Comparing negative emotion differentiation in young and older individuals: A picture-based study

Life span theories suggest that emotional experiences become more complex (i.e., nuanced and differentiated) with age. Theoretically, the cause of this increased complexity has been proposed to be age-related changes in life contexts such as goals and daily stressors. Consequently, age may not affect emotional complexity in settings where the influence of age-specific life contexts is reduced. However, this hypothesis has yet to be explored. In the present study, we investigated one aspect of emotional complexity, namely emotion differentiation. Extending previous research, we assessed age-group differences in negative emotion differentiation between young and older adults in a controlled experimental setting. A sample of 114 young and 132 older adults rated their emotional response to 34 negative pictures according to intensity of four negative emotions. Based on these ratings, two indicators of emotion differentiation were calculated. The results revealed no significant age-group differences in negative emotion differentiation. The findings indicate stability in negative emotion differentiation with increasing age when the influence of life context is reduced. The findings are consistent with life span theories suggesting that developmental changes in emotional complexity occur largely as a result of age-related changes in life contexts rather than more stable age-related changes in individual characteristics.

The Behavioral Immune System Shapes Partisan Preferences in Modern Democracies: Disgust Sensitivity Predicts Voting for Socially Conservative Parties

While there is growing interest in the relationship between pathogen-avoidance motivations and partisanship, the extant findings remain contradictory and suffer from a number of methodological limitations related to measurement and internal and external validity. We address these limitations and marshal the most complete test to date of the relationship between the behavioral immune system and partisanship, as indexed by which party people identify with and vote for. Using a unique research design, including multiple well-powered, nationally representative samples from the United States and Denmark collected in election and nonelection contexts, our study is the first to establish in cross-national data a consistent, substantial, and replicable connection between deep-seated pathogen-avoidance motivations and socially conservative party preferences across multiple validated measures of individual differences in disgust sensitivity and using large representative samples. We explore the relative contribution of the pathogen-avoidance model and sexual strategies for accounting for this relationship.     

IS FORGETTING REPREHENSIBLE? Holocaust Remembrance and the Task of Oblivion

“Forgetting” plays an important role in the lives of individuals and communities. Although a few Holocaust scholars have begun to take forgetting more seriously in relation to the task of remembering—in popular parlance as well as in academic discourse on the Holocaust—forgetting is usually perceived as a negative force. In the decades following 1945, the terms remembering and forgetting have often been used antithetically, with the communities of victims insisting on the duty to remember and a society of perpetrators desiring to forget. Thus, the discourse on Holocaust memory has become entrenched on this issue. This essay counters the swift rejection of forgetting and its labeling as a reprehensible act. It calls attention to two issues: first, it offers a critical argument for different forms of forgetting; second, it concludes with suggestions of how deliberate performative practices of forgetting might benefit communities affected by a genocidal past. Is it possible to conceive of forgetting not as the ugly twin of remembering but as its necessary companion?     

Anterior cingulate cortex and cognitive control: Neuropsychological and electrophysiological findings in two patients with lesions to dorsomedial prefrontal cortex

Whereas neuroimaging studies of healthy subjects have demonstrated an association between the anterior cingulate cortex (ACC) and cognitive control functions, including response monitoring and error detection, lesion studies are sparse and have produced mixed results. Due to largely normal behavioral test results in two patients with medial prefrontal lesions, a hypothesis has been advanced claiming that the ACC is not involved in cognitive operations. In the current study, two comparably rare patients with unilateral lesions to dorsal medial prefrontal cortex (MPFC) encompassing the ACC were assessed with neuropsychological tests as well as Event-Related Potentials in two experimental paradigms known to engage prefrontal cortex (PFC). These included an auditory Novelty Oddball task and a visual Stop-signal task. Both patients performed normally on the Stroop test but showed reduced performance on tests of learning and memory. Moreover, altered attentional control was reflected in a diminished Novelty P3, whereas the posterior P3b to target stimuli was present in both patients. The error-related negativity, which has been hypothesized to be generated in the ACC, was present in both patients, but alterations of inhibitory behavior were observed. Although interpretative caution is generally called for in single case studies, and the fact that the lesions extended outside the ACC, the findings nevertheless suggest a role for MPFC in cognitive control that is not restricted to error monitoring.
