Boosting Your Interpersonal Skills: Getting an Edge Over the Competition

Despite the crucial role they play, interpersonal skills often remain unpolished in many individuals’ repertoire. Why not turn this widespread oversight into your personal advantage?

By investing time in upgrading your interpersonal skills, you can stand out in a crowd where competition is surprisingly weak.

Let’s dive into how you can leapfrog your peers and make a lasting impression through refined interpersonal communication.

Interpersonal skills are a key element of our success in life. There are six major ones that can make a real difference in how well we work with others.

What is Two-Way Communication?

Two-way communication is a process in which two or more people exchange information and ideas. Unlike one-way communication, you FEEDBACK is available so one can see and hear how well your message is being received and understood.

Because feedback is near real-time, the sender can adjustments their message to enhance both impact and understanding.

What Are The Benefits of Two-Way Communication

  • Improved understanding: Two-way communication helps to ensure that both parties understand each other’s message. This is important for building trust and rapport.
  • Increased collaboration: Two-way communication allows for the exchange of ideas and feedback. This can lead to better decision-making and problem-solving.
  • Enhanced problem-solving: It helps to identify and resolve problems more quickly and effectively.
  • Improved employee morale: Two-way communication can help to create a more positive and productive work environment.

The Elements of the Two-Way Communication Model

Understanding the key components of both one-way and two-way communication models is essential for enhancing your communication abilities. Let’s explore how these models work, and how you, as a sender or a receiver, can effectively use each model to communicate your thoughts and ideas.

The one-way and two way communication model
The one-way and two-way communication model. It looks easy but is subject to all sorts of barriers leading to misunderstanding.

The Sender. The genesis of any communication is the sender, an individual, group, or organization with a message they wish to share. This message undergoes a process called encoding, where thoughts are transformed into language – a process often invisible to the naked eye, yet crucial for effective communication.

The Receiver. The receiver, in contrast, is the entity that interprets the encoded message. This could be you when you’re listening to a speaker or reading a text. Just as with encoding, decoding – the act of converting language back into thought – is a subtle yet critical process.

Encoding and Decoding. To transfer a message, the sender employs a series of symbols representing various concepts. During decoding, the receiver then translates these symbols back into meaningful concepts and ideas.

Choosing the Right Medium. Every sender must select an appropriate communication medium. Traditional communication mediums fall into three categories: written, verbal, and electronic. The choice of medium depends on the nature of the message and the intended audience.

Interference (or Noise). Interference, often termed as ‘noise’, refers to any disruption or hindrance during the communication process. This could be anything from environmental noise to personal biases that prevent effective listening or comprehension.

Feedback. Feedback is the receiver’s reaction to the message. In two-way communication, this feedback is actively shared with the sender. However, in one-way communication, feedback is usually absent, leaving the sender without direct insights into the receiver’s understanding or reaction.

The Full Duplex Technique — The Key to Effective Two-way Communication

Full-Duplex is a term borrowed from telecommunication technology. It means that as a sender, you send verbal information and receive nonverbal cues simultaneously. So as a speaker, your goal is to pay attention to both the receiver’s words (if any) and their nonverbal signals. 

We do this to get more meaning from the other’s nonverbals. For example, doing so allows you to determine whether the other person understands you or not.

Would you know what I mean by saying, “Meet me at the Hollis”? Of course, most of us would say no. However, if I were a sender with excellent interpersonal communication skills, I would see that you were confused over the word “Hollis” and then take steps to clarify.

If you can read face, you have a significant advantage over those that can’t. I used to routinely do this every morning with my bosses since I wanted to know what mood they were in. I happened to have terrific bosses, but every once in a while, they could bite the neck off an alligator. Should such a rare event occur, it was best to say hello, beat a hasty retreat, and hide.

Pitfalls of One-Way Communication

Charles Joshua Chaplin (1825–1891): A Conversation Overheard

One-way communication is essentially a flawed communication model when compared to the two-way approach. Essentially, what makes this a problem is the reduced availability of feedback, likely leading to misunderstanding. Sometimes this occurs face to face. But it also occurs in written and electronic communication.

The Perils of Misinterpretation in Writing

One-way communication is often implicated in written exchanges where feedback is either delayed or entirely absent. Consider an email – you send one to a friend, but unless you follow up, you might never know if it was opened, read, or even remembered. This uncertainty fosters fertile ground for misunderstandings.

