Abstract. Although attention control accounts for a unique portion of the variance in working memory capacity (WMC), the way in which attention control contributes to WMC has not been thoroughly specified. The current work focused on fractionating attention control into distinctly different executive processes and examined to what extent key processes of attention control including updating, shifting, and prepotent response inhibition were related to WMC and whether these relations were different. A number of 216 university students completed experimental tasks of attention control and two measures of WMC. Latent variable analyses were employed for separating and modeling each process and their effects on WMC. The results showed that both the accuracy of updating and shifting were substantially related to WMC while the link from the accuracy of inhibition to WMC was insignificant; on the other hand, only the speed of shifting had a moderate effect on WMC while neither the speed of updating nor the speed of inhibition showed significant effect on WMC. The results suggest that these key processes of attention control exhibit differential effects on individual differences in WMC. The approach that combined experimental manipulations and statistical modeling constitutes a promising way of investigating cognitive processes.

Abstract. Despite the substantial attention paid to stress management in the extant coping literature, media use has been surprisingly overlooked as a strategy worthy of close examination. Although media scholars have suggested media use may be driven by a need to relax, related research has been sporadic and, until recently, disconnected from the larger conversation about stress management. The present research aimed to determine the relative value of media use within the broader range of coping strategies. Based on surveys of both students and breast cancer patients, media use emerged as one of the most frequently selected strategies for managing stress across a range of personality and individual difference variables. Further, heavier television consumers and those with higher perceived stress were also more likely to use media for coping purposes. Finally, those who choose media for stress management reported it to be an effective tool, although perhaps not as effective as other popular strategies. This research not only documents the centrality of media use in the corpus of stress management techniques, thus highlighting the value of academic inquiry into media-based coping, but it also offers evidence supporting the positive role media use can play in promoting psychological well-being.
