Changes in Children's Episodic Narratives Through Long-Term Repeated Recall: Longitudinal Case Studies1

This study aimed to investigate whether a child's narrative of a particular past episode would change in repeated reporting over the long term, and if so, how it would change. To answer these questions, I conducted longitudinal case studies of episodic reports by children every 2–6 months, from their early childhood to the age of 10–15 years. Criteria for inclusion were set in advance; seven episodic narratives meeting these criteria were analyzed. Two types of changes in the narratives were observed, as expected: that of including other information, and that of an event suddenly being reported after no recall for several years. Information from the children's surroundings seemed to be substantially involved in these changes in their episodic narratives. The present results also indicate that mothers' episodic memories are not always reliable and that the schema children have can influence their episodic memories.     

Branding ‘Canadian Experience’ in Immigration Policy: Nation Building in a Neoliberal Era

This paper examines the branding of ‘Canadian experience’ in Canadian immigration policy as a rhetorical strategy for neoliberal nation-building. Since 2008, the Canadian government has introduced an unprecedented number of changes to immigration policy. While the bulk of these policies produce more temporary and precarious forms of migration, the Canadian government has mobilized the rhetoric of ‘Canadian experience’ as a means to identify immigrants who carry the promise of economic and social integration. Through a critical discourse analysis of Canadian print media and political discourse, we trace how the brand of Canadian experience taps into the affective value of national identity in an era of global economic insecurity. We also illustrate how the discourse of Canadian experience (CE) remains ideologically deracialized, such that the government’s embrace of CE as an immigrant selection criterion dismisses the discriminatory effects that this discourse is shown to have for racialized immigrants in Canada.     

Bodily perspective taking goes social: the role of personal,interpersonal, and intercultural factors

Mentally placing the self in the physical position of another person might engage social perspective taking because participants have to match their own position with that of another. We investigated the influence of personal (sex), interpersonal (siblings, parental marital status), and cultural (individualistic, collectivistic) factors on individuals' abilities to mentally take the position of front‐facing and back‐facing figures in an online study (369 participants). Replicating findings from laboratory studies responses were slower for front‐facing than back‐facing figures. Having siblings, parents' marital status, and cultural background influenced task performance in theoretically predictable ways. The present perspective‐taking task is a promising experimental paradigm to assess social perspective taking and one that is free from the response biases inherent in self‐report.     

Why theatre-based research works? Psychological theories from behind the curtain

While many scholars have demonstrated the effectiveness of theatre-based knowledge mobilization, fewer studies have examined its psychological dimensions. This article examines some psychological theories that may account for the success behind theatre-based knowledge mobilization. Drawing from the Canadian Experience Project, a study about the labor market challenges of skilled immigrant workers, we show how theatre-based research dissemination efforts attempt to achieve optimal stress by using aesthetic distance processes. We maintain that this psychological capacity to attune to audience members, especially evident in forum theatre, makes theatre a particularly effective means for knowledge mobilization.     

Ideal Body Image Assessment Among Japanese Women

Using the Contour Drawing Rating Scale, we examined the ideal body sizes of young Japanese women who resided in Tokyo. The results indicated that the relationship among the respondents' current, ideal, perceived male-peer, and perceived female-peer ideal body sizes were not necessarily the same across different body mass index levels. For example, the results revealed thatonly the heavier respondents seemed to consider their male-peer ideal body sizes as their own ideal body sizes. The findings also showed that although most participants wished to be slimmer, they believed that their same-sex peers wanted to be even thinner than themselves.     

Shuffle-set dislocation nucleation in semiconductor silicon device

We have found that a shuffle-set dislocation is nucleated in a semiconductor silicon device subjected to severe thermal processing. The dislocation transforms into a dissociated glide-set dislocation after annealing at 500°C. A possible mechanism for the nucleation of a perfect shuffle-set dislocation during thermal processing is that the dislocation nucleus was nucleated at a low temperature during prior ion-implantation processing.     

Developmental changes in consistency of preferential feeling for peers and objects around age four

When do young children come to have an individual mental image of each peer? Forming a stable impression of each person requires maturation of at least two cognitive abilities, inferring the other's mind and episodic memory. According to past studies, the critical period for both these abilities is around age four. Thus, it was hypothesized that the child begins to form a consistent mental image of each peer at or after age four. To test this hypothesis, the temporal consistency of preference for peers was examined in 3-, 4-, and 5-yr.-olds. Each subject was asked "Who do you like better than others in this class?" once a week for three times (Study 1). The results indicated that most of the 3-yr.-olds answered different names as their favorite friends or nonsense things inconsistently week by week, whereas older children tended to answer the same names across weeks. However, changing the question to "Which object do you like best of these alternatives?" dramatically changed the response pattern (Study 2): preferences among nonhuman objects (playthings) were temporally consistent even for 3-yr.-olds. These results indicate that children before age four do have a temporally consistent feeling toward general objects but do not have a consistent firm feeling about personal relationships among peers. The results are discussed in relation to the critical developmental changes about age 4 in other cognitive abilities.     

Sex categorization of conspecific pictures in Japanese monkeys (Macaca fuscata)

We investigated whether monkeys discriminate the sex of individuals from their pictures. Whole-body pictures of adult and nonadult monkeys were used as stimuli. Two male Japanese monkeys were trained for a two-choice sex categorization task in which each of two choice pictures were assigned to male and female, respectively. Following the training, the monkeys were presented with novel monkey pictures, and whether they had acquired the categorization task was tested. The results suggested that while monkeys discriminate between the pictures of adult males and females, discrimination of nonadult pictures was difficult. Partial presentations of the pictures showed that conspicuous and sexually characteristic parts (i.e., underbellies including male scrotums or breasts including female nipples) played an important role in the sex categorization.     

A reduction rule for Peirce formula

A reduction rule is introduced as a transformation of proof figures in implicational classical logic. Proof figures are represented as typed terms in a -calculus with a new constant P ⁽⁽⁾⁾. It is shown that all terms with the same type are equivalent with respect to -reduction augmented by this P-reduction rule. Hence all the proofs of the same implicational formula are equivalent. It is also shown that strong normalization fails for P-reduction. Weak normalization is shown for P-reduction with another reduction rule which simplifies of (( ) ) into an atomic type.This work was partially supported by a Grant-in-Aid for General Scientific Research No. 05680276 of the Ministry of Education, Science and Culture, Japan and by Japan Society for the Promotion of Science.

Visually guided facial actions in rhesus monkeys

We trained 2 monkeys to display facial actions in response to corresponding arbitrary visual cues. Each monkey executed the task successfully, and each displayed two different facial actions corresponding to either hand-sign or color cues. More than 90% of the responses were correct for each monkey. These results provide evidence that monkeys can execute facial actions in response to conditioned visual cues in the absence of social context. These data suggest that facial actions of monkeys are flexible enough for use in further laboratory investigations—for example, in studies on the neural mechanisms underlying the execution of actions.
