Mate Choice01:20

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
Natural and Artificial Concepts01:24

Natural and Artificial Concepts

In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint Vincent in...
How Data are Classified: Categorical Data01:11

How Data are Classified: Categorical Data

A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
Concepts and Prototypes01:24

Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...
Data Collection by Observations01:08

Data Collection by Observations

Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...
Phylogeny01:23

Phylogeny

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Area of Science:

  • Cognitive Science
  • Comparative Psychology
  • Avian Cognition

Background:

  • Historically, nonhuman abstract concept formation, particularly in birds, was doubted.
  • Ethological arguments suggested survival necessitated basic concept understanding, but lacked cognitive process validation.
  • Pioneering research in the 1960s began to provide empirical data supporting complex avian cognition.

Purpose of the Study:

  • To investigate abstract numerical concept formation in the Gray parrot (Psittacus erithacus).
  • To compare the cognitive abilities of avian subjects to those of apes and human children regarding number concepts.
  • To explore the learning mechanisms of abstract concepts in parrots.

Main Methods:

  • Review of research focusing on numerical concepts in the Gray parrot, specifically the subject Alex.
  • Analysis of Alex's understanding of number symbols as abstract representations.
  • Comparison of Alex's performance with data from apes and young human children.

Main Results:

  • The Gray parrot, Alex, demonstrated understanding of number symbols as abstract representations of quantities.
  • Alex's numerical concept formation compared favorably to that of apes and young human children.
  • The learning process for these concepts in Alex appeared more human-like than ape-like.

Conclusions:

  • Gray parrots possess the capacity for abstract numerical concept formation.
  • Avian cognitive abilities, particularly in Gray parrots, are comparable to those of primates and humans in certain domains.
  • Parrots may learn abstract concepts through mechanisms more akin to human learning than ape learning.
