Different Characteristics

The personality trait of curiosity has been shown to increase welfare in humans. If this positive welfare effect is also true for non-humans, animals with high levels of curiosity may be able to cope better with stressful situations than their conspecifics. Before discoveries can be made regarding the effect of curiosity on an animal’s ability to cope in their environment, a way of measuring curiosity across species in different environments must be created to standardise testing. To determine the suitability of novel objects in testing curiosity, species from different evolutionary backgrounds with sufficient sample sizes were chosen. Barbary sheep (Ammotragus lervia) n = 12, little penguins (Eudyptula minor) n = 10, ringtail lemurs (Lemur catta) n = 8,red tailed black cockatoos (Calyptorhynchus banksia) n = 7, Indian star tortoises (Geochelone elegans) n = 5 and red kangaroos (Macropus rufus) n = 5 were presented with a stationary object, a moving object and a mirror. Having objects with different characteristics increased the likelihood individuals would find at least one motivating. Conspecifics were all assessed simultaneously for time to first orientate towards object (s), latency to make contact (s), frequency of interactions, and total duration of interaction (s). Differences in curiosity were recorded in four of the six species; the Barbary sheep and red tailed black cockatoos did not interact with the novel objects suggesting either a low level of curiosity or that the objects were not motivating for these animals. Variation in curiosity was seen between and within species in terms of which objects they interacted with and how long they spent with the objects. This was determined by the speed in which they interacted, and the duration of interest. By using the measure of curiosity towards novel objects with varying characteristics across a range of zoo species, we can see evidence of evolutionary, husbandry and individual influences on their response. Further work to obtain data on multiple captive populations of a single species using a standardised method could uncover factors that nurture the development of curiosity. In doing so, it would be possible to isolate and modify sub-optimal husbandry practices to improve welfare in the zoo environment.

Novel Objects

Novelty-seeking and harm-avoidance personality traits influence Go/No-go (GNG) learning in humans. Animal studies have also indicated a link between response to novelty and spatial discrimination learning. In the present study, we test the hypothesis that learning rate in a GNG task correlates with the behavioral response of Göttingen minipigs to novelty. In a group of 12 minipigs of mixed genders, response to novelty was measured by numbers of contacts with a novel object, and the total duration of exploration of the novel object. These parameters were correlated to individual learning rate in a GNG task. The number of sessions to reach criterion in the GNG task correlated significantly with the number of contacts to a novel object (r = 0.70, p = 0.03), but not with the duration of object exploration (r = 0.29, p = 0.41). Thus, pigs with a low behavioral response to novelty learned the GNG task faster than did pigs with a strong behavioral response to novelty, indicated by the tendency to approach novel objects. We hypothesize that the critical factor in this relation is difference in emotional reactivity rather than difference in motivation for exploration. In conclusion, in addition to ‘cognitive’ ability, ‘temperamental’ factors are likely to influence learning in individual pigs.

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.

Triggering Events

When object A moves adjacent to a stationary object, B, and in that instant A stops moving and B starts moving, people irresistibly see this as an event in which A causes B to move. Real-world causal collisions are subject to Newtonian constraints on the relative speed of B following the collision, but here we show that perceptual constraints on the relative speed of B (which align imprecisely with Newtonian principles) define two categories of causal events in perception. Using performance-based tasks, we show that triggering events, in which B moves noticeably faster than A, are treated as being categorically different from launching events, in which B does not move noticeably faster than A, and that these categories are unique to causal events (Experiments 1 and 2). Furthermore, we show that 7- to 9-month-old infants are sensitive to this distinction, which suggests that this boundary may be an early-developing component of causal perception (Experiment 3).

Launch Event

In addition to perceiving the colors, shapes, and motions of objects, observers can perceive higher-level properties of visual events. One such property is causation, as when an observer sees one object cause another object to move by colliding with it. We report a striking new type of contextual effect on the perception of such collision events. Consider an object (A) that moves toward a stationary object (B) until they are adjacent, at which point A stops and B starts moving along the same path. Such “launches” are perceived in terms beyond these kinematics: As noted in Michotte's classic studies, observers perceive A as being the cause of B's motion. When A and B fully overlap before B's motion, however, observers often see this test event as a completely noncausal “pass”: One object remains stationary while another passes over it. When a distinct launch event occurs nearby, however, the test event is “captured”: It too is now irresistibly seen as causal. For this causal capture to occur, the context event need be present for only 50 ms surrounding the “impact,” but capture is destroyed by only 200 ms of temporal asynchrony between the two events. We report a study of such cases, and others, that help define the rules that the visual system uses to construct percepts of seemingly high-level properties like causation.

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.

