When taught a label for an object, and later asked whether that object or a novel object is the referent of a novel label, preschoolers favor the novel object. This article examines whether this so-called disambiguation effect may be undermined by an expectation to communicate about a discovery. This expectation may explain why 4-year-olds do not show the disambiguation effect if a sense modality shift occurs between training and test. In Study 1, 3- and 4-year-olds learned a label for a visible object, then examined two hidden objects manually and predicted which one they would be asked about. Only the older group predicted that they would be asked about the object that matched the visible object. Study 1 also included a test of the standard disambiguation effect, where both the training and test objects were visible. Both 3- and 4-year-olds showed a weaker disambiguation effect in this test when the matching object was unexpected rather than expected. In Study 2, both age groups predicted they would be asked about this object when it was unexpected. In Study 3, both age groups showed a stronger disambiguation effect when allowed to communicate about this object before deciding which object was the referent of a novel label. Metacognitive ability predicted the strength of this disambiguation effect even after controlling for age and inhibitory control. The article discusses various explanations for why only 4-year-olds abided by the pragmatics of discovery in the test of the cross-modal disambiguation effect, but both 3- and 4-year-olds abided by it in the test of the standard disambiguation effect.

AbstractSpeech disfluencies can guide the ways in which listeners interpret spoken language. Here, we examined whether three-year-olds, five-year-olds, and adults use filled pauses to anticipate that a speaker is likely to refer to a novel object. Across three experiments, participants were presented with pairs of novel and familiar objects and heard a speaker refer to one of the objects using a fluent (“Look at the ball/lep!”) or disfluent (“Look at thee uh ball/lep!”) expression. The salience of the speaker's unfamiliarity with the novel referents, and the way in which the speaker referred to the novel referents (i.e., a noun vs. a description) varied across experiments. Three- and five-year-olds successfully identified familiar and novel targets, but only adults’ looking patterns reflected increased looks to novel objects in the presence of a disfluency. Together, these findings demonstrate that adults, but not young children, use filled pauses to anticipate reference to novel objects.

Object Features

This paper studies the task of image captioning with novel objects, which only exist in testing images. Intrinsically, this task can reflect the generalization ability of models in understanding and captioning the semantic meanings of visual concepts and objects unseen in training set, sharing the similarity to one/zero-shot learning. The critical difficulty thus comes from that no paired images and sentences of the novel objects can be used to help train the captioning model. Inspired by recent work (Chen et al. 2019b) that boosts one-shot learning by learning to generate various image deformations, we propose learning meta-networks for deforming features for novel object captioning. To this end, we introduce the feature deformation meta-networks (FDM-net), which is trained on source data, and learn to adapt to the novel object features detected by the auxiliary detection model. FDM-net includes two sub-nets: feature deformation, and scene graph sentence reconstruction, which produce the augmented image features and corresponding sentences, respectively. Thus, rather than directly deforming images, FDM-net can efficiently and dynamically enlarge the paired images and texts by learning to deform image features. Extensive experiments are conducted on the widely used novel object captioning dataset, and the results show the effectiveness of our FDM-net. Ablation study and qualitative visualization further give insights of our model.

AbstractA breeding pair of S. fuscicollis and their young (total N=6 in the first experiment and 8 in the other three experiments) were housed in a relatively large and heavily vegetated greenhouse and tested on their reactions to novel, innocuous inanimate objects. Some supplementary data were obtained on another such group of four individuals. The animals seemed to know the nature and relative positions of objects in their home environment ; i.e. to be capable of "cognitive mapping". Thus, for example, they detected a single novel object among up to 30 simultaneously presented test objects; they discriminated changes in an object's location and orientation; they responded more to changes in two or more parameters than to changes in only one parameter; and they showed apparent object constancy. These discriminations could be made at almost any randomly-designated location in the greenhouse, and with inter-trial intervals of 23 hours or more. Many aspects of the animals' behavior, including the order in which the various individuals approached a given object, the amount of time they remained at the object, and the likelihood (and order) of their responding to it again on subsequent trials, were highly predictable from their ages. There was, however, no "true" single linear correlation value between age and responsiveness. With appropriate sampling of one's subjects, objects and stages of group habituation, one could in fact find any correlation one chooses, from + 1.00 to -1.00; and age-response functions (and changes therein) were orderly functions of other variables.

