An evaluation of the cross‐national generalizability of organizational commitment

Using data from two large multinational samples, this research sought to contribute to our knowledge of international organizational behaviour by examining the cross‐national generalizability of organizational commitment. Sample 1 included employees of 10 subsidiaries of a large multinational organization, whereas Sample 2 relied on data collected in 25 nations in the context of a large opinion survey. Results in both samples supported the expectation that measures of commitment would be more susceptible to measurement non‐equivalence than measures of job satisfaction. Differences in relationships between commitment and satisfaction across countries were observed in both samples, as were differences in mean commitment levels. Nation‐level individualism/collectivism (I/C) failed to account for the observed differences, however, suggesting that commitment and I/C are largely independent, despite theoretical arguments to the contrary. Results of the study suggest that despite some cross‐national variation, differences in commitment across national boundaries are small and empirically unrelated to I/C.     

High impact running improves learning

Regular physical exercise improves cognitive functions and lowers the risk for age-related cognitive decline. Since little is known about the nature and the timing of the underlying mechanisms, we probed whether exercise also has immediate beneficial effects on cognition. Learning performance was assessed directly after high impact anaerobic sprints, low impact aerobic running, or a period of rest in 27 healthy subjects in a randomized cross-over design. Dependent variables comprised learning speed as well as immediate (1 week) and long-term (>8 months) overall success in acquiring a novel vocabulary. Peripheral levels of brain-derived neurotrophic factor (BDNF) and catecholamines (dopamine, epinephrine, norepinephrine) were assessed prior to and after the interventions as well as after learning. We found that vocabulary learning was 20 percent faster after intense physical exercise as compared to the other two conditions. This condition also elicited the strongest increases in BDNF and catecholamine levels. More sustained BDNF levels during learning after intense exercise were related to better short-term learning success, whereas absolute dopamine and epinephrine levels were related to better intermediate (dopamine) and long-term (epinephrine) retentions of the novel vocabulary. Thus, BDNF and two of the catecholamines seem to be mediators by which physical exercise improves learning.     

Is word perception in a second language more vulnerable than in one's native language? Evidence from brain potentials in a dual task setting

We assessed the effect of additional tasks on language perception in second-language and native speakers. The N400 component of the event-related potential was recorded to spoken nouns that had to be judged for synonymity with a preceding word, while additional choice responses were required to visual stimuli. In both participant groups N400 was delayed as a function of temporal overlap with the additional task. In second-language speakers there was a global delay of N400 independent of additional task load and a decrease of accuracy at highest overlap. These findings are interpreted within a single channel account of language perception.     

Electrophysiological correlates of prosody and punctuation

Psycholinguistic models of sentence parsing are primarily based on reading rather than auditory processing data. Moreover, both prosodic information and its potential orthographic equivalent, i.e., punctuation, have been largely ignored until recently. The unavailability of experimental online methods is one likely reason for this neglect. Here I give an overview of six event-related brain potential (ERP) studies demonstrating that the processing of both prosodic boundaries in natural speech and commas during silent reading can determine syntax parsing immediately. In ERPs, speech boundaries and commas reliably elicit a similar online brain response, termed the Closure Positive Shift (CPS). This finding points to a common mechanism, suggesting that commas serve as visual triggers for covert phonological phrasing. Alternative CPS accounts are tested and the relationship between the CPS and other ERP components, including the P600/SPS, is addressed.     

Serious delinquent behavior,sensation seeking,and electrodermal arousal

Low tonic skin conductance level (SCL) has been related, inconsistently, to both delinquency and sensation-seeking. This study tests the hypothesis that there is an interaction such that high sensation seeking delinquents, in particular, have low SCLs. Participants consisted of 335 boys from the Pittsburgh Youth Study classified as serious delinquents or controls based upon 10 years of prospectively collected self-report delinquency data. Participants' skin conductance was evaluated at age 16 along with several personality and neuropsychological measures. Both delinquency and sensation seeking were characterized by low SCL. However, there was no evidence to suggest that the presence of both of these factors together lead to especially low skin conductance levels. This finding is not explained by differences between the groups on measures of negative emotionality, IQ, socioeconomic status, or impulsivity.     

