CONVERSATIONAL MEMORY

While there has recently been a notable increase in attempts by memory researchers to focus on more naturalistic stimuli little attention has been paid to conversations. Conversations represent stimuli that are distinctly different in a number of ways from most other stimuli that people are required to remember. Conversations are jointly created, constantly updated, and necessarily are readily accessible by participants. The present study, exploring people's memory for natural conversations in which they participate, finds that even after only five minutes people are able to recollect only about 10% of what was said in a social exchange. Further, the mode of recall (written versus oral) and the presence and type of memory goals affected what and how much of the interaction was recalled. Subjects also remembered more of their partner's comments in the interaction than their own. Finally, oral communication anxiety affected both the production of discourse in the conversations and recall of the interactions, while writing apprehension impacted subjects' written recalls of their conversations.     

Actors', partners', and observers' perceptions of sarcasm

This study compared actors', partners', and observers' perceptions of the amount of sarcasm used by participants (n = 80) in videotaped conversations. Significant differences were found among perceptions of actors, partners, and observers. Of the three perspectives, actors perceived themselves as using the greatest amount of sarcasm, followed by partners' perceptions of actors. Observers perceived actors as using the least amount of sarcasm. Correlations conducted to assess whether partners and observers recognized actors' individual attempts at sarcasm during the conversations were generally low.     

Witnesses’ memory for events and faces under elevated levels of intoxication

Research on alcohol and witness memory has burgeoned over the last decade. However, most studies have tested participants at relatively low breath alcohol concentration (BAC) levels, unrepresentative of those encountered by officers in the field. To examine how higher intoxication levels might impair witness memory for events and faces, the current research tested participants’ ability to recall a mock crime at elevated BAC levels (>.08%). The BAC levels of bar patrons (N?=?138) were recorded before witnessing a video-taped mock crime. Participants were then interviewed using free recall and cued questions and shown a six-person target-present or target-absent lineup. Results show that alcohol negatively affected both the quantity and quality of recall. Regardless of question format, alcohol also reduced the percentage of accurate information elicited from witnesses; however, only cued questions increased the percentage of inaccurate information reported. Intoxication had no effect on identification accuracy. These findings suggest that the encoding and storage systems for faces and events may be impacted differently by alcohol. Our results also highlight the importance of including higher BAC levels when examining the effects of alcohol on witness memory.     

Autobiographical memory functions in young Japanese men and women

The present study examined whether the three major functions of autobiographical memory observed in Western societies (i.e., directing-behaviour, social-bonding and self-continuity) also exist in an East Asian society. Two self-report measures were used to assess the autobiographical memory functions of Japanese men and women. Japanese young adults (N = 451, ages 17–28 years) first completed the original Thinking About Life Experiences (TALE) Questionnaire. They subsequently received three TALE items that represented memory functions and attempted to recall a specific instance of memory recall for each item. Confirmatory factor analyses on the TALE showed that the three functions were replicated in the current sample. However, Japanese participants reported lower levels of all three functions than American participants in a previous study. We also explored whether there was an effect of gender in this Japanese sample. Women reported higher levels of the self-continuity and social-bonding functions than men. Finally, participants recalled more specific instances of memory recall for the TALE items that had received higher ratings on the TALE, suggesting that the findings on the first measure were supported by the second measure. Results are discussed in relation to the functional approach to autobiographical memory in a cross-cultural context.     

Situation models and memory: The effects of temporal and causal information on recall sequence

Participants watched an episode of the television show Cheers on video and then reported free recall. Recall sequence followed the sequence of events in the story; if one concept was observed immediately after another, it was recalled immediately after it. We also made a causal network of the show's story and found that recall sequence followed causal links; effects were recalled immediately after their causes. Recall sequence was more likely to follow causal links than temporal sequence, and most likely to follow causal links that were temporally sequential. Results were similar at 10-minute and 1-week delayed recall. This is the most direct and detailed evidence reported on sequential effects in recall. The causal network also predicted probability of recall; concepts with more links and concepts on the main causal chain were most likely to be recalled. This extends the causal network model to more complex materials than previous research.     

