The validity of psychomotor vigilance tasks of less than 10-minute duration.

The 10-min psychomotor vigilance task (PVT) has often been used to assess the impact of sleep loss on performance. Due to time constraints, however, regular testing may not be practical in field studies. The aim of the present study was to examine the suitability of tests shorter than 10 min. in duration. Changes in performance across a night of sustained wakefulness were compared during a standard 10-min PVT, the first 5 min of the PVT, and the first 2 min of the PVT. Four performance metrics were assessed: (1) mean reaction time (RT), (2) fastest 10% of RT, (3) lapse percentage, and (4) slowest 10% of RT. Performance during the 10-min PVT significantly deteriorated with increasing wakefulness for all metrics. Performance during the first 5 min and the first 2 min of the PVT deteriorated in a manner similar to that observed for the whole 10-min task, with all metrics except lapse percentage displaying significant impairment across the night. However, the shorter the task sampling time, the less sensitive the test is to sleepiness. Nevertheless, the 5-min PVT may provide a viable alternative to the 10-min PVT for some performance metrics.     

Bicultural identities: The interface of cultural, personality, and socio-cognitive processes

This paper presents recent work examining the meaning and impact of individual variations in the way bicultural individuals organize their two cultural identities, a construct that we call Bicultural Identity Integration (BII). While biculturals high on BII describe their two cultural identities as ‘compatible’ (fluid and complementary), biculturals low on BII experience them as largely ‘oppositional’ (i.e., conflicting and disparate). We first report experimental evidence for how variations in BII moderate biculturals’ socio-cognitive behavior, specifically, the way in which bicultural individuals process cultural knowledge and use it to interpret social behavior. We then report structural equation modeling findings that elucidate some important personality, contextual, and performance predictors of BII. Finally, we conclude with a brief discussion of how the study of bicultural identities provides an ideal ground for the integration of cultural and personality psychology.     

Can Life Be Meaningful without Free Will?

Philosophia - If we lack deep free agency, like that supposed by metaphysical libertarianism, should we view life as meaningless, pointless, or not worth living? Here I present a new argument in...     

Adaptation of the Mullen Scales of Early Learning for use among infants aged 5‐ to 24‐months in rural Gambia

Infants in low‐resource settings are at heightened risk for compromised cognitive development due to a multitude of environmental insults in their surroundings. However, the onset of adverse outcomes and trajectory of cognitive development in these settings is not well understood. The aims of the present study were to adapt the Mullen Scales of Early Learning (MSEL) for use with infants in a rural area of The Gambia, to examine cognitive development in the first 24‐months of life and to assess the association between cognitive performance and physical growth. In Phase 1 of this study, the adapted MSEL was tested on 52 infants aged 9‐ to 24‐months (some of whom were tested longitudinally at two time points). Further optimization and training were undertaken and Phase 2 of the study was conducted, where the original measures were administered to 119 newly recruited infants aged 5‐ to 24‐months. Infant length, weight and head circumference were measured concurrently in both phases. Participants from both phases were split into age categories of 5–9 m (N = 32), 10–14 m (N = 92), 15–19 m (N = 53) and 20–24 m (N = 43) and performance was compared across age groups. From the ages of 10–14 m, Gambian infants obtained lower MSEL scores than US norms. Performance decreased with age and was lowest in the 20–24 m old group. Differential onsets of reduced performance were observed in the individual MSEL domains, with declines in visual perception and motor performance detected as early as at 10–14 months, while reduced language scores became evident after 15–19 months of age. Performance on the MSEL was significantly associated with measures of growth.     

Is Confucianism a religion? Modern Confucian theories on the ethical nature of classical discourses

When dealing with the study of diverse Confucian traditions in eastern Asia, we are often confronted by the issue of the religious dimension of Confucianism and how can it be compared to the Western (or ‘general’) connotations of the term. Proceeding from the basic question as to how Confucianism sees itself, the paper focuses on the approaches of two representatives of the Modern Confucian intellectual movement, namely Mou Zongsan and Xu Fuguan. In addition, we shall also take into consideration the various contemporary Confucian interpretations of the previously delineated problems, for instance Liu Shu-hsien’s or Chen Lai’s. Based on these discourses, the paper clarifies the reasons for Modern Confucian interpretations, according to which Confucianism is not a religion in the Western sense but a discourse that represents both a practical moral teaching and an abstract philosophy of immanent transcendence.     

