Mindfulness-based programs,perceived stress and well-being at work: The preferential use of informal practices

IntroductionOrganizations which engage in the promotion of well-being are likely to prevent mental health issues in workers. Mindfulness-based interventions offer new perspectives to increase well-being at work. However, the issue of finding time and framework to practice at work is important. Recent studies suggested that informal mindfulness practices could be useful in reducing stress and increasing well-being.ObjectiveThe present study aimed to study how the duration and type of mindfulness practice may enhance employees’ well-being.MethodA multi-method (qualitative and quantitative), controlled pre/post design study (N = 72) was conducted to collect data about the type of preferred mindfulness practices used during an 8-week MBSR program, and to analyse the effects of the program on employees’ well-being. Number of sessions, number of days of practice, and practice time per day were used as moderators.ResultsParticipants reported a preferential use of brief, informal practices. Employees who followed the MBSR program reported higher levels of well-being compared to the wait-list control group (η² = .194). Those who preferentially used informal practices showed the same increase in well-being as those who reported preferentially using formal practices. The number of days of practice did not moderate the effect of the intervention on well-being.ConclusionBrief and informal mindfulness practices appear to be a promising means of increasing well-being in everyday life. Further research is needed to compare an 8-week mainly informal mindfulness-based program to a classical MBSR program to identify whether informal practices may be sufficient to increasing employees’ well-being.     

Origines et développement des théories d’horloge interne du temps psychologique

The article describes the origins and development of internal clock theory. The history is traced via body temperature studies in the 1920s and 1930s, with input from 19th. century and early 20th. century psychophysics, through to the model of Treisman (1963). This model derived timed behaviour from an interaction of internal clock, memory store, and comparison processes. A successor to Treisman's model was the scalar expectancy theory (SET) of Gibbon and colleagues (1984). The origins of SET in animal Psychology are described, as is its application to human timing (in the early 1990s), in particular recent work on the operation of the internal clock itself. Finally, a discussion of some recent developmental studies of timing illustrates both how internal clock models have been applied, and how modern research may require a reconceptualization of the operation of classical internal clock models.     

Attention et jugement temporel

The role of attention in human’s duration judgment processes is analyzed. Empirical evidences which indicate that a dissociation exists between prospective and retrospective duration judgments are presented. Attention is directly involved in prospective duration judgments processes. Attentional-based models, which can explain prospective duration judgments are presented together with empirical evidences which validate the general attentional model on the levels of both regular cognitive processes and high level executive-control processes. Waiting is presented as a natural situation during which prospective duration judgment processes are evoked. The attentional model is used for explaining why a duration spent waiting seems to pass slowly, in contrast to a situation to which one is interested in a book or a movie and in which time flies fast.     

Le développement des capacités de jugement des durées chez l'enfant

For several decades, since the work of Piaget, it has been believed that correct judgements of durations require sophisticated reasoning abilities that emerge at about 8 years of age. However, some researchers have demonstrated accurate temporal knowledge in young children and have explained their poor judgements on classical piagetian tasks not by their inability to correctly judge time, but by age-related attentional difficulties. Recently, researchers have thus reassessed the temporal behaviour in children with the experimental paradigms used in animals and humans adults in the framework of the temporal information processing models that assume the existence of an internal clock. Findings suggest that this type of clock is functional at an early age. Other findings allow us to better understand the role of the development of attention, memory and metacognitive processes in the development of the abilities to judge time. The aim of this article is to synthesize these recent findings.     

Un modèle neurobiologique de la perception et de l'estimation du temps

Frontal-striatal circuits provide an important neurobiological substrate for timing and time perception as well as for working memory. In this review, we outline recent theoretical and empirical work to suggest that interval timing and working memory rely not only on the same anatomic structures, but also on the same neural representation of a specific stimulus. In the striatal beat-frequency model, cortical neurons fire in an oscillatory fashion to form representations of stimuli, and striatal medium spiny neurons detect those patterns of cortical firing that occur co-incident to important temporal events. Information about stimulus identity can be extracted from the specific cortical networks that are involved in the representation, and information about duration can be extracted from the relative phase of neural firing. The properties derived from these neurobiological models fit well with the psychophysics of timing and time perception as well as with information-processing models that emphasize the importance of temporal coding in a variety of working-memory phenomena.     

Le geste approprié au juste moment : faut-il une horloge pour que le mouvement soit dans les temps ?

The movement of a body is defined as a variation of its position in time (dx/dt). However, referring to time to describe a movement does not imply that the production of a biological movement necessitates an explicit control of the temporal parameters, and even less that such a control has to be performed with the help of a clock. In this review of the literature, we will try to show, through an analysis of the protocols used, that the answer to this question critically depends on the motor task to be performed. Possible directions towards a convergence will be proposed.     

The chameleon effect,the temporal aspects of mimicry and their impact on service measurement

BackgroundIn an experiment conducted in a natural setting, we test the link between mimicry, the amount of time during which the mimicry behavior takes place, and its impact on service quality.MethodsCable TV clients (n = 120) were randomly assigned to six experimental conditions (2 mimicry conditions: verbal mimicry vs. no mimicry x 3 interaction time: 5 vs. 10 vs. 15 minutes). Perceived service quality served as the dependent measurement.ResultsA main effect of mimicry was found on service quality: a cable TV representative was perceived more favorably when he mimicked the customer. Importantly, it was shown that even small portions of mimicry are beneficial, meaning that practitioners do not have to mimic someone for a long time to achieve benefits.ConclusionThe paper shows new benefits for the mimicker: more positive judgments by the mimickee regarding the impact on several different levels of service quality.
