　　代沟，简单地说就是不同年龄层次的人因思想观念上的差距造成的心理距离。就象沟一样，隔开了一代一代的人，影响两代人之间的理解和沟通。但是到了新世纪，代沟不仅存在于上一代与下一代之间，而且在年龄相隔10年、8年的人们之间，甚至在大学的高年级与低年级之间，都会有令人惊叹的明显差异。人们常常说，代沟是时间的痕迹，变革的脚步。如此看来，出现代沟是自然的，没有代沟反倒是不自然的，所以，代沟现象也容易被人理解。 但代沟毕竟是困扰交流与沟通的难点，而且容易增加形成偏见和歧视的可能性，代沟两侧的人轻则互不理解，重则抱有敌意，所以我们也要通过种种途径作各种努力来跨越代沟、填平代沟。其实，代沟也并不是一种物理存在，而是一种心理存在，接触，可以让代与代之间曾经断裂的心理联系接续起来，从而达到交流的顺畅和相处的和谐。

　　承代沟的客观存在，心平气和地对待代沟，这样不仅有助于自己，也有益于他人。

　　代沟往往是心理认识的偏差导致的。人们选择信息角度的不同，决定了有人着眼于变化和差异，有人着眼于不变和相似。所以人们不能接受上代或下代与自己这一代人的差异，往往与知性的选择性有关。
