Don’t believe everything you hear: Routine validation of audiovisual information in children and adults

Previous research has shown that the validation of incoming information during language comprehension is a fast, efficient, and routine process (epistemic monitoring). Previous research on this topic has focused on epistemic monitoring during reading. The present study extended this research by investigating epistemic monitoring of audiovisual information. In a Stroop-like paradigm, participants (Experiment 1: adults; Experiment 2: 10-year-old children) responded to the probe words correct and false by keypress after the presentation of auditory assertions that could be either true or false with respect to concurrently presented pictures. Results provide evidence for routine validation of audiovisual information. Moreover, the results show a stronger and more stable interference effect for children compared with adults.     

Altered behavioral and neural responsiveness to counterfactual gains in the elderly

Counterfactual information processing refers to the consideration of events that did not occur in comparison to those actually experienced, in order to determine optimal actions, and can be formulated as computational learning signals, referred to as fictive prediction errors. Decision making and the neural circuitry for counterfactual processing are altered in healthy elderly adults. This experiment investigated age differences in neural systems for decision making with knowledge of counterfactual outcomes. Two groups of healthy adult participants, young (N = 30; ages 19–30 years) and elderly (N = 19; ages 65–80 years), were scanned with fMRI during 240 trials of a strategic sequential investment task in which a particular strategy of differentially weighting counterfactual gains and losses during valuation is associated with more optimal performance. Elderly participants earned significantly less than young adults, differently weighted counterfactual consequences and exploited task knowledge, and exhibited altered activity in a fronto-striatal circuit while making choices, compared to young adults. The degree to which task knowledge was exploited was positively correlated with modulation of neural activity by expected value in the vmPFC for young adults, but not in the elderly. These findings demonstrate that elderly participants’ poor task performance may be related to different counterfactual processing.     

Global news – global identity? The relationship between media consumption,perception of identity,and ethnocentrism

In line with the common ingroup identity model, the present research investigated whether factors beyond contact conditions are associated with the emergence of a shared identity perception and outgroup attitudes. Concretely, we reasoned that higher consumption of global news would be positively related to a stronger global identity, which in turn would be negatively correlated with ethnocentrism. In contrast, consumption of local news should be associated with a local identity, which would then be positively related to ethnocentrism. To test these ideas, one cross-sectional (N = 576) and one longitudinal study (N = 410) were carried out at an Austrian university. As hypothesized, global news consumption was associated with a stronger global identity, which then accounted for reduced ethnocentrism. However, only in the cross-sectional study, we found empirical evidence that local news interest is positively correlated with ethnocentrism mediated by local identity.
