Investigating the Impact of Noneffortful Responses on Individual-Level Scores: Can the Effort-Moderated IRT Model Serve as a Solution?

Suboptimal effort is a major threat to valid score-based inferences. While the effects of such behavior have been frequently examined in the context of mean group comparisons, minimal research has considered its effects on individual score use (e.g., identifying students for remediation). Focusing on the latter context, this study addressed two related questions via simulation and applied analyses. First, we investigated how much including noneffortful responses in scoring using a three-parameter logistic (3PL) model affects person parameter recovery and classification accuracy for noneffortful responders. Second, we explored whether improvements in these individual-level inferences were observed when employing the Effort Moderated IRT (EM-IRT) model under conditions in which its assumptions were met and violated. Results demonstrated that including 10% noneffortful responses in scoring led to average bias in ability estimates and misclassification rates by as much as 0.15 SDs and 7%, respectively. These results were mitigated when employing the EM-IRT model, particularly when model assumptions were met. However, once model assumptions were violated, the EM-IRT model’s performance deteriorated, though still outperforming the 3PL model. Thus, findings from this study show that (a) including noneffortful responses when using individual scores can lead to potential unfounded inferences and potential score misuse, and (b) the negative impact that noneffortful responding has on person ability estimates and classification accuracy can be mitigated by employing the EM-IRT model, particularly when its assumptions are met.     

Emergent completion of multistep instructions via joint control

Teaching procedures that facilitate the emergence of novel responses allow for increased efficiency, which is critical when providing early-intervention services to children with autism spectrum disorder (ASD). Three 5- and 6-year-old children diagnosed with ASD participated. In Experiment 1, we demonstrated functional control over the effects of teaching echoic rehearsals on the emergence of completing novel two-step instructions via joint control and obtained generalization and maintenance of the effects in an applied, nontraining context. In Experiment 2, we conducted an experimental analysis of joint control by disrupting rehearsal of the instruction and tacts of the objects in the instruction, which served as the sources of joint control. Our results support the efficacy of the procedures for establishing first-trial performance with novel instructions and indicate that joint control is responsible for the emergent performance produced by our teaching procedures.     

Effect of individual thinking styles on item selection during study time allocation

The influence of individual differences on learners' study time allocation has been emphasised in recent studies; however, little is known about the role of individual thinking styles (analytical versus intuitive). In the present study, we explored the influence of individual thinking styles on learners' application of agenda‐based and habitual processes when selecting the first item during a study‐time allocation task. A 3‐item cognitive reflection test (CRT) was used to determine individuals' degree of cognitive reliance on intuitive versus analytical cognitive processing. Significant correlations between CRT scores and the choices of first item selection were observed in both Experiment 1a (study time was 5 seconds per triplet) and Experiment 1b (study time was 20 seconds per triplet). Furthermore, analytical decision makers constructed a value‐based agenda (prioritised high‐reward items), whereas intuitive decision makers relied more upon habitual responding (selected items from the leftmost of the array). The findings of Experiment 1a were replicated in Experiment 2 notwithstanding ruling out the possible effects from individual intelligence and working memory capacity. Overall, the individual thinking style plays an important role on learners' study time allocation and the predictive ability of CRT is reliable in learners' item selection strategy.     

Live training versus e‐learning to teach implementation of listener response programs

Discrete‐trial teaching is an effective teaching procedure that must be implemented with high integrity to produce optimal learning. Behavioral Skills Training (BST) has proven effective for staff training; however, BST is time and labor intensive. Computer‐based instruction (CBI) programs may provide a more efficient and cost‐effective alternative to live training if the CBI program is as effective as BST in producing accurate implementation. The current study compared CBI to BST to train novice undergraduate students to conduct discrete‐trial teaching. Participants were randomly assigned to one of the two conditions and assessed prior to and after the completion of training. Results indicated that although both BST and CBI were effective at training participants to implement discrete‐trial teaching, BST was slightly but significantly more effective whereas CBI quickly created a return on the investment of product development.     

Cumulative Adversity as a Correlate of Posttraumatic Growth: The Effects of Multiple Traumas,Discrimination, and Sexual Harassment

While trauma is, by definition, a necessary precursor of posttraumatic growth, other aspects of individuals’ life experiences affect their ability to cope with trauma, foster resilience, and grow following adversity. Most research on posttraumatic growth overlooks the accumulation of trauma and sub-trauma stressors as possible predictors of growth. In addition, most research on cumulative adversity omits all but the most extreme examples of discrimination and sexual harassment stressors. This exploratory study of 46 university students with trauma histories used measures of posttraumatic growth, trauma, major (sub-trauma) life events, chronic stressors, sexual harassment, and discrimination to examine the relationship between cumulative adversity and the development of posttraumatic growth. We found that cumulative adversity is positively correlated with posttraumatic growth, and that there are important relationships between gender, race, and cumulative adversity. A hypothesized curvilinear relationship between cumulative adversity and posttraumatic growth was not supported. These findings suggest that successfully coping with some amount of sub-trauma adversity may facilitate the development of posttraumatic growth. Additionally, sexual harassment and discrimination were closely linked to the number of chronic stressors; thus, they need to be included in measures of cumulative adversity to more fully represent the experiences of marginalized groups.     

