Standard protocols for plant health scientific assessments.

In accordance with the EFSA Strategy 2027 outlining the need for fit-for-purpose protocols for EFSA generic scientific assessments, the EFSA Panel on Plant Health (PLH Panel) developed standard protocols to harmonise the problem formulation process and outputs for mandates addressing recurrent scientific questions. Three types of recurring EFSA plant health mandates require generic scientific assessments: (i) pest categorisation; (ii) commodity risk assessment for the purpose of derogation to provisions of the EU plant health law and (iii) quantitative pest risk assessment. The three standard protocols are tailored to the appropriate level of detail and build on the existing guidance documents laying out the methods for conducting risk assessment in the plant health domain. To develop a standard protocol for pest categorisation, the PLH Panel adapted the latest version of the standard template reporting the evidence needs and the assessment questions to conclude whether a pest fulfils the criteria for being considered a potential quarantine pest for the EU. To develop a standard protocol for commodity risk assessment, the PLH Panel adapted the procedure and standard templates used for commodity risk assessment of high risk plants. To develop a standard protocol for quantitative pest risk assessments (qPRA), the Panel reviewed the existing guidance document on qPRA and the qPRAs published by the PLH Panel. The hierarchy of assessment questions and sub-questions used were identified and extracted. Based on this, a hierarchically organised IT-tool was formulated as protocol for the planning and documentation of future qPRAs.

Epidemiology of Field of Vision Disorders (eFOVID) study, Western Australia, 1988-2022. Report 1: Data collection and aggregation protocol.

BACKGROUND: Computerised static visual field testing using dedicated machines such as the Humphrey Field Analyzer (HFA) can assess and track changes in visual field sensitivity. The use of retrospective visual field databases is a novel undertaking, with no studies published utilising large scale population-level data. This study phase developed a method to extract HFA data into a large standardised population-based database including point sensitivity data with additional derived variables. METHODS: Retrospective, longitudinal, population study of visual field data from people who attended an ophthalmology service and had a HFA field test, in Western Australia, between 1988 and 2022. Raw test data included patient demographic fields, sensitivity readings and test parameters. Calculated fields included reliability scores, and a novel combined reliability score. RESULTS: There were 606 230 tests for 92 215 study individuals, from 22 ophthalmology practices in metropolitan Perth and three public hospital eye clinics, representing around 85% of the field tests performed by ophthalmologists each year. Raw sensitivity values were available for all tests, and additional descriptors were available for most tests (97.5%-100% of tests) with the exception of data variables retired by the manufacturer. CONCLUSIONS: Visual field data from 606 230 tests were collated into a single dataset, which is highly representative over a long period of time, for a defined population. This dataset has been linked to other administrative datasets to allow for epidemiological investigation of field of vision disorders.

On discretising continuous data for subgroup analysis in baseball pitching and alternative analytical methodologies.

There is a plethora of research attempting to contrast high- and low-velocity pitchers to identify traits to target for increasing velocity. However, pitch velocity exists on a continuum. Therefore, our purpose is to display the analytical discrepancies between creating velocity subgroups and leaving velocity as a continuous variable by examining the influence of ball velocity on elbow valgus torque. Motion capture data for 1315 actively competing pitchers were retrospectively extracted from a private database. We compared three analytic methods: (1) linear regression of valgus torque on ball velocity, (2) t-test between low- and high-velocity groups formed by a median split, and (3) t-test between very low- and very high-velocity groups formed by upper and lower velocity quartiles. Linear regression indicates ball velocity influenced valgus torque (p < 0.001, R2 = 0.280). Median splitting reduced the predictability of ball velocity on valgus torque (p < 0.001, R2 = 0.180). Conversely, extreme group splitting artificially inflated the effect size (p < 0.001, R2 = 0.347). We recommend sports biomechanics researchers not discretise a continuous variable to form subgroups for analysis because (1) it distorts the relationship between the variables of interest and (2) a regression equation can be used to estimate the dependent variable at any value of the independent variable, not just the group means.

Age-appropriate elder care recipients? Care manager's categorisation practices in intraprofessional case conferences.

