Searching for a target in a salient region should be easier than looking for one in a nonsalient region. However, we previously discovered a contradictory phenomenon in which a local target in a salient structure was more difficult to find than one in the background. The salient structure was constructed of orientation singletons aligned to each other to form a collinear structure. In the present study, we undertake to determine whether such a masking effect was a result of salience competition between a global structure and the local target. In the first 3 experiments, we increased the salience value of the local target with the hope of adding to its competitive advantage and eventually eliminating the masking effect; nevertheless, the masking effect persisted. In an additional 2 experiments, we reduced salience of the global collinear structure by altering the orientation of the background bars and the masking effect still emerged. Our salience manipulations were validated by a controlled condition in which the global structure was grouped noncollinearly. In this case, local target salience increase (e.g., onset) or global distractor salience reduction (e.g., randomized flanking orientations) effectively removed the facilitation effect of the noncollinear structure. Our data suggest that salience competition is unlikely to explain the collinear masking effect, and other mechanisms such as contour integration, border formation, or the crowding effect may be prospective candidates for further investigation.  相似文献

Attention orienting has been found to be influenced by the previous cueing status in a spatial cueing paradigm. The purpose of this study was to determine whether the cue predictive values or the spatial correspondence learning between cues and targets could influence the sequence effect of symbolic cueing. The findings revealed that the predictive values of arrow or word cues do not lead to different sequence effects, but that visually asymmetrical letter cues, which allow spatial correspondence learning between cues and targets, induce stronger sequence effects than visually symmetrical letter cues. In addition, visually symmetrical directional word cues can induce sequence effects. The results suggest that spatial correspondence learning, although not obligatory, is critical for the sequence effects of symbolic cueing. The findings support the feature‐integration hypothesis, rather than the strategic adjustments account.  相似文献

Survey data often contain many variables. Structural equation modeling (SEM) is commonly used in analyzing such data. With typical nonnormally distributed data in practice, a rescaled statistic Trml proposed by Satorra and Bentler was recommended in the literature of SEM. However, Trml has been shown to be problematic when the sample size N is small and/or the number of variables p is large. There does not exist a reliable test statistic for SEM with small N or large p, especially with nonnormally distributed data. Following the principle of Bartlett correction, this article develops empirical corrections to Trml so that the mean of the empirically corrected statistics approximately equals the degrees of freedom of the nominal chi-square distribution. Results show that empirically corrected statistics control type I errors reasonably well even when N is smaller than 2p, where Trml may reject the correct model 100% even for normally distributed data. The application of the empirically corrected statistics is illustrated via a real data example.  相似文献

In this study, we investigated the effects of facial physical attractiveness on perception and expressing habit of smiling and angry expressions. In experiment 1, 20 participants rated 60 photo subjects’ smiling and angry expressions of uncontrolled physical expression configuration. The results showed that for the angry faces, the perceived expression intensity and the expression naturalness in the attractive group were significantly stronger than those in the unattractive group; for the smiling faces, this attractiveness bias was not observed. In experiment 2, using artificial expressions made by an identical expression template, interestingly, the perceived expression intensity and the expression naturalness of the smiling faces in the attractive group were stronger than those in the unattractive group, while the impression strength of anger between the two groups was approximately the same. A comparison of the two observations suggests that facial physical attractiveness can enhance the perceived intensity of a smiling expression but not an angry expression, and that the inconsistencies between the two experiments are due to the difference of expressing habits between unattractive and attractive persons. These results have implications as regards the effect of facial attractiveness on the expressing habits of expression senders and the person’s development of social skills.  相似文献

Meaning‐focused coping is an important coping strategy in the face of stressful life events. The “construal level theory” and recent research suggest that reflecting on a stressful situation from a self‐distanced stance (temporal or spatial) allows individuals to find meaning in negative life events; however, its long‐term effects have not yet been explored. The present research had two main goals: (1) to determine whether distanced meaning making enhances meaning in life and (2) to explore the underlying emotional mechanism of this effect. We hypothesized that positive affect (relative to negative affect) may play a more important role in the relationship between self‐distanced meaning making and meaning in life. A total of 136 university students were recruited as participants in two studies. The participants were prospectively instructed to make meaning of a highly stressful event. They were randomly assigned to one of three conditions: (a) self‐immersed, (b) temporally distanced, or (c) spatially distanced. The findings indicate that both the temporally and spatially distanced perspectives in the meaning‐making process can enhance meaning in life and that they do so by promoting positive affect. Implications for future research on meaning‐focused coping and self‐distancing are discussed.  相似文献

Objective: Stressful life events (SLEs) impact the quality of life (QOL) of cancer patients. This study investigated the mediation of the relationship between SLEs and QOL (Model 1: Emotional-EQOL and Model 2: Physical/Functional-PFQOL by three types of coping: Action/Planning, Support/Advise-Seeking, and Disengagement/Denial). Design and Main Measures: 662 persons with cancer completed a Stressful Life Events Checklist, the Brief COPE scale, the FACT Emotional, Physical, and Functional Scales, and the Physical Impact Scale of the Sickness Impact Profile. Results: SLEs were positively associated with Action/Planning (Model 1: B?=?0.195, 95% CI = [0.089, 0.304]; Model 2: B?=?0.192, 95% CI = [0.086, 0.289]) and Disengagement/Denial (Model 1: B?=?0.394, 95% CI = [0.281, 0.513]; Model 2: B = .392, 95% CI = [0.285, 0.508]) but not Support/Advice-Seeking; however, only Disengagement/Denial was related to Emotional-QOL (Model 1: B = ?0.659, 95% CI = [?0.848, ?0.498]) and Physical/Functional-QOL (Model 2: B = ?1.460, 95% CI = [?1.856, ?1.069]). Thus, only Disengagement/Denial mediated the relationship between SLEs and QOL. Conclusions: The results indicated that SLEs represent a class of events for which there may be only one dominant coping response, disengagement. SLEs may not be controllable or predictable and reduce capacity for active coping with serious illness. However, SLEs may be detected at any point in the cancer trajectory so that supportive services might be provided.  相似文献
