Measuring object recognition ability: Reliability, validity, and the aggregate z-score approach.

Measurement of domain-general object recognition ability (o) requires minimization of domain-specific variance. One approach is to model o as a latent variable explaining performance on a battery of tests which differ in task demands and stimuli; however, time and sample requirements may be prohibitive. Alternatively, an aggregate measure of o can be obtained by averaging z-scores across tests. Using data from Sunday et al., Journal of Experimental Psychology: General, 151, 676-694, (2022), we demonstrated that aggregate scores from just two such object recognition tests provide a good approximation (r = .79) of factor scores calculated from a model using a much larger set of tests. Some test combinations produced correlations of up to r = .87 with factor scores. We then revised these tests to reduce testing time, and developed an odd one out task, using a unique object category on nearly every trial, to increase task and stimuli diversity. To validate our measures, 163 participants completed the object recognition tests on two occasions, one month apart. Providing the first evidence that o is stable over time, our short aggregate o measure demonstrated good test-retest reliability (r = .77). The stability of o could not be completely accounted for by intelligence, perceptual speed, and early visual ability. Structural equation modeling suggested that our tests load significantly onto the same latent variable, and revealed that as a latent variable, o is highly stable (r = .93). Aggregation is an efficient method for estimating o, allowing investigation of individual differences in object recognition ability to be more accessible in future studies.

The state of evidence for social and emotional learning: A contemporary meta-analysis of universal school-based SEL interventions.

This article provides a systematic review and meta-analysis of the current evidence for universal school-based (USB) social and emotional learning (SEL) interventions for students in kindergarten through 12th grade available from 2008 through 2020. The sample includes 424 studies from 53 countries, reflecting 252 discrete USB SEL interventions, involving 575,361 students. Results endorsed that, compared to control conditions, students who participate in USB SEL interventions experienced significantly improved skills, attitudes, behaviors, school climate and safety, peer relationships, school functioning, and academic achievement. Significant heterogeneity in USB SEL content, intervention features, context, and implementation quality moderated student experiences and outcomes. Strengths and limitations of this evidence and implications for future USB SEL research, policy, and practice are discussed.

Empirically-Derived Effect Size Distributions of Interventions for Young Children on the Autism Spectrum.

OBJECTIVE: The purpose of this study is to present a set of empirically derived effect size distributions to provide field-based benchmarks for interpreting the observed effects of interventions for young children on the autism spectrum, and for planning future studies. METHOD: We generated effect size distributions and reported quartile values for each by outcome domain, and by boundedness, proximity, and assessment approach using 1552 effect sizes from 144 early childhood autism intervention studies gathered for a previously published meta-analysis. RESULTS: Quartile values represent considerable heterogeneity in effect size distributions across outcome domains, as well as variability as a function of outcome boundedness, proximity, and assessment approach. CONCLUSIONS: Our results serve as field- and outcome-specific benchmarks (e.g., contextual guides for small, medium, and large effects) that will help autism intervention researchers easily incorporate information from relevant prior empirical literature when conducting power analyses to plan for future studies. Benchmarks will also assist researchers seeking to interpret the magnitude of observed effects in clinical trials relative to the broader distribution of intervention effects on similar outcomes. Nuanced discussions that contextualize study findings in light of relevant empirical benchmarks will better assist practitioners in understanding the magnitude and scope of demonstrated change relative to studies with similar outcomes and selecting interventions for clinical practice. We discuss the limitations of these data, our analyses, as well as directions for future work.

Haptic object recognition based on shape relates to visual object recognition ability.

