We examined phonological priming in illiterate adults, using a cross-modal picture-word interference task. Participants named pictures while hearing distractor words at different Stimulus Onset Asynchronies (SOAs). Ex-illiterates and university students were also tested. We specifically assessed the ability of the three populations to use fine-grained, phonemic units in phonological encoding of spoken words. In the phoneme-related condition, auditory words shared only the first phoneme with the target name. All participants named pictures faster with phoneme-related word distractors than with unrelated word distractors. The results thus show that phonemic representations intervene in phonological output processes independently of literacy. However, the phonemic priming effect was observed at a later SOA in illiterates compared to both ex-illiterates and university students. This may be attributed to differences in speed of picture identification.  相似文献

Abstract - In two studies, a newly devised test (framed-line test) was used to examine the hypothesis that individuals engaging in Asian cultures are more capable of incorporating contextual information and those engaging in North American cultures are more capable of ignoring contextual information. On each trial, participants were presented with a square frame, within which was printed a vertical line. Participants were then shown another square frame of the same or different size and asked to draw a line that was identical to the first line in either absolute length ( absolute task ) or proportion to the height of the surrounding frame ( relative task ). The results supported the hypothesis: Whereas Japanese were more accurate in the relative task, Americans were more accurate in the absolute task. Moreover, when engaging in another culture, individuals tended to show the cognitive characteristic common in the host culture.  相似文献

The hypothesis that awareness of phonemic segments influences the way in which speech is perceived was examined. Illiterate adults, who generally lack awareness of segments, were compared with literates, who are aware of the segmental structure of speech, on the recognition of words presented dichotically. A group of people who learned to read and write but who do it only occasionally was also tested. The results indicated much better performance in literates than in illiterates or semiliterates. In addition, literates made proportionally more single-segment errors, especially those limited to the first consonant, and fewer global errors, i.e. on all the segments of a syllable, than illiterates. On the other hand, phonetic feature blendings were as frequent in illiterates as in literates. It is suggested that awareness of segments allows attention to be focused on the phonemic constituents of speech and thus contributes to better recognition in difficult listening conditions. However, awareness of segments does not influence the preattentive extraction of phonetic information.

操作前瞻记忆任务的重要性的方式有两种,研究发现相对重要性会造成进行中任务的损耗,而绝对重要性的研究较少且结果不尽一致,这种差异可能与进行中任务占用认知资源的情况有关。我们使用绝对重要性的指导语来操纵前瞻记忆任务的重要性高或者低,并且以Stroop任务作为进行中任务,来考察绝对重要性和认知资源占用的交互影响。结果发现,在进行中任务一致条件下,绝对重要性的增高促进了进行中任务的完成;而不一致条件下,则会阻碍进行中任务的完成。这说明,进行中任务的认知资源变化与前瞻记忆任务重要性对进行中任务的影响有着交互调节作用。  相似文献

ABSTRACT

Research has shown that observers often spontaneously extract a mean representation from multiple faces/objects in a scene even when this is not required by the task. This phenomenon, now known as ensemble coding, has so far mainly been based on data from Western populations. This study compared East Asian and Western participants in an implicit ensemble-coding task, where the explicit task was to judge whether a test face was present in a briefly exposed set of faces. Although both groups showed a tendency to mistake an average of the presented faces as target, thus confirming the universality of ensemble coding, East Asian participants displayed a higher averaging tendency relative to the Westerners. To further examine how a cultural default can be adapted to global or local processing demand, our second experiment tested the effects of priming global or local processing orientation on ensemble coding via a Navon task procedure. Results revealed a reduced tendency for ensemble coding following the priming of local processing orientation. Together, these results suggest that culture can influence the proneness to ensemble coding, and the default cultural mode is malleable to a temporary processing demand.  相似文献

People from Asian cultures are more influenced by context in their visual processing than people from Western cultures. In this study, we examined how these cultural differences in context processing affect how people interpret facial emotions. We found that younger Koreans were more influenced than younger Americans by emotional background pictures when rating the emotion of a central face, especially those younger Koreans with low self-rated stress. In contrast, among older adults, neither Koreans nor Americans showed significant influences of context in their face emotion ratings. These findings suggest that cultural differences in reliance on context to interpret others' emotions depend on perceptual integration processes that decline with age, leading to fewer cultural differences in perception among older adults than among younger adults. Furthermore, when asked to recall the background pictures, younger participants recalled more negative pictures than positive pictures, whereas older participants recalled similar numbers of positive and negative pictures. These age differences in the valence of memory were consistent across culture.  相似文献

