Definition
The Five Task Model DOI is a theoretical framework proposing that cognition across biological and artificial systems is organized around five irreducible domains of informational control through which organisms interpret environmental events and regulate behavior change (B1→B2) DOI under the constraints of the Energy–Safety–Reproduction (ESR) triad DOI.
Living systems operate within General Informational Flow DOI, where environmental variation continuously produces informational events. In order to maintain viability, organisms must interpret these events and regulate their behavior accordingly.
The Five Task Model proposes that environmental informational variation is not processed through an unlimited set of pathways. Instead, adaptive regulation consistently occurs through a limited set of recurrent informational task domains DOI.
Comparative analysis across more than 1,530 species DOI indicates that informational situations requiring adaptive regulation cluster into five irreducible task domains. Each domain represents a distinct informational problem requiring a qualitatively different architecture of behavior change.
These domains appear across evolutionary lineages in a gated, sequential, and cumulative order DOI, forming the informational architecture through which organisms regulate their interactions with the environment.
Within this architecture, tasks represent informational control operations through which organisms regulate behavior change (B1→B2) relative to informational situations in the environment. Tasks therefore are not behaviors themselves but control operations that structure how behavior change is selected and regulated.
When an informational event is recognized as belonging to a specific domain of adaptive concern, it becomes an informational task DOI requiring the selection of an appropriate behavior change.
In this sense, cognition functions as a system for organizing informational environments into distinct domains of control, allowing organisms to interpret environmental events and regulate appropriate behavior change in response to them.

The Five Informational Tasks
The model identifies five recurrent domains of informational control:
Task 1 — Binary Environmental Control
Regulating exposure to environmental states through binary orientation (approach, withdrawal, or maintained position).
Task 2 — Distal Engagement Control
Selecting behavior change relative to independently moving entities before physical contact occurs.
Task 3 — Perception-Shaping Control
Regulating behavior change that influences how other agents interpret the situation through signals, displays, concealment, or other communicative actions.
Task 4 — Group-Dynamics Control (Collaboration and Competition)
Selecting behavior change relative to alliances, roles, and structured group interactions involving cooperation and competition.
Task 5 — Rule-Guided Formalized Symbolic Control
Regulating behavior change through shared symbolic systems such as language, norms, rules, and abstract representations.

Figure 1. The Five Tasks as a cumulative scaffold of informational control.
Each vertical block represents a species group, defined by the number of informational tasks it can reliably control in daily life. Boxes indicate the five tasks identified in this study, ordered from bottom to top: (1) Binary orientation to environmental states, (2) Distal engagement with free-moving entities, (3) Perception-shaping and signalling, (4) Coalition alignment within structured groups, and (5) Rule-guided abstraction through formal symbolic systems.
Tasks are cumulative: groups expressing later tasks also retain control over all earlier tasks. Across the dataset, no stable lineages were observed that skip tasks or reorder them. Transitional cases occupy adjacent spans between groups but do not introduce additional tasks. The figure is descriptive rather than mechanistic and summarizes the empirical task structure observed across 1,530 species. Broader conceptual extensions of this framework are discussed elsewhere (Frolov, 2022; 2024; DOI: https://doi.org/10.17605/OSF.IO/AZKVY ).

Architectural Principle
The Five Task Model proposes that cognition is fundamentally an informational control architecture.
Within this architecture:
The same architecture that organizes cognition across biological life also provides the structural basis for analyzing artificial systems in substrate-neutral terms.
The Five Task Model proposes that cognition is fundamentally an informational control architecture.
Within this architecture:
- environmental variation produces informational events
- events are interpreted through domain recognition
- domain recognition activates the relevant informational task
- the cognitive-behavioral controller selects and regulates behavior change (B1→B2)
The same architecture that organizes cognition across biological life also provides the structural basis for analyzing artificial systems in substrate-neutral terms.
Evolutionary Tracks
The five evolutionary tracks visualize the cumulative expansion of cognitive architecture across the major groups of living systems. Each track corresponds to a species group defined by the number of informational domains and tasks it must and can regulate, from environmental control in LUCA-derived lineages to the full five-domain architecture of symbolic systems. Together, the tracks show that cognition evolves through progressive architectural accumulation rather than through replacement of earlier task structures.
