For instance, picture naming has visual object recognition as its lead-in process, followed by a core process consisting of all stages of word production.
We conducted paired-sample t-tests comparing the mean percentages at each age of lead-in labels that were successful either with or without gestures.
The spheres together with the screens should damp out any swirling motions created by the lead-in pumping.
This method requires finding a context that is uniquely associated with the targeted structure, and then using a lead-in statement to elicit the child's production.
Lead-in labels were further coded as ' lead-in-successful ' or 'lead-in-unsuccessful ', based on children's subsequent attention or inattention to the labeled object.
We conclude, as predicted, that the relation between lead-in labels and children's vocabulary development is not necessarily a negative one, as had been previously theorized.
Thus, gesture seems to have a moderating effect on the success of lead-in labels.
Finally, use of gesture is associated with the redirective success of lead-in labels.
