The cognitive approach began to revolutionize psychology in the late 1950âs and early 1960âs, to become the dominant approach (i.e. perspective) in psychology by the late 1970s. Interest in mental processes had been gradually restored through the work of Piaget and Tolman.
poâ¢rosâ¢iâ¢ty. 1. the state or quality of being porous. 2. (in rock or other natural material) the ratio of aggregated pore space to the volume of the entire mass: used as a measure of the amount of fluid, as oil, that a geologic stratum might hold. [1350â1400; Middle English porosytee porÅsitÄs. See porous, -ity ].
Nonporous Defined. Nonporous simply describes something that is not permeable to air, water or other fluids. If a surface such as a countertop is nonporous, it simply cannot contain any air or water within it. Pores are minute openings or crevices that allow air and water to flow to and fro; nonporous surfaces do just the opposite.
