## Segment-Level Data Structure

### JSON Structure in "Segments" Field

Each utterance includes time-aligned segment-level tonality data stored as a JSON array string in the CSV.

**Structure**:
```json
[
  {
    "startTime": <milliseconds>,
    "endTime": <milliseconds>,
    "trust": <0-100>,
    "reciprocity": <0-100>,
    "empathy": <0-100>,
    "cognitive": <0-100>,
    "attention": <0-100>
  }
]
```

**Real Example**:
```json
[{
  "startTime": 0,
  "endTime": 4284.083333333333,
  "trust": 75,
  "reciprocity": 93,
  "empathy": 76,
  "cognitive": 96,
  "attention": 80
}]
```

### Segment Field Definitions

| Field | Type | Unit | Description |
|-------|------|------|-------------|
| `startTime` | Float | Milliseconds | Segment start time from utterance beginning |
| `endTime` | Float | Milliseconds | Segment end time from utterance beginning |
| `trust` | Integer | 0-100 | Trust tonality score for this segment |
| `reciprocity` | Integer | 0-100 | Reciprocity score for this segment |
| `empathy` | Integer | 0-100 | Empathy resonance score for this segment |
| `cognitive` | Integer | 0-100 | Cognitive energy score for this segment |
| `attention` | Integer | 0-100 | Attention score for this segment |

**Notes**:
- Most utterances contain a single segment (entire utterance)
- Times in milliseconds with decimal precision
- Segment scores may differ from utterance-level indices in multi-segment utterances
- To convert milliseconds to seconds: `seconds = milliseconds / 1000`

## Missing Data Codes

### How Missing Data is Represented

| Field Type | Missing Data Representation |
|-----------|----------------------------|
| String fields (Sub_Modifier, Ambivalex, Notes) | Empty string `""` |
| Numeric fields | No missing data (all utterances fully annotated) |
| Segments | No missing data (all utterances have segment data) |

**Important**: 
- There is **NO use of** `-999`, `NULL`, `NA`, or other special missing data codes
- Empty string `""` indicates "not applicable" for optional fields
- All tonality indices are complete (no missing values)

| Utterances per Batch | 18 |
| Single Speaker | Yes (Ronda) |
| Language | English (American) |
| Recording Period | Dec 19, 2025 - Jan 23, 2026 |
| Total Duration | ~10 minutes |

### Index Distributions

*Note: Actual statistical summaries (mean, SD, min, max) should be calculated from the complete dataset.*

**Expected Patterns**:
- Cognitive_Energy_Index: Known systematic elevation (typically 90-100)
- Other indices: Expected to vary by Primary_Intention category
- See METHODOLOGY.md for quality control discussion

---

## Known Issues & Limitations

### Cognitive Energy Systematic Bias

**Issue**: Cognitive_Energy_Index shows systematic elevation across most utterances, regardless of Primary_Intention category.

**Possible Causes** (as noted in dataset documentation):
1. Speaker's ecological style (natural high-energy delivery)
2. Lexical content effects
3. Practitioner bias in scoring

**Resolution**: Intentionally retained for transparency and to reflect ecological reality of speech production. Researchers should account for this bias in analyses.

**Impact**: 
- Trust and Empathy Resonance indices most affected
- Suggests need for speaker-specific normalization in some applications
- Does not invalidate other tonality measures

### Single-Speaker Limitation

- All 144 files from same speaker (Ronda)
- Findings may not generalize to other speakers
- Multi-speaker extension needed for broader applicability

### Controlled Environment

- Professional studio recordings
- May not reflect naturalistic speech conditions
- Scripted content (not spontaneous speech)

## Usage Notes

### Loading Data in Python

```python
import pandas as pd
import json

# Load combined CSV
df = pd.read_csv('ALL_TONALITY_DATA_COMBINED.csv')

# Parse Segments JSON
df['Segments_Parsed'] = df['Segments'].apply(json.loads)

# Access first segment's trust score
first_segment_trust = df['Segments_Parsed'].iloc[0][0]['trust']
```

### Loading Data in R

```r
library(readr)
library(jsonlite)

# Load CSV
data <- read_csv('ALL_TONALITY_DATA_COMBINED.csv')

# Parse Segments JSON
data$Segments_Parsed <- lapply(data$Segments, fromJSON)

# Access segment data
first_segment <- data$Segments_Parsed[[1]][[1]]
```

### Filtering by Intention

```python
# Get all Attention utterances
attention_data = df[df['Primary_Intention'] == 'Attention']

# Get all utterances with ambivalence
ambivalent_data = df[df['Ambivalex'] == 'ambivalex']

# Get Trust utterances with calm modifier
trust_calm = df[
    (df['Primary_Intention'] == 'Trust') & 
    (df['Sub_Modifier'] == 'calm')
]
```
