In two experiments, subjects were required to match printed names with subsequently displayed achromatic shades or geoinetric shapes. The presence of incongruent shades or shapes at the time of word display substantially slowed the RT for performing the match. This pictorial interference (interference due to a visual, nonlingalistic attributel was substantially attenuated, however, as the delay between the word display and shapes or shades to be matched was increased beyond 100 msec. These findings illnstrate the occurrence of a transitory automatic pathway activation from an irrelevant pictorial attribute, which may be contrasted with the verbal interference effects typically observed in Stroop-naming tasks. In both our tasks and the Stroop task, selectiwe attention fails when a stimulus must be transformed to another form of encoding in the presence of a competing stimulns which is already close to that form. 相似文献

Growing evidence suggests that the underlying geometry of a visual image is an effective mechanism for conveying the affective meaning of a scene or object. Indeed, even very simple context-free geometric shapes have been shown to signal emotion. Specifically, downward-pointing V??s are perceived as threatening and curvilinear forms are perceived as pleasant. As these shapes are thought to be primitive cues for decoding emotion, we sought to assess whether they are evaluated as affective even without extended cognitive processing. Using an Implicit Association Test to examine associations between three shapes (downward- and upward-pointing triangles, circles) and pleasant, unpleasant, and neutral scenes, in two studies we found that participants were faster to categorize downward-pointing triangles as unpleasant compared to neutral or pleasant. These findings were specific to downward-pointing shapes containing an acute angle. The present findings support the hypothesis that simple geometric forms convey emotion and that this perception does not require explicit judgment. 相似文献

It has been suggested that downward pointing triangles convey negative valence, perhaps because they mimic an underlying primitive feature present in negative facial expressions (Larson, Aronoff, and Stearns, 2007). Here, we test this proposition using a flanker interference paradigm in which participants indicated the valence of a central face target, presented between two adjacent distracters. Experiment 1 showed that, compared with face flankers, downward pointing triangles had little influence on responses to face targets. However, in Experiment 2, when attentional competition was increased between target and flankers, downward pointing triangles slowed responses to positively valenced face targets, and speeded them to negatively valenced targets, consistent with valence-based flanker compatibility effects. These findings provide converging evidence that simple geometric shapes may convey emotional valence. 相似文献

Inferring category attributes from exemplar attributes: geometric shapes and social categories 总被引:1,自引:0,他引:1
Three experiments tested the hypothesis that judgments about the attributes of categories are disproportionately based on the characteristics of exemplars that best fit the category. In the first 2 experiments, subjects were presented with good and bad exemplars of categories with defining attributes (rectangles, triangles, pentagons, and ellipses) in which different colors were arbitrarily paired with the good and poor examples. In both experiments, subjects erroneously judged the colors paired with the good exemplars as more frequent than colors paired with the poor exemplars. A third experiment, using social categories, examined whether attributes associated with a single category member were more likely to generalize to the category as a whole for prototypical than for nonprototypical category members. Subjects were presented with information about individual fraternity members who varied in prototypicality, and the tendency to infer a target behavior (liberal vs. conservative voting behavior) from the individual fraternity member to the fraternity as a whole increased with the prototypicality of the category member. Implications for the contact hypothesis, category-exemplar relations, and belief stability are discussed. 相似文献

Previous work has proposed that simple geometric shapes, carrying the features present within negative or threatening faces are especially effective at capturing or guiding attention. Here we test this account and provide converging evidence for a threat-based attentional advantage. Experiment 1 found that downward-pointing triangles continue to be detected more efficiently than upward-pointing triangles when: (i) both overall RT and search slope measures are obtained; and (ii) when the set size is varied and the stimuli are presented in random configurations. Experiment 2 tested and ruled out an alternative account of the selection advantage, based on differences between triangle shape consistencies with scene perspective cues. Overall, the data provide converging evidence that simple geometric shapes, which might be particularly important in providing emotional signals in faces, can also attract attention preferentially even when presented outside of a face context. 相似文献

Repeated one-millisecond exposures to random polygon targets have been shown to result in preference for the target shapes over similar distractor shapes in the absence of recognition (Knust-Wilson & Zajonc, 1980). Seamon, Brody, and Kauff (1983a) interpreted this preference-without-recognition effect in terms of a two-process model of recognition memory. The present set of experiments tested three predictions of the two-process model: Target discrimination equal to that found in the preference task should also occur when subjects make familiarity judgments; recognition performance should improve if the target stimuli are presented and tested with an easily encodable visual context; and both preference and familiarity judgments should be unaffected by manipulations of context. The results supported all three predictions. The implications of the results for a competing model proposed by Zajonc (1980) are also discussed. 相似文献

