State authenticity is the subjective sense of being one’s true self in a particular situation (Lenton, Bruder, et al., 2013). Previous studies suggested that the current mood influenced state authenticity because the judgment of state authenticity was made heuristically via available information (i.e., mood). However, the results were not clear. We examined whether the mood manipulation with short movies would affect state authenticity. The results partially supported the hypotheses; participants in a positive mood reported a higher degree of true self and less self-alienation than those in a neutral mood. However, the negative mood had no consistent effect on state authenticity. These results suggest that the effect of mood on state authenticity is limited or more complex than previously thought and point to the necessity for further investigations.

<p>Visual perception, receiving a two-dimensional (2D) visual input, often constructs the three-dimensional (3D) perceptual image. Although there are generally multiple structures in the external world that give an equivalent two-dimensional retinal image, the perceptual process naturally and easily infers only one 3D structure as the solution. However, the following problems are not obvious at all: what kind of structure can be obtained as a 3D perceptual image from certain 2D information, and why do we get a three-dimensional perceptual image instead of a two-dimensional one. In the present study, we investigate this problem by untangling the Necker Cube phenomenon, and propose a novel theory of three-dimensional visual perception from the viewpoint of the efficiency of information coding. Among the possible structures that can yield the 2D retinal image of the Necker Cube, the structure of the typical three-dimensional perceptual image of the Necker Cube maximizes the symmetry (in group theory). This maximization of symmetry is characterized by the pairs of adjoint functors (in category theory). Therefore, according to this proposed theory, "the Necker Cube" in the three-dimensional space is perceived as the most efficient encoding of the two-dimensional retinal image.</p>

The emergence of &ldquo;Sense of agency&rdquo; contributes to self-recognition. However there are few useful experimental paradigms for evaluating the development process of the sense of agency in young infants because the sense of agency is a subjective sense and young infants cannot verbally describe their internal experience. In this article, we propose a new experimental paradigm for examining the sense of agency using on-line eye tracking which we named &ldquo;eye-scratch task&rdquo;. This task enables us to evaluate the emergence processes of the sense of agency by a trajectory of voluntary eye movement. Besides, this task enables direct comparison of eye movement trajectories between infants and adults in common criteria. Hence, we can discriminate whether an infant feels the sense of agency or not by comparison with adults. Further, we analyzed participants' behavior in the task by the concept of feed-forward model that are the most famous computational frameworks for motor control and sense of agency. And we claim that our new infant's model based measurement give fruitful suggestions to the computational modeling for the development process of the sense of agency and self-recognition.

According to a widely held view, the object-subject-verb word order in Japanese is derived from the subject-object-verb word order by shifting the object to the sentence-initial position. This movement of the object, called scrambling, is hypothesized to leave “a trace” in the original object position (Saito, 1985). With regard to this view, during online sentence processing, a fronted object must be associated with its trace (filler-driven parsing). If a human actually processes scrambled sentences by filler-driven parsing, it is assumed that an object is reactivated and the processing load increases at the trace position. Although many psycholinguistic studies have been conducted in order to investigate the processing of a trace at the trace position, few studies have focused on processing around the trace positions. In the present study, by using a cross-modal lexical priming (CMLP) task that is capable of measuring the processing load and the activation level of an object at arbitrary positions, we investigated the processing around the trace positions in Japanese clause-internal scrambled sentences. In this study, in order to correct the problem encountered in the preceding study (Nakano et al., 2002) using the CMLP task, we did not measure the direct priming effect; however, we measured the indirect priming effect as a method of investigating the activation level of an object. When the data of all the participants were analyzed together, the increases in the processing load and the reactivation of an object around the trace position were not revealed. However, because of the difficulty of the CMLP task, the previous study (Nakano et al., 2002) presented the reactivation of an object at the trace position for participants who responded to lexical decisions quickly and possessed a high working memory capacity. Therefore, the participants in this study were divided into fast and slow groups based on their lexical decision latencies during the task. The results that reflect the filler-driven parsing were revealed only for the fast group. In the fast group, the processing load at the trace position was found to exceed the load at the position preceding and following the trace position. Further analyses of the results showed that the activation level of an object increased only at the trace position.

As an unprecedented phenomenon that might characterize new relations between people and domestic artifacts, a craze for a toy doll was analyzed in middle-aged people. The makers of the doll, which is modeled on a virtual character, have sold more than 700 thousand over the last three years in Japan alone, and the age distribution of buyers indicates a modal age of 51-60 year old. In this paper, 51 fan letters and 271 Web postings spontaneously sent to the toy maker were analyzed in terms of communicative functions and affective-cognitive contents. The results indicate that (a) the doll owners believe that the doll facilitates their interaction with family members and with friends, and (b) the doll owners attribute positive feelings in terms of both mental and physical states to the doll. The effects of affective attachment are discussed in terms of human emotion model.

