The influence of future time perspective on work engagement and job performance: the role of job crafting

This two-wave study aimed to examine future time perspective (FTP) as an antecedent of job crafting, and in turn job crafting as a mediator in associations between FTP and work outcomes. Based on the lifespan socio-emotional selectivity theory, we expected that open-ended and limited FTP would evoke different forms of job crafting, which in turn would be associated with changes in work engagement and job performance. In line with our expectations, we found that employees whose open-ended FTP increased over a 1-year time period also crafted more job resources and challenging job demands such that their job provided them with more opportunities for knowledge acquisition, which in turn resulted in increased levels of work engagement and job performance. However, contrary to our expectations, employees whose limited FTP increased over the 1-year time period did not proactively reduce their hindering job demands. Hence, although crafting fewer hindering job demands was directly related to decreased levels of work outcomes as expected, we found no indirect effect of changes in limited FTP on changes in work engagement and performance via changes in this job crafting behaviour. These findings have important implications for the literature on job crafting and FTP.     

Effects of deprivation on engagement in preferred activities by persons with developmental disabilities

This study examined the effects of deprivation on engagement in activities for 3 adult men with developmental disabilities. First, an assessment was conducted to identify a high- and a low-preference activity for each participant. Second, the high-preference activity was made available following three amounts of deprivation of the activity (15 min, 2 hr, and 1 to 4 days); the low-preference activity was made available following the schedule of deprivation that produced the highest level of engagement by each participant in the high-preference activity. The results were that 1 to 4 days of deprivation produced the highest average amounts of engagement in the high-preference activity for each participant; this amount of deprivation did not produce high engagement in the low-preference activities. Third, the deprivation procedures and results were replicated when high-preference activities were presented by teachers during the participants' daily activities when their engagement had been quite low.     

Interacting effects of age and time of day on verbal fluency performance and intraindividual variability

We explored the effects of age and time of day (TOD) on verbal fluency ability with respect to performance level and intraindividual variability (IIV). Verbal fluency, which involves complex cognitive operations, was examined in 20 older (mean age = 72.8 years) and 20 younger (mean age = 24.2 years) adults with test start time alternating between morning and evening across four days. Older adults generated more words in the morning and younger adults more in the evening, corresponding with self-report peak TOD. Age by TOD interactions were also observed across fluency tasks on the number of switches among subcategory exemplars during word generation and on the IIV observed in switching behavior. Older adults exhibited greater variability in switching in the evening than in the morning, whereas younger adults showed the opposite pattern. These findings demonstrate that processes involving energization (initiating and sustaining) and attentional control may be particularly sensitive to age differences in TOD influences on cognition.     

Different perspectives on measuring lifestyle engagement: a comparison of activity measures and their relation with cognitive performance in older adults

Given the limitations associated with assessing activity engagement via the frequency of specific activities, it may be valuable to consider the characteristics of an activity. The method of asking individuals to report the amount of time spent engaging in activities that have certain characteristics was compared to a specific activity questionnaire, and a daily diary regarding their relation to cognitive functioning. Participants 60–90 years old (n = 187) completed the activity measurement methods and a series of cognitive tasks. Structural equation models showed that all three activity methods were predictive of adults’ cognitive performance, but no measure predicted all outcomes. Each activity measure provided unique information. Notably, the combination of the measurement types predicted more variance than any of the measures alone. There is additional power to predict cognition when multiple activity measurement methods are used, and daily assessment can be a valuable tool to augment traditional specific activity questionnaires.     

Evaluating the predictive validity of a single stimulus engagement preference assessment.

Most preference assessments require individuals to choose among two or more stimuli. More recently, the duration of engagement with items has been used as an index of preference. In the current study, the predictive validity of a single stimulus engagement (SSE) preference assessment was evaluated with 4 individuals. Stimuli were presented singly for a brief period while engagement with that stimulus was recorded. Although SSE preference rankings closely matched paired stimulus preference assessment rankings for only 2 of the 4 participants, relative preference rankings based on duration of engagement predicted relative reinforcer effectiveness for all participants in a subsequent concurrent‐schedule reinforcer assessment. The SSE procedure took less time to administer than the paired stimulus procedure but produced less stable preference rankings across administrations. The SSE procedure may be appropriate for individuals who have difficulty selecting one stimulus from among two or more stimuli, and it may be well suited for evaluating activities that are difficult to present in a paired stimulus format.     

