Observational learning of tool use in children: Investigating cultural spread through diffusion chains and learning mechanisms through ghost displays

In the first of two experiments, we demonstrate the spread of a novel form of tool use across 20 “cultural generations” of child-to-child transmission. An experimentally seeded technique spread with 100% fidelity along twice as many “generations” as has been investigated in recent exploratory “diffusion” experiments of this type. This contrasted with only a single child discovering the technique spontaneously in a comparable group tested individually without any model. This study accordingly documents children’s social learning of tool use on a new, population-level scale that characterizes real-world cultural phenomena. In a second experiment, underlying social learning processes were investigated with a focus on the contrast between imitation (defined as copying actions) and emulation (defined as learning from the results of actions only). In two different “ghost” conditions, children were presented with the task used in the first experiment but now operated without sight of an agent performing the task, thereby presenting only the information used in emulation. Children in ghost conditions were less successful than those who had watched a model in action and showed variable matching to what they had seen. These findings suggest the importance of observational learning of complex tool use through imitation rather than only through emulation. Results of the two experiments are compared with those of similar experiments conducted previously with chimpanzees and are discussed in relation to the wider perspective of human culture and the influence of task complexity on social learning.     

When and how social movements mobilize action within and across nations to promote solidarity with refugees

When and how do social movements form to mobilize action across national boundaries? In the context of the 2015 movement to support Syrian refugees, we develop an integrative model of transnational social movement formation shaped by pre-existing world-views (social dominance orientation and right-wing authoritarianism) and social media exposure to iconic events, resulting in an emergent group consciousness (“we are”, “we believe”, “we feel”). Group consciousness is, in turn, the proximal predictor of solidarity with refugees. Participants were from six countries: Hungary (N = 267), Romania (N = 163), Germany (N = 190), the United Kingdom (N = 159), the United States (N = 244) and Australia (N = 344). Multi-group structural equation models confirmed that group consciousness, shaped by individual differences and exposure to events through social media, was the proximal predictor of solidarity. The subjective meaning of group consciousness varied across samples, reflecting national differences. Results support the importance of considering individual and national differences, and group processes in understanding emergent social movements.     

A client‐generated psychometric instrument: The development of ‘PSYCHLOPS’

PSYCHLOPS (Psychological Outcome Profiles) is a recently developed, client‐generated, psychometric instrument that can be used as an outcome measure. Based on a similar instrument developed primarily for use in physical illnesses (MYMOP — ‘Measure Your Medical Outcome Profile’), it seeks the client's perspective on their psychological distress. It asks them to describe and then score the problem that troubles them the most at the start of counselling. We describe the development of PSYCHLOPS, including the involvement of the Plain English Campaign and two national mental health organisations: the mental health charity and support group, Depression Alliance (DA) and Primary Care Mental Health Education (PRIMHE). We review the literature and suggest that PSYCHLOPS, by focusing on the problems of greatest priority to the client, might prove a sensitive measure of improvement after counselling.     

When causality shapes the experience of time: Evidence for temporal binding in young children

It is well established that the temporal proximity of two events is a fundamental cue to causality. Recent research with adults has shown that this relation is bidirectional: events that are believed to be causally related are perceived as occurring closer together in time—the so‐called temporal binding effect. Here, we examined the developmental origins of temporal binding. Participants predicted when an event that was either caused by a button press, or preceded by a non‐causal signal, would occur. We demonstrate for the first time that children as young as 4 years are susceptible to temporal binding. Binding occurred both when the button press was executed via intentional action, and when a machine caused it. These results suggest binding is a fundamental, early developing property of perception and grounded in causal knowledge.