The subjective organization of input and output events in memory

In order to study the organization of memory for self-performed actions, 80 participants were presented with 20 action phrases for ten consecutive study-test cycles. Enactment was manipulated both in the input phase and in the output phase by having participants say or enact the phrases during encoding and/or during testing. Enactment at input or output generally enhanced both the quantity and the accuracy of recall and also improved output monitoring. More important, subjective organization, as indexed by the tendency to recall the same two phrases successively across repeated recall tests, was significant for all conditions, even on the first pair of trials, and increased systematically with repeated study-test cycles. Enactment neither impaired nor enhanced the amount of organization, and in all conditions a positive correlation was obtained between recall and subjective organization. Some commonalities in the nature of memory organization were found across all conditions. The results suggest that enactment may lead to more differentiated memory traces, resulting in more accurate recall. Although subjective organization was clearly observed when enactment was involved, its contribution to the enhancement of recall deserves further examination.

Collaboration reduces the frequency of false memories in older and younger adults

Older (mean age = 74.23) and younger (mean age = 33.50) participants recalled items from 6 briefly exposed household scenes either alone or with their spouses. Collaborative recall was compared with the pooled, nonredundant recall of spouses remembering alone (nominal groups). The authors examined hits, self-generated false memories, and false memories produced by another person's (actually a computer program's) misleading recollections. Older adults reported fewer hits and more self-generated false memories than younger adults. Relative to nominal groups, older and younger collaborating groups reported fewer hits and fewer self-generated false memories. Collaboration also reduced older people's computer-initiated false memories. The memory conversations in the collaborative groups were analyzed for evidence that collaboration inhibits the production of errors and/or promotes quality control processes that detect and eliminate errors. Only older adults inhibited the production of wrong answers, but both age groups eliminated errors during their discussions. The partners played an important role in helping rememberers discard false memories in older and younger couples. The results support the use of collaboration to reduce false recall in both younger and older adults.     

Remembering a criminal conversation: beyond eyewitness testimony

Unlike the important body of work on eyewitness memory, little research has been done on the accuracy and completeness of "earwitness" memory for conversations. The present research examined the effects of mode of presentation (audiovisual/ auditory-only) on witnesses' free recall for utterances in a criminal conversation at different retention intervals (immediate/delayed) within a single experiment. Different forms of correct recall (verbatim/gist) of the verbal information as well as different types of errors (distortions/fabrications) were also examined. It was predicted that participants in the audiovisual modality would provide more correct information, and fewer errors than participants in the auditory-only modality. Participants' recall was predicted to be impaired over time, dropping to a greater extent after a delay in the auditory-only modality. Results confirmed these hypotheses. Interpretations of the overall findings are offered within the context of dual-coding theory, and within the theoretical frameworks of source monitoring and fuzzy-trace theory.     

Feeling of knowing for names in response to faces

Participants were asked to recall the names when shown photographs of faces in both a semantic task (Experiment 1) and an episodic task (Experiments 2 and 3). When recall failed, feeling of knowing (FOK) ratings were solicited. In addition, participants reported on the strategies that they used to make their ratings, whether they could recall other pieces of information (the target-accessibility strategy, e.g., Koriat, A. (1993). How do we know that? The accessibility model of the feeling of knowing. Psychological Review, 100, 609–639) or whether the faces simply looked familiar (the cue-familiarity strategy, e.g., Schwartz, B. L., & Metcalfe, J. (1992). Cue familiarity but not target accessibility enhances feeling of knowing ratings. Journal of Experimental Psychology: Learning, Memory, and Cognition, 18, 1074–1083). In all experiments, FOK ratings were fairly accurate in that participants were successful in predicting their performance on a subsequent recognition test. More importantly, participants reported using the cue-familiarity strategy more often, although they gave higher FOK ratings when they reported using the target-accessibility strategy. The FOK ratings that were given using the two strategies were equally accurate.     

