associativity

(programming)

The property of an operator that says whether a sequence of three or more expressions combined by the operator will be evaluated from left to right (left associative) or right to left (right associative). For example, in Perl, the lazy and operator && is left associative so in the expression:

$i >= 0 && $x[$i] >= 0 && $y[$x[$i]] == 0

the left-most && is evaluated first, whereas = is right associative, so in

$a = $b = 42

the right-most assignment is performed first.

Although not definitive evidence against the associative assumption (see Gawronski & Bodenhausen, 2006), it does serve to highlight that alternative, nonassociative accounts may also be worth exploring.

As outlined above, this null result can be explained if it is accepted that a positive occasion-setting function of the 24-hr deprivation cues in this group was counteracted by nonassociative effects of these cues.

An alternate explanation for these general increases may be due to a nonassociative, long term effect of testosterone in both the paired and home cage testosterone-exposed animals, perhaps via an attentional mechanism.

Aside from their obvious connection to the theories of Brauer groups and module categories over monoidal categories [19], it seems also reasonable to expect that such division algebras would have similar applications in quantum (specifically, nonassociative) geometry and physics as their classical analogue quaternions, octonions and generalizations do, see e.g.
