Although it has long been acknowledged that interviewers play a crucial role in the survey data collection process, there is little research concerning interviewer effects on how respondents perceive the interview. We investigate whether interviewer effects exist regarding how much respondents report having enjoyed the interview and whether these…

A general framework of latent trait item response models for continuous responses is given. In contrast to classical test theory (CTT) models, which traditionally distinguish between true scores and error scores, the responses are clearly linked to latent traits. It is shown that CTT models can be derived as special cases, but the model class is…

Evidence for implicit aversive learning effects has been criticized for its lack of experimental rigor and statistical reliability. Here we examine whether attentional emotional responses to aversive conditioned stimuli can occur in the absence of stimulus-outcome contingency awareness, and use a novel Bayesian tool to reliably perform a post hoc…

Understanding the cognitive processes, skills and strategies that examinees use in testing is important for construct validity and score interpretability. Although response processes evidence has long been included as an important aspect of validity (i.e., "Standards for Educational and Psychological Tests," 1999), relevant studies are…

Low test-taking effort of examinees has been considered a source of construct-irrelevant variance in item response modeling, leading to serious consequences on parameter estimation. This study aims to investigate how non-effortful response (NER) influences the estimation of item and person parameters in item-pool scale linking (IPSL) and whether…

Sensory over-responsivity in the vestibular domain (aka gravitational insecurity) has been frequently identified in the literature. However, little has been written about the effectiveness of interventions, especially in toddlers with these idiopathic challenges (e.g. without a diagnosis of autism). The objective of this pilot study was to test…

Stimulus-response binding and retrieval (SRBR) is a fundamental mechanism driving behavior automatization. In five experiments, we investigated the modulatory role of affective consequences (AC) on SRBR effects to test whether binding/retrieval can explain instrumental learning (i.e., the "law of effect"). SRBR effects were assessed in a…

For large-scale assessments, data are often collected with missing responses. Despite the wide use of item response theory (IRT) in many testing programs, however, the existing literature offers little insight into the effectiveness of various approaches to handling missing responses in the context of scale linking. Scale linking is commonly used…

Data collected during psychoeducational evaluations can be compromised by response bias: clients not putting forth sufficient effort on tests, not being motivated to do well, or not being fully honest and careful when completing rating scales and contributing similar self-report data. Some of these problems apply to data from third-party…

When a highly salient distractor is present in a search array, it speeds target absent visual search and increases errors during target present visual search, suggesting lowered quitting thresholds (Moher in Psychol Sci 31(1):31-42, 2020). Missing a critical target in the presence of a highly salient distractor can have dire consequences in…

Thurstonian forced-choice modeling is considered to be a powerful new tool to estimate item and person parameters while simultaneously testing the model fit. This assessment approach is associated with the aim of reducing faking and other response tendencies that plague traditional self-report trait assessments. As a result of major recent…

Objective: To compare neurofunctional responses in emotional and attentional networks of psychostimulant-free ADHD youth with and without familial risk for bipolar I disorder (BD). Methods: ADHD youth with (high-risk, HR, n = 48) and without (low-risk, LR, n = 50) a first-degree relative with BD and healthy controls (n = 46) underwent functional…

Infants' prelinguistic vocalizations reliably organize vocal turn-taking with social partners, creating opportunities for learning to produce the sound patterns of the ambient language. This social feedback loop supporting early vocal learning is well-documented, but its developmental origins have yet to be addressed. When do infants learn that…

Little research has used in vivo, naturalistic observations to understand developmental processes related to bullying in early childhood. To test associations between how young children respond to experiences of peer victimization and changes in relational and physical bullying behaviors, a short-term longitudinal study using behavioral…

Bounded continuous data are encountered in many applications of item response theory, including the measurement of mood, personality, and response times and in the analyses of summed item scores. Although different item response theory models exist to analyze such bounded continuous data, most models assume the data to be in an open interval and…
