Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

7.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Role of Affect in Interpersonal Attraction01:24

Role of Affect in Interpersonal Attraction

223
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The Intermediate Value Theorem01:25

The Intermediate Value Theorem

273
The Intermediate Value Theorem is a foundational result in calculus that guarantees the existence of solutions within certain intervals for continuous functions. Formally, the Intermediate Value Theorem states that if a function f is continuous on the closed interval [a, b], and if N is any value between f(a) and f(b), then there exists at least one c ∈ (a, b) such that f(c) = N. This theorem is instrumental in proving the existence of roots and in analyzing the behavior of continuous...

The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

287
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

214
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Disassembly of Intermediate Filaments01:35

Disassembly of Intermediate Filaments

2.7K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.
Keratin proteins, found at the cell periphery near cell junctions, undergo a cycle of assembly and disassembly. In Type...

Summary

Focusing on how physical activity (PA) makes people feel, not just its health benefits, can improve engagement. Affective responses to PA are key predictors of behavior and influenced by genetic factors.

Area of Science:

  • Exercise Science
  • Behavioral Genetics
  • Public Health

Background:

  • Regular physical activity (PA) is vital for health, yet physical inactivity is a major global mortality risk.
  • A significant gap exists between knowledge of PA benefits and actual engagement in regular activity.

Purpose of the Study:

  • To propose affective response to PA as an intermediate phenotype explaining the link between genetics and PA behavior.
  • To shift focus from PA's health outcomes to the immediate feelings experienced during activity.

Main Methods:

  • Review of empirical evidence linking affective response during PA to future PA behavior.
  • Systematic review of research on single nucleotide polymorphisms (SNPs) associated with affective responses to PA.

Main Results:

  • Affective responses to PA are significant predictors of subsequent physical activity.
  • Genetic variability, specifically single nucleotide polymorphisms (SNPs), influences these affective responses.

Conclusions:

  • Understanding affective responses to PA is crucial for bridging the gap between knowing and doing.
  • Investigating affective response as a phenotype will refine our understanding of how genetic factors influence PA behavior and inform intervention development.
