“Dominant men are faster in decision-making situations and exhibit a distinct neural signal for promptness; (2018)

Summary

This study was performed by two of Persometrics's very own (hosted and funded by the Brain Mind Institute at the EPFL) and is therefore listed here on top out of shear pride. Feel free to contact us for a copy. We showed that dominant males (as measured through questionnaires tapping the wish and propensity to seek to dominate others) are faster than their less dominant counter-parts. The speed advantage was shown in both behavioural tasks (of which there were a variety) and in physiological measurements (EEG). It is believed that this fast reaction time creates an advantage which is what leads men to be treated differently by others, in turn creating the dominant personality trait. We say dominant "men" because we did not study females, not because it does not apply to females. Questionnaire will be available on persometrics.com soon!

Summary

Georg Alpers and colleagues who study Anxiety disorders and Behavior therapy at University of Salzburg looked into cortisol response in people who have a phobia against driving. As was expected, cortisol response to driving exposure followed both subjective ratings and could be predicted by prior knowledge regarding the phobia. This research has been used for our stress reactivity test.

A meta-analysis by Emma Adam and colleagues at Northwestern University (Illinois, USA) on the link between the daily pattern of cortisol secretion (circadian or diurnal cortisol) and chronic psychosocial stress, physical outcomes such as inflammation. This research is important for our stress report products.

Summary

The study conducted by Eran Segal and colleagues at the Weizman institute suggests that we are asking the wrong question when searching for the right diet and should instead be looking for individualised diets. The researchers used blood sugar spikes as a biomarker for food reactivity and followed some 800 participants longitudinally showing that people differ in their response to food stuffs. An experimental follow-up (diet-intervention) confirmed: the one and same food could have opposite spike patterns for two people. Persometrics finds this a compelling first step to individualised nutrition, and especially promising that the authors incorporate the microbiome in their research, which has been used for our stress reports and has also figured on our social media outlets.

Summary

Boesch and colleagues at University of Zurich, ETH Zurich and University of Western Ontario, show a link between cortisol in hair and stress, humidity, temperature as well as socioeconomic factors and physiological data such as sweating. Stress through military trainig could not be detected in cortisol concentrations in hair, whereas meteorological data could predict some variance, showing that this technique is experimental and requires stringent control of external variables. Inter-subject factors predicted concentrations as well. Persometrics’s take is that this technique is best used to compare one’s own state across different times.

This study by Broadley & Korszun and colleagues was conducted on 36 participants between hospitals at Torquay, London, Birmingham and Cardiff and shows that blocking cortisol production with metyrapone stopped baroreflex sensitivity impairment, thus suggesting that the link between stress and coronary heart disease and sudden cardiac death is mediated by cortisol, the stress hormone.<h4>Added to Persometrics’s library: June 2017.

Study by Candy, Chalder and colleagues from Department of Immunology the School of Medicine and Institute of Psychiatry in London, looking at cortisol as a risk factor for Chronic fatigue. Results were inconclusive as regards to biological mechanisms responsible for the link between infectious mononucleosis and chronic fatigue from this study: rather, the factors that best predicted the illness changed over time.

Summary

This meta-analysis by Chida and Steptoe looks at the link between the Cortisol Awakening Response (CAR) and a range of psychosocial difficulties, including Burnout and fatigue; Depression and anxiety; HPA axis; Job stress; Positive well-being; and Posttraumatic stress disorder (PTSD). They show how predictions of Cortisol Awakening Response (CAR) has been inconclusive in a range of studies. However, their findings point to an important distinction of looking at the different ways of analysing CAR (respect to baseline or to ground, CARi or CARtot). Persometrics always combines Psychometric data when making sense of hormone data.

Danhof-Ponta,⁎, Tineke van Veenb, Frans G. Zitman from Leiden University medical Center and Leiden University (NL). We value this research which shows that basal cortisol cannot predict burnout on large scale on its own, nor can the CAR predict burnout after the fact (which is what is shown in correlational studies). We hold the importance of psychometric data in conjunction with hormonal, and point to the cortisol index which is important immediately before, not after, a burnout.

Summary

This meta-analysis was used as background reading for stress profiling. It includes studies on major depressive disorder anxiety PTSD, and other psychiatric disorders including schizophrenia. Stress manipulation included use of the Trier Social Stress Test (TSST) or other psychosocial stress tasks. Sex differences were found in stress reactivity, and this depended on the psychiatric disorder.
