Destination memory in schizophrenia: "Did I told Elvis Presley about the thief?"

The influence of information generation on destination memory

To remember to whom we transmit information, we rely on destination memory, with worse performance occurring when participants share personal facts (e.g., my age is . . .) compared with interesting ones (e.g., a shrimp's heart is in its head). When reporting personal information, the internal attentional focus decreases the attentional resources available to associate that information with recipients, resulting in worse destination memory. Given that the poorer destination memory when participants transmitted personal facts was always compared with the transmission of interesting facts, in Experiment 1 (between-participants design: 41 participants) and Experiment 2 (within-participants design: 30 participants), we compared the generation and transmission of personal facts with the transmission of familiar proverbs. Again, the generation and transmission of personal facts hampered destination memory. Besides the type of information (personal vs. familiar proverbs), the conditions differed regarding the type of process (generation vs. transmission of information). To clarify the influence of generation on destination memory, in Experiment 3 (N = 31), participants (1) transmitted and (2) generated and transmitted familiar proverbs, and significant differences in destination memory between the conditions was not observed. In general, our experiments seem to support the assumption that transmitting personal information leads to worse destination memory not because participants generated the information but because personal facts drive the attentional focus to the self.

Destination memory disorders: At the junction between memory and socioaffective processing

The junction between memory dysfunction and socioaffective dysfunction is a complex area as research has typically been interested in one dysfunction rather than in the other. However, this junction can be studied under the lens of destination memory. Destination memory (i.e. the ability to remember to whom a piece of information was previously transmitted) is unique in that it draws on both memory and socioaffective processes. Research has demonstrated how destination memory is prone to distortions in neurological/psychiatric disorders. This paper aims to provide a focused review on the interplay between memory and socioaffective processes in the deterioration of destination memory within these disorders. It shows how both episodic memory and socioaffective dysfunction can jointly contribute to the decline in destination memory, although the contribution of each of the two factors may vary depending on the disorder.

"Choose it, and remember it": The impact of choice on destination memory

Destination memory can be defined as the capacity to remember to whom we transmit information. It is measured through the accuracy of retrieving the association between the information we transmit and the person to whom we transmit it. A destination memory procedure aims to emulate human interaction by sharing facts with celebrities (i.e., familiar faces) since we often communicate with people we know. However, the role of the choice about who we intend to transmit the information to has not been evaluated before. This paper investigated whether deciding with whom to share a piece of information benefits destination memory. We designed two experiments with different levels of cognitive load, increasing it from Experiment 1 to Experiment 2. The experiments included two conditions: the choice condition, in which participants chose from two options to whom they desired to share a fact, and the no-choice condition, in which participants simply shared facts with celebrities without the possibility of a choice. Experiment 1 suggested that a choice component did not affect destination memory. However, when in Experiment 2 we raised the cognitive load by increasing the number of stimuli, we found that selecting the recipient during the more challenging task provided an advantage in destination memory. This result is congruent with the explanation that the shift of the participants' attentional resources to the recipient, caused by the choice component, leads to a destination memory improvement. In sum, it seems that a choice component can improve destination memory only under demanding attentional conditions.

"What Did I Tell This Sad Person?": Memory for Emotional Destinations in Korsakoff's Syndrome

We investigated destination memory, defined as the ability to remember to whom a piece of information was previously transmitted, for emotional destinations (i.e., a happy or sad person) in Korsakoff's syndrome (KS). We asked patients with KS and control participants to tell facts to neutral, positive, or negative faces. On a subsequent recognition task, participants had to decide to whom they told each fact. Compared with control participants, patients with KS demonstrated lower recognition of neutral, emotionally positive, and emotionally negative destinations. Patients with KS demonstrated lower recognition of emotionally negative than for emotionally positive or neutral destinations, but there were no significant differences between recognition of neutral and emotionally positive destinations. Our study demonstrates a compromised ability to process negative destinations in KS. Our study highlights the relationship between memory decline and impaired emotional processing in KS.