To examine the hypothesis that there is a metaphoric link between geometric shapes (square vs. circle) and moral traits (integrity vs. deviousness), we conducted three experiments in China. In Study 1, integrity-related words were classified faster when embedded in a square than in a circle. Conversely, deviousness-related words were classified faster in a circle than in a square. Study 2 found that a person who preferred squares was perceived as more righteous and that a person who preferred circles was perceived as more devious. Study 3 revealed that the participants were more likely to pair a square with integrity-related words and a circle with deviousness-related words in a memory task. Given the negation of square-integrity and circle-deviousness emotional congruence, the findings of this research show that shape-related information is a meaningful part of the mental representations of moral traits. 相似文献

In five experiments, we examined the influence of contextual objects’ location and visual features on visual memory. Participants’
visual memory was tested with a change detection task in which they had to judge whether the orientation (Experiments 1A,
1B, and 2) or color (Experiments 3A and 3B) of a target object was the same. Furthermore, contextual objects’ locations and
visual features were manipulated in the test image. The results showed that change detection performance was better when contextual
objects’ locations remained the same from study to test, demonstrating that the original spatial configuration is important
for subsequent visual memory retrieval. The results further showed that changes to contextual objects’ orientation, but not
color, reduced orientation change detection performance; and changes to contextual objects’ color, but not orientation, impaired
color change detection performance. Therefore, contextual objects’ visual features are capable of affecting visual memory.
However, selective attention plays an influential role in modulating such effects. 相似文献

To assess the differential salience of geometric features embedded in spatial displays, 60 preschool children, 3 to 5 years old, were required to reconstruct a series of geometric displays. Each arrangement included the depiction of a topological feature, unconnectedness; a Euclidean feature, linearity; and a projective feature, orientation. Children built their reconstructions under two demand conditions. The reconstructions were scored for the number that preserved each of the different geometric features. Results from a mixed-design analysis of variance revealed main effects for age, demand condition, and geometric feature, as well as for several first-order interactions. Data indicated that the Euclidean feature was the most salient and most frequently preserved characteristic and that the topological and projective ones were more problematic. The findings were discussed as a contrast to Piagetian predictions. 相似文献

When a shape is alternately presented in two positions differing in both location and orientation, apparent motion tends to be experienced over a curved path. The curvature provides evidence about principles of object motion that may have been internalized in the perceptual system. This study introduces a technique for estimating deviation from a straight path. A shape was alternately presented on the two sides of a visual partition with a "window" just wide enough to accommodate the shape. Observers adjusted the location of the window to maximize the illusion of smooth passage of the shape through the window. In accordance with theoretical expectations, estimated deviations from rectilinear motion increased with the separation between the stimuli in spatial location, angular orientation, and time. 相似文献

Olfactory experiences represent a domain that is particularly rich in crossmodal associations. Whereas associations between odors and tastes, or other properties of their typical sources such as color or temperature, can be straightforwardly explained by associative learning, other matchings are much harder to explain in these terms, yet surprisingly are shared across individuals: The majority of people, for instance, associate certain odors and auditory features, such as pitch (Belkin, Martin, Kemp, & Gilbert, Psychological Science 8:340–342, 1997; Crisinel & Spence, Chemical Senses 37:151–158, 2012b) or geometrical shapes (Hanson-Vaux, Crisinel, & Spence, Chemical Senses 38:161–166, 2013; Seo, Arshamian, et al., Neuroscience Letters 478:175–178, 2010). If certain odors might indeed have been encountered while listening to certain pieces of music or seeing certain geometrical shapes, these encounters are very unlikely to have been statistically more relevant than others; for this reason, associative learning from regular exposure is ruled out, and thus alternative explanations in terms of metaphorical mappings are usually defended. Here we argue that these associations are not primarily conceptual or linguistic, but are grounded in structural perceptual or neurological determinants. These cases of crossmodal correspondences established between contingent environmental features can be explained as amodal, indirect, and transitive mappings across modalities. Surprising associations between odors and contingent sensory features can be investigated as genuine cases of crossmodal correspondences, akin to other widespread cases of functional correspondences that hold, for instance, between auditory and visual features, and can help reveal the structural determinants weighing on the acquisition of these crossmodal associations. 相似文献

The Kripkean metaphysical modality (i.e. possibility and necessity) is one of the most important concepts in contemporary
analytic philosophy and is the basis of many metaphysical speculations. These metaphysical speculations frequently commit
to entities that do not belong to this physical universe, such as merely possible entities, abstract entities, mental entities
or qualities not realizable by the physical, which seems to contradict naturalism or physicalism. This paper proposes a naturalistic
interpretation of the Kripkean modality, as a naturalist’s response to these metaphysical speculations. It will show that
naturalism can accommodate the Kripkean metaphysical modality. In particular, it will show that naturalism can help to resolve
the puzzles surrounding Kripke’s a posteriori necessary propositions and a priori contingent propositions.