Pointing to an object and saying a word is an ambiguous form of reference, because there are an indefinite number of logically possible hypotheses about the meaning of a word. But children are very proficient at learning words. That led us to postulate constraints on the hypotheses that children consider about the meanings of words. In fact, the previous studies have shown that children aged two or over are highly biased word learners (Landau et al., 1988; Merriman & Schuster, 1991). Much of the debate has centered on whether this idea of constraints implies innate and fixed word learning principles, and whether these principles are by nature domain-specific. This paper reviewed the studies concerned with this debate. The previous studies showed that those learning principles emerged in the course of early word learning (Jones et al., 1992), and that children's use of them became more domain-specific with age (Smith et al, 1994). These findings suggest that the principles and the domain-specific use of them may be the consequence of word learning, not innate. But following two facts are notable. First, young children rapidly find the principles in the course of learning first 50 words, although it is difficult for children of this age to examine possible hypotheses systematically. Second, some findings (Haryu, 1996; Smith et al., 1996) suggest that the use of principles in early word learning is not accesible to deliberate control. These facts lead me to assume that infants are born, not with some concrete beliefs about word meanings, but with some constrained mechanism that guides infant's learning the principles about word meanings.

Many types of humanoid robots have been developed recently, and they are mainly designed for social interaction with human beings. The most communicative partners for human beings are other humans. Therefore, to develop successful communicative robots, it is important to know how closely they resemble a human. In the present study, we attempted to evaluate the human likeness of a humanoid robot (Robovie) by using near-infrared spectroscopy (NIRS). Since activity of the human mirror neuron system (MNS) is thought to reflect the perceived human likeness of observed agents,we compared MNS activity during observations of an action performed by a human and the robot. Seven male and ten female participants were included in the study, and eventually, fourteen of them were analyzed. NIRS probes were placed at the bilateral premotor and primary motor areas, which are components of the MNS. Under observation conditions, stimuli were presented live or on a video monitor; there were four observation conditions, namely, live-human, live-robot, video-human, and video-robot. After the observation conditions, the participants executed the same action performed by the human agent in the observation conditions by themselves (execution condition). We identified the NIRS channels in which significant activation was induced under both the observation and execution conditions, and used this information to determine the possible regions reflecting MNS activity. We found no significant effect of the agent (human/robot) on MNS activity, and this indicated that MNS response in the motorrelated area is relatively analogous irrespective of the agent (human/robot). However,the effect of the mode of presentation (live/video) was found in a few channels. Two channels corresponding to the left ventral premotor cortex were activated more strongly in the live condition than in the video condition, particularly when the agent was the human. In contrast, one channel corresponding to the right primary motor cortex was activated more strongly in the video condition than in the live condition only when the agent was the robot. These findings suggest that live presentation of action is necessary to reveal true brain activity in actual situations.

“Moving pictures on sliding doors” date back to the Edo Era in Japan. These pictures were called moving pictures because they seem to move when they are viewed while moving. The aim of this study was to determine the mechanism underlying this illusionary phenomenon. For that purpose, photographs of a “moving picture” on sliding doors were taken using a digital camera, and the characteristic points on each image were digitized and stored in a computer. Then changes in perception of the picture with movement of the viewpoint of the observer were computed by using a coordination transformation technique. The results of calculation revealed that the picture had been painted from a bird's-eye view and that the illusionary motion is seen when the observer views the picture from an oblique angle while moving along the length of the sliding doors. When viewing the picture from an oblique angle while moving, distances from points on the picture to the observer's viewpoint change, and these changes in distances give rise to the illusionary motion of the picture. Thus, the mechanism by which the picture is perceived as moving is motion parallax.

The purpose of this study was to examine the conception of learning and learning behavior for each goal orientation type from the multiple-goals perspective and to clarify the characteristics of each type. Questionnaires were conducted with fourth-year undergraduate students, and responses for 340 students were analyzed. We created four goal orientation types based on goal orientation combinations: <Low-goals>, <High-goals>, <High-Performance-Avoidance-goal>,and <High-Learning-goal> and examined conception of learning and learning behavior of each type. As a result, it was suggested that conception of learning and learning behavior differ depending on goal orientation type. <High-goals> tended to have multiple conceptions of learning, <High-Learning-goals> tended to have Active conception of learning, and <Low-goals type> and <High-Performance-Avoidance-goals> tended to have Passive conception of learning. It has been shown that the perception and learning behavior of <High-goals type> and <High-Leaning-goal type> are similar, we showed that these two types of the conception of learning are different and clarified the characteristics of each type.

The aim of this paper is to discuss the role of maps in the cognition of geographic space. The research topics were divided into (1) maps as a model of spatial cognition, and (2) maps as a source of spatial knowledge. As for the first topic, maps have become a conceptual model of the spatial cognition and enabled us to elaborate the model of cognitive processing of geospatial information, since Tolman (1948) devised the term of &ldquo;cognitive map&rdquo;. As a result, methods for measuring distortions in cognitive maps has been developed and applied by geographers. On the other hand, the role of maps as a source of spatial knowledge will become important as geographic information technologies spread among people. Specifically, advanced techniques for communicating geographic information through 3D view, animation, sound, and VR enabled by GIS lead to reconsideration of the dichotomy between direct and indirect sources of information. Hence, recent trend of digitization of geospatial information can change the role of maps in the cognition of geographic space.

