Two algorithms are provided which define two new ways of averaging waveforms. The representative average maintains shape, has average d.c. offset, average amplitude and average position of noise-free input signals whose onset varies in time after a trigger pulse. The synchronous average removes random bipolar noise, the amplitude of which is below a critical threshhold, from a randomly occuring waveform. The latter does not require a trigger pulse, maintains its shape, has an average d.c. offset and average amplitude. Its position in the output field is such that the centroid of the waveform is placed in the center of the field. Both methods involve the definition of average phase angle and a quantity called the angular standard deviation. 相似文献

This study addresses three issues: (a) Which attributes characterize children's friendship choices? (b) Which show sex differences? (c) Which dimensions of teacher ratings of behavior contribute to peer selections? The issue of peer-teacher relatedness is addressed by obtaining peer nominations for certain attributes and independent measures of behavior that have been shown to be related to peer popularity. The results demonstrate that: (a) Peer acceptance is indexed by “Like to Sit By,” and this pattern is generally similar for boys and girls, with the exception of the dimension “Good at Games,” which characterizes boys' choosing peers. (b) The data on peer acceptance and rejection do not result in simple, bipolar dimensions, since these are not highly negatively correlated. (c) When peer nominations are assessed for possible teacher influences, an interesting sex difference emerges: girls prefer not to sit next to children whom their teachers rate as high in behavior problems. 相似文献

This study provides evidence regarding the controversy about the relationship of socioeconomic status (SES) and ethnicity to self-concept. Subjects were 345 first-, second-, and third-grade children of low SES (180 were black) attending inner city schools in a large metropolitan area. The Purdue Self Concept Scale was the measure of self-concept. There was a decline in self-concept with grade level (p < .01), and blacks scored higher than whites (p < .01). An analysis of black second-grade children's scores indicated that the race difference was due to the high scores of those with welfare status. Low expectations resulting from SES and ethnic segregation, effects of the black pride movement, and defensiveness are considered as possible explantions. 相似文献
