Notes on Introduction, Credibility, and Practice in Public Speaking

Notes on Public Speaking: Introduction, Credibility, Practice, and Classroom Dynamics

• Introduction

  • The introduction’s primary purpose is to get the audience’s attention.
  • Lucas (Art of Public Speaking, 2023) states that audiences are egocentric.
  • Egocentric audiences mean they focus on themselves and their interests; this shapes how you should present to them.
  • Establishing credibility in the introduction helps predispose the audience to believe you.
  • Sprague et al. (02/2018) describe credibility as a combination of perceived qualities that predispose listeners to believe you.
  • A speaker’s credibility is a blend of perceived qualities from the audience’s first interaction with the speaker up to the present.
  • Examples touched on in the transcript:
  • The speaker’s status (e.g., being an ODU professor) can contribute to perceived credibility.
  • Confidence is a cue, but it can be misleading: outward confidence may mask internal anxiety or worry.
  • Distinction between (a) competency and (b) trustworthiness as core credibility components.
  • In-class moment: the speaker asks if it helps to mention care for students’ grades as part of credibility, then emphasizes the need to maintain order in the introduction.
  • Target guideline: ideally, the introduction should comprise about 10–15% of the speech content.
  • Self-assessment practice moments: students are asked to rate practice on a scale (1–10) and to reflect on recent performance.
  • The discussion frames credibility as a practical, observable set of signals (competence, trust, confi­dence) that influence audience belief.

• Key concepts: Credibility, Egocentric audiences, and Perceived qualities

  • Credibility is built from perceived qualities that predispose belief.
  • Perceived qualities build over time: honesty, competence, confidence, and character cues observed by the audience.
  • Competency and trustworthiness are highlighted as two central pillars.
  • Audience beliefs can be influenced by signals such as professional status and demeanor, but inner state may not always align with outward signals.
  • The introduction as a credibility anchor: if credibility isn’t established early, the message may be discounted.

• Practical implications of audience characteristics

  • Egocentric audiences respond best to evidence that connects to their own interests and needs.
  • Public speakers should foreground credibility early to preempt skepticism.
  • Ethical implication: avoid overstating credentials or misrepresenting expertise; credibility hinges on honesty and consistency over time.

• Strategy for establishing credibility in the introduction

  • Mention relevant credentials and experience briefly but meaningfully (e.g., professorial status).
  • Demonstrate confidence through clear voice, steady posture, and purposeful movement while acknowledging possible internal anxiety.
  • Use credible cues (e.g., demonstration of knowledge, appropriate tone) to create a predisposition to believe the message.
  • Balance with authenticity: do not rely solely on status; substantiate claims with evidence and relevance to the audience.

• Practice and rehearsal: Making practice real

  • Gamble and Gamble (2021) in Public Speaking Playbook:
  • Practice out loud.
  • Practice with notes.
  • Practice with visual aids.
  • Engelberg and Daley (Norton Field Guide to Public Speaking):
  • Practice facial expressions; rehearse overall delivery quality (not just content).
  • Concrete practice recommendations:
  • Use note cards and stand while practicing the text.
  • If using visuals or specific clothing, practice with them; do not memorize them verbatim—rehearse how you will use them in real-time.
  • Core philosophy: practice does not guarantee perfection, but it makes progress.

• Why practice is not about perfection

  • The instructor cautions: do not expect perfection from practice; aim for progress.
  • Acknowledgment of practice realities:
  • Some students may be slower to respond; the instructor may pause or prompt to maintain order and fairness.
  • Nervousness and pacing can affect performance; pauses can help manage delivery and audience perception.
  • The instructor emphasizes that interruptions to allow someone to speak are for fairness and audience perception, not personal offense.
  • Empathy note: misinterpreting pauses or prompts as disrespect can be avoided by explaining the intent (maintain audience engagement and fairness).

