RESUMO
'Antibiotics under our feet' is a Scottish citizen science project that aimed to raise science capital in primary school learners and their teachers through measurement of microbial diversity in urban soil samples in the search for novel antimicrobial compounds. Resistance to antibiotics is rising, posing a global threat to human health. Furthermore, science, technology, engineering and mathematics (STEM) skills are in crisis, jeopardising our capacity to mobilise as a society to fight antimicrobial resistance (AMR). Originally conceived as a response to the AMR and STEM emergencies, our project was hit by the unprecedented challenge of engaging with schools during the COVID-19 pandemic. We describe how we adapted our project to enable remote participation from primary schools and youth groups, utilising COVID-19 response initiatives as opportunities for multi-level co-creation of resources with learners in primary, secondary, and higher education. We produced portable kit boxes for soil sample collection with learning activities and videos linked to the Scottish Curriculum for Excellence. We also addressed glaring project specific content gaps relating to microbiology on English and Simple English Wikipedia. Our hybrid model of working extended our geographical reach and broadened inclusion. We present here the inception, implementation, digital resource outputs, and discussion of pedagogical aspects of 'Antibiotics under our feet'. Our strategies and insights are applicable post-pandemic for educators to develop STEM skills using soil, microbes, and antibiotics as a theme.
RESUMO
BACKGROUND: Treatment options for pre-treated patients with metastatic triple-negative breast cancer (mTNBC) remain limited. This is the first study to assess the real-world safety and efficacy of sacituzumab govitecan (SG) in the UK. METHODS: Data was retrospectively collected from 16 tertiary UK cancer centres. Pts had a diagnosis of mTNBC, received at least two prior lines of treatment (with at least one being in the metastatic setting) and received at least one dose of SG. RESULTS: 132 pts were included. Median age was 56 years (28-91). All patients were ECOG performance status (PS) 0-3 (PS0; 39, PS1; 76, PS2; 16, PS3;1). 75% (99/132) of pts had visceral metastases including 18% (24/132) of pts with CNS disease. Median PFS (mPFS) was 5.2 months (95% CI 4.5-6.6) with a median OS (mOS) of 8.7 months (95% CI 6.8-NA). The most common adverse events (AEs) were fatigue (all grade; 82%, G3/4; 14%), neutropenia (all grade; 55%, G3/4; 29%), diarrhoea (all grade; 58%, G3/4, 15%), and nausea (all grade; 38%, G3/4; 3%). SG dose reduction was required in 54% of pts. CONCLUSION: This study supports significant anti-tumour activity in heavily pre-treated pts with mTNBC. Toxicity data aligns with clinical trial experience.

BACKGROUND: The main causes of morbidity and mortality for adolescents and young adults are preventable and stem from psychosocial and behavioural concerns. Psychosocial assessments can help clinicians to identify and respond holistically to risks and strengths that may impact upon a young person's physical and mental health. Despite broad support at a policy level, the implementation of routine psychosocial screening for young people remains varied in Australian health settings. The current study focused on the pilot implementation of a digital patient-completed psychosocial assessment (the e-HEEADSSS) at the Sydney Children's Hospital Network. The aim of this research was to evaluate patient and staff barriers and facilitators to local implementation. METHODS: The research used a qualitative descriptive research design. Semi-structured interviews were conducted online with 8 young patients and 8 staff members who had completed or actioned an e-HEEADSSS assessment within the prior 5 weeks. Qualitative coding of interview transcripts was carried out in NVivo 12. The Consolidated Framework for Implementation Research guided the interview framework and qualitative analyses. RESULTS: Results demonstrated strong support for the e-HEEADSSS from patients and staff. Key reported facilitators included strong design and functionality, reduced time requirements, greater convenience, improved disclosure, adaptability across settings, greater perceived privacy, improved fidelity, and reduced stigma for young people. The key barriers were related to concerns over available resources, the sustainability and continuity of staff training, perceived availability of clinical pathways for follow-up and referrals, and risks related to off-site completions. Clinicians need to adequately explain the e-HEEADSSS assessment to patients, educate them about it, and make sure that they receive timely feedback on the results. Greater reassurance and education regarding the rigour of confidentiality and data handling procedures is required for patients and staff. CONCLUSIONS: Our findings indicate that continued work is required to support the integration and sustainability of digital psychosocial assessments for young people at the Sydney Children's Hospital Network. The e-HEEADSSS shows promise as an implementable intervention to achieve this goal. Further research is required to determine the scalability of this intervention across the broader health system.

