First off, thank you to everyone who stepped up to help me with this question. So I followed the advice that was given and wrote a little test script which went something like this: 
my @array;
my %hash;

&callaFunction();
&callaFunction();
&callaFunction();

foreach my $element ( @array ) {
  my %localHash = %{$element};
  # print %localHash's contents
}

sub callaFunction {
  # fill %hash with random info
  push ( @array, {%hash} );
}

And this script worked perfectly well. Each index of the array was unique (as opposed to if I made calls to push @array, %hash; in which case every index of the array contained a reference to the same hash, with whatever values were put in the hash last).

However, when, armed with this newfound knowledge, I sallied forth into my main program and applied what I had learned, I was thoroughly vexed to find that my original problem had once again reared its ugly head! That is to say, although I called 

push ( @globalArray, {%globalHash} );

I found that each element of @globalArray had the same values within it. So somehow, although I created anonymous hashes to push onto the array, a single reference to the same hash was pushed onto the array again and again.

Monks, I am at a loss. The inner magics of references are but newly known to me. So my question to you, O monks whose wisdom shines like a stream of bat urine on a moonlit night, is this: how could the call to push which I describe above still result in the same reference being pushed onto my array repeatedly?

Some people drink from the fountain of knowledge, others just gargle.
