RESUMO
People are often presented with large amounts of information to remember, and in many cases, the font size of information may be indicative of its importance (such as headlines or warnings). In the present study, we examined how learners perceive the importance of information in different font sizes and how beliefs about font size influence selective memory. In Experiment 1, participants were presented with to-be-remembered words that were either unrelated or related to a goal (e.g., items for a camping trip) in either small or large font. Participants rated words in large font as more important to remember than words in small font when the words in a list were unrelated but not when the words were schematically related to a goal. In Experiments 2 and 3, we were interested in how learners' belief that font size is indicative of importance translates to their ability to selectively encode and recall valuable information. Specifically, we presented participants with words in various font sizes, and larger fonts either corresponded to greater point values or smaller point values (values counted towards participants' scores if recalled). When larger fonts corresponded with greater point values, participants were better able to selectively remember high-value words relative to low-value words. Thus, when to-be-remembered information varies in value, font size may be less diagnostic of an item's importance (the item's importance drives memory), and when the value of information is consistent with a learner's belief, learners can better engage in selective memory.
RESUMO
Predictions about memory involve the use of metacognition, and metacognition can rely on various cues. The present study investigated metacognition and recall performance when to-be-remembered words differed in font size and emotional valence, to determine what cues are utilised when making metacognitive judgments. Participants were presented with lists of words varying in font size (small and large) and emotional valence (negative and neutral) and were asked to remember as many words as possible for a later recall test while engaging in item-level metacognitive assessments. Specifically, after studying each word, participants either made only judgments of learning (JOLs, Experiment 1) or both JOLs and restudy judgments (Experiment 2). Across experiments, results revealed that while JOLs were sensitive to both font size and emotional valence, restudy judgments were mostly sensitive to emotional valence, and participants' metacognitive assessments mapped onto memory performance generally for emotional words. Additionally, we found that the effect of font size on metacognition and memory was robust to experience-based learning. Together, the current study extends our understanding of how emotion and font size affect metacognition (monitoring and control) and memory and suggests that when presented with multiple cues, certain diagnostic cues can be harnessed to mitigate metacognitive illusions.

We examined the effects of interference on value-based memory in younger and older adults by presenting participants with lists of words paired with point values counting toward their score if recalled. In Experiment 1, we created a situation where there was a buildup of interference such that participants could recall words from any studied list to earn points. However, to increase participants' motivation to combat interference, we told participants that if they recalled words from previously studied lists, those words would be worth double the original point value of the word. In Experiment 2, to examine age-related differences in the absence of any interference, participants studied and were tested on the same set of words throughout several study-test cycles. The buildup of interference caused by participants needing to recall both just-studied and previously studied words in Experiment 1 impaired selectivity in older adults relative to younger adults and this effect was particularly pronounced when considering the recall of just prior-list words. However, in the absence of interference, there was not an overall recall deficit or any selectivity impairments in older adults. Thus, proactive and retroactive interference seem to be largely responsible for age-related deficits in selective memory for important information.

The ability to prioritize valuable information is critical for the efficient use of memory in daily life. When information is important, we engage more effective encoding mechanisms that can better support retrieval. Here, we describe a dual-mechanism framework of value-directed remembering in which both strategic and automatic processes lead to differential encoding of valuable information. Strategic processes rely on metacognitive awareness of effective deep encoding strategies that allow younger and healthy older adults to selectively remember important information. In contrast, some high-value information may also be encoded automatically in the absence of intention to remember, but this may be more impaired in older age. These different mechanisms are subserved by different neural substrates, with left-hemisphere semantic processing regions active during the strategic encoding of high-value items, and automatic enhancement of encoding of high-value items may be supported by activation of midbrain dopaminergic projections to the hippocampal region.

We are frequently exposed to situations where we need to remember important information when our attentional resources are divided; however, it was previously unclear how divided attention impacts responsible remembering: selective memory for important information to avoid consequences for forgetting. In the present study, we examined participants' memory for valuable information, metacognitive accuracy, and goal-directed cognitive control mechanisms when under full and divided attention. In Experiment 1, participants were presented with words paired with point values counting towards their score if recalled but were required to "bet" on whether they would remember it. Results revealed that selective memory for high-value information was impaired under divided attention. In Experiment 2, we presented participants with unassociated word pairs and solicited metacognitive predictions of recall (i.e., JOLs). Results revealed that the relative accuracy of participants' metacognitive judgments was enhanced when studying under divided attention. Experiment 3 examined cognitive control mechanisms to selectively remember goal-relevant information at the expense of information that could potentially be offloaded (i.e., responsible forgetting). Results revealed that participants' ability to strategically prioritize goal-relevant information at the expense of information that could be offloaded was preserved under divided attention. Collectively, responsible attention encompasses how attentional resources impact one's ability to engage in responsible remembering and we demonstrate that responsible remembering can be impaired, enhanced, and preserved in certain contexts.

