Fig 1.
Example of map task materials.
The instruction giver’s map, with a route leading from “Start” (top left) to “Ziel” (finish; bottom left), is in the left panel. Mismatches between maps are highlighted with red circles.
Fig 2.
Example excerpt of a GAT transcription.
Two turn transitions (following newly introduced landmarks) are highlighted in bold (lines 15/16; 21/22).
Fig 3.
Categories and measurement of turn transitions.
“Gaps” are silent intervals between turn transitions; “between-overlaps” are turn transitions composed of overlapping speech from both interlocutors. Gaps are represented with positive Floor Transfer Offset (FTO) values (see right arrow for an FTO value of about +600 ms); overlaps are represented with negative FTO values (see left arrow for an FTO value of about -600 ms).
Fig 4.
Floor Transfer Offset (FTO) values by group.
Positive values represent gaps; negative values represent overlaps. ASD group in blue, CTR group in green. The dotted line indicates the value of 0 ms FTO, representing no-gap-no-overlap transitions. Dashed lines indicate the values of +200 ms (expected for typical transitions) and +/-700 ms FTO (unusually long transitions).
Fig 5.
Positive values represent gaps; negative values represent overlaps. ASD group in blue, CTR group in green.
Fig 6.
FTO values by group and dialogue stage.
The black curve represents the beginning of the dialogue (until detection of the first Mismatch); the orange curve represents the remainder of the dialogue (after detection of the first Mismatch). Positive values represent gaps; negative values represent overlaps. ASD group on the left, CTR group on the right.
Fig 7.
FTO values by dialogue stage and dyad.
Positive values represent gaps; negative values represent overlaps. ASD dyads in the top half and outlined in blue, CTR dyads in the bottom half and outlined in green. Black curves represent the beginning of dialogue (before detection of the first Mismatch); orange curves represent the remaining dialogue (after detection of the first Mismatch).
Fig 8.
FTO values by turn transition and group.
Positive values represent gaps; negative values represent overlaps. ASD group in blue, CTR group in green. Thin blue/green lines represent averaged FTO values by transition and group; thick lines represent fitted LOESS-smoothed curves by group, the surrounding grey shaded areas the respective standard error. The dashed vertical lines show 1) transition no. 38 (average time point for detection of first Mismatch) and 2) transition no. 90 (average time point for resolution of first Mismatch).
