A commonly held assumption is that demonstration and pantomime differ from
ordinary action in that the movements are slowed down and exaggerated to be better
understood by intended receivers. This claim has, however, been based on meager
empirical support. This article provides evidence that different
functional demands of demonstration and pantomime result in motion characteristics
that differ from those for praxic action. In the experiment, participants were dressed
in motion capture suits and asked to (1) perform an action, (2) demonstrate this
action so that somebody else could learn how to perform it, (3) pantomime this
action without using the object so that somebody else could learn how to perform it,
and (4) pantomime this action without using the object so that somebody else could
distinguish it from another action. The results confirm that actors exaggerate and
slow down their movements in demonstrations and pantomimes when compared to
ordinary actions.

The 45th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Stimuli that are physically salient—e.g., brighter or differently colored to others in the visual scene—capture eye gaze and attention. Many studies have shown that color-singleton distractors slow visual search for a target, even when color is irrelevant to the task at hand. In the current study we investigated whether participants could use pre-trial information about the color of an upcoming distractor to prevent themselves from getting distracted by it. To ensure that participants were motivated to try and use the pre-trial information, we also provided performance-contingent reward on some trials. Results showed that reward reduced distraction by physically salient stimuli relative to the baseline (distractor-absent condition). However, participants could not capitalize on information provided about the color of the upcoming distractor to further improve visual search performance. This study highlights the fast and reflexive nature of attentional capture by physically salient distractors, which is difficult to control strategically, even when motivated to do so.

Existing studies have suggested that there may be a link between perception and production of speech sounds. In this paper we examine this link using data collected on Singapore English-Mandarin bilingual adults. We used a 2AFC task to measure perception of the Singapore Mandarin [tsʰuə́n]-[ʈʂʰuə́n] alveolar-retroflex contrast, and measured production using centre of gravity (CoG) measurements on speech recordings of alveolar and retroflex words. We found that a perception-production link may exist in our participants, with participants who exhibit less retroflexion in speech showing less sensitivity to retroflexion in ambiguous speech sounds.

We propose a novel approach that utilizes virtual reality (VR) and simulation environments to quantify the impact of visual impairments (VIs) on daily tasks, e.g., to what extent does glaucoma slow people down in wiping a table or chopping vegetables? We utilize clinical data from patients to develop visual field models, allowing VR to mimic the visual perception of VI patients as if it is seen through their eyes. Additionally, we leverage BEHAVIOR, the state-of-the-art simulation environment, to recreate a household environment for six daily activities. By measuring the disparity between the subjects' performance with and without VI, we can accurately quantify the impact of VIs. We further quantify the effects of VIs on body and eye movements, and model how movement strategies affect task performance under the influence of VIs. We hope our results can provide valuable insights into the challenges faced by individuals with VIs.

Quantifying the Effect of Visual Impairments on Daily Activities in Virtual, Interactive Environments

When reading a text, readers not only recognise words and retrieve their meanings as they construct a mental representation of the text, but they also process the physical location of the text, including the position of key information. This study investigates how different presentation formats (prints vs. digital) influence the ability to locate information in texts, and if this is influenced by different types of text, and age. Generalized Linear Mixed Models (GLMM; Baayen, 2008) starting with maximal random effects structure (Barr et al., 2013) are employed for analysis. Preliminary analyses (n=74 out of 120 pre-registered) indicate that participants in the print condition outperformed their peers in the digital condition on the measure of location of information, but no difference was found between different text types. Additionally, results suggest that spatial working memory is positively related to the ability to locate information in texts.

Previous eye-movement research on reading and comprehension typically reports better performance in L1 reading as compared to L2. However, the same may not be true in cases where knowing and reading a second language is necessary for acquiring education. To explore this issue, we asked 10 normal participants to read a text in Hindi (L1) and English (L2) in a naturalistic reading paradigm while their eye-movements were being recorded. The aim of the study was to test efficiency of reading in both the languages and compare them. Results revealed reading advantage for L2 for all eye-movement dependent variables (average and trial level fixation counts, gaze duration and run counts). The results were also correlated with independent variables like frequency (zipf) and word complexity score (length) in both languages.

