The aim of our paper is to introduce generalized neighborhood bases and gn - T(2)-spaces. (psi, psi')-continuity, sequentially (psi, psi')-continuity and psi-convergency are investigated on strong generalized first countable spaces, and also two results about psi-convergency on gn - T(2)-spaces are given.
