Does Twitter language reliably predict heart disease? A commentary on Eichstaedt et al. (2015a)

Editor rating: 8 / 10

Tjeerd Boonstra –– The article re-examines the results of an influential paper and challenges the idea that social media data analysed on a county-level may provide a reliable predictor of health outcomes. The authors raise several questions on the reliability of data and study design that need to be addressed for this field going forward.
Explanation of observational data engenders a causal belief about smoking and cancer

Editor rating: 8 / 10

Andrew Gray –– Causality is one of the most important principles in research, but also one that is often misunderstood in particular contexts. This article provides an important warning that in our attempts as authors to provide candidate reasons for our observational research findings, we may be inadvertently encouraging our readers to believe that there is a true causal link (rather than simply an association) at play. If these results are replicated in other domains and settings, this will provide a foundation and strong motivation for testing approaches to reduce the risk that evidence from observational studies is over-interpreted, both by other researchers and by the public.
Why is nonword reading so variable in adult skilled readers?

Stephen Macknik –– The reviewers and editors all agree that this is high impact.

Section Editor rating: 8 / 10

Stephen Macknik –– Looks really relevant to all fields of science and STEM.

Stephen Macknik –– I believe this paper will be widely read
Influence of allelic variations in relation to norepinephrine and mineralocorticoid receptors on psychopathic traits: a pilot study

Editor rating: 9 / 10

Jafri Abdullah –– Receptor studies are the blue ocean for future drugs that will cure brain,mind and neurological diseases
Attentional biases toward body images in males at high risk of muscle dysmorphia

Editor rating: 8 / 10

Ada Zohar –– This is a relatively new and interesting approach to measure the automatic biases which might underlie the susceptibility to eating disorders and body dysmorphia. There is an emergent field of attention bias modification which is a new approach to treating anxiety disorders and PTSD which is showing great promise for these disorders. Since ED and BD are notoriously hard to treat this emergent research on attention bias and attention bias modification which is bringing together clinical, cognitive, and neuro psychology, is exciting, and I am glad that PeerJ is publishing this paper.
Assessment of brain functional connectome alternations and correlation with depression and anxiety in major depressive disorders

Editor rating: 9 / 10

Jafri Abdullah –– Standardization of studies in depression who are treated and those who are not are quite important.Papers from a Chinese cohort with depression is also interesting to note based on cultural bias
Adult zebra finches rehearse highly variable song patterns during sleep

Editor rating: 9 / 10

Lesley Rogers –– Rehearsal during sleep and memory consolidation is a big issue. This is an excellent paper.
