We have realized the experiment as a form of a social – psychological training (SPT) with university students – future teachers (140 participants). Their average age was 22.3 years. We have tried to find out the influence of SPT on a group atmosphere of a trained group based on the comparison of continuous and block forms of training. The experimental group was made up of 69 participants divided into four smaller groups (EG1 – EG4) to which SPT has been implemented in 96 hours appropriations. A continuous form of training has been implemented in EG 1 –EG 2 and a block form of training has been implemented in EG 3-EG 4. The control group was made up of 71 participants divided into four smaller groups without SPT implementation. After the SPT we have found out that SPT has improved a group atmosphere by using A Group Atmosphere Scale. Both forms of SPT had similarly significant influence on a group atmosphere.
