An example is the relation "is equal to", because if a = b is true then b = a is also true. If R T represents the converse of R, then R is symmetric if and only if R = R T. [2] Symmetry, along with reflexivity and transitivity, are the three defining properties of an equivalence relation. [1]
Although its mechanistic underpinnings are still debated, the relationship between RT and cognitive ability today is as well-established an empirical fact as any phenomenon in psychology. [3] A 2008 literature review on the mean correlation between various measures of reaction time and intelligence was found to be −0.24 ( SD = 0.07).
Thus, a d-variate distribution is defined to be mirror symmetric when its chiral index is null. The distribution can be discrete or continuous, and the existence of a density is not required, but the inertia must be finite and non null. In the univariate case, this index was proposed as a non parametric test of symmetry. [2]
The cheerleader effect, also known as the group attractiveness effect or the friend effect, [1] is a proposed cognitive bias which causes people to perceive individuals as 1.5–2.0% more attractive in a group than when seen alone. [2] The first paper to report this effect was written by Drew Walker and Edward Vul, in 2013. [3]
In social psychology, interpersonal attraction is most-frequently measured using the Interpersonal Attraction Judgment Scale developed by Donn Byrne. [1] It is a scale in which a subject rates another person on factors such as intelligence, knowledge of current events, morality, adjustment, likability, and desirability as a work partner.
The four relational models are as follows: Communal sharing (CS) relationships are the most basic form of relationship where some bounded group of people are conceived as equivalent, undifferentiated and interchangeable such that distinct individual identities are disregarded and commonalities are emphasized, with intimate and kinship relations being prototypical examples of CS relationship. [2]
Cognitive valence theory (CVT) is a theoretical framework that describes and explains the process of intimacy exchange within a dyad relationship.Peter A. Andersen, [who?] PhD created the cognitive valence theory to answer questions regarding intimacy relationships among colleagues, close friends and intimate friends, married couples and family members. [1]
The study by Zajonc et al. [1] found that the faces of spouses become more similar over time and that this similarity is positively correlated with couples' satisfaction in their marriage. The researchers suggest that this may be due to couples sharing similar environments and experiences, leading to similar facial features as a result.