OBJECTIVES: The debilitating nature of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) means that family members often take on a caring role. This study compared the experiences of people caring for three groups: youth, young adults, spouses. METHODS: An opportunistic sample of 36 carers completed an online survey of open-ended questions asking about their experiences. Thematic analysis was used to consider the three sets of responses separately and Thematic Comparison was used to identify points of connection and disconnection across the sets. RESULTS: The themes identified were very similar to those identified in past studies. Two super-ordinate themes were identified: "Lack of knowledge and understanding" and "Holistic Impact". Though most sub-ordinate themes were evident across all three groups, important differences were found. The sub-ordinate themes "Caring Blindly", "Emotional and physical health cost", and "Impact on the whole family" were more evident amongst carers of youth while the theme "Worry for the future" was more evident from carers of young adults and spouses. DISCUSSION: Differences seemed to be related to both the time since diagnosis and the life stage. A longitudinal study would help to understand how carer experiences change over the life course of caring for someone with ME/CFS.

AIM: Having an infant admitted to a neonatal care facility can be highly distressing for parents given the fragile state of their child and the often-unfamiliar environment. This study aimed to explore the needs and coping strategies of parents in this setting. METHODS: An online qualitative survey was used to explore the needs of parents who had a child discharged from a New Zealand neonatal unit in the past 12 months. A total of 394 parents participated in the study (387 mothers, 5 fathers), providing 970 responses across three open-ended questions examining their needs, unmet needs and coping strategies. The study included participants across both neonatal intensive care units and special care baby units, with prematurity (47%) the most common reason for admission. An inductive form of thematic analysis was used to analyse the data. RESULTS: Four themes were developed that capture the needs and coping strategies expressed by parents in this study: communication and information; physical contact and access to the baby; emotional and non-medical support; and involvement, autonomy and respect. CONCLUSIONS: The themes developed largely centre around the struggle parents face when confronting the uncertainty of the neonatal environment and the difficulty in establishing their parental role. Parental distress may be reduced through communicating accurate information regularly and providing empathetic understanding, while opportunities for physical contact and involvement may assist in raising parental confidence and scaffolding the journey to independent care of their infant.

Traditional face-to-face laboratory studies have contributed greatly to our understanding of how misinformation effects develop. However, an area of emerging concern that has been relatively under-researched is the impact of misinformation following exposure to traumatic events that are viewed online. Here we describe a novel method for investigating misinformation effects in an online context. Participants (N = 99) completed the study online. They first watched a 10-min video of a fictional school shooting. Between 5 and 10 days later, they were randomly assigned to receive misinformation or no misinformation about the video before completing a recognition test. Misinformed participants were less accurate at discriminating between misinformation and true statements than control participants. This effect was most strongly supported by ROC analyses (Cohen's d = 0.59, BF10 = 8.34). Misinformation effects can be established in an online experiment using candid violent viral-style video stimuli.
RESUMO
Objectives: Identifying genetic pathogenic variants improves clinical outcomes for children with developmental and epileptic encephalopathy (DEE) by directing therapy and enabling accurate reproductive and prognostic information for families. We aimed to explore the additional personal utility of receiving a genetic diagnosis for families. Methods: Semi-structured interviews were conducted with fifteen families of children with a DEE who had received a genetic diagnosis. The interviews stimulated discussion focusing on the impact of receiving a genetic diagnosis for the family. Interview transcripts were analyzed using the six-step systematic process of interpretative phenomenological analysis (IPA). Results: Three key themes were identified: "Importance of the label," "Relief to end the diagnostic journey," and "Factors that influence personal utility." Families reported that receiving a genetic label improved their knowledge about the likely trajectory of the DEE, increased their hope for the future, and helped them communicate with others. The relief of finally having an answer for the cause of their child's DEE alleviated parental guilt and self-blame as well as helped families to process their grief and move forward. Delay in receipt of a genetic diagnosis diluted its psychological impact. Significance: To date, the factors associated with the personal utility of a genetic diagnosis for DEEs have been under appreciated. This study demonstrates that identifying a genetic diagnosis for a child's DEE can be a psychological turning point for families. A genetic result has the potential to set these families on an adaptive path toward better quality of life through increased understanding, social connection, and support. Early access to genetic testing is important as it not only increases clinical utility, but also increases personal utility with early mitigation of family stress, trauma, and negative experiences.

