Rapid communication: Perceptual strength is different from sensorimotor strength: Evidence from the centre–periphery asymmetry in masked priming

Near-threshold prime stimuli can facilitate or hinder responses to target stimuli, creating either a positive compatibility effect (PCE) or a negative compatibility effect (NCE). An asymmetry has been reported between primes presented in near periphery, which produced a PCE, and foveal primes, which produced an NCE under comparable conditions. This asymmetry has been attributed to the difference in retinal sensitivity, but it remains unclear whether this means that equating discrimination performance for primes in fovea and periphery, in order to account for differences in perceptual sensitivity, would make the priming effects the same. Wider work indicates that perceptual ability can dissociate from visuomotor effects, predicting that equating perceptual ability for fovea and periphery would not equate priming. We tested these opposite possibilities by matching discrimination performance for masked Gabor patches in fovea and near periphery (6°) and using these as primes in a masked priming paradigm expected to elicit NCEs. We found the asymmetry remained: NCE for fovea and PCE for periphery. We replicated this with both blocked and randomized procedures to check for attentional effects. We conclude that equating perceptual strength (discriminability) of stimuli does not equate their sensorimotor impact due to differences in the relative importance of different visual pathways and differing temporal dynamics in perceptual and sensorimotor processes.
The impact of working memory load on task execution and online plan adjustment during multitasking in a virtual environment

Three experiments investigated the impact of working memory load on online plan adjustment during a test of multitasking in young, nonexpert, adult participants. Multitasking was assessed using the Edinburgh Virtual Errands Test (EVET). Participants were asked to memorize either good or poor plans for performing multiple errands and were assessed both on task completion and on the extent to which they modified their plans during EVET performance. EVET was performed twice, with and without a secondary task loading a component of working memory. In Experiment 1, articulatory suppression was used to load the phonological loop. In Experiment 2, oral random generation was used to load executive functions. In Experiment 3, spatial working memory was loaded with an auditory spatial localization task. EVET performance for both good- and poor-planning groups was disrupted by random generation and sound localization, but not by articulatory suppression. Additionally, people given a poor plan were able to overcome this initial disadvantage by modifying their plans online. It was concluded that, in addition to executive functions, multiple errands performance draws heavily on spatial, but not verbal, working memory resources but can be successfully completed on the basis of modifying plans online, despite a secondary task load.
Lexical Stress, Frequency, and Stress Neighbourhood Effects in the Early Stages of Italian Reading Development

We examined the development of stress assignment in reading Italian aloud. We investigated frequency effects as a marker of the use of item-specific lexical knowledge in assigning stress together with stress dominance and stress neighbourhood (the number of words sharing both stress and ending) as markers of distributional information regarding properties of the lexicon extracted from spoken language. We tested second- and fourth-graders in a reading-aloud experiment including high- and low-frequency words and nonwords. Results show that despite the regularity of orthography–phonology mappings in Italian and the predominant use of phonological recoding procedures, item-specific lexical knowledge is also used, even by beginning readers. The frequency effect was significant and did not increase with age, while stress errors on low-frequency words decreased with increasing grade. Stress neighbourhood increasingly affected stress assignment on nonwords with older children. Taken together, our findings show that both item-specific knowledge and general information about stress distribution are relevant in children's reading, suggesting the simultaneous use of both lexical and sublexical information. Moreover, as the reading system develops, and knowledge about the relative distribution of stress neighbourhood increases, larger grain-size units are also exploited.
When Being Narrow Minded is a Good Thing: Locally Biased People Show Stronger Contextual Cueing

Repeated contexts allow us to find relevant information more easily. Learning such contexts has been proposed to depend upon either global processing of the repeated contexts, or alternatively processing of the local region surrounding the target information. In this study, we measured the extent to which observers were by default biased to process towards a more global or local level. The findings showed that the ability to use context to help guide their search was strongly related to an observer's local/global processing bias. Locally biased people could use context to help improve their search better than globally biased people. The results suggest that the extent to which context can be used depends crucially on the observer's attentional bias and thus also to factors and influences that can change this bias.
WDR73 Mutations Cause Infantile Neurodegeneration and Variable Glomerular Kidney Disease