The Third Party

ABSTRACTChildren as young as two years of age are able to learn novel object labels through overhearing, even when distracted by an attractive toy (Akhtar, 2005). The present studies varied the information provided about novel objects and examined which elements (i.e. novel versus neutral information and labels versus facts) toddlers chose to monitor, and what type of information they were more likely to learn. In Study 1, participants learned only the novel label and the novel fact containing a novel label. In Study 2, only girls learned the novel label. Neither girls nor boys learned the novel fact. In both studies, analyses of children's gaze patterns suggest that children who learned the new information strategically oriented to the third-party conversation.

Dogs and cats use human emotional information directed to an unfamiliar situation to guide their behavior, known as social referencing. It is not clear whether other domestic species show similar socio-cognitive abilities in interacting with humans. We investigated whether horses (n = 46) use human emotional information to adjust their behavior to a novel object and whether the behavior of horses differed depending on breed type. Horses were randomly assigned to one of two groups: an experimenter positioned in the middle of a test arena directed gaze and voice towards the novel object with either (a) a positive or (b) a negative emotional expression. The duration of subjects’ position to the experimenter and the object in the arena, frequency of gazing behavior, and physical interactions (with either object or experimenter) were analyzed. Horses in the positive condition spent more time between the experimenter and object compared to horses in the negative condition, indicating less avoidance behavior towards the object. Horses in the negative condition gazed more often towards the object than horses in the positive condition, indicating increased vigilance behavior. Breed types differed in their behavior: thoroughbreds showed less human-directed behavior than warmbloods and ponies. Our results provide evidence that horses use emotional cues from humans to guide their behavior towards novel objects.

Novel Objects

ABSTRACTStudies report that infants as young as 1 ; 3 to 1 ; 5 will seek out a novel object in response to hearing a novel label (e.g. Halberda, 2003; Markman, Wasow & Hansen, 2003). This behaviour is commonly known as the ‘mutual exclusivity’ response (Markman, 1989; 1990). However, evidence for mutual exclusivity does not imply that the infant has associated a novel label with a novel object. We used an intermodal preferential looking task to investigate whether infants aged 1 ; 4 could use mutual exclusivity to guide their association of novel labels with novel objects. The results show that infants can successfully map a novel label onto a novel object, provided that the novel label has no familiar phonological neighbours. Therefore, as early as 1 ; 4, infants can use mutual exclusivity to form novel word–object associations, although this process is constrained by the phonological novelty of a label.

AbstractExploratory behavior, defined as response to novel objects, was measured in representatives of three lower primate species -greater galago, slow loris, and owl monkey. Test apparatus was a two-compartment cage; animals could choose between remaining on the familiar, home cage side or entering the novel side which contained six manipulable objects. Galagos spent the most time in contact with objects and the least time in retreat to the home cage. Owl monkeys and lorises were less responsive to the test objects but, while lorises actively explored spatial features of the new environment, owl monkeys remained inactive. For all species: i) the greatest degree of responsiveness to novel objects occurred during the first 5 min. of the 15-min. session. 2) initial object contacts were made with the nose; these were brief and were followed by lengthier contacts with mouth and hands. 3) occurrence of the various behavioral categories (object contacts, active responses, inactive responses, and retreat) followed a consistent pattern.

