Abstract: Voice and silence are socially constructed in conversational interactions between speakers and listeners that are influenced by canonical cultural narratives which define lives and selves. Arguing from feminist and sociocultural theories, I make a distinction between being silenced and being silent; when being silenced is contrasted with voice, it is conceptualised as imposed, and it signifies a loss of power and self. But silence can also be conceptualised as being silent, a shared understanding that need not be voiced. More specifically, culturally dominant narratives provide for shared understandings that can remain silent; deviations from the norm call for voice, and thus in this case silence is power and voice expresses loss of power. At both the cultural and the individual level, there are tensions between culturally dominant and prescriptive narratives and narratives of resistance and deviation, leading to an ongoing dialectic between voice and silence. I end with a discussion of why, ultimately, it matters what is voiced and what is silenced for memory, identity and well-being.

Abstract: This research investigated the cognitive correlates of false memories that are induced by the misinformation paradigm. A large sample of Chinese college students (N=436) participated in a misinformation procedure and also took a battery of cognitive tests. Results revealed sizable and systematic individual differences in false memory arising from exposure to misinformation. False memories were significantly and negatively correlated with measures of intelligence (measured with Raven's Advanced Progressive Matrices and Wechsler Adult Intelligence Scale), perception (Motor-Free Visual Perception Test, Change Blindness, and Tone Discrimination), memory (Wechsler Memory Scales and 2-back Working Memory tasks), and face judgement (Face Recognition and Facial Expression Recognition). These findings suggest that people with relatively low intelligence and poor perceptual abilities might be more susceptible to the misinformation effect.

Abstract: This paper examines predictions concerning the absence of hindsight bias. Some hypothesise that because hindsight bias increases with outcome "surprisingness", only unsurprising outcomes will remove it. Others suggest the opposite-that very surprising outcomes will reduce or reverse the bias. A proposed sense-making model suggests that unexpected outcomes (i.e., initially surprising) invoke greater sensemaking, which typically produces greater hindsight bias. If the process is not successful, however, the bias may be reduced or reversed. Expected outcomes will also produce little hindsight bias, but only because they invoke relatively little sensemaking in the first place. Feelings of surprise arising from sensemaking (i.e., resultant surprise) should be inversely related to hindsight bias. Results of four experiments provide support for the model. A secondary goal was to determine the boundaries of a defensive-processing mechanism also thought to reduce hindsight bias for negative, self-relevant outcomes. Results suggest that a sense of responsibility for the outcome may be necessary for defensive processing to be activated.

Abstract: Congenital amusia is a disorder that affects the perception and production of music. While amusia has been associated with deficits in pitch discrimination, several reports suggest that memory deficits also play a role. The present study investigated short-term memory span for pitch-based and verbal information in 14 individuals with amusia and matched controls. Analogous adaptive-tracking procedures were used to generate tone and digit spans using stimuli that exceeded psychophysically measured pitch perception thresholds. Individuals with amusia had significantly smaller tone spans, whereas their digits spans were a similar size to those of controls. An automated operation span task was used to determine working memory capacity. Working memory deficits were seen in only a small subgroup of individuals with amusia. These findings support the existence of a pitch-specific component within short-term memory and suggest that congenital amusia is more than a disorder of fine-grained pitch discrimination.

Abstract: A large body of literature on "within-individual retrieval-induced forgetting" (WI-RIF; Anderson, Bjork, & Bjork, 1994) shows that repeatedly retrieving some items, while not retrieving other related items, facilitates later recall of the practised items, but inhibits later recall of the non-practised related items. This robust effect has recently been extended to "socially shared retrieval-induced forgetting" (SS-RIF; Cuc, Koppel, & Hirst, 2007). People who merely listen to a speaker retrieving some, but not other, items-even people participating as speakers or listeners in conversations-show the same facilitation and inhibition. We replicated and extended the SS-RIF effect with a structured story (Experiment 1) and in a free-flowing conversation about the story (Experiment 2). Specifically, we explored (1) the degree to which participants subsequently form a coherent "collective memory" of the story and (2) whether schema consistency of the target information influences both WI-RIF and SS-RIF. In both experiments, speakers and listeners showed RIF (that is, WI-RIF and SS-RIF, respectively), irrespective of the schema consistency of the story material. On final recall, speakers and listeners described similar renderings of the story. We discuss these findings in terms of the role of "silences" in the formation of collective memories.

