UX Psychology for Frontend Design

Apply psychological principles to create more effective, engaging user interfaces.

Workflow

1. Identify Design Goal

Determine the primary objective:

• Conversion: Pricing, signup, checkout
• Engagement: Retention, time-on-site, repeat visits
• Usability: Task completion, error reduction
• Trust: Credibility, security perception

2. Select Relevant Concepts

Based on goal, consult the appropriate reference file:

Goal	Reference File	Key Concepts
Conversion	references/cognitive-biases.md	Anchoring, Loss Aversion, Framing
Engagement	references/engagement.md	Gamification, Variable Reward, Social Proof
Usability	references/behavioral-patterns.md	Cognitive Load, Progressive Disclosure, Default Effect
Visual Appeal	references/visual-design.md	Aesthetic-Usability, Visual Hierarchy

3. Apply Concepts to Design

For each selected concept:

1. Read the detailed pattern from reference file
2. Identify specific UI elements to apply it to
3. Implement with code examples provided

Common Design Patterns

Pricing Page

Applied concepts:
- Anchoring: Show highest-priced plan first
- Decoy Effect: Make middle plan look like best value
- Social Proof: "Most Popular" badge
- Visual Anchor: Highlight recommended plan visually

Signup Flow

Applied concepts:
- Foot-in-the-Door: Start with email only, ask details later
- Cognitive Load: One task per screen
- Goal Gradient: Show progress bar
- Default Effect: Pre-select recommended options

E-commerce Product Page

Applied concepts:
- Scarcity: "Only 3 left in stock"
- Social Proof: Reviews and ratings
- Loss Aversion: "Don't miss out..."
- Aesthetic-Usability: High-quality product images

Canonical layout

• Category folders at repo root (e.g. development/, documents/, data/, ...)

• Case conflicts are resolved with {name}-{owner}-{repo} suffixes (fallback: -{short-hash}).

Archive status

• Live badges above are sourced from claude-skill-registry-core stats.json.
• Counts in this README are intentionally dynamic, not hardcoded.
• If the badges look stale, refresh the core build/index pipeline rather than editing numbers here.
