    Notes: [Auszug] The mathematics involved in solving this problem for automatic exchanges were first developed by Erlang (Brockmeyer, Halstrom and Jensen)1. Subsequent extensions2 provide a basis for calculating subscriber delay, given the traffic-level, the number of operators available to deal with it, and the ...

    Notes: [Auszug] Thirty subjects listened to 8-digit numbers which had been recorded on tape at rates either of 30 or 90 digits per minute. Immediately at the end of each number, a timing device was started which clicked loudly at one of two rates, again either 30 or 90 per minute. Subjects wrote down the 8-digit ...

    Notes: [Auszug] Only two sets of such data have hitherto been published. One3 is based on the King James version of the Bible, and the other4 on an unspecified source. As the source may be an important variable, we have analysed two samples of modern English. The first represents written language and comprises all ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] One possible method of studying change in the memory trace is to observe whether recall errors show any systematic tendency. Errors consistently associated with specific stimuli might then be regarded as representing the state of a partially decayed trace. Sequences containing 6 letters of the ...

    Notes: [Auszug] Using a 10-key keyboard, subjects (18 postmen aged 30-40 years) were taught a logical association between pairs of keys and letters of the alphabet, except Q. The nature of the association is irrelevant here; but one might note that instruction required four 45-min sessions spread over two days, to ...

    Notes: [Auszug] I have, however, shown4 that for the case of visually presented letter sequences this assumption is false. If an item is forgotten: (1) the alternative items are not equi-probable responses, and (2) the probability of their occurrence can be predicted by reference to a confusion matrix of 1 ...
