Summary: The evolution of language has long been a topic of interest for anthropologists, psychologists, and biologists. This study focuses on wild chimpanzees and examines the relationship between social network size and different types of signals (vocal, gestural, and bimodal). The findings suggest that larger social networks are associated with a larger network of gestural signals, while response waiting is more common with gestures and elaborations are more common with vocalizations. Overall, the results suggest that gestures played a primary role in the evolution of language.

Summary: Humans are highly sensitive to patterns in the environment and use statistical learning for cognition. This study examined the neural mechanisms of statistical learning using an auditory nonlinguistic paradigm. Neural entrainment reflects implicit learning of patterns, while the emergence of explicit knowledge varies across individuals depending on factors such as attention and exposure time.

Summary: The article discusses the enduring biases toward specific locations caused by attentional habits acquired through visual statistical learning, which are believed to be independent of goal-directed and stimulus-driven attentional mechanisms. The methodological limitations in previous studies are reviewed, and recent challenging results are briefly described, leading to questioning the assumption of attentional habits being based on a special search history process that differs from the two traditionally recognized attentional mechanisms.

Summary: Successful interaction in the target language requires L2 learners to use and understand grammatically correct language that is also socioculturally appropriate. However, acquiring pragmatic competence has proven to be challenging for L2 learners due to limited exposure to authentic language use in social settings. Instruction can influence functional abilities in L2 as it helps learners produce and comprehend language in different situations.

Summary: The paper examines different definitions of creativity, focusing on standard definition and intentional novelty definition. Three studies tested the differential predictions on lay-people's judgments of creativity, supporting the importance of novelty and intentionality while questioning the role of value. The results overall supported the intentional novelty definition but did not fully support its specific predictions.

Summary: Due to the expansion of e-business, the availability of products on the internet has increased. Collaborative Filtering (CF) is the most effective recommendation method, but it faces data sparsity and cold start problems. This study proposes a new neural recommendation model based on non-iid (Non-Independent and Identically Distributed) for CF, incorporating explicit and implicit coupling interactions, and performs better than existing methods according to experiments on large real-world datasets.

Summary: This study explores how combining explicit (logos, labels, statements) and implicit packaging design cues (auditory, tactile, visual elements) can enhance sustainability salience, perception, and consumer sustainable disposal behavior. While the combination of cues may be counterproductive under certain conditions, it can positively impact sustainability awareness, perception, and behavior in other situations.

Summary: In this paper, a new approach based on hybrid explicit-implicit learning (HEI) is proposed to solve the poroelasticity problem in a fractured medium. The spatial approximation is done using the finite element method with linear basis functions, while the time approximation is achieved through an explicit-implicit scheme. The method incorporates fixed strain and fixed stress splitting schemes to simplify the calculations.

Summary: Young olive baboons exhibit near-maximal levels of grasping strength at a very early age, likely due to wider phalanges and digit joints. The mature proportions and shape of forelimb elements appear in full adulthood, while hind limb proportions and shape are observed earlier during development. These differences in limb performance and morphology reflect the different functional roles of forelimbs and hind limbs, possibly evolved under different ecological pressures.

Summary: The language-ready brain theory suggests that the infant brain is pre-wired for language acquisition, with a leftward structural brain asymmetry found in both human infants and non-linguistic primate infants. The study challenges the idea that the early PT asymmetry is a human-specific marker for language development, suggesting instead a shared evolutionary inheritance related to lateralized systems from common ancestors millions of years ago.

Summary: The corpus callosum plays a crucial role in integrating and coordinating cognitive processing in the human brain, with old age often showing atrophy of this structure. However, non-human primates like baboons do not exhibit callosal atrophy in old age, suggesting that this phenomenon may be unique to human brain aging. This observation supports the idea that corpus callosum atrophy is a distinctive characteristic of human brain aging.

Summary: Manual gestures and speech activate a shared neural network, particularly Broca's area in the left hemisphere. Investigating gestural communication in baboons, the study found that it is related to a specific lateralization feature in the frontal cortex, potentially reflecting evolutionary continuity with language-related lateralization in humans.

Summary: In this study, it was found that infants already have hand preferences for grasping in the early months of age, with a predominance of left-handedness, especially during the period they are carried by their mothers. Early postnatal handedness was positively correlated with maternal cradling lateralization, while hand preferences later in development were less dependent on maternal cradling bias, particularly in infants initially cradled on the right side. These findings suggest that the infant's hand preference and its changes across development may ultimately depend on the degree of infant dependence on the mother.

Summary: Nonhuman primates share some cognitive properties essential to language processes with humans, but it is difficult to determine whether these shared properties are a result of continuous or convergent evolution. Comparing the brain structures of humans and nonhuman primates can help determine their similarity or divergence, supporting either of the two hypotheses. Key brain regions associated with language processes show human-like structural asymmetries in nonhuman primates. The study of lateralization of the gestural communication system provides insights into the functional significance of these asymmetries.

Summary: This study examined the role of genetic factors in individual variation in superior temporal sulcus (STS) morphology in chimpanzees. The results showed significant correlations between single nucleotide polymorphisms in the KIAA0319 and AVPR1A genes and STS depth and lateralization, but no significant effects on surface area and depth measures for the central sulcus. The overall findings suggest that genetic factors contribute to a small to moderate amount of variation in STS morphology in chimpanzees.

Summary: This article examines the organization of human interactions in sequences and explores how sequence organization applies not only to human social interactions but also to non-human animals. Through studying baboons' interactions, it is found that the spatial approach of individuals influences the formatting, initiation, and response of the opening sequences. Participants interpret others' actions, responsiveness, and mutual understanding of ongoing actions based on the sequential implicativeness and expectations of the sequence organization. This provides a foundation for further exploration of the pervasiveness of the interactional engine in communication between humans and non-human primates.
