A single Spanish version of maternal and paternal postnatal attachment scales: validation and conceptual analysis

Editor rating: 8 / 10

Antonio Palazón-Bru –– A paper to determine that the Spanish version of this test is useful for clinical practice.
Assessing distinct patterns of cognitive aging using tissue-specific brain age prediction based on diffusion tensor imaging and brain morphometry

Section Editor rating: 8 / 10

Stephen Macknik –– The editor and reviewers are enthusiastic.
Not all brawn, but some brain. Strength gains after training alters kinematic motor abundance in hopping

Editor rating: 8 / 10

Mario Negrello –– This article advances of our understanding of motor synergies with a well quantified case of motor abundance, clear methods and meaningful results. It uses uncontrolled manifold analysis (UCM) to model and quantify motor abundance, and provides support for the interesting idea that neural systems help shape motor abundance.
Serotonin 5-HT1A receptor binding and self-transcendence in healthy control subjects—a replication study using Bayesian hypothesis testing

Editor rating: 8 / 10

Kevin Black –– The authors do real science here, following up on an initial finding from a pilot study and reporting the outcome appropriately. That may sound obvious, but in the real world of research these days it is a delightful breath of fresh hair.
Clustering of fMRI data: the elusive optimal number of clusters

Editor rating: 9 / 10

Jafri Abdullah –– the number of clusters have always been debatable,
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?

Section Editor rating: 8 / 10

Stephen Macknik –– The reviewers and editors all agree that this is high impact.
Post-traumatic stress symptoms are associated with better performance on a delayed match-to-position task

Section Editor rating: 8 / 10

Stephen Macknik –– This study reveals a potential novel mechanistic pathway in ptsd, a major health concern
Effects of mental health interventions for students in higher education are sustainable over time: a systematic review and meta-analysis of randomized controlled trials

Section Editor rating: 8 / 10

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