Abstract: Testing, or memory retrieval, is a powerful way to enhance long-term retention of studied material Recent studies have shown that testing can also benefit later retention of related but nontested material (a finding known as retrieval-induced facilitation, Chan, McDermott, & Roediger, 2006), but the long-term consequences of this benefit is unknown In the current experiment three retention intervals—20 minutes, 24 hours, 7 days—were used to assess the effects of testing on subsequent recall of the nontested material The results indicate that the magnitude of retrieval-induced facilitation, like that of the testing effect (ie, the memorial benefit of testing on the tested material), increases with delay at the beginning (ie, between 20 minutes and 24 hours) but asymptotes afterward (ie, between 24 hours and 7 days) Theoretical and applied implications of this finding are discussed

Abstract: Procedural skills such as riding a bicycle and playing a musical instrument play a central role in daily life. Such skills are learned gradually and are retained throughout life. The present study investigated 1-year retention of procedural skill in a version of the widely used serial reaction time task (SRTT) in young and older motor-skill experts and older controls in two experiments. The young experts were college-age piano and action video-game players, and the older experts were piano players. Previous studies have reported sequence-specific skill retention in the SRTT as long as 2 weeks but not at 1 year. Results indicated that both young and older experts and older non-experts revealed sequence-specific skill retention after 1 year with some evidence that general motor skill was retained as well. These findings are consistent with theoretical accounts of procedural skill learning such as the procedural reinstatement theory as well as with previous studies of retention of other motor skills.

Abstract: The current study begins the exploration of relationship-defining memories (i.e., the first time someone met their spouse) across adulthood. Men and women ranging from 20 to 85 years old (N=267; M age=47.19) completed a measure of marital satisfaction, wrote a relationship-defining memory, and answered questions about the quality of their memory (i.e., vividness, valence, emotional intensity, and rehearsal). Data were collected online. Results indicate that individuals over 70 and those younger than 30 rehearsed relationship-defining memories most often. Women in midlife also reported more vivid memories. The quality of relationship-defining memories also predicted marital satisfaction. Relationship-defining memories that were more vivid, positive, emotionally intense, and rehearsed related to higher marital satisfaction. Age and gender differences were minimal. Results are discussed in the context of the adaptive social function of autobiographical memories, such that these memories might have a role in influencing marital satisfaction across adulthood.

Abstract: This paper investigates the identity implications of silence about genocide in commemorations of American Thanksgiving. In Study 1 we assessed the co-occurrence of national glorification themes with different forms of silence in commemoration products by conducting a content analysis of presidential Thanksgiving proclamations. In Study 2 we examined the extent to which different commemoration products are infused with particular beliefs and desires by measuring participants' reactions to different Thanksgiving commemorations-a literal-silence condition that did not mention Indigenous Peoples, an interpretive-silence condition that mentioned Indigenous Peoples but did not explicitly mention genocidal conquest, and an anti-silence condition that did mention genocidal conquest-as a function of national glorification. In Study 3 we manipulated exposure to different Thanksgiving commemorations (with associated forms of silence) and assessed the impact on national glorification and identity-relevant action. Results provide evidence for the hypothesised, bi-directional relationship between national glorification and silence about genocide in commemorations of American Thanksgiving.