This study examined the effects of haptic stimuli through visual stimuli in interpersonal behavior. The experiment participants were divided into three groups. The “harsh” group experienced harsh haptic stimuli using a web browser. Similarly,the “sticky” group experienced sticky stimuli. The control group did not experience any visual stimuli. After the experience, the participants were asked to join a public goods game. The experiment results showed that the investment amount of the “sticky” group was significantly higher than that of the other two groups. On the other hand, the investment amount of the “harsh” group was less than that of the other two groups. These results thus indicated that the “sticky” group behaved in a cooperative manner, while the “harsh” group behaved in an uncooperative manner. The experiment results thus suggested that haptic experience through visual stimuli can evoke haptic priming.

Maternal mind-mindedness is known to be a tendency of caregivers to interpret their socially immature infants as social agents and researchers have indicated this is one of promotion factors of infant social development. In this paper, we focused on such caregiver's tendency in mutual imitation of vowels and modeled infant vowel development to investigate the effect of caregivers on infant development. Computational simulation results in our previous study of caregiver-infant mutual imitation showed what we call auto-mirroring bias of the caregiver has a guiding effect in vowel development. This hypothesized bias is the tendency to interpret infant's utterances as more accurate imitations of the caregiver's precedent utterances and considered to be one of behaviors of the mind-mindedness. To verify this bias, we further examined how adult's interpretation was biased by measuring their imitations of synthesized vowels. The result of this subject experiment indicated the bias was enhanced by the anticipation to be imitated. These results of our studies imply the possibility that the way caregiversimitate their infant based on their interpretation of their infants lets them learn caregiver's way of interpreting others, i.e. sociality.

In 2004, Ninio suggested that the process of comprehending noun phrases such as “black shoes” included two steps: comprehending the noun “shoes” and the addition of the attribution “black.” Based on this assumption, Ninio predicted that the developmental process of comprehending noun phrases must progress through a phase in which children understood only the noun. She demonstrated the validity of her assumption through experiments conducted in Hebrew. However, her results were confounded by the word order of the noun phrase in the Hebrew language, in which the noun is the first word and the headword. In this study, we used Japanese phrases to eliminate the artifacts of the above study, because in the Japanese language, the noun is neither the first word in a noun phrase, nor the headword in an adjective phrase. Results indicated that also in Japanese, there is a developmental phase in which children comprehended only the noun in the noun phrases, which confirmed Ninio's assumption. However, there was also a phase in which children comprehended only the noun in the adjective phrases. These results cast doubt on Ninio's suggestion that the process of comprehending the noun phrase includes two steps, or that this two-step process results in a phase in which children comprehend phrases based only on the noun. We think current results relate the idea of noun dominance in children's learning of new words as described by Gentner in 1982, and this dominance influences children's attention by directing it to the noun when comprehending phrases.

Deep Learning achieved significant progresses in building intelligent systems. Some state-of-the-art Deep Learning systems are touted as “human parity” or even “super human”. At the same time, it is often criticized for the lack of understanding of internal workings especially when such systems are considered for real world applications. Cognitive Science, on the other hand, is a scientific discipline aiming to understand internal workings of human-like intelligent behaviours. Thus a question arises: Is Deep Learning a subject of Cognitive Science? This article discusses what can be a subject of Cognitive Science and whether Deep Learning qualifies as such. It is also discussed what kind of connections can be established between these two disciplines even if Deep Learning is not be a direct subject of Cognitive Science.

This study aims to investigate the characteristics of effective interaction between a therapist and his/her child client with autism spectrum disorder during a session of occupational therapy. Four sessions were video-recorded and analyzed, including one conducted by a novice therapist and three by expert therapists. Three children with autism spectrum disorder who were able to take part in everyday conversations also participated in this study. In study 1, we coded the therapists’ utterances according to their function in the context through a session. In study 2, we segmented the video-recording of a session based on the goal of child behavior, recorded the therapists’ physical support, and examined not only the temporal relationship between the therapists’ utterances and physical support but also the children’s proactive behavior. The results indicated that the expert therapists appropriately provided attentive utterances and physical support according to the children’s actions. We discuss a new and useful framework for understanding therapist support and children with developmental disabilities.

Recently, mindreading ability is the topic of intensive investigations, fired by the “Theory of Mind” research by Premack & Woodruff. Few researchers, however, tried to define “mindreading” algorithmically. We mindread other people everyday, and think we know what mindreading really is—e.g. to reproduce in ourselves the “thought” existing in other's mind. Unfortunately, this definition cannot be applied for machine systems. Even for human beings or animals we cannot examine the thought in other's mind directly, and there is no method to verify the coincidence. We propose a definition of “mindreading” independent of the inner representation (thought) of mindreaders and mindreads. Next, Multi-player Prisoner's Dilemma Game (MPD) is proposed as a task where mindreading is expected to be effective for the survival of the players. Computer simulation shows “(by our definition) mindreading programs” are actually acquired through evolution in the MPD society. Lastly the validity of our definition of mindreading, the implication of our definition, and condition for the emergence of mindreading are discussed.
