As unfashionable as it may be in many circles, I am a believer in free will. I have to be, for working as a psychologist or conducting psychological research to make any sense to me, personally. At the same time, I am keenly aware of how great an impact internal and external circumstances have on our decision-making capabilities and choices. As such, the effects of emotional states and responses on moral decisions are a fascinating topic, and that’s why I chose to present this article on a rather simple study on the effects of the anxiolytic drug lorazepam on ruthlessness in moral decisions.

Summary and Comments – Does Narrative Exposure Therapy Reduce PTSD in Survivors of Mass Violence?
Does Narrative Exposure Therapy Reduce PTSD in Survivors of Mass Violence?

As a comeback to my series of summaries of interesting scientific research articles in psychology, I’ll start with something directly relevant to my current work as a PhD Candidate researcher.
After a particularly frightening, dangerous or otherwise intensely stressful experience, stress reactions can be considered normal. However, if such symptoms persist for several months, we may speak of persistent posttraumatic stress symptoms and, in cases where they reach a certain clinically significant level, of Post-Traumatic Stress Disorder (PTSD). Typically, PTSD symptoms consist of involuntarily re-experiencing the traumatic event in some way (flashback phenomena, intrusive thoughts and memories), avoiding places, people and things that are reminders of the trauma or act as triggers for re-experiencing, and hyper-arousal (problems concentrating, sleeping, over-vigilance, feelings of danger).
The standard treatments for PTSD and related symptoms include trauma-focused and other forms of cognitive behavioral therapy. However, clinicians and researchers have found that these standard treatments often do not work so well with individuals who have repeatedly experienced many traumatic incidents, especially in contexts such as war and armed conflict. With this in mind, new forms of therapy appropriate for such sequentially traumatized individuals are needed.
One such relatively new form of therapy is Narrative Exposure Therapy (NET), developed by M. Schauer, F. Neuner and T. Elbert, drawing on emotional processing theory, trauma-focused CBT and testimonial therapy. It is a program of on average eight sessions, where emotional processing and thus healing is thought to occur through detailed narration of the traumatic events leading to habituation to their distressing effects, as well as through the reconstruction of a coherent narrative of the events and their place in the individual’s autobiographical memories. The entire life story of the patient, including her/his most negative and traumatic as well as positive experiences, is narrated and written down in detail during the therapy.
The article summarized here is a review by J. McPherson of the evidence “so far” (until 2011 or so, that is) on the effectiveness of Narrative Exposure Therapy to reduce PTSD symptoms, mainly in survivors of different forms of mass violence.
Summary and Comments – Psychedelics and Mental Health: A Population Study
Psychedelics and Mental Health: A Population Study
by Krebs, T. S., & Johansen, P-Ø. (2013)
(PLoS ONE, 8(8), e63972. DOI:10.1371/journal.pone.0063972)
Psychedelic substances, such as psilocybin-containing mushrooms, DMT-containing brews (ayahuasca), mescaline-containing cacti, ibogaine-containing roots and seeds with LSA, have been used for religious, shamanistic, divination and healing purposes by various cultures for thousands of years. Since the 1960s especially, the use of psychedelics, most commonly lysergic acid diethylamide (LSD-25), psilocybin and mescaline, has also been relatively widespread in the “Western” world for various purposes, including recreational, spiritual and religious uses.
Much research into the potential therapeutic uses of (some) psychedelics was carried out in the 1950s and 1960s, but due to political, legislative and other reasons, a long hiatus followed. In recent years, starting with DMT studies in the 1990s, and over the last 5-10 years in particular, there has been increasing renewed interest in such uses. In light of this renewed interest, research over the safety of these substances appears of great importance.
It is known that the “classic” serotonergic psychedelics, that is, LSD, psilocybin and mescaline, are physically very safe substances, non-addictive, and do not lead to violence or other major social problems in the way some psychoactive substances do. When considering the possible risks of these substances, the main concern has focused on potential mental health effects, in particular on possible links to long-term psychotic, phobic or PTSD-like symptoms. Psychedelics can indeed elicit very intense experiences in their users, often positive and even ecstatic or rapturous but sometimes negative and terrifying. In light of these extreme effects, and some (though limited) similarities in states produced by psychedelic use and those experienced during mental illness, it is not surprising that many have wondered about the connections between psychedelic use and mental health, and some case reports of long-term mental problems following psychedelic use exist.
Summary and Comments – Optimism Is Universal
Optimism Is Universal: Exploring the Presence and Benefits of Optimism in a Representative Sample of the World
by Gallagher, M. W., Lopez, S. J., & Pressman, S. D. (2013)
(Journal of Personality, 81(5). 429-440. DOI: 10.1111/jopy.12026)
Background & Research
Recent theories of and studies on optimism tend to agree that optimism is an adaptive psychological resource and provides overall benefits for individuals, rather than being a damaging delusion as was earlier thought by some philosophers and psychologists. While there are some indications that defensive pessimism may be adaptive and optimism maladaptive in some very specific circumstances, overall, numerous studies and meta-analyses have shown higher levels of optimism to be linked to improved psychological health, in particular subjective well-being, as well as subjective, and to a lesser extent objective, physical health.
However, as with so much psychological research, optimism and its effects have mainly been studied in industrialized, relatively wealthy nations. Are the results obtained in such studies then generalizable to the entire world? Is optimism a) widely present and b) adaptive in other parts of the world, where, e.g., economic outlooks may be more dire and life expectancy and other Quality of Life indicators are lower?

Summary and Comments – Is personality modulated by language?
Is personality modulated by language?
by Veltkamp, G. M., Recio, G., Jacobs, A. M., & Conrad, M. (2012)
(International Journal of Bilingualism, 17(4). 496-504. DOI: 10.1177/1367006912438894)
Background & Research
The complex relationships between language and culture, as well as thought and personality, have been the subject of great interest and research since at least the 19th century, for psychologists, linguists, philosophers and even romantic/nationalist thinkers. Linguistic relativity, for instance, was a particularly hot topic in the first half of the 20th century. As regards more recent psychological research, there are indications that different languages carry different emotional tones, in that people fluent in several languages behave and feel in different ways when speaking one language as compared to another. There is also evidence that language learning on the whole is closely tied to the internalization of cultural norms and values that appear to be inherently present in the language. It has been said that culture provides different formulaic ways for expressing thoughts and feelings, and if this is the case, language is the most likely process for this to occur through.
For multilingual individuals, researchers have suggested that by learning new languages, individuals simultaneously gain access to new cultural meaning systems, and can then switch between different culturally appropriate behaviors. If that is the case, might expressed dimensions of personality also change when using another language? Continue Reading…
