Human memory, like other biological systems, has been subject to natural selection over the course of evolution. However, cognitive systems do not fossilize, which means that current researchers must infer evolutionary influences on human memory from current human behavior rather than from fossils or artifacts. Examining the potential for cognition as adaptation has often been ignored by cognitive psychology. Recently, a number of researchers have identified variables that affect human memory that may reflect these ancestral influences. These include survival processing, future-oriented processing, spatial memory, cheater detection, face memory and a variety of social influences on memory. The current volume grew out of discussion at the symposium on survival processing at the SARMAC conference in June 2011, in New York City. The goal of this volume will be to present the best theoretical and empirical work on the adaptive nature of memory. It features the most current work of a number of cognitive psychologists, developmental psychologists, comparative psychologists and cognitive neuroscientists, who have focused on this issue. This is important because much this work is necessarily interdisciplinary and is therefore spread out across a range of journals and conferences.

In many criminal trials, forensic technical evidence is lacking and triers of fact must rely on the reliability of eyewitness statements, identifications, and testimony; however, such reports can be riddled with deceptive statements or erroneous recollections. Based on such considerations, the question arises as to how one should weigh such eyewitness accounts given the theoretical and empirical knowledge in this field. Finding the Truth in the Courtroom focuses on how legal professionals, legal/forensic psychologists, and memory researchers can decide when statements or identifications are based on truthful or fabricated experiences and whether one can distinguish between lies, deception, and false memories. The contributors, key experts in the field, assemble recent experimental work and case studies in which deception or false memory plays a dominant role. Topics discussed relate to the susceptibility to suggestive pressure (e.g., "Under which circumstances are children or adults the most vulnerable to suggestion?"), the fabrication of symptoms (e.g., "How to detect whether PTSD symptoms are malingered?"), and the detection of deceit (e.g., "Which paradigms are promising in deception detection?"), among others. By using this approach, this volume unites diverse streams of research (i.e., deception, malingering, false memory) that are involved in the reliability of eyewitness statements.
