especially when the task is difficult and when it places few constraints on the content of the …

Factors affecting word retrieval were compared in a timed picture-naming paradigm for 520
drawings of objects. In prior timed and untimed studies by Snodgrass and Vanderwart …

Conversational speech from over 300 speakers from 17 to 68 years of age was analyzed for
age-related changes in the timing and content of spoken language production. Overall …

Introduction The ability to speak is grounded in general memory and control processes and

may vary as a function of different factors. Motivated by findings from neurodegenerative …

The change in confrontational naming ability accompanying normal ageing has been widely
studied. However, inconsistent findings have been reported. Our study reexamined this …

Healthy elderly adults are slower to initiate and produce speech. However, the sources of
the slowing remain poorly understood. The present study evaluates to which extent …

Previous studies have shown both declining and stable semantic-memory abilities during
healthy aging. There is consistent evidence that semantic processes involving controlled …

We compared the performance of young (college-aged) and older (50+ years) speakers in a
single object and a multiple object naming task and assessed their susceptibility to semantic …
