Current theories on autobiographical memory and recent neurological evidence suggest that emotional and non-emotional features of a memory may be retrieved by separate systems. To test this notion, 207 participants who had experienced the break-up of a significant romantic relationship in the last 12 months completed a Multidimensional Scaling (MDS) procedure in relation to the previous relationship. The resulting MDS model revealed two dimensions: a valence and an emotional/non-emotional dimension. Further, participants who associated a high level of distress with their relationship break-up perceived less dissimilarity between emotional and non-emotional features than participants who associated a low level of distress with their relationship break-up. Theoretical and methodological implications for stress and memory are discussed. 相似文献

Mareschal, French, and Quinn (2000) and Mareschal, Quinn, and French (2002) have proposed a connectionist model of visual categorization in 3- to 4-month-old infants that simulates and predicts previously unexplained behavioural effects such as the asymmetric categorization effect (French, Mareschal, Mermillod, & Quinn, 2004). In the current paper, we show that the model's ability to simulate the asymmetry depends on the correlational structure of the stimuli. These results are important given that adults (Anderson & Fincham, 1996) as well as infants (Younger & Cohen, 1986) are able to rely on correlation information to perform visual categorization. At a behavioural level, the current paper suggests that pure bottom-up processes, based on the correlational structure of the categories, could explain the disappearance of the asymmetry in older 10-month-old infants (Furrer & Younger, 2005). Moreover, our results also raise new challenges for visual categorization models that attempt to simulate the shift from asymmetric categorization in 3- to 4-month-old to symmetric categorization in 10-month-old infants (Shultz & Cohen, 2004; Westermann & Mareschal, 2004, 2012). 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

ABSTRACTIn ultra-rapid categorization studies, population-level reaction time differences in performance are consistently reported. In a previous study, we replicated these findings and also observed consistent gender differences in young adults (18–24 years old). We now tested a group of adolescents (11–16 years old) on the same ultra-rapid categorization tasks. Results indicated that age had a significant impact on categorization performance. Although women outperformed men during adulthood, this effect reversed in adolescence (boys faster than girls). This gender x age interaction for categorizing meaningful (non-)social visual scenes could be caused by gender-specific development processes underlying emotion regulation strategies and/or context sensitivity. 相似文献

Attention can select perceptual objects, but it is less clear whether attention can operate on objects defined by higher level cognition, such as semantic associations. Recent studies have shown that attention may be based on objects defined by Chinese two-character compound words, suggesting that attention can operate on semantic objects. In the present study, object-based attention (OBA) effect was investigated at the level of individual Chinese characters, and the role of character structure and radical order in OBA was explored by using a spatial cueing paradigm. In Experiment 1, we found OBA effect for conditions that had legal radical order, but not for other conditions in which the radical order information was disrupted. Character structure, however, had no influence on the OBA effect. In Experiment 2, we observed OBA effect for all conditions after enhancing the radical order and character structure information by adding perceptual cues. The results extend previous findings of a “semantic object”-based attention effect from the two-character word level to the individual character level. Moreover, we found that radical order but not character structure was important for this semantic OBA effect. We conclude that visual attention can be based on semantic objects at the level of individual characters, and that the development of semantic objects is affected by the perceptual grouping of the radicals. 相似文献

ABSTRACT The purpose of this study was to determine the effectiveness of semantic cues provided at encoding and during retention for older adults' memory. For the California Verbal Learning Test-II, participants received semantic or nonsemantic cues that were varied across groups at encoding and during the retention interval. Provision of a semantic cue at encoding led to greater semantic clustering at learning, but not increased recall performance. Providing a semantic cue during the retention interval led to better delayed free recall and greater semantic clustering. No group differences in recall or semantic clustering were found at delayed cued recall. The current findings suggest that semantic cues can be beneficial for recalling unstructured information when administered during the retention interval. 相似文献

The purpose of this study was to assess developmental and social determinants of the age at which children become aware that the social environment can be marked by categorization into religious groups and that those groups are associated with different religious beliefs. The results show that middle childhood is a critical period for this religious social categorization. Moreover, social factors play a role in the development. Religious categorization is likely to appear sooner in children attending heterogeneous schools than in those at homogeneous schools, and children from the minority religious group in the country understand religious categorization earlier than children from the majority group. However, no relation was found between the age at which religious categorization was understood and parents’ religious socialization practices. This study is of both theoretical and practical interest: It complements what is already known about gender, race, and ethnic categorization by integrating developmental and social frameworks, and it can serve as a guideline for educational programs. 相似文献

Recent research has shown that coherence judgements of semantically related word triads are facilitated by a subtle positive response triggered by their increased fluency of processing. Such positive affective response serves as a cue indicating semantic coherence. However, we argue that the fluency of processing is not the only source of affective response that can influence intuitive judgements. The present study investigated differential influences of mood and affective valence of solution words on intuitive coherence judgements. We show that affective cues resulting from processing fluency can be strengthened or weakened by inducing positive or negative affective response through the activation of solutions to semantically coherent triads. Also, mood is shown to impact the breadth of activated associations therefore affecting not only judgements of semantic coherence but also solvability of word triads. We discuss the implications of our findings for how people might form intuitive judgements of semantic coherence. 相似文献

How do people think about social status? We investigated the nature of social status and number representations using a semantic distance latency test. In Study 1, 21 college students compared words connoting different social status as well as numbers, which served as a control task. Participants were faster at comparing occupations and numbers that were semantically farther apart relative to those more closely related. In Study 2, we examined the semantic distance effect for a social status category, for which participants have as much knowledge of, as with numbers. We asked 15 US Navy Midshipmen to compare the social status associated with different ranks in the Navy as well as compare number magnitudes. Participants were fastest when comparing ranks far in status relative to ranks close in status. These findings reveal that humans have mental representations of social status that share properties with that of number. 相似文献

An experiment was conducted to examine whether perceptual information, specifically the shape of objects, is activated during semantic processing. Subjects judged whether a target word was related to a prime word. Prime-target pairs that were not associated, but whose referents had similar shapes (e.g. LADDER-RAILROAD) yielded longer "no" responses than unassociated prime-target pairs, suggesting that shape information had been activated. A visual-field manipulation showed that, in right-handed subjects, this effect was localized in the left hemisphere. This finding is consistent with behavioral, brain imaging, and lesion data, which suggest that object shape at the category level is represented in the left hemisphere. 相似文献