When learning, it is often necessary to identify important themes to organize key concepts into categories. In value-directed remembering tasks, words are paired with point values to communicate item importance, and participants prioritize high-value words over low-value words, demonstrating selective memory. In the present study, we paired values with words based on category membership to examine whether being selective in this task would lead to a transfer of learning of the "schematic reward structure" of the lists with task experience. Participants studied lists of words paired with numeric values corresponding to the categories the words belonged to and were asked to assign a value to novel exemplars from the studied categories on a final test. In Experiment 1, instructions about the schematic structure of the lists were manipulated between participants to either explicitly inform participants about the list categories or to offer more general instructions about item importance. The presence of a visible value cue during encoding was also manipulated between participants such that participants either studied the words paired with visible value cues or studied them alone. Results revealed a benefit of both explicit schema instructions and visible value cues for learning, and this persisted even after a short delay. In Experiment 2, participants had fewer study trials and received no instructions about the schematic structure of the lists. Results showed that participants could learn the schematic reward structure with fewer study trials, and value cues enhanced adaptation to new themes with task experience.

Metacognition involves the understanding and awareness of one's cognitive processes, and responsible remembering is the notion that people strategically focus on and remember important information to prevent negative consequences for forgetting. The present study examined the metacognitive control processes involved in responsible remembering by evaluating how information importance affects one's allocation of study time and subsequent recall. Specifically, participants were presented with pictures of children along with each child's food preferences (2 foods they like, 2 foods they dislike, and 2 foods they are allergic to and must avoid) to remember for a later test. When making no metacognitive assessments or judging the likelihood of later remembering each food preference (JOL), participants did not strategically study or demonstrate enhanced recall for the most important information (allergies). However, when making judgments of importance (at either the item or global level), participants spent more time studying and best recalled the information that they rated as most important to remember (allergies). Collectively, these results suggest that when people judge the importance of remembering information, whether at the global or item level, study decisions are better informed, resulting in strategic studying and greater recall for information with the most severe consequences for forgetting.

Prior work has demonstrated that watching videos at faster speeds does not significantly impair learning in younger adults; however, it was previously unclear how increased video speed impacts memory in older adults. Additionally, we investigated the effects of increased video speed on mind-wandering. We presented younger and older adults with a pre-recorded video lecture and manipulated the video to play at different speeds. After watching the video, participants predicted their performance on a memory test covering the material from the video and then completed said memory test. We demonstrated that although younger adults can watch lecture videos at faster speeds without significant deficits in memory, older adults' test performance is generally impaired when watching at faster speeds. Additionally, faster playback speeds seem to reduce mind-wandering (and mind-wandering was generally reduced in older adults relative to younger adults), potentially contributing to younger adults' preserved memory at faster speeds. Thus, while younger adults can watch videos at faster speeds without significant consequences, we advise against older adults watching at faster speeds.

RESUMO
We examined whether framing younger and older adults learning goals in terms of maximizing gains or minimizing losses impacts their ability to selectively remember high-value information. Specifically, we presented younger and older adults with lists of words paired with point values and participants were either told that they would receive the value associated with each word if they recalled it on a test or that they would lose the points associated with each word if they failed to recall it on the test. We also asked participants to predict the likelihood of recalling each word to determine if younger and older adults were metacognitively aware of any potential framing effects. Results revealed that older adults expected to be more selective when their goals were framed in terms of losses, but younger adults expected to be more selective when their goals were framed in terms of gains. However, this was not the case as both younger and older adults were more selective for high-value information when their goals were framed in terms of maximizing gains compared with minimizing losses. Thus, the framing of learning goals can impact metacognitive decisions and subsequent memory in both younger and older adults.
RESUMO
Older adults experience deficits in associative memory. However, age-related differences are reduced when information is consistent with prior knowledge (i.e., schematic support), suggesting that episodic and semantic memory are interrelated. It is unclear what role metacognitive processes play in schematic support. Prior knowledge may reduce encoding demands, but older adults may allocate cognitive resources to schema-consistent information because it is more meaningful. We examined metacognitive awareness of and control over associative information that was consistent or inconsistent with prior knowledge. In Experiment 1, participants self-paced their study of grocery items paired with either market prices or unusually high prices and were tested on the exact price of each item over four study-test lists with new items on each list. In Experiment 2, participants studied items for a fixed time but made judgments of learning (JOLs) at encoding. Older adults better remembered the prices of market-value items than overpriced items. In Experiment 1, younger and older adults studied overpriced items longer than market-priced items, consistent with a discrepancy reduction model of self-regulated learning, but study time did not relate to later recall accuracy, suggesting a labor-in-vain effect. In Experiment 2, participants gave higher JOLs to market-priced items than overpriced items and were generally metacognitively aware of the benefits of schematic support. Together, these results suggest that the benefits of schematic support may not be dependent on or influenced by metacognitive control processes, supporting the hypothesis that episodic memory may be less distinct from semantic memory in younger and older adults.

