A supplementary treatment is proposed which helps identify sources of bias affecting groups of test items. This treatment is illustrated with the tranformed item-difficulty method as applied to an evaluation of a test used to help select applicants to be admitted to an aviation training program.

A study was conducted to extend the sequential probability ratio testing (SPRT) procedure with the polytomous model under some practical constraints in computerized classification testing (CCT), such as methods to control item exposure rate, and to study the effects of other variables, including item information algorithms, test difficulties, item…

To demonstrate a relationship between rate of habituation and complexity levels, 11-week-old infants (N=51) were each given a rate-of-habituation and complexity-level test. Rapid habituators looked longer at complex patterns. Irregular habituators responded randomly to tests or resembled slow habituators in terms of complexity preferred. (ST)

Pause detection thresholds and the duration of fluent and hesitation pauses as a function of syntactic complexity were studied in 12 normal young adult male speakers. (KW)

A system of translation using the computer to assist but not replace the translator is described. Each of the system's three levels incorporates successively more sophisticated translation aids, all under the translator's control. The third level incorporates a full machine translator. (MSE)

Demonstrated that six-year-olds performed as well as 17-year-olds in discriminating self-generated memories from memories that were the result of external presentation. However, six-year-olds were not as adept as nine-year-olds in discriminating what they had said earlier from what they had only thought. (Author/MP)