Psychological distress in patients with chronic atrophic gastritis: the risk factors,protection factors,and cumulative effect

This study aimed to examine the psychological status among Chronic Atrophic Gastritis (CAG) patients and to find the cumulative effects of risk and protective factors. A sample of 101 CAG patients completed the investigation. Hierarchical linear regression was used to find risk and protective factors, and examine the cumulative effects in risk factor index (RFI) and protective factor index (PFI). Results showed that nine symptoms from SCL-90-R were severer among CAG patients than those in adult norm. Risk factors including positive family history of cancer and higher negative life events could predict higher GSI (β = 0.206, p = 0.023; β = 0.398, p < 0.001; R² = 0.203); more household resistant, positive coping and stronger resilience were protective factors and could predict GSI negatively (β = -0.188, p = 0.020; β = -0.350, p = 0.012; β = ?0.066, p = 0.621; R² = 0.190). The GSI was positively correlated with RFI (β = 0.338, p < 0.001; R² = 0.113) and negatively related to PFI (β = ?0.378, p < 0.001; R² = 0.133). In conclusion, CAG patients suffered from various psychological distress, and the protective factors should be enhanced cumulatively to protect against psychological distress.     

Learning Facts About Migration: Politically Motivated Learning of Polarizing Information About Refugees

Information processing during heated debates on asylum and immigration may often be influenced by prejudice rather than a desire to learn facts. In this article, we investigate how people process empirical evidence on the consequences of refugee arrivals through a novel survey experiment that disentangles politically motivated learning from other forms of learning and expressive responding. Specifically, we ask respondents to interpret a 2×2 table about the relationship between asylum seekers and crime rates. Crucially, respondents are randomly allocated to evaluate a conclusion that triggers their identity-protective stakes or not. In addition, we test for motivated responding as an alternative explanation by randomly providing some respondents with a response format that motivates them to report their inference truthfully. We find that information processing changes substantially when new information challenges existing asylum attitudes. Politically motivated learning is strongest among voters with strong negative prior attitudes towards asylum seekers. Our results also indicate that expressive responding can only partially account for this gap in correctly reported inferences. Our research has important implications for research on the consequences of refugee migration, theories of motivated reasoning, and survey methodology.     

累积情境风险与流动儿童主观幸福感的关系:个体保护因子的补偿效应和保护效应

对511名初二年级的流动儿童（平均年龄：14.37±0.78岁）及其家长进行问卷调查,考察累积情境风险与流动儿童主观幸福感的关系,及自尊、心理弹性和情绪调节等个体保护因子的作用方式差异及累积效应。结果发现：（1）累积情境风险负向预测流动儿童主观幸福感,各领域风险预测作用由大到小依次是家庭关系风险、同伴风险和学校风险,家庭社会经济地位风险预测作用不显著;（2）自尊在各领域风险与主观幸福感的关系中均发挥补偿效应;心理弹性在同伴、学校领域风险中发挥补偿效应,在家庭关系领域风险中发挥保护效应;情绪调节仅在同伴领域风险中发挥保护效应;（3）个体面临的风险数越多,具备的保护因子数越少,流动儿童主观幸福感越低。     

累积生态风险与青少年网络成瘾:心理需要满足和积极结果预期的中介作用

青少年网络成瘾与个体所处的生态背景密切相关。目前已有不少研究探讨家庭、学校、同伴背景中单个或少数风险因素对青少年网络成瘾的影响,但少有研究关注多个背景中生态风险因素的累积对青少年网络成瘾的影响及其心理机制。本研究基于累积风险模型和动机心理学理论,考察累积生态风险对青少年网络成瘾的影响及基本心理需要满足(个体在现实生活中需要被满足的情况)和积极结果预期(个体对网络使用诱因大小的判断)在其中的并行和/或链式中介作用。被试为5所中学的998名青少年。结构方程模型分析表明:(1)在控制了人口学变量后,累积生态风险对青少年网络成瘾具有显著的正向预测作用(呈"负加速模式")。(2)累积生态风险通过显著降低基本心理需要满足(表现出"梯度效应"),进而促进青少年网络成瘾。(3)累积生态风险通过显著提升积极结果预期(呈"负加速模式"),进而促进青少年网络成瘾。(4)累积生态风险对青少年网络成瘾的影响被基本心理需要满足和积极结果预期两条并行路径完全中介。上述结果表明,累积生态风险对青少年网络成瘾具有重要影响,且这种影响是通过需要和诱因两种动机力量一"推"一"拉"的合力来实现。
