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.

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...

Instinctive Drift

Instinctive Drift

Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

The Nativist Approach

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Purposive Learning

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

Cognitive Science

Background:

Early adversity is often viewed as leading to maladaptive behaviors.
Conditional adaptation theory suggests behaviors are adaptive to expected environments.

Purpose of the Study:

To investigate if early institutionalization affects exploration-exploitation strategies.
To determine if these strategies are context-dependent and adaptive.

Main Methods:

Assessed exploration-exploitation strategies in youth with and without institutionalization history.
Used a laboratory-based experimental paradigm to examine strategy use.
Compared task success based on strategy and environmental condition (generous vs. restricted).

Main Results:

Youth with prior institutionalization showed less exploration and more exploitation.
Exploration strategies were more successful in generous environments.
Exploitation strategies were more successful in restricted environments.

Conclusions:

Early institutionalization impacts exploration-exploitation strategies.
The success of these strategies is context-dependent.
Behavioral phenotypes following early experience align with expected future environments.
