In the task-switching paradigm, the latency switch-cost score—the difference in mean reaction time between switch and nonswitch trials—is the traditional measure of task-switching ability. However, this score does not reflect accuracy, where switch costs may also emerge. In two experiments that varied in response deadlines (unlimited vs. limited time), we evaluated the measurement properties of two traditional switch-cost scoring methods (the latency switch-cost score and the accuracy switch-cost score) and three alternatives (a rate residual score, a bin score, and an inverse efficiency score). Scores from the rate residual, bin score, and inverse efficiency methods had comparable reliability for latency switch-cost scores without response deadlines but were more reliable than latency switch-cost scores when higher error rates were induced with a response deadline. All three alternative scoring methods appropriately accounted for differences in accuracy switch costs when higher error rates were induced, whereas pure latency switch-cost scores did not. Critically, only the rate residual and bin score methods were more valid indicators of task-switching ability; they demonstrated stronger relationships with performance on an independent measure of executive functioning (the antisaccade analogue task), and they allowed the detection of larger effect sizes when examining within-task congruency effects. All of the three alternative scoring methods provide researchers with a better measure of task-switching ability than do traditional scoring methods, because they each simultaneously account for latency and accuracy costs. Overall, the three alternative scoring methods were all superior to the traditional latency switch-cost scoring method, but the strongest methods were the rate residual and bin score methods. 相似文献
Psychological factors have an impact on subjective pain experience. The aim of this study was to explore the occurrence of alexithymia and Early Maladaptive Schemas in a sample of 271 first visit chronic pain patients of six pain clinics. The patients completed the study questionnaire consisting of the Toronto Alexithymia Scale‐20, the Finnish version of the Young Schema Questionnaire short form‐extended, the Beck Depression Inventory‐II, and pain variables. Alexithymic patients scored higher on Early Maladaptive Schemas and had more pain intensity, pain disability and depression than nonalexithymic patients. Both alexithymia and depression correlated significantly with most Early Maladaptive Schemas. The co‐occurrence of alexithymia, Early Maladaptive Schemas and depression seems to worsen the pain experience. Screening of alexithymia, depression and Early Maladaptive Schemas may help to plan psychological treatment interventions for chronic pain patients. 相似文献
African American women are often times characterized by stereotypes that can be traced back to slavery. Those stereotypes have been found to affect many outcomes in an array of domains related to work, intimate relationships, and personal well-being. The literature does not address how these stereotypes may affect adolescent African American girls. This study aimed to fill that gap by examining how the endorsement of stereotypes affects the psychological well-being, specifically stress, in 144 African American adolescent girls (N = 144) who ranged from 12–19 years old. This study goes a step further to investigate whether collective self-esteem can serve as a buffer between endorsement of stereotypes and perceived stress. Using combined mediation–moderation model, the analysis showed that there is a significant positive relationship between stereotypic beliefs and perceived stress that is buffered by moderate to high levels of collective self-esteem. Implications for treatment and policy, as well as educational recommendations are discussed. 相似文献
The most common result of BRCA1/2 mutation testing when performed in a family without a previously identified mutation is an uninformative negative test result. Women in these families may have an increased risk for breast cancer because of mutations in non-BRCA breast cancer predisposition genes, including moderate- or low-risk genes, or shared environmental factors. Genetic counselors often encourage counselees to share information with family members, however it is unclear how much information counselees share and the impact that shared information may have on accuracy of risk perception in family members. We evaluated 85 sisters and daughters of women who received uninformative negative BRCA1/2 results. We measured accuracy of risk perception using a latent variable model where accuracy was represented as the correlation between perceived risk (indicators = verbal and quantitative measures) and calculated risk (indicators = Claus and BRCAPRO). Participants who reported more information was shared with them by their sister or mother about her genetic counseling session had greater accuracy of risk perception (0.707, p?=?0.000) than those who reported little information was shared (0.326, p?=?0.003). However, counselees shared very little information; nearly 20 % of family members reported their sister or mother shared nothing with them about her genetic counseling. Family members were generally not aware of the existence of a genetic counseling summary letter. Our findings underscore the need for effective strategies that facilitate counselees to share information about their genetic counseling sessions. Such communication may help their relatives better understand their cancer risks and enhance risk appropriate cancer prevention. 相似文献
