Events are temporally bounded experiences involving people, objects, and actions that can be segmented into sequences of smaller, meaningful events (e.g., steps involved in constructing a piece of furniture), but the role of inner language in remembering such events has been unclear. We investigated whether inner language enhances memory for events in a naturalistic, nonverbal task where participants constructed simple models from memory. Across three experiments, we used linguistic suppression in a dual-task paradigm to test whether inner language improved overall memory performance and completion time, additionally exploring the number of events that could be recalled. We found that access to inner language at encoding consistently affected memory performance: when inner language was disrupted at encoding, participants were poorer at recalling the models and remembered fewer events. This effect was present whether or not the number of events to be recalled exceed event memory capacity (estimated as approximately seven to eight events). Critically, linguistic suppression impaired memory performance to a greater extent than a control secondary task that did not affect access to language; that is, impairment was not solely due to dual-task interference. The results support the proposal that inner language enhances event memory via a mechanism of linguistic bootstrapping, which makes event representation more efficient by allowing more information to be encoded in an event model even when language is not being used in the task. These findings therefore extend theories of event memory and add to a growing body of evidence that inner language is a highly valuable cognitive tool.

Remembering past events usually takes less time than their actual duration-their unfolding is temporally compressed in episodic memory. The rate of temporal compression (i.e., the ratio of the actual duration of an event to the duration of its remembering) is not constant but varies between individuals and as a function of the structure of events (e.g., how they can be divided into shorter subevents). However, the cognitive mechanisms underlying these variations remain poorly understood. Given its role in the encoding and retrieval of information in episodic memory, working memory (WM) capacity could be an important determinant of temporal compression rates. We tested this hypothesis in two experiments in which we asked participants to watch and then mentally replay short videos showing people engaged in daily life activities. We showed that temporal compression rates depend on an interplay between WM and the structure of the remembered events: participants' WM capacity (assessed using complex span tasks) was negatively associated with temporal compression rates, but only when the remembered events contained few event boundaries (i.e., few subevents). This suggests that the temporal compression of events in episodic memory emerges when some of the subevents to be retained are too long to be fully represented in WM.

Relations between conative factors (task-specific motivation, attention self-efficacy, and self-set goals) and individual differences in attention control (AC) performance were investigated in two latent variable studies. Participants performed AC tasks along with measures of working memory and processing speed. During the AC tasks, participants self-reported their motivation, self-efficacy, and self-set goals for the tasks. Task-unrelated thoughts were also assessed. Confirmatory factor analyses demonstrated that latent factors for the constructs could be formed and the conative factors were each related to the AC factor. Structural equation modeling further suggested that the conative factors tended to account for unique variance in attention, even after accounting for shared variance with working memory and processing speed. These results provide evidence that conative factors are important for individual differences in AC and further suggest that multiple factors likely contribute to variation in performance on AC tasks.

Infants' early words tend to be phonologically similar. This may reflect a systematic approach to early production, as they adapt newly acquired forms to fit familiar structures in the output. This "rich-get-richer" approach to phonological acquisition, known as preferential attachment in network science, proposes that new words cluster together with existing phonologically similar words in the lexicon (or network). This contrasts with recent work (e.g., Fourtassi et al., 2020) showing that the learning environment is the key predictor of learning (preferential acquisition). This study expands on previous analyses of vocabulary norm data to analyze naturalistic data, namely phonetic transcriptions of nine infants' word productions, from word onset to age 2;6. Network growth models test whether (a) acquisition is best modeled through preferential attachment or preferential acquisition, (b) the trajectory of network growth changes over time, and (c) there are any differences in network growth of adult target forms versus infants' actual productions. Results show that preferential attachment predicts acquisition of new words more convincingly than preferential acquisition: newly acquired words are phonologically similar to existing words in the network. Furthermore, systematicity becomes increasingly apparent over the course of acquisition, and infants produce their early words more systematically than we would expect from looking at target forms alone.

The construct of mind wandering has notoriously been characterized as heterogenous which may mean that not all types of mind wandering produce the same pattern of results. One operationalization of mind wandering, task-unrelated thoughts (TUTs), can also itself vary in many dimensions, including the emotional valence of TUTs. The current study summarizes several years of work examining the impact that the emotional valence of TUTs has on different aspects of sustained attention. Participants in several studies reported whether their TUTs were negative, neutral, or positive in emotional valence during a sustained attention-to-response task (SART). The first major focus was a meta-analysis where we examined correlations between each TUT valence and SART performance measures. For the second major focus, we tested how different TUT valences changed over the course of the task. The results suggest that negative TUTs typically show stronger associations with SART performance measures, although all TUT valences have numerically similar correlations. Regarding time-on-task effects, across the studies, there was consistent evidence for a linear increase in negative TUTs across blocks. Evidence for this linear increase was not consistent for neutral and positive TUTs. The results of the current study suggest that the relationships between TUTs and performance, and their likelihood of occurring during a task, are not necessarily the same for every type of TUT. These results highlight the importance of continuing to investigate different types of TUTs and different forms of mind wandering, in general, to better understand how this phenomenon occurs.

