Bootstrapping word order in prelexical infants: a Japanese-Italian cross-linguistic study

Learning word order is one of the earliest feats infants accomplish during language acquisition [Brown, R. (1973). A first language: The early stages, Cambridge, MA: Harvard University Press.]. Two theories have been proposed to account for this fact. Constructivist/lexicalist theories [Tomasello, M. (2000). Do young children have adult syntactic competence? