Apparently, the process of resource allocation fails to explain why electrodermal underarousal was
beneficial for children’s attention performance in the couple conflict group but not in the control
group. Interpretation in the light of the behavioral inhibition system (BIS) of the two-factor learning
theory by Gray (1975) might be helpful for this purpose.
Conversely, heightened BIS activity, which is characterized by passive and fearful behavioral tendencies (Beauchaine, 2001), needs to be considered as highly dysfunctional in this context.