Remembering to whom we transmit information during pandemics: the effect of face masks on destination memory

Considering the global pandemic we currently experience, face masks have become standard in our daily routine. Even though surgical masks are established as a safety measure against the dissemination of COVID-19, previous research showed that their wearing compromises face recognition. Consequently, the capacity to remember to whom we transmit information-destination memory-could also be compromised. In our study, through a between-participants design (experiment 1) and a within-participants design (experiment 2), undergraduate students have to transmit Portuguese proverbs to masked and unmasked celebrity faces. Following our hypothesis, participants who shared information with masked faces had worse destination memory performance than those who shared information with unmasked faces. Also, we observed lower recognition for masked faces compared to unmasked faces. These results were expected since using a surgical mask affects facial recognition, thus making it harder to recognize a person to whom information was previously transmitted. More importantly, these results also support the idea that variables associated with the recipient's face are important for destination memory performance.

Destination memory: Memory associated with social interactions

Within the field of memory research, studies on destination memory (e.g., the ability to remember to whom information was previously told) show how it is closely associated with social cognition. The present review thus summarizes the literature on destination memory and demonstrates how it involves social interaction. It offers a comprehensive picture of the many factors that may influence destination memory and distinguishes factors related to the recipient (e.g., familiarity, emotional states, and distinctiveness/attractiveness) and sender of information (e.g., the sender's extroversion) in social communications. It suggests that destination memory involves the ability of the sender to infer the cognitive/affective state of the recipient and to attribute the output message to a recipient-related stereotype. Extrovert senders may also easily remember the destination as they typically value social communication, public sharing and processing of social information. Destination memory also involves features such as familiarity, age, emotional state, distinctiveness, and attractiveness of the recipient. By offering a comprehensive framework of how destination memory functions in everyday life interactions, the present review shows how destination memory is intimately associated with communicative efficacy and social interactions.

Personality and social memory: High source and destination memory in extroverts

We evaluated relationship between personality and memory for social interactions. More specifically, we investigated the relationship between extraversion and the ability to remember who told us some information (i.e., source memory) and the ability to remember to whom we told that information (i.e., destination memory). On a source memory task, participants received information from pictures of celebrities; a subsequent recognition test required them to identify the celebrities from whom they had received that information. On a destination memory task, participants were invited to tell information to celebrities; a later recognition task instructed them to identify the celebrity to whom they had previously told that information. Besides the assessment of source and destination memory, participants answered a questionnaire regarding extraversion. Results demonstrated significant positive correlation between extraversion and source memory, as well as significant positive correlation between extraversion and destination memory. In other words, the more participants described themselves as extraverts, the higher their source and destination memory. During social communications (e.g., in a conversation), extraverts may demonstrate high source and destination memory as these individuals typically value social communication, public sharing, and processing of social information.

Unraveling the role of retrieval deficits in autobiographical memory impairment in schizophrenia: A comparison of involuntary and voluntary autobiographical memories

Patients with schizophrenia show severe autobiographical memory impairment, thought to reflect retrieval deficits caused by executive dysfunction. However, prior research has focused exclusively on strategic (voluntary) retrieval, and ignored involuntary retrieval resulting from automatic and associative processes, involving minimal cognitive control. We report two studies with patients diagnosed with schizophrenia (Ns = 40 and 50 respectively) comparing their impairment in involuntary versus voluntary autobiographical memory. We use two different methodologies, not previously used in schizophrenia research: a naturalistic study involving real-life data and an experimental setup. Both studies consistently showed that involuntary and voluntary autobiographical memories were similarly impaired in schizophrenia. The absence of interaction effects between group and retrieval suggests that schizophrenic patients did not benefit from memory tasks involving little retrieval effort. These findings suggest that autobiographical memory impairment in schizophrenia are not caused by problems with self-initiated voluntary retrieval, but instead likely reflect encoding or binding deficits.