We examined citations of Murray Sidman's publications in the Journal of the Experimental Analysis of Behavior from the journal's inception in 1958 through May 2020. On average, he was cited 35.6 times per year. The rate of citation did not change substantially across time and the cumulative citation count was 2,212. His 10 publications cited most often deal with behavior-analytic research methods, stimulus equivalence, and unsignaled free-operant (or Sidman) avoidance. Our data provide clear evidence of the breadth and depth of Sidman's influence on the experimental analysis of behavior across 7 decades. His contributions were both exceptional and praiseworthy and his legacy will long endure. 相似文献
To further advance assessment of patient-reported outcomes, the European Organisation of Research and Treatment of Cancer (EORTC) Quality of Life Group has developed computerized adaptive test (CAT) versions of all EORTC Quality of Life Core Questionnaire (QLQ-C30) scales/items. The aim of this study was to develop and evaluate an item bank for CAT measurement of insomnia (CAT-SL). In line with the EORTC guidelines, the developmental process comprised four phases: (I) defining the concept insomnia and literature search, (II) selection and formulation of new items, (III) pre-testing and (IV) field-testing, including psychometric analyses of the final item bank. In phase I, the literature search identified 155 items that were compatible with our conceptualisation of insomnia, including both quantity and quality of sleep. In phase II, following a multistep-approach, this number was reduced to 15 candidate items. Pre-testing of these items in cancer patients (phase III) resulted in an item list of 14 items, which were field-tested among 1094 patients in phase IV. Psychometric evaluations showed that eight items could be retained in a unidimensional model. The final item bank yielded greater measurement precision than the original QLQ-C30 insomnia item. It was estimated that administering two or more items from the insomnia item bank with CAT results in a saving in sample size between approximately 15–25%. The 8-item EORTC CAT-SL item bank facilitates precise and efficient measurement of insomnia as part of the EORTC CAT system of health-related quality life assessment in both clinical research and practice.
Do the processing and online manipulation of stimuli that are less familiar require more working memory (WM) resources? Is it more difficult to solve demanding problems when the symbols involved are less rather than more familiar? We explored these questions with a dual-task paradigm in which subjects had to solve algebra problems of different complexities while simultaneously holding novel symbol–digit associations in WM. The symbols were previously unknown Chinese characters, whose familiarity was manipulated by differential training frequency with a visual search task for nine hour-long sessions over 3 weeks. Subsequently, subjects solved equations that required one or two transformations. Before each trial, two different integers were assigned to two different Chinese characters of the same training frequency. Half of the time, those characters were present as variables in the equation and had to be substituted for the corresponding digits. After attempting to solve the equation, subjects had to recognize which two characters were shown immediately before that trial and to recall the integer associated with each. Solution accuracy and response times were better when the problems required one transformation only; variable substitution was not required; or the Chinese characters were high frequency. The effects of stimulus familiarity increased as the WM demands of the equation increased. Character–digit associations were also recalled less well with low-frequency characters. These results provide strong support that WM capacity depends not only on the number of chunks of information one is attempting to process but also on their strength or familiarity. 相似文献
Mixed-sexuality marriages (MSMs) are defined in the present study as those where one partner identifies as heterosexual and the other partner identifies as gay, lesbian, bisexual, queer or reports experiencing same-sex attraction. Members of conservative religions, such as Mormonism, may be more likely to enter MSMs given the religion’s stance on homosexuality and doctrinal emphasis on heteronormative marriage. Using data from 56 interviews with individuals who either have been or currently are Mormon and in a MSM, we explore participants’ ideas about gender roles and sexuality in the context of their ideas about Mormonism. We find that couples’ ideas about gender, sexuality, and religion intersect to act as a resource or impediment to marital satisfaction. Among our sample, most couples maintain an outward appearance of heteronormativity; some view their private departure from the traditional gender order as a benefit to their relationship, whereas others view it as a source of strain and work hard to minimize gender deviance in their roles. The findings provide an important example of the way gender and religion are mutually constitutive and illustrate how notions of sexuality are sometimes used to reinforce a traditional gender order and religious beliefs, whereas at other times, the contradictions of MSMs challenge traditional gender norms and religious orthodoxy. 相似文献
