OBJECTIVES: Assess implicit weight bias in children 9 to 11 years old. METHODS: Implicit weight bias was measured in children ages 9 to 11 (N = 114) by using the Affect Misattribution Procedure. Participants were shown a test image of a child for 350 milliseconds followed by a meaningless fractal (200 milliseconds), and then they were asked to rate the fractal image as "good" or "bad." We used 9 image pairs matched on age, race, sex, and activity but differing by weight of the child...

Culture is learned behavior shared among members of a group and from generation to generation within that group. In health care work, references to "culture" may also function as code for ethical uncertainty or moral distress concerning patients, families, or populations. This paper analyzes how culture can be a factor in patient-care situations that produce moral distress. It discusses three common, problematic situations in which assumptions about culture may mask more complex problems concerning family dynamics, structural barriers to health care access, or implicit bias...

It has been suggested that an age-related positivity effect may only occur in the context of explicit information processing, but it is unclear whether this bias extends to the processing of rapid facial reactions. In addition, most studies that have looked for evidence of age-related implicit positivity have used attentional (as opposed to sensory) unawareness paradigms, or used broad-based indicators of attentional awareness that do not speak to the nature of the affective response. In the present study, younger and older adults were therefore asked to view non-facial images presented supraliminally (i...

In single-step analyses, missing genotypes are explicitly or implicitly imputed, and this requires centering the observed genotypes, using the means of the unselected founders. If genotypes are only available on selected individuals, centering on the unselected founder mean is not straightforward. Here, computer simulation is used to study an alternative analysis that does not require centering genotypes but fits the mean μg of unselected individuals as a fixed effect. Centering the entire matrix of observed and imputed genotypes using their sample means can be done to improve numerical properties of the analysis, in addition to fitting μg...

The Affect Misattribution Procedure (AMP) has been forwarded as one of the most promising alternatives to the Implicit Association Test and the evaluative-priming task for measuring attitudes such as prejudice indirectly. We investigated whether the AMP is indeed able to detect an evaluative out-group bias. In contrast to recent conclusions about the robustness of AMP effects, six out of seven pilot studies indicated that participants did not show any prejudice effects in the AMP. Yet, these pilot studies were not fully conclusive with regard to our research question because they investigated different domains of prejudice, used small sample sizes, and employed a modified AMP version...

OBJECTIVE: Public attitudes and stigma toward epilepsy may limit patient motivation for treatment and participation in social activities. Stigma research requiring individuals to report personal beliefs is useful but is subject to social desirability bias. Self-reporting methods often do not capture implicit attitudes; therefore, in this study, implicit stigma was measured using the implicit association test (IAT), which is a word sorting task to minimize this bias. Recently, in Japan, several serious car accidents caused by people with epilepsy (PWE) resulted in pedestrian fatalities...

In informing decisions, utilising health technology assessment (HTA), expert elicitation can provide valuable information, particularly where there is a less-developed evidence-base at the point of market access. In these circumstances, formal methods to elicit expert judgements are preferred to improve the accountability and transparency of the decision-making process, help reduce bias and the use of heuristics, and also provide a structure that allows uncertainty to be expressed. Expert elicitation is the process of transforming the subjective and implicit knowledge of experts into their quantifiable expressions...

Molecular simulation has been used to model the detailed folding properties of peptides, yet prospective computational peptide design by such approaches remains challenging and non-trivial. To test the accuracy of simulation-based hairpin design, we characterized the folding properties of a series of so-called β-capped hairpin peptides designed to mimic a conserved hairpin of LapD, a bacterial intracellular signaling protein, both experimentally by NMR and computationally by implicit-solvent replica-exchange molecular dynamics (REMD) for three different AMBER force fields (ff96, ff99sb-ildn and ff99sb-ildn-nmr)...

This research investigated the relation between racial categorization and implicit racial bias in majority and minority children. Chinese and Indian 3- to 7-year-olds from Singapore (N = 158) categorized Chinese and Indian faces by race and had their implicit and explicit racial biases measured. Majority Chinese children, but not minority Indian children, showed implicit bias favoring own race. Regardless of ethnicity, children's racial categorization performance correlated positively with implicit racial bias...

A major goal in the analysis of complex traits is to partition the observed genetic variation in a trait into components due to individual loci and perhaps variants within those loci. However, in both QTL mapping and genetic association studies, the estimated percent variation attributable to a QTL is upwardly biased conditional on it being discovered. This bias was first described in two-way QTL mapping experiments by William Beavis, and has been referred to extensively as "the Beavis effect." The Beavis effect is likely to occur in multiparent population (MPP) panels as well as collections of sequenced lines used for genome-wide association studies (GWAS)...