Infantile‐onset cerebellar atrophy (CA) is a clinically and genetically heterogeneous trait. Galloway–Mowat syndrome (GMS) is a rare autosomal recessive disease, characterized by microcephaly with brain anomalies including CA in some cases, intellectual disability, and early‐infantile‐onset nephrotic syndrome. Very recently, WDR73 deficiency was identified as the cause of GMS in five individuals. To evaluate the role of WDR73 mutations as a cause of GMS and other forms of syndromic CA, we performed Sanger or exome sequencing in 51 unrelated patients with CA and variable brain anomalies and in 40 unrelated patients with a diagnosis of GMS. We identified 10 patients from three CA and from two GMS families with WDR73 mutations including the original family described with CA, mental retardation, optic atrophy, and skin abnormalities (CAMOS). There were five novel mutations, of which two were truncating and three were missense mutations affecting highly conserved residues. Individuals carrying homozygous WDR73 mutations mainly presented with a pattern of neurological and neuroimaging findings as well as intellectual disability, while kidney involvement was variable. We document postnatal onset of CA, a retinopathy, basal ganglia degeneration, and short stature as novel features of WDR73‐related disease, and define WDR73‐related disease as a new entity of infantile neurodegeneration.
Detection of MYC rearrangement in high grade B cell lymphomas: correlation of MYC immunohistochemistry and FISH analysis

Summary The aim of this study was to analyse sensitivity, specificity and predictive values of recently available MYC immunohistochemistry (IHC) against the currently standard diagnostic method, fluorescence in situ hybridisation (FISH) analysis. MYC IHC and FISH analyses were performed on 30 cases of diffuse large B cell lymphoma (DLBCL) with 80% or more Ki-67 index, one case of DLBCL transformed from follicular lymphoma, three cases of B cell lymphoma intermediate between DLBCL and Burkitt lymphoma (IM), six cases of Burkitt lymphoma (BL) and one case of reactive lymph node. The inclusion criteria of high Ki-67 index, more than 80%, was imposed to exclude dependence of MYC positivity on Ki-67 positivity. The indices of specificity and positive predictive value (PPV) were low and varied widely with different thresholds of IHC positivity in percentage. At the threshold of 40% IHC positivity, specificity index was 0.45 and PPV was 0.37. At the threshold of 50% and 70% IHC positivity, specificity indices were 0.61 and 0.84, and PPVs were 0.45 and 0.67, respectively. Good sensitivity and negative predictive value (NPV) were maintained at all different thresholds. A heterogenous staining pattern of IHC was also noted. The heterogeneous IHC staining pattern observed warranted caution in interpretation and counting of IHC positive cells. MYC protein expression detected by IHC was more common than MYC translocation detected by FISH analysis. As a result, low specificity and PPV of MYC IHC, in relation to FISH analysis, were observed despite good sensitivity and NPV.
Lower Limb Prosthetic Outcome Measures: A Review of the Literature 1995 to 2005

A systematic review of outcome measures used in the field of lower limb prosthetics between 1995 and 2005 shows a multitude of measures currently in use in prosthetic rehabilitation; however, there is no agreement on a gold standard. The review was based on a search of the University of Strathclyde's RECAL database and Medline. The search strategies were liberal so as to pick up all potential studies and specific to each database. Abstracts returned by the searches were scanned for relevance by at least two of the three authors. The full text of potentially relevant studies was then obtained and considered for inclusion in the review, again by at least two authors. Any disagreement was resolved with the third author. A data extraction form covering the areas of general information, practicality, reliability, validity, scaling, and potential for bias was developed. The search identified 340 articles, of which 28 met all inclusion criteria and were included in the review. A total of 25 measures were used as primary outcome measures, with many more as comparators. Reliability, validity, and scaling data as reported in the included studies are presented. Some recurring methodological flaws were noted and include inconsistent use of numbers and percentages, insufficient information on patient populations, no analysis of difference between response and nonresponse groups, and conclusions that tend to overstate findings. No single measure emerges as being universally appropriate. There are many measures in use with little agreement regarding which to use and when. Some measures do have proven validity and reliability and are easy to use. Many of the published studies are complex and difficult to read, which may limit the transfer of research findings into clinical practice. Terminology can be inconsistent and confusing. For measuring mobility, a timed walking test that incorporates a sit-to-stand and a turn, such as the timed up and go test, is highly appropriate for amputees. Generic, nonamputee specific measures of function and quality of life are inappropriate for lower limb amputees.
Semantic classification of pictures and words

We provide new behavioural norms for semantic classification of pictures and words. The picture stimuli are 288 black and white line drawings from the International Picture Naming Project ([Székely, A., Jacobsen, T., D'Amico, S., Devescovi, A., Andonova, E., Herron, D., et al. (2004). A new on-line resource for psycholinguistic studies. Journal of Memory & Language, 51, 247–250]). We presented these pictures for classification in a living/nonliving decision, and in a separate version of the task presented the corresponding word labels for classification. We analyzed behavioural responses to a subset of the stimuli in order to explore questions about semantic processing. We found multiple semantic richness effects for both picture and word classification. Further, while lexical-level factors were related to semantic classification of words, they were not related to semantic classification of pictures. We argue that these results are consistent with privileged semantic access for pictures, and point to ways in which these data could be used to address other questions about picture processing and semantic memory.
Lady Liberty and Godfather Death as candidates for linguistic relativity? Scrutinizing the gender congruency effect on personified allegories with explicit and implicit measures

