Many theories of how pretense is mentally represented have been posited, but none have been effectually empirically tested to date. This research is the first to explore how children and adults mentally process simple pretend actions, specifically pretend object substitutions, and whether this representation changes with age. Preschoolers, older children, and undergraduates heard or read about a variety of pretend object substitutions, and their reaction time to name an image related to the object's real identity, pretend identity, or an unrelated image was measured. To test what is unique to pretense, these reaction times were compared to those from participants who responded to the same images after reading about nonpretend versions of the same actions. Results suggest that preschoolers inhibit reality when representing a pretend action, older children activate an object's real and pretend identities equally, and adults activate the object's real identity more than the pretend one. Implications for current theories of pretense representation are discussed. 相似文献

Odor naming is enhanced in communities where communication about odors is a central part of daily life (e.g., wine experts, flavorists, and some hunter‐gatherer groups). In this study, we investigated how expert knowledge and daily experience affect the ability to name odors in a group of experts that has not previously been investigated in this context—Iranian herbalists; also called attars—as well as cooks and laypeople. We assessed naming accuracy and consistency for 16 herb and spice odors, collected judgments of odor perception, and evaluated participants' odor meta‐awareness. Participants' responses were overall more consistent and accurate for more frequent and familiar odors. Moreover, attars were more accurate than both cooks and laypeople at naming odors, although cooks did not perform significantly better than laypeople. Attars' perceptual ratings of odors and their overall odor meta‐awareness suggest they are also more attuned to odors than the other two groups. To conclude, Iranian attars—but not cooks—are better odor namers than laypeople. They also have greater meta‐awareness and differential perceptual responses to odors. These findings further highlight the critical role that expertise and type of experience have on olfactory functions. 相似文献

The practice of a woman assuming her husband's last name upon marriage is a deeply embedded norm in some countries. Whether or not individual heterosexual couples reproduce or resist this practice, it provides a context for making decisions about marital names. No conventions, other than heteronormative ones, govern naming practices in same‐sex relationships and families, but very little is known about name changing in these contexts. This paper reports an exploratory qualitative study of the ways in which 30 lesbians and gay men in committed relationships made meaning of name changing and keeping. Only one participant reported changing her last name, some considered name changing a future possibility, but most had no plans to change their name. The lack of conventions regarding naming in same‐sex families created a dilemma for some participants—who would take whose name? Many participants did not want to entirely give up their name, thus a hyphenated last name was the most popular option for those contemplating a name change. Accounts of name changing centred on doing/being family. This was also a theme in accounts of name keeping, along with maintaining a continuity of personal and professional identity, avoiding hassle, complications and confusion and resisting heteronormativity. The findings are discussed in relation to other research on naming in same‐sex families and research on heterosexual marital naming practices. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

People with grapheme-color synesthesia perceive specific colors when viewing different letters or numbers. Previous studies have suggested that synesthetic color experience can be bistable when induced by an ambiguous character. However, the exact relationship between processes underlying the identity of an alphanumeric character and the experience of the induced synesthetic color has not been examined. In the present study, we explored this by focusing on the temporal relation of inducer identification and color emergence using inducers whose identity could be rendered ambiguous upon rotation of the characters. Specifically, achromatic alphabetic letters (W/M) and digits (6/9) were presented at varying angles to 9 grapheme-color synesthetes. Results showed that grapheme identification and synesthetically perceived grapheme color covary with the orientation of the test stimulus and that synesthetes were slower naming the experienced color than identifying the character, particularly at intermediate angles where ambiguity was greatest. 相似文献

Morphed figures entail a dominant and nondominant interpretation. Testing perception of morphed objects using forced-choice methods demonstrates that morphed figures are perceived as their dominant interpretation (“categorical perception”, or CP). Using a more natural free-naming response could reveal whether CP is an effect independent of method. In Experiment 1, therefore, series of morphed figures were tested for CP using free naming. Half of the morph series were identified as CP patterns. In Experiment 2, we used forced choice to investigate CP, resulting in an increase of number of CP series compared to free naming. The overlap between CP series of Experiments 1 and 2 was small, however. Experiment 3 revealed that higher perceptual similarity between the extremes of the series was strongly related to CP for the free-naming method, in contrast to the forced-choice method. We conclude that the observation of CP depends on the intactness of the intrinsic object structure caused by the morphing procedure. 相似文献

