Lost or fond? Effects of nostalgia on sad mood recovery vary by attachment insecurity.

Nostalgia involves a fond recollection of people and events lost to time. Growing evidence indicates that nostalgia may ameliorate negative affective states such as loneliness and boredom. However, the effect of nostalgia on sadness is unknown, and there is little research on how social connectedness might impact nostalgia's effects. Grounded in a theoretical framework whereby people with lower levels of attachment insecurity benefit more from nostalgia, we exposed participants to a mortality-related sad mood and then randomly assigned them to reflect on a nostalgic or an ordinary event memory. We examined changes in mood and electrodermal activity (EDA) and found that nostalgic versus ordinary event memories led to a blunted recovery from sad mood, but that this effect was moderated by degree of attachment insecurity, such that participants with low insecurity benefited from nostalgia whereas people with high insecurity did not. These findings suggest that nostalgia's benefits may be tied to the degree of confidence one has in one's social relationships.

Uninstructed emotion regulation choice in four studies of cognitive reappraisal.

In emotion regulation (ER) research, participants are often trained to use specific strategies in response to emotionally evocative stimuli. Yet theoretical models suggest that people vary significantly in strategy use in everyday life. Which specific strategies people choose to use, and how many, may partially depend on contextual factors like the emotional intensity of the situation. It is thus possible - even likely - that participants spontaneously use uninstructed ER strategies in the laboratory, and that these uninstructed choices may depend on contextual factors like emotional intensity. We report data from four studies in which participants were instructed to use cognitive reappraisal to regulate their emotions in response to pictures, the emotional intensity of which varied across studies. After the picture trials, participants described which and how many strategies they used by way of open-ended responses. Results indicated that while a substantial proportion of participants in all studies described strategies consistent with cognitive reappraisal, a substantial proportion also endorsed uninstructed strategies. Importantly, they did so more often in the context of studies in which they viewed higher-intensity pictures. These findings underscore the importance of considering uninstructed ER choice in instructed paradigms and situational context in all studies of ER.

Emotion reactivity and regulation are associated with psychological functioning following the 2011 earthquake, tsunami, and nuclear crisis in Japan.

Frequent and successful use of cognitive reappraisal, an emotion regulation strategy that involves rethinking the meaning of an emotional event in order to change one's emotional response, has been linked in everyday life to positive outcomes such as higher well-being. Whether we should expect this association to be maintained in a strong, temporally and spatially close emotional context is an unexplored question that might have important implications for our understanding of emotion regulation and its relations to psychological functioning. In this study of members of the U. S. Embassy Tokyo community in the months following the March 2011 earthquake, tsunami, and nuclear crisis in Japan, self-reported use of cognitive reappraisal was not related to psychological functioning, but demonstrated success using cognitive reappraisal to decrease feelings of unpleasantness in response to disaster-related pictures on a performance-based task was associated with fewer symptoms of depression and posttraumatic stress. Moreover, emotional reactivity to these pictures was associated with greater symptomatology. These results suggest that situational intensity may be an important moderator of reappraisal and psychological functioning relationships.

Mood-induced shifts in attentional bias to emotional information predict ill- and well-being.

Previous research has suggested that biased attention toward emotional (typically threatening) stimuli contributes to ill-being (e.g., high levels of anxiety), but its contribution to well-being is less clear. The researchers assessed naturalistic shifts in attentional bias toward threatening and pleasant schematic face cues in response to five induced mood states in college students. They also assessed state anxiety and satisfaction with life concurrently and 3 weeks later. Controlling for concurrent anxiety, a fear-induced shift in attention to threatening cues was associated with increased levels of later anxiety. Controlling for concurrent life satisfaction, a happiness-induced shift in attention to emotional cues (both threatening and pleasant) was associated with increased levels of later life satisfaction. These results suggest that mood-induced changes in deployment of attention to emotional information may accumulate in ways that impact psychological functioning, yet these effects depend on mood state and the emotional cues afforded by the context.

Psychiatric and emotional sequelae of surgical amputation.

The prevalence of posttraumatic stress symptoms after the experience of amputation is not well established. The current study gathered data on the prevalence of posttraumatic stress disorder (PTSD) and other psychiatric disorders after amputation. Participants were recruited from a large Northeastern rehabilitation hospital and were assessed with structured clinical interviews. The data suggest that planned surgical amputations resulting from chronic illness do not frequently lead to PTSD symptoms. In contrast, data suggest that amputation resulting from accidental injury may lead to a higher prevalence of PTSD, in part because of the emotional stress surrounding the accident.

A functional magnetic resonance imaging study of amygdala and medial prefrontal cortex responses to overtly presented fearful faces in posttraumatic stress disorder.

BACKGROUND: Previous functional neuroimaging studies have demonstrated exaggerated amygdala responses and diminished medial prefrontal cortex responses during the symptomatic state in posttraumatic stress disorder (PTSD). OBJECTIVES: To determine whether these abnormalities also occur in response to overtly presented affective stimuli unrelated to trauma; to examine the functional relationship between the amygdala and medial prefrontal cortex and their relationship to PTSD symptom severity in response to these stimuli; and to determine whether responsivity of these regions habituates normally across repeated stimulus presentations in PTSD. DESIGN: Case-control study. SETTING: Academic medical center. PARTICIPANTS: Volunteer sample of 13 men with PTSD (PTSD group) and 13 trauma-exposed men without PTSD (control group). MAIN OUTCOME MEASURES: We used functional magnetic resonance imaging (fMRI) to study blood oxygenation level-dependent signal during the presentation of emotional facial expressions. RESULTS: The PTSD group exhibited exaggerated amygdala responses and diminished medial prefrontal cortex responses to fearful vs happy facial expressions. In addition, in the PTSD group, blood oxygenation level-dependent signal changes in the amygdala were negatively correlated with signal changes in the medial prefrontal cortex, and symptom severity was negatively related to blood oxygenation level-dependent signal changes in the medial prefrontal cortex. Finally, relative to the control group, the PTSD group tended to exhibit diminished habituation of fearful vs happy responses in the right amygdala across functional runs, although this effect did not exceed our a priori statistical threshold. CONCLUSIONS: These results provide evidence for exaggerated amygdala responsivity, diminished medial prefrontal cortex responsivity, and a reciprocal relationship between these 2 regions during passive viewing of overtly presented affective stimuli unrelated to trauma in PTSD.
