One-hundred-and-twenty-eight patients with unilateral hemispheric damage (53 aphasics, 26 nonaphasic left, and 49 right brain-damaged patients) and 25 normal controls were given a test of symbolic gesture comprehension and other tests of verbal comprehension and of reproduction of symbolic gestures. On the test of symbolic gesture interpretation aphasic patients performed significantly worse than any other group of brain-damaged patients. Within the aphasic patients the inability to understand the meaning of symbolic gestures was highly related to the number of semantic errors obtained at a verbal comprehension test. On the contrary, only a mild relationship was found between comprehension and reproduction of symbolic gestures. Some implications of these findings are discussed. 相似文献
A dominant theory of embodied aesthetic experience (Freedberg & Gallese, 2007, Trends in Cognitive Sciences, 11, 197) posits that the appreciation of visual art is linked to the artist’s movements when creating the artwork, yet a direct link between the kinematics of drawing actions and the aesthetics of drawing outcomes has not been experimentally demonstrated. Across four experiments, we measured aesthetic responses of students from arts and non-arts backgrounds to drawing movements generated from computational models of human writing. Experiment 1 demonstrated that human-like drawing movements with bell-shaped velocity profiles (Sigma Lognormal [SL] and Minimum Jerk [MJ]) are perceived as more natural and pleasant than movements with a uniform profile, and in both Experiments 1 and 2 movements that were perceived as more natural were also preferred. Experiment 3 showed that this effect persists if lower-level dynamic stimulus features are fully matched across experimental and control conditions. Furthermore, aesthetic preference for human-like movements were associated with greater perceptual fluency in Experiment 3, evidenced by unbiased estimations of the duration of natural movements. In Experiment 4, line drawings with visual features consistent with the dynamics of natural, human-like movements were preferred, but only by art students. Our findings directly link the aesthetics of human action to the visual aesthetics of drawings, but highlight the importance of incorporating artistic expertise into embodied accounts of aesthetic experience. 相似文献
When people judge height from the top looking down they tend to overestimate vertical distance. Initial findings suggest that this perceptual bias may be in part due to the experienced fear of falling. However, previous studies did not control for potentially relevant optical invariants, especially vertical texture gradient cues, that may inform such perceptual judgments. In this study, we examined to what degree texture gradient cues may account for the perceptual bias in height perception. To this end, in 2 different conditions in which vertical texture gradient cues were either present or absent, participants provided distance and size judgments from an elevated position (5.68 m) and from the ground. Results revealed a systematic overestimation of vertical extent and object size when judged from a height. Yet, the absence or presence of texture gradient cues did not differentially influence these judgments. Finally, although fear levels were reported to be larger at the elevated position than on the ground, fear levels did not correlate with the perceptual bias, thereby demanding further research into the mechanisms underlying the perceptual bias in height perception. 相似文献
The present longitudinal study examined the role of quality of friendship in mediating the relation of pro‐sociality to self‐esteem over time. Participants were 424 Italian young adults (56% females) assessed at two waves (Mage = 21.1 at Time 1; Mage = 25 at Time 2). An autoregressive cross‐lagged panel model was used to test the mediational model. Self‐ and friend‐report measures of pro‐sociality, quality of friendship, and self‐esteem were included in the analyses. Results were in line with the hypothesized paths, with quality of friendship mediating the relation of pro‐sociality to later self‐esteem above and beyond its high stability. Self‐esteem, in turn, predicted pro‐sociality 4 years later. Overall, the present findings support the potential benefits of behaving pro‐socially for an actor in terms of increased perceived self‐worth and also expand previous work by outlining the specific mediational role of the quality of friendships. The theoretical and practical implications of these results are discussed. 相似文献
Objective: The purpose of this study was to examine the longitudinal relationship between Positivity (POS), defined as a stable disposition to view at experience under a positive outlook, and physical and psychological functioning in a sample of cancer patients immediately after diagnosis and one year later.
Methods: A total of 110 patients (40% males) with pulmonary, colorectal and breast cancer, aged 30–75 (M age = 59.62; SD = 10.33), have been prospectively enrolled between 2012 and 2013, at the S. Andrea Hospital in Rome. All patients were previously aware of their diagnosis. A follow-up one year after diagnosis was conducted. We used structural equation modeling in order to analyse the specific effects of POS on functioning impairment from diagnosis to follow up.
Results: POS was associated with less functioning impairment both at diagnosis and follow-up assessments. Furthermore, POS level at diagnosis continued to be associated with less functioning impairment one year later, after controlling for its stability.
Conclusions: Patients with higher level of POS tended to report less symptoms associated with negative affect such as anxiety and despondency and to preserve their habitual relationships and social roles. POS may act as a basic disposition that sustains patients’ efforts to deal efficaciously with severe illness, by complying with medical treatment and using cognitive strategies that enable individuals to cope with concurrent and prospective challenges of illness. 相似文献
We investigated age and gender effects on “Positive Orientation” (POS)—an individual's tendency to view life with a positive outlook—using a genetically informed design. Study subjects were 1016 twins aged 22–75 from the Italian twin registry. We assessed POS by the recently developed P‐scale. First, we used confirmatory factor analysis to investigate scale's measurement invariance by age and gender. Then, we applied biometric modelling to estimate genetic and environmental components of POS score. Overall, we found a satisfactory degree of measurement invariance by both age and gender. Results from these analyses further indicated an increasing mean level of POS across the lifespan. Additive genetic and unshared environmental factors explained respectively 58% and 42% of variance in POS score, with no significant gender differences; furthermore, the pattern of change of gene‐environment architecture of POS over time was consistent with a greater plasticity of personality at older ages. 相似文献
This study evaluates the temporal structure of daily self-esteem and the relative contribution of a range of theoretically motivated predictors of daily self-esteem. To assess self-esteem stability, a daily version of the Rosenberg Self-Esteem scale (RSE, Rosenberg, 1965) was administered to 278 undergraduates for five consecutive days. These short-term longitudinal data were analysed using the Trait State Error (TSE) modelling framework. The TSE decomposes multi-wave data into three components: (1) a stable trait component, (2) a state component, and (3) an error component. Significant predictors of the trait component of self-esteem observed across five days were: (1) emotional stability, and (2) the congruence between implicit and explicit self-esteem. Significant predictors of the state components of self-esteem were daily positive and negative events. We discuss the implications of these results for future research concerning self-esteem stability. 相似文献
