Consistency of individual differences in several measures of Skinner box operant and other activity and their intercorrelations in 14 chinchilla bred rabbits were studied. Reliability analysis revealed that both operant and activity measures were highly consistent (Cronbach alpha>0.87) over at least 15 days. Furthermore, locomotor activity, the tendencies to press the lever with high frequency,...

This paper examined the reliability and validity of the State-Trait-Cheerfulness-Inventory (STCI) in Mainland China. The Chinese translation of the STCI-T<106i>, STCI-S<45i> and the Temporal Satisfaction with Life Scale (TSWLS) were administered to 476 university students (313 females, 157 males, 6 missing; 20.40 ± 1.35 years of age). Results showed that the STCI-T<106> and the STCI-S<45> had h...

issues in the detection and interpretation of interaction effects between quantitative variables in multiple regression analysis are discussed. Recent articles by Cronbach (1987) and Dunlap and Kemery (1987) suggested the use of two transformations to reduce "problems" of multicollinearity. These transformations are discussed in the context of the conditional nature of multiple regression with ...
