European pied flycatcher Ronald Fisher in 1912. The sexy son hypothesis in evolutionary biology and sexual selection, proposed by Patrick J. Weatherhead and Raleigh J. Robertson of Queen's University in Kingston, Ontario in 1979, [1] states that a female's ideal mate choice among potential mates is one whose genes will produce males with the best chance of reproductive success.
The handicap principle is a disputed hypothesis proposed by the Israeli biologist Amotz Zahavi in 1975. It is meant to explain how "signal selection" during mate choice may lead to "honest" or reliable signalling between male and female animals which have an obvious motivation to bluff or deceive each other.
First of all, it is uncertain how the process from conversion to innovation takes place as at the conversion stage, individuals internalize at a private level. Secondly, the stages end after the fourth one: at this point, the normative position of the majority is eliminated as they have revealed their new views publicly.
In cognitive psychology, the affect-as-information hypothesis, or 'approach', is a model of evaluative processing, postulating that affective feelings provide a source of information about objects, tasks, and decision alternatives. [1] [2] A goal of this approach is to understand the extent of influence that affect has on cognitive functioning. [1]
In personality psychology, the lexical hypothesis [1] (also known as the fundamental lexical hypothesis, [2] lexical approach, [3] or sedimentation hypothesis [4]) generally includes two postulates: 1. Those personality characteristics that are important to a group of people will eventually become a part of that group's language. [5] and that ...
Hypothesis based perception ("HyPercept") is understood as a bottom-up (data-driven and context-dependent) cuing of hypotheses that is interleaved with a top-down verification. The acquisition of schematic hierarchical descriptions and their gradual adaptation and revision can be described as assimilation and accommodation .
Closely related to Spearman's hypothesis is the hypothesis that the magnitude of certain group differences correlates with within-group heritability estimates. Arthur Jensen and J. Phillippe Rushton, for example, reported in 2010 that the found psychometric meta-analytic correlation between g-loadings and heritability estimates was 1. [5]
The male warrior hypothesis predicts that because males may have historically remained in the groups in which they were born rather than moving away at adulthood (see patrilocality), they have a higher overall relatedness to their group than the female members, who would have moved to their new husbands’ group upon marriage.
