Rapid Rate Component

The Rapid Rate component provides a multi-dimensional rating interface for quick assessments across multiple attributes. Participants can rate several dimensions simultaneously using parallel sliders.

Key Features

• Multiple parallel rating dimensions
• Quick drag-across interaction
• Custom dimension labels
• Reference lines for comparisons
• Optional countdown timer
• Responsive design

When to Use

Use the Rapid Rate component when you need to:

• Collect ratings across multiple dimensions quickly
• Assess emotional states (valence, arousal, dominance)
• Evaluate products or stimuli on several criteria
• Gather multi-attribute judgments in time-limited scenarios
• Compare ratings to previous responses

Setting Up Dimensions

Dimensions are configured as an array:

dimensions: [
  {
    label: "Valence",
    minLabel: "Negative",
    maxLabel: "Positive"
  },
  {
    label: "Arousal",
    minLabel: "Calm",
    maxLabel: "Excited"
  },
  {
    label: "Dominance",
    minLabel: "Submissive",
    maxLabel: "Dominant"
  }
]

With Initial Values

dimensions: [
  {
    label: "Quality",
    minLabel: "Poor",
    maxLabel: "Excellent",
    initialValue: 50
  },
  {
    label: "Value",
    minLabel: "Overpriced",
    maxLabel: "Great Value",
    initialValue: 50
  }
]

Data Collection

The Rapid Rate component stores all dimension values:

{
  "ratings": {
    "Valence": 72,
    "Arousal": 45,
    "Dominance": 58
  },
  "responseTime": 3456,
  "timestamps": {
    "displayed": 1621453287000,
    "firstInteraction": 1621453288500,
    "submitted": 1621453290456
  },
  "interactions": [
    { "dimension": "Valence", "time": 1621453288500, "value": 65 },
    { "dimension": "Valence", "time": 1621453289100, "value": 72 },
    { "dimension": "Arousal", "time": 1621453289400, "value": 45 }
  ]
}

Common Dimension Sets

Affect Grid (Russell's Model)

dimensions: [
  { label: "Valence", minLabel: "Unpleasant", maxLabel: "Pleasant" },
  { label: "Arousal", minLabel: "Sleepy", maxLabel: "Activated" }
]

SAM (Self-Assessment Manikin)

dimensions: [
  { label: "Pleasure", minLabel: "Unhappy", maxLabel: "Happy" },
  { label: "Arousal", minLabel: "Calm", maxLabel: "Excited" },
  { label: "Dominance", minLabel: "Controlled", maxLabel: "In Control" }
]

Product Attributes

dimensions: [
  { label: "Quality", minLabel: "Low", maxLabel: "High" },
  { label: "Price", minLabel: "Too Expensive", maxLabel: "Great Value" },
  { label: "Design", minLabel: "Unattractive", maxLabel: "Beautiful" }
]

Best Practices

1. Limit Dimensions: Keep to 2-5 dimensions for quick responses
2. Clear Labels: Use concise, understandable endpoint labels
3. Consistent Scales: Use similar scales across related assessments
4. Order Strategically: Put most important dimensions first
5. Time Constraints: Consider using countdown for spontaneous ratings
6. Reference Lines: Use for repeated measures to show change

Rapid Rate vs Other Rating Components

Component	Best For
Rapid Rate	Multiple dimensions simultaneously
VAS Rating	Single dimension, precise measurement
Likert Scale	Standard survey questions
Continuous Rating	Real-time ratings during stimuli
