Several theoretical conceptions emphasize the importance of prompt response
s to infant's signals in providing them with early causal,experiences. The
present paper examines if a maternal tendency toward prompt responses can b
e identified by distributional analyses of maternal response latencies and:
if this response tendency can be shown for different communicative channels
(in verbal/vocal, nonverbal,: intermodal communication). In addition, the
paper focuses on the relation between the temporal contingency of maternal
behavior and measures of maternal interactional quality. Interactional sequ
ences of 54 mother and 3-month-old infant dyads were analyzed using microan
alytical assessment techniques and ratings of interactional quality. Distri
butional analyses of maternal expressions during face-to-face encounters re
vealed that promptness of responses toward infant signals with a short late
ncy is a typical response tendency in maternal behavior. There are, however
, individual differences between mothers, indicating that this response ten
dency is expressed in different communicative channels by individual mother
s. This is shown by low correlations between the contingency indices of dif
ferent communicative channels. The relation between contingency and rated i
ndicators of interactional quality turned out to be rather small, indicatin
g that maternal contingency may be conceptualized to contribute an independ
ent factor to the quality of maternal interactional behavior.