Work engagement: Further reflections on the state of play

In this article we further reflect on the “state of play” of work engagement. We consider, clarify, and respond to issues and themes raised by eight preeminent work engagement researchers who were invited to respond to our position article. The key themes we reflect upon include: (1) theory and measurement of engagement; (2) state and task engagement; (3) climate for engagement versus collective engagement; (4) the dark side of engagement; (5) where job crafting may go wrong; and (6) moderators of the engagement–performance relationship. We conclude that engagement can sensibly be conceptualized as a positive and high arousal affective state characterized by energy and involvement; that there may be additional dimensions that might usefully be included; that we need to more fully understand the day-to-day and moment-to-moment temporal dynamics and implications of engagement; that a “climate for engagement” will influence individual and organizational outcomes; that although engagement is at heart a positive construct, the “dark side” of engagement needs to be acknowledged and understood; that “job crafting” provides a potentially powerful way for employees to manage their engagement; and that we need to gain a better understanding of the moderators that influence the way that engagement is related to performance. We also outline some practical implications that follow from our conclusions.     

The moderating effect of passion on the relation between activity engagement and positive affect

The present diary study investigates the moderating effect of passion on the relation between activity engagement and daily positive affect. In line with past research (Vallerand et al. 2003, Journal of Personality and Social Psychology, 85, 756) it is suggested that people with an obsessive passion have more difficulties putting their passion aside to invest themselves in other activities, to a point where they fail to experience positive affect during these activities. A sample of 154 college students reported their daily activity engagement and positive affect over a 2-week period. HLM analyses show that the more people have an obsessive passion the more they experience accentuated decreases in positive affect during days when they do not engage in their passion compared to days when they do. In contrast, harmonious passion predicts daily positive affect on days when people engage in their activity. These results are discussed in light of previous research on passion and positive affect.

Perceptual and motor components of performance in three different reaction time experiments

Three reaction time experiments were conducted to examine the effects of time of day, stimulus intensity, stimulus modality, and constant and variable foreperiod on the perceptual and motor components of performance. These variables are all supposed to generate changes in arousal level. All the independent variables affected the perceptual component, while the motor component was significantly influenced only by foreperiod and modality. The results are discussed in relation to aspects of dependency/independency of the perceptual and motor components of human performance in reaction time experiments.     

Preference for leisure items over edible items in individuals with dementia: A replication

We replicated previous research in which adults with dementia tended to show a preference for leisure items over edible items when presented in the same array. Additionally, we conducted engagement analyses with the highest, middle, and lowest preference leisure items to determine whether relative preference corresponded to engagement in the natural environment. The most highly preferred stimulus for 6 out of 7 participants was a leisure item, and for each of those six the top 3 preferred stimuli were leisure stimuli. For 4 participants, the most preferred stimulus also produced the longest duration of engagement. We discuss the issues we encountered when conducting preference assessments with adults with intact vocal verbal repertoires, and suggest potential explanations for the displacement of edibles by leisure stimuli in older adults with dementia.     

Individual differences in the influence of time of day on executive functions

Previous research has documented the impact of time of day on vigilance and memory and the moderating influence of circadian typology (morningness-eveningness) on the relationship between time of testing and cognitive processes. This study examined the impact of circadian typology and time of testing on executive functions. Morning-type and evening-type people were randomly assigned to a morning or afternoon testing time, and their performance on neuropsychological tests, including the Conners Continuous Performance Test (CPT), the Digit Span test, the Controlled Oral Word Association Test (COWAT), and the Wisconsin Card Sorting Test (WCST) was compared. No interactions between circadian typology and time of day were observed on the CPT or Digit Span test. A time of day effect was found on the letter generation portion of the COWAT. More words were generated in the afternoon than in the morning. In contrast, performance on the WCST was best when morning-type participants were tested at their optimal time of day. These findings suggest that circadian typology should be considered when scheduling neuropsychological assessments, rehabilitation training, and critical job tasks.

Dynamics of psychological contracts with work engagement and turnover intention: The influence of organizational tenure

This study investigated the interrelations of the psychological contract with work engagement and turnover intention, which has hitherto been a largely overlooked topic in psychological contract research. Although previous research has mainly focused on how psychological contracts influence job attitudes and behaviours, it is proposed here that attitudes and behaviours also affect the psychological contract that the employee has with the organization. Moreover, it is proposed that because reciprocity norms are more important among shortly tenured employees, mutual relationships between psychological contracts and work engagement and turnover intention were stronger for employees with lower organizational tenure. Longitudinal data were collected among 240 employees and proposed models were evaluated with structural equation modelling. The results show that indeed psychological contract fulfilment was longitudinally related to higher work engagement and lower turnover intentions, but only for employees with low tenure. Moreover, stability in work engagement, turnover intention, and psychological contract over time was higher for those with high tenure, whereas the relations between turnover intention and the psychological contract were stronger for those with low organizational tenure. These findings demonstrate that psychological contracts are reciprocally interrelated with work outcomes, and that such relations are stronger for those with low tenure.     

