cis-trans isomerism

[′si¦stranz ī′säm·ə‚riz·əm]
(organic chemistry)
A type of geometrical isomerism found in alkenic systems in which it is possible for each of the doubly bonded carbons to carry two different atoms or groups; two similar atoms or groups may be on the same side (cis) or on opposite sides (trans) of a plane bisecting the alkenic carbons and perpendicular to the plane of the alkenic system.

34) had significantly fewer CIS effects than did those who experienced ease of retrieval (M = 1.
29) exhibited stronger CIS effects than did those who selected the lead-acid battery (M = 0.
CIS effects were the indicators of confirmation bias and were determined by subtracting the number of consistent information items from the number of inconsistent information items (Fischer, Kastenmuller et al.
We determined that ease of retrieval (the recall of few reasons) resulted in stronger CIS effects, and difficulty of retrieval (the recall of many reasons) resulted in less tendency to search for confirmatory information.