Keeping up day-specific effects of transformational leadership: the role of followers’ emotion regulation

This diary study examines the role of day-specific transformational leadership for followers’ personal initiative. Building on Affective Events Theory, we proposed a direct effect of day-specific transformational leadership on followers’ personal initiative on the same day. Furthermore, we took a closer look at lagged effects of day-specific transformational leadership. More specifically, we hypothesized that positive effects of one day’s transformational leadership can endure until the next day for followers who apply beneficial emotion regulation strategies. We conducted a diary study over five consecutive working days among 97 employees. Two-level hierarchical linear modelling supported our hypotheses. As expected, day-specific transformational leadership positively predicted followers’ personal initiative on the same day. Furthermore, concerning the association between day-specific transformational leadership and followers’ personal initiative on the following day, there was a positive relation for followers applying beneficial emotion regulation strategies in terms of high cognitive reappraisal and low expressive suppression, respectively.     

Music is awesome: Influences of emotion,personality, and preference on experienced awe

Awe is a complex, cognitive–conceptual emotion associated with transcendence and wonder. Music has the power to create this kind of transcendence. Can music evoke awe? Previous research demonstrates that awe is associated with individual differences in personality such as openness. This study examined whether different kinds of music across a wide variety of genres can evoke awe and whether the experience of awe depends on individual differences. The study further investigated the relationship of awe to patterns of emotional responses to different dimensions of musical genre. Study 1 demonstrated that high need for cognition and low cognitive closure predicted awe for reflective and complex music, that felt happiness predicted awe for all kinds of music, and that perceived happiness and sadness predicted awe only for reflective and complex music. Study 2 replicated the finding that perceived sadness can evoke awe in reflective and complex music and further demonstrated that experienced musical awe correlates with individual differences in the tendency to experience awe more generally. These results are of interest to advertisers interested in evoking awe with music and marketers interested in segmenting to target the appropriate populations for this purpose.     

Intra-EU Migration: Legal and Economic View on Jobseekers’ Welfare Rights

International migration influences economies of both the home and the host country. Some countries perceive immigration as a threat and consider limitations to their social security system to protect the domestic economy. Within the European Union, both the economic and the legal side of the issue must be taken into account. The paper presents an empirical analysis of natives’ and immigrants’ unemployment rates in EU15 countries and discusses a possible use of the findings in intra-EU migration policy. Using Labour Force Survey Data for 2012, we estimate a series of logistic regressions in order to compare the immigrant/native unemployment rates, considering the differences in the structure of both subpopulations (in terms of age, sex, education and types of jobs). We conclude that a substantial part of the gap between natives’ and immigrants’ unemployment rates can be explained by these additional characteristics in most of the EU15 countries.     

Pornography use and sexual aggression: the impact of frequency and type of pornography use on recidivism among sexual offenders

In this study, we examined the unique contribution of pornography consumption to the longitudinal prediction of criminal recidivism in a sample of 341 child molesters. We specifically tested the hypothesis, based on predictions informed by the confluence model of sexual aggression that pornography will be a risk factor for recidivism only for those individuals classified as relatively high risk for re-offending. Pornography use (frequency and type) was assessed through self-report and recidivism was measured using data from a national database from the Royal Canadian Mounted Police. Indices of recidivism, which were assessed up to 15 years after release, included an overall criminal recidivism index, as well as subcategories focusing on violent (including sexual) recidivism and sexual recidivism alone. Results for both frequency and type of pornography use were generally consistent with our predictions. Most importantly, after controlling for general and specific risk factors for sexual aggression, pornography added significantly to the prediction of recidivism. Statistical interactions indicated that frequency of pornography use was primarily a risk factor for higher-risk offenders, when compared with lower-risk offenders, and that content of pornography (i.e., pornography containing deviant content) was a risk factor for all groups. The importance of conceptualizing particular risk factors (e.g., pornography), within the context of other individual characteristics is discussed.
