Revisiting the Object‐Processing Paradigm in the Study of Gaze Cues
Infants are highly sensitive to social stimuli from early on in ontogeny. Social cues, including others' gaze, not only capture and guide infants' attention, but also modulate the efficiency in which the infant (brain) encodes and recognizes information. Over the last two decades, the novelty preference based object‐processing paradigm has been instrumental in investigating this phenomenon experimentally. This paper offers a comprehensive review …
Morphological and Morphometric Analysis of Animal Hair From 18th Century Burial Sites in Mazamet (Southwest France)
Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or badger hair. In contrast, SP04 samples showed a fragmented medulla, a slightly higher medullary index (0.26 ± …
Theta power relates to infant object encoding in naturalistic mother-infant interactions
This study investigates infants' neural and behavioral responses to maternal ostensive signals during naturalistic mother-infant interactions and their effects on object encoding. Mothers familiarized their 9- to 10-month-olds (N = 35, 17 females, mainly White, data collection: 2018–2019) with objects with or without mutual gaze, infant-directed speech, and calling the infant's name. Ostensive signals focused infants' attention on objects and the…
Influence of altered freshwater discharge on the seasonality of nutrient distributions near La Grande River, northeastern James Bay, Québec
In subarctic marine environments, nutrient stocks are replenished through physical and biogeochemical processes in winter, largely setting an upper limit on new primary production for the next growing season. In spring, marine nutrient stocks are modified by freshwater-associated additions, especially in coastal areas. Hydroelectric development of the La Grande River (LGR) in northern Québec has shifted the timing of peak freshwater discharge fro…
Direct and Observed Joint Attention Modulate 9-Month-Old Infants’ Object Encoding
Sharing joint visual attention to an object with another person biases infants to encode qualitatively different object properties compared to a parallel attention situation lacking interpersonal sharedness. This study investigated whether merely observing joint attention amongst others shows the same effect. In Experiment 1 (first-party replication experiment), N = 36 9-month-old German infants were presented with a violation-of-expectation task…
L’école à la maison en situation de confinement total ou partiel
Durant le premier confinement lié à la pandémie de Covid-19 en mars 2020, l’école à la maison est devenue la norme. Outre le télétravail, les familles ont été confrontées à la scolarisation à distance de leurs enfants, imposant une cohabitation d’espace-temps et de pratiques numériques familiales et scolaires. Quelles transformations de l’espace-temps familial sont-elles induites par la réalisation à la maison de l’ensemble des activités scolaire…
Net heterotrophy in High Arctic first-year and multi-year spring sea ice
The net productivity of sea ice is determined by the physical and geochemical characteristics of the ice–ocean system and the activity of organisms inhabiting the ice. Differences in habitat suitability between first-year and multi-year sea ice can affect the ice algal community composition and acclimation state, introducing considerable variability to primary production within each ice type. In this study, we characterized the biogeochemical var…
When it pays off to take a look
Social cues and instrumental learning are two aspects potentially fostering early gaze following. We systematically investigated the influence of social features (schematic eyes vs. reverse‐contrast eyes) and gaze‐contingent reinforcement (elicited vs. not elicited) on 4‐month‐olds’ learning to attend to gaze‐cued objects. In 4 experiments, we tested infants’ ( N = 74) gaze following of a turning block with schematic or reverse‐contrast eyes. In …

Effects of Reinforcement Learning on Gaze Following of Gaze and Head Direction in Early Infancy
The current four experiments investigated gaze following behavior in response to gaze and head turns in 4-month-olds and how reinforcement learning influences this behavior (N = 99). Using interactive eye tracking, infants’ gaze elicited an animation whenever infants followed a person’s head or gaze orientation (Experiment 1.1, 2.1 and 2.2) or looked at the opposite side (Experiment 1.2). Infants spontaneously followed the direction of a turning …
Infants’ Preference for Social Interactions Increases from 7 to 13 Months of Age
This study examined 7-to-13.5-month-old middle-class Western infants’ visual orienting to third-party interactions in parallel with their social attention behavior during own social interactions (Leipzig, Germany). In Experiment 1, 9.5- to-11-month-olds (n = 20) looked longer than 7- to-8.5-month-olds (n = 20) at videos showing two adults interacting with one another when simultaneously presented with a scene showing two adults acting individuall…
Social interaction targets enhance 13‐month‐old infants' associative learning
Infants are attentive to third‐party interactions, but the underlying mechanisms of this preference remain understudied. This study examined whether 13‐month‐old infants ( N = 32) selectively learn cue–target associations guiding them to videos depicting a social interaction scene. In a visual learning task, two geometrical shapes were repeatedly paired with two kinds of target videos: two adults interacting with one another (social interaction) …
