Each card has a number on one side and color on the other. Which card or cards must be turned over to test the idea that if a card shows an even number on one face, then its opposite face is blue? The Wason selection task (or four-card problem) is a logic puzzle devised by Peter Cathcart Wason in 1966.

Selective exposure is a theory within the practice of psychology, often used in media and communication research, that historically refers to individuals' tendency to favor information which reinforces their pre-existing views while avoiding contradictory information.
Socioemotional selectivity theory (SST; developed by Stanford psychologist Laura L. Carstensen) is a life-span theory of motivation. The theory maintains that as time horizons shrink, as they typically do with age, people become increasingly selective, investing greater resources in emotionally meaningful goals and activities.
This theory assumes that once the task set is implemented, it stays in a given state of activation until it has to be changed, such as when a new task is presented. [7] Consequently, proponents argue, switch costs arise from an endogenous, executive control process that reconfigures the cognitive system to implement the relevant task set for ...
A pessimal sorting algorithm that is guaranteed to complete in finite time; however, its efficiency can be arbitrarily bad, depending on its configuration. The worstsort algorithm is based on a bad sorting algorithm, badsort. The badsort algorithm accepts two parameters: L, which is the list to be sorted, and k, which is a recursion depth.
More than 38 million Americans have diabetes, and between 90% and 95% of them have type 2 diabetes. While most are adults over the age of 45, an increasing number of children and teens are also ...
The theory was popular in the 1970s and 1980s, when it was used as a heuristic device, but lost importance in the early 1990s, when it was criticized by several empirical studies. [ 5 ] [ 6 ] A life-history paradigm has replaced the r / K selection paradigm, but continues to incorporate its important themes as a subset of life history theory. [ 7 ]
