Table A2.

Interactions between post-verbal constituent order and phonological overlap on speech rate by sentence region.

Effect	Theme-last			Theme-last: subject-verb			Theme-last: verb-theme			Theme-last: subject-verb: verb-theme
Region	$\widehat{\beta }$	t	p	$\widehat{\beta }$	t	p	$\widehat{\beta }$	t	p	$\widehat{\beta }$	t	p
Pre-subject	−0.01	−0.1		−0.02	−0.8		−0.04	−1.5		0.04	0.7
Pre-verb	−0.01	−0.5		0.01	0.2		0.03	1.4		0.02	0.5
Pre-theme	0.22	12.2	<0.0001	0.01	0.1		−0.01	−0.5		−0.04	−0.6
Pre-recipient	0.20	9.9	<0.0001	0.01	0.1		−0.04	−1.3		0.09	1.3

The only significant effects were found for the pre-theme and pre-recipient region. For both regions, speech rates were higher for the theme-last order, paralleling the effect found for fluency in the pre-recipient region (i.e., fewer disfluencies in the theme-last order). Bold indicates the significant effects.
