Psychopsis normally shed their old leaves and leave behind bare pseudobulbs. That is nature, you can't change that.
Plants in general are what are considered "plastic", and will adjust their growth to what their environment is like. If it is growing smaller, it probably is related to three things - light, nutrients, or water.
Insufficient water usually means buckled leaves and/or smaller growths.
Bright light can also affect the size of the growths. If they are getting the maximum amount of light they can tolerate without burning, the next subsequent growths may be smaller.
An insufficient amount of nutrients could also be a determining factor in how large or small the subsequent growths are. Make sure you fertilize on a regular basis.
It's difficult to know which factors are affecting your plant without a picture, and even when provided a photo, it can be tricky to diagnose what the problem(s) could be. There is some trial and error to be done sometimes, in order to figure things out.