Abstract: In two studies, participants studied 30 lists of 50 words and were tested on 30 lists of 100 words. Item-level multiple regression analyses were conducted on hits, false alarms, hits minus false alarms, d', and C. The predictor variables were objective frequency, subjective frequency, imageability, orthographic similarity, phonological similarity, phonological-to-orthographic N (PON), age of acquisition (AoA), and word length. The regression equations accounted for 45.9% of the variance in hit rates, 14.9% of the variance in false alarm rates, and 29.2% of the variance in hits minus false alarms. Other noteworthy results were that: (a) hit rates positively correlated with false alarms, (b) objective frequency negatively correlated with both hit rates and false alarm rates, (c) AoA positively correlated with hit rates and negatively correlated with false alarm rates, (d) length negatively correlated with hit rates and positively correlated with false alarm rates, (e) orthographic uniqueness was positively correlated with hit rates and negatively correlated with false alarms, (f) PON positively correlated with false alarm rates, (g) imageability produced the typical mirror pattern, and (h) imageability and length were the strongest predictors of performance. Results were largely compatible with predictions made by single- and dual-process theories of recognition memory.

Abstract: According to the dual representation theory of PTSD, intrusive trauma images and intrusive verbal thoughts are produced by separate memory systems. In a previous article it was shown that after watching an aversive film, participants in non-movement conditions reported more intrusive images than participants in a free-to-move control condition (Hagenaars, Van Minnen, Holmes, Brewin, & Hoogduin, 2008). The present study investigates whether the experimental conditions of the Hagenaars et al. study had a different effect on intrusive thoughts than on intrusive images. Experiment 2 further investigated the image-thoughts distinction by manipulating stimulus valence (trauma film versus neutral film) and assessing the subsequent development of intrusive images and thoughts. In addition, both experiments studied the impact of peri-traumatic emotions on subsequent intrusive images and thoughts frequency across conditions. Results showed that experimental manipulations (non-movement and trauma film) caused higher levels of intrusive images relative to control conditions (free movement and neutral film) but they did not affect intrusive thoughts. Peri-traumatic anxiety and horror were associated with subsequent higher levels of intrusive images, but not intrusive thoughts. Correlations were inconclusive for anger and sadness. The results suggest intrusive images and thoughts can be manipulated independently and as such can be considered different phenomena.

Abstract: Research on retrieval-induced forgetting has shown that the selective retrieval of some information can cause the forgetting of other information. Such forgetting is believed to result from inhibitory processes that function to resolve interference during retrieval. The current study examined whether individuals with ADHD demonstrate normal levels of retrieval-induced forgetting. A total of 40 adults with ADHD and 40 adults without ADHD participated in a standard retrieval-induced forgetting experiment. Critically, half of the items were tested using category cues and the other half of the items were tested using category-plus-one-letter-stem cues. Whereas both ADHD and non-ADHD participants demonstrated retrieval-induced forgetting on the final category-cued recall test, only non-ADHD participants demonstrated retrieval-induced forgetting on the final category-plus-stem-cued recall test. These results suggest that individuals with ADHD do have a deficit in the inhibitory control of memory, but that this deficit may only be apparent when output interference is adequately controlled on the final test.

Abstract: Prior work suggests that receiving feedback that one’s response was correct or incorrect (right/wrong feedback) does not help learners, as compared to not receiving any feedback at all (Pashler, Cepeda, Wixted, & Rohrer, 2005). In three experiments we examined the generality of this conclusion. Right/ wrong feedback did not aid error correction, regardless of whether participants learned facts embedded in prose (Experiment 1) or translations of foreign vocabulary (Experiment 2). While right/wrong feedback did not improve the overall retention of correct answers (Experiments 1 and 2), it facilitated retention of low-confidence correct answers (Experiment 3). Reviewing the original materials was very useful to learners, but this benefit was similar after receiving either right/wrong feedback or no feedback (Experiments 1 and 2). Overall, right/wrong feedback conveys some information to the learner, but is not nearly as useful as being told the correct answer or having the chance to review the to-be-learned materials.