Observing others’ joint attention increases 9-month-old infants’ object encoding
In direct interactions with others, 9-month-old infants' learning about objects is facilitated when the interaction partner addresses the infant through eye contact before looking toward an object. In this study we investigated whether similar factors promote infants' observational learning from third-party interactions. In Experiment 1, 9-month-old typically developing infants from mixed socioeconomic backgrounds from urban Germany (N = 32, 13 f…
Fatty acids and stable isotope signatures of first-year and multiyear sea ice in the Canadian High Arctic
Ice algae are critical components to the lipid-driven Arctic marine food web, particularly early in the spring. As little is known about these communities in multiyear ice (MYI), we aimed to provide a baseline of fatty acid (FA) and stable isotope signatures of sea-ice communities in MYI from the Lincoln Sea and compare these biomarkers to first-year ice (FYI). Significant differences in the relative proportions of approximately 25% of the identi…
Culturable diversity of Arctic phytoplankton during pack ice melting
Massive phytoplankton blooms develop at the Arctic ice edge, sometimes extending far under the pack ice. An extensive culturing effort was conducted before and during a phytoplankton bloom in Baffin Bay between April and July 2016. Different isolation strategies were applied, including flow cytometry cell sorting, manual single cell pipetting, and serial dilution. Although all three techniques yielded the most common organisms, each technique ret…
Quantifying Sources of Variability in Infancy Research Using the Infant-Directed-Speech Preference
Psychological scientists have become increasingly concerned with issues related to methodology and replicability, and infancy researchers in particular face specific challenges related to replicability: For example, high-powered studies are difficult to conduct, testing conditions vary across labs, and different labs have access to different infant populations. Addressing these concerns, we report on a large-scale, multisite study aimed at (a) as…
Polysaccharide hydrolysis in the presence of oil and dispersants
Oceanic oil-degrading bacteria produce copious amounts of exopolymeric substances (EPS) that facilitate their access to oil. The fate of EPS in the water column is in part determined by activities of heterotrophic microbes capable of utilizing EPS compounds as carbon and energy sources. To evaluate the potential of natural microbial communities to degrade EPS produced during oil degradation, we measured potential hydrolysis rates of six structura…
Late spring bloom development of pelagic diatoms in Baffin Bay
The Arctic Ocean is particularly affected by climate change, with changes in sea ice cover expected to impact phytoplankton primary production. During the Green Edge expedition, the development of the late spring–early summer diatom bloom was studied in relation with the sea ice retreat by multiple transects across the marginal ice zone. Biogenic silica concentrations and uptake rates were measured. In addition, diatom assemblage structures and t…
Essential gaps and uncertainties in the understanding of the roles and functions of Arctic sea ice
While Arctic sea ice is changing, new observation methods are developed and process understanding improves, whereas gaps in observations and understanding evolve. Some previous gaps are filled, while others remain, or come up new. Knowing about the status of observation and knowledge gaps is important for interpreting observation and research results, interpretation and use of key climate indicators, and for research and observation planning. Thi…
Event-related potentials discriminate familiar and unusual goal outcomes in 5-month-olds and adults
Previous event-related potential (ERP) work has indicated that the neural processing of action sequences develops with age. Although adults and 9-month-olds use a semantic processing system, perceiving actions activates attentional processes in 7-month-olds. However, presenting a sequence of action context, action execution and action conclusion could challenge infants' developing working memory capacities. A shortened stimulus presentation of a …
Methods for biogeochemical studies of sea ice
Over the past two decades, with recognition that the ocean’s sea-ice cover is neither insensitive to climate change nor a barrier to light and matter, research in sea-ice biogeochemistry has accelerated significantly, bringing together a multi-disciplinary community from a variety of fields. This disciplinary diversity has contributed a wide range of methodological techniques and approaches to sea-ice studies, complicating comparisons of the resu…
Temporal and spatial variability in sea-ice carbon
To enhance the accuracy of carbon cycling models as applied to sea ice in the changing Arctic, we analyzed a large data set of particulate organic carbon (POC) and nitrogen (PON) measurements in first-year bottom sea ice (n = 257) from two Arctic shelves, the Canadian Arctic Archipelago and Beaufort Sea shelf, including dark winter and spring seasonal measurements. Wide ranges of sea-ice POC:PON ratios were observed during both the dark winter (1…
