The Role of a Model's Age for Young Children's Imitation: A Research Review

The influence of a model's age on young children's behaviour has been a subject of considerable debate among developmental theorists. Despite the recent surge of interest, controversy remains about the nature of peer influence in early life. This article reviews studies that investigated the influence of a model's age on young children's behaviour in the first 5 years of life, and presents an account of seemingly mixed results. We propose that children imitate familiar behaviour for social reasons, such as in order to identify with the model or to communicate likeness. Since age is an important indicator of the degree of being alike, we propose that children are more likely to imitate familiar behaviour from peers. In contrast, we propose that children primarily imitate novel behaviour for learning reasons. Since adults are perceived as being more competent than children, children are more likely to learn from adults. We further suggest that increased peer experience leads children to evaluate peers as valuable resources for learning novel behaviour in domains in which peers are knowledgeable.

Norms of valence, arousal, dominance, and age of acquisition for 4,300 Dutch words

This article presents norms of valence/pleasantness, activity/arousal, power/dominance, and age of acquisition for 4,300 Dutch words, mainly nouns, adjectives, adverbs, and verbs. The norms are based on ratings with a 7-point Likert scale by independent groups of students from two Belgian (Ghent and Leuven) and two Dutch (Rotterdam and Leiden-Amsterdam) samples. For each variable, we obtained high split-half reliabilities within each sample and high correlations between samples. In addition, the valence ratings of a previous, more limited study (Hermans & De Houwer, Psychologica Belgica, 34:115-139, 1994) correlated highly with those of the present study. Therefore, the new norms are a valuable source of information for affective research in the Dutch language.     

Side effects of gender‐fair language: How feminine job titles influence the evaluation of female applicants

In many languages, feminization has been used as a strategy to make language more gender‐fair, because masculine terms, even in a generic function, exhibit a male bias. Up to date, little is known about possible side effects of this language use, for example, in personnel selection. In three studies, conducted in Polish, we analyzed how a female applicant was evaluated in a recruitment process, depending on whether she was introduced with a feminine or masculine job title. To avoid influences from existing occupations and terms, we used fictitious job titles in Studies 1 and 2: diarolo?ka (feminine) and diarolog (masculine). In Study 3, we referred to existing occupations that varied in gender stereotypicality. In all studies, female applicants with a feminine job title were evaluated less favorably than both a male applicant (Study 1) and a female applicant with a masculine job title (Studies 1, 2, and 3). This effect was independent of the gender stereotypicality of the occupation (Study 3). Participants' political attitudes, however, moderated the effect: Conservatives devaluated female applicants with a feminine title more than liberals (Studies 2 and 3).

A Perception-Action Coupling Type of Control in Long Jumping

The authors' goal was to identify the control mechanisms used by long jumpers (N = 6) to precisely position their foot at the board. In addition to the intertrial method usually used in previous research, an original method based on a trial-by-trial analysis was also implemented. If the approach to the board in long jumping encompasses two distinct sequences separated by a key step that marks the initiation of visual control, then a trial-by-trial analysis should reveal those sequences, regardless of the amount of adjustment: The step number at which regulation is initiated should be the same irrespective of the amount of adjustment. If, in contrast, a perception-action coupling mechanism operates, then the step number at which regulation is initiated should be a function of the amount of adjustment: A linear relation between those 2 variables should emerge. The results of the present study are compatible with continuous control mechanisms based on a perception-action coupling.     

A multiple case study approach to work stress prevention in Europe

Work stress has become a major issue among European employees. The current practice of its prevention seems disappointing, as work stress prevention programmes are predominantly reactive and biased to the individual. The lack of organization-level intervention studies is a barrier to progress in reducing work-related stress. In addition to the “true experimental approach”, multiple case studies may provide an adequate research strategy for addressing the potential impact of stress interventions in organizations. The study aim was to obtain more knowledge with respect to evidence-based work stress prevention in Europe, by focusing on both content (cause-effect relationships) and process (“how”). Therefore it was decided: (1) to collect from each European Union member state a work stress intervention study; (2) to analyse each of these cases as to content and process factors; and (3) to systematically compare these studies in a step-by-step approach. Through a network approach, 11 cases were identified. Nine projects received an acceptable methodological standard and were included in this study. Evaluation of these cases reveals that stress prevention is no “one time event”, nor merely a technical process. It is concluded that “true prevention” (i.e., preventive measures that are based on an adequate diagnosis identifying risk factors and risk groups, which theoretically and logically fit in with the problems, and which are introduced and implemented in a proper way) may be beneficial to both the employee and the organization.     

Taking personal initiative and communicating about ideas: What is important for the creative process and for idea creativity?