Cross-situational word learning (CSWL), the ability to resolve word-referent ambiguity across encounters, is a powerful mechanism found in infants, children, and adults. Yet, we know little about what predicts individual differences in CSWL, especially when learning different mapping structures, such as when referents have a single name (1:1 mapping structure) or two names (2:1 mapping structure). Here, we investigated how multilingual experience and working memory skills (visuo-spatial and phonological) contributed to CSWL of 1:1 and 2:1 structures. Monolingual (n = 78) and multilingual (n = 106) adults completed CSWL tasks of 1:1 and 2:1 structures, a symmetry span task, and a listening span task. Results from path models showed that multilingualism predicted visuo-spatial working memory but not CSWL. Additionally, phonological working memory predicted accuracy on CSWL of 1:1 structure, but not 2:1 structure. Findings highlight the importance of considering language experience and cognitive skills together to better understand the factors that promote individual CSWL skills.

In an influential article, Jones et al. (1995) provide evidence that auditory distraction by changing relative to repetitive auditory distracters (the changing-state effect) did not differ between a visual-verbal and visual-spatial serial recall task, providing evidence for an amodal mechanism for the representation of serial order in short-term memory that transcends modalities. This finding has been highly influential for theories of short-term memory and auditory distraction. However, evidence vis-à-vis the robustness of this result is sorely lacking. Here, two high-powered replications of Jones et al.'s (1995) crucial Experiment 4 were undertaken. In the first partial replication (n = 64), a fully within-participants design was adopted, wherein participants undertook both the visual-verbal and visual-spatial serial recall tasks under different irrelevant sound conditions, without a retention period. The second near-identical replication (n = 128), incorporated a retention period and implemented the task-modality manipulation as a between-participants factor, as per the original Jones et al. (1995; Experiment 4) study. In both experiments, the changing-state effect was observed for visual-verbal serial recall but not for visual-spatial serial recall. The results are consistent with modular and interference-based accounts of distraction and challenge some aspects of functional equivalence accounts.

The learned predictiveness effect refers to the tendency for predictive cues to attract greater attention and show faster learning in subsequent tasks. However, in typical designs, the predictiveness of each cue (its objective cue-outcome correlation) is confounded with the degree to which it is informative for making the correct response on each trial (a feature we term choice relevance). In four experiments, we tested the unique contributions of cue-outcome correlation and choice relevance to the learned predictiveness effect by manipulating the outcome choices available on each trial. Experiments 1A and 1B compared two sets of partially predictive cues and found that participants learned more in a transfer phase about the set of cues that were previously choice-relevant. Experiments 2A and 2B used a design in which the cue-outcome correlation was stronger for one set of cues (perfect predictors) than the other set (imperfect predictors). Manipulating the choice relevance of the imperfect predictors in this design did not influence the magnitude of the learning bias toward the perfect predictor. Unlike cue-outcome correlation, choice relevance did not seem to correspond to biases in eye-gaze, suggesting that it operates via a distinct mechanism. Simulations with a modified EXIT model successfully predicted cue-outcome correlation and choice relevance effects by assuming that participants update learning for present outcomes only, but incorrectly predicted additive effects. We conclude that cue-outcome correlation and choice relevance are important factors that can lead to biases in future learning; both were individually sufficient but neither was necessary.

Temporal discounting refers to the tendency to discount future rewards as a function of time until receipt of rewards. The discount rate can be reduced by experimentally manipulating time framing, an example being the date/delay effect: Specifically, if time until receipt of the reward is presented as a date (e.g., August 21, 2022) rather than as a delay (e.g., 136 days), temporal discounting is reduced. While this effect has been replicated several times, its underlying cognitive mechanisms are not well understood. Therefore, we used eye tracking to examine the role of attention in the date/delay effect. Participants completed both a delay and date condition of the Monetary Choice Questionnaire, while eye movements were recorded (N = 54). Results revealed a successful replication of the date/delay effect (p < .001, g_av = 0.48). Eye tracking showed that participants compared time attributes (relative to reward attributes) more and fixated them longer in the date compared to the delay condition. Moreover, the absolute difference in reward values of choice options was more predictive of choosing the delayed reward in the date compared to the delay condition. Finally, explorative correlations revealed a stronger date/delay effect in participants who paid more attention to time than reward attributes in the delay condition and who used a more integrative search strategy. Our findings suggest that the date manipulation causes participants to weight rewards more strongly in their decision process than in the delay condition, ultimately reducing temporal discounting. Computation of time intervals in the date condition could possibly reflect an adaptation lowering the date/delay effect. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

It has been repeatedly shown that individuals track speaker-specific language use during interaction. Most studies focused on how this facilitates meaning inference when interspeaker variation differentiates between two or more alternatives, or how it allows for successful lexical alignment. However, it has been unclear whether mapping interspeaker variation is stored actively, and if so, what purposes this storage serves. In a pseudointeractive experiment, we created interspeaker variation in naming preferences, such that one speaker (the common speaker) consistently produced favored words, and the other speaker consistently produced less-favored/disfavored words (the uncommon speaker), across two conditions-one where both speakers were relatively common, and one where one of the speakers was highly uncommon. Participants engaged in a picture selection task, at first as matchers (where they were instructed by one of the speakers-each in his/her turn-which image to choose), and then as directors (where they were the instructors). They were then tested on how well they mapped interspeaker variation and how they generalized it linguistically and socially. Participants were successful at directly mapping interspeaker variation in naming preferences. Furthermore, they used this information in (a) lexically aligning with their interlocutors, (b) hypothesizing about unexposed word choices by these speakers, and (c) creating social representations of the speakers as individuals. In line with surprisal-driven learning accounts, these effects were larger for a speaker that used highly uncommon words. Our results suggest that individuals store interspeaker variation explicitly, which in turn helps them to predict their interlocutors' future linguistic and social behavior.
