In 1976 I published a book titled, The Inner Athlete dealing with Sport Psychology (Nideffer, 1976a), and an article in the Journal of Personality and Social Psychology (Nideffer, 1976b) on the development of a psychological test called The Attentional and Interpersonal Style (TAIS) Inventory. The Inner Athlete dealt with the role concentration plays in performance and presented a set of theore...

Experience is one of the most commonly studied variables in clinical judgment research. In a meta-analysis of research from 1970 to 1996 of judgments made by 4,607 participants from 74 studies, Spengler, White, Ægisdóttir, Maugherman, Anderson, et al. (2009) found an experience-accuracy fixed effect of d = .121 (95% CI [.06, .18]), indicating that with more experience, counseling and other psyc...

Exposure to high lead concentrations produces severe alterations in central nervous system development and, consequently, in the behavior of both experimental animals and children (l-5). However, in asymptomatic children exposed to lead intoxication the resulting intellectual and behavioral abnormalities may be expressed in different waysi.e., as hyperactivity (S), fine motor incoordination (7)...

Education, a long neglected variable affecting psychological test score, is in search of reemphasis. Some evidence for this has accumulated on the psychological tests constructed and standardized here at the department of Psychiatry, P.G.I., Chandigarh. Tentative norms prepared education wise on WAIS-Verbal section, PGI-Memory Scale, Proverb and Similarity Tests, Psychoticism Questionnaire, and...

There has been insufficient effort in most areas of applied psychology to evaluate incremental validity. To further this kind of validity research, the authors examined applicable research designs, including those to assess the incremental validity of test instruments, of test-informed clinical inferences, and of newly developed measures. The authors also considered key statistical and measurem...

The timing relation between a motor action and the sensory consequences of that action can be adapted by exposing participants to artificially delayed feedback (temporal recalibration). Here, we demonstrate that a sensorimotor synchronization task (i.e., tapping the index finger in synchrony with a pacing signal) can be used as a measure of temporal recalibration. Participants were first expose...
