The role of secondary covariates when estimating latent trait population distributions

The U.S. National Assessment of Educational Progress (NAEP), the Third International Mathematics and Science Study (TIMSS), and the U.S. Adult Literacy Survey collect probability samples of students (or adults) who are administered brief examinations in subject areas such as mathematics and reading (cognitive variables), along with background demographic (primary) and educational environment (secondary) questions. The demographic questions are used in the primary reporting, while the numerous explanatory secondary variables, or covariates, are only directly utilized in subsequent secondary analyses. The covariates are also used indirectly to create the plausible values (multiple imputations) that are an integral part of analyses because of the use of sparse matrix sampling of cognitive items. The improvement in the precision of the primary reporting due to the inclusion of the covariates is assessed here and contrasted with the precision of reporting using plausible values created using only the primary demographic variables.The results demonstrate that the improvement in precision depends on the matrix sampling designs for the cognitive assessments. The improvements range from essentially none for the most common designs, to moderate for some less common designs. Consequently, two potential changes in the reporting procedures that could improve the statistical and operational efficiency of primary reporting are (a) eliminate or reduce the collection of covariates and increase the number of cognitive items, (b) to avoid delays, eliminate the covariates from the creation of plausible values used for the primary reports, but include them later when creating public-use files for secondary analyses. The potential improvements in statistical and operational efficiency must be weighed against the intrinsic interest in the covariates, and the potential for small discrepancies in the primary and secondary reporting.Thanks to Donald Rubin, Robert Mislevy, and John Barnard for their helpful comments and computing assistance.

Attentional control in the aging brain: insights from an fMRI study of the stroop task

Several recent studies of aging and cognition have attributed decreases in the efficiency of working memory processes to possible declines in attentional control, the mechanism(s) by which the brain attempts to limit its processing to that of task-relevant information. Here we used fMRI measures of neural activity during performance of the color-word Stroop task to compare the neural substrates of attentional control in younger (ages: 21-27 years old) and older participants (ages: 60-75 years old) during conditions of both increased competition (incongruent and congruent neutral) and increased conflict (incongruent and congruent neutral). We found evidence of age-related decreases in the responsiveness of structures thought to support attentional control (e.g., dorsolateral prefrontal and parietal cortices), suggesting possible impairments in the implementation of attentional control in older participants. Consistent with this notion, older participants exhibited more extensive activation of ventral visual processing regions (i.e., temporal cortex) and anterior inferior prefrontal cortices, reflecting a decreased ability to inhibit the processing of task-irrelevant information. Also, the anterior cingulate cortex, a region involved in evaluatory processes at the level of response (e.g., detecting potential for error), showed age-related increases in its sensitivity to the presence of competing color information. These findings are discussed in terms of newly emerging models of attentional control in the human brain.     

Development of the Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM) in healthy adults

Impairments of Theory of Mind (ToM) abilities occur in a wide range of brain disorders. Therefore, reliable and ecologically valid examination of these abilities is a crucial part of any comprehensive neuropsychological assessment. An established and ecologically valid, English-language test identifying deficits in ToM abilities is “The Awareness of Social Inference Test – Social Inference Minimal (TASIT-SIM)”. However, no comparable German-language ToM test currently exists. In this study, we aimed to develop the first German-language adaption of TASIT-SIM in healthy adults. We selected 13 scenes [four scenes per message type (i.e., honesty, simple sarcasm, paradoxical sarcasm) and one practice scene] out of the 30 TASIT-SIM scenes. In collaboration with a film institute, we filmed each scene at three different intensities. These intensity version scenes were then administered to 240 healthy adults, equally distributed in sex and age, ranging from 35 to 92 years. By applying Rasch analysis, we selected intensity versions that showed neither floor nor ceiling effects in the majority of ToM questions in participants whose ToM abilities were in the medium range. In conclusion, we have developed the first German-language adaption of TASIT-SIM, i.e., the “Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM)”. The BASIT-ToM incorporates the strengths of TASIT-SIM, while overcoming its limitations such as inconsistencies in cinematic realization and ceiling effects in healthy participants. Next, the BASIT-ToM needs to be validated in healthy people and clinical populations.     

Automatic identification of storytelling responses to past-behavior interview questions via machine learning

Structured interviews often feature past-behavior questions, where applicants are asked to tell a story about past work experience. Applicants often experience difficulties producing such stories. Automatic analyses of applicant behavior in responding to past-behavior questions may constitute a basis for delivering feedback and thus helping them improve their performance. We used machine learning algorithms to predict storytelling in transcribed speech of participants responding to past-behavior questions in a simulated selection interview. Responses were coded as to whether they featured a story or not. For each story, utterances were also manually coded as to whether they described the situation, the task/action performed, or results obtained. The algorithms predicted whether a response features a story or not (best accuracy: 78%), as well as the count of situation, task/action, and response utterances. These findings contribute to better automatic identification of verbal responses to past-behavior questions and may support automatic provision of feedback to applicants about their interview performance.     

Reflecting Resiliency: Openness About Sexual Orientation and/or Gender Identity and Its Relationship to Well-Being and Educational Outcomes for LGBT Students

For lesbian, gay, bisexual, and transgender (LGBT) youth, coming out (i.e., disclosure of LGBT identity to others) can be a key developmental milestone, one that is associated with better psychological well‐being. However, this greater visibility may come with increased risk of peer victimization. Being out, therefore, may reflect resilience and may unfold differently depending on ecological context as some spaces may be more or less supportive of LGBT youth than others. This article explores a model of risk and resilience for outness among LGBT youth, including whether it varies by community context. We tested our hypothesized model with a national dataset of 7,816 LGBT secondary school students using multi‐group structural equation modeling. Consistent with our hypotheses, outness was related to higher victimization but also to higher self‐esteem and lower depression. Greater victimization was related to negative academic outcomes directly and indirectly via diminished well‐being. The increases in victimization associated with outness were larger for rural youth, and benefits to well‐being partly compensated for their lower well‐being overall. This article suggests that being out reflects resilience in the face of higher risk of victimization, in addition to promoting well‐being in other ways. Nonetheless, contextual factors influence how this model operates among LGBT youth.     

Evaluation of a Parent‐Based Intervention for At‐Risk Adolescents

This study evaluated the effectiveness of a parent‐based intervention, the Parent Project, among 84 parents of at‐risk youth. Results indicated improvements in child management, family involvement, parent–child affective quality, substance use rules communication, and parental self‐efficacy at a 10‐week follow‐up.     

Humility,stressful life events,and psychological well-being: Findings from the landmark spirituality and health survey

A growing body of research suggests that people who are more humble tend to enjoy better physical and mental health than individuals who are less humble. The next step in moving this literature forward involves explaining and empirically demonstrating how the potentially beneficial effects of humility arise. The purpose of this study is to address this issue by seeing whether humility buffers the effects of stressful life events on four measures of well-being: happiness, life satisfaction, depressed affect, and generalized anxiety disorder. Data from a new nationwide survey (N = 3010) suggest that the magnitude of the negative relationship between stressful life events and all four measures of well-being is reduced among people who are more humble. The theoretical implications of these findings are discussed.
