“…Results indicated a main effect of the version [F(1.133) = 36.31, p < 0.001], demonstrating that the emotional version stimulates more arousal (M = 1.81; SD = 1.14) than the non-emotional version (M = 0.80, SD = 0.72), which is consistent with previous studies 18,28,29 . In addition, we observed an effect of the presence of SAD [F(1.133) = 5.52, p < 0.05], which was responsible for a more intense evaluation of the effect of the stories' emotional arousal (M = 1.58, SD = 1.06) in comparison to the participants without SAD (M = 1.22, SD = 1.11), which is consistent with typical aspects of this disorder, in which individuals often become hypervigilant regarding their physiological alterations and their bodily sensations, which seems to interfere in how participants with SAD rated the material 30 .…”

Background: False memories are memories of events that never occurred or that occurred, but not exactly as we recall. Events with emotional content are subject to false memories production similar to neutral events. However, individual differences, such as the level of maladjustment and emotional instability characteristics of Social Anxiety Disorder (SAD), may interfere in the production of false memories. Objectives: This study aimed to assess the effect of emotion in memory performance for an event witnessed by participants with and without SAD. Methods: Participants were 61 young adults with SAD and 76 without any symptoms of SAD who were randomly assigned to watch a story with or without emotional arousal. Participants answered a subjective scale of emotion about the story and a recognition memory test. Results: Participants with SAD recovered more true memories and more false memories for the nonemotional version compared to the emotional version of the story. Overall, participants with SAD produced fewer false memories compared to those without SAD. Discussion: This finding suggests that social anxiety may have a significant impact on emotional memory accuracy, which may assist in the development and improvement of techniques for therapeutic intervention.

“…fMRI findings indicate stronger activation to arousing erotic pictures in males compared to females, but an opposite pattern for mutilations (Sabatinelli et al, 2004). Larger positive potentials in the 250-700 ms range have been found in females compared to males for arousing pictures with unpleasant affect (Gasbarri et al, 2006). Not all studies find gender effects, but systematic assessment of gender could prove fruitful in characterizing stimulus-and task factors (Cahill, 2004;Rozenkrants and Polich, 2007).…”

The review summarizes and integrates findings from 40 years of event-related potential (ERP) studies using pictures that differ in valence (unpleasant-to-pleasant) and arousal (low-to-high) and that are used to elicit emotional processing. Affective stimulus factors primarily modulate ERP component amplitude, with little change in peak latency observed. Arousal effects are consistently obtained, and generally occur at longer latencies. Valence effects are inconsistently reported at several latency ranges, including very early components. Some affective ERP modulations vary with recording methodology, stimulus factors, as well as task-relevance and emotional state. Affective ERPs have been linked theoretically to attention orientation for unpleasant pictures at earlier components (<300 ms). Enhanced stimulus processing has been associated with memory encoding for arousing pictures of assumed intrinsic motivational relevance, with task-induced differences contributing to emotional reactivity at later components (>300 ms). Theoretical issues, stimulus factors, task demands, and individual differences are discussed.

“…Armony and Sergerie (2007) extended these results by demonstrating that not only the sex of the observer but also the sex of the stimulus face plays a role in this lateralized processing: while the left amygdala was more engaged in memory for fearful female faces in women, right amygdala activation was associated with successful remembered male faces in men. Using EEG, Gasbarri et al (2006Gasbarri et al ( , 2007 could show a significant sex by hemisphere interaction with a female-left and male-right direction in the P300 evoked by either emotionally arousing pictures or stories. The findings described above were further enhanced by a study by Kilpatrick et al (2006), providing evidence for the corresponding sex difference in functional connectivity during resting conditions.…”
