In addition, the multisensory units of the caudate nucleus and substantia nigra showed significant cross-modal interaction, displaying additive or superadditive response facilitation to multisensory simulation.
One of the popular aggregation operator fuzzy integrals is the Choquet integral which is introduced by Choquet [90], Choquet integral is defined as a subadditive or superadditive to integrate functions with respect to the fuzzy measures [91].

(ii) if [mu] (B [union] Q) [greater than or equal to] p(B) + [mu](Q), the fuzzy measure is said to be superadditive, which means there is a positive synergetic interaction between B and Q (or we say they are complementary);
If, in addition, U : [L.sub.2e]([iR.sub.0+]; [C.sup.n]) [right arrow] [L.sub.2e]([iR.sub.0+]; [C.sup.n]) is strictly accretive with constant k, odd superadditive, and bounded of norm [k.sub.U] < 1/2 then it is incrementally strictly positive with [k.sub.1] = k(1 - 2[k.sub.U]) and also incrementally strictly passive if the operator is self-adjoint.
Otherwise, it may happen that uncontrolled, parallel associative processes are intervening on the statement that backward association is the main responsible on false memory variability (e.g., high FAS in high BAS lists, superadditive effects of FAS and BAS, etc.).

In a multi-national context, there is often--and certainly in the climate change case--a superadditive aspect to the possible joint actions by the countries, in the sense that together they can (i) do more than the sum of their alternative individualistic policies, and (ii) generate a larger joint benefit than the sum of their benefits when acting individualistically.
(H2) there exist a nonnegative mapping g : I [right arrow] [R.sub.+], function [LAMBDA] : I x [l.sub.1] [right arrow] R and a superadditive mapping [phi] : [R.sub.+] [right arrow] [R.sub.+], i.e., [phi](s) + [phi](t) [less than or equal to] [phi](s + t) for s, t [greater than or equal to] 0, such that
Complex problems and systems are either sub- or superadditive and therefore they are difficult to model and describe at a single level of analysis.
For any A,B [subset or equal to] N, A [intersection] B = [empty set], if v(A [union] B) [greater than or equal to] v(A) + v(B), then v is called superadditive game.
* Superadditive risk specific to individual consumers: Superadditive risk arises when the joint distribution of consumer risk differs materially from the aggregated product-specific distributions of risks.
