14 Sources of Variation within the Individual
نویسندگان
چکیده
This chapter reviews sources of variation in decision making and choice that arise within the individual, and discusses the possible signifi cance of such variation for the development of an evolutionarily plausible account of decision making. Different sources of within-individual variation are reviewed, including noise, general cognitive ability and life span changes, mood, and personality. The approaches taken by economics, cognitive psychology, and the psychology of personality and individual differences are compared to and contrasted with ecological and evolutionary approaches. It is argued that sampling models may provide a unifi ed cognitive approach to withinand between-individual variation in human judgment and decision making, albeit one that has yet to be linked suffi ciently to ecological and evolutionary approaches.

ABSTRACTRenewable Energy Sources (RES) are well – defined as energy sources, that are in abundance within the natural surroundings and are much inexhaustible. In addition, hydroelectricity (HE) is a vital part of world renewable energy supply and hydropower remains a bulk source of electricity generation because of its environmental friendliness in nature. Modeling is the analysis of the ...
متن کاملPopulation and life-history consequences of within-cohort individual variation.
The consequences of within-cohort (i.e., among-individual) variation for population dynamics are poorly understood, in particular for the case where life history is density dependent. We develop a physiologically structured population model that incorporates individual variation among and within cohorts and allows us to explore the intertwined relationship between individual life history and po...

Sources of individual variation in plasma testosterone levels
The steroid hormone testosterone (T) plays a central role in the regulation of breeding in males, because many physiological, morphological and behavioural traits related to reproduction are T dependent. Moreover, in many seasonally breeding vertebrates, male plasma T levels typically show a pronounced peak during the breeding season. While such population-level patterns are fairly well worked ...
متن کاملGenetic variation of Garra rufa fish in Kermanshah and Bushehr provinces, Iran, using SSR microsatellite markers
Six highly variable microsatellite loci were used to investigate the genetic diversity and population structure of the Garra rufa in Kermanshah and Bushehr provinces, Iran. All of the 6 microsatellite loci screened in this study showed polymorphism. A total of 90 individual fish from 3 populations were genotyped and 60 alleles were observed in all loci. The number of alleles per locus ranged fr...
