Moral reminder Sepuluh Perintah Tuhan telah diuji dapat mengurangi perilaku tidak etis secara signifikan walaupun individu mendapat godaan untuk berperilaku tidak etis. Godaan tersebut tidak akan berpengaruh apabila individu memiliki perhatian penuh terhadap standar moralnya dan internal reward mechanism yang berfungsi dengan baik melalui pemberian moral reminder. Pada penelitian ini, penulis hendak menguji kembali pengaruh moral reminder Sepuluh Perintah Tuhan terhadap perilaku tidak etis pada siswa kelas 3 SMA yang beragama Nasrani. Hasil uji statistik independent sample t-test menunjukkan bahwa partisipan yang diberikan moral reminder melalui tugas menulis Sepuluh Perintah Tuhan memiliki rata-rata ketidakjujuran lebih tinggi M = 0,24; SD = 0,60 dibandingkan partisipan yang tidak diberikan moral reminder dengan tugas menulis sepuluh judul film M = 0,05; SD = 0,28. Perbedaan mean tidak signifikan, t 58,64 = 1,98 ; p > 0,05. Akibatnya, siswa tetap berperilaku tidak jujur saat melaporkan skor jawaban pada eksperimenter meskipun diberikan moral reminder Sepuluh Perintah Tuhan. Hal itu terjadi karena moral reminder hanya meningkatkan atensi partisipan terhadap standar moralnya, tetapi internal reward mechanism tidak berfungsi dengan baik.

Moral reminder the Ten Commandments been tested could reduce unethical behavior significantly although individual received the temptation to behave unethical. The temptation would not affect if individual having full attention towards moral standard and internal reward mechanism functioning well through the provision of moral reminder. In this research, the writer is about to examine more the moral reminder 'Ten Commandments' on the students of 3rd grade of high school whose religion is Christian.

The result of the independent sample t test has shown that the participants who were given moral reminder by having 'Ten Commandments' task have the higher level of dishonesty M 0,24 SD 0,60 compared with those who were not with the task writing 10 names of movies M 0,05 SD 0,28 . The difference of mean was not significant is t 58,64 1,98 p 0,05. As the consequence, students are still being dishonest during reporting their results to the experimentalist even though they were given moral reminder. This is because moral reminder just increased participant attention towards moral standard, but internal reward mechanism did not function properly.