Serial position effects involve the differential recall of information based on its temporal order at encoding. Previous research indicates that learners may be aware of these effects under certain encoding conditions, but it is unclear whether metacognitive control is sensitive to serial position effects. The current study examined whether there are serial position effects in participants' study time and whether they can learn about serial position effects under fixed encoding conditions and then transfer what they have learned to self-paced study conditions. Specifically, participants were given lists of to-be-remembered words and studied each word for a fixed duration on initial lists, but self-paced their study time on later lists. Results revealed that self-paced study times oppositely mirrored serial position effects (i.e., briefer study times in the beginning and end of each list), and serial position effects were reduced in self-paced study conditions, particularly in participants initially studying under fixed conditions before self-pacing their study time. Specifically, participants may have monitored their output and, based on observations of forgetting middle items, transferred their learning of serial position effects from prior lists. Thus, participants may use forgetting and serial position information to guide encoding, indicating that fundamental properties of the memory system can be incorporated into the processes that guide metacognitive control.

Do the properties of to-be-remembered events influence the ability to remember, and also intentionally forget, these events in similar ways? Prior work has examined how the font size, animacy, emotionality, concreteness (the degree to which a word denotes something perceptible), frequency (how often a word appears in language), and length of to-be-remembered words influence memory. However, it was previously unclear whether the forgetting of information is also influenced by these characteristics. In six experiments, we used an item-method directed forgetting task where we presented participants with to-be-remembered and to-be-forgotten words varying in font size (large or small), animacy (animate or inanimate), emotionality (negative or neutral), concreteness (high or low), frequency (high or low), and word length (long or short). Results revealed that animacy, emotionality, concreteness, frequency, and word length (but not font size) influenced both remembering and forgetting. Together, the present findings indicate that the characteristics of presented words can influence remembering as well as directed forgetting, providing further evidence that the remembering and forgetting processes are governed by similar properties.

ABSTRACTPeople tend to better remember same-race faces relative to other-race faces (an "own-race" bias). We examined whether the own-race bias extends to associative memory, particularly in the identification and recall of information paired with faces. In Experiment 1, we presented white participants with own- and other-race faces which either appeared alone or accompanied by a label indicating whether the face was a "criminal" or a "victim". Results revealed an own-race facial recognition advantage regardless of the presence of associative information. In Experiment 2, we again paired same- and other-race faces with either "criminal" or "victim" labels, but rather than a recognition test, participants were asked to identify whether each face had been presented as a criminal or a victim. White criminals were better categorised than Black criminals, but race did not influence the categorisation of victims. In Experiment 3, white participants were presented with same- and other-race faces and asked to remember where the person was from, their occupation, and a crime they committed. Results revealed a recall advantage for the associative information paired with same-race faces. Collectively, these findings suggest that the own-race bias extends to the categorisation and recall of information in associative memory.

Although older adults are often concerned about instances of forgetting, forgetting can be a useful feature of our memory system. Specifically, strategically forgetting less important information can benefit memory for goal-relevant information (i.e., responsible remembering and responsible forgetting). In two experiments, we presented younger and older adults with a list of words (either unrelated words or items to bring on a camping trip) with a cue indicating whether participants ("You") or their "Friend" was responsible for remembering each item. Results revealed that both younger and older adults engaged in responsible remembering and forgetting by better remembering items they were responsible for remembering, indicating a strategic utilization of their limited memory capacity. Additionally, regardless of age and the cue indicating who was responsible for remembering each item, participants used importance to guide the encoding and retrieval of information. Thus, people may be able to engage strategic cognitive mechanisms to maximize memory utility for important, goal-relevant information, and responsible forgetting can enhance memory utility in both younger and older adults by using importance to drive memory and reduce consequences for forgetting.

The ability to control both what we remember and what is forgotten can enhance memory. The present study used an item-method directed forgetting paradigm to investigate whether participants strategically remembered items they were responsible for remembering rather than items a hypothetical friend was responsible for remembering. Specifically, participants were presented with a 20-word list (either unrelated words or items to pack for a camping trip) with each word followed by a cue indicating whether the participant (You) or their "friend" (Friend) was responsible for remembering the word. When asked to recall all of the words, regardless of the cue, recall was sensitive to the You and Friend instructions such that participants demonstrated elevated recall for the items they were responsible for remembering, and participants also strategically organized retrieval by recalling You items before Friend items. Additionally, when asked to judge the importance of remembering each item, participants' recall and recognition were sensitive to item importance regardless of cue. Taken together, the present experiments revealed that the strategic encoding of important information and the forgetting of less important, goal-irrelevant information can maximize memory utility and minimize negative consequences for forgetting. Thus, we provide evidence for a metacognitive process we are calling responsible forgetting, where people attempt to forget less consequential information and focus on remembering what is most important.

