A plant can survive the city without being acknowledged as belonging to it. This asymmetry is not exhausted by the difference between biological presence and cultural preference: it runs through the very instruments that make urban nature actionable. The garden and the vacant lot, the curated arboretum and the roadside colony, the officially selected tree and the species that takes root without permission, all expose a friction between life as an ongoing process and the institutional forms through which life is named, ordered, maintained or eliminated. In the research of Catarina Patoilo Teixeira and collaborators, ecological novelty is not a romantic celebration of wilderness inside the metropolis. It identifies biological assemblages emerging under anthropogenic pressure, including climates and disturbances to which conventional planting prescriptions may be poorly fitted. Novelty therefore cannot be read off appearance alone. A spontaneous patch can provide ecological functions that its unplanned status renders culturally suspect; a formally planted scheme can bear an exemplary environmental label without delivering the ecological diversity that label suggests. This tension is particularly precise in the survey of Portuguese landscape professionals. By decomposing Novel Urban Ecosystems into the axes native/non-native and cultivated/spontaneous, Teixeira, Fernandes, Ryan and Ahern reveal that the act of classification has practical consequences for acceptance. The remarkable implication is not that experts can be persuaded to like plants, but that the conceptual frame through which an organism is presented participates in the judgement made about it. When the description changes, some evaluations shift. Yet the study does not eliminate the distinction between an expressed judgement and an experienced place: its questionnaire records professional responses, not lived encounters along routes, and the authors identify the restricted professional sample as a limitation. The distance is productive. It indicates a form of evidence still required between ecological inventory and social judgement: situated encounter, in which a person may move from heat into shade, from a visibly maintained path into spontaneous growth, from a refuge to an obstructed sightline, and register different forms of comfort or uncertainty without first classifying the vegetation botanically. The adaptive planting framework takes a second step by refusing to make the design of nature into a single moment of authorship. Climate assessment, trait-based species knowledge and iterative management form a sequence in which a site must remain capable of teaching its designers. The categories remove, monitor, keep and add appear practical, but they disclose an ethics of non-finality: ecological value can alter as environmental conditions change, and the grounds for intervention can be reconsidered. This is a discipline of provisional decisions, not an exemption from ecological risk. The accompanying plant-traits database clarifies how such decisions are made legible. Two hundred and eighty-seven species become a structured field of recorded capacities, tolerances, forms and potential hazards; the data's apparent stability conceals both the work of sampling and the inevitable selectivity of its variables. A crown can be described through density and dimensions, but its perceived hospitality is not reducible to those attributes. A flowering season may indicate potential resources for insects, but neither the actual activity of pollinators nor the aesthetic meaning of a meadow follows automatically from a spreadsheet entry. Fernandes and colleagues' study of seed mixtures sharpens this distinction between designation and performance: a market in ecological solutions depends on descriptors whose credibility must be checked against composition and explicit criteria. Only a minority of the mixtures examined meet the paper's selected pollinator-friendly criteria, a result that does not warrant universal claims about all mixes but does expose the fragility of self-declared environmental virtue. At the other end of the spectrum, the arboretum represents nature made deliberately legible: accession, arrangement, circulation and visitor services operate together, transforming living collections into an architectural and educational apparatus. Its spatial order does not merely accommodate botanical knowledge. It edits the sequence in which knowledge can be encountered. The cultivated and the spontaneous are thus not two opposing kinds of vegetation. They are two unstable political and epistemic positions within an urban system that decides how nature becomes evidence, experience and public legitimacy.