Visual object recognition depends in large part on a domain-general ability (Richler et al. Psychol Rev 126(2): 226-251, 2019). Given evidence pointing towards shared mechanisms for object perception across vision and touch, we ask whether individual differences in haptic and visual object recognition are related. We use existing validated visual tests to estimate visual object recognition ability and relate it to performance on two novel tests of haptic object recognition ability (n = 66). One test includes complex objects that participants chose to explore with a hand grasp. The other test uses a simpler stimulus set that participants chose to explore with just their fingertips. Only performance on the haptic test with complex stimuli correlated with visual object recognition ability, suggesting a shared source of variance across task structures, stimuli, and modalities. A follow-up study using a visual version of the haptic test with simple stimuli shows a correlation with the original visual tests, suggesting that the limited complexity of the stimuli did not limit correlation with visual object recognition ability. Instead, we propose that the manner of exploration may be a critical factor in whether a haptic test relates to visual object recognition ability. Our results suggest a perceptual ability that spans at least across vision and touch, however, it may not be recruited during just fingertip exploration.

Visual object recognition ability is not related to experience with visual arts.

Visual arts require the ability to process, categorize, recognize, and understand a variety of visual inputs. These challenges may engage and even influence mechanisms that are also relevant for visual object recognition beyond visual arts. A domain-general object recognition ability that applies broadly across a range of visual tasks was recently discovered. Here, we ask whether experience with visual arts is correlated with this domain-general ability. We developed a new survey to measure general visual arts experience and use it to measure arts experience in 142 individuals in whom we also estimated domain-general object recognition ability. Despite our measures demonstrating high reliability in a large sample size, we found substantial evidence (BF01 = 9.52) for no correlation between visual arts experience and general object recognition ability. This suggests that experience in visual arts has little influence on object recognition skills or vice versa, at least in our sample ranging from low to moderately high levels of arts experience. Our methods can be extended to other populations and our results should be replicated, as they suggest some limitations for the generalization of programs targeting visual literacy beyond the visual arts.

Physical therapy interventions to improve sitting ability in children with or at-risk for cerebral palsy: a systematic review and meta-analysis.

AIM: To conduct a systematic review and meta-analysis on the effectiveness of physical therapy interventions to improve sitting ability in young children with or at risk for cerebral palsy (CP). METHOD: A systematic literature search was performed using five databases. Study selection criteria were randomized controlled trials published in English on physical therapy interventions targeting sitting, reporting developmental or functional sitting outcomes, and focused on young children with or at risk for CP (mean age ≤5y). Risk of bias (ROB) was assessed using the Cochrane ROB 2.0 tool. RESULTS: Twelve unique studies met the inclusion criteria and were categorized into one of two categories: (1) comparison of two physical therapy interventions or (2) physical therapy plus adjunct versus physical therapy alone. The combined pooled effect size (g) for the 10 studies included in meta-analysis was large (g=0.78) but non-significant. Pooled effect for category 1 was small (g=-0.06) and non-significant. Interventions in category 2 showed a large and significant effect (g=1.90, p=0.022). INTERPRETATION: There is a lack of strong evidence for physical therapy interventions targeting sitting in young children with or at-risk for CP due to limitations in methodological rigor and sample sizes. Components of impairment remediation combined with functional balance training should be explored to improve sitting in children diagnosed with CP. Given the benefits of early achievement of sitting, strong evidence-based research is needed. WHAT THIS PAPER ADDS: Strong evidence is lacking for physical therapy interventions to improve sitting ability in young children with/at risk for cerebral palsy (CP). Kinesio-taping may be an effective adjunct to conventional physical therapy in improving sitting ability in children with spastic bilateral CP. Task-specific, intensive, and child-initiated intervention components show promise for improving sitting in young infants at risk for CP.

Quality is Critical for Meaningful Synthesis of Afterschool Program Effects: A Systematic Review and Meta-analysis.

