Forced Choice Task

When interacting with other entities, we make inferences about their internal states using our own minds as models (i.e., mentalizing). This process relies on the rapid, automatic perception of a mind. In two experiments, we investigate whether these automatic processes of mind perception are impaired when interacting with agents that are not easily classified as human or robot. We hypothesized that an agent falling on the category boundary between human and non-human (i.e., a humanoid) would be difficult to categorize and that this ambiguity would result in increased cognitive load. In Experiment 1, participants rated agents with varying degrees of humanness in terms of their ability to have internal states. The humanoid agent was perceived as categorically ambiguous, as evidenced by the intermediate ratings of internal states. In Experiment 2, participants categorized each agent as human or non-human in a forced-choice task. The humanoid agent produced less consensus and longer reaction times, indicating that the humanoid’s ambiguous mind status produces a cognitive conflict. These findings suggest that performance is negatively impacted by the presence of agents that cannot be easily classified as human or non-human.

Different Levels

The vulnerability of statistical learning has been demonstrated in reading difficulties in both the visual and acoustic domains. We examined segmentation abilities of adolescents with three different levels of reading fluency in the acoustic verbal and visual nonverbal domains. We applied online target detection tasks, where the extent of learning is reflected in differences between reaction times to predictable versus unpredictable targets. Explicit judgments of well-formedness were also elicited in an offline two-alternative forced choice task. A significant online learning effect was observed in all groups in both domains, and online patterns were similar in participants with low, medium and high reading fluency. On the offline measures, all groups were at chance in the visual, but not the verbal domain. These findings suggest that there is no robust statistical learning impairment associated with reading problems either in the visual or the acoustic domain in adolescents. Results also imply that offline measures may mask learning abilities, and measuring learning online can provide a deeper understanding of the learning process and of its potential deficits.

Negative Effect

Knowing the internal states of others is essential to predicting behavior in social interactions and requires that the general characteristic of ‘having a mind’ is granted to our interaction partners. Mind perception is a highly automatic process and can potentially cause a cognitive conflict when interacting with agents whose mind status is ambiguous, such as artificial agents. We investigate whether mind perception negatively impacts performance on tasks involving artificial agents due to cognitive conflict processing caused by a potentially increased difficulty to categorize them as human versus non-human. Experiment 1 shows that an ambiguous humanoid stimulus negatively impacts performance on a vigilance task that is known to be sensitive to the drainage of cognitive resources. This negative effect on performance vanishes when participants are pre-exposed to the stimulus be-fore the vigilance task (Experiment 2 and 3). The effect of pre-exposure on performance recovery is independent of whether participants explicitly resolve the cognitive conflict by answering mind-related questions (Experiment 2) or implicitly by judging the stimuli on a set of physical features (Experiment 3). Together, the findings suggest that mind perception is so automatic that it cannot be suppressed even if it has negative effects on cognitive performance.

Asymmetric number attraction effects have been typically explained via a privative markedness account: plural nouns are more marked than singular ones and thus stronger attractors. However, this account does not explain results from tripartite systems, in which a third number value is available, like paucal. Here we tested whether attraction effects can be driven by specific markedness sub-components, such as frequency/naturalness of use, using Serbian, in which participles can agree with masculine subjects in singular, plural and paucal. We first conducted a naturalness judgment task, finding the following naturalness/frequency pattern: singular,plural<paucal. In a subsequent forced-choice task, we presented participants with preambles containing a singular, a plural or a paucal headnoun (the castle[Sg] /two castles[Pauc] /the castles[Pl]) modified by singular/plural/paucal attractors (with the window[Sg] /with two windows[Pauc] /with the windows[Pl]). Three options were provided to complete the sentence (resembles[Sg] /resemble[Pauc] /resemble[Pl] gothic architecture).Both accuracy and reaction times (RTs) were collected. Accuracy data reflected the naturalness/frequency pattern, with paucal being the strongest attractor, and plural and singular attracting equally. However, reaction times showed a difference between singular and plural, suggesting co-influence of both frequency/naturalness and morphological markedness. We emphasize the necessity of re-defining markedness and testing attraction through different markedness sub-components (i.e. frequency/naturalness) to explain attraction cross-linguistically.

Purpose Previous studies showed early production precedes late perception in Cantonese tone acquisition, contrary to the general principle that perception precedes production in child language. How tone production and perception are linked in 1st language acquisition remains largely unknown. Our study revisited the acquisition of tone in Cantonese-speaking children, exploring the possible link between production and perception in 1st language acquisition. Method One hundred eleven Cantonese-speaking children aged between 2;0 and 6;0 (years;months) and 10 adolescent reference speakers participated in tone production and perception experiments. Production materials with 30 monosyllabic words were transcribed in filtered and unfiltered conditions by 2 native judges. Perception accuracy was based on a 2-alternative forced-choice task with pictures covering all possible tone pair contrasts. Results Children's accuracy of production and perception of all the 6 Cantonese tones was still not adultlike by age 6;0. Both production and perception accuracies matured with age. A weak positive link was found between the 2 accuracies. Mother's native language contributed to children's production accuracy. Conclusions Our findings show that production and perception abilities are associated in tone acquisition. Further study is needed to explore factors affecting production accuracy in children.