Joint attention (JA) is an early manifestation of social cognition, commonly described as interactions in which an infant looks or gestures to an adult female to share attention about an object, within a positive emotional atmosphere. We label this description the JA phenotype. We argue that characterizing JA in this way reflects unexamined assumptions which are, in part, due to past developmental researchers' primary focus on western, middle-class infants and families. We describe a range of cultural variations in caregiving practices, socialization goals, and parenting ethnotheories as an essential initial step in viewing joint attention within inclusive and contextualized perspectives. We begin the process of conducting a decolonized study of JA by considering the core construct of joint attention (i.e., triadic connectedness) and adopting culturally inclusive definitions (labeled joint engagement [JE]). Our JE definitions allow for attention and engagement to be expressed in visual and tactile modalities (e.g., for infants experiencing distal or proximal caregiving), with various social partners (e.g., peers, older siblings, mothers), with a range of shared topics (e.g., representing diverse socialization goals, and socio-ecologies with and without toys), and with a range of emotional tone (e.g., for infants living in cultures valuing calmness and low arousal, and those valuing exuberance). Our definition of JE includes initiations from either partner (to include priorities for adult-led or child-led interactions). Our next foundational step is making an ecological commitment to naturalistic observations (Dahl, 2017, Child Dev Perspect, 11(2), 79-84): We measure JE while infants interact within their own physical and social ecologies. This commitment allows us to describe JE as it occurs in everyday contexts, without constraints imposed by researchers. Next, we sample multiple groups of infants drawn from diverse socio-ecological settings. Moreover, we include diverse samples of chimpanzee infants to compare with diverse samples of human infants, to investigate the extent to which JE is unique to humans, and to document diversity both within and between species. We sampled human infants living in three diverse settings. U.K. infants (n = 8) were from western, middle-class families living near universities in the south of England. Nso infants (n = 12) were from communities of subsistence farmers in Cameroon, Africa. Aka infants (n = 10) were from foraging communities in the tropical rain forests of Central African Republic, Africa. We coded behavioral details of JE from videotaped observations (taken between 2004 and 2010). JE occurred in the majority of coded intervals (Mdn = 68%), supporting a conclusion that JE is normative for human infants. The JA phenotype, in contrast, was infrequent, and significantly more common in the U.K. (Mdn = 10%) than the other groups (Mdn < 3%). We found significant within-species diversity in JE phenotypes (i.e., configurations of predominant forms of JE characteristics). We conclude that triadic connectedness is very common in human infants, but there is significant contextualization of behavioral forms of JE. We also studied chimpanzee infants living in diverse socio-ecologies. The PRI/Zoo chimpanzee infants (n = 7) were from captive, stable groups of mixed ages and sexes, and included 4 infants from the Chester Zoo, U.K. and 3 from the Primate Research Institute, Kyoto University, Japan. The Gombe chimpanzee infants (n = 12) were living in a dynamically changing, wild community in the Gombe National Park, Tanzania, Africa. Additionally, we include two Home chimpanzee infants who were reared from birth by a female scientist, in the combined U.S., middle-class contexts of home and university cognition laboratory. JE was coded from videotaped observations (taken between 1993 and 2006). JE occurred during the majority of coded intervals (Mdn = 64%), consistent with the position that JE is normative for chimpanzee infants. The JA phenotype, in contrast, was rare, but more commonly observed in the two Home chimpanzee infants (in 8% and 2% of intervals) than in other chimpanzee groups (Mdns = 0%). We found within-species diversity in the configurations comprising the JE phenotypes. We conclude that triadic connectedness is very common in chimpanzee infants, but behavioral forms of joint engagement are contextualized. We compared JE across species, and found no species-uniqueness in behavioral forms, JE characteristics, or JE phenotypes. Both human and chimpanzee infants develop contextualized social cognition. Within-species diversity is embraced when triadic connectedness is described with culturally inclusive definitions. In contrast, restricting definitions to the JA phenotype privileges a behavioral form most valued in western, middle-class socio-ecologies, irrespective of whether the interactions involve human or chimpanzee infants. Our study presents a model for how to decolonize an important topic in developmental psychology. Decolonization is accomplished by defining the phenomenon inclusively, embracing diversity in sampling, challenging claims of human-uniqueness, and having an ecological commitment to observe infant social cognition as it occurs within everyday socio-ecological contexts. It is essential that evolutionary and developmental theories of social cognition are re-built on more inclusive and decolonized empirical foundations.

