1 BIOFEEDBACK IN A CLINICAL SETTING IMPLICATION FOR POLYGRAPHY

2 Biofeedback  What is Biofeedback?  Biofeedback is the use technology to identify, modify and control one’s biology, emotions and thoughts  Types of Biofeedback  Neurofeedback (qEEG)  Symptom specific (pelvic floor dysfunction, etc.)  Autonomic Nervous System activity control  Cognitive/Emotional Regulation  Polygraph

3 Advantages of Each  Neurofeedback  Requires expensive equipment and extensive training  Target specific neurological deficits  Identifies areas of deficit in Brodmann areas  Map of areas of low and high activity determine treatment  Under activated areas can be stimulated for additional activity  Areas of over activity are balances by activation of inhibitory systems

4 Brodmann Areas

5 EEG Neurofeedback

6 Types of Biofeedback  Symptom Specific Treatment  Requires expensive equipment and extensive training  Typically carried out in a medical setting  Target symptoms that are treatable without medication  Teach clients to self treat outside the practitioners office  Develops independence from regular medical intervention

7 Types of Biofeedback  Autonomic Nervous System Activity  Uses a variety of equipment (ranging in price)  Treats systemic medical issues  Target symptoms that are treatable without medication  Teach clients to self treat outside the practitioners office  Develops independence from regular medical intervention

8 Pelvic Floor Feedback

9 Types of Biofeedback  Cognitive/Emotional Regulation  Uses equipment that of varying price (typically inexpensive)  Can be effectively used by practitioners with very little training  Can be used by clients remotely (home, work, travel)  Effectively regulates the body, causing changes in the internal state

10 Types of Biofeedback  Polygraph  Uses expensive equipment  Requires extensive training  Only clinical use is to break down denial  Should NOT include any type of emotional management by the client  Passive response

11 Polygraph

12 UNDERSTANDING THE BODY AND BRAIN

13 Understanding the Body and Brain

14 A brain in your hand…  Or just try the clenched fist method  Wrist and arm is spinal column,  thumb becomes limbic system,  and fingers and back of hand become cerebrum. The entire system is held together tightly. The cerebrum, the outer part, is divided up into lobes.

15 Frontal Lobes Planning, thinking Rational and executive control center Monitor higher order thinking Direct problem solving “Regulates the excesses of the emotional system” “Self-Will” area – our personality – trauma here can cause permanent and dramatic changes in personality. Time/sequence Spirituality Courtesy of Drew Caesar www.about-healing.com

16 Limbic - so called “old mammalian brain”– emotions, desires, fight, flight, or freeze Includes many parts of the brain – thalamus, hypothalamus, corpus callosum, amygdala, hippocampus, pituitary gland, olfactory nerves. Courtesy of Drew Caesar www.about-healing.com

17 Hippocampus Hippocampus (Greek for “seahorse” because of shape)  Plays significant role in consolidating learning converts information from working memory to long term storage which may take days or months (think tx. concepts)  checks information from working memory and compares to stored experiences – essential for creating meaning  Damage to it means that memory doesn’t go into long term storage.  Some evidence says that it plays a role in remembering facts, objects, and places but not much of a role in recall of long term personal memories (Lieberman, 2005) Courtesy of Drew Caesar www.about-healing.com

18 Amygdala Amygdala (Greek for “Almond”) Found at the end of the hippocampus  Involved in emotions – especially fear and threat and assessment of threat  Connected with organisms survival behaviors, flight, fight, freeze, mate, eat  Some evidence to indicate it attaches emotions to memories tagged for long term storage.

19 The Lizard Brain Brain Stem – So called, reptilian brain, resembles the entire brain of reptile Of the twelve nerves that go to the brain from the body, eleven end in the brain stem. Consists in part of the Medulla oblongata – heart rate, breathing – body temperature, digestion monitored and controlled.  Houses the Reticular Activating System (RAS) responsible for brains alertness Courtesy of Drew Caesar www.about-healing.com

21 Selecting Appropriate Clients  Disorders  PTSD  Anxiety General Panic Attacks  Dissociative Disorders  Depressive Disorder NOS  Traumatized Clients  Highly aroused  Depersonalized  Reactive  Substance Abuse  Sexual Arousal Disorder  Impulse Control  Antisocial / CD