Afterschool programs are designed to promote academic achievement and youth development as well as mitigate risk for students who attend. Systematic reviews have reported that afterschool programs are associated with increased academic proficiency, school bonding, prosocial behavior, and decreased problem behavior. However, the majority of meta-analyses that report on these outcomes limit their samples to only rigorously conducted studies, which is not representative of the larger literature base. This systematic review and meta-analysis is designed to extend the literature by meta-analyzing a comprehensive sample of studies and examine the impact of study quality on meta-analytical results. A comprehensive literature and effect size extraction process search yielded 130 effect sizes from 30 studies that examined the effects of afterschool programs on secondary students' academic achievement and social / behavioral development. The majority of studies were unpublished reports, and study quality in the sample represented a high risk of bias. The results confirm the hypothesis that the inclusion of lower quality studies significantly impacts overall outcomes in comparison to prior meta-analyses that have limited samples. As such, it is imperative that researchers and practitioners increase the rigor of study design across individual program evaluations so that fewer reports will be excluded. This will improve future meta-analytic outcomes by ensuring a more representative sample of the literature base. Only through improved rigor of study design will a more clear understanding of program impacts on secondary students be possible.

Sacral neuromodulation for pelvic pain and pelvic organ dysfunction: A case series.

BACKGROUND: The use of neuromodulation is growing and it is an established therapy for conditions such as bladder dysfunction. It is an increasingly used therapy for the management of chronic perineal pain but little research is currently available looking at its efficacy. AIM: We present a series of 52 patients who underwent placement of a neuromodulator, the majority of whom suffered from perineal pain, with most placements via the sacral hiatus. METHOD: Patients were asked to complete a survey recalling their symptoms prior to implantation and describing their symptoms and experience after. The majority had two leads placed via the sacral hiatus. RESULTS: Fifty-two patients had implantation of a permanent neuromodulator and 44 completed at least part of the survey. Forty-eight had leads placed via the sacral hiatus, 29 of whom had these leads only. Forty patients had perineal pain as an indicator and 32 reported that their pain improved; this difference was statistically significant (95% CI: 2.60-4.27, P < 0.001). Bladder, bowel and sexual dysfunction were reported by about half the cohort with smaller numbers of improvement for each. Thirty-five patients reported improved quality of life and 32 said they would have the procedure done again. Ten patients had the device removed. CONCLUSION: We present the largest published case series looking at the use of sacral neuromodulation as a treatment option for pelvic pain and the overall results of our audit are promising for the ongoing use and further development of this modality as a management option.

Pain after vaginal prolapse repair surgery with mesh is a post-surgical neuropathy which needs to be treated - and can possibly be prevented in some cases.

Post-surgical neuropathy leading to chronic pain is a recognised complication. It also can occur after surgery for pelvic organ prolapse repair involving mesh. Post-surgical neuropathy needs to be identified and properly treated to minimise the occurrence of chronic pain. A treatment algorithm is put forward for discussion .

Nature gives us strength: exposure to nature counteracts ego-depletion.

Previous research rarely investigated the role of physical environment in counteracting ego-depletion. In the present research, we hypothesized that exposure to natural environment counteracts ego-depletion. Three experiments were conducted to test this hypothesis. In Experiment 1, initially depleted participants who viewed pictures of nature scenes showed greater persistence on a subsequent anagram task than those who were given a rest period. Experiment 2 expanded upon this finding by showing that natural environment enhanced logical reasoning performance after ego-depleting task. Experiment 3 adopted a two- (depletion vs. no-depletion) -by-two (nature exposure vs. urban exposure) factorial design. We found that nature exposure moderated the effect of depletion on anagram task performance. Taken together, the present studies offer a viable and novel strategy to mitigate the negative impacts of ego-depletion.

Cleavage and reduced CD36 ectodomain density on heart and spleen macrophages in the spontaneously hypertensive rat.