Abstract: Retrieving an item or set of items from memory can cause the forgetting of other related items in memory; a phenomenon known as retrieval-induced forgetting. According to the inhibitory account of retrieval-induced forgetting, in searching for a particular item, other items that are related but incorrect can vie for access. Inhibition functions to decrease the accessibility of such interfering items, thereby facilitating access to the target item. Experiments 1 and 2 replicated recent work suggesting that retrieval success is not a necessary condition for retrieval-induced forgetting to occur. Interfering items were forgotten even when retrieval practice was designed to be impossible. Experiments 3 and 4 employed the impossible retrieval practice procedure to examine the time-course of forgetting across a single retrieval practice trial. Results support the inhibitory account of retrieval-induced forgetting and offer insight into the dynamics of how and when inhibition plays a role in retrieval.

Abstract: The testing effect is the finding that prior retrieval of information from memory will result in better subsequent memory for that material. One explanation for these effects is that initial free recall testing increases the recollective details for tested information, which then becomes more available during a subsequent test phase. In three experiments we explored this hypothesis using a source-monitoring test phase after the initial free recall tests. We discovered that memory is differentially enhanced for certain recollective details depending on the nature of the free recall task. Thus further research needs to be conducted to specify how different kinds of memorial details are enhanced by free recall testing.

Abstract: A commonly held assumption is that processes underlying explicit and implicit memory are distinct. Recent evidence, however, suggests that they may interact more than previously believed. Using the remember-know procedure the current study examines the relation between recollection, a process thought to be exclusive to explicit memory, and performance on two implicit memory tasks, lexical decision and word stem completion. We found that, for both implicit tasks, words that were recollected were associated with greater priming effects than were words given a subsequent familiarity rating or words that had been studied but were not recognised (misses). Broadly, our results suggest that non-voluntary processes underlying explicit memory also benefit priming, a measure of implicit memory. More specifically, given that this benefit was due to a particular aspect of explicit memory (recollection), these results are consistent with some strength models of memory and with Moscovitch's (2008) proposal that recollection is a two-stage process, one rapid and unconscious and the other more effortful and conscious.

Abstract: This study compared life story memories of emerging adults and early adolescents to other autobiographical memories. Participants described three scenes of their respective life stories, a high point, low point, and turning point narrative, and described the connections between them in a fourth narrative. Participants also related four autobiographical narratives from corresponding time periods for comparison. Narratives were analysed for two measures of causal coherence, narrative complexity and meaning making, and for thematic coherence. Life story narratives contained more self-related lessons and insights and greater recognition of complexity than non-life-story narratives, but these differences were confined to narratives of turning points and connections between events. Thematic connections between narratives were more abstract and self-related in life story narratives. Emerging adults' narratives, when compared to those of early adolescents, showed more evidence of self-related abstract thinking and recognition of multiple dimensions. Findings indicate consistent ways in which life story memories differ from other autobiographic memories, and show evidence of development in adolescence.

Abstract: Two studies examined the ability of the life script account to explain the reminiscence bump for emotionally charged autobiographical memories among Malaysian participants. In Study 1 volunteers, aged 50-90 years, participated in a two-phased task. In the first phase, participants estimated the timing of 11 life events (both positive and negative) that may occur in a prototypical life course within their own culture. Two weeks later the participants retrieved the same set of events from their lives and reported how old they were when those events occurred. In the second study 92 undergraduate students produced life scripts for the same 11 events. The findings revealed reminiscence bumps in both life script and retrieval curves for the memories judged happiest, most important, most in love, and most jealous. A reminiscence bump was also noted for success, although this was later in the lifespan than other reminiscence bumps. It was suggested that the life scripts can be used as an alternative account for the reminiscence bump, for highly positive and occasionally for negative autobiographical memories.

