The Mind

Undergraduates ( N = 274) participated in a weeklong daily-life experience-sampling study of mind wandering after being assessed in the lab for executive-control abilities (working memory capacity; attention-restraint ability; attention-constraint ability; and propensity for task-unrelated thoughts, or TUTs) and personality traits. Eight times a day, electronic devices prompted subjects to report on their current thoughts and context. Working memory capacity and attention abilities predicted subjects’ TUT rates in the lab, but predicted the frequency of daily-life mind wandering only as a function of subjects’ momentary attempts to concentrate. This pattern replicates prior daily-life findings but conflicts with laboratory findings. Results for personality factors also revealed different associations in the lab and daily life: Only neuroticism predicted TUT rate in the lab, but only openness predicted mind-wandering rate in daily life (both predicted the content of daily-life mind wandering). Cognitive and personality factors also predicted dimensions of everyday thought other than mind wandering, such as subjective judgments of controllability of thought. Mind wandering in people’s daily environments and TUTs during controlled and artificial laboratory tasks have different correlates (and perhaps causes). Thus, mind-wandering theories based solely on lab phenomena may be incomplete.

Unwanted imaginations of future fears can, to some extent, be avoided. This is achieved by control mechanisms similar to those engaged to intentionally forget unwanted memories. Intentional forgetting relies on the executive control network, whose functioning is impaired after exposure to acute stress. This study investigates whether acute stress affects the ability to intentionally control future fears and, furthermore, whether individual differences in executive control predict a susceptibility to these effects. The study ran over two consecutive days. On day 1, the working memory capacity of one hundred participants was assessed. Thereafter, participants provided descriptions and details of fearful episodes that they imagined might happen in their future. On day 2, participants were exposed to either the stress or no-stress version of the Maastricht Acute Stress Test, after which participants performed the Imagine/No-Imagine task. Here, participants repeatedly imagined some future fears and suppressed imaginings of others. Results demonstrated that, in unstressed participants, suppression successfully induced forgetting of the episodes’ details compared to a baseline condition. However, the observed reduction in anxiety toward these events remained unchanged. Acute stress was found to selectively impair intentional forgetting and, further, this effect was moderated by working memory capacity. Specifically, low working memory predicted a susceptibility to these detrimental effects. These findings provide novel insights into conditions under which our capacity to actively control future fears is reduced, which may have considerable implications for understanding stress-related psychopathologies and symptomatologies characterized by unwanted apprehensive thoughts.

Study Results

Abstract In complex tasks such as interpreting, the importance of a well-functioning working memory can hardly be overestimated. However, empirical studies have failed to produce consistent results with regard to an interpreter advantage in working memory. Recent studies tend to focus on the executive component of working memory. To our knowledge, no such study has compared the possible cognitive advantage of aspiring interpreters relative to other multilinguals before training takes place, in spite of the fact that excellent cognitive abilities are considered important in many interpreter selection procedures. In this study, we compared the working memory capacity and executive functions of a group of 20 student interpreters with two other groups of advanced language users who were all at the start of their Master’s training. Data were collected on three executive control functions: inhibition, shifting and updating. A forward and a backward digit span task for measuring the participants’ working memory capacity was also included in this study. Results revealed only negligible differences between the three groups at onset of training. The presumed cognitive advantage of aspiring interpreters with regard to executive control was not found.
