This study investigated memory from interrupted visual searches. Participants conducted a change detection search task on polygons overlaid on scenes. Search was interrupted by various disruptions, including unfilled delay, passive viewing of other scenes, and additional search on new displays. Results showed that performance was unaffected by short intervals of unfilled delay or passive viewing, but it was impaired by additional search tasks. Across delays, memory for the spatial layout of the polygons was retained for future use, but memory for polygon shapes, background scene, and absolute polygon locations was not. The authors suggest that spatial memory aids interrupted visual searches, but the use of this memory is easily disrupted by additional searches. 相似文献

We explored infants’ ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object placed side by side: a correctly colored picture (e.g., red strawberry) and an inappropriately colored picture (e.g., green-blue strawberry). The results showed that, overall, the 6- to 8-month-olds showed preference for the correctly colored pictures for color-specific objects, whereas they did not show preference for the correctly colored pictures for the non-color-specific object. The 5-month-olds showed no significant preference for the correctly colored pictures for all object conditions. These findings imply that the recognition of canonical color for objects emerges at 6 months of age. 相似文献

Most Chinese characters are composed of a semantic radical on the left and a phonetic radical on the right. The semantic radical provides the semantic information; the phonetic radical provides information concerning the pronunciation of the whole character. The pseudo‐characters in the study consisted of different sub‐lexical parts of real Chinese characters and consequently they also had the semantic radical and the phonetic radical. But they were not readable and had no actual meaning. In order to investigate the spatiotemporal cortical activation patterns underlying the orthographic, phonological and semantic processing of Chinese characters, we used event‐related brain potentials (ERPs) to explore the processing of Chinese characters and pseudo‐characters when 14 healthy Chinese college students viewed the characters passively. Results showed that both Chinese characters and pseudo‐characters elicited an evident negative potential peaking around 120 ms (N120), which appeared to reflect initial orthographic distinction and evaluation. Then, Chinese pseudo‐characters elicited a more positive ERP deflection (P220) than did Chinese characters 200–250 ms after onset of the stimuli. It was similar to the recognition potential (RP) and might reflect the integration processes of phonological and semantic processing on the basis of early orthographic information. Dipole source analysis of the difference wave (pseudo‐characters minus characters) indicated that a generator localized in the left temporal‐occipital junction contributed to this effect, which was possibly related to phonological and perceptual–semantic information integration. Between 350–450 ms, a greater negativity (N360) in pseudo‐characters as compared to characters was found over midline fronto‐central scalp regions. Dipole analysis localized the generator of N360 in the right parahippocampal cortex. Therefore, the N360 might be an N400 component and reflect the higher‐level semantic activation on the basis of orthographic, phonological and perceptual–semantic processing. 相似文献

Facial electromyography (EMG) is a useful physiological measure for detecting subtle affective changes in real time. A time
series of EMG data contains bursts of electrical activity that increase in magnitude when the pertinent facial muscles are
activated. Whereas previous methods for detecting EMG activation are often based on deterministic or externally imposed thresholds,
we used regime-switching models to probabilistically classify each individual’s time series into latent “regimes” characterized
by similar error variance and dynamic patterns. We also allowed the association between EMG signals and self-reported affect
ratings to vary between regimes and found that the relationship between these two markers did in fact vary over time. The
potential utility of using regime-switching models to detect activation patterns in EMG data and to summarize the temporal
characteristics of EMG activities is discussed. 相似文献

This essay explores the history of studies in analytical philosophy in China since the beginning of the last century, by dividing
into three phases. It shows that, in these phases, analytic philosophy was always at a disadvantage in confronting serious
challenges coming from both Chinese traditional philosophy and modern philosophical trends. The authors argue that Chinese
philosophers have both done preliminary studies and offered their own analyses of various problems as well as some new applications
of analytic philosophy especially in the latest period. Meanwhile, Chinese traditional philosophy was always trying to adjust
its cultural mentality in the struggle with analytic philosophy, and accommodated in its own way the rationalistic spirit
and scientific method represented in analytic philosophy. 相似文献

Luo Congyan put forward the idea that benevolence is the substance while righteousness is its function, which placed the intrinsic
value of human beings on a more fundamental position and affirmed the unity of benevolent principle and universal norms from
the perspective of the relationship between substance and function. The unity of benevolence and righteousness involves the
connection between value and norms, and the latter relate to the relationship between morality and law in the broader sense.
On the basis of the idea of using both benevolence and righteousness, Luo Congyan examined the relationship between morality
and law. Corresponding to the emphasis on the role of both law and political power, Luo Congyan concerned himself with how
to establish rational interpersonal relationships in various ways. Furthermore, Luo Congyan emphasized the significance of
behavior in everyday life, while he affirmed that the universal principle should be followed. In this way, he developed the
earlier Confucian thought.

The effect of emotion-focused orientation at retrieval on emotional memory in young and older adults
This study examines how emotion-focused orientation at retrieval affects memory for emotional versus neutral images in young and older adults. A total of 44 older adults (ages 61–84 years, M=70.00, SD=5.54) and 43 young adults (ages 17–33 years, M=20.58, SD=3.72) were tested on their free recall and forced-choice recognition of images. At retrieval the emotion-focused orientation was manipulated by instructing participants to focus on emotion-related information (i.e., emotional content of images and the emotional reactions evoked by the images). In the control conditions participants were either instructed to focus on visual information or not provided any specific orientation instruction. In free recall but not forced-choice recognition, the emotion-focused orientation increased young adults’ positivity bias and thus wiped out their superior negativity bias. However, the emotion-focused orientation did not affect older adults’ emotional memory. The data suggest that young adults activate and prioritise emotional goals in response to external demand during intentional information processing whereas older adults seem to spontaneously tune themselves to emotional goals. 相似文献
