The Generalizability of Personality Effects in Politics

A burgeoning line of research examining the relation between personality traits and political variables relies extensively on convenience samples. However, our understanding of the extent to which using convenience samples challenges the generalizability of these findings to target populations remains limited. We address this question by testing whether associations between personality and political characteristics observed in representative samples diverged from those observed in the sub‐populations most commonly studied in convenience samples, namely, students and Internet users. We leverage 10 high‐quality representative datasets to compare the representative samples with the two subsamples. We did not find any systematic differences in the relationship between personality traits and a broad range of political variables. Instead, results from the subsamples generalized well to those observed in the broader and more diverse representative sample.     

Testing primary‐school children's understanding of the nature of science

Understanding the nature of science (NOS) is a critical aspect of scientific reasoning, yet few studies have investigated its developmental beginnings and initial structure. One contributing reason is the lack of an adequate instrument. Two studies assessed NOS understanding among third graders using a multiple‐select (MS) paper‐and‐pencil test. Study 1 investigated the validity of the MS test by presenting the items to 68 third graders (9‐year‐olds) and subsequently interviewing them on their underlying NOS conception of the items. All items were significantly related between formats, indicating that the test was valid. Study 2 applied the same instrument to a larger sample of 243 third graders, and their performance was compared to a multiple‐choice (MC) version of the test. Although the MC format inflated the guessing probability, there was a significant relation between the two formats. In summary, the MS format was a valid method revealing third graders' NOS understanding, thereby representing an economical test instrument. A latent class analysis identified three groups of children with expertise in qualitatively different aspects of NOS, suggesting that there is not a single common starting point for the development of NOS understanding; instead, multiple developmental pathways may exist.     

Führt die evolutionäre Erkenntnistheorie in einen Relativismus?

This essay is a discussion of Eve-Marie Engels' view on Evolutionary Epistemology (EE). In the first part two of the main doctrines of EE are criticized: (1.) that validity of human knowledge is to be explained as the result of evolutionary adaptation; yet (2.), that human cognitive capacities had been adequate to our ancestors life conditions but fail in relevant situations of modern world. In the second part the concept of reality underlying EE's adaptational view is discussed and compared with Jean Piaget's concept of reality. Finally, it is held that some of the questions recently raised by proponents of EE, far from being new, have been dealt with already in historical epistemology.

Further evidence for the validity of the Need Inventory of Sensation Seeking

The Need Inventory of Sensation Seeking (NISS) by Roth and Hammelstein (2012) conceptualizes sensation seeking as a motivational trait, a need for stimulation that can provoke different behaviors. Extending the area of application to the field of sexuality, the results of an online survey with a convenience sample (N = 368) provided evidence that the NISS outperforms traditional measures of sensation seeking. In a series of hierarchical regression analyses, the NISS added incremental variance in predicting the number of sexual partners and the frequency of extreme sexual behaviors and fantasies. No relationship between the NISS and pornography use was found. Moreover, the NISS subscale Need for Stimulation performed better than the subscale Avoidance of Rest. Overall, the study supported the assumption that the NISS is a valid and reliable instrument in the area of sexuality.     

Beyond congruence measures for the evaluation of personality factor structure replicability: An exploratory structural equation modeling approach

The present study aims to illustrate an encompassing approach to the evaluation of personality factor structure replicability based on novel exploratory structural equation modeling (ESEM) methods. This approach comprises formal tests of measurement invariance applied to the flexible ESEM framework and overcomes the limitations of congruence measures that have traditionally been used to assess factor replicability in personality research. On the basis of 1566 responses to the widely-used NEO Five-Factor-Inventory (NEO-FFI), we demonstrate this ESEM approach in the context of examining the invariance of the NEO-FFI factor structure across gender. The approach is shown to converge with traditional congruence measures and extend these measures for examining factorial structure consistency. In addition, more general replicative data supporting the validity of the NEO-FFI are reported. We discuss the ESEM approach as a viable alternative to the congruence approach and acknowledge some important limitations of the method.     