The relationship between biological and psychosocial risk factors and resting‐state functional connectivity in 2‐month‐old Bangladeshi infants: A feasibility and pilot study

Childhood poverty has been associated with structural and functional alterations in the developing brain. However, poverty does not alter brain development directly, but acts through associated biological or psychosocial risk factors (e.g. malnutrition, family conflict). Yet few studies have investigated risk factors in the context of infant neurodevelopment, and none have done so in low‐resource settings such as Bangladesh, where children are exposed to multiple, severe biological and psychosocial hazards. In this feasibility and pilot study, usable resting‐state fMRI data were acquired in infants from extremely poor (n = 16) and (relatively) more affluent (n = 16) families in Dhaka, Bangladesh. Whole‐brain intrinsic functional connectivity (iFC) was estimated using bilateral seeds in the amygdala, where iFC has shown susceptibility to early life stress, and in sensory areas, which have exhibited less susceptibility to early life hazards. Biological and psychosocial risk factors were examined for associations with iFC. Three resting‐state networks were identified in within‐group brain maps: medial temporal/striatal, visual, and auditory networks. Infants from extremely poor families compared with those from more affluent families exhibited greater (i.e. less negative) iFC in precuneus for amygdala seeds; however, no group differences in iFC were observed for sensory area seeds. Height‐for‐age, a proxy for malnutrition/infection, was not associated with amygdala/precuneus iFC, whereas prenatal family conflict was positively correlated. Findings suggest that it is feasible to conduct infant fMRI studies in low‐resource settings. Challenges and practical steps for successful implementations are discussed.     

From “I” to “We”: Different forms of identity,emotion, and belief predict victim support volunteerism among nominal and active supporters

Understanding how to attract and maintain volunteers is crucial for the operation of victim support organizations. We propose that volunteerism can be understood in a similar way as collective action. Active (N = 99) and nominal supporters (N = 134) completed measures of identities (personal, social, and organizational), emotions (sympathy, outrage, and pride), and efficacy beliefs (self‐, group, and organizational). The results revealed a different pattern of predictors of volunteerism for the two samples. Among nominal supporters, commitment to volunteerism was predicted by personal identity (“I”), sympathy, and self‐efficacy; among the actively engaged, volunteerism was predicted by social identity (“we”), outrage, and self‐efficacy. These results suggest that engagement with volunteerism is associated with qualitatively different processes for those nominally versus actively supportive of volunteer efforts.     

The impact of the “Attachment and Biobehavioural Catch-Up” program on attachment related parent behavior—A systematic review

“Attachment and Biobehavioural Catch-Up” (ABC) is a 10 session home visiting program, grounded in attachment theory. It aims to improve child emotion regulation, attachment and behavioral outcomes through changing caregivers’ attachment related behaviors. There is increasing evidence with respect to the effectiveness of ABC in producing positive child outcomes, but the intervention's direct effect on parent outcomes remains unclear. This review examined the association of ABC with attachment related parent outcomes. The PubMed, EMBASE, PyschINFO and SCOPUS databases were searched for relevant studies in August 2021, and again in April 2022. The eligibility criteria for included studies were (1) infants aged 0–27 months at time of the ABC intervention, (2) “at risk” parents, (3) controlled trials published in peer-reviewed journals and (4) utilized a measure of attachment related parent outcomes. Eleven eligible studies were included. The findings showed ABC had a significant small to medium effect on a variety of attachment related parent outcomes among parents presenting with multiple psychosocial risk factors. “Sensitivity” was measured most frequently, with small to medium main effect sizes recorded at follow-up, compared to controls. Implications for the clinical effectiveness of the ABC program in community settings are discussed. Future research should clarify who ABC is most effective for and how it compares to similar interventions.     

An evaluation of Headsprout early reading as an online parent-mediated intervention for primary school children

Due to the Coronavirus pandemic and lengthy absences from the classroom, there is a need for large-scale remedial programs to support young children to “catch-up” on literacy and numeracy skills. A stratified randomized controlled trial was used to evaluate the Headsprout Early Reading (HER) program as a parent-mediated digital literacy intervention. A between-groups design compared differences in reading-dependent outcome measures for 36 children assigned to one of three intervention groups: with support, without support, and waitlist-control. Children completed significantly more episodes when parents received implementation support from the researcher compared to the without support group. Children receiving Headsprout instructions demonstrated marginally greater gains than the waitlist-control group in posttest outcome measures; however, differences in reading outcomes were not significant between groups at posttesting. The current research provides tentative support for HER and importantly, highlights the importance of providing support for parents implementing interventions at home.
