Notes on Barriers to Communication, Writing, and Presentations

Perceptual Barriers and Biases

Perceptual barriers arise when we prematurely judge others based on appearance, speech, dress, or skin color, which closes us off from open dialogue. The speaker emphasizes that if we perceive someone as “other,” we’re less likely to engage or value what they have to say. This is illustrated with a scenario where a person might dismiss an officer or superior because of perceived differences, creating a barrier in the conversation. The overarching idea is that our own identity—what we look like, how we sound, and how we present ourselves—shapes what we deem valuable in others, and this in turn affects communication, listening, and collaboration.

A practical example is a business meeting: if a junior employee is perceived as rude, the other party may form a negative impression and resist future engagement. The same dynamic applies across cultures and organizations, where time is a precious resource and the hierarchy can amplify the impact of initial impressions. In a military context, the notion of who has “something worth saying” becomes even more pronounced due to chain-of-command dynamics, where a message may need to travel up through several layers before it’s acknowledged or acted upon. The key point is that perceptual barriers, when combined with bias, can prevent useful information from reaching the right decision-maker.

Ethical and practical implications surface when biases hinder fair treatment or access to opportunities. The speaker notes that in business, bias can lead to negative outcomes if it informs who an organization chooses to work with, or whom it respects and listens to. This ties into broader questions about equity and the responsible exercise of power within organizations. The idea is to recognize and mitigate perceptual barriers so conversations can be inclusive and productive rather than exclusionary.

Organizational and Physical Barriers

Organizations often implement barriers to protect time and efficiency. The speaker describes a common pattern: information or requests flow through a chain of command, from an entry-level employee up to executives. The premise is that an entry-level worker typically lacks the time or relevance to speak directly with a CEO, so hierarchies help triage messages and protect the CEO’s time. This is presented as a deliberate, efficiency-driven structure rather than a mere wall between people. Yet barriers are not inherently negative; they can streamline workflows by ensuring that concerns are forwarded through appropriate channels.

However, barriers can also impede rapid problem-solving when something urgent arises. The speaker highlights that these organizational barriers interact with other barriers—time, attention, and resource constraints—creating a complex network that can hamper communication if not managed properly. The takeaway is to understand when and why to use barriers to improve efficiency, while staying open to bypassing them when necessary to address urgent issues.

Physically, the environment introduces tangible barriers. Examples include auditory barriers like a projector’s hum raising background noise, or the need to adjust volume for participants at the back or those seated near loud equipment. Distance and seating arrangements can affect how clearly a message is received, and temperature or comfort levels (e.g., a room that’s cold in the morning) can distract listeners. The speaker points out that simply “turning up the volume” won’t fix all physical barriers; solutions must consider spatial layout, acoustics, and comfort so everyone can engage effectively.

The three-step process to diagnose and fix barriers is recurring throughout the talk: first identify the noise, then identify the barrier the noise creates, and finally discuss and implement fixes. This approach applies to both physical and perceptual barriers, recognizing that different people experience different barriers based on their position, perception, and environment. The goal is to align the room’s conditions and the conversation’s conduct so that the barrier does not derail understanding.

Linguistic and Cultural Barriers

Language diversity is another major barrier. The speaker cites a context with Mexico and references “over a hundred languages,” along with dialectal differences that can complicate mutual comprehension. The broader point is that even within the same language family, regional variations (dialects, slang, formal vs. informal registers) can produce miscommunication. For example, Castilian Spanish versus Puerto Rican Spanish may carry distinct pronunciations, vocabularies, or rhythms that require sensitivity and adaptation in dialogue.

In cross-cultural settings, mediated communication styles can differ. What is considered direct or polite in one culture might be perceived as abrupt or disrespectful in another. Recognizing these differences is essential to avoiding misinterpretation and ensuring messages are received as intended. The speaker underscores that language and cultural differences can create substantial barriers if not acknowledged and navigated with cultural competence.

Physical Environment and Proxemics

Environmental factors contribute to communication barriers. The example of sitting under a projector with a humming sound illustrates how minor sensory annoyances can distract listeners and reduce engagement. Physical proximity and seating arrangements affect who is heard and who is left out of the conversation. The speaker also notes the impact of temperature and comfort: if a room is too cold or too hot, some participants will be uncomfortable and distracted, which diminishes message processing.

It’s important to identify these noise sources and discuss how to adjust the setting so that the message can be received clearly by all participants. This means addressing acoustic issues, seating visibility, and comfort rather than merely telling people to speak louder. A holistic approach to physical barriers considers lighting, sound, temperature, and seating to maintain a conducive learning and working environment.

Nonverbal Communication, Tone, and Perception

Nonverbal cues such as body language, facial expressions, and tone can communicate far more than words and can either reinforce or contradict spoken messages. The speaker confesses that their body language and facial expressions (for example, rolling eyes or a dismissive gesture) can be interpreted as condescending or disrespectful, even when their words are neutral or friendly. This mismatch between spoken content and nonverbal signals can erode trust and escalate conflict.

Listeners also bring their own interpretations to nonverbal cues, which means misreadings are common. The speaker reflects on their own tendencies to display skepticism or sarcasm nonverbally when they doubt what someone says, and acknowledges that others may perceive this as contempt. The ethical implication is to be mindful of how facial expressions, gestures, and tone may be read by others, and to align nonverbal signals with verbal messages to maintain respect and clarity in communication.

Active Listening, Note-Taking, and Engagement in Class

Active listening is framed as essential for effective communication. The speaker encourages students to take “canned notes”—structured notes that demonstrate active listening and engagement. The practice of asking questions and seeking clarification is promoted as a way to keep conversations dynamic and meaningful.

