Error monitoring is related to processing internal affective states

Detecting behavioral errors is critical for optimizing performance. Here, we tested whether error monitoring is enhanced in emotional task contexts, and whether this enhancement depends on processing internal affective states. Event-related potentials were recorded in individuals with low and high levels of alexithymia—that is, individuals with difficulties identifying and describing their feelings. We administered a face word Stroop paradigm (Egner, Etkin, Gale, & Hirsch, 2008) in which the task was to classify emotional faces either with respect to their expression (happy or fearful; emotional task set) or with respect to their gender (female or male; neutral task set). The error-related negativity, a marker of rapid error monitoring, was enhanced in individuals with low alexithymia when they adopted the emotional task set. By contrast, individuals with high alexithymia did not show such an enhancement. Moreover, in the high-alexithymia group, the difference in the error-related negativities between the emotional and neutral task sets correlated negatively with difficulties identifying their own feelings, as measured by the Toronto Alexithymia Scale. These results show that error-monitoring activity is stronger in emotional task contexts and that this enhancement depends on processing internal affective states.

Cinematic depiction of conflicts of interest in romantic relationships

Conflicts of interest resulting from a romantic relationship, just like conflicts of interest of a financial nature, have the potential to negatively affect professional decisions. For this reason, many companies, universities, and government agencies have policies designed to prevent conflicts of interest at the expense of personal liberties. In addition, the feminist literature in the last two decades has added the specter of sexual harassment to the evaluation of conflicts, of interest. A few academic authors have voiced opposition to this state of affairs. In an effort to enrich the debate with viewpoints from outside of academia, I analyze six popularly acclaimed motion pictures that address the issue of conflicts of interest in romantic relationships. All six films convey the idea that people are aware of potential complications but regularly avoid these complications. This suggests that restrictive policies on conflicts of interest may not be justified.     

Focusing attention on overlapping and non-overlapping figures with subjective contours

In a series of five experiments we investigated whether observers could focus attention on a restricted visual area that was demarcated by Kanizsa-like subjective contours, and whether this effect also occurred in the case of overlapping figures. The task was a simple reaction time to a luminance increment and the basic finding was that reaction time was faster when the imperative stimulus fell inside the focus of attention than when it fell outside. The first two experiments showed that the extent of the attentional focus could be adapted to a region that was demarcated by subjective contours, thus extending the results of previous studies that used regions demarcated by real contours. The last three experiments showed that, regardless of the type of margins, focusing was more efficient for the figure that was perceived as lying in front in a pair of overlapping figures.

Visual encoding of patterns is subject to dual-task interference

Two stimuli were presented at varying stimulus onset asynchronies (SOAs), with each stimulus associated with a distinct task. The first stimulus was a tone at one of either two or three frequencies. In two conditions, the task associated with a tone was either a speeded two-alternative discrimination (2AD), or a speeded three-alternative discrimination (3AD) based on the pitch of the tone. In a third condition, subjects were told to ignore the tone. The second stimulus was a briefly exposed study matrix of red and black squares followed by a mask. After a fixed delay, the mask was replaced by a test matrix that was either the same or different from the study matrix. The task associated with the matrices was to indicate, with no speed pressure, whether the study matrix and the test matrix were the same or different. Results from each speeded AD condition showed that subject's accuracy in the matrix task decreased as the SOA between the tone and the study matrix decreased. This effect was larger for the 3AD tone task than with a 2AD tone task. In addition, within each speeded AD condition, longer RTs in the tone task were associated with lower accuracy in the matrix task. None of these effects was evident when the subjects were told to ignore the tone. These results suggest that encoding visual information can be subject to significant capacity limitations imposed by cross-modal multitasking.     

Friendships of older men and women: exchange patterns and satisfaction

In this study we examined the relation between perceived equity of exchanges and friendship satisfaction for a sample of 110 older men and women. Respondents were interviewed concerning their relationship with their best friend and one other friend in their support network. Perceived equity was a significant predictor of friendship satisfaction only in the case of the other friend. In addition, results showed that men were involved in more equitable friendships than were women. Discussion focuses on the importance of equity consideration and gender differences in the friendships of older adults.
