Final answer:
A medical laboratory scientist can use open gestures and maintain eye contact for effective communication. Closed-off body language and fidgeting should be avoided. Speaking rapidly and avoiding pauses can also hinder effective communication.
Step-by-step explanation:
A medical laboratory scientist can use open gestures and maintain eye contact for effective communication. Open gestures, such as open palms and relaxed body posture, convey openness and friendliness. Maintaining eye contact shows engagement and attentiveness.
On the other hand, closed-off body language, such as crossed arms and avoiding eye contact, can create barriers in communication and make the person appear unapproachable or disinterested.
Fidgeting and erratic movements can be distracting and may convey nervousness or lack of confidence, which can negatively impact communication. Speaking rapidly and avoiding pauses may result in unclear communication as the person may not give others a chance to respond or understand the information being conveyed.