ABSTRACT The impact of age-related changes in visual-perceptual processing on naming ability has not been reported. The present study investigated the effects of 6 levels of spatial frequency and 6 levels of contrast on accuracy and latency to name objects in 14 young and 13 older neurologically normal adults with intact lexical-semantic functioning. Spatial frequency and contrast manipulations were made independently. Consistent with the hypotheses, variations in these two visual parameters impact naming ability in young and older subjects differently. The results from the spatial frequency-manipulations revealed that, in general, young vs. older subjects are faster and more accurate to name. However, this age-related difference is dependent on the spatial frequency on the image; differences were only seen for images presented at low (e.g., 0.25–1 c/deg) or high (e.g., 8–16 c/deg) spatial frequencies. Contrary to predictions, the results from the contrast manipulations revealed that overall older vs. young adults are more accurate to name. Again, however, differences were only seen for images presented at the lower levels of contrast (i.e., 1.25%). Both age groups had shorter latencies on the second exposure of the contrast-manipulated images, but this possible advantage of exposure was not seen for spatial frequency. Category analyses conducted on the data from this study indicate that older vs. young adults exhibit a stronger nonliving-object advantage for naming spatial frequency-manipulated images. Moreover, the findings suggest that bottom-up visual-perceptual variables integrate with top-down category information in different ways. Potential implications on the aging and naming (and recognition) literature are discussed. 相似文献

Previous work has shown that reaction times to find a target in displays that have been repeated are faster than those for displays that have never been seen before. This learning effect, termed “contextual cueing” (CC), has been shown using contexts such as the configuration of the distractors in the display and the background colour. However, it is not clear how these two contexts interact to facilitate search. We investigated this here by comparing the strengths of these two cues when they appeared together. In Experiment 1, participants searched for a target that was cued by both colour and distractor configural cues, compared with when the target was only predicted by configural information. The results showed that the addition of a colour cue did not increase contextual cueing. In Experiment 2, participants searched for a target that was cued by both colour and distractor configuration compared with when the target was only cued by colour. The results showed that adding a predictive configural cue led to a stronger CC benefit. Experiments 3 and 4 tested the disruptive effects of removing either a learned colour cue or a learned configural cue and whether there was cue competition when colour and configural cues were presented together. Removing the configural cue was more disruptive to CC than removing colour, and configural learning was shown to overshadow the learning of colour cues. The data support a configural dominant account of CC, where configural cues act as the stronger cue in comparison to colour when they are presented together. 相似文献

This study investigated whether in speech production object properties flow in a cascaded manner or whether cascaded processing is restricted to the object's identity. In Experiments 1 and 2, participants saw pictured objects and had to state either their size (GRAND or PETIT—meaning big and small) or their name. The size of the objects varied as a function of the way they were presented on the computer screen (Experiment 1) or their real size in the world (Experiment 2). In Experiment 3, faces of young and old men were coloured in yellow or in green. The task was to name either the colour (JAUNE or VERT, meaning yellow and green, respectively) or the age (JEUNE or VIEUX, meaning young and old, respectively) of the face. In Experiments 1 and 2, no reliable effects of phonological relatedness (“GORILLE–grand”—a big gorilla) were found on the object-naming latencies. However, size-naming latencies were shorter when the adjective shared the initial phoneme of the picture name (i.e., “GRAND–gorille”) than when it did not (i.e., “GRAND–dinosaure”—saying “big” in response to a big dinosaur). In Experiment 3, phonological overlap did not affect colour naming latencies, or age naming latencies. Overall, these findings strongly suggest that cascaded processing is restricted to the object's identity in conceptually driven naming tasks. 相似文献
