suggest that early in life the representation of the human body may be shaped by sensory‐motor experience. 相似文献

We examined children’s spontaneous information seeking in response to referential ambiguity. Children ages 2–5 (n = 160) identified the referents of familiar and novel labels. We manipulated ambiguity by changing the number of objects present and their familiarity (Experiments 1 and 2), and the availability of referential gaze (Experiment 2). In both experiments, children looked to the face of the experimenter more often while responding, specifically when the referent was ambiguous. In Experiment 2, 3- to 4-year olds also demonstrated sensitivity to graded referential evidence. These results suggest that social information seeking is an active learning behavior that could contribute to language acquisition in early childhood. 相似文献

Adult Syrian hamster females (Mesocricetus auratus) learn to discriminate against familiar heterospecific males (Turkish hamster, M. brandti). We investigated whether females learn to avoid any heterospecific male after exposure to just one heterospecific male.
We predicted that, after being exposed to one heterospecific male, a female would avoid mating not only with that familiar
male but also with any unfamiliar heterospecific male. We exposed females to a heterospecific male across a wire-mesh barrier
for 8 days and then paired the female with (a) that same heterospecific male or (b) an unfamiliar heterospecific male. Females
exhibited lordosis faster and for a longer duration toward the unfamiliar than toward the familiar heterospecific male. However,
females were similarly aggressive toward familiar and unfamiliar heterospecific males. Perhaps exposure to stimuli from several
heterospecific males (a likely scenario in the wild) would result in females behaving similarly toward familiar and unfamiliar
heterospecific males. 相似文献

The claim that very young infants can imitate rests largely on reports that infants match adult displays of mouth opening (MO) and tongue protrusion (TP). Recent reviews suggest that only tongue protruding is reliably matched by young infants. This study tests the proposal that infants' "imitation" of tongue protruding reflects a coincidental match between a sight that infants find interesting and a behavior by which infants express interest. In Study 1, 4-week-old infants who looked longer at a nonsocial light display also produced TPs at higher rates than infants showing less interest. In Study 2, 4-week-old infants showed more interest in (looked longer at) a tongue-protruding adult face than a mouth-opening face. Study 3 tracked 2 infants' responses to interesting objects for several weeks before and after the onset of manual reaching. Both infants produced tongue protrusions in response to objects within reach before but not after reaching developed. Together, the results of the 3 studies suggest that infants' tongue protrusions in response to a tongue-protruding adult reflect very early attempts at oral exploration of interesting objects. 相似文献

To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tracking using a face-distractor paradigm. The early RPs were related to a lower attention bias to fearful faces compared to happy and neutral faces after controlling for temperamental negative affectivity. This suggests that early RPs are related to the processing of emotional information later during infancy. 相似文献

Although the impact of early adverse experience on neural processing of face familiarity has been studied, research has not taken into account disordered child behavior. This work compared the neural processing of familiar versus strangers' faces in 47 institutionalized children with a mean age of 54 months to determine the effects of (a) the presence versus absence of atypical social behavior and (b) inhibited versus indiscriminant atypical behavior. Results revealed a pattern of cortical hypoactivation in institutionalized children manifesting atypical social behavior and that inhibited children displayed larger neural response to a caregiver's face than to the stranger's, while indiscriminant children did not discriminate between stimuli. These findings suggest that neural correlates of face familiarity are associated with social functioning in institutionalized children. 相似文献

Gender differences in computer-related attitudes have been reported in school children of all ages. Females express more negative
attitudes than males when asked to explicitly endorse attitude statements. This gender difference may be compounded by females
expressing attitudes consistent with their psychological gender. This study uses an art-based methodology to assess the computer-related
attitudes of 395 primary school children (aged 5 to 11). A significant difference occurs in the gender drawn by the children.
Whilst 30% of females draw males, only 4% of males draw females. Additionally, older females draw proportionally less smiling
faces. These results are consistent with more traditional assessments of attitude which indicate that females’ attitudes towards
computers become more negative as they progress through the educational system. The art-based methodology also identified
similar proportions of females holding negative attitudes as do more traditional assessments, suggesting ecological validity
for the gender differences in computer attitudes. The implications for computer-related education are discussed. 相似文献

Two independent cohorts (N = 155, N = 126) of infants at high and low risk for autism spectrum disorder (ASD) were followed prospectively between 6 and 36 months of age, when n = 46 were diagnosed with ASD. Gaze to adult faces was coded—during a developmental assessment (Cohort 1) or a play interaction (Cohort 2). Across both cohorts, most children developing ASD showed sharp declines in gaze to faces over time, relative to children without ASD. These findings suggest that declining developmental trajectories may be more common than previously recognized by retrospective methods. Trajectory-based screening methods could potentially identify children in the early stages of symptom onset and allow for early intervention before the full disorder has developed. 相似文献

Both the psychological and criminological fields have long hypothesized the mechanisms that influence desistance from violent offending, but few studies have focused on violent females. This study identifies patterns of violent behavior across 7 years among 172 females and 172 matched males ages 15–24, testing if heterogeneity in violent offending is linked to (a) developmental change in impulse control and (b) attainment of adult milestones. Fewer females persist in violence (25%) than males (46%); 19% of males increase in violent behavior. Females who develop impulse control and are employed are more likely to desist from violence. Violent offending is unrelated to other adult milestones. Developmental increases in impulse control may trigger desistance, while employment may maintain desistance from violence. 相似文献

