How to Create Shared Symbols

Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual‐level account, based on observational learning and cognitive bias, with an inter‐individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual‐level learning, via observation and cognitive bias, was sufficient to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter‐individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols.     

Shared intentionality

We argue for the importance of processes of shared intentionality in children's early cognitive development. We look briefly at four important social-cognitive skills and how they are transformed by shared intentionality. In each case, we look first at a kind of individualistic version of the skill -- as exemplified most clearly in the behavior of chimpanzees -- and then at a version based on shared intentionality -- as exemplified most clearly in the behavior of human 1- and 2-year-olds. We thus see the following transformations: gaze following into joint attention, social manipulation into cooperative communication, group activity into collaboration, and social learning into instructed learning. We conclude by highlighting the role that shared intentionality may play in integrating more biologically based and more culturally based theories of human development.     

Developmental path between language and autistic‐like impairments: a twin study

Autism spectrum disorders (ASDs) are diagnosed when individuals show impairments in three behavioural domains: communication, social interactions, and repetitive, restrictive behaviours and interests (RRBIs). Recent data suggest that these three sets of behaviours are genetically heterogeneous. Early language delay is strongly associated with ASD, but the basis for this association and the relationship with individual sub‐domains of ASD has not been systematically investigated. In the present study, data came from a population‐based twin sample with language development data at 2–4 years, measured by the MacArthur Communicative Development Inventory (MCDI), and data at 8 years using the Childhood Asperger Syndrome Test (CAST). For the total CAST and the three subscales at 8 years, approximately 300 same‐sex twin pairs were selected as showing extreme autistic‐like traits (ALTs), defined here as pairs in which at least one member of the twin pair scored in the highest 5% of the distribution. Phenotypic analyses indicated that children showing extreme social and communication ALTs (but not the RRBI subscale) at 8 years were below average in language development at 2–4 years. A regression model for selected twin data suggested that genetic influences account for this overlap, but that these effects are only in part mediated by genes that are shared between language and extreme autistic traits.

Conceptual constraints and mechanisms in children's selective learning

Although we can support Heyes’ call for more research on mechanisms, we disagree that the problem has been ignored as Heyes suggests. We also doubt that basic learning mechanisms are alone sufficient to account for the broad range of findings in the selective social learning literature. Although phylogenetically shared learning mechanisms must support selective social learning, we believe that they must also be guided by top‐down conceptual considerations that may be special to humans. Research to date has been focused on establishing the boundary conditions on selective social learning, with the goal of making generalizations that will constrain theorizing about the character of that special knowledge. This is critical to our understanding of both why and how selective social learning manifests in children.     

Naming and categorization in young children: v. manual sign training

Following pre-training with everyday objects, 8 children aged from 2 to 4 years learned to produce one manual sign (fists placed one above the other, in front of body) to one stimulus and an alternative manual sign (shoulders touched with ipsilateral hands) to the other stimulus, with each of three pairs of different arbitrary wooden shapes (Set 1). The six stimuli then were presented in category match-to-sample tests, which all subjects passed. Three of the children were next trained to produce the manual signs (denoted as fist/shoulder) for an additional six arbitrary stimuli, Set 2. All 3 children went on to pass category match-to-sample tests for Set 2, and for Set 1 and Set 2 combined. In the final experimental phase, 2 of the children were trained, for one of the six stimulus pairs, to produce the vocal tact "zag" to one stimulus and "vek" to the other. Both children showed category transfer of these vocalizations in test trials with each of the remaining five stimulus pairs, and all the stimuli combined in a 12-stimulus array. In line with Horne and Lowe's (1996) naming account, manual sign naming was found to be as effective as vocal naming in establishing arbitrary stimulus categorization, measured in terms of category sorting and transfer of function. The findings also have implications for the training of verbal repertoires in people with learning disabilities.     

Rethinking Collaborative Learning Through Participation in an Interdisciplinary Research Project: Tensions and Negotiations as Key Points in Knowledge Production

As social and cultural psychologists of learning, we are persuaded of the crucial role of interaction in development and learning. But how do we experience this assumption in our own research practices and in our collaboration with colleagues? Taking as our object of study our own participation in a European Research and Development project that aimed to enhance interactive and argumentative skills in learning settings, this study shows how collaboration among project partners is not something that is to be taken for granted, but something that is elaborated and evolves in time, takes diverse forms, and is mediated by multiple tools. The psychological processes—more particularly tensions and negotiation—involved in collaboration are developed and discussed. The study explores the processes of establishing collaboration and, through the analysis of specific zones of tensions, sheds light on the way new knowledge (on how to do research, how to communicate, how to work together) is constructed. It contributes to the understanding of the issues and conditions for the development of a community of practice.     