The difficulty for Socioplastics begins exactly where the conventional green map appears sufficient. A mapped polygon labelled park or an inventory point labelled tree can be correct in its own terms and still fail to explain what becomes possible for a particular walker at a particular hour. The botanical, administrative and experiential descriptions of the city do not occupy the same scale or temporal resolution. An ecological dataset may follow species and traits; a planning layer may locate designated land uses; a visitor may remember the cool edge of a wall, an inaccessible gate, flowering weeds beside a neglected pavement or the unexpected attraction of a less regulated landscape. None of these observations invalidates the others, but none should be allowed to stand in silently for them. This is the opening for an observational grammar in which living vegetation, spatial affordance, interpretation and movement are recorded as distinct yet potentially comparable layers. Teixeira's research offers both resources and warnings for such a grammar. The plant-traits database demonstrates the utility of clearly defined fields, source provenance and reusable classifications. Its sampling from ecologically novel sites demonstrates that selection is never innocent: a database is shaped from the start by a decision about which places will count. The arboretum study demonstrates how standardised georeferencing and vectorisation can make unlike landscapes comparable, while its institutional diversity reminds us that the common map does not dissolve local governance, histories or modes of access. The professional-attitudes survey warns against confusing familiarity with ecological categories and public acceptance; indeed, a visitor's relation to spontaneous vegetation may be articulated without any prior awareness of ecological novelty as a scientific idea. For fieldwork, the consequence is to avoid asking walkers to become amateur botanists. Expert ecological assessment can remain an independent layer, linked to but not substituted for statements about shade, visibility, scent, vegetation density, perceived care, fear, pleasure or fatigue. The record of a walk would then be a sequence of situated differences, not a global vote on whether greenery is desirable. The same tree may provide shade and obstruct a sightline; spontaneous vegetation may carry habitat value and still be read as neglect; a planted mix may be rich in signage but poor in sustained floral resources. These conditions should not be flattened into an automatic composite score. They can instead be described through documented relations and unresolved disagreements: the experience is specific, the ecological evidence independent, and the comparative claim limited to variables that can legitimately travel between settings. Seasonal repetition becomes essential because vegetative performance and human responses have different calendars. An arboretum's circulation network may remain recognisably stable while its canopy, flowering, access conditions and public uses change; a roadside meadow may be briefly spectacular before being cut, and a vacant site may move between refuge, habitat, enclosure and redevelopment without altering its position on the map. Field evidence therefore needs time-stamped observations, an explicit account of what was actually seen, a distinction between measured properties and attributed meanings, and a record of the conditions under which comparison was made. Metadata are not clerical additions here. They are the means by which a claim can remain answerable to the circumstances of its production. An archival photograph of an overgrown lot, a botanical inventory and an interview about its perceived safety may all be durable records; their productive relation depends on keeping their objects, periods and methods visibly distinct. The same principle applies to governance. A city's vegetation does not speak in a single register. Municipal maintenance, biodiversity conservation, residents' claims, professional design judgements and the legal treatment of invasive risk can authorise contradictory interventions in the same space. The question is not how to abolish conflict through a perfect ecological indicator, but how to preserve enough of its structure for decisions to remain revisable and publicly intelligible. An urban research instrument earns its authority by making the limits of its claims inspectable. Teixeira's constellation makes possible an account of landscape not as a decorative surface covering urban infrastructure, but as a changing infrastructure of living capacities whose meanings are co-produced by classification, administration, ecological processes and situated encounter. Within Socioplastics, this tension can be retained without inventing a new operator: it demands a comparative record in which the spontaneous is neither romanticised nor erased by the cultivated.