6 1-month-old infants and 6 2-month-old infants each viewed 3 faces (his mother's, a strange woman's, and a strange man's) while his eye movements were recorded by corneal photography. The 1-month-olds fixated away from the faces most of the time, and they looked at their mothers even less often than at the strangers. When they did fixate a face, they usually chose a limited portion of the perimeter. By constrast, 2-month-olds fixated the faces most of the time, looked at more features, and were more likely to look at internal features, especially the eyes. This scanning resembles that reported previously for 2-dimensional shapes, although in some respects it appears unique to faces. 相似文献

Academic self-concept is positively related to individual achievement but negatively related to class- or school-average achievement: the big-fish–little-pond effect (BFLPE). This contrast effect results from social comparison processes. The BFLPE is known to be long-lasting, universal and robust. However, there is little evidence regarding its generalisability across genders. Females, as opposed to males, feel more attached to their peers and compare themselves more often. Thus, it was hypothesised that the BFLPE is larger for females. This was investigated with a focus on science self-concept in a German sample from an extension of the Programme for International Student Assessment 2006 study (N?=?35,015) using recent advances in multilevel modelling. Replicating previous findings, females reported lower self-concepts while controlling for achievement. Additionally, the BFLPE was replicated. However, its effect size was substantially larger for females (?.41) compared to males (?.30). The implications of the results are discussed in light of women’s persisting underrepresentation in science, technology, engineering and mathematics fields. 相似文献

This study tracked the long-term effect of perceptual individuation training on reducing 5-year-old Chinese children's (N = 95, Mage = 5.64 years) implicit pro-Asian/anti-Black racial bias. Initial training to individuate other-race Black faces, followed by supplementary training occurring 1 week later, resulted in a long-term reduction of pro-Asian/anti-Black bias (70 days). In contrast, training Chinese children to recognize White or Asian faces had no effect on pro-Asian/anti-Black bias. Theoretically, the finding that individuation training can have a long-term effect on reducing implicit racial bias in preschoolers suggests that a developmentally early causal linkage between perceptual and social processing of faces is not a transitory phenomenon. Practically, the data point to an effective intervention method for reducing implicit racism in young children. 相似文献

Play-solicitation and social investigatory behaviors were observed in male and female juvenile rats exposed to playful and nonplayful juvenile social stimuli. A nonplayful state was induced by treatment with scopolamine HBr. In Experiment 1, the play-solicitation behavior of males exposed to nonplayful stimuli was reliably greater than that of females; social investigation did not differ by gender. In Experiment 2, males and females were exposed to nonplayful male and female stimuli. Male subjects engaged in more soliciting than did female subjects, and male social stimuli were subjected to more soliciting than were female social stimuli. Experiment 3 compared the influence of varying social deprivation intervals on play soliciting by male juveniles. Although social investigation did not vary reliably with interval of social deprivation, play soliciting increased reliably with longer intervals of isolation. In Experiment 4, play-soliciting behavior of males exposed to nonplayful males correlated positively and reliably with play fighting behavior upon exposure to normally playful males. The results support the proposal that some specific behaviors functionally provoke interactive play fighting. 相似文献

This study discusses the generalizability of gender differences in the second language competences of European adolescents across three languages, three skills and fourteen countries. In most cases, females do better than males but the effect sizes are small or medium at best (Cohen's ds < −0.46). However, English appears rather gender-neutral on average, with males sometimes outperforming females. We also found evidence for cross-skill variation: writing turns out to be more prone to gender differences than listening or reading. Thirdly, we found cross-country variation in the gender gap, which supports the hypothesis that gender is primarily a social factor rather than a biological factor in learning. Multilevel mediation analyses with constituents of motivation indeed show that in most cases where females outperform males, up to 60% of this advantage can be explained by the differential appeal of the students' L2 course and by the instrumental, integrative and intrinsic value that students attribute to the L2. 相似文献

Value-based decisions often involve comparisons between benefits and costs that must be retrieved from memory. To investigate the development of value-based decisions, 9- to 10-year olds (N = 30), 11- to 12-year olds (N = 30), and young adults (N = 30) first learned to associate gain and loss magnitudes with symbols. In a subsequent decision task, participants rapidly evaluated objects that consisted of combinations of these symbols. All age groups achieved high decision performance and were sensitive to gain–loss magnitudes, suggesting that required core cognitive abilities are developed early. A cognitive-modeling analysis of performance revealed that children were less efficient in object evaluation (drift rate) and had longer nondecision times than adults. Developmental differences, which emerged particularly for objects of high positive net value, were linked to mnemonic and numerical abilities. 相似文献

Manual skills slowly develop throughout infancy and have been shown to create clear views of objects that provide better support for visually sustained attention, recognition, memory, and learning. These clear views may coincide with the development of manual skills, or that social scaffolding supports clear viewing experiences like those generated by toddlers during active object exploration. This study used a head-mounted eye tracker to record 5- to 24-month-olds’ object views during repeated mother-infant play sessions (Ns = 18). Results show an early beginning of scaffolding in which parents generate views similar to those of older infants and toddlers, resulting in increased fixations to objects. The finding implicates parents as early scaffolders of object attention and learning. 相似文献

Combined with emotional expressions, eye gaze can provide essential information to indicate threat in the environment. The current study assessed the effects of eye gaze direction on infants’ neural processing of fearful and angry faces. Event‐related potentials were recorded from thirteen 7‐month‐old infants. Two face‐sensitive posterior components, the N290 and P400, as well as a frontocentral negative component (Nc), indicating attentional arousal, were sensitive to eye gaze direction and emotion. A larger Nc was observed for angry faces with direct compared to averted eye gaze. Fearful faces elicited a larger N290 than angry faces, whereas angry faces elicited a more prominent P400 regardless of eye gaze direction. The findings are discussed in terms of early social cognitive and neural development. 相似文献