Creative labour has an effect on children's and adults' ownership decisions in Western cultures. We investigated whether preschoolers and adults from an Eastern culture (Japan) would show a similar bias. In a first‐party task (Experiment 1), in which participants created their own objects, Japanese preschoolers but not adults assigned ownership to creators. When participants watched videos of third‐party conflicts between owners of materials and creators (Experiment 2), Japanese adults, but not preschoolers, transferred ownership to creators. In a British comparison group, both preschoolers and adults showed an effect of creative labour in the third‐party task. A bias to attribute ownership on the basis of creative labour is thus not specific to Western culture.  相似文献

The present research examined directional scanning effects (DSE) as a function of reading habit strength among right handers. A picture array naming and recall task was administered to three groups of child readers--unidirectional right-to-left readers of Arabic, unidirectional left-to-right readers of Kannada, and bidirectional readers of Urdu and English--and one group of Urdu illiterate adults. The results showed a right-to-left DSE in the Arabic and Urdu readers. In the latter group the strength of the scanning effect decreased with greater schooling in English. No R-L effect was observed in the Kannada readers or in the Urdu illiterates. These results extend prior research in documenting an "invasion" of culturally acquired reading scan habits onto a nonlinguistic domain. It is suggested that directional scanning effects be controlled or else directly examined in future laterality research involving nonlinguistic stimuli.  相似文献

To what extent do infants represent the absolute pitches of complex auditory stimuli? Two experiments with 8-month-old infants examined the use of absolute and relative pitch cues in a tone-sequence statistical learning task. The results suggest that, given unsegmented stimuli that do not conform to the rules of musical composition, infants are more likely to track patterns of absolute pitches than of relative pitches. A 3rd experiment tested adults with or without musical training on the same statistical learning tasks used in the infant experiments. Unlike the infants, adult listeners relied primarily on relative pitch cues. These results suggest a shift from an initial focus on absolute pitch to the eventual dominance of relative pitch, which, it is argued, is more useful for both music and speech processing.  相似文献

Individuals differ in their orientation toward aspects of the environment. Previous work suggests that some individuals orient primarily toward people, whereas others orient toward things. Women generally orient towards people more than men, and men orient towards things more than women. Person-thing orientation is related to occupational choices. This research examined the structure of person-thing orientation using a combination of exploratory and confirmatory factor analyses and structural equation modeling. Analyses suggested that thing orientation and person orientation can be measured (1) with a few items; (2) separately from each other; and (3) person orientation and thing orientation are not necessarily bipolar opposites.  相似文献

The present study investigates the role of dispositional need for closure (NFC) in how individuals within a particular culture perceive and appreciate choice. Data sets from the US (283 adults), Europe (263 adults and 427 students), China (218 adults and 309 students) and Singapore (258 students) were collected. The results showed that in Western cultures, people perceived choice in a linear way as either a burden or a blessing, whereas in Chinese culture, such opposition between perspectives did not appear, and individuals generally saw choice as both burden and blessing simultaneously. In Western cultures, high dispositional NFC was strongly associated with viewing choice‐as‐a‐burden, whereas Chinese respondents with a high NFC perceived choice as a blessing and a burden simultaneously. The Singaporean results were similar to the Western pattern. These findings are discussed in terms of the NFC literature and cultural differences in dialectic versus differentiation thinking styles.  相似文献

Across cultures, people converge in some behaviors and diverge in others. As little is known about the accuracy of judgments across cultures outside of the domain of emotion recognition, the present study investigated the influence of culture in another area: the social categorization of men's sexual orientations. Participants from nations varying in their acceptance of homosexuality (United States, Japan, and Spain) categorized the faces of men from all three cultures significantly better than chance guessing. Moreover, categorizations of individual faces were significantly correlated among the three groups of perceivers. Americans were significantly faster and more accurate than the Japanese and Spanish perceivers. Categorization strategies (i.e., response bias) also varied such that perceivers from cultures less accepting of homosexuality were more likely to categorize targets as straight. Male sexual orientation therefore appears to be legible across cultures.  相似文献

This study examined the social organization of Guatemalan Mayan fathers' engagement with school-age children in a group problem-solving task. Twenty-nine groups of Mayan fathers varying in extent of Western schooling and 3 related school-age children (ages 6-12 years) constructed a puzzle together. Groups with fathers with 0 to 3 grades more often constructed the puzzle through shared multiparty collaboration involving a common agenda, whereas groups with fathers with 12 or more grades more often structured their contributions through a division of labor. Groups involving fathers with 6 to 9 grades demonstrated patterns of coordination that fell between the other two types of schooling groups. Fathers with greater schooling were also found to propose more explicit division-of-labor plans to children than were fathers with no to little schooling. The results indicate that Western schooling may be gradually transforming the collaborative social organization of group problem solving of indigenous Mayan families.  相似文献

