May I Have Your Attention Please

Cognitive interviews are often preferred because of the explicit information attained. An interviewer will typically focus on temporal and spatial questions to elicit this information. So, once your interviewee’s descriptive verbiage begins, how do you know if you are receiving completely accurate information?
Ramp up the cognitive load and the verbal and nonverbal deceptive cues will emerge! Whoa, not so fast. What if your interviewee is completely comfortable telling tall tales? Requesting temporal and spatial details may not trigger extra cognitive load. They may rely on

established schema or rehearsed scenarios to dilute the effects of extra mental strain.
However, splitting their attention may do the trick. Diverge from maintaining eye contact and flip flop around with questions that do not seem to follow a normal sequence. This split-attention effect will make relying on schema more difficult and “new” scenarios will need to be created, for those interviewees with deceptive tendencies. In turn, cognitive load will be induced and deceptive cues will emerge.
What about interviewees telling the truth? This technique will also induce mental strain, but most truth tellers usually respond to cognitive load with less descriptive and shorter answers. If they receive positive feedback from the interviewer, the cognitive load will also be lessened. Unlike the deceptive interviewee, the truthful interviewee is not pressured to monitor feedback, verbiage, and possible deceptive cues.

Memories of the Future

Coined by David Ingvar, memories of the future, refers to our intentions.   As proactive beings, we make plans and follow them to guide our behavior.  While gathering snippets of our past experiences, we try to anticipate outcomes of possible future actions.  Therefore, we depend on these schemas to direct our actions, resulting in desired behavioral outcomes that do not imitate past experiences or present realities.

The general consensus has been that deceptive behavior is more cognitively demanding than truthful behavior.  However, more recent research is pointing to truthful intent as more cognitively demanding than false intent.  How so? You may ask.  Conceptualizing truthful intent requires not only planning for the future but also recalling memories of past actions and their corresponding behaviors and reactions.  Then, our proactive selves digest this information and anticipate possible future actions with desired behavioral outcomes. Whew! Talk about cognitive load!

The prefrontal cortex, which means “at the front of the cortex”, is our corporate executive of the brain.  Its tasks include, but not be limited to, executive control, conflict monitoring, emotion, and working memory.   Hmm…so, maybe the cognitive load approach to interviewing is not the golden ticket, if determining veracity of intent is the interviewer’s objective.

If the above assumptions are correct, a truthful interviewee could exhibit more deceptive behavioral cues, such as pauses or exaggerated details, than a deceptive interviewee.  This might occur as a result of the multi-layer cognitive processing when creating truthful ‘memories of the future’.  Remember, false statements, especially fabricated statements, may contain some truthful content; however, the deceptive person’s goal is not to unintentionally reference past actions, which could associate them to a particular phenomenon in question.  To prevent this from occurring, deceptive persons typically shy away from referencing memories and their associated behavioral responses,  when creating false statements of intent.
