The cerebellum plays a role in processing procedural memories, such as how to play the piano.  This delayed effect is consistent with the proposal that emotionally arousing memories are more likely to be converted into a relatively permanent trace, whereas memories for nonarousing events are more vulnerable to disruption. For instance, being in a depressed mood increases the tendency to remember negative events (Drace, 2013). They concluded that the hippocampus is involved in memory, specifically normal recognition memory as well as spatial memory (when the memory tasks are like recall tests) (Clark, Zola, & Squire, 2000). First, let’s look at the role of the amygdala in memory formation. As predicted by the researchers, suppressors showed significantly worse performance on a memory test for the orally presented information. That is, suppressors were more likely to report thinking about their behavior and the need to control it during a conversation. Memory formed through autobiographical elaboration is enhanced as compared to items processed for meaning, but not in relation to the self.. The activity of emotionally enhanced memory retention can be linked to human evolution; during early development, responsive behavior to environmental events would have progressed as a process of trial and error. The dimension of valence ranges from highly positive to highly negative, whereas the dimension of arousal ranges from calming or soothing to exciting or agitating. Autobiographical elaboration is known to benefit memory by creating links between the processed stimuli, and the self, for example, deciding whether a word would describe the personal self. However, since Lashley’s research, other scientists have been able to look more closely at the brain and memory. 1. Where were you when you first heard about the 9/11 terrorist attacks? __ A. thalamus __ B. hypothalamus __ C. amygdala __ D. a and b Rationale: p.510 7. However, there is a much more benign explanation: human memory, even flashbulb memories, can be frail. From these studies, it seems the prefrontal cortex is involved. However, Sharot and Phelps (2004) found better recognition of arousing words over neutral words at a delayed test but not at an immediate test, supporting the notion that there is enhanced memory consolidation for arousing stimuli. The … Eric Kandel, for example, spent decades working on the synapse, the basic structure of the brain, and its role in controlling the flow of information through neural circuits needed to store memories (Mayford, Siegelbaum, & Kandel, 2012). The amygdala is involved in fear and fear memories. Another possible explanation for the findings of the emotional arousal delayed effect is post-event processing regarding the cause of the arousal. For example, a word which is seen (in a book) may be stored if it is changed (encoded) into a sound or a meaning (i.e.  According to these theories, different physiological systems, including those involved in the discharge of hormones believed to affect memory consolidation, become active during, and closely following, the occurrence of arousing events. Emotional memory refers to the memories of experiences which evokes or triggers the emotional reaction in higher organisms.  Different explanations have been offered for this effect, according to the different stages of memory formation and reconstruction. These two phenomena, the mood congruity effect and mood-state dependent retrieval, are similar to the context effects which have been traditionally observed in memory research (Baddeley, 1993). The most famous of these was a study by Kleinsmith and Kaplan (1963) that found an advantage for numbers paired with arousing words over those paired with neutral words only at delayed test, but not at immediate test. Lashley did not find evidence of the engram, and the rats were still able to find their way through the maze, regardless of the size or location of the lesion. Describe a flashbulb memory of a significant event in your life. McGaugh, J. L. (1992). The event concluded with the man leaving and the woman phoning a friend. The amygdala is involved in fear and fear memories.  Collaborative recall, as it can be referred to, causes strong emotions to fade. Additional support for the Prioritized processing hypothesis was provided by studies investigating the visual extinction deficit. Laney et al. NY: Oxford University Press, 272-307. One implicit memory system involves cortical areas interacting with the striatum in support of procedural memory, the acquisition of skilled behavior and acquired habits. One could integrate the memorization of information that possesses high emotional significance (highly salient) with information that holds little emotional significance (low salience), prior to a period of sleep. Negative encoding contexts have been correlated to activity in the right amygdala (Lewis & Critchley, 2003). The enhancing effects of emotional arousal on later memory recall tend to be maintained among older adults and the amygdala shows relatively less decline than many other brain regions. Thus, the probability of remembering an event can be enhanced by evoking the emotional state experienced during its initial processing.  Detail recall is also more accurate when someone is experiencing negative emotion; Xie and Zhang (2016) conducted a study in which participants saw a screen with five colors on it and when presented with the next screen were asked which color was missing. "Some characteristics of people's traumatic memories", "Memory enhancement for emotional words: Are emotional words more vividly remembered than neutral words? Emotional memory after evoking the emotional reactions remembers the past experiences based on which the person feels … In January 2002, less than 4 months after the attacks, the then sitting President Bush was asked how he heard about the attacks. C. Strong emotional memories are transferred from short-term memory to long-term memory more quickly than weak emotional memories. It has been argued that emotional memory involves which of the following structures? According to PET scans, there was much more activation in the left inferior prefrontal cortex in the semantic task. While these previous studies focused on how emotion affects memory for emotionally arousing stimuli, in their arousal-biased competition theory, Mather and Sutherland (2011) argue that how arousal influences memory for non-emotional stimuli depends on the priority of those stimuli at the time of the arousal. An interesting issue in the study of the emotion-memory relationship is whether our emotions are influenced by our behavioral reaction to them, and whether this reaction—in the form of expression or suppression of the emotion—might affect what we remember about an event. Through anatomical and functional interactions with other brain regions, the basolateral amygdala (BLA) modulates neurobiological processing leading to increased memory strength. Emotional memory enhancement appears to involve the integration of cognitive and emotional neural networks, in which activation of the amygdala enhances the processing of emotionally arousing stimuli while also modulating enhanced memory consolidation along with other memory-related brain regions, particularly the amygdala, hippocampus, MTL, as well a… The amygdala seems to facilitate encoding memories at a deeper level when the event is emotionally arousing.  