Investigations and courtroom :
The Sunday Times (25 Nov) reports on a new facial morphing technique called EvoFIT “that transforms the Photofit faces of criminal suspects into animated caricatures up to seven times more likely to be recognised than standard likenesses”. The system was developed by UK psychologists, one of whom commented that using the new system leads to “…a massive jump in the level of recognition [which] is really reliable”. Lots more information including plenty of downloadable papers on the EvoFIT webpages .
The Eyewitness Identification Reform blog highlights scholarly commentary on the effectiveness of cross-examination for getting at the truth of eyewitness evidence.
Following a detailed and extensively researched analysis, Prof. Epstein [the author of the commentary] concludes that the highly revered truth-seeking tool of cross-examination, while perhaps effective at rooting out liars, is utterly ineffective at uncovering the truth when faced with a witness who is confident, but honestly mistaken about what he or she remembers – which accounts for the majority of cases in which mistaken identification has led to wrongful conviction.
Mo over at Neurophilosophy (a great blog that doesn’t often post on forensic issues) discusses research on creating false memories by doctoring photographs. Participants who saw altered images had different memories of the events in the photographs:
For example, those participants shown the doctored photograph of [a] protest in Rome…in which figures placed in the foreground give the impression of violence, rated the event as being significantly more violent and negative than it actually was. In their comments, they also provided false details, such as conflicts, damages, injuries and casualties that did not appear in the photos and were not documented at the event.
The whole issue of Applied Cognitive Psychology is about ‘cognition and the media’ and includes other papers on the fallability of memory, which will be of use to anyone interested in eyewitness memory.
Anne Reed at the fabulous Deliberations blog reports on research into the Grim Power of Grim Evidence. Apparently “jurors presented with gruesome evidence, such as descriptions or images of torture and mutilation, are up to five times more likely to convict a defendant than jurors not privy to such evidence.”
The ever-interesting Karen Franklin comments on juvenile detention, and starts by posing some simple questions with disturbing answers. Did you know, for instance, that only two nations sentence children to life in prison? According to Karen, they?are Israel, with 7?child?lifers, and the USA, with an astonishing 2,387 child lifers.
Michael Connolly at Corrections Sentencing offers a detailed discussion of an article which “calls for broad application of empirical psychology to the study of the motive behind punishments”. The article is in press and due to appear in 2008.

The criminal psychopath is the topic of a post at Top Two Inches, and over at the Deception Blog, a comment on research on whether psychopathic liars give themselves away through their verbal behaviour.
Crimson Shadows posts (with permission) the full text of ex-FBI profiler John Douglas’s response to Malcolm Gladwell’s article on profiling that appeared in the New Yorker last month. Douglas argues that Gladwell’s article misrepresents the science and practice of profiling.
Terrific analysis of?an fMRI study linking paedophilia to differences in the brain?over?at?the?Brain?Ethics?blog, ?critiquing both the method and the interpretation?of?the?results?of?this?study.??In?sum?“at the least, just because the brain shows a difference, one cannot conclude anything beyond this about causation.”
The BPS Research Digest has also included a couple of forensically relevant posts recently: detecting feigned mental retardation and inter-ethnic violence.
As well as the post on juvenile detention mentioned above, Karen Franklin’s posted a lot of other good stuff recently too, including pointing us towards a Canadian news article on false confessions, commenting on how the UK is considering stricter controls on the use of expert scientific evidence, and a great piece on tracking serial killers in South Africa.
Romeo Vitelli’s Providentia blog reports on an intervention program for young victims of violence, child abuse and brain development, and an usual case of car fetishism.
