Emotional Responses to Virtual Public Speaking Tasks with Audience Manipulation

A study by Evania Fasya involving 102 participants with varied public speaking anxiety levels. Participants delivered speeches to virtual audiences of varying sizes and attitudes, with physiological signals, speech characteristics, subjective stress, and audience evaluations measured. The dataset was last updated on June 15, 2026.

Use Cases

• Analyze the relationship between audience attitude and subjective stress levels based on the measured emotional responses.
• Investigate the moderating effect of public speaking anxiety levels on physiological signals like heart rate.
• Study the impact of virtual audience size on participant trust and evaluation.
• Examine the discordance between different emotional response measures (e.g., nervousness vs. heart rate) under experimental conditions.

Strengths

• Includes data from 102 participants, providing a substantive sample size.
• Captures multimodal data: physiological signals, speech characteristics, subjective ratings, and audience evaluations.
• Manipulates two independent variables: audience size (2 or 6) and audience attitude (encouraging or critical).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect bias inherent to the specific experimental setup and participant pool.
