“…These peri-oddball effects are modulated by task (Anderson, Wais, & Gabrieli, 2006), stimulus onset asynchrony (SOA) (Schmidt & Schmidt, 2016;Tulving, 1968), retention intervals and arousal characteristics of the items (Mather & Sutherland, 2011;Schmidt & Schmidt, 2016). Furthermore, peri-oddball effects have been proposed to occur as an encoding disruption of the item preceding the emotional stimulus at the synaptic and/or systems level (Strange et al, 2003;Strange & Galarza-Vallejo, 2016). Others, however, have proposed that retrograde amnesic effects in free recall could be due to item unavailability at retrieval, and can be reversed by cueing recall (Detterman, 1976).…”

Conditional response probability (CRP) analyses applied to free recall data indicate that recall occurs for contiguous items with forward-directionality, thought to reflect the shared encoding context of nearby items. We hypothesized that a context disruption, produced by presenting infrequent oddballs, would modulate CRP curves, increasing the forward-flow of recall due to strong binding of items presented after these oddballs to the new encoding context. Seventy young, healthy male and female participants encoded word lists containing either emotional or perceptual oddballs at varying stimulus onset asynchronies (SOA) followed by free recall. Serial recall transitions from emotional, but not perceptual, oddballs were enhanced in the forward direction except at the shortest SOA (1s). The present results provide empirical evidence of CRP modulation selectively by emotional salience and suggest that recall patterns after presenting emotional and perceptual oddballs are mediated by different mechanisms.

“…The authors discuss their results with respect to the "glutamate amplifies noradrenergic effects" (GANE) model (explained in detail in Mather, Clewett, Sakaki, & Harley, 2016). However, this explanation is subject to current debate, with authors proposing an alternative model (Strange & Galarza-Vallejo, 2016) that assumes non-linear shifts in locus coeruleus (LC) activity as the underlying mechanism for the bi-directional effects of negative deviants on preceding neutral standard information.…”

Emotional oddball: A review on memory effects

How do emotional stimuli influence perception, attention, and ultimately memory? This debate at the cross-section of emotion and cognition research has a long tradition. The emotional oddball paradigm (EOP) has frequently been applied to investigate the detection and processing of (emotional) change detection (Schlüter & Bermeitinger, 2017). However, the EOP has also been used to reveal the effects of emotional deviants on memory for serially presented stimuli. In this integrative article, we review the results of 29 experiments published between the years 2000 and 2017. Based on these data, we provide an overview of how the EOP is applied in the context of memory research. We also review and integrate the empirical evidence for memory effects in the EOP (with a special focus on retrograde and anterograde emotion-induced effects) and present theories of emotional memory as well as their fit with the results obtained by the EOP. Directions for future research are presented that would help to address important issues of the current debate around emotion-induced memory effects.

“…Furthermore, peri-oddball effects (i.e. for items surrounding the oddballs) have been proposed to occur as an encoding disruption of the item preceding the emotional stimulus at the synaptic and/or systems level [ 8 , 14 ]. Others, however, have proposed that retrograde amnesic effects in free recall could be due to item inaccessibility at retrieval, which can disappear by cueing recall [ 15 ].…”

As we navigate our day-to-day lives, we regularly adapt our behaviour according to what we predict may happen next in a given context. When an unexpected event occurs, our predictions about the world are disrupted and must be updated. Unexpected, isolated events, particularly with high emotionality, are also better recalled. In the present work, we investigated how oddballs affect recall dynamics. Seventy young, healthy participants encoded word lists containing either emotional or perceptual oddballs at varying stimulus onset asynchronies followed by free recall. It is well established that after recalling an item, we have a higher probability of recalling items encoded nearby, particularly those that were encoded after the item was recalled, a phenomenon known as forward contiguity of recall. We tested how novelty (oddballs versus control words) modulated forward contiguity as a function of salience type (emotional versus perceptual). The present results provide empirical evidence of forward contiguity modulation selectively by emotional salience and suggest that recall patterns after presenting emotional and perceptual oddballs are mediated by different mechanisms.