Metabolic disease is accompanied by a range of cellular defects ("comorbidities") whose origin is uncertain. To investigate this pathophysiological phenomenon we used the Spontaneously Hypertensive Rat (SHR), which besides an elevated arterial blood pressure also has many other comorbidities, including a defective glucose and lipid metabolism. We have shown that this model of metabolic disease has elevated plasma matrix metalloproteinase (MMP) activity, which cleaves the extracellular domain of membrane receptors. We hypothesize here that the increased MMP activity also leads to abnormal cleavage of the scavenger receptor and fatty acid transporter CD36. To test this idea, chronic pharmaceutical MMP inhibition (CGS27023A) of the SHR and its normotensive control, the Wistar Kyoto Rat (WKY), was used to determine if inhibition of MMP activity serves to maintain CD36 receptor density and function. Surface density of CD36 on macrophages from the heart, spleen, and liver was determined in WKY, SHR, CGS-treated WKY (CGS WKY), and CGS-treated SHR (CGS SHR) by immunohistochemistry with an antibody against the CD36 ectodomain. The extracellular CD36 density was lower in SHR heart and spleen macrophages compared to that in the WKY. MMP inhibition by CGS served to restore the reduced CD36 density on SHR cardiac and splanchnic macrophages to levels of the WKY. To examine CD36 function, culture assays with murine macrophages (RAW 264.7) after incubation in fresh WKY or SHR plasma were used to test for adhesion of light-weight donor red blood cell (RBC) by CD36. This form of RBC adhesion to macrophages was reduced after incubation in SHR compared WKY plasma. Analysis of the supernatant macrophage media by Western blot shows a higher level of CD36 extracellular protein fragments following exposure to SHR plasma compared to WKY. MMP inhibition in the SHR plasma compared to untreated plasma, served to increase the RBC adhesion to macrophages and decrease the number of receptor fragments in the macrophage media. In conclusion, these studies bring to light that plasma in the SHR model of metabolic disease has an unchecked MMP degrading activity which causes cleavage of a variety of membrane receptors, including CD36, which attenuates several cellular functions typical for the metabolic disease, including RBC adhesion to the scavenger receptor CD36. In addition to other cell dysfunctions chronic MMP inhibition restores CD36 in the SHR.

Distinct but related abilities for visual and haptic object recognition.

People vary in their ability to recognize objects visually. Individual differences for matching and recognizing objects visually is supported by a domain-general ability capturing common variance across different tasks (e.g., Richler et al., Psychological Review, 126, 226-251, 2019). Behavioral (e.g., Cooke et al., Neuropsychologia, 45, 484-495, 2007) and neural evidence (e.g., Amedi, Cerebral Cortex, 12, 1202-1212, 2002) suggest overlapping mechanisms in the processing of visual and haptic information in the service of object recognition, but it is unclear whether such group-average results generalize to individual differences. Psychometrically validated measures are required, which have been lacking in the haptic modality. We investigate whether object recognition ability is specific to vision or extends to haptics using psychometric measures we have developed. We use multiple visual and haptic tests with different objects and different formats to measure domain-general visual and haptic abilities and to test for relations across them. We measured object recognition abilities using two visual tests and four haptic tests (two each for two kinds of haptic exploration) in 97 participants. Partial correlation and confirmatory factor analyses converge to support the existence of a domain-general haptic object recognition ability that is moderately correlated with domain-general visual object recognition ability. Visual and haptic abilities share about 25% of their variance, supporting the existence of a multisensory domain-general ability while leaving a substantial amount of residual variance for modality-specific abilities. These results extend our understanding of the structure of object recognition abilities; while there are mechanisms that may generalize across categories, tasks, and modalities, there are still other mechanisms that are distinct between modalities.

Single-case design effect-size distributions: Association with procedural parameters.

Visual analysis is historically and conventionally used to draw conclusions about outcomes in single-case studies, but researchers are increasingly using effect sizes to supplement conclusions drawn about functional relations with additional information about magnitude of behavior change. However, there is limited information about the extent to which methodological choices (i.e., design type, measurement system) may impact the magnitude of behavior change. We conducted a systematic review of interventions conducted in elementary school classrooms to characterize effect sizes for engagement behaviors and challenging behaviors in those studies. We found that researchers most often used A-B-A-B and multiple baseline across-participants designs, that a variety of measurement systems were used for engagement but not challenging behavior, and that some variability in effect-size distributions can be explained by dependent variable type, design type, and measurement system. The empirically derived distributions from this study may be helpful for single-case researchers to contextualize past, ongoing, and future work related to engagement and challenging behavior.

