In British English, we would use the present perfect to discuss actions that have taken place in the recent past and are complete or have a continuing effect in the present. Set phrases such as "the past year/month/week" refer to periods of time which have continued to the present time. Thus we would tend to say things like "This past week I have been reading crime novels".

Americans don't tend to care so much about the present perfect and frequently use the simple past.
