Retrieval Practice Is Effective Regardless of Self-Reported Need for Cognition - Behavioral and Brain Imaging Evidence.

ABSTRACT: There is an emerging consensus that retrieval practice is a powerful way to enhance long-term retention and to reduce achievement gaps in school settings. Less is known whether retrieval practice benefits performance in individuals with low intrinsic motivation to spend time and effort on a given task, as measured by self-reported need for cognition (NFC). Here, we examined retrieval practice in relation to individual differences in NFC by combining behavioral and functional magnetic resonance imaging (fMRI) data. Using a within-subject design, upper-secondary school students (N = 274) learned a language-based material (Swahili-Swedish word-pairs), with half of the items by means of retrieval practice with feedback and half by study only. One week later, the students were tested on the word-pairs either in the classroom (n = 204), or in a fMRI scanner (n = 70). In both settings, a retrieval practice effect was observed across different levels of NFC (high or low). Relatedly, comparable fMRI effects were seen in both NFC subgroups. Taken together, our findings provide behavioral and brain-imaging evidence that retrieval practice is effective also for individuals with lower levels of NFC, which is of direct relevance for educational practice.

Project description:BackgroundSelf-reported scales and objective measurement tools are used to evaluate self-perceived and objective knowledge of evidence-based practice (EBP). Agreement between self-perceived and objective knowledge of EBP terminology has not been widely investigated among healthcare students.AimThe aim of this study was to examine agreement between self-reported and objectively assessed knowledge of EBP terminology among healthcare students. A secondary objective was to explore this agreement between students with different levels of EBP exposure.MethodsStudents in various healthcare disciplines and at different academic levels from Norway (n = 336) and Canada (n = 154) were invited to answer the Terminology domain items of the Evidence-Based Practice Profile (EBP2) questionnaire (self-reported), an additional item of 'evidence based practice' and six random open-ended questions (objective). The open-ended questions were scored on a five-level scoring rubric. Interrater agreement between self-reported and objective items was investigated with weighted kappa (Kw). Intraclass correlation coefficient (ICC) was used to estimate overall agreement.ResultsMean self-reported scores varied across items from 1.99 ('forest plot') to 4.33 ('evidence-based practice'). Mean assessed open-ended answers varied from 1.23 ('publication bias') to 2.74 ('evidence-based practice'). For all items, mean self-reported knowledge was higher than that assessed from open-ended answers (p<0.001). Interrater agreement between self-reported and assessed open-ended items varied (Kw = 0.04-0.69). The overall agreement for the EBP2 Terminology domain was poor (ICC = 0.29). The self-reported EBP2 Terminology domain discriminated between levels of EBP exposure.ConclusionAn overall low agreement was found between healthcare students' self-reported and objectively assessed knowledge of EBP terminology. As a measurement tool, the EBP2 Terminology scale may be useful to differentiate between levels of EBP exposure. When using the scale as a discriminatory tool, for the purpose of academic promotion or clinical certification, users should be aware that self-ratings would be higher than objectively assessed knowledge.

Project description:BackgroundNeed for cognition (NFC) is among the most studied personality traits in psychology. Despite its apparent relevance for engaging with technology and the use of information, it has not been studied in the context of self-monitoring systems and wearables for health. This study is the first to explore the relationship between NFC and commercial self-monitoring systems among healthy users.ObjectiveThis study aims to explore the effect of NFC levels on the selection of self-monitoring systems and evaluation of system features of self-monitoring and feedback, as well as perceived credibility and perceived persuasiveness. We also assessed perceived behavior change in the form of self-reported activity after adopting the system.MethodsSurvey data were collected in October 2019 among university students and personnel. The invitation to respond to the questionnaire was addressed to those who had used a digital system to monitor their physical activity for at least two months. The web-based questionnaire comprised the following 3 parts: details of system use, partially randomly ordered theoretical measurement items, and user demographics. The data were analyzed using structural equation modeling. The effect of NFC was assessed both as 3 groups (low, moderate, and high) and as a continuous moderator variable.ResultsIn all, 238 valid responses to the questionnaire were obtained. Individuals with high NFC reported all tested system features with statistically significantly higher scores. The NFC also had some effect on system selection. Hypothesized relationships with perceived credibility gained support in a different way for individuals with low and high NFC; for those with low NFC, credibility increased the persuasiveness of the system, but this effect was absent among individuals with high NFC. For users with high NFC, credibility was related to feedback and self-monitoring and perhaps continuously evaluated during prolonged use instead of being a static system property. Furthermore, the relationship between perceived persuasiveness and self-reported activity after adopting the system had a large effect size (Cohen f2=0.355) for individuals with high NFC, a small effect size for individuals with moderate NFC (Cohen f2=0.107), and a nonsignificant path (P=.16) for those with low NFC. We also detected a moderating effect of NFC in two paths on perceived persuasiveness but only among women. Our research model explained 59.2%, 63.9%, and 47.3% of the variance in perceived persuasiveness of the system among individuals with low, moderate, and high NFC, respectively.ConclusionsThe system choices of individuals seem to reflect their intrinsic motivations to engage with rich data, and commercial systems might themselves be a tailoring strategy. Important characteristics of the system, such as perceived credibility, have different roles depending on the NFC levels. Our data demonstrate that NFC as a trait that differentiates information processing has several implications for the selection, design, and tailoring of self-monitoring systems.