• Filler words, distraction, and credibility

  • Filler words cause distraction for the audience.
  • Filler words can decrease perceived credibility because they interrupt flow and signal uncertainty.
  • Goal: minimize filler words to maintain audience engagement and credibility, while recognizing that occasional pauses are natural.

• Practical guidelines for implementing practice in real settings

  • Practice with multiple modalities:
  • Out loud, with and without notes, with visual aids.
  • Attend to facial expressions and body language as part of practice (delivery aesthetics).
  • For the speech text:
  • Use note cards and a podium/stand as you practice;
  • Do not memorize the entire script; rehearse the flow and transitions.
  • When using visuals or wardrobe:
  • Practice the use of visuals and clothing in a rehearsal to prevent interruptions or dependence on memory.

• The “progress, not perfection” mindset

  • Central claim: practice makes progress, not perfection.
  • Reflective prompts used in class:
  • Students evaluate their own practice on a 1–10 scale (e.g., 5 or 6).
  • Some students mention specific performance levels (e.g., B-], C+]) to anchor feedback.
  • The instructor’s goal is to advance readiness rather than demanding flawless execution in practice.

• Classroom dynamics and time management during speaking exercises

  • Instructors may guide speakers by asking for readiness and prompting when necessary to ensure everyone has a fair chance to speak.
  • If the instructor pauses, it is to help students gather thoughts and ensure audience engagement, not to dismiss or demean students.
  • Expressions of apology or clarification may be offered when the pacing affects confidence or perceived fairness.
  • The closing action in the transcript: a transition to the next topic with a brief apology for any offense caused by the pacing, emphasizing fairness and focus.

• Connections to foundational principles and real-world relevance

  • Credibility, audience analysis, and message framing are foundational to effective public speaking.
  • The discussion ties into general communication theory: audience predispositions and perceived credibility shape how messages are received.
  • Real-world relevance includes classroom presentations, professional talks, and any scenario where first impressions influence persuasion.

• Notable formulas and numerical references

  • Introduction length guidance as a proportion of total speech length:
    $L<em>{ ext{intro}} = p \, L</em>{ ext{total}}, \, \quad p \in [0.1, 0.15]$
  • Self-assessment scales referenced in class:
  • Practice readiness on a scale from 1 to 10 (e.g., 5 or 6).
  • Acknowledgment of concrete numbers and qualitative descriptors used in feedback (e.g., C+, B-, six classes, six sessions).

• Ethical, philosophical, and practical implications

  • Ethical: avoid misrepresenting credentials; credibility should be earned through honest, demonstrated competence and trustworthiness.
  • Practical: early emphasis on credibility can reduce audience resistance and improve engagement.
  • Philosophical: the balance between outward signals (confidence) and inner state (anxiety) highlights the complexity of authenticity in performance.

• Summary takeaways

  • The introduction is critical for capturing attention and establishing credibility with an egocentric audience.
  • Credibility consists of perceived competence and trustworthiness; signals from status, confidence, and consistency matter.
  • Practice is essential, but perfection is not the goal; progress through varied practice methods strengthens delivery.
  • Minimize filler words and rehearse with notes, visuals, and appropriate pacing to sustain audience trust and engagement.
  • Classroom dynamics around pacing and fairness aim to support all students toward improvement.

• Quick reference checklist for preparing an introduction

  • Clarify the attention-getter aligned with audience needs.
  • Briefly establish credibility (status, competence cues) without overpromising.
  • Keep the introduction to about $L<em>{ ext{intro}} = p \cdot L</em>{ ext{total}}, \quad p \in [0.1, 0.15]$ of total length.
  • Practice out loud with notes and visuals; rehearse facial expressions and body language.
  • Use note cards and stand; avoid memorization of the entire text; rehearse practicality with visuals/attire.
  • Monitor filler words and pacing; allow occasional deliberate pauses for clarity and emphasis.
  • Seek feedback and reflect on self-assessed practice scores (e.g., 5–6 on a 1–10 scale) to guide improvement.
