Today I made a post at IM-HOME discussing the neural efficiency = general intelligence hypothesis (Arthur Jensen) where I make the case that recent research suggests that temporal or timing g (the internal brain clock) is a more fundamental cause of neural efficiency than the dominant Jensen reaction time g hypothesis. Check it out.

What would be the correlation between measures of quickness and measures of timing? Migt an aggregation of both types of measures predict g better than either type alone. I Would be critical of a theoretical position claiming only one type of explanation for interindividual differences in psychometric g.

Good question. I checked the original article and they don't report the temporal g and reaction time g correlations...not sure why. However, communality analysis suggested they shared 10.5% of the explanation of psychometric g. But, when multiple regression was run, temporal g accounted for 31 % of the psychometric g variance and after it was entered in the model first (since it had the highest correlation with psychometric g), reaction time g only added 2% more explanation
