Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

1.1K
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Optimal Foraging

14.2K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Production Efficiency01:01

Production Efficiency

19.1K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Energy Budgets00:51

Energy Budgets

11.1K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Summary

People value environmental resources by reacting negatively to destructive land uses, which drives donations more than park appeal. Neuroimaging reveals distinct brain activity linked to these environmental valuation responses.

Area of Science:

  • Environmental Psychology
  • Neuroeconomics
  • Behavioral Economics

Background:

  • Public valuation of environmental resources is often assessed via willingness-to-pay surveys.
  • These surveys can elicit complex affective responses, including negative reactions to destructive land uses.

Purpose of the Study:

  • To investigate the affective processes underlying environmental resource valuation.
  • To compare the influence of park iconicity versus land use destructiveness on donation behavior.
  • To explore the neural correlates of environmental valuation using neuroimaging.

Main Methods:

  • Behavioral experiments assessing donation choices for park protection.
  • Neuroimaging experiments (fMRI) measuring brain activity during valuation tasks.
  • Analysis correlating brain activity (nucleus accumbens, anterior insula, medial prefrontal cortex) with donation behavior and pro-environmental attitudes.

Main Results:

  • Land use destructiveness was a stronger motivator for donations than park iconicity.
  • Anterior insula activity correlated with negative responses to destructive uses and predicted increased donations.
  • Medial prefrontal cortex activity was modulated by the interaction of park iconicity and land use, predicting reduced donations.
  • Individuals with stronger pro-environmental attitudes exhibited greater anterior insula activation in response to destructive land uses.

Conclusions:

  • Negative affective responses to destructive land uses significantly influence environmental valuation, potentially outweighing positive responses to the resources themselves.
  • Neuroimaging offers a complementary approach to surveys for understanding distinct affective components of environmental valuation.