The Old Moat study is a precise demonstration that entry into a public-looking place may be socially inhibited without a locked gate. Fifteen older people in Greater Manchester explored small green spaces through walk-along interviews and photo elicitation. Some spaces were perceived as belonging to other people or as poorly maintained, and larger parks remained more attractive destinations. The sample was small and specific, but the research produced a category that an inventory of green cover cannot generate: perceived entitlement to use. A patch of green can be territorially present, publicly designated and functionally unavailable to someone who reads its social signals as exclusion. Combining photographs with situated speech exposes how meanings attach to particular sites rather than to an abstract provision category. Health psychology, urban sociology and planning thereby become connected through a question of implicit ownership. A route can approach a place without the walker regarding it as theirs to enter.

Adichie, C.N. (2009) ‘The Danger of a Single Story’, TEDGlobal, Oxford [transcript].
Adichie turns narrative asymmetry into a theory of identity and power. The “single story” does not operate simply by disseminating false information; it reduces complex persons and places to one repeatedly available account until that account becomes the dominant condition of recognition. Her autobiographical examples show that representation works through repetition, unequal access to narration and the authority to decide which stories become general knowledge. Methodologically, the talk uses situated narrative rather than abstract typology, allowing the argument to demonstrate its own claim: multiplicity is restored by adding standpoints, histories and contradictions that a dominant account has excluded. The bridge to social psychology is direct because categorisation and stereotype are shown as narrative processes, while the bridge to postcolonial theory lies in the unequal distribution of representational power. Identity emerges as vulnerable to narrative compression but not reducible to it. Counter-storytelling becomes an epistemic and political practice through which categories can be reopened rather than merely replaced by new fixed images.

Vázquez and Muñoz displace memory from the model of individual storage toward an account of remembering as social action. Their key proposition is that the past is not simply retained and retrieved; it is reconstructed through language, interaction, artefacts, institutions and present concerns. The distinction between “social” and “collective” memory becomes analytically productive because it forces the question of how a collectivity can remember without being reduced to an aggregate of individual brains. Methodologically, the chapter moves from conventional psychological treatments of memory toward constructionist and discursive approaches, emphasising shared meanings and the practical consequences of versions of the past. Remembering and forgetting are therefore not neutral cognitive operations but ways of organising responsibility, continuity and possible action. The chapter bridges social psychology with historiography, memory studies and public culture. Its strongest implication is that identity depends on temporal infrastructures: groups and persons become intelligible by sustaining narratives of continuity whose form is negotiated in the present.

Gómez Mendoza, J. (2004) ‘La mirada de la geografía. Paisajes en transformación: el caso de los paisajes forestales’.
Gómez Mendoza defines the geographical gaze as a disciplined capacity to move between observation, synthesis, scale and historical transformation. Landscape is not reduced to image or aesthetic object: it is a quality of territory whose intelligibility depends on knowing how natural and cultural relations have been assembled through time. The essay gives particular force to fieldwork and direct observation, recovering Manuel de Terán’s maxim of a geography of ‘andar y ver’ while linking it to Humboldtian visual thinking and narrative ordering. Its most consequential claim concerns scale: changing scale is not equivalent to enlarging or reducing the same object, because different phenomena become visible, significant or unintelligible at different spatial levels. Medium scales acquire special importance as territorial and landscape observatories. The wider bridge is to epistemology: geographical knowledge is produced through calibrated acts of seeing, moving, narrating and rescaling, each of which transforms what can legitimately count as the object under study.

Brandtner and Wegmann situate FoMO within the cognitive-affective dynamics of desire rather than treating it as inherently pathological. Drawing on the Elaborated Intrusion Theory of Desire, they test how desire thinking, FoMO and craving interact in problematic social networking-site use among 193 participants. Their most important conceptual result is negative in a productive sense: neither desire thinking nor FoMO becomes dysfunctional by definition; problematicity emerges through their interaction with craving and patterns of use. This reframes FoMO as a contingent process rather than a fixed deficit. Methodologically, the study uses serial mediation to specify the sequence through which verbally elaborated desire can contribute to FoMO and, under certain conditions, problematic use. The work bridges cognitive psychology, behavioural addiction research and media studies by locating platform use within loops of anticipation, imagined participation and recurrent checking. It thereby complicates moralising accounts of digital behaviour and provides a mechanism-sensitive model of how affective anticipation becomes technologically organised.

Mesquita, De Leersnyder and Boiger replace the image of culture as an external modifier of universal emotions with a processual account in which emotions are made through recurrent social relations and culturally patterned situations. Their central contribution is the concept of emotional fit: affective experience can align more or less closely with culturally prevalent patterns, and that alignment changes through participation, migration and social contact. The chapter draws on cross-cultural comparisons, diary studies, survey data and acculturation research, but its methodological argument is more radical than simple comparison. Context should not be controlled away as noise because context partly constitutes the phenomenon. Emotional episodes are therefore relational accomplishments embedded in moral orders, interactional expectations and culturally valued forms of action. This position bridges cultural psychology with ecological and situated approaches to cognition. It also challenges decontextualised experimental designs by proposing that emotional processes should be studied where they are socially produced: in practices, relationships and environments rather than as isolated responses.

Actitudes y discurso reconstructs the attitude concept from an apparently internal psychological property into a historically variable and socially consequential practice of evaluation. The text’s key move is to shift attention from what people supposedly “have in their heads” to what evaluations accomplish in situated language. Discursive approaches treat attitudes as positions enacted through talk, rather than as stable predispositions awaiting measurement. This theoretical reorientation also foregrounds ideology, power and institutional effects: discourse is analysed not only for what it represents but for what it authorises, normalises or excludes. Methodologically, the text links conceptual history to discourse analysis, showing how competing definitions of attitude imply different models of the person, knowledge and social reality. Its wider significance lies in connecting social psychology with critical discourse studies and governmentality: evaluative language becomes a mechanism through which subjects and social objects are stabilised. The work therefore makes discursivity operational without reducing discourse to rhetoric alone.

Falzon and Conrad examine nature-based learning through the material specificity of the environments in which it occurs. Their review is especially valuable because it refuses to treat “nature” as a generic positive variable: the central question is how particular spatial characteristics enable or constrain learning, wellbeing and nature connectedness. The conceptual operation is relational. Drawing on ecological psychology and affordance theory, learning emerges from transactions between people and environments rather than from exposure to scenery alone. This makes design pedagogically consequential: access, complexity, multisensoriality, vegetation, spatial limitation and the possibilities for action offered by a site become part of the learning apparatus. The review also highlights significant evidential gaps, especially in dense urban contexts and across diverse cultural and geographical settings. Its bridge to environmental psychology is precise: educational outcomes depend on person–environment relations that are simultaneously functional, affective and spatial. Nature-based learning therefore becomes a question of how environments invite attention, action, attachment and interpretation.

Taghizadeh Kerman and colleagues treat feedback as a structured learning process rather than a correction appended to completed work. Their systematic synthesis shows that online feedback operates through an interaction among learner characteristics, learning environments, activity design and desired outcomes. Its important methodological contribution is to make feedback architecture explicit: who responds, through which platform, according to what criteria, at what moment and with what opportunity for revision all condition the educational effect. Online environments add flexibility and scalability, but the review resists technological determinism by identifying trust, feedback literacy, disciplinary knowledge and task complexity as decisive variables. Feedback can support writing, professional judgement, argumentation, self-regulation and communication, yet poorly designed exchanges can remain superficial or unusable. The work therefore bridges assessment theory and digital learning by showing that response is itself a pedagogical medium. Learning intensifies when a participant’s specific production becomes the object of attention, comparison and revision rather than disappearing into standardized completion metrics.

Jelewska proposes postdigital collective memory as a form of remembrance co-produced by humans, nonhumans, environments and technological media. The article develops this idea through field practices and design workshops at Lake Rusałka in Poznań, a landscape whose wartime history had been materially transformed and publicly suppressed. Its central device, the Sensitive Data Lake, is not conceived as a neutral database but as an experimental environment in which archives, sensors, ecological processes, narratives and artificial intelligence can generate friction around the past. Critical Media Design supplies the methodological operation: remembrance is produced through situated making rather than deposited after the fact into a stable archive. The paper thereby challenges “total design”, understood as the attempt to render environments fully ordered, legible and controllable. Memory instead becomes plural, spectral and transitional. The wider bridge joins posthumanism, media archaeology, transition design and critical infrastructure studies, establishing digital memory as an environmental relation whose politics depends on how heterogeneous agencies are allowed to enter the record.
