• Tutors and tutees share a similar "knowledge framework"

• Tutors can identify where their tutee is struggling and what topics their tutee will consider being easy and/or difficult

• Tutors use familiar language with tutees - informal communication is associated with efficient knowledge transfer

• All of this helps tutors explain difficult concepts to tutees

• Creates a less stressful, more relaxed and informal environment/climate

• Informal communication and a nonjudgmental learning climate are more associated with cognitive congruence than social congruence