Skipping Breakfast

Abstract. It has been generally accepted that skipping breakfast adversely affects cognition, mainly disturbing the attentional processes. However, the effects of short-term fasting upon brain functioning are still unclear. We aimed to evaluate the effect of skipping breakfast on cognitive processing by studying the electrical brain activity of young healthy individuals while performing several working memory tasks. Accordingly, the behavioral results and event-related brain potentials (ERPs) of 20 healthy university students (10 males) were obtained and compared through analysis of variances (ANOVAs), during the performance of three n-back working memory (WM) tasks in two morning sessions on both normal (after breakfast) and 12-hour fasting conditions. Significantly fewer correct responses were achieved during fasting, mainly affecting the higher WM load task. In addition, there were prolonged reaction times with increased task difficulty, regardless of breakfast intake. ERP showed a significant voltage decrement for N200 and P300 during fasting, while the amplitude of P200 notably increased. The results suggest skipping breakfast disturbs earlier cognitive processing steps, particularly attention allocation, early decoding in working memory, and stimulus evaluation, and this effect increases with task difficulty.

Choice Reaction Times

Abstract Several studies have shown faster choice-reaction times to positive than to negative facial expressions. The present study examined whether this effect is exclusively due to faster cognitive processing of positive stimuli (i.e., processes leading up to, and including, response selection), or whether it also involves faster motor execution of the selected response. In two experiments, response selection (onset of the lateralized readiness potential, LRP) and response execution (LRP onset-response onset) times for positive (happy) and negative (disgusted/angry) faces were examined. Shorter response selection times for positive than for negative faces were found in both experiments but there was no difference in response execution times. Together, these results suggest that the happy-face advantage occurs primarily at premotoric processing stages. Implications that the happy-face advantage may reflect an interaction between emotional and cognitive factors are discussed.

Chronological Sequence

An eye tracker experiment investigated 4-, 6-, and 8-year old children’s cognitive processing of film cuts. Nine short film sequences with or without editing errors were presented to 79 children. Eye movements up to 400 ms after the targeted film cuts were measured and analyzed using a new calculation formula based on Manhattan Metrics. No age effects were found for jump cuts (i.e., small movement discontinuities in a film). However, disturbances resulting from reversed-angle shots (i.e., a switch of the left-right position of actors in successive shots) led to increased reaction times between 6- and 8-year old children, whereas children of all age groups had difficulties coping with narrative discontinuity (i.e., the canonical chronological sequence of film actions is disrupted). Furthermore, 4-year old children showed a greater number of overall eye movements than 6- and 8-year old children. This indicates that some viewing skills are developed between 4 and 6 years of age. The results of the study provide evidence of a crucial time span of knowledge acquisition for television-based media literacy between 4 and 8 years.

Social signals, such as changes in gaze direction, are essential cues to predict others’ mental states and behaviors (i.e., mentalizing). Studies show that humans can mentalize with non-human agents when they perceive a mind in them (i.e., mind perception). Robots that physically and/or behaviorally resemble humans likely trigger mind perception, which enhances the relevance of social cues and improves social-cognitive performance. The current ex-periments examine whether the effect of physical and behavioral influencers of mind perception on social-cognitive processing is modulated by the lifelikeness of a social interaction. Participants interacted with robots of varying degrees of physical (humanlike vs. robot-like) and behavioral (reliable vs. random) human-likeness while the lifelikeness of a social attention task was manipulated across five experiments. The first four experiments manipulated lifelikeness via the physical realism of the robot images (Study 1 and 2), the biological plausibility of the social signals (Study 3), and the plausibility of the social con-text (Study 4). They showed that humanlike behavior affected social attention whereas appearance affected mind perception ratings. However, when the lifelikeness of the interaction was increased by using videos of a human and a robot sending the social cues in a realistic environment (Study 5), social attention mechanisms were affected both by physical appearance and behavioral features, while mind perception ratings were mainly affected by physical appearance. This indicates that in order to understand the effect of physical and behavioral features on social cognition, paradigms should be used that adequately simulate the lifelikeness of social interactions.

How do COVID-19 experts psychologically manage the pandemic and its effects? Using a full year of press briefings (January 2020–January 2021) from the World Health Organization ( N = 126), this paper evaluated the relationship between communication patterns and COVID-19 cases and deaths. The data suggest as COVID-19 cases and deaths increased, health experts tended to think about the virus in a more formal and analytic manner. Experts also communicated with fewer cognitive processing terms, which typically indicate people “working through” a crisis. This report offers a lens into the internal states of COVID-19 experts and their organization as they gradually learned about the virus and its daily impact.
