Developmental Differences in the Ability to Provide Temporal Information About Repeated Events

Children (n = 372) aged 4–8 years participated in one or four occurrences of a similar event and were interviewed 1 week later. Compared with 85% of children who participated once, less than 25% with repeated experience gave the exact number of times they participated, although all knew they participated more than once. Children with repeated experience were asked additional temporal questions, and there were clear developmental differences. Older children were more able than younger children to judge relative order and temporal position of the four occurrences. They also demonstrated improved temporal memory for the first and last relative to the middle occurrences, while younger children did so only for the first. This is the first systematic demonstration of children's memory for temporal information after a repeated event. We discuss implications for theories of temporal memory development and the practical implications of asking children to provide temporal information. Copyright © 2015 John Wiley & Sons, Ltd.     

Recalling Positive Events at Work Makes Employees Feel Happier,Move More,but Interact Less: A 6-Week Randomized Controlled Intervention at a Japanese Workplace

Simple self-administered activities, such as practicing gratitude or kindness, have been shown to increase happiness, yet only self-report measures have been used so far. Our study, conducted with a Japanese workplace sample, incorporated a novel technology to gather precise behavioral data reflecting participant movement and social interactions. Employees were randomly assigned to either recount three positive events at work (a positive activity) or list work tasks they completed (control) weekly for 6 weeks; furthermore, they reported their happiness levels and wore sociometric badges that recorded their behavior. Relative to controls, participants who considered good things at work not only reported relatively greater happiness over time but moved more upon arriving to work, engaged in less social interaction, and left the office earlier. Most of the findings were moderated by participant effort, such that those who put more effort into the positive activity also showed greater changes.     

Measuring Spiritual Needs in a Secular Society: Validation and Clinimetric Properties of the Danish 20-Item Spiritual Needs Questionnaire

Journal of Religion and Health - In secular cultures, such as Denmark, tools to measure spiritual needs are warranted to guide existential and spiritual care. We examined the clinimetric properties...     

Bayesian PTSD-Trajectory Analysis with Informed Priors Based on a Systematic Literature Search and Expert Elicitation

There is a recent increase in interest of Bayesian analysis. However, little effort has been made thus far to directly incorporate background knowledge via the prior distribution into the analyses. This process might be especially useful in the context of latent growth mixture modeling when one or more of the latent groups are expected to be relatively small due to what we refer to as limited data. We argue that the use of Bayesian statistics has great advantages in limited data situations, but only if background knowledge can be incorporated into the analysis via prior distributions. We highlight these advantages through a data set including patients with burn injuries and analyze trajectories of posttraumatic stress symptoms using the Bayesian framework following the steps of the WAMBS-checklist. In the included example, we illustrate how to obtain background information using previous literature based on a systematic literature search and by using expert knowledge. Finally, we show how to translate this knowledge into prior distributions and we illustrate the importance of conducting a prior sensitivity analysis. Although our example is from the trauma field, the techniques we illustrate can be applied to any field.     

Online Module for Carrier Screening in Ashkenazi Jewish Individuals Compared with In-Person Genetics Education: A Randomized Controlled Trial

To increase accessibility to genetics services for low-urgency patients seeking Ashkenazi Jewish (AJ) carrier screening, we designed an interactive computer (IC) module that provides pre-test genetics education and allows genetics professionals to order the test without meeting the patients beforehand. We compared this module with in-person genetic counseling (GC) using a randomized trial. AJ individuals were randomized to undergo genetics education via the IC module (n = 26) or GC (n = 28). We compared post-interventional genetics knowledge, perceived genetic risk, and anxiety between the two groups, after accounting for pre-interventional scores, using ANCOVA. Wilcoxon Rank-Sum test was used to compare post-interventional satisfaction. Post-interventional genetics knowledge, risk perception, or anxiety were not significantly different between the two groups after accounting for baseline scores (p = 0.50–0.54), although the data are inconclusive regarding the module’s non-inferiority at a 5% margin. Post-intervention satisfaction scores were generally higher in the GC group than the IC module group. Our IC module has the potential to improve access to clinical genetics services for patients and staff, but it is not suitable for all AJ patients and cannot completely replace the benefits of in-person consultations.     

Cross-modal validation of the Leipzig Affective Norms for German (LANG)

Affective stimuli are increasingly used in emotion research. Typically, stimuli are selected from databases providing affective norms. The validity of these norms is a critical factor with regard to the applicability of the stimuli for emotion research. We therefore probed the validity of the Leipzig Affective Norms for German (LANG) by correlating valence and arousal ratings across different sensory modalities. A sample of 120 words was selected from the LANG database, and auditory recordings of these words were obtained from two professional actors. The auditory stimuli were then rated again for valence and arousal. This cross-modal validation approach yielded very high correlations between auditory and visual ratings (>.95). These data confirm the strong validity of the Leipzig Affective Norms for German and encourage their use in emotion research.     

Keep Changing Your Beliefs, Aiming for the Truth

We investigate the process of truth-seeking by iterated belief revision with higher-level doxastic information. We elaborate further on the main results in Baltag and Smets (Proceedings of TARK, 2009a, Proceedings of WOLLIC’09 LNAI 5514, 2009b), applying them to the issue of convergence to truth. We study the conditions under which the belief revision induced by a series of truthful iterated upgrades eventually stabilizes on true beliefs. We give two different conditions ensuring that beliefs converge to “full” (complete) truth, as well as a condition ensuring only that they converge to true (but not necessarily complete) beliefs.     

The primacy of perceiving: emotion recognition buffers negative effects of emotional labor

There is ample empirical evidence for negative effects of emotional labor (surface acting and deep acting) on workers' well-being. This study analyzed to what extent workers' ability to recognize others' emotions may buffer these effects. In a 4-week study with 85 nurses and police officers, emotion recognition moderated the relationship between emotional labor and work engagement: Workers with high emotion recognition engaging in emotional labor did not report lower work engagement after 4 weeks, whereas those with low emotion recognition did. These effects pertained to both surface and deep acting. The results suggest that emotional labor be not necessarily detrimental to workers' engagement. Instead, the impact of emotional labor hinges upon workers' ability to correctly identify interaction partners' emotions.