Abstract-concept learning in Black-billed magpies (<Emphasis Type="Italic">Pica hudsonia</Emphasis>)

Abstract relational concepts depend upon relationships between stimuli (e.g., same vs. different) and transcend features of the training stimuli. Recent evidence shows that learning abstract concepts is shared across a variety species including birds. Our recent work with a highly-skilled food-storing bird, Clark’s nutcracker, revealed superior same/different abstract-concept learning compared to rhesus monkeys, capuchin monkeys, and pigeons. Here we test a more social, but less reliant on food-storing, corvid species, the Black-billed magpie (Pica hudsonia). We used the same procedures and training exemplars (eight pairs of the same rule, and 56 pairs of the different rule) as were used to test the other species. Magpies (n = 10) showed a level of abstract-concept learning that was equivalent to nutcrackers and greater than the primates and pigeons tested with these same exemplars. These findings suggest that superior initial abstract-concept learning abilities may be shared across corvids generally, rather than confined to those strongly reliant on spatial memory.     

Do children need to learn to collaborate?: The effect of age and age differences on collaborative recall

We used a collaborative recall task to explore the nature and consequences of children's interaction with another child at the same or different age. Ninety-six children memorised word lists for recall. In a first condition children recalled collaboratively: in a pair with another child. In a second condition children recalled words independently (this made possible the creation of “nominal” pairs for comparison). Pairs were either composed of two 7-year-olds, two 9-year-olds, or a 7- and a 9-year-old. Older pairs, like adults, showed a net negative effect of collaborative recall. However, younger children showed no effects of collaboration. Analyses of the different contributions offered by each child in a pair, and of measures of social dominance suggest that older children dominate social aspects of interaction and recall when paired with a younger child. We argue that younger children may lack full awareness of the role of interaction as a forum for the co-construction of knowledge.     

Parent-School and Community Partnerships in Children's Mental Health: Networking Challenges, Dilemmas, and Solutions

Inter-agency collaboration, service coordination, and the creation of successful partnerships among parents, teachers, and human services professionals continues to be a challenge for the development of responsive community-based systems of care for at-risk youth and their families. We explore how one inner-city neighborhood struggles to create successful community partnerships through traditional networking strategies. Our findings identify networking strategies that appear to work and those that do not. Recommendations for improving communication are provided.     

Creating a Public Space through Service‐Learning

In this paper, I suggest that community‐based learning can act as a “public space” for the exchange of religious and non‐religious identities. By providing a space for the collaboration between religiously‐affiliated Universities and non‐religiously affiliated community partners, community‐based learning offers the opportunity for the negotiation of what civic engagement means in a pluralistic society. This exchange can inform the conversation on the public role of religion by offering an example of how religious and secular communities can discover a common language through the realization of shared interests.     

The Family in Us: Family History,Family Identity and Self-Reproductive Adaptive Behavior

This contribution is an essay about the notion of family identity reflecting shared significant experiences within a family system originating a set of signs used in social communication within and between families. Significant experiences are considered as experiences of events that have an immediate impact on the adaptation of the family in a given socio-ecological and cultural context at a given historical time. It is assumed that family history is stored in a shared “family memory” holding both implicit and explicit knowledge and exerting an influence on the behavior of each family member. This is described as transgenerational family memory being constituted of a system of meaningful signs. The crucial dimension underlying the logic of this essay are the ideas of adaptation as well as self-reproduction of systems.     

On Bridging the Communication Gap

While we endorse recent calls for greater collaboration between mass communication and interpersonal communication researchers, in this response we delineate four factors that account for the relative lack of integration of these two areas of communication inquiry. The social policy focus of mass communication research, the high level of public concern over media effects, a variety of methodological cleavages, and different cognate field referents are cited as forces that support segregation of the two research areas. The recent turn to cognitive explanations of communication in both of these domains may create the climate necessary for meaningful collaboration between researchers.     