Age categories are related to perceptions and norms concerning appropriate behaviour, appearances, expectations, and so forth. In Sweden, municipal home care and residential care are commonly referred to as "elder care", primarily catering to individuals in their 80s or 90s. However, there is no set age limit reserving these services for an older age group. In intra-professional case conferences, care managers convene with colleagues to discuss care needs and eligibility for elder care services. Despite their significance, these conferences have received limited scholarly attention. The aim of this study was to analyse how care managers categorise persons based on age in intra-professional case conferences when discussing care needs and appropriate support to meet these needs. The study utilised data from 39 audio-recorded case conferences involving the discussion of 137 different cases, which were analysed using discourse analysis. Our findings showed that chronological age was frequently made relevant and applied in discussions about the appropriateness of usual elder care services. Four themes emerged, representing how the care managers implicitly and explicitly categorised clients of different chronological ages as typical/normal or atypical/deviant in these discussions: the "too young", the "not-so-old", the "old", and the "extraordinarily old". The findings contribute to research on ageing by demonstrating that, in an elder care context, being categorised as atypical/deviant (in terms of being younger) may be more beneficial than being seen as a normal or older elder care recipient. This underscores the importance of further research on the impact of informal age categorisations of clients on actual decisions about welfare services.

Claiming and attributing (dis)taste: Issues of sharing a meal as a competent member.

Eating together is a primordial social activity with robust normative expectations. This study examines a series of instances where appreciative elements about the food during a shared meal are treated as noticeably absent and where some of the participants are attributed to exhibit a negative stance towards the food, which furthermore is used as a resource for engaging in membership categorization. Situated within the cognate approaches of ethnomethodology and conversation analysis, this study draws on video recordings of an integrated language and cooking workshop organized for immigrants in the French speaking part of Switzerland. The participants include a French teacher, two chefs and five immigrant women with various native languages. The detailed sequential, multimodal analysis details and explains how the participants treat gustatory features of eating as publicly available and accountable, and how the absence of evaluative elements contribute to the situated achievement of a plural "you" as a group that does not like "this" food. Ascribing (dis)taste for food on behalf of others, occasions accounts for just how to eat, showing the strong normative features that make up to the recognizability of sharing a meal as a competent member - including how sensorial experiences are evaluated and expressed. In this way, this study contributes to our understanding of the (non)ordinary features of eating together as a situated, embodied achievement and social institution that is built in and through interaction.

A drift diffusion model analysis of age-related impact on multisensory decision-making processes.

Older adults (OAs) are typically slower and/or less accurate in forming perceptual choices relative to younger adults. Despite perceptual deficits, OAs gain from integrating information across senses, yielding multisensory benefits. However, the cognitive processes underlying these seemingly discrepant ageing effects remain unclear. To address this knowledge gap, 212 participants (18-90 years old) performed an online object categorisation paradigm, whereby age-related differences in Reaction Times (RTs) and choice accuracy between audiovisual (AV), visual (V), and auditory (A) conditions could be assessed. Whereas OAs were slower and less accurate across sensory conditions, they exhibited greater RT decreases between AV and V conditions, showing a larger multisensory benefit towards decisional speed. Hierarchical Drift Diffusion Modelling (HDDM) was fitted to participants' behaviour to probe age-related impacts on the latent multisensory decision formation processes. For OAs, HDDM demonstrated slower evidence accumulation rates across sensory conditions coupled with increased response caution for AV trials of higher difficulty. Notably, for trials of lower difficulty we found multisensory benefits in evidence accumulation that increased with age, but not for trials of higher difficulty, in which increased response caution was instead evident. Together, our findings reconcile age-related impacts on multisensory decision-making, indicating greater multisensory evidence accumulation benefits with age underlying enhanced decisional speed.

Modelling the impact of single vs. dual presentation on visual discrimination across resolutions.

Visual categorisation relies on our ability to extract useful diagnostic information from complex stimuli. To do this, we can utilise both the "high-level" and "low-level" information in a stimulus; however, the extent to which changes in these properties impact the decision-making process is less clear. We manipulated participants' access to high-level category features via gradated reductions to image resolution while exploring the impact of access to additional category features through a dual-stimulus presentation when compared with single stimulus presentation. Results showed that while increasing image resolution consistently resulted in better choice performance, no benefit was found for dual presentation over single presentation, despite responses for dual presentation being slower compared with single presentation. Applying the diffusion decision model revealed increases in drift rate as a function of resolution, but no change in drift rate for single versus dual presentation. The increase in response time for dual presentation was instead accounted for by an increase in response caution for dual presentations. These findings suggest that while increasing access to high-level features (via increased resolution) can improve participants' categorisation performance, increasing access to both high- and low-level features (via an additional stimulus) does not.

The benefits of item-method-directed forgetting.

The present experiments examined the encoding and retrieval conditions in an item-method-directed forget (IMDF) study that included a novel control condition. In the IMDF condition, half of the items were followed by a remember cue whereas the other half were followed by a forget cue. In a remember-both control condition, half of the items were followed by an item identifier called Set A; whereas the other half of the items were followed by a Set B identifier. At the test, items were recalled as a function of the instruction cue or the set identifier. Across two experiments, directed-forgetting effects and associated benefits were found. Further, results from both studies revealed a new way to demonstrate the benefit of IMDF - directed-forgetting participants made more correct source attributions compared to remember-both participants. These benefits were obtained using a within-subjects IMDF paradigm (Experiment 1) as well as a between-subjects IMDF paradigm (Experiment 2). These patterns of results are consistent with several current theories of item-method-directed forgetting.

