Weather front areas of precipitation help determine the frontal type and location. There are two different meanings used within meteorology to describe weather around a frontal zone. The term "anafront" describes boundaries which show instability, meaning air rises rapidly along and over the boundary to cause significant weather changes. A "katafront" is weaker, bringing smaller changes in temperature and moisture, as well as limited rainfall. A cold front is located at the leading edge of the temperature drop off, which in an isotherm analysis shows up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface
Methods used to study memory G.E. Müller who continued the tradition of lists of items to conduct memory experiments on human subjects and using behavioral data to develop models of memory. The two most common types of memory studied using these methods are recognition and recall. Recognition memory is the ability to judge whether or not the cued item was previously presented on the list usually with a yes or no response. This memory is akin to the type of memory used for police line-ups. The particular task described used to be called "item recognition". Scientists study the rates of hits (correct "yes" responses) related
