Same vague expression, different conceptualizations

The study was to investigate the vague words measurement across native and non-native English speakers and gender differences. Ninety-two students from the University of Oklahoma participated in this study by filling out an internet-based questionnaire on the vague words. The researchers put each of the thirty-two vague words in a context, or the same word put into different contexts. The participants were asked to rate the degree or the numerical value that they thought was the most appropriate in the context of the vague word. It was found that ten out of the thirty-two words had a significant difference across the native and non-native English speakers, and two of thirty-two words had a significant difference across genders. The word ＂fairly＂ showed the most significant difference interactions of language speaking by gender.

炎帝神农氏“七曜起于天关”的年代

关于炎帝的历法,宋.罗泌在《路史》中记载：＂三朝具于摄提,七曜起于天关,所谓太初历也。＂这里,＂三朝＂指年月日;＂摄提＂即摄提格,是指地支中的寅,＂七曜＂为日月五星。这说明炎帝创制的《太初历》起始日那天,为寅年寅月寅日,日月五星会聚在一起,并且是从＂天关＂星开始。通过天文年代学的计算和分析,可以确定公元前4 951年3月28日为炎帝《太初历》的起始日。

A behavior systems view of responding to probe stimuli during an interfood clock

Two experiments used a behavior systems approach to relate the form of responses during an interfood clock to the temporal distance of the individual clock stimuli to food. Stimuli proximate to food should better control a focal search mode and related responses, whereas stimuli temporally distant from food should better control a general search mode and related responses. Experiment 1 conditioned two groups of rats with a sequence of four equal-length 12-sec clock stimuli that terminated with food and then tested for the conditioning of a general search mode by presenting an unconditioned moving probe stimulus (either a rolling ball bearing or a rotating mechanical door) during each of the clock stimuli. Consistent with a behavior systems view, contact with the ball bearing was markedly greater during a clock stimulus distant from food. The absence of similar differential contact of the door across the clock stimuli showed that the effect was specific to the ball bearing rather than a general response to stimulus dimensions of movement and sound. Experiment 2 showed that the general search mode was controlled by the clock stimulus rather than the passage of time.