BACKGROUND: Adolescents and young adults (AYAs; 16-25 years old) with cancer may be particularly affected by social interactions, as they can be grappling with a serious illness and normal developmental challenges. OBJECTIVES: The aims of this study were to explore interactions relevant to AYA survivors and cancer and to investigate whether specific interactions are experienced as more and less helpful. METHODS: Ten semistructured interviews were conducted with AYAs, with questions pertaining to their psychosocial interactions and any developmental effects from having cancer. Five follow-up interviews were conducted approximately 12 months later, a 50% response rate. RESULTS: Thematic analysis identified a range of themes including the importance of personal privacy and controlled sharing of information, independence, identity formation, positivity, acknowledgement of cancer versus being treated normally, and receiving support instead of supporting others. In the 1-year follow-up interviews, half of these themes remained constant; however, the personal privacy, independence, and supporting others themes changed. CONCLUSIONS: Overall, social support, social interactions, and developmental stage seem to influence the overall cancer experience. Development seems to be impacted by cancer for both adolescents and young adults, but this impact lessened over a 1-year period for the 50% of participants who participated in both interviews. IMPLICATIONS FOR PRACTICE: It is believed that a more comprehensive understanding of AYA patients' psychosocial experiences related to cancer will enable those who interact with this group to provide more positive support through their interactions with individuals.

BACKGROUND: Qualitative literature on the experiences of those delivering and receiving bad news about cancer has revealed what these parties consider important during the process across many different patient cases. The current study aims to add to this understanding by employing a "linked case" study design to directly compare the perspectives of patients, their caregivers, and health care professionals (HCPs) involved in a series of single-patient cases of breaking bad news. METHOD: Semistructured interviews were conducted with 13 participants (5 patients, 4 caregivers, 2 surgeons, and 2 nurses) who formed 5 linked cases. Interviews were analyzed using interpretative phenomenological analysis and directly compared within each linked case. RESULTS: Analyses identified 2 main superordinate themes. The first labeled "accurately perceiving and responding to needs," included HCPs recognizing and responding to patients' and caregivers' individual emotional and informational needs. The second labeled "carers fulfilling necessary roles," identified the various roles HCPs and patients' caregivers took to satisfactorily meet patients' needs. CONCLUSIONS: The findings suggest the importance of HCPs accurately perceiving and responding to patients' and caregivers' various needs and caregivers ability and willingness to fulfilling support roles in a way that aligns with their own resources and patients' needs. This highlights the value of HCPs developing and applying interpersonal skills within bad news encounters, working as a team, and exploring caregivers' resources for patient support.
RESUMO
OBJECTIVE: This qualitative meta-synthesis explored the subjective experiences of patients and their family members when receiving bad news about cancer, with a focus on what was important to them during this process and making future recommendations. METHODS: A search of five electronic databases yielded 587 different records that resulted in 88 articles assessed against the inclusion/exclusion criteria. With the supplement of four additional records, 29 articles were analysed using thematic synthesis. A quality appraisal checklist was used to provide further information about the included articles. RESULTS: Patients and family members experienced receiving bad news as a process that involved three phases, labelled as follows: "preparation", "delivery", and "adjusting and coping". The "preparation" phase had four themes: the setting, developing a relationship, knowing the patient, and forewarning. Four themes were identified during the "delivery" phase: emotional reactions, empathy not sympathy, active participation, and understanding. "Adjusting and coping" comprised four themes: hope, holistic support, being a protector, and ongoing relationships. CONCLUSIONS: Receiving bad news is a significant experience for patients and family members. They want bad news delivered in an appropriate setting, in a manner consistent with their personal preferences, and have their psychological needs attended to within the context of an established relationship. Healthcare professionals can be assisted to deliver bad news in the best way possible by additional training and their workplace institutions providing quiet, private rooms, and sufficient time. Future research is needed to better understand family members' experiences and needs.