Five weeks of immersive reminiscence therapy improves autobiographical memory in Alzheimer’s disease

ABSTRACT

We examined the effects of a new Immersive Reminiscence Therapy (IRT) programme on cognitive function, including autobiographical memory, in a sample Alzheimer’s disease (AD) patients. A total of 43 AD patients with mild to moderate disease severity were randomly assigned to either an intervention group (n?=?22, MMMSE?=?20.77), or a control group (n?=?21, MMMSE?=?19.24). The intervention group received one weekly group-based session of IRT for five weeks in an authentic 1950s style museum environment, matching the time of the participants’ youth. IRT included semi-structured conversations about the past. The control group received standard care. We assessed performance on cognitive function and autobiographical memory at baseline and post-intervention. Five weeks of IRT enhanced subsequent autobiographical memory performance, when participants were cued by concrete objects dated to their youth. Object-cued memories reported post intervention included a significantly higher degree of episodic details and higher word counts. The intervention showed no effect on the Autobiographical Memory Interview or word-cued recall. Global cognitive function and semantic autobiographical memory performance increased across time for both groups. Our findings demonstrate that immersion into a setting, rich on concrete cues dated to the participants’ youth can improve autobiographical remembering.     

An examination of the Self-Administered Interview as a verbal veracity assessment tool

The self-administered interview (SAI) is a written eyewitness recall tool that elicits more information from cooperative witnesses than written free recall (WFR) formats. To date, SAI research has examined the accounts of cooperative people providing honest reports. In the current experiment, truthful and fabricating participants (N = 128) either completed a WFR or a SAI after witnessing a crime (initial account). After a 1-week delay, participants were interviewed verbally (subsequent interview). Truth tellers reported significantly more detail than liars in both the initial account and subsequent interview, and participants who completed the SAI reported more detail than those completing the WFR. Truth tellers repeated and omitted more information in the subsequent interview than liars; however, there was no significant difference in the number of reminiscent details reported. Although the SAI is effective in eliciting information as an initial eyewitness reporting tool, no benefits for the detection of deception were demonstrated.     

A comparison of Chinese and American memories for public events

Memory for public events was compared across Chinese and U.S. participants to explore competing explanations for cultural differences in flashbulb memories. Participant recall of the canonical features of events was more detailed and more likely to include a specific time in the United States than in the Chinese reports. Vividness was positively correlated with the flashbulb memory scores only in the U.S. sample. In both cultures, emotion, national importance, and thinking about the event predicted vividness and recall of memory details. Chinese participants reported primarily disasters and social events, and their memories were more likely to include international events than U.S. participants. The U.S. participants recalled primarily political events and terrorism. These results suggest that culture has important influences on the quantity, level of detail, completeness, and vividness of autobiographical memories as well as on the types of events triggering flashbulb memories.     

An exploratory analysis of sex differences in gossip

This study examined sex differences in the quantity, targets, tone, and topics of gossip in the conversations of 76 male and 120 female college students. Contrary to popular beliefs, results indicated that the gossip of men and women contained similarities as well as differences. The data revealed that women spent more time gossiping than men and that women were much more likely than men to gossip about close friends and family members. However, no significant sex differences were uncovered regarding the derogatory tone of gossip and men and women were found to gossip about many of the same topics.We are grateful to Karl Seman, Marilla Ross, Robin Ansher, and Jack Schmaly, who served as observers during the data-collection phase of the study, and to Richard Weiner, who conducted the statistical analysis. We also gratefully acknowledge the contributions made by Ralph L. Rosnow.     

Partners and Fellow Patients: Two Sources of Emotional Support for Women with Breast Cancer

This study examined the helping process that occurred when 26 breast cancer patients (the disclosers) talked about their illness-related concerns with their partner and, in a separate conversation, with a fellow patient (the volunteer helpers). The conversations were rated by trained observers and by the disclosers in terms of several process and outcome variables. From the observers' perspective, the volunteer helpers were more helpful, empathic, and supportive, less critical, and used more self-disclosure than the partners. Disclosers did not differentiate between the two types of helper, and gave generally high ratings to both conversations. Strengths and weaknesses of each type of helper were identified. Findings are discussed in relation to the literature on formal and informal helping, and implications for training nonprofessional helpers are suggested.     