Research in cognitive development suggests that very early in development children, even infants, may reason about social interactions between individuals that are likely to be relevant for representing leadership (e.g., Stavans & Baillargeon, 2019). In addition, some children develop as leaders (e.g., Kinkead-Clark, 2019; Li et al, 2007), and the specific behaviors they demonstrate are consistent with leadership theories (e.g., Direction, Alignment, and Commitment; Drath et al., 2008). The current study tests whether children represent leadership in terms of Direction, Alignment, and Commitment to shed light on leadership representations in cognitive development. When presented with a ‘sample’ event portraying leadership (or not) followed by another pair of events (only one portraying leadership), 10-13 year olds (N = 24) selected the correct match event significantly above chance; M= 68.50, SE = 4.88, t(23) = 13.91, p < .001. The findings have implications for cognitive theories by clarifying the nature of leadership representations.

Children’s Representations of Events: Categorizing Leadership

Research in cognition and social psychology of organizations have explored perception of leadership. Yet, these investigations remain unconnected. The current study puts forth an approach to studying leadership cognition by 1) using leadership theory to define leadership behavior in an experimental context (in terms of Direction, Alignment, Commitment), and 2) using the Match-to-Sample task to test leadership categorization in adults. When presented with a ‘sample’ event portraying servant leadership followed by another pair of events (only one portraying servant leadership and the other portraying either: task leadership, social interaction, and virtuous interactions), adults (N = 330) selected the correct match event significantly above chance; M=.57 (SE = .01), t(329) = 8.00, p < .001. The findings have implications for cognitive theories by clarifying the nature of leadership representations, as well as for social organizational psychology by introducing a cognitive, non self-report measure of leadership understanding.

Adults’ Event Representations: Categorizing Servant Leadership

How and why do people share opinions online? In research conducted offline, the social identity of the audience is a key factor: whether they are composed of one’s ingroup or outgroup affects what people share and why. Do people behave similarly and for similar reasons online? To test this, we put participants (N = 326) in imaginary forums belonging to their ingroup and outgroup. In each, people selected statements to share, along with reasons for doing so. The results showed a high degree of heterogeneity; people shared nearly all kinds of statements with both audiences, for a variety of reasons. However, there were also consistent patterns. Identity expression was the most common reason for sharing to both audiences, but this led to different things being shared to each. To the ingroup, people preferred to share statements expressing ingroup beliefs, while to the outgroup, they preferred statements expressing universal beliefs.

Interpersonal coordination is a key determinant of successful social interaction but is disrupted for people who experience social anxiety. Effective coordination rests on individuals directing their attention toward others, an effect well-documented in previous literature. Yet, little research has considered the concurrent behaviour of interaction partners. Using a novel virtual reality task, we investigated how partner gaze (i.e., direct vs. averted) influenced the emergence of coordination. The results revealed two novel effects: (i) spontaneous coordination was diminished in the averted (cf. direct) gaze condition; (ii) spontaneous coordination was positively related to symptoms of social anxiety, but only when partner gaze was averted. This latter finding contrasts the extant literature and points to a boundary condition of the social anxiety-coordination association (i.e., social distance). More broadly, this work provides further evidence that emergent patterns of interpersonal coordination fluctuate as a function of changes in social context and the behaviour of others.

Investigating the Influence of Partner Gaze on the Relationship Between Interpersonal Coordination and Social Anxiety

This study investigated the impact of refutative elements in others’ comments on accepting fallacious claims about food nutrition. Four types of comments were used, two of which included refutative elements (challenging evidence and deductive process). A multiple regression analysis was conducted with 506 participants’ agreement with the fallacious claim as the dependent variable and the type of comment and their agreement before exposure to the comments as independent variables. The study also considered individual differences such as media literacy, information literacy, cognitive reflection, and interest in and familiarity with the topic. The results showed that presenting comments that challenged the deductive process significantly decreased agreement when participants had higher agreement before exposure. Further analysis of participants with high initial agreement revealed significant effects of all three comment types. A supplemental survey (n=182) suggested that the perceived negativity and usefulness of the comments influenced the participants' agreement.
