## Diagram: Classification of Spatial Cognition Tasks
### Overview
The image is a conceptual diagram that categorizes various cognitive tasks related to spatial processing into two primary domains: **Large-scale spatial cognition** and **Small-scale spatial cognition**. Each domain contains specific tasks represented as colored boxes, with icons indicating the task type. A legend at the bottom defines the color-coding scheme and icon meanings.
### Components/Axes
The diagram is divided into two main panels:
1. **Left Panel:** Titled "Large-scale spatial cognition" (black header, white text).
2. **Right Panel:** Titled "Small-scale spatial cognition" (black header, white text).
**Legend (Bottom of Image):**
* **Color Categories:**
* Blue square: Spatial visualization
* Orange square: Spatial perception
* Red square: Visuospatial working memory
* Green square: Spatial orientation
* Purple square: Selective spatial attention
* **Icon Types:**
* Document icon: QA task
* Hand icon: Interactive task
### Detailed Analysis
#### Large-scale spatial cognition (Left Panel)
All tasks in this panel are colored **green**, corresponding to the **Spatial orientation** category. Each task box contains a document icon (QA task) on its left side.
* **Tasks Listed (Top to Bottom, Left to Right):**
1. Distance estimation
2. Map sketching
3. Direction estimation
4. Route retracing
5. Shortcut discovery
#### Small-scale spatial cognition (Right Panel)
This panel contains tasks from multiple cognitive categories, distinguished by color.
* **Spatial visualization (Blue):**
* Perspective taking (with document icon)
* Mental rotation (with document icon)
* **Spatial perception (Orange):**
* Water level (with document icon)
* Judgement of line orientation (with document icon)
* **Visuospatial working memory (Red):**
* Spatial addition (with hand icon - Interactive task)
* Cambridge spatial working memory (with hand icon - Interactive task)
* Corsi block tapping (with hand icon - Interactive task)
* **Selective spatial attention (Purple):**
* Selective attention (with document icon)
* **Spatial orientation (Green):**
* Maze completion (with hand icon - Interactive task)
* **Other (Color not explicitly matched in legend):**
* Minnesota paper form board (Blue - Spatial visualization, with document icon)
### Key Observations
1. **Domain Separation:** The diagram makes a clear distinction between tasks involving navigation and orientation in large environments (left) and tasks involving manipulation and perception of objects in immediate space (right).
2. **Task Type Distribution:** Large-scale tasks are uniformly categorized as "Spatial orientation" and are all "QA tasks." Small-scale tasks are more diverse, spanning four cognitive categories, and include a mix of "QA tasks" and "Interactive tasks."
3. **Icon Consistency:** The "Interactive task" icon (hand) is exclusively associated with tasks in the "Visuospatial working memory" category (except for Maze completion), suggesting these tasks require active manipulation or response.
4. **Potential Anomaly:** The "Maze completion" task is colored green (Spatial orientation) but is placed in the Small-scale panel and is an Interactive task. This may indicate it bridges both domains or is considered a small-scale application of orientation skills.
### Interpretation
This diagram serves as a taxonomic framework for understanding spatial cognition research. It suggests that spatial ability is not a single construct but is composed of distinct sub-functions (orientation, visualization, perception, memory, attention) that are engaged differently depending on the scale of the spatial problem.
The separation implies that proficiency in large-scale navigation (e.g., finding a shortcut) may rely on different cognitive processes than proficiency in small-scale object manipulation (e.g., mental rotation). The inclusion of task types (QA vs. Interactive) adds a methodological layer, showing how these cognitive functions are typically assessed—through verbal/report-based questions or hands-on performance tasks.
For a researcher or clinician, this map could help in selecting appropriate assessments for specific spatial deficits or in designing experiments that isolate particular cognitive components. The outlier status of "Maze completion" highlights that some tasks are complex and may integrate multiple spatial sub-skills across the large/small-scale divide.