Using multisource data, this study focused on the process aspect of creativity at work. A modification of Amabile's (1988 Amabile, T. M. 1988. “A model of creativity and innovation in organizations”. In Research in organizational behavior, Edited by: Staw, B. M. and Cummings, L. L. Vol. 10, 123–167. Greenwich, CT: JAI Press.  [Google Scholar]) stage model of the creative process with the stages of problem identification, preparation, idea generation, and idea validation served as the basis for our study. We examined personal initiative and idea-related communication as two important factors for the creative process and for the degree of creativity of one specific idea an employee recently produced at work. In a sample of 52 nurses, we found that idea-related communication was positively related to engagement in the creative process but not to idea creativity. Personal initiative boosted engagement in the beginning of the creative process and was positively related to creativity as an outcome. Results suggest that idea-related communication is important for showing engagement in the creative process, whereas personal initiative is important in the beginning of the creative process and for idea creativity.     

Vacation (after-) effects on employee health and well-being, and the role of vacation activities, experiences and sleep

Most vacations seem to have strong, but rather short-lived effects on health and well-being (H&W). However, the recovery-potential of relatively long vacations and the underlying processes have been disregarded. Therefore, our study focused on vacations longer than 14 days and on the psychological processes associated with such a long respite from work. In the present study, we investigated (1) how health and well-being (H&W) develop during and after a long summer vacation, (2) whether changes in H&W during and after vacation relate to vacation activities and experiences and (3) whether changes in H&W during and after vacation relate to sleep. Fifty-four employees reported their H&W before, three or four times during and five times after vacation. Vacations lasted 23 days on average. Information on vacation experiences, work-related activities and sleep was collected during vacation. Vacation activities were assessed immediately after vacation. H&W increased quickly during vacation, peaked on the eighth vacation day and had rapidly returned to baseline level within the first week of work resumption. Vacation duration and most vacation activities were only weakly associated with H&W changes during and after vacation. Engagement in passive activities, savoring, pleasure derived from activities, relaxation, control and sleep showed strong relations with improved H&W during and to a lesser degree after vacation. In conclusion, H&W improved during long summer vacations, but this positive effect was short-lived. Vacation experiences, especially pleasure, relaxation, savoring and control, seem to be especially important for the strength and persistence of vacation (after-) effects.     

Stripping the Boss: The Powerful Role of Humor in the Egyptian Revolution 2011

The Egyptian Revolution 2011 has shaken the Arab world and stirred up Middle-East politics. Moreover, it caused a rush in political science and the neighboring disciplines, which had not predicted an event like this and now have troubles explaining it. While many things can be learned from the popular uprising, and from the limitations of previous scholarship, our focus will be on a moral resource, which has occasionally been noticed, but not sufficiently explored: the role of humor in keeping up the spirit of the Revolution. For 18 days, protestors persevered at Liberation Square in Central Cairo, the epicenter of resistance; at times a few dozens, at times hundreds of thousands. What they did was to fight the terror of the regime, which reached absurd peaks during those days, with humor—successfully. We offer a social-functionalist account of the uprising, which includes behavioral as well as cultural levels of analysis, and illuminates how humorous means helped to achieve deadly serious goals. By reconstructing how Egyptians laughed themselves into democracy, we outline a social psychology of resistance, which uses humor both as a sword and a shield.     

Does irrelevant music cause an irrelevant sound effect for auditory items?

The irrelevant sound effect (ISE) describes the significant reduction in verbal serial recall during irrelevant sounds with distinct temporal-spectral variations (changing-state sound). Whereas the ISE is well-documented for the serial recall of visual items accompanied by irrelevant speech and nonspeech sounds, an ISE caused by nonspeech sounds has not been reported for auditory items. Closing this empirical gap, Experiment 1 (n=90) verified that instrumental staccato-music reduces auditory serial recall compared to legato-music and silence. Its detrimental impact was not due to perceptual masking, disturbed encoding, or increased listening effort, as the employed experimental design and methods ensured. The found nonspeech ISE in auditory serial recall is corroborated by Experiment 1b (n=60), which, by using the same experimental design and methods, replicated the well-known ISE during irrelevant changing-state speech compared to steady-state speech, pink noise, and silence.     

How does a vacation from work affect employee health and well-being?

Health and well-being (H&W) improve during vacation. However, it is unclear whether this general development applies to all employees, while also little is known about the underlying processes causing such an improvement. Our research questions were: (1) Does every worker experience a positive effect of vacation on H&W? and (2) Can vacation activities and experiences explain changes in H&W during vacation? In a 7-week longitudinal field study, 96 workers reported their H&W 2 weeks before, during, 1 week, 2 and 4 weeks after a winter sports vacation on 6 indicators (health status, mood, fatigue, tension, energy level and satisfaction). Sixty percent of the sample experienced substantial improvement of H&W during and after vacation. Yet, a small group experienced no (23%) or a negative effect of vacation (17%). Spending limited time on passive activities, pleasure derived from vacation activities, and the absence of negative incidents during vacation explained 38% of the variance in the vacation effect. Although vacation has a positive, longer lasting effect for many, it is not invariably positive for all employees. Choosing especially pleasant vacation activities and avoiding negative incidents as well as passive activities during active vacations apparently contributes to the positive effect of vacation on H&W.
