Intuïtie maakt meer kapot dan je lief is (by Harald Merckelbach)
We zijn moraalridders. We nemen elkaar de godganse dag de maat. We hebben minder dan een seconde nodig om de een aardig en de ander een schurk te vinden. En daar maken we onze medemens vervolgens ruimhartig deelgenoot van, bij de koffiemachine of op Twitter. Dat schept een band. Maar met die intuïties van ons slaan we voortdurend de plank mis. Vooral in de rechtszaal kan dat dan verkeerd uitpakken. Intuïtie maakt meer kapot dan je lief is laat zien wat er dan gebeurt. Het gaat over boeven die er reuze sympathiek uitzien en daarom de dans ontspringen. Over onschuldige burgers die we een misdaad in de schoenen proberen te schuiven. En over verstandige politiemensen, officieren van justitie, rechters en getuigen-deskundigen die toch miskleunen. Wat moeten we dan wel doen? Het korte antwoord: onze intuïtie hevig wantrouwen en zo lang mogelijk buiten de deur houden. Het langere antwoord, geïllustreerd aan de hand van luchtige, hilarische, maar ook tragische voorbeelden, is dit boek. Harald Merckelbach (1959) is hoogleraar rechtspsychologie aan de Universiteit Maastricht. Hij schrijft wetenschapscolumns voor NRC Handelsblad. Hij trad vaak op als getuige-deskundige in strafzaken.

Routes van het Recht - Over de rechtspsychologie (by Peter van Koppen, Jan de Keijser, Robert Horselenberg, Marko Jelicic)
De rechtspsychologie gaat over het gedrag van mensen in het recht. Over getuigen en hoe zij worden ondervraagd. Over rechters en hoe zij beslissen. Over politiemensen en hoe zij misdrijven proberen op te lossen. Over verdachten en over hoe en waarom zij misdrijven plegen. In Routes van het Recht wordt die psychologie van het recht, en nog veel meer, uiteengezet aan de hand van de kennis die in het vakgebied in de afgelopen honderd jaar is verzameld.
Zonder onnodig juridisch en psychologisch jargon worden vragen over herkenningen, leugendetectie, forensisch-psychologische tests, rechterlijke dwalingen en verhoren van kinderen, volwassenen en verdachten beantwoord. Het is een bijzonder naslagwerk en uitstekend geschikt als cursusmateriaal.

Finding the Truth in the Courtroom (Henry Otgaar & Mark L. Howe)
Finding the Truth in the Courtroom combines the science behind deception and memory and their relation in court. Testimonies are oftentimes the most important piece of evidence in legal cases. Hence, this book shows how such testimonies can be riddled with deception and/or memory errors, how to detect them, and what you can against them.

Forensic Psychological Assessment in Practice (by Corine de Ruiter & Nancy Kaser Boyd)
Forensic Psychological Assessment in Practice: Case Studies presents a set of forensic criminal cases as examples of a scientist-practitioner model for forensic psychological assessment. The cases involve a number of forensic issues, such as criminal responsibility, violence risk assessment, treatment planning, and referral to long term forensic care. Likewise, different types of offenses are covered, for example, sexual offending, arson, homicide, robbery and domestic violence. The authors address a variety of mental disorders including psychosis, posttraumatic stress disorder, psychopathy and other personality disorders. The book will be useful for novice and experienced forensic psychologists and psychiatrists who are looking for case studies that integrate the most recent empirical evidence with psychological test findings.

Memory Detection: Theory and application of the concealed information test (by Bruno Verschuere, Gershon Ben-Shakhar & Ewout Meijer)
Traditional techniques for detecting deception, such as the lie-detector test (or polygraph), are based upon the idea that lying is associated with stress. However, it is possible that people telling the truth will experience stress, whereas not all liars will. Because of this, the validity of such methods is questionable. As an alternative, a knowledge-based approach known as the Concealed Information Test has been developed which investigates whether the examinee recognizes secret information - for example a crime suspect recognizing critical crime details that only the culprit could know. The Concealed Information Test has been supported by decades of research, and is used widely in Japan. This is the first book to focus on this exciting approach and will be of interest to law enforcement agencies and academics and professionals in psychology, criminology, policing and law.
