Evolutionary Theory and the Ultimate–Proximate Distinction in the Human Behavioral Sciences [PDF]

open access: yesPerspectives on Psychological Science, 2011
To properly understand behavior, we must obtain both ultimate and proximate explanations. Put briefly, ultimate explanations are concerned with why a behavior exists, and proximate explanations are concerned with how it works. These two types of explanation are complementary and the distinction is critical to evolutionary explanation.

Editorial: Proximate and ultimate approaches to behavior in a changing world

open access: yesFrontiers in Ecology and Evolution, 2022
[Extract] Tinbergen's (1963) classic four questions for the study of animal behavior have been applied across a range of study species and contexts and provide a solid foundation for understanding species' responses to rapid environmental change. Tinbergen's (1963) proximate questions include understanding the mechanisms (causation) and development ...

Ultimate Strain and Anisotropic Behavior in Corrugated Composites

open access: yesJournal of Advanced Materials in Engineering, 2014
In some applications such as morphing technology, high strain and anisotropic behavior are considered a good advantage. The corrugated composite sheets due to their special geometries have a potential of high deflection under axial loading.

Experimental Investigations on Ultimate Behavior of Fabricated Mobile Scaffolds

open access: yesMetals, 2021
A fabricated mobile scaffold has various components, including vertical members, horizontal members, braces, work plates, and castor wheels. In Korea, the structural performance of each member must be validated based on member-level structural safety ...