Parent-report measure of Theory of Mind: Adaptation to Polish of the Children’s Social Understanding Scale

The main aim of the study was to investigate whether the Children’s Social Understanding Scale (CSUS), a parent report technique, is a valid and reliable measure of Theory of Mind (ToM) abilities in Polish-speaking children. Additionally, the role of language abilities in ToM development was explored. A group of 225 parents of approximately 3.5-year-old Polish children was tested using the Polish version of the CSUS. Their children were tested with a word comprehension test and five behavioural ToM tasks. Satisfactory psychometric properties of the Polish CSUS were observed and positive correlations between the CSUS and behavioural ToM tasks were found. A two-factor structure was found in the CSUS: Mental State Talk (MST) and Mental State Comprehension. The MST factor was significantly related to word comprehension. The utility of the Polish version of the CSUS for future cross-cultural research with this population is discussed.     

The criterion-related validity of conscientiousness in personnel selection: A meta-analytic reality check

A key finding in personnel selection is the positive correlation between conscientiousness and job performance. Evidence predominantly stems from concurrent validation studies with incumbent samples but is readily generalized to predictive settings with job applicants. This is problematic because the extent to which faking and changes in personality affect the measurement likely vary across samples and study designs. Therefore, we meta-analytically investigated the relation between conscientiousness and job performance, examining the moderating effects of sample type (incumbent vs. applicant) and validation design (concurrent vs. predictive). The overall correlation of conscientiousness and job performance was in line with previous meta-analyses ($\overline{r}=.17,k=102,n=23,305$). In our analyses, the correlation did not differ across validation designs (concurrent: $\overline{r}=.18,k=78,n=19,132$; predictive: $\overline{r}=.15,k=24,n=4173$), sample types (incumbents: $\overline{r}=.18,k=92,n=20,808$; applicants: $\overline{r}=.14,k=10,n=2497$), or their interaction. Critically, however, our review revealed that only a small minority of studies (~12%) were conducted with real applicants in predictive designs. Thus, barely a fraction of research is conducted under realistic conditions. Therefore, it remains an open question if self-report measures of conscientiousness retain their predictive validity in applied settings that entail faked responses. We conclude with a call for more multivariate research on the validity of selection procedures in predictive settings with actual applicants.     

Improving theory,measurement, and reality to advance the future of emotion research

ABSTRACT

In this short contribution, I reflect on three domains I think are important to advance emotion research. The first concerns theoretical progress, which I hope will occur in the form of theoretical unification that will allow for a consensual definition and understanding of its main object of study. The second concerns measurement where in parallel to technological advances to measure behaviour and biology, particularly the measurement of experience deserves more attention. The third concerns reality, where I advocate the need to study real-world phenomena.     

Confirmatory factor analysis of the five-item version of the Francis scale of attitude towards Christianity in adolescent students

ABSTRACT

The brief scale of Francis for religiosity (Francis-5) has shown acceptable psychometric performance in Colombian adolescents. However, a confirmatory factorial analysis (CFA) has not been performed. The objective of the researche was to make a CFA to the Francis-5 in a sample of students of Santa Marta, Colombia. A validation study was performed. 350 students between 10 and 17 years old, and 54% were female. A CFA was performed to test the dimensionality of different versions of five and four items of the scale. Authors calculated five goodness of fit indexes indices (Chi square, RMSEA, CFI, TLI, and SMSR). The Francis-5 presented as goodness-of-fit coefficients, chi squared = 18.5, gl = 5, p = .002, RMSEA = .09 (CI90% .05 to .13), CFI = .99, TLI = .99, and SMSR = .01. And the version with the best coefficients of goodness was the Francis-5 without the fourth item (‘Pray helps me a lot’) with chi squared = .55, gl = 2, p = .76, RMSEA = .00 (CI90% .00 to .07), CFI = 1.00, TLI = 1.00, and SMSR = .01. As conclusions, the dimensionality of the Francis-5 is questionable. For a version without the item 4 the data are better fit.