Individual Consistency

ABSTRACTThe study of consistent individual differences in behaviour has become an important focus in research on animal behaviour. Behavioural phenotypes are typically measured through standardized testing paradigms and one frequently used paradigm is the novel object test. In novel object tests, animals are exposed to new (unknown) objects and their reaction is quantified. When repeating trials to assess the temporal consistency of individual differences, researchers face the dilemma of whether to use the same or different ‘novel’ objects, since the same stimulus can result in habituation, while exposure to different objects can result in context-dependent responses. We performed a quantitative assessment of 254 effect sizes from 113 studies on novel-object trials to evaluate the properties of this testing paradigm, in particular the effect of object novelty and time interval between novel-object trials on estimates of individual consistency. We found an increase of sample sizes and an increase of estimates of repeatabilities with time. The vast majority of short-term studies (<one month) used different novel objects, while long-term studies (>one month) used either the same or different novel objects about equally often. The average estimate for individual consistency was r = 0.47 (short-term r = 0.52, long-term r = 0.44). Novelty, time interval between trials and their interaction together explained only 3% of the total heterogeneity. Overall, novelobject trials reliably estimate individual differences in behaviour, but results were very heterogeneous even within the same study species, suggesting susceptibility to unknown details in testing conditions. Most studies that measure novel-object responses in association with food label the trait as neophobia, while novel-object trials in a neutral context are labelled variously as boldness/shyness, exploratory behaviour or neophobia/neophilia. Neophobia/neophilia is also the term most specific to novel object presentations. To avoid ambiguity, we suggest object neophobia/neophilia as the most specific label for novel-object responses.

Abstract The aim of this study was to test the hypothesis that Thoroughbred (TB) ancestors blood percentage in a pedigree is a potential factor differentiating the level of fearfulness (based on behavior and heart rate (HR)) and performance scores in warmblood stallions. A total of 267 three-year-old warmblood stallions were subjected to the novel-object based test during their participation in the performance tests’ program. The effect of ancestors percentage contribution in the pedigree was analyzed by taking into account horses of four TB (<25.01, 25.01-50.00, 50.01-75.00, >75.00%) ancestor groups. It was found that the stallions with a higher proportion (>75.00%) of TB blood revealed higher values of HR measured at the riding hall just before the start of the fearfulness test. The results showed that the higher proportions of TB ancestors blood in the stallions’ pedigree were correlated with the higher values for total time to pass novel objects when led by a handler during the fearfulness test. Negative correlations were found between the TB percentage and the scores for character and trot evaluated by the trainer as well as rideability evaluated by the test rider. The fi ndings imply that a high proportion of Thoroughbreds in the pedigree may negatively infl uence some performance traits and increase fear reactivity in warmblood stallions.

Pragmatic Reasoning

Abstract As speech is often ambiguous, pragmatic reasoning—the process of integrating multiple sources of information including semantics, ostensive cues and contextual information (Bohn & Frank, 2019)—is essential to understanding a speaker’s intentions. Despite current literature suggesting that certain social cognitive processes such as gaze-processing (Slessor et al., 2014) appear to be impaired in late adulthood, it is not well understood if pragmatic reasoning decline with age. Here, we examined young adults’ (aged 19-25; n=41) and older adults’ (aged 60-79; n=41) ability to engage in pragmatic reasoning in a cue integration task. In Experiment 1, participants had to integrate contextual (participants and speaker knew there were two novel objects but the latter could only see one), semantic (“There’s the [novel-label]” or “Where’s the [novel-label]”), and gaze (speaker looked at the mutually-visible object) cues to identify the referent (Nurmsoo & Bloom, 2008). In Experiment 2, participants received contextual and semantic cues less gaze cue. In both experiments, the target referent object for “There” and “Where” trials was the mutually-visible object and the object the speaker could not see respectively. Overall, young adults outperformed older adults, even in the simpler two-cue Experiment 2 (ps&lt;.006). While older adults were significantly above chance in “There” trials for both experiments as well as “Where” trials in Experiment 2 (ps&lt;.05), they had specific difficulty in integrating three cues in “Where” trials, where a more sophisticated interpretation of the multiple cues was required (p=.42). Our findings provide important insights into an age-related decline of pragmatic reasoning in older adults.
