an  explicit  instruction  to  remember  the  facts  vs.  not  being  told  to  remember  had  no  impact  on
            participants’ rates of recall. This finding, dubbed by the authors as the “Google Effect,” and later
            referred to by other researchers as “digital amnesia” (Kaspersky Lab, 2015) demonstrates that the
            expectation of having later access to information can make us less inclined to encode and store that
            information in long-term memory.
            Sparrow  et  al.  (2011)
            further argued that we are
            becoming  symbiotic  with
            our            technology;
            remembering  less  actual
            information  and  instead
            committing  to  memory
            where  such  information
            can  be  found.  To  further
            investigate this theory, the
            researchers  conducted  an
            additional     experiment
            using a design similar to that described above, but with three within-subject conditions. For one
            third of the questions, participants were simply told that the information they entered was saved.
            Another third of the questions resulted in the participants being told that the information was saved
            into  one  of  six  pre-determined  folders  (named  FACTS,  DATA,  INFO,  NAMES,  ITEMS,  and
            POINTS).  The  remaining  third  of  the  questions  were  followed  by  a  prompt  that  informed  the
            participants that the information they typed was immediately deleted. The results of this experiment
            indicated that participants were better able to recall the name of the folder in which the relevant
            information was located than the information itself. The authors use this finding to claim that, “the
            processes  of  human  memory  are  adapting  to  the  advent  of  new  computing  and  communication
            technology” (Sparrow et al., 2011, p. 778). A potential experimental confound that Sparrow et al.
            do not discuss is the amount of “information”  represented by the trivia fact vs. the name of the
            folder. The authors provide an example fact, “The space shuttle Columbia disintegrated during re-
            entry over Texas in February 2003.”
            The complexity of the fact may make it more difficult to memorize than the name of the folder in
            which  the  information  is  stored  (i.e.,  FACTS).  Future  research  should  attempt  to  create  more
            balance between the trivia statements and the folder names.
            Barr  et  al.  (2015)  recently  reported  findings  from  a  further  exploration  of  internet  access  via
            smartphones and knowledge representation. In keeping with the notion that humans are generally
            “cognitive  misers”  (Kahneman,  2011),  these  authors  posited  that  the  tendency  to  rely  on  simple
            heuristics and mental shortcuts extends to the habitual use of internet search engines as a substitute
            for  deep  cognitive  analysis.  In  their  experiment,  Barr  et  al.  (2015)  gave  participants  a  series  of
            cognitively demanding questions, including syllogisms, base-rate problems, and a “heuristics and
            biases” battery. They also assessed participants’ knowledge in different cognitive domains through
            administration  of  a  numeracy  test  and  a  verbal  i  ntelligence  test.  Finally,  participants  were  also
            asked to provide an estimation of how much time per day they spend on their smartphones overall,
            as well as an estimation of how much time they spend specifically using internet search engines on
            their  smartphones.  The  results  showed  that  individuals  who  reported  being  heavy  users  of
