to their size. The smaller animals require less water and are better able to survive in areas where water is scarce. Hoarding is also found in some species of birds and even rodents. This hoarding is typically food. The birds and rodents commonly store up food and hide it in a place that is out of reach for other animals. Scarcity mentality Scarcity can be more than a physical limitation. It also involves the frontal lobe in the brain, which is in charge of making decisions. It can also affect how people think and feel. When there are not enough resources, whether financial or time, challenges are created for the human cognitive system. This presents problems such as impulsive behavior which likely impairs performance. These people also exhibit lowered intellectual abilities and more forgetful behaviors. With these impairments and deficits, performance is actually lowered and that causes behaviors that actually worsen the effects of scarcity.