Practical channels for communication are discussed: email via Outlook (as the recommended official channel) or in-person communication. Canvas is mentioned less favorably for certain interactions. If a student will miss a class, the instructor requests advance notification via email, not after the fact. Emails serve as documentation to protect both parties and specify plans to make up examinations or assignments.

The speaker emphasizes professional boundaries and the importance of documenting communication to avoid future confusion. There is also a candid note about the instructor’s preferences and boundaries, including the need to adapt the teaching style for different cohorts (e.g., younger students versus peers). Humor and informal interactions are used to build rapport, but the underlying message is to maintain respectful, clear communication and to document it when possible.

Bias, Ethics, and Professional Conduct in Business and Academia

Bias—whether related to gender, age, appearance, or background—has practical and ethical consequences in professional settings. The speaker notes that gender protections and law exist to prevent discrimination in workplaces, and that bias can have real, negative repercussions when it affects who a business chooses to work with. The idea is to practice fairness in communication and decisions, recognizing that bias can undermine trust and productivity.

The talk also touches on the tension between free trade and personal biases. While free trade allows individuals and organizations to choose partners, actions founded on bias can damage reputations and relationships, and may lead to legal or social consequences. The ethical takeaway is to strive for inclusivity and fairness in communication and business practices, while being mindful of personal prejudices and their impact on others.

Paper, Presentation, and Exam Writing Guidelines

When preparing papers, presentations, or exams, the instructor discourages run-on paragraphs. The standard expectation is that each exam question should be addressed with at least $2$ paragraphs; writing a single, long paragraph that mixes multiple points is discouraged because it obscures structure and clarity. The organization should mirror the intended structure of the assignment: multiple distinct points should appear in separate, well-formed paragraphs.

Students are advised not to rely on reading a paper verbatim during a presentation. The aim is to convey the same sentiment and content in a natural, conversational way while maintaining coherence with the written piece. The professor endorses outlining and drafting with a focus on APA formatting, though students can also submit draft versions to the Writing Center for feedback. The Writing Center offers online and in-person services, including a markup sheet to document attendance and feedback when submitting work through Canvas.

Regarding content versus form, the instructor emphasizes that grading will focus more on structure, paragraphing, APA formatting, and length rather than the originality of ideas. Students are encouraged to seek feedback to improve formal writing, and nervousness should not be used as a reason to lower scores. The overall message is to develop professional writing habits and use institutional resources to improve quality.

Writing Center Resources and APA Formatting

The Writing Center is a valuable resource for improving academic writing. It offers online services (email-submitted papers with feedback) and virtual consultations. To receive credit for using the service, students should attach the consultant’s markup sheet to their submitted paper as evidence of attendance and feedback. While instructors may differ in tolerance for content quality, there is broad support for using the Writing Center to ensure adherence to APA formatting, proper paragraph structure, and appropriate length.

The instructor notes that even as a professor with strong business writing experience, they still rely on the Writing Center to polish academic writing. This demonstrates a practical, ongoing commitment to high-quality writing, and reinforces the value of seeking external feedback for improvement. Students are encouraged to prepare with the Writing Center early and often rather than waiting until the last minute.

Presentations: Timing, Execution, and Scoring Rubric

Presentations are time-managed with a practical target of roughly $5$ minutes. A strict policy applies: exceeding the allotted time can incur point deductions, and going significantly over is not permitted. If a student finishes early or runs through the material quickly (e.g., finishing in around $1$-$2$ minutes), the instructor may ask questions to re-engage and extend the discussion. Conversely, finishing too early without engagement could reduce points, so pacing and content are important.

Judging criteria focus on time compliance, clarity, delivery, and engagement. The instructor warns against wearing inappropriate attire (sweatpants, shorts, pajama-like outfits) and emphasizes presenting in a professional manner. The use of natural gestures is recommended, avoiding exaggerated or distracting movements. If a student deviates from the plan (e.g., rushing through the speech due to nerves), the instructor will intervene to guide the discussion and help the student regain control of the presentation.

A practical framework (referred to as a matrix) guides expectations: be close to the target time, maintain a presentable appearance, and ensure content is delivered with a coherent structure. If a student encounters nerves or fatigue, the instructor offers support to help them stay on track, but the core requirement remains time management, organization, and professional conduct. Practice and preparation are highlighted as essential components of a successful presentation.

Practical Tips: Delivery, Gesture, and Preparation

Throughout the talk, several practical recommendations emerge for both written and oral communication:

• Use clear structure: separate ideas into distinct paragraphs and ensure logical flow between sections.
• Practice to manage time and delivery, aiming for the target window (about $5$ minutes) but staying flexible to respond to audience needs.
• Employ natural, purposeful gestures that support your message rather than distract from it.
• Prepare for environmental factors: adjust volume for listeners at the back, consider room acoustics, and maintain comfort for all participants.
• Embrace feedback and use institutional resources (Writing Center, peer reviews) to strengthen both writing and speaking skills.
• Maintain professional communication channels (Outlook email for formal communication, in-person or appropriate channels for immediate concerns) and document essential interactions to protect both parties.

References to Real-World Relevance and Ethics

The discussion points connect classroom practices to real-world professional contexts. Recognizing and addressing barriers—perceptual, organizational, linguistic, or physical—translates into more effective teamwork, better customer or client relations, and more equitable workplaces. The ethical emphasis on avoiding condescension, respectful tone, and awareness of bias reflects core professional standards that extend beyond academia. The balance between efficiency (through barriers) and inclusivity (through open communication) mirrors the tensions many organizations face when designing processes and policies.
