PurposeWork-related use of information and communication technologies (ICTs) after hours can be potentially detrimental to employee well-being. In the current study, we examine whether psychological detachment mediates the link between work-related use of ICTs after hours and fatigue and whether affective commitment exacerbates this mediated relationship.Design/methodology/approachWe collected two waves of data from 295 employees in Vietnam, with 51% being female and an average age of 37.81 years old (SD = 7.93).FindingsWork-related use of ICTs after hours was positively related to employees' fatigue via psychological detachment. The negative relationship between work-related use of ICTs after hours and psychological detachment was stronger for employees with higher affective commitment.Practical implicationsOrganizations are encouraged to set policies and procedures to reduce work-related use of ICTs after hours to protect employee health; when work-related use of ICTs after hours is necessary, organizations should provide employees, especially those with higher affective commitment, with resources and strategies to better detach from this experience.Originality/valueOur findings contribute to the understanding of how work-related use of ICTs after hours might adversely affect employee well-being through psychological detachment and that more committed employees can be more affected in this process.

Food choice plays a vital role in people’s lives and well‐being, and this topic has received more research attention in recent years. The aims of the present research were to identify subgroups of participants who shared similar profiles of multiple motives for food choices, and examine differences across motive types on the well‐being of young and middle‐aged Chinese adults. Participants were 627 Chinese adults aged 18–58 years who completed questionnaire measures. The results of Latent Profile Analysis showed that based on the configurations among different motives for food choice, there were five profiles of food choice motives, corresponding to five types of Chinese adult consumers: unconcerned, mood oriented, weight control oriented, food enthusiast and health oriented. The food enthusiast consumers were more likely to include young adults with high‐income level and educational level, while the unconcerned consumers had a larger share of middle‐aged adults with low income. Results of ANOVA suggested that the types of food choice motives significantly predicted individuals’ well‐being. Specifically, the food enthusiast group had the highest level of well‐being, while the unconcerned group had the lowest level of well‐being. The other three groups had moderate levels of well‐being. The current study is the first to explore the potential influence of food choice motives on well‐being using a person‐centred approach, and the results have practical implications for public health authorities in developing effective interventions, for food companies in tailoring marketing campaigns and for individuals in optimizing food choices.

Switch costs are generally found in language switching tasks. However, the locus where switch costs occur during bilingual language production remains unclear. Several studies that used a cued language-switching paradigm have attempted to investigate this question in bilingual language production, but researchers have not reached a consensus. Moreover, we are interested in where switch costs occur when language selection occurs after lemma activation. Previous studies have not investigated this question because most previous studies presented language cues before or along with the stimuli. Therefore, we used a modified cued language-switching paradigm with a combined event-related potentials (ERPs) technique to explore the locus of switch costs during bilingual language production. The cue and stimulus were separated and presented in two different presentation sequences in which Indonesian–Chinese bilingual speakers were instructed to name digits in their L1 or L2 according to the color of the cue. The ERPs related to the cue and stimulus for two presentation sequences were measured. In the stimulus-cue sequence, the analysis that was time-locked to cues revealed a reversed switch cost as early as 220 ms after the cue onset; furthermore, a switch cost was shown in L1 with a late stage post-cue onset. The results suggested that when language selection occurred after lemma activation, the switch costs mainly occurred at the lemma selection stage. In the cue-stimulus sequence, the analysis that was time-locked to cues did not reveal significant main effects of switching, whereas the analysis that was time-locked to digits yielded a switch cost, again indicating that switch costs mainly occurred at the lemma selection stage rather than at the language task schema competition stage. Overall, our results indicated that when bilinguals spoke digits aloud in the language switching task, switch costs mainly occurred at the lemma selection stage.
