| claim-type | mechanism— “We propose a more general reflective-automatic model (RAM), which postulates that, in addition to cognitive change, interventions can also rely exclusively on contextual change as an alternative route to behaviour change.” | |
| method — evidence | — “In the following section, we review the most influential traditional models of behaviour change in order to demonstrate that such models rely on the reflective cognitive system to bring about behaviour change.” | |
| transfer | from behavioural economics: prospect theory and the incentive-response account of choice, taken from behavioural economics into the design of population-wide health behaviour-change interventions— “As such, behavioural economics has been mostly concerned, broadly, with how people respond to incentives – and the landmark model in this field, prospect theory (Kahneman & Tversky, 1979), describes how people actually make risky financial decisions.” | transfers[0] |
| mechanism | Contextual cues trigger already-existing automatic processes, which produce the action directly, so no belief or goal has to be changed for behaviour to change— “None of these methods require any change of cognitions, but instead represent aspects of the choice environment, which trigger already existing cognitive processes that, in turn, produce choice of actions beneficial for the individual.” | mechanisms[0] |
| mechanism | A prime automatically spreads activation to the behaviours, feelings and thoughts historically associated with it, which is why an apparently irrelevant cue can steer action— “The cue or prime automatically activates behaviours, feelings and thoughts that have a history of association” | mechanisms[1] |
| mechanism | People infer their own attitudes from watching their own (context-driven) behaviour, so an externally cued behaviour change feeds back into cognitive change— “This aspect of RAM incorporates Bem's (1967) self-perception theory, which proposed exactly this – we form our attitudes, opinions, and other internal states by observing our behaviour and concluding what attitudes must have caused them.” | mechanisms[2] |
| builds-on | Bem's (1967) self-perception theory— “This aspect of RAM incorporates Bem's (1967) self-perception theory, which proposed exactly this – we form our attitudes, opinions, and other internal states by observing our behaviour and concluding what attitudes must have caused them.” | claim_relations[0] |
| extends | Thaler and Sunstein's (2008) six principles of choice architecture ('nudges')— “In summary, the set of behaviour change principles included in RAM represent a more general and systematised framework than the six nudges offered by Thaler and Sunstein (2008), which also explains ‗why‘ and ‗how‘ these nudges work.” | claim_relations[1] |
| extends | the reflective-impulsive model (Strack & Deutsch, 2004)— “Also, the reflective-impulsive model does not postulate social norms and salience as determinants of behaviour (although topdown effects of attention directed by the impulsive system are discussed).” | claim_relations[2] |
| builds-on | Webb and Sheeran's (2006) meta-analytic review of intention-change experiments— “However, Webb and Sheeran (2006) provide evidence that whenever considered, environmental (contextual) change can produce effects comparable to standard interventions, which is based on a systematic review of experimental studies of the impact of changing peoples‘ intentions on subsequent behaviour change.” | claim_relations[3] |
| sense | priming, in behavioural public policy - a TWO-SIDED operation on attention, and the second side is written into the definition: it enhances processing of some aspects of the choice environment AND SUPPRESSES processing of others. Luoma-aho2019 has the same shape (`leaves out others`); this one narrows the suppression to the conceptually unrelated— “Priming activates (cues) knowledge in memory in order to enhance processing of aspects of the choice environment (and to suppress processing of other conceptually unrelated aspects)” | senses[0] |
| sense | priming as ONE OF FOUR - the P of SNAP, placed beside salience, norms and affect rather than defined against framing or anchoring. In this corpus the same word has been a cognitive phenomenon, a media effect, an economic treatment, a property of a mollusc's ganglion, and here a quarter of a policy instrument— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming” | senses[1] |
| sense | the automatic route, as a POLICY claim rather than a psychological one - interventions can rely EXCLUSIVELY on contextual change, which is what detaches behaviour change from belief change and makes the model an instrument rather than a description— “We propose a more general reflective-automatic model (RAM), which postulates that, in addition to cognitive change, interventions can also rely exclusively on contextual change as an alternative route to behaviour change” | senses[2] |
| sense | habit, as this paper borrows it - a definition taken whole from Wood, Tam and Witt rather than built: behavioural dispositions to repeat well-practiced actions given recurring circumstances. The recurrence is in the CIRCUMSTANCES, which is what lets a context-changing intervention reach it— “Habits have been defined as ‗behavioural dispositions to repeat well-practiced actions given recurring circumstances” | senses[3] |
| differs in | reflective system —distinct-from→ automatic system — WHICH KIND OF CHANGE EACH RESPONDS TO - the reflective system to changed cognitions, the automatic system to a changed context— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions and the automatic system responds to changing the context”— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions” | concept_edges[0] |
| note | reflective system —distinct-from→ automatic system — The model's whole architecture in one sentence, and the split is defined by the INTERVENTION each route answers to rather than by properties of the processing.— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions and the automatic system responds to changing the context” | concept_edges[0] |
