Let X,X1,X2,… be i.i.d. nondegenerate random variables, Sn=∑nj=1Xj and V2n=∑nj=1X2j. We investigate the asymptotic \vspace*{1pt} behavior in distribution of the maximum of self-normalized sums, max1≤k≤nSk/Vk, and the law of the iterated logarithm for self-normalized sums, Sn/Vn, when X belongs to the domain of attraction of the normal law. In this context, we establish a Darling--Erdős-type theorem as well as an Erdős--Feller--Kolmogorov--Petrovski-type test for self-normalized sums.
