We investigated the effect of semantic information on word memory, using imageability and sensorimotor strength as predictors, with data from a mega-study of word recognition memory (Cortese et al., 2010; 2015), as well as from an online memory task. Memory performance was analysed in hierarchical linear regressions. Both sensorimotor strength and imageability had an effect on word memory performance, but not as strong as reported in previous literature. However, the effects were smaller when the memory task was unexpected, suggesting that the semantic effects are dependent on memory strategies (or context). Most importantly, different types of sensorimotor strength had a variable effect on memory, which was not in line with the prediction of the semantic richness effect, and highlighted the importance of a multi-dimensional approach to measuring and testing semantic experience, and its effect on cognitive processing. The findings have implications for the use of semantic variables in memory research.

More is not necessarily better – how different aspects of sensorimotor experience affect recognition memory for words

EMNLP 2021 is planned to be a hybrid event in Punta Cana, Dominican Republic, with both on-site and fully virtual participation possible. The experience for on-site participants would closely approximate a normal pre-COVID *ACL conference, with 5-6 thematically organized parallel sessions and live Q/A and interactive discussion immediately after the talks. Presentations by virtual participants will be equitably interleaved with those of on-site participants, projected on the auditorium screens as if on-site, and also followed immediately by live Q/A and interactive discussion at a time during reasonable waking hours for the virtual presenter. For all participants, on-site and virtual, who are unable to attend a session due to either time-zone issues or because they are participating in another session live, talk recordings and slides will be available online at a minimum after the live presentation (and in many cases before as well), and questions may be submitted in advance on session-specific discussion boards and answered live in session with the usual visual aids if desired.

The Cognitive Science Society brings together researchers from around the world who hold a common goal: understanding the nature of the human mind. The mission of the Society is to promote Cognitive Science as a discipline, and to foster scientific interchange among researchers in various areas of study, including Artificial Intelligence, Linguistics, Anthropology, Psychology, Neuroscience, Philosophy, and Education. The Society is a non-profit professional organization and its activities include sponsoring an annual conference and publishing the journals Cognitive Science and TopiCS.

Beliefs have long been posited to be a predictor of behavior. However, empirical investigations into the relationship between beliefs (e.g., “vaccines cause autism”) and behaviors (e.g., vaccinating one’s child), mostly correlational in nature, have provided conflicting findings. To explore the causal impact of beliefs on behaviors, participants first rated the accuracy of a set of statements (health-related in Study 1, politically-charged in Studies 2 and 3) and chose corresponding campaigns to donate available funds. They were then provided with relevant evidence in favor of the correct statements and against the incorrect statements. Finally, participants rated the accuracy of the initial set of statements again and were given a chance to change their donation choices. The results of all three studies show that belief change predicts behavioral change, finding of particular relevance for interventions aimed at promoting constructive behaviors such as recycling, donating to charity, or employing preventative health measures.

Belief Change Triggers Behavioral Change

Deese/Roediger/McDermott (DRM) list words can share either semantic relatedness or phonological resemblance with their critical distractor. We review three lines of evidence in which semantic and phonological DRM illusions have been compared: (a) studies in which the two illusions were tracked in populations with different semantic or surface memory abilities; (b) studies that investigated the effects of manipulations that target semantic content or surface content or both; and (c) studies that examined hybrid forms of the illusion in which there was both semantic and surface resemblance between false memories and actual experiences. The three lines of evidence showed that semantic and phonological DRM illusions display dissociative patterns in most instances, indicating that they are two distinct types of false memories. We also discussed how the two major theories of the DRM illusion, fuzzy-trace theory and the activation/monitoring framework, account for the underlying mechanisms for the semantic and phonological illusions.

Semantic and Phonological False Memory: A Review of Theory and Data

A critically understudied aspect of team adaptation is the phenomenon of coordination breakdowns (CBs). CBs are characterized by a temporarily diminished ability to function effectively as a team. However, team research currently lacks robust methods for identifying and anticipating when teams transition from functioning effectively to a CB. With the current study, we aim to deepen our understanding of how team coordination dynamics across various interaction modalities reflect CBs and effective teamwork, utilizing a three-pronged research approach. First, we used audiovisual data from four person teams involved in a stressful collaborative game task to manually identify CBs. Second, we applied team coordination dynamics measures to physiological and speech data obtained during the task to computationally identify CBs. Third, the latter output was used as input for transition anticipation methods, generating computationally anticipated CBs. Our findings contribute theoretically and methodologically to the systematic investigation of CBs.

A systematic investigation into team coordination breakdowns

We asked whether it is possible to simultaneously activate two timelines in the human mind. We hypothesized that the lateral (left-right) and sagittal (back-front) spatial dimensions can be coactivated and expected the congruent space-time mappings of each dimension (back-past front-future and left-past right-future), but not the non-coherent ones, to prime each other. Participants were asked to keep in mind the two spatial dimensions as discrete entities. Spanish speakers categorized the temporal reference of sentences by pressing a sagittal directional key with their left or right hand. Results suggest that (i) full congruence facilitates the spatial representation of time the most, (ii) full incongruence interferes the most with the spatial representation of time, and (iii)
the two partial forms of congruence produce similar interference effects between the two spatial dimensions and time. The results were interpreted according to the Coherent Working Models approach.

