Aging affects verb fluency task performance, with older adults showing higher initial motor content. This motor content decreases in the oldest group, independent of other factors, highlighting semantic parameter importance for frontostriatal impairment.
Area of Science:
- Neuropsychology
- Cognitive Aging
- Neurology
Context:
- Verb fluency tests assess frontostriatal integrity.
- Aging alters brain physiology and morphology.
- Impact on semantic aspects of verb fluency is not well understood.
Purpose:
- To investigate how aging influences sequential motor content and lexical frequency in verb fluency tasks.
- To analyze verb production, motor content, and lexical frequency across different age groups.
Summary:
- Eighty-six participants aged 51-70 were divided into four groups.
- Verb fluency production was analyzed in 15-second intervals.
- Older adults initially produced verbs with higher motor content, which decreased in the 66-70 group.
Impact:
- This study provides novel insights into motor content during verb fluency in older Mexican Spanish speakers.
- Results suggest the importance of evaluating semantic parameters in verb fluency for clinical practice.
- Further research is needed to generalize findings to broader populations.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
