Bystander Effect02:09

Bystander Effect

10.3K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Regression Toward the Mean01:52

Regression Toward the Mean

7.2K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Area of Science:

  • Nutrition Science
  • Public Health
  • Obesity Research

Background:

  • Dietary behaviors, including snacking, can be either healthful or detrimental.
  • Snacking is a popular dietary behavior with potential implications for diet quality.

Purpose of the Study:

  • To critically review the literature on snacking.
  • To evaluate the role of snacking in energy balance and its association with overweight/obesity.

Main Methods:

  • Critical review of existing scientific literature.
  • Analysis of evidence linking snacking to energy intake and body weight.
  • Identification of plausible mechanisms connecting snacking to obesity.

Main Results:

  • Strong evidence suggests snacking is associated with increased energy intake.
  • The direct translation of snacking to body weight is less clear due to methodological limitations.
  • Corrected for limitations, evidence implicates snacking in the high prevalence of overweight and obesity.

Conclusions:

  • Snacking is a significant dietary behavior that may contribute to positive energy balance and the promotion of overweight/obesity.
  • Further research is recommended to better understand and optimize snacking behaviors for improved health outcomes.
