The Social Dimension of Stress: Experimental Manipulations of Social Support and Social Identity in the Trier Social Stress Test

The Social Dimension of Stress: Experimental Manipulations of Social Support and Social Identity in the Trier Social Stress Test

Previous research on the social dimension of stress has focused on two important variables: social identity and social support. This protocol introduces an effective experimental manipulation of these two social variables and describes their implementation in a standard stress induction paradigm (Trier Social Stress Test).

Social Threat-Safety Test Uncovers Psychosocial Stress-Related Phenotypes

The social threat-safety test allows a simultaneous assessment of social avoidance development as a measurement of aversive conditioned learning and social threat-safety discrimination ability, both utilized to identify stress-susceptible and stress-resilient individuals within a single group of chronically socially defeated male...

Hardy-Weinberg Principle

Hardy-Weinberg Principle

Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

Class Simulation
ExpandBegin by opening a new spreadsheet file. Following the Hardy-Weinberg equation where p is the frequency of a dominant allele A in a population, and q is defined as the frequency of a recessive allele B, input frequency p of allele A into cell B2, and frequency q of allele B into cell B3.
Assign the value 0.5 to cell C2.
Following the 1 – p = q equation, enter the formula “= 1 – C2” into cell C3 to calculate the frequency q of allele B. NOTE: Cells...

Hardy-Weinberg and Genetic Drift

Evolutionary change is interesting and important to study, but changes in populations occur over long periods of time and in huge physical spaces and are therefore very difficult to measure. In general, studying phenomena like this requires the use of mathematical models which are built using parameters that can be conveniently measured. These models are then used to make predictions about how changes to the system might affect the outcome.
For example, changes to the frequency of genetic...

Area of Science:

Positive psychology
Disability sport psychology

Background:

Replication and extension of Martin et al. (2015) research.
Focus on positive psychological factors in disability sport.

Purpose of the Study:

Predict life quality and sport engagement in wheelchair rugby athletes.
Examine the role of grit, hardiness, resilience, and social support.

Main Methods:

Survey of 87 adult wheelchair rugby athletes with various disabilities.
Assessment of grit, hardiness, resilience, social support, life satisfaction, and sport engagement.

Main Results:

Resilience was a significant predictor of life satisfaction.
Grit, social support, resilience, and hardiness significantly predicted sport engagement.
These factors accounted for 32% of life satisfaction variance and 37% of sport engagement variance.

Conclusions:

High resilience is linked to higher quality of life.
Grit, resilience, hardiness, and social support are associated with greater sport engagement.
Findings partially replicate and extend previous research on psychological factors in adaptive sports.