Linguistic relativity—the idea that language affects thought by way of its grammatical categorizations—has been controversially debated for decades. One of the contested cases is the grammatical gender of nouns, which is claimed to affect how their referents are conceptualized (i.e., as rather female or male in congruence with the grammatical gender of the noun), especially when used allegorically. But is this association strong enough to be detected in implicit measures, and, if so, can we disentangle effects of grammatical gender and allegorical association? Three experiments with native speakers of German tackled these questions. They revealed a gender congruency effect on allegorically used nouns, but this effect was stronger with an explicit measure (assignment of biological sex) than with an implicit measure (Extrinsic Affective Simon Task) and disappeared in the implicit measure when grammatical gender and allegorical associations were set into contrast. Taken together, these findings indicate that the observed congruency effect was driven by the association of nouns with personifications rather than by their grammatical gender. In conclusion, we also discuss implications of these findings for linguistic relativity.
Evaluation of high-definition and conventional oscillometric blood pressure measurement in anaesthetised dogs using ACVIM guidelines.

OBJECTIVES To evaluate high-definition and conventional oscillometry in comparison with direct blood pressure measurements in anaesthetised dogs. METHODS Eight simultaneous readings for systolic, diastolic and mean pressure were obtained directly and with each of two devices in nine anaesthetised dogs. Measurement procedure and validation were based on the 2007 ACVIM guidelines. RESULTS Sixty-three simultaneous readings were evaluated for each device and direct measurements. The mean differences (bias) to direct values were within 10 mmHg for both devices although bias for systolic and diastolic blood pressures was higher for Memodiagnostic. The standard deviations of differences (precision) were within 15 mmHg for Dinamap but exceeded for Memodiagnostic. Correlation coefficients were higher for Dinamap than Memodiagnostic but both failed to reach a correlation of 0.9. Over 50% of values lay within 10 mmHg of direct measures for both devices, but this percentage was greater for Dinamap than Memodiagnostic. Over 80% of values lay within 20 mmHg of direct measures for Dinamap but not for Memodiagnostic. CLINICAL SIGNIFICANCE Both devices failed to meet ACVIM guideline validation. However, Dinamap only failed with regards to correlation. Memodiagnostic failed on several requirements, and based on poor correlation, accuracy and precision, this device cannot be currently recommended for dogs under anaesthesia.
Phenotype–genotype correlations of PIGO deficiency with variable phenotypes from infantile lethality to mild learning difficulties

Inherited GPI (glycosylphosphatidylinositol) deficiencies (IGDs), a recently defined group of diseases, show a broad spectrum of symptoms. Hyperphosphatasia mental retardation syndrome, also known as Mabry syndrome, is a type of IGDs. There are at least 26 genes involved in the biosynthesis and transport of GPI‐anchored proteins; however, IGDs constitute a rare group of diseases, and correlations between the spectrum of symptoms and affected genes or the type of mutations have not been shown. Here, we report four newly identified and five previously described Japanese families with PIGO (phosphatidylinositol glycan anchor biosynthesis class O) deficiency. We show how the clinical severity of IGDs correlates with flow cytometric analysis of blood, functional analysis using a PIGO‐deficient cell line, and the degree of hyperphosphatasia. The flow cytometric analysis and hyperphosphatasia are useful for IGD diagnosis, but the expression level of GPI‐anchored proteins and the degree of hyperphosphatasia do not correlate, although functional studies do, with clinical severity. Compared with PIGA (phosphatidylinositol glycan anchor biosynthesis class A) deficiency, PIGO deficiency shows characteristic features, such as Hirschsprung disease, brachytelephalangy, and hyperphosphatasia. This report shows the precise spectrum of symptoms according to the severity of mutations and compares symptoms between different types of IGD.
Scripts and information units in future planning: Interactions between a past and a future planning task

