Shedding Light on the Adverse Spillover Effects of Work-Family Conflict on Unethical Sales Behaviors at Work: A Daily Diary Study

Despite the antecedents of unethical sales behavior (USB) have been well studied, these literatures primarily focus on the work domain and neglect the spillover effects of the home domain. Drawing on ego depletion theory as an overarching theoretical framework, this research investigates why and how salespersons' work-family conflict (WFC) at home triggers next day's USB at work. This study used daily diary data collected from 99 salespeople in two weeks to test the proposed hypotheses. The multilevel path analysis indicates that evening's WFC positively affects next afternoon's USB via increased next morning's ego depletion (ED). Furthermore, service climate was found to moderate this indirect relationship, such that the indirect relationship becomes weaker under high service climate. To the best of my knowledge, this study is one of the first to reveal that salespersons' daily WFC may serve as a role conflict event and lead to next day's USB at work, which provides a fine-grained understanding of spillover effects of daily WFC through a daily diary study.

Differential neural responding to affective stimuli in 6- to 8-year old children at high familial risk for depression: Associations with behavioral reward seeking

OBJECTIVE

Children of depressed parents are at increased risk for psychopathology. One putative mechanism of risk appears to be altered processing of emotion-related stimuli. Although prior work has evaluated how adolescent offspring of depressed parents may show blunted reward processing compared to low-risk youth, there has been less attention to how young children with this familial history may differ from their peers during middle childhood, a period of critical socio-affective development METHOD: The current study evaluated 56 emotionally healthy 6-to 8-year children who were deemed at high-risk (n = 25) or low-risk (n = 31) for depression based on maternal history of depression. Children completed a behavioral reward seeking task in the laboratory and an fMRI paradigm assessing neural response to happy faces, a social reward.

RESULTS

Findings demonstrated that high-risk children showed blunted responding to happy faces in the dorsal striatum compared to low-risk children. Further, lower responding in the dorsal striatum and dorsolateral prefrontal cortex was related to lower behavioral reward seeking, but only in high-risk children.

CONCLUSION

Function within neural reward regions may be altered in high-risk offspring as young as 6- to 8-years of age. Further, neural reward responding may be linked to lower behavioral response to obtain reward in these high-risk offspring.
