Problem-Solving

Problem-Solving

Effective problem-solving consists of two steps: 1. identifying the problem and 2. selecting the appropriate problem-solving strategy (i.e., a plan of action used to find a solution). Humans use four problem-solving strategies:

Cognitive Learning

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Optimal Foraging

Optimal Foraging

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.

Impact: Problem Solving

Impact: Problem Solving

In an experiment conducted during a Mars mission, a rover propels a projectile with an initial velocity, and the projectile rebounds after colliding with the Martian surface. To ascertain the maximum height attained by the projectile after this collision, the known restitution coefficient and acceleration due to gravity are employed.
By designating the launch point as the origin and utilizing kinematic equations, the vertical component of the projectile's velocity at the point of impact is...

Collisions in Multiple Dimensions: Problem Solving

Collisions in Multiple Dimensions: Problem Solving

In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Robbers Cave

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Area of Science:

Comparative cognition
Animal behavior
Evolutionary psychology

Background:

Cooperation's cognitive roots are increasingly found beyond humans.
Selective pressures driving cooperative mechanisms' evolution are poorly understood.

Purpose of the Study:

To investigate the cognitive underpinnings of collaborative behavior in New Caledonian crows.
To determine if tool-making abilities correlate with understanding cooperative causality and inequity.

Main Methods:

Observational studies of New Caledonian crows' tool-making and social interactions.
Behavioral experiments assessing responses to cooperative tasks and inequity.

Main Results:

Crows demonstrated collaborative behavior, likely through prior experience transfer.
No evidence of understanding cooperative causality or sensitivity to inequity was found.
Tool manufacture and mobbing behaviors did not drive cooperative cognition evolution in this species.

Conclusions:

Cooperative cognition is not a prerequisite for collaborative behavior.
Causal cognition can be domain-specific; tool use does not imply social tool understanding.
The evolution of cooperation requires specific selective pressures beyond tool manufacture or mobbing.