22 Inappropriate Clients Don’t Train Biofeedback  Previous Use of Countermeasures  Previous deceptive with denial Don’t Polygraph  Uncontrolled Anxiety  Dissociative  Reactive/Victims  Clients some drugs/medication

23 The Technology  emWave  Iom (Wild Divine)

24 Reading  HRV  Looks at the rhythm of your heart  Emotions change the variability of signals  Goal is to gain Coherence  GSR  An indication of mental activity  More thought = higher perspiration  Less thought = lower perspiration  Perspiration = electrical conductance

25 emWave Desktop

26 Fear Reactions  Fear triggers initiate a reaction in the autonomic nervous system including:  Hypertension  Perspiration  Involuntary muscle movement  Increase in GSR  Increase in rapid breathing

27 Techniques  Mindfulness  Decrease galvanic skin response  Decrease stress response  Quick Coherence  Change in heart rate variability  Decreased cortisol production  Increases in attention, clarity

28 Classic Systematic Desensitization

29 Pendulation  Emersion  Use basic visualization of disturbing content  Illicit negative emotions  Notice sensory stimulation  Stabilization  Obtain stable physiological response  Useful with emWave and Wild Divine

30 No Nos  Biofeedback should not be used as a mini- polygraph  Don’t give specific questions  Do deal with the big concepts  “Let’s talk about the feelings that come up with family”

31 POLYGRAPH AND COUNTERMEASURES

32 Demonstration

33 Containment Model Sex Offense Specific Treatment Polygraph Examiner Community Members Sex Offense Specific Treatment Polygraph Examiner Community Members Criminal Justice System

34 Types of Clinical Polygraphs  Specific Issue  Addresses offender denial  Sexual History Disclosure  Treatment Planning  Risk Prediction  Maintenance / Monitoring

35 How Does the Polygraph Work?  It activates the “Flight or Fight” response in humans and measures.  1. Heart Rate  2. Certain Respiration Patterns  3. Galvanic Skin Response (the skin’s resistance to electricity)  4.Blood Pressure These measures are associated with deception and are not themselves measures of lying. I can’t control my autonomic nervous system!!

36  1. Pre-Test  Sign release and consent forms  Review medical conditions  Explain purpose of exam  Review equipment  Review terminology  Develop final questions  Calibrate instrument  2. In-Test  No trick questions  2-4 relevant questions tucked inside 10-20 comparison questions  Relevant questions must be specific  Run 3 sets of charts  Score and interpret chart markings (pen tracings)  3. Post Test  Conducting an indepth interview with examinee, giving him/her an opportunity to explain deceptive findings What happens during an exam?

37 Use of Polygraph in Offense Specific Treatment Types of Polygraph  preconviction specific issue  postconviction specific issue sexual history maintenance Benefits of Polygraph  significantly increases disclosure  resolve discrepancy between victim’s and offender’s statements  ascertain limits of abusive behavior  deter further acting out  more accurate than clinical judgement

38 You Play A Role In Polygraph Exam Accuracy  “The Offender must believe in the ability of the lie-catcher.” Ekman, 1995  Examiners are trained to induce detection apprehension.  You, too, can induce detection!  Make consequences for not passing clear.  Focus on telling the truth.  Make it very clear that YOU believe in the exam and will act on its results.

39 Can You Fool the Polygraph? Countermeasures fall into several categories: 1. Physical- coughing, moving, biting tongue 2. Mental- relaxation techniques 3. Chemical- drugs, deodorant on palms 4. Behavioral- directed toward examiner: stories of woe, demanding specific wording Examiners are trained to detect and deflect countermeasures.

40 Summary: Polygraph 101 Polygraph Technology greatly enhances our ability to determine truthfulness and deception, but the real focus is developing truthfulness and honesty as life habits. “Passing the polygraph” is a distraction from the real issue: Success is a lifelong commitment to living without secrets and lies. English, Jones, in process, 2001

42 No Use of Biofeedback

43 Polygraph and emWave  Decreases total amplitude of response of all the physiological reactions  Differences between reactions on the control and the relevant questions were still seen  Polygraph on a client with emWave training is valid

44 Polygraph and Wild Divine  Slowed breathing (3-4) breaths per 25 seconds is a sign of breathing control  Uncontrolled breathing should be 5-6 breaths per 25 seconds  Blood pressure changes without movement may be a sign of countermeasures.

45 Using Biofeedback (emWave)

46 What is this and why does it matter?
