Improving Psychological Measurement: Does It Make a Difference? A Comment on Nesselroade and Molenaar (2016)

Nesselroade and Molenaar advocate the use of an idiographic filter approach. This is a fixed-effects approach, which may limit the number of individuals that can be simultaneously modeled, and it is not clear how to model the presence of subpopulations. Most important, Nesselroade and Molenaar's proposal appears to be best suited for modeling long time series on a few variables for a few individuals. Long time series are not common in psychological applications. Can it be applied to the usual longitudinal data we face? These are characterized by short time series (four to five points in time), hundreds of individuals, and dozens of variables. If so, what do we gain? Applied settings most often involve between-individual decisions. I conjecture that their approach will not outperform common, simpler, methods. However, when intraindividual decisions are involved, their approach may have an edge.     

Properties of bootstrap tests for N‐of‐1 studies

N‐of‐1 study designs involve the collection and analysis of repeated measures data from an individual not using an intervention and using an intervention. This study explores the use of semi‐parametric and parametric bootstrap tests in the analysis of N‐of‐1 studies under a single time series framework in the presence of autocorrelation. When the Type I error rates of bootstrap tests are compared to Wald tests, our results show that the bootstrap tests have more desirable properties. We compare the results for normally distributed errors with those for contaminated normally distributed errors and find that, except when there is relatively large autocorrelation, there is little difference between the power of the parametric and semi‐parametric bootstrap tests. We also experiment with two intervention designs: ABAB and AB, and show the ABAB design has more power. The results provide guidelines for designing N‐of‐1 studies, in the sense of how many observations and how many intervention changes are needed to achieve a certain level of power and which test should be performed.     

Attentional orienting and executive control are affected by different types of meditation practice

Several studies have demonstrated the beneficial effects of meditation on attention. The present study investigated the relationship between focused attention (FA) and open monitoring (OM) meditation skills and the various functions of attention. In Experiment 1, we executed the attention network test and compared the performance of experts on dandao meditation with that of ordinary people on this test. The results indicated that the experts specializing in OM meditation demonstrated greater attentional orienting ability compared with those specializing in FA meditation and the control group. In addition, both expert groups registered improvements in their executive control abilities compared with the control group. In Experiment 2, we trained beginners in FA meditation for 3 months. The results showed that the experimental group exhibited significantly enhanced executive control ability. We infer that FA meditation skills promote executive control function and OM meditation skills promote both executive control and attentional orienting functions.     

Religiousness,religious coping methods,and cognitive test anxiety among African-American college students

This study explored the roles of religiousness and religious coping methods in predicting cognitive test anxiety. A convenience sample of 121 African-American students (97 females and 24 males) ranging in age from 18 to 39 (M_age?=?20.16), attending a historically Black university completed an online questionnaire assessing demographic information, religiousness, religious coping methods, and cognitive test anxiety. Results showed that negative religious coping methods were significant factors in predicting cognitive test anxiety. These relationships may be pertinent for understanding salient factors that influence cognitive test anxiety in African-American college students.     

An investigation of cognitive test performance across conditions of silence,background noise and music as a function of neuroticism

The present study investigates the role of trait neuroticism on cognitive performance under distraction. Seventy participants were given a personality test and then undertook a number of different cognitive tasks in silence, in the presence of popular music and in background noise. It was predicted that performance on a general intelligence test, a test of abstract reasoning, and a mental arithmetic task would be adversely affected by background sounds. It was predicted that neuroticism would be negatively correlated with performance on the mental arithmetic task but only when the individuals were working in the presence of background sound. Stable vs. unstable participant's performance on a mental arithmetic task during noise was significantly higher as predicted. The results provided partial support for the hypotheses and are discussed with respect to previous findings in the literature on personality (particularly introversion–extraversion) and distraction on cognitive task performance. Limitations are noted.     

TDQ-60 – a color picture-naming test for adults and elderly people: validation and normalization data

Word-finding difficulties are usually assessed with picture-naming tests. In this article, we present the TDQ-60, a new test designed to assess acquired lexical access deficits, taking into account semantics and psycholinguistic variables. The article includes three studies. Study 1 describes the development phase of the TDQ-60. In study 2, healthy control participants and individuals with a diagnosis of the semantic variant of primary progressive aphasia were assessed to establish the convergent and discriminant validity of the TDQ-60. Finally, in Study 3, a group of 305 young and elderly French-speaking adults from Quebec were assessed in order to provide normative data. The results demonstrate that the TDQ-60 has good convergent validity and good discriminant validity. This study also provides normative data in which were considered the effect of age and education.The TDQ-60 is a new valid picture-naming test, controlled for psycholinguistic variables and designed to identify the influence of semantics on lexical access in spoken production.     

Experiences in Close Relationships Revised Child version (ECR-RC): Psychometric evidence in support of a Security factor

Attachment refers to the innate tendency to form strong and close interpersonal bonds, from infancy through adulthood. Many different ways to assess attachment have been developed, one of them being the use of self-report questionnaires. The Experiences in Close Relationships-Revised is one of the most commonly used instruments to assess adult and late adolescent attachment. Recently, a new and brief child version of this instrument has been published, the 12-item ECR-RC short form. The purpose of the current study was threefold: (1) to test the factorial structure of this form in a sample of Italian adolescents, (2) to test the loadings overlap between the mother and the father forms, and (3) to investigate factors reliability. Using a sample of 961 adolescents (M_age = 14.25, SD_age = 1.57), a series of Confirmatory Factor Analyses were performed. The Avoidance – Anxiety structure was not supported, whereas a factor structure including Anxiety, Avoidance, and Security, had a very good fit. Item loadings on these factors were largely equal across mother and father, and internal reliability was high. The results of this study show that the ECR-RC short form is a quick and reliable way to assess attachment in early adolescents. This study also initiates the proposal of an ECR-RC Security factor, to be further validated in future studies.     

Dissecting the expanded cognitive reflection test: an item response theory analysis

This study presents a psychometric evaluation of the Expanded Cognitive Reflection Test (CRT7) based on item response theory. The participants (N?=?1204) completed the CRT7 and provided self-reported information about their cognitive styles through the Preference for Intuition and Deliberation Scale (PID). A two-parameter logistic model was fitted to the data to obtain the item difficulty and discrimination parameters of the CRT7. The results showed that the items had good discriminatory power (αs?=?.80 ? 2.92), but the range of difficulty was restricted (βs ranged from ?.60 to .32). Moreover, the CRT7 showed a pattern of correlations with the PID which was similar to that of the original CRT. When taken together, these results are evidence of the adequacy of the CRT7 as an expanded tool for measuring cognitive reflection; however, one of the newer items (the pig item) was consistently problematic across analyses, and so it is recommended that in future studies it should be removed from the CRT7.