The relation between reading and externalizing behavior: a correlational meta-analysis.

Reading proficiency is important because it has life-long consequences and influences success in other academic areas. Many students with behavior problems are poor readers and many students with learning disabilities have more behavior problems than their typical peers. We conducted a correlational meta-analysis to examine the association between reading and externalizing behavior in students ages 5-12. We identified 33 studies that reported 88 effect sizes. Using a random-effects linear regression model with robust variance estimation, we found a significant, negative correlation (r= -0.1698, SE = 0.01, p < 0.0001) between reading and externalizing behavior. We tested several moderators related to measurement and sample characteristics. We found that rater type, behavior dimension (e.g., aggression), time between longitudinal measurement points, age of the sample, and percentage male of the sample moderated the relation between reading and behavior. Whether the reading assessment measured comprehension or word reading and socioeconomic status of the sample did not moderate the relation. Understanding the association between reading and externalizing behavior has implications for disability identification and intervention practices for children in elementary school. Future research should examine shared cognitive factors and environmental influences that explain the relation between the constructs.

Definitive single-stage surgery for treating diabetic foot osteomyelitis: a protocolized pathway including antibiotic bone graft substitute use.

BACKGROUND: Diabetic foot ulcers (DFUs) are a challenging complication of diabetes mellitus, often leading to poor clinical outcomes and significant socioeconomic burdens. We evaluated the effectiveness of a definitive single-stage protocolized surgical management pathway, including the use of local antibiotic bone graft substitute, for the treatment of infected DFUs with associated osteomyelitis. METHODS: A retrospective cohort study was conducted. Medical records were extracted (from January 2017 to December 2020) to establish a database consisting of patients who underwent surgical intervention for the treatment of an infected DFU with osteomyelitis. Patients were divided into conventional (control) and protocolized (intervention) surgical groups depending on the treatment received. Clinical outcomes were assessed over a 12-month follow-up period. RESULTS: A total of 136 consecutive patients were included (conventional = 33, protocolized = 103). The protocolized group demonstrated a statistically significant reduction in the mean number of operations performed per patient (1.2 vs. 3.5) (P < 0.001) and a shorter accumulative hospital length of stay (12.6 vs. 25.1 days) (P < 0.001) compared to the conventional group. Major amputation rates were significantly lower in the protocolized group (2% vs. 18%) (P < 0.001). Within 12 months of surgical intervention, the protocolized group exhibited an ulcer healing rate of 89%, with a low rate of recurrence (3%). CONCLUSION: The protocolized surgical pathway, including local antibiotic bone graft substitute use, demonstrated superior outcomes compared to conventional management for the treatment of infected DFUs with osteomyelitis. Further research is needed to evaluate the cost-effectiveness and generalizability of this approach.

Low-dose subcutaneous alemtuzumab is a safe and effective treatment for chronic acquired pure red cell aplasia.

Three patients with pure red cell aplasia, with or without co-existing large granular lymphocytic leukaemia, who remained transfusion-dependent despite treatment with established first-line therapy, were treated with low-dose subcutaneous alemtuzumab 15 mg twice to thrice per week, for 3 to 4 weeks. The mean response time was 17 days compared with a response time of at least 61 days on standard first-line therapy. There were no serious side-effects and the mean duration of remission was 13 months. Low-dose subcutaneous alemtuzumab is a safe and effective treatment for pure red cell aplasia and further trials should be conducted to compare the long-term effectiveness of this treatment with conventional therapy.

Application techniques for plaster of paris back slab, resting splint, and thumb spica using ridged reinforcement.