Abstract: Saccade-induced retrieval enhancement (SIRE) is the effect whereby making bilateral saccades enhances the subsequent retrieval of memories. Two experiments explored SIRE's potential to improve eyewitness evidence. Participants viewed slideshows depicting crimes, and received contradictory and additive misinformation about event details either once (Experiment 1) or three times (Experiment 2). Participants then performed saccades or a fixation control task before being tested on their memory for the slideshows and making confidence judgements. Saccades increased discrimination between seen and unseen event details regardless of whether or what type of misinformation was presented. Because prior studies indicated that SIRE might be more robust for individuals who are strongly right-handed versus not, we examined SIRE as a function of handedness and found that saccades improved memory for event details regardless of participants' handedness. However, participants who were not strongly right-handed had fewer false memories than participants who were strongly right-handed, extending previous findings of superior memory among individuals who are not strongly right-handed. Saccades also increased confidence in true memories (Experiment 1) and decreased confidence in false memories (Experiment 2). The results support SIRE's potential to improve eyewitness evidence.

Abstract: The dual process model assumes memory is based on recollection (retrieval with specific detail) or familiarity (retrieval without specific detail). A current debate is whether recollection is a threshold process or, like familiarity, is a continuous process. In the present study two continuous models and two threshold models of recollection were evaluated using receiver operating characteristic (ROC) analysis. These models included the continuous signal detection unequal variance model and the threshold dual process model. In the study phase of three experiments, objects were presented to the right or left of fixation. At test, participants made either remember-know responses or item confidence responses followed by source memory (spatial location) confidence ratings. Recollection-based ROCs were generated from source memory confidence ratings associated with "remember" responses (in Experiments 1-2) or the highest item confidence responses (in Experiment 3). Neither threshold model adequately fit any of the recollection-based ROCs. By contrast, one or both of the continuous models adequately fit all of the recollection-based ROCs. The present results indicate recollection and familiarity are both continuous processes.

Abstract: The term childhood amnesia refers to the inability of adults to remember events from their infancy and early childhood. If we plot the number of memories that adults can recall as a function of age during childhood, the number of memories reported increases gradually as a function of age. Typically, this finding has been used to argue that gradual changes in memory development contribute to a gradual decline in childhood amnesia during the preschool period. Alternatively, it is possible that pooling data across participants has obscured more abrupt, stage-like changes in the remission of childhood amnesia. In the present study we examined the number and distribution of childhood memories for individual participants. Six adults were repeatedly interviewed about their childhood memories. We found that the distribution of adults' early childhood memories may be less continuous than pooled data suggest. This finding has important implications for current explanations of childhood amnesia.

Abstract: Although contradictions with stored knowledge are common in daily life, people often fail to notice them. For example, in the Moses illusion, participants fail to notice errors in questions such as "How many animals of each kind did Moses take on the Ark?" despite later showing knowledge that the Biblical reference is to Noah, not Moses. We examined whether error prevalence affected participants' ability to detect distortions in questions, and whether this in turn had memorial consequences. Many of the errors were overlooked, but participants were better able to catch them when they were more common. More generally, the failure to detect errors had negative memorial consequences, increasing the likelihood that the errors were used to answer later general knowledge questions. Methodological implications of this finding are discussed, as it suggests that typical analyses likely underestimate the size of the Moses illusion. Overall, answering distorted questions can yield errors in the knowledge base; most importantly, prior knowledge does not protect against these negative memorial consequences.

Abstract: Research on autobiographical remembering has shown the intertwined relationship between the self and memory. Very little is known about the role of the self in the anticipation of the future. To investigate the association, European American (N=61) and Chinese (N=60) college students each reported two past autobiographical events and anticipated two future events, and described themselves in the past, present, and future. The results from a content analysis found that, regardless of culture, the future self and events were more positive and socially oriented than the past self and events. In general, European Americans provided more positive events and self-descriptions than Chinese. Men showed more personal focus in both experiences and self-descriptions than women at all time epochs. Importantly, independent of culture and gender, the self rather than the past events predicted the valence and personal focus of future events. These findings offer new insights into the dynamic relations between the self a...