The role of category valence in prototype preference.

People prefer prototypical stimuli over atypical stimuli. The dominant explanation for this prototype preference effect is that prototypical stimuli are processed more fluently. However, a more recent account proposes that prototypes are more strongly associated with their category's valence, leading to a reversed prototype preference effect for negative categories. One critical but untested assumption of this category-valence account is that no prototype preference should emerge for entirely neutral categories. We tested this prediction by conditioning categories of dot patterns positively, negatively, or neutrally. In line with previous findings on the category-valence account, prototype preference reversed for negatively conditioned categories. However, prototype preference was similarly strong for positive and neutral categories. These findings imply that prototype preferences do not only reflect a transfer of category valence to exemplars. Instead, the results suggest that prototype preference is a multi-process phenomenon arising from the activated category valence and a fluency-based process. We discuss further implications for theories on fluency and prototype preference.

A bias-free test of human temporal bisection: Evidence against bisection at the arithmetic mean.

The temporal bisection procedure has been used to assess theories of time perception. A problem with the procedure for measuring the perceived midpoint of two durations is that the spacing of probe durations affects the length of the bisection point. Linear spacing results in longer bisection points closer to the arithmetic mean of the durations than logarithmic spacing. In three experiments, the influence of probe duration distribution was avoided by presenting a single probe duration of either the arithmetic or geometric mean of the trained durations. It was found that the number of participants that categorised the arithmetic mean as long was significantly larger than those that categorised it as short. The number of participants that categorised the geometric mean as either short or long did not significantly differ. This was true for trained durations of 0.4 s vs. 1.6 s (Experiments 1-3), 0.2 s vs. 3.2 s (Experiment 2) and 0.4 s vs. 6.4 s (Experiment 3). In Experiment 4, the probe trial distribution effect was replicated with logarithmic and linearly distributed probe durations, demonstrating that bisection occurs close to the arithmetic mean with linearly spaced probe durations. The results provide evidence against bisection at the arithmetic mean when probe spacing bias is avoided and, instead, the results are consistent with logarithmic encoding of time, or a comparison rule based on relative rather than absolute differences.

Effects of perceptual redundancy, conceptual redundancy and self-relatedness on categorical responses.

A redundancy gain occurs when perceptually identical stimuli are presented together, resulting in quicker categorization of these paired stimuli than lone stimuli. Similar effects have been reported for paired stimuli within the same conceptual category, particularly if the category is self-related. We recruited 528 individuals across three related studies to investigate whether, during perceptual and conceptual redundancy, such self-bias effects on foreground stimuli are modulated by natural versus urban backgrounds. Here, we highlight our observations pertaining to perceptual and conceptual redundancy effects of the foreground stimuli. In our first experiment, response options were randomised per trial. Results showed reaction time gains for perceptually identical stimuli, but this advantage was not modulated by self/other categorization. However, slower reaction times were observed for conceptually-related stimulus pairs and were influenced by self/other categorization. The second experiment replicated the methods of earlier studies of redundancy and observed comparable results to Experiment 1: a perceptual redundancy gain unmodulated by self/other categorization, yet for conceptual redundancy, no gain/cost but effects of self/other categorization. In the third experiment, self/other categories were substituted with arbitrary A/B categories: Once more, there was a perceptual redundancy gain and no conceptual redundancy gain. Notably, A/B categorisation produced effects equivalent to self/other categorisation. Overall, these findings challenge previous research on the facilitated early processing of conceptually-related stimuli and suggest that self-relatedness may not exert a unique effect on stimulus processing beyond attentional and response preferences during categorization. Our study motivates further research to understand conceptual categorization and redundancy gain effects.

Acquisition of colour categories through learning: Differences between hue and lightness.