Familiar Stimuli

The aim of the present experiments was to find out how imprinted chicks respond to familiar figures in unfamiliar settings. Experiment I showed that chicks individually imprinted with a coloured stationary disc did not readily approach it when later confronted with it in a larger pen—a confirmation of an earlier finding. Experiment II showed a similar disruptive effect when the chicks were individually presented with a stationary object (a ball) in a pen differing in colour from the original one. Experiment III, however, in which chicks were imprinted to a moving ball, showed unattenuated imprinting when testing took place in a strange environment. It was concluded that the disruptive effect of neophobia can be overcome when a high degree of figure salience ensures powerful imprinting.

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.

Problem Setting

We present a novel problem setting in zero-shot learning, zero-shot object recognition and detection in the context. Contrary to the traditional zero-shot learning methods, which simply infers unseen categories by transferring knowledge from the objects belonging to semantically similar seen categories, we aim to understand the identity of the novel objects in an image surrounded by the known objects using the inter-object relation prior. Specifically, we leverage the visual context and the geometric relationships between all pairs of objects in a single image, and capture the information useful to infer unseen categories. We integrate our context-aware zero-shot learning framework into the traditional zero-shot learning techniques seamlessly using a Conditional Random Field (CRF). The proposed algorithm is evaluated on both zero-shot region classification and zero-shot detection tasks. The results on Visual Genome (VG) dataset show that our model significantly boosts performance with the additional visual context compared to traditional methods.

Pada BP, konstituen  Nod dan Np yang berupa pronominal berada di depan  verba, sedangkan dalam BI konstituen Nod dan Noi selalu di belakang verba. Pada tataran frase nominal, perbedaan terletak pada urutan modifikator demonstratif, dan pronomina persona. Pada BP sebelum nomina inti, sedangkan pada BI setelah nomina inti. Modifikator ekasilaba dan dwisilaba dalam BP terletak di depan nomina inti, sedangkan adjektiva yang lebih dari dua silaba, dan adjektiva yang berkaitan dengan warna, agama, dan verba partisif terletak di belakang nomina inti. Sementara itu, adjektiva dalam BI terletak setelah nomina inti.Kata Kunci: urutan dan bentuk konstituen, klausa, frase nomina, sintaks WORDS ORDERS IN FRENCH AND BAHASA INDONESIA CLAUSESABSTRACTThis research aims at analyzing the similarities and differences of the words orders and their forms in the transitive clauses and its argument, noun phrases, between French and Bahasa Indonesia. The research data resources are taken from written texts i.e.: The novel Le dernier jour d’un comdamné à mort by Victor Hugo and its translation Hari Terakhir Seorang Terpidana Mati by Lady Lesmana. This research uses “segmenting immediate constituent technique” to analyse the data. The result shows that French and Bahasa Indonesia have the same basic words orders in transitive clauses, i.e. verbs precede the object. The differences are found in the characteristic of the object. A prepositional object in French is categorized as the main argument, while in Bahasa Indonesia it is a peripheral argument. The position of Nod and Np constituent, which are pronominal, in French precedes the verb, whereas, in Bahasa Indonesia, they are always placed after the verb. Regarding the noun phrase, the differences are found at the position of demonstrative and possessive modifiers. Their position in French is placed before the main noun, while in Bahasa Indonesia after the main noun. The adjectives with one or two syllables are placed before the main noun and the adjectives with more than two syllables or the adjective related to color, religion, and participles are placed after the main noun. On the other hand, adjective in Bahasa Indonesia is always placed after the main noun.Keywords: words orders and form, clause, noun phrase, syntax

Sedangkan motivasi tokoh untuk merefleksi diri merupakan dorongan/keinginan tokoh untuk mendapatkan sesuatu, dalam hal ini adalah kehidupan yang lebih baik di masa mendatang. Tokoh yang merefleksi diri menunjukkan karakteristik yang berbeda-bedamulai dari perubahan penampilan sampai pada psikologis tokoh.   This study aims to describe the self-reflection of the character in the novel Pesentren Impian by Asma Nadia which is associated with self-motivation and the fulfillment of the needs of Abraham Maslow. The method used is descriptive qualitative. Data collected in the form of a text in the novel Pesantren Impian by Asma Nadia. Data collection is done by reading data sources. Then classifying the data, the data are separated based on problems and research objectives. The data that has been interpreted is then explained in the form of language exposure as a result of an analysis. The results of this research are exposure to the fulfillment of the hierarchy of character needs, character motivation, and character characteristics after self-reflection. The hierarchy of needs fulfilled in the novel Pesantren Impian by Asma Nadia includes physiological needs, security needs, sense of belonging and belonging, self-esteem needs and self-actualization. While the motivation of the character to reflect on himself is the drive / desire of the character to get something, in this case is a better life in the future. People who reflect themselves show different characteristics ranging from changes in appearance to psychological character.