Also consistent with this hypothesis are findings of weapon focus effect, in which witnesses to a crime remember the gun or knife in great detail but not other details such as the perpetrator's clothing or vehicle. Researchers have begun to examine whether concealing feelings influences our ability to perform common cognitive tasks, such as forming memories, and found that the emotion regulation efforts do have cognitive consequences. by developing more effective learning strategies. He did this because he was trying to erase the engram, or the original memory trace that the rats had of the maze.  To test this theory, arousal and valence were assessed for over 2,820 words. In a second study, another movie was shown of people arguing. Priority can be determined by bottom-up salience or by top-down goals. Although we don’t yet know which role each neurotransmitter plays in memory, we do know that communication among neurons via neurotransmitters is critical for developing new memories. Also called Affective Memory, this technique asks us to forget about “acting” out emotions. People suffering from this deficit can perceive a single stimulus in either side visual field if it is presented alone but are unaware of the same stimulus in the visual field opposed to the lesional side, if another stimulus is presented simultaneously on the lesional side. Positive encoding contexts have been connected to activity in the right fusiform gyrus. Sleep enhances the consolidation of the high valence and arousing words and therefore these are remembered more post-sleep. One possibility, she says, involves memory. The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex ([link]).  Studies have investigated high valence and arousing words, in comparison to neutral words. (Greenberg, 2004, p. 2). Memory recall tends to be congruent with one's current mood, with depressed people more likely to recall negative events from the past. This part of the cortex is linked to the experience of pain and is responsible for the emotional reaction to the pain rather than the perception of pain. The brain region most strongly implicated in emotional memory is the amygdala. He was searching for evidence of the engram: the group of neurons that serve as the “physical representation of memory” (Josselyn, 2010). Another group of researchers also experimented with rats to learn how the hippocampus functions in memory processing ([link]). The concept of emotional memory and sleep can be applied to real-life situations e.g. Feeling emotion is such a visceral part of the human experience that it is at the same time universal and difficult to fake. The amygdala is involved in fear and fear memories. If an event is being collaboratively recalled the specific detail count is higher than if an individual is doing it. Studies have shown that dividing attention at encoding decreases an individual's ability to utilize controlled encoding processes, such as autobiographical or semantic elaboration. Then, he used the tools available at the time—in this case a soldering iron—to create lesions in the rats’ brains, specifically in the cerebral cortex. In laboratory replications it was found that participants spend a disproportionate amount of time looking at a weapon in a scene, and this looking time is inversely related to the likelihood that individuals will subsequently identify the perpetrator of the crime. However, additional research is needed to confirm whether self-monitoring actually exerts a causal effect on memory, Emotionally arousing stimuli can lead to retrograde amnesia for preceding events and anterograde amnesia for subsequent events. When gauging the magnitude of cognitive cost, expressive suppression was compared with self-distraction, which was described as simply not trying to think about something. Other researchers have used brain scans, including positron emission tomography (PET) scans, to learn how people process and retain information. This study aimed at investigating the roles of the 5-HT1BR, and its adapter protein p11, in emotional memory and object … Visual sensory memory is known as iconic memory.  Based on these findings it has been suggested that the dual enhancing and impairing effects on memory are not an inevitable consequence of emotional arousal. Because of its role in processing emotional information, the amygdala is also involved in memory consolidation: the process of transferring new learning into long-term memory. The results showed that supporters recalled their past emotions as having been more consistent with their current appraisals of Perot than they actually were. A recent study found heightened self- monitoring efforts among suppressors relative to control participants. Contrary to what President Bush recalled, no one saw the first plane hit, except people on the ground near the twin towers. Changes in dendritic morphology: __ A. occur spontaneously over days or weeks. A Laser Beam. In fact, memory can be so frail that we can convince a person an event happened to them, even when it did not. (2003) argued that when arousal is induced thematically (i.e., not through the sudden appearance of a discrete shocking stimulus such as a weapon but rather through involvement in an unfolding event plot and empathy with the victim as his or her plight becomes increasingly apparent), memory enhancements of details central to the emotional stimulus need not come at the expense of memory impairment of peripheral details. Through evolution, this process of learning became genetically embedded in humans and all animal species in what is known as flight or fight instinct. Contextual effects occur as a result of the degree of similarity between the encoding context and the retrieval context of an emotional dimension. A somewhat different contextual effect stemmed from the recently made distinction between thematical and sudden appearance of an emotionally arousing event, suggesting that the occurrence of memory impairments depends on the way the emotional stimuli are induced.