Colour categories are acquired through learning, but the nature of this process is not fully understood. Some category distinctions are defined by hue (e.g. red/purple) but other by lightness (red/pink). The aim of this study was to investigate if the acquisition of key information for making accurate cross-boundary discriminations poses different challenges for hue-defined as opposed to lightness-defined boundaries. To answer this question, hue- and lightness-learners were trained on a novel category boundary within the GREEN region of colour space. After training, hue- and lightness-learners as well as untrained controls performed delayed same-different discrimination for lightness and hue pairs. In addition to discrimination data, errors during learning and category-labelling strategies were examined. Errors during learning distributed non-uniformly and in accordance with the Bezold-Brücke effect, which accounts for darker colours at the green-blue boundary appearing greener and lighter colours appearing bluer. Only hue-learners showed discrimination improvements due to category boundary acquisition. Thus, acquisition is more efficient for hue-category compared to lightness-category boundaries. Almost all learners reported using category-labelling strategies, with hue-learners almost exclusively using 'green'/'blue' and lightness learners using a wider range of labels, most often 'light'/'dark'. Thus, labels play an important role in colour category learning and such labelling does not conform to everyday naming: here, the label 'blue' is used for exemplars that would normally be named 'green'. In conclusion, labelling serves the purpose of highlighting key information that differentiates exemplars across the category boundary, and basic colour terms may be particularly effective in facilitating such attentional guidance.

Analysis of the status and content of consultations with a Cancer Consultation and Support Centre during the COVID-19 pandemic.

PURPOSE: Cancer Consultation and Support Centres (CCSCs) in Japan have been established at designated cancer hospitals nationwide and these centres provide information and consultation support for cancer care. The purpose of this study is to analyse the status and content of consultations during the COVID-19 pandemic using consultation record data from the Cancer Consultation Support Centre (CCSC) database from January 2020 to March 2021. METHODS: First, we examined the number and percentage of cases involving and not involving COVID-19 and compared the items of the entry forms between the groups. The comparison between the two groups suggests that the traditional consultation items used before the COVID-19 pandemic did not adequately cover the consultation content during the COVID-19 pandemic. Therefore, we categorised the content of consultation records related to COVID-19. RESULTS: As a result, the content was consolidated into 16 categories, which were appropriately captured from five different aspects. CONCLUSION: Using the resulting categories, we were able to create a complementary consultation entry form that could be operational during the COVID epidemic and consult consultants for the support they needed. TRIAL REGISTRATION: Not applicable.

Cooperation and group similarity in children and young adults in the UK.

For cooperation to be beneficial, cooperators should be able to differentiate individuals who are willing to cooperate from free-riders. In the absence of kin or of familiar individuals, phenotypic similarity (e.g. in terms of language) can be used as a cue of how likely two or more individuals are to behave similarly (whether they will cooperate or free-ride). Thus, phenotypic similarity could affect cooperation. However, it is unclear whether humans respond to any type of phenotypic similarity or whether only salient phenotypic traits guide cooperation. We tested whether within-group, non-salient phenotypic similarity affects cooperation in 280, 3 to 10 year old children and in 76 young adults (mean 19.8 years old) in the UK. We experimentally manipulated the degree of phenotypic similarity in three computer-based experiments. We found no evidence of a preference for, or greater cooperation with, phenotypically similar individuals in children, even though children displayed ingroup preference. Conversely, young adults cooperated more with phenotypically similar than with phenotypically diverse individuals to themselves. Our results suggest that response to non-salient phenotypic similarity varies with age and that young adults may pay more attention to non-salient cues of diversity then children.

[The benefits of PSI when dealing with large numbers of victims]. / L'intérêt de disposer d'ISP lors de la prise en charge de nombreuses victimes.

The Many Victims plan describes aims to organize evacuations in a coherent manner, to preserve the human and material resources capacity of the fire and rescue service. The aim is to avoid postponing the disaster on the ground to the hospital and to guarantee the continuity of response to the current risk and an over-event. In this device, the firefighter nurse is an asset by his ability to take care of serious victims without the physical presence of a doctor, in a context of crisis.

Prior experience of variability influences generalisation of unspecified categories.

Category variability or diversity is an important factor influencing generalisation. However, expectations of category variability may not only depend on the variability of encountered category members, but may also be shaped by prior experiences with similar categories. In this study, we investigated whether we could influence category generalisation by inducing different category representations in an A/Non-A categorisation task: Participants either learned about a homogeneous category Non-A or a diverse category Non-A during a priming phase. To better understand the transfer process, we varied the nature of the learning phase from implicit transfer to explicit instructions that actively requested participants to use their prior experiences. We found that while with a homogeneous Non-A representation, generalisation of the A and Non-A categories was equal, the generalisation of category Non-A widened after a priming phase with a diverse representation. In a second experiment, we found that the widening of generalisation of category Non-A occurred when the exemplars in this category were themselves diverse (feature-diverse condition) but not when the category contained distinct exemplars (exemplar-diverse condition). These results suggests that categorisation is influenced by previous categorisation experiences possibly altering the representation of a category. Furthermore, the study gives a hint what kind of heterogeneity is needed to observe the commonly reported broader generalisation of diverse categories. The finding has implications not only to understand the influence of prior experiences on category learning, but any cognitive process that hinges on generalisation.
