Children learn what words mean from hearing words used across a variety of contexts. Understanding how different contextual distributions relate to the words young children say is critical because context robustly affects basic learning and memory processes. This study examined children's everyday experiences using naturalistic video recordings to…

Reading in difficult or novel fonts results in slower and less efficient reading (Slattery & Rayner, 2010); however, these fonts may also lead to better learning and memory (Diemand-Yauman, Oppenheimer, & Vaughan, 2011). This effect is consistent with a desirable difficulty effect such that more effort during encoding results in better…

Learners in the trades are faced with learning a large amount of technical vocabulary along with the content of their field, but they do not tend to encounter this language outside their courses of study. This technical vocabulary is a core element in their developing knowledge of their trade and their learner identity. This article focuses first…

Classic accounts of lexical organization posit that humans are sensitive to environmental frequency, suggesting a mechanism for word learning based on repetition. However, a recent spate of evidence has revealed that it is not simply frequency but the diversity and distinctiveness of contexts in which a word occurs that drives lexical…

Seventy-four high school seniors participated in a study that examined the construct validity of vocabulary tests and the nature of verbal ability by integrating findings and theories of cognitive psychology with those of differential psychology. The subjects completed three kinds of measurement instruments: (1) an experimental faceted vocabulary…

In three immediately succeeding trials, 45 young adults named 50 pictures of objects as rapidly as possible; word retrieval latencies were measured for each item. Before each trial, one experimental group was given information as to the word frequency (WF) level of the items' names. The other experimental group was given information as to the…