Yup’ik Culture and Context in Southwest Alaska: Community Member Perspectives of Tradition,Social Change,and Prevention

This paper provides an introduction to key aspects of Yup’ik Inuit culture and context from both historical and contemporary community member perspectives. Its purpose is to provide a framework for understanding the development and implementation of a prevention initiative centered on youth in two communities in Southwest Alaska as part of collaboration with the University of Alaska Fairbanks and the National Institutes of Health. This paper is written from the perspective of elders and local prevention workers from each of the two prevention communities. The co-authors discuss their culture and their community from their own perspectives, drawing from direct experience and from ancestral knowledge gained through learning and living the Yuuyaraq or the Yup’ik way of life. The authors of this paper identity key aspects of traditional Yup’ik culture that once contributed to the adaptability and survivability of their ancestors, particularly through times of hardship and social disruption. These key processes and practices represent dimensions of culture in a Yup’ik context that contribute to personal and collective growth, protection and wellbeing. Intervention development in Yup’ik communities requires bridging historical cultural frames with contemporary contexts and shifting focus from reviving cultural activities to repairing and revitalizing cultural systems that structure community.     

Criminal Justice and Community Psychology: Our Values and Our Work—The Introduction to the Special Issue

This special issue of The American Journal of Community Psychology originated from the Society for Community Research and Action Criminal Justice interest group, with a goal of exploring the work of community psychologists intersecting with criminal justice research, practice, and policy and shaped by our shared values—equity, collaboration, creative maladjustment, social justice, and social science in the service of social justice. In this introduction, we discuss the socio‐historical context of the special issue, followed by an outline of the special issue organization, and brief summary of the included papers. Across 13 papers and an invited commentary, we see the ways in which community psychologists are: (1) delivering and evaluating services, programming, or other supports to address the needs of system‐involved people; and (2) working to improve the systems, structures, and interactions with units of criminal justice systems. Across these two sections, authors highlight the guiding role of our values to influence change within and outside of criminal‐legal systems.     

Speech‐evoked auditory brainstem responses reflect familial and cognitive influences

Cortical function and related cognitive, language, and communication skills are genetically influenced. The auditory brainstem response to speech is linked to language skill, reading ability, cognitive skills, and speech‐in‐noise perception; however, the impact of shared genetic and environmental factors on the response has not been investigated. We assessed auditory brainstem responses to speech presented in quiet and background noise from (1) 23 pairs of same sex, same learning diagnosis siblings (Siblings), (2) 23 unrelated children matched on age, sex, IQ, and reading ability to one of the siblings (Reading‐Matched), and (3) 22 pairs of unrelated children matched on age and sex but not on reading ability to the same sibling (Age/Sex‐Matched). By quantifying response similarity as the intersubject response‐to‐response correlation for sibling pairs, reading‐matched pairs, and age‐ and sex‐matched pairs, we found that siblings had more similar responses than age‐ and sex‐matched pairs and reading‐matched pairs. Similarity of responses between siblings was as high as the similarity of responses collected from an individual over the course of the recording session. Responses from unrelated children matched on reading were more similar than responses from unrelated children matched only on age and sex, supporting previous data linking variations in auditory brainstem activity with variations in reading ability. These results suggest that auditory brainstem function can be influenced by siblingship and auditory‐based communication skills such as reading, motivating the use of speech‐evoked auditory brainstem responses for assessing risk of reading and communication impairments in family members.     

Building contexts that support effective community responses to HIV/AIDS: a South African case study

In this paper we discuss our conceptualisation of a 'health-enabling social environment', and some of the strategies we are currently using to build social contexts most likely to support effective HIV/AIDS management in southern Africa. In developing these ideas, we draw on our on-going collaboration with residents of Entabeni, a remote rural community in South Africa where 43% of pregnant women are HIV positive. The aim of this collaboration is to facilitate contextual changes that will enable more effective community-led HIV/AIDS management in an isolated area where people have little or no access to formal health or welfare support, and where HIV/AIDS is heavily stigmatised. We give an account of the three phases of collaboration to date. These include research; the dissemination of findings and community consultation about the way forward; preliminary project activities (skills training for volunteer health workers; partnership building and a youth rally) as a way of illustrating what we believe are six key strategies for facilitating the development of 'AIDS-competent' communities: building knowledge and basic skills; creating social spaces for dialogue and critical thinking; promoting a sense of local ownership of the problem and incentives for action; emphasising community strengths and resources; mobilising existing formal and informal local networks; and building partnerships between marginalized communities and more powerful outside actors and agencies, locally, nationally and internationally. We discuss some of the triumphs and trials of this work, concluding with a discussion of the need to set realistic goals when working at the community level in highly conservative patriarchal communities to tackle problems which may be shaped by economic and political processes over which local people have little control.     

