Psychology undergraduates can benefit from direct experiences with laboratory procedures of psychological phenomena. However, they are not always available for students within a distance education program. The present study included students from the Spanish National Distance Education University (UNED) that were to take part in a Basic Psychology examination session. They participated in web-sessions on a tip-of-the-tongue (TOT) laboratory procedure. The aim was to study whether their performance at TOT-related items would be differentially improved. Our results support the conclusion that practicing with the TOT application was effective in improving the TOT comprehension among students. Study A showed that the performance level was higher for the TOT-practiced participants relative to the non-practiced ones. Study B showed significant group by item-type interaction. Also, there was a significant effect of group, and item-type. The results are contextualized in the psychological institutions' mainstream effort for Psychology to be viewed as a STEM discipline by students, the political representatives, and the society.