Project description:Mindfulness has been described as an inherent human capability that can be learned and trained, and its improvement has been associated with better health outcomes in both medicine and psychology. Although the role of practice is central to most mindfulness programs, practice-related improvements in mindfulness skills is not consistently reported and little is known about how the characteristics of meditative practice affect different components of mindfulness. The present study explores the role of practice parameters on self-reported mindfulness skills. A total of 670 voluntary participants with and without previous meditation experience (n = 384 and n = 286, respectively) responded to an internet-based survey on various aspects of their meditative practice (type of meditation, length of session, frequency, and lifetime practice). Participants also completed the Five Facets Mindfulness Questionnaire (FFMQ), and the Experiences Questionnaire (EQ). The group with meditation experience obtained significantly higher scores on all facets of FFMQ and EQ questionnaires compared to the group without experience. However different effect sizes were observed, with stronger effects for the Observing and Non-Reactivity facets of the FFMQ, moderate effects for Decentering in EQ, and a weak effect for Non-judging, Describing, and Acting with awareness on the FFMQ. Our results indicate that not all practice variables are equally relevant in terms of developing mindfulness skills. Frequency and lifetime practice--but not session length or meditation type--were associated with higher mindfulness skills. Given that these 6 mindfulness aspects show variable sensitivity to practice, we created a composite index (MINDSENS) consisting of those items from FFMQ and EQ that showed the strongest response to practice. The MINDSENS index was able to correctly discriminate daily meditators from non-meditators in 82.3% of cases. These findings may contribute to the understanding of the development of mindfulness skills and support trainers and researchers in improving mindfulness-oriented practices and programs.

Project description:Podocyte effacement and loss characterizes glomerulopathies such as diabetic nephropathy, lupus, and glomerular toxicity. Human primary podocyte-like epithelial cells cultured from urine (ECU) were characterized as a window to understand podocyte regeneration in these glomerulopathies. Cytokines TNF, and VEGF stimulated regrowth, whereas FGF-1 and IL1 inhibited growth, consistent with other podocyte or parietal epithelial cell models. Review of published micrographs indicated that podocyte foot processes in rodent kidneys interdigitated exclusively with foot processes from other cells, suggesting podocytes practice self-avoidance. In culture, ECU avoided close interactions with other cells arising from the same clone, until enough cells grew for the culture to become confluent. In contrast, ECU derived from multiple clones associated actively to form contiguous monolayers. Gene expression profiling of eight clonal ECU colonies using RNA sequencing revealed that each colony expressed a highly variable profile of the 53 Protocadherin genes. Variable combinations of the 53 Protocadherin PCDHA-, PCDHB-, and PCDHG- gene products are known to act homophilically to direct self-avoidance interactions in human neurons, so PCDH- genes are postulated to govern self-avoidance similarly in podocytes. Such protocadherin profiles could be considered cell names. Transcriptional profiles of ECUs suggest they may represent intermediate stages of Parietal Epithelial Cells (PECs) differentiating into podocytes. They further suggest that each podocyte practices self-avoidance, interdigitating selectively with other cells in the glomerulus. To enable further investigation of multi-clonal podocyte interactions, five podocyte clones were immortalized using temperature-sensitive SV40 Large T antigen. These results suggest that non-self interdigitation of new podocytes with remnant podocytes may facilitate replacement of dying podocytes and re-establishment of a functional filtration barrier.

Project description:IntroductionHidradenitis suppurativa (HS) is considered to be the most burdensome dermatosis, with a well-documented negative influence on quality of life (QoL). The patient's perception of the disorder, assessed as the self-reported severity, has been used in other dermatoses but not in HS. The aim of this study was to evaluate the usefulness of self-reported HS severity in clinical practice.MethodsThe study was performed on a group of 130 Spanish HS patients. HS severity was assessed for all the subjects. Hurley staging and patient self-reported severity were used. Moreover, QoL impairment was evaluated using the Dermatology Life Quality Index (DLQI) and the Hidradenitis Suppurativa Quality of Life 24 (HSQoL-24) questionnaire.ResultsThe severity of HS according to the Hurley staging was most commonly assessed as Hurley II (47.7%), indicating moderate disease, followed by severe disease (Hurley III, 26.9%) and mild disease (Hurley I, 25.4%). According to the patient self-reported HS severity, most of the patients reported having mild disease (76 patients, 58.5%), followed by moderate disease (31 patients, 23.8%). Only 23 patients (17.7%) assessed their disease as severe. Moreover, men reported mild disease significantly more frequently than women (70.9% and 49.3%, respectively; p = 0.014). The self-reported HS severity correlated positively with the effect of the disease on patient QoL assessed with DLQI (r = 0.288, p < 0.001). Likewise, a strong positive correlation was found between self-reported HS severity and QoL impairment assessed with HSQoL-24 (r = 0.404, p = 0.001). No statistically significant correlation between Hurley severity stage and DLQI or HSQoL-24 was found. Moreover, there were significant differences in both DLQI and HSQoL-24 total score between different self-reported HS severities. This was not seen for any of the QoL instruments or for Hurley severity staging.ConclusionThe results show that self-assessment severity may reflect patients' subjective feelings more adequately than popular objective instruments, and there should be a place for its use in daily clinical practice.
