Relation of task switching to speed, age, and fluid intelligence
Article Abstract:
Two new studies investigate whether an accurate task-switching model could be identified and to determine if it was related to adult age and measures of higher order cognition. Both studies show that there was moderate correlation of task switching across various combinations of tasks and distinguished between a model reflecting processing speed and a switching construct. The second study shows that age is linked to the task-switching construct and to spatial visualization, episodic memory and inductive reasoning, although they are not independent of other variables.

Shared age-related influences on cognitive and noncognitive variables
Article Abstract:
A new study of previous data investigates the age-related influences on cognitive and noncognitive variables. The results show that measures of blood pressure, grip, strength and visual acuteness, and measures of spatial visualization, speed of perception, episodic memory and inductive reasoning, share age-related variance. However, controlling the age-related influence substantially reduces the variance shared between cognitive and noncognitive variables.

Is there anything special about the aging of source memory?
Article Abstract:
Structural equation modeling was used to evaluate the validity of a source-memory construct and to explore the relation of the source-memory construct to age and to the other cognitive variables. Study revealed that source memory might not have discriminant validity and there were only small unique age-related effects on the source-memory construct after the influence of other abilities were taken into account.
