For example, following a segment with an anterior place of articulation, a posterior segment's place of articulation is pulled frontward, and listeners' category ... perceptually attune or compensate for coarticulatory context. An alternative is that shifts result from spectral contrast. Indeed, shifts occur when speech precursors are replaced ...

The serial shift of digit identity toward posterior confirms a mechanistic possibility that was previously inferred from the evolutionary ... 4. Experimental homeotic transformations of single digits are well-documented, but frame-shifts of more than one digit are not. We investigated the pattern of cartilage formation in ...