Research on future thinking has emphasized how episodic details from memories are combined to create future thoughts, but has not yet examined the role of semantic scripts. In this study, participants recalled how they planned a past camping trip in Australia (past planning task) and imagined how they would plan a future camping trip (future planning task), set either in a familiar (Australia) or an unfamiliar (Antarctica) context. Transcripts were segmented into information units that were coded according to semantic category (e.g., where, when, transport, material, actions). Results revealed a strong interaction between tasks and their presentation order. Starting with the past planning task constrained the future planning task when the context was familiar. Participants generated no new information when the future camping trip was set in Australia and completed second (after the past planning task). Conversely, starting with the future planning task facilitated the past planning task. Participants recalled more information units of their past plan when the past planning task was completed second (after the future planning task). These results shed new light on the role of scripts in past and future thinking and on how past and future thinking processes interact.
Identification of a functional enhancer variant within the chronic pancreatitis‐associated SPINK1 c.101A>G (p.Asn34Ser)‐containing haplotype

The haplotype harboring the SPINK1 c.101A>G (p.Asn34Ser) variant (also known as rs17107315:T>C) represents the most important heritable risk factor for idiopathic chronic pancreatitis identified to date. The causal variant contained within this risk haplotype has however remained stubbornly elusive. Herein, we set out to resolve this enigma by employing a hypothesis‐driven approach. First, we searched for variants in strong linkage disequilibrium (LD) with rs17107315:T>C using HaploReg v4.1. Second, we identified two candidate SNPs by visual inspection of sequences spanning all 25 SNPs found to be in LD with rs17107315:T>C, guided by prior knowledge of pancreas‐specific transcription factors and their cognate binding sites. Third, employing a novel cis‐regulatory module (CRM)‐guided approach to further filter the two candidate SNPs yielded a solitary candidate causal variant. Finally, combining data from phylogenetic conservation and chromatin accessibility, cotransfection transactivation experiments, and population genetic studies, we suggest that rs142703147:C>A, which disrupts a PTF1L‐binding site within an evolutionarily conserved HNF1A−PTF1L CRM located ∼4 kb upstream of the SPINK1 promoter, contributes to the aforementioned chronic pancreatitis risk haplotype. Further studies are required not only to improve the characterization of this functional SNP but also to identify other functional components that might contribute to this high‐risk haplotype.
Spatial attention can be biased towards an expected dimension

A commonly held view in both exogenous and endogenous orienting is that spatial attention is associated with enhanced processing of all stimuli at the attended location. However, we often search for a specific target at a particular location, so an observer should be able to jointly specify the target identity and expected location. Whether attention can bias dimension-specific processes at a particular location is not yet clear. We used a dual task to examine the effects of endogenous spatial cues on the accuracy of perceptual judgments of different dimensions. Participants responded to a motion target and a colour target, presented at the same or different locations. We manipulated a central cue to predict the location of the motion or colour target. While overall performance in the two tasks was comparable, cueing effects were larger for the target whose location was predicted by the cue, implying that when attending a particular location, processing of the likely dimension was preferentially enhanced. Additionally, an asymmetry between the motion and colour tasks was seen; motion was modulated by attention, and colour was not. We conclude that attention has some ability to select a dimension at a particular location, indicating integration of spatial and feature-based attention.
Objects but not concepts modulate the size of the attended region

Here we investigated the types of stimuli that modulate the size of the attentional spotlight. In particular, it has been previously shown that conceptual cues that either directly refer to or are semantically related to particular spatial locations can shift attention to that location (known as “conceptual cueing”). For example, reading the word sun or joy can shift attention upward whereas the word boot or hostile can shift attention downward. Here, therefore, we tested whether words could modulate the size of the attended area. Across five experiments, we found that words that either directly referred to, or were abstractly associated with, particular sizes (small versus large) did not change the size of the attentional spotlight, whereas the presence of differently sized stimuli did, as evidenced by faster responses to targets when the spotlight is small than when it is large. This suggests that physical but not conceptual inducers can modulate the size of the attentional spotlight. This highlights an important difference between the regulation of spotlight size and shifts of attention, supporting the notion that they are subserved by distinct mechanisms.
The Isolation Rate and Antibiotic Resistant Pattern of Helicobacter Pylori in Dyspeptic Patients

In order to determine the isolation rates of Helicobacter pylori in dyspeptic patients, 167 biopsy specimens were examined using different methods, including culturing, microscopy and the rapid urease test. Resistance to commonly used antimicrobials was investigated using the disk diffusion method. Of the 167 specimens, 82(49.1%) were found to be positive for Helicobacter pylori in culture and 72(43 %) were positive in the urease biopsy test. Using Gram staining, Helicobacter pylori were observed in 43 (25.7 %) of the specimens. The resistance rate of the isolates was 53 % for metronidazol, 8% for both clarithromycin and ciprofloxacin, and 4% for tetracyline. The rate of resistance for amoxycillin was not recorded. Our results indicate that a susceptibility test is necessary before initiating therapy for Helicobacter pylori infections, otherwise treatment may be ineffective.
