Previous research suggests that people encode gender starting in childhood. The present research asked whether gender diverse children (i.e., children whose gender identity or expression differs from that expected based on assigned sex) encode gender. Results showed that 3- to 5-year-old gender diverse participants (N = 71), siblings of gender diverse children (N = 52), and gender conforming controls (N = 69) did not significantly differ in degree of gender encoding. These results converge with prior research to suggest that gender diverse children process gender in ways that do not differ from gender conforming children, and provide further evidence that gender encoding may be a common aspect of person perception in societies that support a binary view of gender. 相似文献

ABSTRACT The aims of this study were (a) to describe the kinematics underlying the phenomenon of the knee of the swing leg passing medially in front of the athlete during the single push (SP) phase of the block sprint start, and (b) to determine the relationships between block phase pelvis range of motion (RoM), 1st step width and block phase performance. Three-dimensional kinematic data (250 Hz) were collected from eleven competitive sprinters (100 m PB: 11.17 ± 0.41) performing maximal effort block starts. The joint angles of the rear hip with respect to the pelvis and the pelvis segment angles with respect to the laboratory coordinate system were calculated during the block start phase to the end of the 1st stance. A combination of pelvis list and rotation (not hip adduction) was coupled with the thigh of the swing leg moving medially during the SP phase. A very high positive correlation was found between pelvic list RoM and 1st step width (r = 0.799, p = 0.003). No other significant correlations were found. Attempting to reduce pelvic RoM or changing frontal and transverse plane hip joint angles to minimise medial thigh motion is unlikely to lead to an improvement to performance. 相似文献

This study demonstrates that NVivo, a popular research tool for content analysis, produces biased Cohen’s kappa as it calculates the reliability statistic at the character level, which is unsuitable for most content-analytic studies adopting a higher unit of analysis (e.g., sentence, paragraph). Based on empirical data and a statistical simulation, this study proposes a method of bias correction applicable to situations where two independent raters conduct binary coding. 相似文献