Traditionally, the self-serving bias has been investigated in ambiguous contexts in which participants work on tasks that measure novel abilities before making attributions without clear criteria for success or failure feedback. Prior studies have confirmed that the self-serving bias is pervasive in the general population, yet it varies significantly across situations involving ambiguous contexts. The present study features an unambiguous context encompassing interpersonal events that involved implicit causality (with the "self" as an actor or recipient), the inherent logic of which indicated attribution criteria...

Implicit association tests (IATs) are increasingly used to indirectly assess people's traits, attitudes, or other characteristics. In addition to measuring traits or attitudes, IAT scores also reflect differences in cognitive abilities because scores are based on reaction times (RTs) and errors. As cognitive abilities change with age, questions arise concerning the usage and interpretation of IATs for people of different age. To address these questions, the current study examined how cognitive abilities and cognitive processes (i...

The goal of biological measurement is to capture underlying biological phenomena in numerical form. The reciprocity index applied to heterostylous flowers is meant to measure the degree of correspondence between fertile parts of opposite sex on complementary (inter-compatible) morphs, reflecting the correspondence of locations of pollen placement on, and stigma contact with, pollinators. Pollen of typical heterostylous flowers can achieve unimpeded fertilization only on opposite-morph flowers. Thus, the implicit goal of this measurement is to assess the likelihood of 'legitimate' pollinations between compatible morphs, and hence reproductive fitness...

Negative attitudes and discrimination against Latinos exist in the dominant U.S. culture and in healthcare systems, contributing to ongoing health disparities. This article provides findings of a pilot test of Yo Veo Salud (I See Health), an intervention designed to positively modify attitudes toward Latinos among medical trainees. The research question was: Compared to the comparison group, did the intervention group show lower levels of implicit bias against Latinos versus Whites, and higher levels of ethnocultural empathy, healthcare empathy, and patient-centeredness? We used a sequential cohort, post-test design to evaluate Yo Veo Salud with a sample of 69 medical trainees...

Disparities in the care and outcomes of US racial/ethnic minorities are well documented. Research suggests that provider bias plays a role in these disparities. The implicit association test enables measurement of implicit bias via tests of automatic associations between concepts. Hundreds of studies have examined implicit bias in various settings, but relatively few have been conducted in healthcare. The aim of this systematic review is to synthesize the current knowledge on the role of implicit bias in healthcare disparities...

BACKGROUND: Different phenomena like the spread of a disease, social interactions or the biological relation between genes can be thought of as dynamic networks. These can be represented as a sequence of static graphs (so called graph snapshots). Based on this graph sequences, classical vertex centrality measures like closeness and betweenness centrality have been extended to quantify the importance of single vertices within a dynamic network. An implicit assumption for the calculation of temporal centrality measures is that the graph sequence contains all information about the network dynamics over time...

BACKGROUND AND OBJECTIVES: Cognitive models assume that negative self-evaluations are automatically activated in individuals with Social Anxiety Disorder (SAD) during social situations, increasing their individual level of anxiety. This study examined automatic self-evaluations (i.e., implicit self-esteem) and state anxiety in a group of individuals with SAD (n = 45) and a non-clinical comparison group (NC; n = 46). METHODS: Participants were randomly assigned to either a speech condition with social threat induction (giving an impromptu speech) or to a no-speech condition without social threat induction...

In 2003, a Committee of the Institute of Medicine of the National Academy of Sciences summarized hundreds of studies documenting that US racial minorities, especially African Americans, receive poorer quality health care for a wide variety of conditions than their White counterparts. These racial differences in health care persist after controlling for sociodemographic factors and patients' ability to pay for care. The Committee concluded that physicians' unconscious negative stereotypes of African Americans, and perhaps other people of color, likely contribute to these health care disparities...

The linear ballistic accumulator (LBA) model (Brown & Heathcote, , Cogn. Psychol., 57, 153) is increasingly popular in modelling response times from experimental data. An R package, glba, has been developed to fit the LBA model using maximum likelihood estimation which is validated by means of a parameter recovery study. At sufficient sample sizes parameter recovery is good, whereas at smaller sample sizes there can be large bias in parameters. In a second simulation study, two methods for computing parameter standard errors are compared...
