What makes you think so?  Variables are always visible in invoked
functions, unless you shadow them using local/declare/typeset.

        % cat /tmp/foo.bash; echo
        function my_function(){
            declare -A my_array
            my_array=(["one"]="one")
            other_function
        }

        function other_function(){
            echo "${my_array["one"]}"
        }

        my_function

        % bash /tmp/foo.bash
        one