The development of category learning strategies: What makes the difference?

Category learning can be achieved by identifying common features among category members, distinctive features among non-members, or both. These processes are psychologically and computationally distinct, and may have implications for the acquisition of categories at different hierarchical levels. The present study examines an account of children’s difficulty in acquiring categories at the subordinate level grounded on these distinct comparison processes. Adults and children performed category learning tasks in which they were exposed either to pairs of objects from the same novel category or pairs of objects from different categories. The objects were designed so that for each category learning task, two features determined category membership whereas two other features were task irrelevant. In the learning stage participants compared pairs of objects noted to be either from the same category or from different categories. Object pairs were chosen so that the objective amount of information provided to the participants was identical in the two learning conditions. We found that when presented only with object pairs noted to be from the same category, young children (6 ? YO ? 9.5) learned the novel categories just as well as older children (10 ? YO ? 14) and adults. However, when presented only with object pairs known to be from different categories, unlike older children and adults, young children failed to learn the novel categories. We discuss cognitive and computational factors that may give rise to this comparison bias, as well as its expected outcomes.     

Essential Elements for Community Engagement in Evidence-Based Youth Violence Prevention

In the field of youth violence prevention, there has been increasing emphasis on “evidence based” programs and principles shown through scientific research as reaching their intended outcomes. Community mobilization and engagement play a critical role in many evidence‐based programs and strategies, as it takes a concerted effort among a wide range of people within a community to alter behavior and maintain behavioral change. How do concerned individuals and groups within a community engage others within and outside of that community to effectively plan, develop and implement appropriate EB programs as well as evaluate the outcomes and impacts of locally developed programs yet to be proven? The authors discuss five elements essential for community engagement in evidence‐based youth violence prevention based on their work in a university‐community partnership through the Asian/Pacific Islander Youth Violence Prevention Center (API Center), a National Academic Center for Excellence on Youth Violence Prevention Center supported by the Centers for Disease Control and Prevention. They include: (a) aligning EBPs with a community's shared vision and values; (b) establishing an inclusive environment for the planning, implementation and evaluation of EBPs; (c) nurturing collaboration for increased effectiveness and efficacy of EBPs; (d) building adequate leadership and community capacity to develop and sustain EBPs; and (e) building a learning community for evaluation and self‐reflection. The authors propose placing greater emphasis on “evaluative thinking” and organizational capacity for evaluation as we pursue evidence‐based practices for youth violence prevention. This is especially important for ethnic groups for which an evidence base is not well established.     

Evolutionary Guidance System: A Community Design Project

The Evolutionary Guidance System (EGS) is a holistic and inclusive model for designing self-organizing social systems. Such a model must be driven by evolutionary values articulated by the members of the system. The small community is an ideal context for the "growing" of an Evolutionary Guidance System. This paper describes the creation of an EGS in a community organization. The rational for the activity is to bring harmony and build community among the members of the organization and, at the same time, to reach out and include the larger community. This organization can provide a model for other organizations in the town, and the ultimate goal is to install an EGS as a nongovernmental design system for the town.     

On Community Leadership: Stories About Collaboration in Action Research

This article provides an account of a 10-year collaborative documentation of community leadership in an African American community on the South side of Chicago. The stories are oriented to several critical incidents in the life course of the collaboration. They are told from the perspectives of one university professor, four graduate students, and one community leader. Together they provide an account of how this research was shaped by the interactions of the research team with members of the community, how research questions emerged, methodologies were developed, ways of gathering data were tried and tested, and interpretations of data unfolded. Special attention is given to the ways in which the process and products of this research contributed to the community's own process of leadership development. The stories also discuss the various roles participants in this collaboration played both in the academic arena and in the community, and how they experienced gender, race, nationality, and social status.
