In this article, we examine the performance of different eye blink detection algorithms under various constraints. The goal of the present study was to evaluate the performance of an electrooculogram- and camera-based blink detection process in both manually and conditionally automated driving phases. A further comparison between alert and drowsy drivers was performed in order to evaluate the impact of drowsiness on the performance of blink detection algorithms in both driving modes. Data snippets from 14 monotonous manually driven sessions (mean 2 h 46 min) and 16 monotonous conditionally automated driven sessions (mean 2 h 45 min) were used. In addition to comparing two data-sampling frequencies for the electrooculogram measures (50 vs. 25 Hz) and four different signal-processing algorithms for the camera videos, we compared the blink detection performance of 24 reference groups. The analysis of the videos was based on very detailed definitions of eyelid closure events. The correct detection rates for the alert and manual driving phases (maximum 94%) decreased significantly in the drowsy (minus 2% or more) and conditionally automated (minus 9% or more) phases. Blinking behavior is therefore significantly impacted by drowsiness as well as by automated driving, resulting in less accurate blink detection. 相似文献

Humans possess an invaluable ability of self-expression that extends into visual, literary, musical, and many other fields of creation. More than any other profession, artists are in close contact with this subdomain of creativity. Probably one of the most intriguing aspects of creativity is its negative correlation with the availability of monetary reward. The aim of this study was to investigate the reactivity of the dopaminergic reward system in artists and nonartist controls using the desire-reason-dilemma (DRD) paradigm, which allows separate evaluation of reactivity to the acceptance and rejection of rewards. Using fMRI, blood-oxygen-level-dependent (BOLD) responses were measured in key regions of the reward system, namely the ventral striatum (VS), the ventral tegmental area (VTA), and the anterior ventral prefrontal cortex (AVPFC). In contrast to controls, artists presented significantly weaker VS activation in reward acceptance. Additionally, they showed stronger suppression of the VS by the AVPFC in reward rejection. No other differences in demographic or behavioral data were evidenced. These results support the existence of characteristic neural traits in artists, who display reduced reactions to monetary reward acceptance and increased reactions to monetary reward rejection. 相似文献

Greater male variability has been established in cognitive abilities and physical attributes. This study investigated sex differences in variability in vocational interests with two large samples (N > 40 000 and N > 70 000). The results show that although men varied more in Realistic and Enterprising interests, women varied more in Artistic and Conventional interests. These differences in variability had considerable influence on the female–male tail ratios in vocational interests that have been found to contribute to reported gender disparities in certain fields of work and academic disciplines. Moreover, differences in means and variability interacted non‐linearly in shaping tail‐ratio imbalances. An age‐specific analysis additionally revealed that differences in variability diminished with age: Older samples showed smaller differences in variance in Realistic, Artistic, and Social interests than younger samples. Thus, I found no evidence that greater male variability applies for vocational interests in general. Copyright © 2015 European Association of Personality Psychology 相似文献

Country,sex, and parent occupational status: Moderators of the continuity of aggression from childhood to adulthood 下载免费PDF全文

The authors examined the prediction of occupational attainment by age 40 from contextual and personal variables assessed during childhood and adolescence in 2 participant samples: (a) the Columbia County Longitudinal Study, a study of 856 third graders in a semirural county in New York State that began in 1960, and (b) the Jyv?skyl? Longitudinal Study of Personality and Social Development, a study of 369 eight-year-olds in Jyv?skyl?, Finland, that began in 1968. Both samples were followed up during adolescence and early and middle adulthood. Structural modeling analyses revealed that in both countries, for both genders, children's age 8 cognitive-academic functioning and their parents' occupational status had independent positive long-term effects on the children's adult occupational attainment, even after other childhood and adolescent personal variables were controlled for. Further, childhood and adolescent aggressive behavior negatively affected educational status in early adulthood, which in turn predicted lower occupational status in middle adulthood. 相似文献

The present study analyzed whether the tripartite model of well-being (Keyes in J Health Soc Res 43:207–222, 2002; Journal of Consulting and Clinical Psychology 73:539–548, 2005a) and low depression can be captured by a core factor. Furthermore, it examined whether well-being shows continuity from early middle adulthood to middle adulthood. The study was based on the Finnish Jyväskylä Longitudinal Study of Personality and Social Development (Pulkkinen 2006), where the same participants (initial N = 369; 53% males) have been followed from age 8 until middle age. Data gathered at ages 36 and 42 were used. Well-being was indicated by (a) emotional well-being (including positive mood and low negative mood, satisfaction with different life-domains, and happiness); (b) Scales of Psychological Well-Being (Ryff in J Pers Soc Psychol 57:1069–1081, 1989); (c) Scales of Social Well-Being (Keyes in Soc Psychol Q 61:121–140, 1998); and (d) low level of depression. These measures were administered at both ages (except for social well-being, which was available only at age 42). The results, based on structural equation modeling, showed that a latent factor consisting of the above dimensions of well-being fit the data and that the structure of well-being was the same across genders and time. Well-being showed a high continuity from age 36 to 42 (standardized coefficient 0.84). As a conclusion, the different dimensions of well-being had only little variance of their own and a core factor of well-being was empirically established. 相似文献

According to the account by comparative distinctiveness, minorities draw attention by virtue of their relative size, leading to more individuation and more stereotyping of their members. Using the ‘Who said what?’ paradigm by Taylor, Fiske, Etcoff, and Ruderman ( 1978 ) in Klauer and Wegener's ( 1998 ) modified version, relative group size of gender categories and age categories was varied in a pilot study and a main experiment, respectively. In the pilot study, memory for discussion statements and in both studies, memory for individuating information increased as subgroup size decreased. Rating measures obtained in the main experiment revealed most stereotyping of minority members. The findings thereby support major predictions of the account by comparative distinctiveness, but demonstrate dissociations between different modes of category‐based processing, i.e. category memory, reconstructive category use, and stereotyping.
