Experimental design and computational modelling across the cognitive sciences often rely on measures of semantic similarity between words/concepts. Traditional measures of semantic similarity typically rely on corpus-derived linguistic distributional similarity (e.g. LSA) or distance in taxonomic databases (e.g. WordNet), which are theoretically problematic in their lack of grounding in sensorimotor experience. We present a new measure of sensorimotor similarity between concepts, based on multidimensional comparisons of their experiential strength across 11 perceptual and action-effector dimensions in the Lancaster Sensorimotor norms. We demonstrate that, in modelling human similarity and relatedness judgements, sensorimotor similarity has comparable explanatory power to LSA and WordNet distance, explains variance in human judgements which is missed by other measures, and does so with the advantages of remaining both fully grounded and computationally efficient. We further introduce a web-based tool for easily calculating and visualising sensorimotor similarity between words, featuring coverage of nearly 800 million word pairs.

#### About

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.

#### Our History 

* **Society Creation**<br>
The Society was incorporated as a 501(c)(3) non-profit professional organization in Massachusetts in 1979. The organizing committee included Roger Schank, Allan Collins, Donald Norman, and a number of other scholars from psychology, linguistics, computer science, and philosophy. 
<br><br>
* **Conference Creation**<br>
The first conference on cognitive science was held at La Jolla, California in August, 1979, and has occurred annually since then. The proceedings of each conference are published, and those from most years are available through Lawrence Erlbaum Associates, Inc. The annual proceedings of the Cognitive Science Conference represent a major source of information on new work and new ideas in the scientific study of thinking. In 1990, the Society, with help from an anonymous donor, established the David Marr Prize for the best student paper at each annual meeting.
<br><br>
* **Journal Creation**<br>
The Journal, Cognitive Science, began publication in 1976, and is now published by Wiley-Blackwell. The Executive Editor is currently Richard P. Cooper of Birkbeck, University of London, and there are 18 Associate Editors and a 30-member editorial board. It serves as the premier outlet for research reports that intersect two or more disciplines. Copyrights for articles published in the journal are held by the Society. The Governing Board of the Cognitive Science Society voted in late 2006 to found a new journal, Topics in Cognitive Science (topiCS). The Editor in Chief is Wayne Gray, Cognitive Science Department, Rensselaer Polytechnic Institute. The journal seeks to fill a niche not occupied by Cognitive Science Journal or other cognitive science journals. Membership in the Society includes a subscription to Cognitive Science and TopiCS. Copyrights for articles published in the journal are held by the Society.

Are Goffin’s cockatoos capable of transferring a tool-use skill acquired in a certain situation to a new contextual setting on which they have no previous experience? In our study, performance of thirteen adult subjects (divided into two groups: experimental or control) was compared in a two-stage experiment where the learning component about the tool was manipulated by providing a more diverse training for the experimental group in stage one. We hypothesized that this broader learning of the tool's affordances would enable to transfer its use to solve a novel task. Our results show that the experimental group outperformed the control group in stage two (higher success rate and faster learning speed), which we interpret as a product of behavioural flexibility being enhanced during stage one: by operating the tool in more diverse contexts, these individuals might have acquired an advantageous experience, transferrable to tackle an untrained problem more efficiently.

Prosociality is considered one of the driving forces for cooperation in human and animal societies. The presence of prosociality in different taxa suggests convergent evolution. To broaden the phylogenetic spectrum in our understanding of prosociality, we examined two parrot species (i.e., African grey parrots (AGP) and blue-headed macaws (BHM)) using a food-sharing paradigm. By controlling the parrots’ hunger level, we tested how satiation may affect their willingness to share food with their most affiliated partner and a less affiliated partner. We also assessed whether they reciprocated if roles were reversed and examined birds’ regurgitation behaviour following the test condition. Preliminary results show that the parrots did not directly transfer any food pieces to their partner. However, food-sharing by regurgitation subsequent to the test situation occurred between the most affiliative partners and more frequently in the AGP than the BHM. This study highlights parrots as a fruitful model for studying prosociality.

Decades of empirical and theoretical research on human decision-making has broadly categorized it into two, separate realms: decision-making under risk and decision-making under uncertainty, with the Allais paradox and the Ellsberg paradox being a prominent example of each, respectively. In this work, we present the first unified, resource-rational account of these two paradoxes. Specifically, we show that Nobandegani et al.’s (2018) sample-based expected utility model provides a unified, process-level account of the two variants of the Allais paradox (the common-consequence effect and the common-ratio effect) and the Ellsberg paradox. Our work suggests that the broad framework of resource-rationality could permit a unified treatment of decision-making under risk and decision-making under uncertainty, thus approaching a unified account of human decision-making.

A Unified, Resource-Rational Account of the Allais and Ellsberg Paradoxes

Recent work has demonstrated robust learning traps during learning from experience – decision-making biases that persist due to the choice-contingent nature of outcome feedback. In two experiments, we investigate the effect of outcome valence on learning trap development. Participants chose to approach or avoid category exemplars associated with rewards or losses, and, to maximize reward, must learn a categorization rule based on two stimulus dimensions. We replicate previous findings showing that when outcome feedback was contingent upon approaching exemplars, people frequently fell into the trap of using an incomplete categorization rule based on only a single dimension, which was suboptimal for long-term reward. Notably, learning trap development was attenuated in an environment with frequent loss outcomes, even when participants received explicit information about the base rates of gains and losses. The implications of these findings for theoretical models and future research are discussed.