Objectives: We have previously shown mitogen-activated protein kinase phosphatase 2 (MKP-2) to be a key regulator of proinflammatory cytokines in macrophages. In the study presented here, we investigated the role of MKP-2 in inflammatory arthritis with a particular focus on neutrophils. Methods: To achieve this, we subjected MKP-2 deficient and wild type mice to collagen antibody induced arthritis, an innate model of arthritis, and determined disease pathology. To further our investigation, we depleted neutrophils in a prophylactic and therapeutic fashion. Last, we used chemotaxis assays to analyse the impact of MKP-2 deletion on neutrophil migration. Results: MKP-2-/- mice showed a significant increase in disease pathology linked to elevated levels of proarthritic cytokines and chemokines TNF-α, IL-6 and MCP-1 in comparison to wild type controls. This phenotype is prevented or abolished after administration of neutrophil depleting antibody prior or after onset of disease, respectively. While MCP-1 levels were not affected, neutrophil depletion diminished TNF-α and reduced IL-6, thus linking these cytokines to neutrophils. In vivo imaging showed that MKP-2-/- mice had an increased influx of neutrophils into affected joints, which was higher and potentially prolonged than in wild type animals. Furthermore, using chemotaxis assays we revealed that MKP-2 deficient neutrophils migrate faster towards a Leukotriene B4 gradient. This process correlated with a reduced phosphorylation of ERK in MKP-2-/- neutrophils. Conclusions: This is the first study to show a protective role for MKP-2 in inflammatory arthritis.

The immune system has long been known to play a critical role in the body's defence against cancer, and there have been multiple attempts to harness it for therapeutic gain. Renal cancer was, historically, one of a small number of tumour types where immune manipulation had been shown to be effective. The current generation of immune checkpoint inhibitors are rapidly entering into routine clinical practice in the management of a number of tumour types, including renal cancer, where one drug, nivolumab, an anti-programmed death-1 (PD-1) monoclonal antibody (mAb), is licensed for patients who have progressed on prior systemic treatment. Ongoing trials aim to maximize the benefits that can be gained from this new class of drug by exploring optimal timing in the natural course of the disease as well as combinations with other checkpoint inhibitors and drugs from different classes.

The duration and magnitude of clinical response are unpredictable in ALK-rearranged non-small cell lung cancer (NSCLC) patients treated with crizotinib, although all patients invariably develop resistance. Here, we evaluated whether circulating tumor cells (CTC) with aberrant ALK-FISH patterns [ALK-rearrangement, ALK-copy number gain (ALK-CNG)] monitored on crizotinib could predict progression-free survival (PFS) in a cohort of ALK-rearranged patients. Thirty-nine ALK-rearranged NSCLC patients treated with crizotinib as first ALK inhibitor were recruited prospectively. Blood samples were collected at baseline and at an early time-point (2 months) on crizotinib. Aberrant ALK-FISH patterns were examined in CTCs using immunofluorescence staining combined with filter-adapted FISH after filtration enrichment. CTCs were classified into distinct subsets according to the presence of ALK-rearrangement and/or ALK-CNG signals. No significant association between baseline numbers of ALK-rearranged or ALK-CNG CTCs and PFS was observed. However, we observed a significant association between the decrease in CTC number with ALK-CNG on crizotinib and a longer PFS (likelihood ratio test, P = 0.025). In multivariate analysis, the dynamic change of CTC with ALK-CNG was the strongest factor associated with PFS (HR, 4.485; 95% confidence interval, 1.543-13.030, P = 0.006). Although not dominant, ALK-CNG has been reported to be one of the mechanisms of acquired resistance to crizotinib in tumor biopsies. Our results suggest that the dynamic change in the numbers of CTCs with ALK-CNG may be a predictive biomarker for crizotinib efficacy in ALK-rearranged NSCLC patients. Serial molecular analysis of CTC shows promise for real-time patient monitoring and clinical outcome prediction in this population. Cancer Res; 77(9); 2222-30. ©2017 AACR.

