In simultaneous learning two verbal lists are interlaced for study, with each tested separately. In the present experiments simultaneous learning was used as a means of determining the conditions under which study time or learning resources might be reallocated between lists. One of the lists was called the standard list and remained constant…

It sometimes happens that one is unable to recall a word or name that he feels he knows very well. This state of frustrated recall is referred to as a tip-of-the-tongue (TOT) experience. Two experiments were devised to compare the ability of a weak trace and a decoding-failure model to predict the conditions under which TOT reports would be most…

The frequent description of this tip-of-the-tongue (TOT) phenomenon as subthreshold memory traces is challenged by data showing that TOT genesis and TOT recovery are distinct processes. In a verbal…
