Researchers on temporal extension have moved from using global measure
s of temporal extension to using domain-specific measures. A reanalysi
s of 1992 data from 98 boys and 103 girls tested whether domain-specif
ic measures of temporal extension were correlated with global measures
of both past and future temporal extension. Moderate correlations sup
port the generalisation of findings from earlier studies, using global
measures, to more recent studies with domain-specific measures.