Theory of Mind Understanding and Conversational Patterns in Middle Childhood

The author investigated the longitudinal relations between theory of mind (ToM) understanding and perceptions of self and social conversations in 17 school-aged children (12 girls, 5 boys, age 8–12 years). ToM was assessed at Time 1 (T1; M age = 8 years 5 months, SD = 8.7 months, and perceptions of self and conversational experiences assessed two years later at Time 2 (T2; M age = 10 years 4 months, SD = 7.9 months. Most importantly, longitudinal findings showed that children who scored relatively high on ToM at T1 reported relatively lower perceptions of self-worth and higher number of mental states verbs in their perceptions of peer and family conversations at T2. Significant negative longitudinal associations were found between children's number of siblings and their perceptions of self-worth (T1) and number of cognitive terms in their perceptions of peer and family conversations (T2). Frequency analysis suggested that girls’ perceptions of conversations referred to more social and psychological aspects of self and relationships, whereas boys focused mainly on physical activities. Most children were more likely to prefer listening to talking during social conversations. The majority of children reported feelings of mixed or ambiguous emotions during experiences of silence. Implications for socioemotional and cognitive development in early adolescents are discussed.     

CONCEPTUALIZING CONVERSATIONAL COMPLEXITY

A successful conversation requires participants to have knowledge of both the topic under discussion and the nature of conversation. This study asks whether people who are more sophisticated in their representation of conversation behave differently than their less sophisticated counterparts. This issue was probed by devising two operationalizations of what we call Conversational complexity. The two measures assessed peoples' constructs about conversation (operationalized by a measure of construct differentiation) and the manner in which people psychologically structure conversations (via a sorting task tapping the degree to which they focus on the surface features, or deeper structures, of conversations). Individuals who completed the two measures of complexity also participated in conversations and completed a number of personality indices. Each operationalization of conversational complexity was positively correlated with a variety of conversational involvement behaviors, measures of conversational enjoyment and person complexity, and memory for the interactions. Generally speaking, effective interactants who enjoyed conversations and recalled them well tended to have more constructs about conversations and psychologically represented conversations at a deeper level than their counterparts.     

The role of event relevance and congruence to social groups in flashbulb memory formation

ABSTRACT

Flashbulb memories are vivid, confidently held, long-lasting memories for the personal circumstances of learning about an important event. Importance is determined, in part, by social group membership. Events that are relevant to one’s social group, and furthermore, are congruent with the prior beliefs of that group, should be more likely to be retained as flashbulb memories. The Fukushima nuclear disaster was relevant to ongoing political conversations in both Germany and the Netherlands, but, while the disaster was congruent with German beliefs about the dangers of nuclear energy, it was incongruent with Dutch support for nuclear power. Danish participants would not have found the disaster to be particularly relevant. Partially consistent with this prediction, across two samples (N?=?265 and N?=?518), German participants were most likely to have flashbulb memories for the Fukushima disaster. Furthermore, event features thought to be related to flashbulb memory formation (e.g. ratings of importance and consequentiality) also differed as a function of nationality. Spontaneously generated flashbulb memories for events other than Fukushima also suggested that participants reported events that were relevant to national identity (e.g. the Munich attacks for Germans, the Utøya massacre for Danes, and Malaysian Airlines flight MH-17 for Dutch participants).     

Being a good witness: The roles of benevolence and working memory capacity in rapport’s effect on eyewitness memory

Prior studies suggest that building rapport with eyewitnesses can produce measurable recall improvements, but the underlying mechanisms of rapport’s possible effects on recall remain underexplored. The present study investigated two possible mechanisms for rapport’s impact: (1) improved working memory capacity and (2) increased benevolence. Participants (N = 105) viewed a mock theft video, followed by one of two possible pre-interview interactions: rapport-building or a control interaction. Next, participants completed measures of working memory, altruism, and benevolence (pre-interview and post-interview), before recalling details of the theft. Analyses revealed that, when controlling for the effects of the interaction duration and participants’ pre- and post-interview benevolence, rapport did not affect eyewitness recall directly. However, rapport building did increase benevolence measured after and associated with the substantive eyewitness interview, which in turn predicted more accurate and new details reported, and fewer subjective/other details reported. These findings support benevolence toward the interviewer as a mechanism behind rapport’s effect on eyewitness recall. Implications for investigative interviews in relation to benevolence and motivating reciprocation are discussed.