Immobilization of fractures with plaster of Paris is a mainstay of management of stable, nondisplaced fractures not requiring fixation. However, application techniques can be variable and are often ineffective after the patient is discharged because of weakness and wear of the plaster. This can lead to displacement of fractures and inadequate analgesia. We describe a simple, inexpensive, effective technique to ensure plaster strength and immobilization.

A Mixed-Methods Analysis of Speech-Language Pathologists' Executive Function Services.

PURPOSE: The purpose of this study was to examine school-based speech-language pathologists' (SLPs') implementation of services to address students' executive function (EF) needs, with particular emphasis on the prevalence and characteristics of EF interventions and the factors and barriers that influence service provision for students with EF needs. METHOD: We applied an explanatory sequential mixed-methods research design, beginning with a quantitative survey followed by a series of qualitative interviews. We analyzed the survey results using descriptive data and binary logistic regressions and used the emergent trends to inform our interview protocol, so that we could explore those trends in greater detail and context. We synthesized our quantitative and qualitative data to evaluate the characteristics of EF interventions and the factors influencing services. RESULTS: Most SLPs reported that they addressed their students' EF needs through some sort of direct or indirect intervention. Direct interventions varied by targeted domain, service delivery setting, and teaching techniques, though most SLPs favored strategy instruction and highly contextualized services. Indirect services included accommodations and consultation. SLPs commonly reported the lack of collaborative support, time, and knowledge as barriers, and most reported that professional development would be helpful to improve their services. CONCLUSIONS: Speech-language pathology graduate programs and providers of professional development should be mindful of their role in preparing SLPs to address EF needs, while SLPs may use these results to inform their own practice. Further guidance and research are necessary to elucidate the SLPs' role in mitigating the negative impact of EF challenges on students' education.

Using social network analysis in applied psychological research: A tutorial.

Social network analysis (SNA) is a highly flexible research method that allows for novel exploration of a wide variety of research phenomena. Evidence from fields as disparate as public health, education, informatics, sociology, and medicine has demonstrated the importance of recognizing the complexity inherent in individuals' connections with others. In this article, we provide a brief conceptual overview of social network theory and methodology, and then demonstrate how to apply SNA to an applied psychological research context studying students embedded in classrooms. We also provide numerous supporting materials on our OSF page, including R code for all analyses, a dataset containing social network data, and a glossary of key terms in social network analysis. We conclude with a set of recommendations for researchers interested in applying SNA to their own contexts and content areas. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Speech-Language Pathology Interventions for Children With Executive Function Deficits: A Systematic Literature Review.

PURPOSE: The purpose of this synthesis was to systematically review the research and guidance for school-based speech-language pathologists (SLPs) who provide intervention to children with developmental executive function (EF) deficits, particularly those children with co-occurring developmental language disorder (DLD). METHOD: We conducted a structured search of four major electronic databases, as well as a manual review of references and journals, which yielded 4,571 nonduplicate articles. We screened first titles and abstracts and then full texts to identify peer-reviewed articles, dissertations, and theses containing research or guidance for SLPs' interventions for children with co-occurring DLD and EF deficits; this process yielded 27 articles for analysis. We categorized these studies by type of publication and synthesized their contents to assess the evidence base for EF interventions in children with DLD and to evaluate the guidance for SLP-implemented direct and indirect interventions. RESULTS: A small body of research explores the efficacy of SLPs' intervention for children with co-occurring DLD and EF deficits, generally finding modest but inconsistent effects of cognitive interventions and strategy training to improve language outcomes. Meanwhile, nonempirical articles (e.g., tutorials) offer guidance to SLPs to support students with EF deficits through direct and indirect services. CONCLUSIONS: A growing body of literature equips SLPs with the principles and strategies of EF intervention. Many of these articles are sourced from literature about children with EF deficits or attention-deficit/hyperactivity disorder, but few empirical studies measure the efficacy of these interventions for children with co-occurring DLD.