| weight | reflective system —distinct-from→ automatic system — 0.95— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions and the automatic system responds to changing the context” | concept_edges[0] |
| note | priming —part-of→ SNAP — Placement rather than definition, and it is the paper's actual contribution: priming is put beside salience, norms and affect as a policy lever, not defined against framing or anchoring as in every other record tagged tonight.— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming” | concept_edges[1] |
| weight | priming —part-of→ SNAP — 0.95— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming” | concept_edges[1] |
| note | salience —part-of→ SNAP — The other three principles are nodes on this record for the same reason - the acronym is the unit of the claim, so an edge to it is what makes the membership queryable.— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming” | concept_edges[2] |
| weight | salience —part-of→ SNAP — 0.95— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming” | concept_edges[2] |
| audit | priming —part-of→ automatic system — Audit 2026-09-28: DOUBTFUL - read against its full span and kept, but SNAP responses work 'mostly on the automatic system'; part-of is loose.— “We also propose that salience, norms, affect and priming are SNAP responses cued by the context and working mostly on the automatic system” | concept_edges[3] |
| note | priming —part-of→ automatic system — Hedged - 'mostly' - and weighted for it. The hedge matters: the paper does not claim the SNAP processes are inaccessible to reflection, only that they do not require it.— “We also propose that salience, norms, affect and priming are SNAP responses cued by the context and working mostly on the automatic system” | concept_edges[3] |
| weight | priming —part-of→ automatic system — 0.9— “We also propose that salience, norms, affect and priming are SNAP responses cued by the context and working mostly on the automatic system” | concept_edges[3] |
| replication | untested | |
| limitation | The paper flags three unresolved conceptual and empirical issues with its own framework.— “We recognise, of course, that there are still some unresolved conceptual and empirical issues that require further research and we highlight three by way of conclusion.” | limitations[0] |
| limitation | RAM explains how people behave far better than it explains how to get them to change; the process-of-change side is undeveloped.— “The first we develop in detail, but the second is less developed yet.” | limitations[1] |
| limitation | Whether SNAP-based interventions produce lasting rather than short-lived change is unsettled.— “The third issue relates to the sustainability of SNAP-based interventions – i.e. whether behaviour change is only short-term or long-lived.” | limitations[2] |
| limitation | The behavioural-economics evidence base transfers imperfectly to population behaviour change: few long-term studies, randomised trials or process studies.— “In this respect, there are some limitations of applying results of behavioural economics to population behaviour change (e.g., in health) as there are few long terms studies and randomised controlled trials, and few process studies.” | limitations[3] |
finding · quantity · variable · definition · key-term — grounded in the full text| finding | The paper's model claims behaviour change runs through two routes on two different processing systems: the reflective system changes cognitions, while the automatic system responds to changes in the context.— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions and the automatic system responds to changing the context.” | content_tags.findings[0] |
| finding | The authors name four context-cued processes that work through the automatic system: salience, norms, affect and priming.— “We also identify four processes: salience, norms, affect, and priming (SNAP), which can bring about behaviour change by relying mainly on the automatic system.” | content_tags.findings[1] |
| finding | Across the traditional behaviour-change literature the authors find that every model targets one or more of just three psychological variables: beliefs, goals and habits.— “they attempt to change one or more of three psychological variables: beliefs, goals, and habits.” | content_tags.findings[2] |
| finding | Reviewing cost-effectiveness evidence, the authors conclude that environmental interventions can be substantially more cost-effective than traditional individual behavioural interventions.— “The really interesting result is that environmental interventions have the potential to be substantially more cost-effective than more tradition behavioural interventions” | content_tags.findings[3] |
| finding | Habits are argued to act more as constraints on behaviour change than as mechanisms for it.— “In this respect habits more act as constraints on behaviour change, not as mechanisms for behaviour change.” | content_tags.findings[4] |
| finding | Salience and norm interventions can change behaviour without any accompanying change in beliefs or attitudes.— “such cognitive change is not required for salience and norms for have an effect on behaviour.” | content_tags.findings[5] |
| finding | The situational (SNAP) methods assume that changing a person's environment will produce sustained behaviour change without any change in cognitions.— “In contrast, the ‗situational‘ methods (SNAP) are based on the assumption that changing the person‘s environment will result in sustained behaviour change without necessitating any change in cognitions.” | content_tags.findings[6] |
| finding | The authors claim RAM is the first consistent application of the dual-process paradigm specifically to behaviour-change interventions.— “first consistent application of the dual-process paradigm specifically to behaviour change interventions.” | content_tags.findings[7] |
| finding | RAM contains a feedback loop from behaviour back to the underlying cognitions, which traditional methods do not explicitly discuss.— “contains a feedback loop from behaviour back to the underlying cognitions, which is not explicitly discussed in traditional methods” | content_tags.findings[8] |