Developmental trends in children's source and destination memory

Destination memory (the ability to remember who one has told information to) has been studied in adult samples, but not with child participants. The goals of the current research were to describe the development of children's destination memory abilities across early to middle childhood and to compare destination memory with source-monitoring abilities within the same age range. In two studies, children aged 5-10 years had conversations with two puppets and were later asked to recall which puppet they had disclosed specific information to. Study 1 (N = 86) revealed age to be a significant predictor of destination memory accuracy. Study 2 (N = 90) demonstrated that source memory and destination memory were related and shared a similar developmental trajectory but that source accuracy was higher on average than destination accuracy. This research contributes to our theoretical understanding of children's memory development, and directions for future research are highlighted in the Discussion. Implications for investigative interviews in which children are asked about prior disclosures are discussed.

Attractive memory: High destination memory for attractive faces

Research has demonstrated that destination memory (i.e., the ability to remember to whom information was previously told) can be influenced by characteristics (e.g., emotional expressions and age) of the destination. Building on this literature, we investigated whether destination memory can be influenced by the attractiveness of the destination. We invited participants to give information on attractive faces, unattractive faces, or neither-attractive-nor-unattractive faces. On a recognition test, they were invited to decide to whom each piece of information had been previously told. Results demonstrated higher destination memory (1) for attractive faces than for neither-attractive-nor-unattractive faces, and (2) for unattractive faces than for neither-attractive-nor-unattractive faces. We attribute the higher destination memory for attractive and unattractive destinations to their distinctiveness compared with neutrally attractive destinations. We also provide some attentional explanations for the high memory for attractive and unattractive destinations.

"To whom did I tell that information?": Relationship between destination memory and theory of mind in traumatic brain injury

Traumatic Brain Injury (TBI) has been widely associated with impairment of social cognition. We therefore investigated the relationship between the ability to infer and predict other's mental states (i.e., Theory of Mind, ToM) and the ability to remember to whom one has sent information (i.e., destination memory). We invited patients with TBI and control subjects, on a destination memory task, to tell proverbs to pictures of celebrities, so as to remember to which celebrity they had previously told the proverbs. Participants also performed affective (i.e., Reading the Mind in the Eyes) and cognitive (i.e., the false belief) tests of ToM. Results demonstrated lower destination memory, affective, and cognitive ToM performance in TBI patients than in control subjects. Critically, analysis demonstrated significant positive correlations between destination memory and first order and second cognitive order ToM in patients with TBI, but no significant correlations between destination memory and affective ToM in these patients. Our results demonstrate a relationship between difficulties of TBI patients to infer and predict cognitive states of interlocutors and difficulties to remember to which interlocutor information has been told.

The communicative function of destination memory

Mahr & Csibra's (M&C's) proposal that episodic memory has a role in communicative interaction is innovative. However, the model would be strengthened by the inclusion of the construct of destination memory. Destination memory refers to the ability to remember to whom one has sent information. Research has demonstrated that this ability is essential for communicative efficacy and daily interactions with others.

Memory and time: Backward and forward telescoping in Alzheimer's disease

Backward and forward telescoping are opposite timing biases. The former refers to misattributing events to earlier dates, whereas the latter refers to misattributing events to later dates. The present study investigated both biases in participants with Alzheimer's Disease (AD) and healthy older adults, matched on age, sex, and education level. Participants were asked to recall the years when five remote and five recent public events had occurred. They were also assessed with a cognitive and clinical battery that included a context memory task on which they had to associate letters and locations. Results showed backward telescoping for recent events and forward telescoping for remote events in AD participants and older adults. Furthermore, poorer context recall was observed in AD participants and older adults displaying backward telescoping than in those displaying forward telescoping. These findings suggest an association between the amount of contextual information recalled and the direction of the timing bias. Backward telescoping can be associated with deficiencies in retrieving context characteristics of events, which have been associated with retrograde amnesia and pathological changes to the hippocampus in AD.
