Peer Review Timelines Show Gender Gap, Large Study Reports A study of millions of life science papers revealed that manuscripts with women in key authorship roles spent longer between submission and acceptance.

Study of 8M biomed & life science articles finds those led by women spent 7 to 15 days longer in review than those led by men. Over a career, women's papers could spend 350 to 750 additional days in review. Delays could slow promotion, esp to full professor. www.the-scientist.com/women-s-rese...

Mutual Sensitivity Between Caregivers Predicts Infant Affective State During Video Chat published in Infancy

Mutual Sensitivity Between Caregivers Predicts Infant Affective State During Video Chat published in Infancy

Abstract

Infancy is an extraordinary period of human development, in which babies turn sensory and environmental information into meaning in the cradle of their caregivers’ affective and attentional cues. Babies express what they are thinking and feeling through smiles and gazes long before they develop expressive language. Most developmental research focuses on mother-infant dyads within a controlled lab environment, despite the complexity of young children’s caregiving ecosystems, which range far beyond the mother-child dyad and include caregivers at a distance via technology like video chat. This study uses a novel state space approach to examine relations between the sensitivity of two caregivers β€” what we call β€œmutual sensitivity” β€” and infants’ real-time affective and attentional states during video chat sessions.

Abstract Infancy is an extraordinary period of human development, in which babies turn sensory and environmental information into meaning in the cradle of their caregivers’ affective and attentional cues.

Most developmental research focuses on mother-infant dyads within a controlled lab environment, despite the complexity of young children’s caregiving ecosystems, which range far beyond the mother-child dyad and include caregivers at a distance via technology like video chat. This study uses a novel state space approach to examine relations between the sensitivity of two caregivers β€” what we call β€œmutual sensitivity” β€” and infants’ real-time affective and attentional states during video chat sessions.

How to read a state space (Hollenstein, 2013): This figure depicts a single infant’s affective states over three video chat sessions. Each grid square represents a unique affective state characterized by both valence (1-7, negative to positive) and arousal (1-7), high to low. For example, we can see that during the first video chat session, this infant briefly spent time in a high arousal, low valence state (distress).

Background
Caregiver sensitivity - a caregiver’s responsive, warm, temporally contingent engagement with an infant - has been robustly linked to children’s development across cognitive and affective domains. 

Prior studies have shown that global caregiver sensitivity predicts both infant affective valence and infant engagement in JVA during in-person interactions (Braungart-Rieker et al., 2001; Mason et al., 2019) and during video chat (Roche et al., 2022; Myers et al., 2024). 

In this study we used the Biringen et al., 2000 scale (1-9) and coded all behavioral variables every 30 seconds.

Socioeconomic roots of academic faculty

Tenure-track faculty are up to 25 times more likely to have a parent with a Ph.D. Moreover, this rate nearly doubles at prestigious universities and is stable across the past 50 years.

Mine (human development) were all co-authored by my advisor and others, although I did 99% of the original writing, specifically, because it did feel weird to have someone else write portions of my dissertation. I included title pages with the list of authors for all three.

Scientists make 'superfood' that could save honeybees We rely on honeybees to pollinate our crops and a new food could protect them from growing threats.

Bee news 🐝🍯πŸ§ͺ:

Scientists have developed a honeybee "superfood" that could protect the animals against the threats of climate change & habitat loss.

Bee colonies that ate the supplement during trials had up to 15 times more baby bees that grew to adulthood.