Time‐of‐day variation of visuo‐spatial attention

Time‐of‐day variation of visuo‐spatial attention in relation to body temperature and subjective arousal was assessed. At five different times of day, alertness, covert, and overt orienting of attention were assessed in fifteen healthy subjects. Based on previous studies reporting a tight coupling of alerting and orienting the present study investigates potential attentional asymmetries induced by diurnal variations of arousal. Both covert and overt orienting of attention improved in the course of the day. However, no asymmetries between left and right visual hemifields could be detected. Covert orienting additionally covaried with body temperature, indicating a quite close relation between the attentional arousal and orienting system. Conversely, overt orienting only improved due to repeated testing but did not correlate with body temperature suggesting a partial independence of both modes of attentional orienting. It can be assumed that due to limited diurnal variations of arousal in the participants and practice effects caused by repeated testing, no attentional asymmetries could be provoked.     

Distinct performance profiles on the Brixton test in frontotemporal dementia

The Brixton Spatial Anticipation Test is a well-established test of executive function that evaluates the capacity to abstract, follow, and switch rules. There has been remarkably little systematic analysis of Brixton test performance in the prototypical neurodegenerative disorder of the frontal lobes: behavioural variant frontotemporal dementia (bvFTD) or evaluation of the test’s ability to distinguish frontal from temporal lobe degenerative disease. We carried out a quantitative and qualitative analysis of Brixton performance in 76 patients with bvFTD and 34 with semantic dementia (SD) associated with temporal lobe degeneration. The groups were matched for demographic variables and illness duration. The bvFTD group performed significantly more poorly (U = 348, p < .0001, r = .58), 53% of patients scoring in the poor–impaired range compared with 6% of SD patients. Whereas bvFTD patients showed problems in rule acquisition and switching, SD patients did not, despite their impaired conceptual knowledge. Error analysis revealed more frequent perseverative errors in bvFTD, particularly responses unconnected to the stimulus, as well as random responses. Stimulus-bound errors were rare. Within the bvFTD group, there was variation in performance profile, which could not be explained by demographic, neurological, or genetic factors. The findings demonstrate sensitivity and specificity of the Brixton test in identifying frontal lobe degenerative disease and highlight the clinical value of qualitative analysis of test performance. From a theoretical perspective, the findings provide evidence that semantic knowledge and the capacity to acquire rules are dissociable. Moreover, they exemplify the separable functional contributions to executive performance.     

Modelling the influence of time pressure on reaction time of drivers

Speeding is a major traffic violation and time pressure is one of the leading contributors to speeding. High-speed driving requires an immediate response to perilous events from the driver to avoid a crash. Reaction time is one of the important driving performance measures to assess the driver’s response to the event. Therefore, the current study examined the influence of time pressure on reaction times of the drivers measured for two different perilous events (pedestrians crossing and obstacle overtaking). Eighty-five Indian licensed drivers participated in a driving simulation study designed for three different time pressure conditions: No Time Pressure (NTP), Low Time Pressure (LTP), and High Time Pressure (HTP). The survival analysis technique was used to model the effect of time pressure and driver characteristics with reaction times of the drivers. It was observed that drivers’ reaction times decreased by 18% and 9% in LTP and 28% and 16% in HTP during the pedestrians crossing and obstacle overtaking events, respectively. Further, 1 m/second increase in approach speed resulted in 2% and 4% reduction in reaction times of the drivers in pedestrians crossing and obstacle overtaking events, respectively. Young drivers responded 21% faster than mature drivers during the pedestrians crossing event. Interestingly, sleeping hours and physical fitness played an important role in driver’s reaction to the events. The drivers performing regular physical exercise and having minimum eight-hours of overnight sleep reacted 16% and 17% earlier in pedestrians crossing and obstacle overtaking events, respectively. The overall findings from this study showed enhanced stimulus-response behaviour of the drivers under time pressure driving conditions. The results obtained from the study can give new insight into various safety-related ITS applications.