The acquisition of reading has an extensive impact on the developing brain and leads to enhanced abilities in phonological processing and visual letter perception. Could this expertise also extend to early visual abilities outside the reading domain? Here we studied the performance of illiterate, ex‐illiterate and literate adults closely matched in age, socioeconomic and cultural characteristics, on a contour integration task known to depend on early visual processing. Stimuli consisted of a closed egg‐shaped contour made of disconnected Gabor patches, within a background of randomly oriented Gabor stimuli. Subjects had to decide whether the egg was pointing left or right. Difficulty was varied by jittering the orientation of the Gabor patches forming the contour. Contour integration performance was lower in illiterates than in both ex‐illiterate and literate controls. We argue that this difference in contour perception must reflect a genuine difference in visual function. According to this view, the intensive perceptual training that accompanies reading acquisition also improves early visual abilities, suggesting that the impact of literacy on the visual system is more widespread than originally proposed.  相似文献

在中国传统的道德取向中,既有皮亚杰、科尔伯格的“道德公正”,也有吉利根、诺丁斯的“道德关怀”,但是,这两种道德取向在中国社会是以“差序格局”的样态运作的,即以“差序公正”和“差序关怀”的形式存在于中国人的道德判断中。“差序公正”和“差序关怀”的概念准确地表征了中国人道德取向的集体偏见。随着改革的不断深入,各项制度的不断建立和完善,人们的现代化层次不断提高,这种集体偏见正在逐渐得到克服和纠正。  相似文献

Normal variation in temporal orientation has been examined in community dwelling, healthy older subjects but not in elderly hospital patients. We examined the validity of errors in different aspects of temporal orientation as a guide to the presence or absence of cognitive impairment orientation in elderly hospital patients in 150 consecutive patients on the day after admission to an acute geriatric unit. Cognitive impairment (delirium or dementia or both) was diagnosed without reference to temporal orientation. Optimum cutoffs for error scores on the different aspects of temporal orientation (date/year/month/day of the week/time of day) were calculated to maximize the sum of sensitivity and specificity for detection of cognitive impairment. Of the 150 patients, 45 (30%) had cognitive impairment. The best cutoffs for detection of cognitive impairment were an error of more than 3 days in the date; any error in the year, month, or day of the week; and an error of more than 1 h in identifying the time of day. Error in identifying the year had the highest positive likelihood ratio (6.4 [95% confidence interval 4.0–10.3]) for detecting cognitive impairment and the lowest negative likelihood ratio (0.1 [0.04–0.3]) for the exclusion of cognitive impairment. Failure to identify the year correctly is the aspect of temporal orientation most closely related to cognitive impairment.  相似文献

Cognitive behaviour therapy (CBT) in its current form might not be applicable in non Western cultures. Differences between Western and non Western cultures have been reported widely. Psychotherapy was developed in the West and is underpinned by many beliefs which might be specific only to the Western culture. However, in order to modify CBT, we need to understand whether the concepts associated with the CBT might cause conflicts among people who receive therapy. This study explored the beliefs of the university students in Pakistan to find out if the concepts underpinning CBT are consistent with the personal, family, socio-cultural and religious values of the university students. Discussions were held with University students in Rahim Yar Khan, Pakistan. Students were given information on various aspects of the CBT and were asked to rate their agreement with these concepts on a visual analogue scale. There was little disagreement for the principles of CBT for personal values, while some disagreement existed for religious values. This study highlights the value of assessing peoples’ beliefs about acceptability of CBT in non Western cultures. Students in Pakistan felt that the principles of CBT are consistent with their belief system in most areas. However, the value system of students might not be representative of the rest of the population.  相似文献

Poor decision making during adolescence occurs most frequently when situations are emotionally charged. However, relatively few studies have measured the development of cognitive control in response to emotional stimuli in this population. This study used both affective (emotional faces) and non-affective (letter) stimuli in two different flanker tasks to assess the ability to ignore task-irrelevant but distracting information, in 25 adults and 25 adolescents. On the non-emotional (letter) flanker task, the presence of incongruent flanking letters increased the number of errors, and also slowed participants’ ability to identify a central letter. Adolescents committed more errors than adults, but there were no age-related differences for the reaction time interference effect in the letter condition. Post-hoc testing revealed that age-related differences on the task were driven by the younger adolescents (11-14 years); adults and older adolescents (15-17 years) were equally accurate in the letter condition. In contrast, on the emotional face flanker task, not only were adolescents less accurate than adults but they were also more distracted by task-irrelevant fearful faces as evidenced by greater reaction time interference effects. Our findings suggest that the ability to self-regulate in adolescents, as evidenced by the ability to suppress irrelevant information on a flanker task, is more difficult when stimuli are affective in nature. The ability to ignore irrelevant flankers appears to mature earlier for non-affective stimuli than for affective stimuli.  相似文献
