Usually I hate reading through proofs but pretty proud of this one.

Lucky i have such legends for coauthors.

Interested in targeting habit or hedonic motivation to make health behavior change last? Then keep an eye out for this one to be published soon. Don't tell me if I missed type-os!

This article considers an important but relatively neglected contributor to the failure to replicate results from experiments in motivation and emotionโ€”messy methods. By methods, we mean the procedures used to collect data and test hypotheses, which concern issues such as experimental design and validity. We offer a set of recommendations for establishing strong and valid experimental methods for both original research and replications. We first consider the lab room setup, starting with the physical environment participants see on the way to the lab, as well as the physical environment of the lab room itself. Then, we explain the importance of a cover story and the psychological state of the participants prior to the beginning of the experiment. In addition, we consider experimentersโ€™ and confederatesโ€™ behavior and appearance, the need for experimenters to be blind to conditions, and the difficulties of having multiple experimenters conduct one experiment. Next, we discuss the construction of strong independent variables, interactions between independent variables, manipulation checks, how the psychological meaning of an independent variable can change over time and place, demand characteristics, and confounds. When considering dependent variables, we explain how to construct sensitive ones and the importance of pretesting. Then, we apply these recommendations to replications and finish by considering some data management and statistical issues. We hope this article will be a useful resource for both students and experienced scientists.

I created this reading list on theory in psychology a while back, so it probably needs an update! Would love any recommendations for papers to include โ€“ maybe I can turn this into a syllabus of sorts.

Defining and characterizing team resilience in elite sport The objectives of this study were to develop a definition of team resilience and to identify the resilient characteristics of elite sport teams.Focus โ€ฆ

โ€œTeam resilience is a dynamic process that protects us from shared stressors and helps us adapt.โ€

This idea from Morgan, Fletcher, & Sarkar hits home right now. Science isnโ€™t a solo gameโ€”itโ€™s our ability to stick together and adapt that keeps us going.

Summary of the study. A: The schematic shows the experimental procedure, illustrating five weekly lab visits followed by 2 MR visits labeled from S1 to S7. After the first session (S1), participants undergo four weeks of continuous glucose monitoring (CGM) combined with ecological momentary assessment (EMA). B: The CGM system uses a small flex sensor placed at the posterior upper arm that is inserted in the subcutaneous fatty tissue. The glucose sensor, positioned beneath the skin surface layers (epidermis and dermis), measures glucose levels in the interstitial fluid within the subcutaneous adipose tissue. The data is wirelessly sent via near field communication (NFC) to the FreeStyle Libre 3 app on the participantโ€™s cell phone. The accuracy of the sensor concerning capillary glucose has been validated (Alva et al., 2022). C: Participants rate their metabolic and mood states twice daily using a visual analog scale (VAS), ranging from 0 (not at all) to 100 (very).

Do you get in a bad mood if you are hungry? Over 4 weeks with EMA+CGM, we tested if mood shifts are subconsciously driven by glucose levels or ratings of metabolic state #neuroskyence ๐Ÿฉบ
