Nietzsche on Honesty and the Will to Truth

ABSTRACT

Nietzsche values intellectual honesty, but is dubious about what he calls the will to truth. This is puzzling since intellectual honesty is a component of the will to truth. In this paper, I show that this puzzle tells us something important about how Nietzsche conceives of our pursuit of truth. For Nietzsche, those who pursue truth occupy unstable ground, since being honest about the ultimate reasons for that pursuit would mean that truth could no longer satisfy the important human needs it satisfies at present. We can pursue truth, or be honest about what in us is served by such a pursuit, but not both. Nietzsche aims to show that understanding and owning up to this instability is the sort of affirmation of human life to which we ought to aspire, and is the price we pay for being free from otherworldly morality.     

Subjective and physiological responses to the 35% carbon dioxide challenge in healthy and non-clinical control populations: a meta-analysis and systematic review

Background/Rationale: The carbon dioxide (CO₂) challenge has been reliably used in laboratory settings as a panicogen in clinical populations. However, the magnitude of these effects on healthy and non-clinical control populations are not clear. The aim of this meta-analysis and systematic review is to provide quantitative estimates of those effects. Specifically, the current paper will evaluate the relative efficacy of the CO₂ challenge in eliciting both subjective and physiological arousal in healthy and non-clinical control populations.

Method: A total of 16 articles with 35 independent samples were included in the meta-analysis, while 37 studies with 74 independent samples were included in the systematic review.

Results: Both the meta-analysis and systematic review found the CO₂ challenge to elicit an increase in subjective distress via self-reported anxiety and fear. Physiological responses via blood pressure and heart rate were heterogeneous in studies sampled, with no significant changes observed across studies. Moderator analyses revealed the variations in findings may be attributed to participant screening and invasive sampling.

Discussion: Findings highlight the CO₂ challenge as a useful tool in the provocation of subjective distress. Implications for both the use of the CO₂ challenge and its anticipated effects in healthy and non-clinical control populations are discussed.     

Factor structure of the CNS Vital Signs computerized cognitive battery in youth with neurological diagnoses

Computerized cognitive batteries, such as CNS Vital Signs (CNSVS), can provide valuable information in clinical and research settings. However, psychometric properties, especially in children and adolescents, remain relatively understudied. The aim of this study was to investigate the factor structure of CNSVS in children and adolescents with neurological diagnoses.

Participants with neurological diagnoses (N = 280) age 7–19 years were assessed as part of their clinical care at a tertiary hospital. All participants received the full CNSVS computerized cognitive battery, which contains seven subtests designed to measure attention, executive functioning, psychomotor speed, and memory. Principal components analyses were used to examine factor structure.

Scores from CNSVS subtests loaded onto a three-component solution and accounted for 46% of the variance. The three components were deemed to best represent (1) speed, (2) memory, and (3) inhibition, with subtest scores loading differently than the original 11 primary and secondary domain scores would have suggested.

Although the CNSVS program generates numerous primary and secondary domain scores, a three-component solution represents a more parsimonious approach to interpreting performance on the CNSVS in youth with neurological diagnoses. Confirmation of this factor solution in other samples is warranted.     

Model Selection of Nested and Non-Nested Item Response Models Using Vuong Tests

Abstract

In this paper, we apply Vuong’s general approach of model selection to the comparison of nested and non-nested unidimensional and multidimensional item response theory (IRT) models. Vuong’s approach of model selection is useful because it allows for formal statistical tests of both nested and non-nested models. However, only the test of non-nested models has been applied in the context of IRT models to date. After summarizing the statistical theory underlying the tests, we investigate the performance of all three distinct Vuong tests in the context of IRT models using simulation studies and real data. In the non-nested case we observed that the tests can reliably distinguish between the graded response model and the generalized partial credit model. In the nested case, we observed that the tests typically perform as well as or sometimes better than the traditional likelihood ratio test. Based on these results, we argue that Vuong’s approach provides a useful set of tools for researchers and practitioners to effectively compare competing nested and non-nested IRT models.     

Situational Affordances for Prosocial Behaviour: On the Interaction Between Honesty‐Humility and (Perceived) Interdependence

Individual differences in prosocial behaviour are well‐documented. Increasingly, there has been a focus on the specific situations in which particular personality traits predict prosocial behaviour. HEXACO Honesty‐Humility—the basic trait most consistently linked to prosocial behaviour in prior studies—has been found to predict prosociality most strongly in situations that afford the exploitation of others. Importantly, though, it may be the subjectively perceived situation that affords the behavioural expression of a trait. Following this reasoning, we tested the proposition that Honesty‐Humility would predict prosocial behaviour more strongly in situations characterised by, and perceived to contain, two dimensions of interdependence that can afford exploitation: high conflict and high power. However, across a series of incentivised economic games and two large experience sampling studies, we only found inconsistent evidence for the association between Honesty‐Humility and prosocial behaviour. Furthermore, the link between Honesty‐Humility and prosociality was neither conditional on objective interdependence nor on subjective perceptions of interdependence. Nonetheless, perceptions of conflict and power tracked objective properties of economic games and were related to prosocial behaviour in the lab and field. Future research should take individuals' subjective understanding of situations into account, which may also help understand the (generalisability of the) effect of Honesty‐Humility on prosocial behaviour. © 2019 The Authors.

The development of creativity in Chilean kindergarten and school children / Desarrollo de la creatividad en párvulos y escolares chilenos

Abstract

The purpose of this study is to explore the development of creativity in Chilean kindergarten and school children. For this, we evaluated non-verbal divergent and convergent thinking skills in a sample of 320 Chilean kindergarten, second-, fourth- and sixth-grade school children. We found that kindergarten and second-grade children showed a lower performance in creative fluency and originality than fourth-grade and sixth-grade children. In addition, we found that kindergarten and second-grade children had a low performance in creative elaboration, which worsened in the fourth and sixth grades. We did not find differences between the different educational levels in convergent thinking skills. Our results contradict previous international studies that report a stable development of creativity throughout the first few years of schooling, with a transitory slump in the fourth or sixth grade, revealing an early slump of creative skills in Chilean children, which rebound after the fourth grade. We discuss the potential relationship between the academization and rigidization of Chilean early childhood education and the early slump in creativity.