Descartes and the Labyrinth of the World

In the Rules the young Descartes likens his method to the thread that guided Theseus. The simile is born of a confidence that he has seen through the art of the followers of Daedalus and this has given him a model of how to unriddle the labyrinth of the world. From the very beginning Descartes had an interest not only in optics, perspective, and painting, but in using his knowledge of them to duplicate some of the effects said to have been created by the thaumaturgic magicians. Anamorphoses and automata not only provided Descartes with examples of deceptive appearance, but also pointed the way to the solution of the riddle they posed. Yet it is precisely the attempt to take this exit from the labyrinth of the world that threatens to lead back into it, as the search for truth is threatened by the infinity of space. To claim absolute truth, the natural philosopher would have to show that the mechanical model he has proposed is the only one that could account for the phenomena in question. This, as Descartes himself is forced to recognize, he is unable to do. Are we back in the labyrinth? Instead of seeing in Descartes's method an Ariadne's thread, Father Bourdin likens that method to Icarus. Annoyed, Descartes ridicules the good Father. But Bourdin's too often empty rhetoric raises a serious question: is Descartes Theseus, Daedalus, or Icarus? At stake is our understanding of the world we live in.     

Review and Discussion of Strategies to Address Low Trainer‐to‐Staff Ratios

Researchers have developed an array of highly adaptable intervention packages with well‐documented efficacy for staff and teacher training. As indicated by Parsons, Rollyson, and Reid (2012) in their article on best practices in staff training, behavior analysts must use methods that are both effective and efficient given the limited resources of many human service settings (e.g., low trainer‐to‐staff ratios). The purpose of this paper is to summarize research on practical innovations for staff and teacher training, including the use of video‐based technology and self‐instruction materials that may help trainers to operate effectively despite limited time and personnel. Results are discussed in terms of the current state of the evidence for each practical innovation and considerations for integrating these strategies with best practices in staff training.

Effects of Personalized Versus Generic Implementation of an Intra-Organizational Online Survey on Psychological Anonymity and Response Behavior: A Field Experiment

Purpose

In the present study, we sought to investigate the effects of online survey implementation strategies on perceived anonymity and employee response behavior in organizational surveys.

Design/Methodology/Approach

A field experiment was conducted to compare two commonly used online survey implementation strategies (N = 815). One group of employees received a personalized invitation to the survey and a log-in password, while the other group received a general invitation and did not have to provide a password.

Findings

The results showed that the applied implementation strategies had no substantial effects on perceived anonymity. Moreover, there were no significant effects on nonresponse or the responses of survey participants to closed-ended and open-ended survey questions.

Implications

The present study supposes that online surveys are not a uniform phenomenon and that differences in the implementation of online surveys need to be considered. However, the findings indicate that the use of specified-personalized implementation strategies does not necessarily lead to a substantial decrease in perceived anonymity or automatically result in reduced data quality. Thus, in many cases, the investigated online survey implementation strategies are unlikely to cause serious reductions in perceptions of anonymity and quality of responses to organizational online surveys.

Originality/Value

In spite of the frequent use of online surveys in organizations, little is known about the consequences of online implementation strategies for perceptions of anonymity and response behavior. This study is one of the few empirical examinations of the psychological consequences of different online implementation strategies frequently used in organizational surveying.     

Globally surveying in English: Investigation of the measurement equivalence of a job satisfaction measure across bilingual and native English speakers

The present research investigated measurement equivalence of organizational attitude surveys across bilingual and native English respondents. Results largely supported the equivalence of the measure of job satisfaction when administered in English to bilingual and native English‐speaking respondents.
