Differences in perspective differ from person to person, group to group and society to society, so it is almost impossible to generalize and talk about "perspectives of Spaniards" or "perspectives of Americans." I can, however, speak to the different perspectives that I have encountered in my personal experiences and these could perhaps be familiar to at least some other people!
Just the other day, my brother asked me if he thought that speaking Spanish makes people think differently. He wondered if the language you think about a problem in affects how you handle that problem. I pondered that idea for a while until I finally thought of an example. If someone bumps a table and a glass of milk falls off the table, in English we might say, "She knocked the glass off the table." In Spanish, people might say, "Se le cayó la taza." This sentence is about the person knocking the glass off the table, instead it is about the glass falling off the table. Less blame is placed on the person in that way.
Similarly, if someone forgets something in English we tend to say, "I forgot." In Spanish, it isn't uncommon to hear, "Se me olvidó." which is more comparable to "It slipped my mind." Again, there is less blame placed on the person and more place on the object or the circumstances.