Can losses help attenuate learning traps?

Tone combinations with small integer frequency ratios are perceived as pleasant and are referred to as “consonant”. Human consonance preference has been connected to preference for sounds, such as the human voice, that inherently contain consonant intervals via the harmonic series. As such, we might expect other species with harmonic vocalizations to also show attraction to consonance. We tested budgerigars and humans in a place preference test. Subjects could freely spend time with consonant or dissonant versions of a piano melody. Time spent with stimulus types was used as a measure of attraction. Human females spent more time with consonant stimuli but males showed no preference. In budgerigars neither sex showed a preference. This did not change when repeating the experiment with consonant and dissonant versions of budgerigar sounds. The amount of nonlinearity in budgerigar vocalizations can explain these results engendering relevant implications for future cross-species consonance studies.

No evidence for attraction to consonance in budgerigars (Melopsittacus undulatus) from a place preference paradigm

Neural representations for faces, bodies, and objects have been studied extensively in humans. However, much less is known on how our socio-cognitive niche shaped the evolution of these neural bases. Canine neuroscience allows us to close this gap by studying a longstanding, close companion of humans. Here, we study the neural underpinnings of face, body and object processing in pet dogs (Canis familiaris) and humans. Fifteen awake and unrestrained dogs and forty humans underwent MRI scanning and viewed faces, bodies, objects, and scrambled images. Preliminary results for the dogs indicate temporal regions selective for animate stimuli and a potentially distinct sub-region selective for bodies, and replicate previous findings of category-selective regions in humans. Investigating the multivariate patterns of activation indicates similar categorical object representations in both species. Our findings will provide insights into the potentially convergent evolution of a core cognitive skill in the dog and human brain.

Enhanced behavioural flexibility has been linked to relatively large brain size and social complexity. Aras exhibit both properties. We tested parrots of A. ambiguus and A. glaucogularis in a serial reversal learning paradigm, in which all the individuals completed an acquisition, and 10 reversal learning phases. Behavioural flexibility (and thus learning performance) was measured as the number of errors per trial. We also conducted social observations on individuals’ social interactions. We found that both species made significantly fewer errors per trial during each reversal phase and over the course of ten reversal phases. All individuals gradually developed a generalised learning strategy i.e., ‘win-stay-loose-shift’, and thus showing ‘learning to learn efficiently’. Our results also support the Social Intelligence Hypothesis whereby individuals’ learning performance was positively related to social interaction. These results show that the two Ara species demonstrate behavioural flexibility, and social complexity provides one explanation for varied individual learning performance.

Research suggests that the perception of attractiveness is multimodal, however, it is unclear how visual and auditory cues interact. Voice pitch seems important, as men judge high-pitched female voices to be more attractive, possibly due to their association with youthfulness, fertility, and femininity. We investigated whether an increase in voice pitch in female voices would lead to increased ratings of attractiveness, femininity, and health, and decreased age ratings. In a within-subject design we found higher-pitched female voices were rated more attractive, more feminine, and younger, but not healthier compared to non-manipulated voices. However, when manipulated and control voices were presented simultaneously with synchronized face videos, voice manipulations did not affect the ratings of the faces. These results support the multiple-message hypothesis that voices and faces signal different aspects of an individual’s overall quality. Further experiments will have to examine the effect of face attractiveness manipulations on voice ratings.

Labels may play a role in the formation and acquisition of object categories. We investigated this using a free-categorization task, manipulating the presence or absence of labels and whether labels were random or reinforced one of two alternative categorization cues (taxonomic or thematic relationships). When labels were absent, participants used thematic and taxonomic cues equally to categorize stimuli. When present, labels were used as the primary cue for category formation, with random labels leading participants to attend less to taxonomic and thematic relations between stimuli. When labels redundantly reinforced either thematic or taxonomic cues, the use of the cue in question was boosted along with the use of labels as a cue for categorization. Most interestingly, in spite of previously observed associations between labels and taxonomic grouping, labels did not preferentially boost the use of either taxonomic or thematic cues in comparison with the other.

Labels, Even Arbitrary Ones, Facilitate Categorization

According to a long-standing dogma, Westerners are more capable of thinking abstractly than East Asians. Here, we challenge this generalization by comparing US and Chinese adults in a paradigm case of abstract thinking: analogy. Chinese and American participants completed the most difficult set of Raven’s (2003) Standard Progressive Matrices (SPM), a widely used test of analogical reasoning. For each item, participants attempted to discern the analogical relationships between parts of an incomplete matrix to identify the correct way to complete it. Chinese participants produced significantly more correct answers on the SPM, indicating more successful analogical reasoning. We replicated this result with a second sample of Chinese participants. This cross-cultural difference remained significant when demographic factors were controlled. We predicted this difference, reasoning that East Asian’s sensitivity to context gives them an advantage over Westerners in various kinds of abstract thinking.
