The elements of the Human Interaction Laboratory (HI Lab) include:

  • Self-Awareness
  • Emotional Intelligence Diversity, Equity, Inclusion, and Belonging
  • Group Dynamics
  • Authenticity in Relationships
  • Deep Listening
  • Giving and Receiving Feedback Effectively
  • Leadership Effectiveness
  • Experiential Methodology of T-Group Work
  • Understanding use of self and our impact on others

This signature program of NTL Institute develops the key areas of personal and leadership effectiveness: self-awareness, interpersonal skills and ability to observe and be facilitative in a group. In real-time situations, you will learn how your own behavior impacts others. You will learn to give and receive feedback in a way that creates connections and learning for others and yourself. Through this process you will learn to make the changes you need to make to achieve the results you desire.

Past participants report that after the HI Lab they are able to communicate more effectively with co-workers, colleagues, clients, and family members and that this learning "sticks" over time.

The HI Lab of today is as impactful- even life-changing - as it has evolved over 60 years, supported by conceptual and in-the-moment semi-structured learning sessions. It also uses the principles of emotional intelligence - the ability to identify emotions (in both yourself and others) - to realize the powerful effects of those emotions, and to apply that information to guide behavior.

The core methodology for NTL's HI Lab is the T-Group, or Training Group, which is a type of experience-based learning in which participants work together in a small group of 8-14 people, over an extended period. Learning comes through analysis of their own experiences and interactions, including feelings, reactions, perceptions, and behavior. T-Group provides a setting in which people are encouraged to experiment with new behaviors, examine their experiences in light of feedback from others, and consider what range of behavior changes to consider. 

Underlying Assumptions

Underlying the T-Group are the following assumptions about the nature of the process which distinguish T-Groups from other more traditional models of learning:

  • LEARNING RESPONSIBILITY. Participants take responsibility for their own learning as well as contributing to others' learning. What people learn depends upon their own style, readiness, and the relationship they develop with other members of the group.
  • AUTHENTIC RELATIONSHIPS and LEARNING. People are most free to learn when they establish authentic relationships  in which they can be open, honest, and direct with one another so that they are communicating what they are actually feeling rather than masking their feelings.
  • Many people report that they try out behavior in the T-Group that they have never tried before. This experimentation can enlarge their view of their own potential and competence and provide the basis for continuing experimentation.
  • SKILL ACQUISITION and BEHAVIOR CHANGE. The development of new skills in working with people is maximized as participants examine the basic values underlying their behavior, learn and apply appropriate concepts and theory, practice new behavior, and obtain feedback on the degree to which the behavior produces the intended impact.
  • STAFF ROLE: The staff person's role is to facilitate the group in creating a climate supportive of learning where the desired learning process and outcomes are actualized. Diverse staff teams are drawn from NTL members with training and expertise in this area.

I came in with anticipation and nervousness about the unknown - I left with understanding, and a quantity of positive emotions and feelings, lifelong friendships, and an eagerness to continue learning. There's a vast array of information and tools to enhance leadership skills. Thank you!

I am new to experiential learning. I came to NTL's Human Interaction Lab with high hopes and expectations, both personally and professionally. These were far surpassed, and what I experienced was profound. I believe it important to conclude this survey as I began the experience: fully engaged and invested in new and dynamic dimensions of growth.

I got a lot out of this experience and grew tremendously as a person. The group process work is amazing and powerful.

I came in anxious and unsure about the process and what I would take away. Now I'm committed to continued personal growth. Thank you for providing this transformative experience!