Given natural memory limitations, people can generally attend to and remember high-value over low-value information even when cognitive resources are depleted in older age and under divided attention during encoding, representing an important form of cognitive control. In the current study, we examined whether tasks requiring overlapping processing resources may impair the ability to selectively encode information in dual-task conditions. Participants in the divided-attention conditions of Experiment 1 completed auditory tone-distractor tasks that required them to discriminate between tones of different pitches (audio-nonspatial) or auditory channels (audio-spatial), while studying items in different locations in a grid (visual-spatial) differing in reward value. Results indicated that, while reducing overall memory accuracy, neither cross-modal auditory distractor task influenced participants' ability to selectively encode high-value items relative to a full attention condition, suggesting maintained cognitive control. Participants in Experiment 2 studied the same important visual-spatial information while completing demanding color (visual-nonspatial) or pattern (visual-spatial) discrimination tasks during study. While the cross-modal visual-nonspatial task did not influence memory selectivity, the intra-modal visual-spatial secondary task eliminated participants' sensitivity to item value. These results add novel evidence of conditions of impaired cognitive control, suggesting that the effectiveness of top-down, selective encoding processes is attenuated when concurrent tasks rely on overlapping processing resources.

ABSTRACTSerial position effects are often observed within the free recall of unassociated words but also when recalling items from a semantic category like U.S. presidents. We investigated the dynamics of recall for U.S. presidents in younger and older adults to examine potential age-related differences in the organisation of retrieval from semantic long-term memory. Older adults recalled more presidents than younger adults and also demonstrated dual serial position effects such that, in addition to overall serial position effects, primacy (e.g., Eisenhower) and recency presidents (e.g., Obama) within older adults' lifetime were better recalled than presidents from the middle of their lives (e.g., Ford). Additionally, participants initiated recall with the most distinct presidents (highly familiar or memorable presidents like Washington, Obama, Trump), and conditional-response probabilities revealed that presidents from similar eras were recalled in close proximity, indicating that the retrieval of distinct presidents can facilitate memory for presidents from a similar era. Collectively, we demonstrate the potential interplay of the mechanisms that influence the organisation of retrieval such that distinctiveness and temporal contiguity effects may simultaneously impact recall. Specifically, semantic and temporal-contextual associations can drive semantic autobiographical memory and people likely organise retrieval from long-term memory according to familiarity and distinctiveness.

Adaptive memory refers to the memory advantage for information processed in a survival and/or reproduction context while metacognition involves the awareness of what we can later remember. The notion of "responsible remembering" captures how memory functions to prioritise important information that will need to be remembered and how metacognitive processes may be more precise in situations involving consequences for forgetting. In 5 experiments, we examined whether judgments of learning and judgments of importance affect recall selectivity for information with negative consequences if forgotten. We presented participants with lists of children, each with 2 foods they like, 2 foods they dislike, and 2 foods they are allergic to. When making no metacognitive judgments or making JOLs for each food preference, participants best recalled foods the children liked, likely resulting from serial remembering (recalling information according to where it was presented). However, when judging the importance of remembering items, participants were strategic in their memory for the food preferences such that they best recalled information they rated as important to remember (allergies). These results suggest that when forced to consider the importance of remembering, participants engage in responsible remembering by deeming information with consequences for forgetting as most important and subsequently best remembering this information.

People often need to remember the location of important objects or events, and also to remember locations that are associated with negative objects. In the current study, we examined how both positive and negative items might be selectively remembered in the visuospatial domain. Participants studied number-items ranging from -25 to +25 indicating point values in a grid display and were instructed to maximize their score (a summation of correctly remembered positive and negative information; incorrectly placed negative items resulted in a subtraction from the overall score). Items were presented in a sequential, simultaneous (Experiment 1), or self-regulated format (Experiment 2) where participants controlled which items to study and the length of study time per item. In Experiment 1, participants selectively recalled high-magnitude over low-magnitude items, but also displayed a positivity preference in memory. In Experiment 2, we were able to determine whether this positivity preference was a result of bottom-up, automatic, or top-down strategic processes. Results indicated that participants explicitly chose to study positive items more frequently and for more total time relative to negative items, suggesting a deliberate strategy to focus on positive information. This bias for highly positive information suggests an overt points-gained approach, as opposed to a loss-aversion approach, to remembering value in the visuospatial domain.