It’s noteworthy to mention the phenomenon of “scholarly English,” a version of the language wielded by academics writing for scholarly journals. These pieces, notorious for their intricate language and complex structures, have been humorously dubbed as ‘insomnia cures,’ highlighting the potential obscurity in one-way written communication.

The Enigma of Electronic Media

The advent of digital technology has introduced new dimensions to one-way communication. Platforms like social media allow interaction, but the feedback remains limited. For instance, you might post a status update on your Facebook page for your 300 ‘friends.’ If only five ‘like’ it and one comments, what does it mean for the rest? Possibly, the remaining 295 didn’t favor your post, and 299 found it pointless, but opted to stay silent.

Even in this digital age, electronic media often lack the immediacy of feedback. However, certain cues, such as a callback in response to a message, can verify whether the communication was effectively understood.

Improving Your Two-Way Communication Skills

Two-way communication shines as the preferred model for most interactions, thanks to its dynamic and responsive nature. It demands simultaneous processing of verbal and nonverbal cues, fostering a deeper, more accurate understanding between the sender and receiver.

Quote: How well we communicate is determined not by how well we say things, but by how well we are understood. — Andrew Grove


  • Be an active listener: When someone is speaking to you, give them your full attention. Make eye contact, nod your head, and ask clarifying questions.
  • Be open to feedback: Don’t be defensive when someone gives you feedback. Instead, listen carefully and try to see things from their perspective.

Mastering Two-Way Communication with The Full-Duplex Approach

The Sender’s Role in Full-Duplex Communication. The concept of Full-Duplex, borrowed from communication technology, paints the perfect picture of effective two-way communication. It implies that as a sender, you should be transmitting and receiving information simultaneously. This means, while speaking, you should also observe the receiver’s verbal and nonverbal responses.

Practicing this attentive interaction allows you to glean more meaning from the other person’s nonverbal cues. For instance, if you notice a look of confusion when you say, “Meet me at the Hollis,” a competent communicator would immediately clarify. This nuanced reading of faces gives you an edge over those who miss such cues.

The Receiver’s Role: Active Listening. Active listening is the receiver’s equivalent of Full-Duplex communication. It involves maintaining eye contact, nodding to show understanding, and asking questions for further clarity.

Two-Way Communication Mediums (There are Only Three)

The Telephone. While a traditional phone call enables real-time dialogue, it lacks visual nonverbal feedback. However, modern technology, like computer and mobile cameras, are bridging this gap.

Face-to-Face Communication. Considered the gold standard of two-way communication, face-to-face interaction is unparalleled when it comes to sensitive conversations. The rich blend of verbal and nonverbal cues it provides makes it the preferred method for any crucial dialogue.

Video Conferencing. Next to face-to-face, this is the best channel to use. It overcomes the major problem with the telephone — lack of visual feedback and is a real time as you can get. While one is missing nonverbal gestures, you should be able to picture up nonverbal facial feedback if you pay attention to it.

Three Real-World Applications

Interviews. Interviews serve as a perfect arena to demonstrate two-way communication. By attentively reading the interviewer’s facial expressions and gestures, you can tailor your answers to align with their expectations, significantly increasing your chances of success.

Conversations with the Boss. Regular interactions with your boss, whether professional or casual, provide excellent opportunities to utilize two-way communication. For instance, casual small talk may not demand stringent monitoring of nonverbal cues. However, when you’re pitching an idea in their office, picking up on their nonverbal signals could provide valuable insight into their thoughts and reactions.

Coaching Sessions. Two-way communication skills shine in coaching or counseling scenarios. The ability to detect confusion or misunderstanding from nonverbal cues can immensely benefit the learning process. Hence, monitoring these nonverbal signals is crucial to facilitating effective skill-building sessions.


In a world where clear, impactful communication often determines success, understanding the dynamics of one-way and two-way communication is key. While each model has its place, two-way communication invariably facilitates a more nuanced and effective exchange. It involves a constant interplay of sending and receiving messages, of reading and responding to verbal and nonverbal cues. Whether it’s for a crucial job interview, a persuasive pitch to your boss, or a coaching session, practicing and honing your two-way communication skills can significantly enhance your interpersonal relationships and professional prospects.
