This study examined psychometric properties of the Tempe Sorting Task (TST), a new measure of executive function (EF) for children. To increase the meaningfulness of test score interpretations, an age-appropriate construct was employed to incorporate Denckla's description of EF. Multiple measures of EF, including the TST, were collected for…

The Mini-Mental State Examination (MMSE) is one of the most commonly used instruments to screen for cognitive deficits within the hospital setting.

Examined whether less experienced judges could also produce accurate estimates of the validity of cognitive tests. Shows that the estimates of less experienced judges contain less information than those of experts, but also that average of estimates of several less experienced judges are as accurate as those obtained from small-sample empirical…

Lafferty's Life Styles Inventory was completed by 556 managers (Level I, Self-Description) and by 2,922 peers, subordinates, and supervisors (Level II, Description by Others).
