Data from seven studies involving 849 high school and college students were used to test the recessive X-linked genetic model prediction that the square of the proportion of men who perform accurately on the water-level task is equal to the proportion of women who perform accurately. Goodness-of-fit tests showed that this prediction was confirmed for each sample. A model with a single estimate of gene frequency accounted for all the data when a classification error parameter was incorporated into the X-linked model. In both models the gene frequency parameter was about . 相似文献

Are motor schemata of facial action spontaneously activated upon the processing of evaluative information? In this case, the processing of positive evaluative information should immediately trigger the motor schema of smiling, and the processing of negative information should trigger frowning. This hypothesis was tested in two experiments in which participants were required to respond to positive and negative words by either smiling or frowning. Electromyogram (EMG) activity was recorded over the brow muscle region (corrugator supercilii) and over the cheek muscle region (zygomaticus major) in order to quantify the latency of muscular response as a dependent measure. In Experiment 1 we found that participants were faster at contracting their zygomaticus muscle (which is involved in smiling) when evaluating positive words, and faster at contracting their corrugator muscle (which is involved in frowning) when evaluating negative words. In Experiment 2, participants were required to respond with the contraction of one of the two muscles whenever a word appeared on the computer screen. Again, we found that responses were faster to congruent response valence combinations than to incongruent response valence combinations. These findings support the hypothesis that evaluative processing is directly linked to motor schemata of facial muscles. 相似文献

ABSTRACT Police use-of-force in general, and police use of deadly force in particular, has been at the forefront of national media attention in recent years. Despite this visibility, scholarly attention to the complexities and nuances of the dynamics at play that lead to fatal and non-fatal outcomes for suspects involved in these encounters has been limited. As such, the current study draws from data collected from 2015 to 2018 in the state of Texas to examine the officer-, suspect-, and situational-level correlates and predictors of suspect death resulting from being involved in an officer-involved shooting. Bivariate results suggest that officer race, suspect race, the suspect being armed with a deadly weapon, and the officer responding to a suspicious activity call are significantly associated with suspect death versus being injured in an officer-involved shooting. More rigorous multivariate results reveal that the situational context (i.e., the suspect being armed with a deadly weapon and the incident resulting from a suspicious activity call) is particularly relevant for predicting the lethality of an officer-involved shooting for the suspect. Study limitations and directions for future research are also discussed. 相似文献
