1. Concept of Mental Maps or Cognitive Maps

Mental maps, also known as cognitive maps, refer to mental representations of physical spaces or environments that individuals construct based on their perceptions, experiences, and spatial knowledge. These maps are internal representations that help individuals navigate and interact with their surroundings, guiding spatial behaviors and decision-making processes.

• Formation of Cognitive Maps: Cognitive maps are formed through sensory perception, learning, and memory consolidation. As individuals explore and experience environments, they encode spatial information such as landmarks, routes, distances, and relationships between locations. These mental representations are stored in the brain's hippocampus and cortex, facilitating navigation and spatial orientation.

• Components of Cognitive Maps: Cognitive maps consist of spatial relationships and hierarchical structures that organize spatial knowledge. They include landmarks (distinctive features), paths (routes connecting landmarks), nodes (points of interest), and boundaries (perceptual edges of spaces). Cognitive maps may also incorporate subjective elements such as preferences, emotions, and cultural interpretations of space.

2. Relationship Between Environmental Perception and Environmental Situation

Environmental perception influences how individuals interpret and interact with their surroundings, shaping cognitive maps and spatial behaviors:

• Perception of Environmental Features: Environmental perception involves sensory processes (vision, hearing, touch) and cognitive interpretations of physical features (landscapes, buildings, natural elements). Perception is influenced by individual characteristics (age, experience), environmental conditions (lighting, noise), and psychological factors (attention, mood).

• Formation of Cognitive Maps: Perception contributes to the construction of cognitive maps by encoding sensory information into mental representations. Perceived landmarks, spatial layouts, and environmental cues shape cognitive maps, influencing navigation strategies, spatial orientation, and decision-making.

• Spatial Cognition and Wayfinding: Spatial cognition refers to mental processes involved in understanding spatial relationships and navigating environments. Environmental perception informs spatial cognition by guiding attention, memory encoding, and route planning based on perceived affordances (functional opportunities) and constraints (barriers or obstacles).

3. Factors Influencing Environmental Perception

Several factors influence how individuals perceive and mentally represent their environments:

• Physical Environment: Environmental characteristics such as architecture, urban design, natural landscapes, and infrastructure impact sensory experiences and spatial perceptions. Well-designed environments with clear signage, accessible pathways, and aesthetically pleasing features enhance environmental legibility and navigation.

• Cultural and Social Context: Cultural norms, social practices, and historical contexts influence perceptions of space and place. Cultural differences in spatial cognition may affect preferences for privacy, territoriality, and spatial layouts in residential, urban, or natural settings.

• Individual Differences: Personal traits (e.g., age, gender, cognitive abilities) and psychological factors (e.g., anxiety, familiarity) shape individual perceptions and spatial behaviors. Age-related changes in spatial cognition, for instance, may affect navigational abilities and reliance on cognitive maps.

4. Application in Environmental Design and Planning

Understanding the relationship between environmental perception and cognitive maps informs design strategies and planning interventions:

• User-Centered Design: Designing environments that align with users' cognitive maps and perceptual preferences promotes user satisfaction, wayfinding efficiency, and safety. User-centered approaches consider diverse user needs and experiences to enhance environmental legibility and navigation.