Do left-right and back-front mental timelines activate simultaneously?

There is broad empirical evidence suggesting that higher-level cognitive processes, such as language, categorization, and emotion, shape human visual perception. For example, categories that we acquire throughout lifetime have been found to alter our perceptual discriminations and distort perceptual processing. Here, we study categorical effects on perception by adapting the perceptual matching task to minimize the potential non-perceptual influences on the results. We found that the learned category-color associations bias human color matching judgments away from their category ideal on a color continuum. This effect, however, unequally biased two objects (probe and manipulator) that were simultaneously present on the screen, thus demonstrating a more nuanced picture of top-down influences on perception than has been assumed both by the theories of categorical perception and the El Greco methodological fallacy. We suggest that only the concurrent memory for visually present objects is subject to a contrast-from-caricature distortion due to category-association learning.

Categories affect color perception of only some simultaneously present objects

Dividing attention by loading working memory is an effective method of probing the declarative and procedural underpinnings of linguistic knowledge. The current study explores WM/DA effects on four specific L2 domains: morphology (aspect versus case), syntax and semantics (collocations). We contrast performance of 68 learners of Polish as a foreign language (L1 Chinese) in a grammaticality judgement task in baseline and divided attention conditions. We found corroborating evidence for heightened dependency on declarative memory in early (A2) L2 learners across all linguistic categories and in both experimental conditions. While the lexical judgement of more advanced (B1) learners also proved vulnerable to secondary-task interference, introduction of additional cognitive load had a positive effect on participants’ grammatical judgement, yielding more accurate responses in the aspect category. These results point towards the need for pursuing a new line of inquiry into a potentially facilitative role of cognitive load on L2 learners’ grammatical processing.

The ‘know-what’ and the ‘know-how’: importance of declarative and procedural memory systems in the L2 learning of morphology, syntax and semantics

We propose an interaction in expectation formation between returns of an investment and the favorability of new information.
Such an interaction can have consequences in trading behavior like leading to the Disposition Effect or differences in the profitability of selling and buying decisions.
We introduce a context sensitive Reinforcement Learning model to capture this effect and validate it in a pre-registered investment experiment.
Using a Bayesian Hierarchical model fitting approach we find the interaction to stem mainly from participants incorporating unfavorable information more strongly when in a gain position and less so when in a loss.
By providing increasing levels of additional information about the price movements we are able to mitigate these effects in a second phase of the experiment.
Speaking for a strong effect of belief formation, very clear information is needed to mitigate the observed averse belief and investment patterns.

The Effect of Investment Position on Belief Formation and Trading Behavior

Memory is reliably enhanced for information read aloud compared with information read silently—this is known as the production effect. Theoretical accounts of this effect have been largely verbal in nature with very little exception, yet its robustness (and that of related phenomena) suggests that it is worth integrating into existing computational approaches to memory. A leading account of the production effect proposes that production leads to encoding of additional features at study and that these features are available at test to assist retrieval, conferring the observed memory benefit. We implement a version of this account into the Retrieving Effectively from Memory (REM) computational framework and examine its ability to capture key phenomena associated with the production effect. We compare and contrast the current implementation in REM with a pre-existing implementation of this effect in MINERVA2, in addition to discussing alternative conceptualizations and future work.

Modelling the production effect in recognition memory

Many models of cognition assume that people can generate independent samples, yet people fail to do so in random generation tasks. One prominent explanation for this behavior is that people use learned schemas. Instead, we propose that deviations from randomness arise from people sampling locally rather than independently. To test these explanations, we teach people one- and two-dimensional arrangements of syllables and ask them to generate random sequences from them. Although our results reproduce characteristic features of human random generation, such as a preference for adjacent items and an avoidance of repetitions, we also find an effect of dimensionality on the patterns people produce. Furthermore, model comparisons revealed that local sampling accounted better for participants' sequences than a schema account. Finally, evaluating the importance of each models' constituents, we show that the local sampling model proposed new states based on its current trajectory, rather than an inhibition-of-return-like principle.

Local Sampling with Momentum Accounts for Human Random Sequence Generation

Understanding how we judge effortfulness promises insight into the myriad choices we make each day. Here, we present research investigating a curious finding: In Dunn et al., 2019, individuals anticipated reading a single rotated word as more effortful than reading two upright words. This contravenes the expectation that the latter will take significantly longer. In Dunn et al. (2019) participants had limited experience engaging in the task beyond judging anticipated effort. In the present investigation participants performed demand selection and forced-choice tasks for which they read either one rotated or two upright words. We analyze results in terms of choice, accuracy, vocal onset time, and task duration. Participants still generally considered reading two words as less effortful (and preferable) to one rotated word but, interestingly, this tendency diminished as the task wore on. We discuss implications for understanding individuals’ effort-based choices.