Touch screen storybooks turn reading into an interactive multimedia experience, with hotspot-activated animations, sound effects, and games. Positive and negative effects of reading multimedia stories have been reported, but the underlying mechanisms which explain how children's learning is affected remain uncertain. The present study examined the effect of storybook format (touch screen and print) on story comprehension, and considered how level of touch screen interactivity (high and low) and shared reading behaviors (cognitive and emotional scaffolding, emotional engagement) might contribute to comprehension. Seven-year-olds (n = 22) were observed reading one touch screen storybook and one print storybook with their mothers. Story comprehension was inferior for the touch screen storybooks compared to the print formats. Touch screen interactivity level had no significant effect on comprehension but did affect shared reading behaviors. The mother-child dyads spent less time talking about the story in the highly interactive touch screen condition, despite longer shared reading sessions because of touch screen interactions. Positive emotional engagement was greater for children and mothers in the highly interactive touch screen condition, due to additional positive emotions expressed during touch screen interactions. Negative emotional engagement was greater for children when reading and talking about the story in the highly interactive condition, and some mothers demonstrated negative emotional engagement with the touch screen activities. The less interactive touch screen storybook had little effect on shared reading behaviors, but mothers controlling behaviors were more frequent. Storybook format had no effect on the frequency of mothers' cognitive scaffolding behaviors (comprehension questions, word help). Relationships between comprehension and shared reading behaviors were examined for each storybook, and although length of the shared reading session and controlling behaviors had significant effects on comprehension, the mechanisms driving comprehension were not fully explained by the data. The potential for touch screen storybooks to contribute to cognitive overload in 7-year-old developing readers is discussed, as is the complex relationship between cognitive and emotional scaffolding behaviors, emotional engagement, and comprehension. Sample characteristics and methodological limitations are also discussed to help inform future research.
RESUMO
Previous research has highlighted that acute care provision can lead to a loss of confidence, control, and independent functioning in older adult patients. In addition, it is recognized that interactions between patients and health care staff are central to the prevention of functional decline in patients. In this study, we aimed to affect the staff-patient relationship by implementing a coaching intervention in an older adult acute care setting. Here, we report on staff experiences of this coaching approach. Data were collected from 16 members of staff via semi-structured interviews, which were analyzed using thematic analysis. Four themes were identified: Putting a Label on It, Stepping Back and Listening, Identifying the Opportunities, and Working as Team. Our findings show that a coaching approach can be successful in getting staff to reconsider their interactions with patients and to focus on strategies that foster the independence and autonomy of older adult patients.

OBJECTIVE: In the present study we evaluated the use of four commercially available fluorescent probes to monitor disease activity in murine CIA and its suppression during glucocorticoid therapy. METHODS: Arthritis was induced in male DBA/1 mice by immunization with type II collagen in Complete Freund's Adjuvant, followed by a boost of collagen in PBS. Four fluorescent probes from PerkinElmer in combination [ProSense 750 fluorescent activatable sensor technology (FAST) with Neutrophil Elastase 680 FAST and MMPSense 750 FAST with CatK 680 FAST] were used to monitor disease development from day 5 through to day 40 post-immunization. Fluorescence generated in vivo by the probes was correlated with clinical and histological score and paw measurements. RESULTS: The fluorescence intensity emitted by each probe was shown to correlate with the conventional measurements of disease. The highest degree of correlation was observed with ProSense 750 FAST in combination with Neutrophil Elastase 680 FAST; these probes were then used to successfully assess CIA suppression during dexamethasone treatment. CONCLUSION: We have demonstrated that longitudinal non-invasive duplexed optical fluorescence imaging provides a simple assessment of arthritic disease activity within the joints of mice following the induction of CIA and may represent a powerful tool to monitor the efficacy of drug treatments in preclinical studies.

In non-small-cell lung cancer (NSCLC), genotyping tumor biopsies for targetable somatic alterations has become routine practice. However, serial biopsies have limitations: they may be technically difficult or impossible and could incur serious risks to patients. Circulating tumor cells (CTCs) offer an alternative source for tumor analysis that is easily accessible and presents the potential to identify predictive biomarkers to tailor therapies on a personalized basis. Examined here is our current knowledge of CTC detection and characterization in NSCLC and their potential role in EGFR-mutant, ALK-rearranged and ROS1-rearranged patients.

Knowledge of the context and development of playful expressions in chimpanzees is limited because research has tended to focus on social play, on older subjects, and on the communicative signaling function of expressions. Here we explore the rate of playful facial and body expressions in solitary and social play, changes from 12- to 15-months of age, and the extent to which social partners match expressions, which may illuminate a route through which context influences expression. Naturalistic observations of seven chimpanzee infants (Pan troglodytes) were conducted at Chester Zoo, UK (n = 4), and Primate Research Institute, Japan (n = 3), and at two ages, 12 months and 15 months. No group or age differences were found in the rate of infant playful expressions. However, modalities of playful expression varied with type of play: in social play, the rate of play faces was high, whereas in solitary play, the rate of body expressions was high. Among the most frequent types of play, mild contact social play had the highest rates of play faces and multi-modal expressions (often play faces with hitting). Social partners matched both infant play faces and infant body expressions, but play faces were matched at a significantly higher rate that increased with age. Matched expression rates were highest when playing with peers despite infant expressiveness being highest when playing with older chimpanzees. Given that playful expressions emerge early in life and continue to occur in solitary contexts through the second year of life, we suggest that the play face and certain body behaviors are emotional expressions of joy, and that such expressions develop additional social functions through interactions with peers and older social partners.