Abstract: Involuntary memory chains are spontaneous recollections of the past that occur in a sequence. Much like semantic memory priming, this memory phenomenon has provided some insights into the nature of associations in autobiographical memory. The event-cueing procedure (a laboratory-based memory sequencing task) has also provided some insights into the nature of autobiographical memory organisation. However, while both of these memory-sequencing phenomena have exhibited the same types of memory associations (conceptual associations and general-event or temporal associations), both have also produced discrepant results with respect to the relative proportions of such associations. This study investigated the possibility that the results from event cueing are artefacts of various memory production responses. Using a number of different approaches we demonstrated that these memory production responses cause overestimates of general-event association. We conclude that for this reason, the data from involuntary me...

Abstract: While prior research has shown that proper names are more challenging to learn and remember than other types of information (e.g., occupations), little research has explored the role of metacognitive factors in proper name learning. Thus in four experiments participants learned, made predictions, and were tested on their memory for common nouns (i.e., occupations) and proper nouns (i.e., names). Results showed that memory predictions were consistently overconfident for names, whereas the discrepancy between predictions and performance was smaller for occupations. With experience, participants were able to modify predictions and, critically, Experiment 4 showed that improvements in the accuracy of memory predictions led participants to allocate more study time to names and thus improved memory for names. Such data suggest that theories of proper name learning should make provisions for deficits in metacognitive awareness.

Abstract: Conversations about the past can involve voicing and silencing; processes of validation and invalidation that shape recall. In this experiment we examined the products and processes of remembering a significant autobiographical event in conversation with others. Following the death of Australian celebrity Steve Irwin, in an adapted version of the collaborative recall paradigm, 69 participants described and rated their memories for hearing of his death. Participants then completed a free recall phase where they either discussed the event in groups of three or wrote about the event on their own. Finally, participants completed the original questionnaire again, both 1 week and 1 month after the free recall phase. Discussion influenced later memories for hearing of Irwin's death, particularly memories for emotion and shock. Qualitative analysis of the free recall phase suggested that during conversation a shared understanding of the event developed, but that emotional reactions to the event were silenced in ways that minimised the event's impact. These findings are discussed in terms of the processes and consequences of sharing public and personal memories in conversation.

Abstract: The current study examined predictions of memory performance as a function of the amount of information to be remembered. In four experiments participants studied and made judgements of learning (JOLs) for long or short lists of words. Results demonstrated that participants provided lower JOLs for long compared with short lists. However, whereas JOLs for short lists strongly corresponded with memory performance, participants' JOLs were consistently overconfident for long lists. Participants were unable to remedy this overconfidence for long lists even when provided information about the list length conditions or warned that a long list of words is difficult to learn. Only when given a prior list learning experience were JOLs for a long list consistent with memory performance. These data indicate that predictions of memory performance are sensitive to the amount of material TBR. However, predictions only correspond with the amount of information to-be-remembered under limited circumstances, providing support for frameworks which suggest that memory predictions are inferential in nature.

Abstract: Society's interest in sexual abuse waxes and wanes in ways that mirror the fluidity of memory narrated by trauma survivors. Although a great deal of research explores memory processes, including the neurophysiology of trauma, little considers the ways in which disclosure delays and socio-cultural pressures for silence appear in narratives of childhood sexual abuse survivors. This qualitative study examines the narratives of four female survivors and illustrates the importance of listening with an ear towards the various layers of silence held within them. The analysis draws attention to the potential limitations of memory research, including the importance of considering relational aspects when examining trauma narratives.

Abstract: How accurate are children when dating very long-term memories? Chinese and European Canadian 8-, 11-, and 14-year-olds (N=344) recalled and dated memories from before they went to school in a memory fluency task. Parents provided verification of children's memories and age estimates. Across all age and culture groups, a telescoping effect (i.e., events were dated as taking place more recently than they actually did) was found for earlier memories (before 48 months) and a reverse telescoping effect for later memories (after 48 months). Older children showed a greater tendency to telescope earlier memories and a weaker tendency to reverse telescope later memories than did younger children. Euro-Canadian children showed larger reverse telescoping than Chinese children. These are the first systematic findings concerning the accuracy of children's dating of very long-term memories. They shed new light on the phenomenon of telescoping and have implications for research on childhood amnesia.