| quantity | 3% ... 30% — share of shoppers who bought jam when 24 flavours were displayed versus when only 6 were displayed, cited as evidence of choice overload— “Iyengar and Lepper (2000) showed that 3% of consumers bought jam when there were 24 flavours on display whereas 30% did when there were 6 flavours on display (even though 60% sampled the jams in the former and 40% in the latter condition).” [ATTRIBUTED TO A CITED AUTHOR, NOT THIS PAPER] the paper’s own words: “Iyengar and Lepper (2000) showed” | content_tags.quantities[0] |
| quantity | 26% — increase in hotel guests' towel reuse produced by a descriptive-norm sign relative to a standard environmental-protection sign— “The descriptive-norms message made customers 26% more likely to recycle their towels than those who saw the basic environmental-protection message.” | content_tags.quantities[1] |
| quantity | 28% — drop in teen pregnancy in Kenya after HIV risk information was made salient by partner age group— “Providing information on the relative risk of HIV infection by partner's age group led to a 28% decrease in teen pregnancy (and 61% decrease in the incidence of pregnancies with older, riskier partners).” | content_tags.quantities[2] |
| quantity | 13% ... 41% — increase in soap use after the toilet and in reported soap use before eating produced by a disgust-based (affect) campaign in Ghana— “which resulted in a 13% increase in the use of soap after the toilet and 41% increase in reported soap use before eating.” | content_tags.quantities[3] |
| quantity | 22% — reduction in calories per serving expected from replacing a 12-inch plate with a 10-inch plate— “if the 12 inch plates are reduced to 10 inch plates, this would result in 22% reduction of calories per serving” | content_tags.quantities[4] |
| quantity | .18 — intention-behaviour correlation once only experimental studies are meta-analysed, about 3% of variance in behaviour— “However, when Webb and Sheeran (2006) based their meta-analysis only on (47) experimental (i.e., causal, not correlational) studies, the estimated intention-behaviour correlation dropped to .18 (i.e., accounting for ~3% of the variance).” | content_tags.quantities[5] |

| definition | SNAP— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming.” | content_tags.definitions[1] |
| definition | salience— “The salience of a stimulus – be it an object, a person, etc. – is its state or quality of standing out relative to neighbouring stimuli.” | content_tags.definitions[2] |
| definition | social and cultural norms— “Social and cultural norms are the behavioural expectations, or rules, within a society (or group), which are used by the latter to control for appropriate and inappropriate values, beliefs, attitudes and behaviours (Bicchieri, 2006).” | content_tags.definitions[3] |
| definition | priming— “Priming activates (cues) knowledge in memory in order to enhance processing of aspects of the choice environment (and to suppress processing of other conceptually unrelated aspects).” | content_tags.definitions[4] |
| definition | commitment— “Commitment is making a choice of a future state of the world that requires some action and imposes some cost otherwise.” | content_tags.definitions[5] |
| definition | defaults— “Defaults are options that are assumed as preselected if the individual does not make an active choice of another available alternative.” | content_tags.definitions[6] |
| concept | priming — not defined in this paper's own words; defined here by BOTH halves of what it does to attention: it cues knowledge that enhances processing of some aspects of the choice environment and SUPPRESSES processing of others - and the suppression is restricted to the conceptually unrelated— “Priming activates (cues) knowledge in memory in order to enhance processing of aspects of the choice environment (and to suppress processing of other conceptually unrelated aspects)” | concepts[0] |
| concept | salience — not defined in this paper's own words; the S of SNAP: the first of four context-cued processes the paper puts on the automatic side, alongside norms, affect and priming— “The framework is called SNAP, which is an acronym for the following four principles: Salience, Norms, Affect and Priming” | concepts[1] |
| concept | SNAP — not defined in this paper's own words; the acronym that IS the contribution: four named processes that a policy maker can act on without changing anyone's beliefs, because they work through the automatic system— “We also identify four processes: salience, norms, affect, and priming (SNAP), which can bring about behaviour change by relying mainly on the automatic system” | concepts[2] |
| concept | reflective system — not defined in this paper's own words; the deliberative route, and the one every existing theory the paper reviews relies on: it is what changing cognitions acts upon— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions and the automatic system responds to changing the context” | concepts[3] |
| concept | automatic system — not defined in this paper's own words; the other route, and the paper's actual proposal - that an intervention can work through it EXCLUSIVELY, by changing the context and leaving cognitions alone— “RAM is a dual-process model which assumes that these two routes rely predominantly on different information processing systems – the reflective system is in charge of changing cognitions and the automatic system responds to changing the context” | concepts[4] |
| concept | behaviour change — not defined in this paper's own words; the outcome the whole model is built to produce, and the paper's move is to detach it from belief change - which is what makes the automatic route a policy instrument— “We also identify four processes: salience, norms, affect, and priming (SNAP), which can bring about behaviour change by relying mainly on the automatic system” | concepts[5] |
| concept | context — not defined in this paper's own words; what the automatic route manipulates instead of cognitions; the paper's title makes the substitution its thesis— “We also propose that salience, norms, affect and priming are SNAP responses cued by the context and working mostly on the automatic system” | concepts[6] |
When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
