Age slowing down in detection and visual discrimination under varying presentation times

The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine age‐related changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an ex‐Gaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher, and they also showed a higher distribution average except for the lower and higher presentation time. The results suggest a general slowdown in both tasks for age under different presentation times, except for the cases where presentation times were lower and higher. Moreover, if these parameters are understood to be a reflection of executive functions, these findings are consistent with the common view that age‐related cognitive deficits show a decline in this function.     

Seeing the big picture: Broadening attention relieves sadness and depressed mood

We examined whether the broadened attentional scope would affect people's sad or depressed mood with two experiments, enlightened by the meaning of “seeing the big picture” and the broaden‐and‐build model. Experiment 1 (n = 164) is a laboratory‐based experiment, in which we manipulated the attentional scope by showing participants zoomed‐out or zoomed‐in scenes. In Experiment 2 (n = 44), we studied how depressed mood and positive and negative emotions were affected when participants watched distant versus proximal scenes for eight weeks in real life. Healthy participants in Experiment 1, who were induced to feel sad, could return to the baseline mood after having the broadened attention task but not after having the narrowed attention task, which indicated that immediate attention broadening manipulation could function as antidotes for the lingering effects of induced negative emotions. Participants with depressed mood in Experiment 2 showed reduced depressed mood, increased positive affect, and decreased negative affect after receiving attention broadening training compared to those receiving attention narrowing training. Our findings suggest a robust role of broadened attentional scope in relieving negative emotions and even mildly depressed mood in the long run.     

“To‐be‐forgotten” statements become less true: Memory processes involved in selection and forgetting lead to truthfulness changes of ambiguous sentences

What happens when people try to forget something? What are the consequences of instructing people to intentionally forget a sentence? Recent studies employing the item‐method directed forgetting paradigm have shown that to‐be‐forgotten (TBF) items are, in a subsequent task, emotionally devaluated relative to to‐be‐remembered (TBR) items, an aftereffect of memory selection (Vivas, Marful, Panagiotidou & Bajo, 2016). As such, distractor devaluation by attentional selection generalizes to memory selection. In this study, we use the item‐method directed forgetting paradigm to test the effects of memory selection and inhibition on truth judgments of ambiguous sentences. We expected the relative standing of an item in the task (i.e., whether it was instructed to be remembered or forgotten) to affect the truthfulness value of that item, making TBF items less valid/truthful than TBR items. As predicted, ambiguous sentences associated with a “Forget” cue were subsequently judged as less true than sentences associated with a “Remember” cue, suggesting that instructions to intentionally forget a statement can produce changes in the validity/truthfulness of that statement. To our knowledge, this is the first study to show an influence of memory processes involved in selection and forgetting on the perceived truthfulness of sentences.     

When criticism is ineffective: The case of historical trauma and unsupportive allies

Three studies examined the effect of historical trauma reminders and criticism from international allies on attitudes toward current conflicts. In Study 1, Israeli participants (N = 116) were primed with the Holocaust, and read either that the U.S. President Obama supports Israel's right to defend itself and attack Iran, or that he opposes such action. Then, support for preemptive violence was assessed. Study 2 (N = 133) replicated this design, comparing inclusive and exclusive framings of the Holocaust. Study 3 (N = 478), examined the effect of Holocaust reminders and criticism from the European Union on attitudes toward militant policies against Palestinians. All three studies found that Holocaust primes juxtaposed with international criticism increased support for aggression, especially under exclusive framings of the Holocaust. Study 3, however, found this effect only among left‐wing participants. These findings indicate that when historical trauma is salient, international criticism may be ineffective and may even backfire.     

Differences in alexithymia and emotional awareness in exhaustion syndrome and chronic fatigue syndrome

Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS. This cross‐sectional study compared self‐reported alexithymia and observer‐rated emotional awareness in patients with ES (n = 31), CFS (n = 38) and healthy controls (HC) (n = 30). Self‐reported alexithymia was measured with the Toronto Alexithymia Scale‐20 (TAS‐20) and emotional awareness with an observer‐rated performance test, the Level of Emotional Awareness Scale (LEAS). Additionally, depression and anxiety were scored by the Hospital Anxiety and Depression Scale (HADS). Results show that patients with ES expressed higher self‐reported alexithymia in the TAS‐20 compared to HC, but had similar emotional awareness capacity in the observer‐rated performance test, the LEAS. Patients with CFS expressed more difficulties in identifying emotions compared to HCs, and performed significantly worse in the LEAS‐total and spent more time completing the LEAS as compared to HC. Correlation and multiple regressions analyses revealed that depression and anxiety positively correlated with and explained part of the variances in alexithymia scores, while age and group explained the major part of the variance in LEAS. Findings of this study indicate that emotional status is different in patients with ES and CFS with respect to both self‐reported alexithymia and observer‐rated emotional awareness. Emotional parameters should be approached both in clinical investigation and psychotherapy for patients with ES and CFS.     

Subjective Social Standing and Conflict Tactics Among Young Kenyan Men

Efforts to reduce intimate partner violence in sub‐Saharan Africa generally approach the issue through the lens of women's empowerment. These efforts include foci on women's relative power in the relationship, educational background, and earning potential. The social status of men has largely been ignored, reducing the potential to involve them in efforts to demote intimate partner violence. In this study we consider whether a man's perceived social status predicts conflict tactics, and whether these tactics are mediated by loneliness and collective self‐esteem from a community‐based sample in semi‐rural Kenya (n = 263). We find that men who reported lower perceived social status also reported significantly more frequent violent conflicts with their intimate partners. This association was significantly, and completely, mediated by lower collective self‐esteem and higher loneliness. There was no direct association between subjective social status and negotiation‐based conflict tactics, although there was an indirect association. Men with higher perceived social status reported higher collective self‐esteem, and men with higher collective self‐esteem reported more negotiation‐based conflict tactics. These findings inform efforts to reduce intimate partner violence by involving men, showing potential to reduce violence by building self‐esteem among men—particularly those with lower perceived social status.     

Interfaith Groups as Mediating Structures for Political Action: A Multilevel Analysis

This study investigates interfaith groups from across the United States to understand how these religious settings may serve as mediating structures to facilitate individual political action. Based on a multilevel modeling analysis with 169 individuals from 25 interfaith groups, we found that core activities of the group, such as group members sharing community information (e.g., announcing upcoming events, political meetings, community issues) or sharing religious information (e.g., educating members about their religion) positively and negatively predicted individual political action as a result of group participation, respectively. Moreover, a sense that the interfaith group served as a community to work for local change, but not trust within the group, predicted political action as a result of group participation. However, this effect for a sense the group served as a community to work for local change was stronger and more positive as the degree of community information sharing in the group increased. These results show that a core activity of sharing community information may enhance the ability of a group to mediate political action. Overall, these findings demonstrate the potential role of interfaith groups to mediate political action, and show the importance of considering both individual and group characteristics when understanding these religious settings. Limitations and directions for future research are also discussed.
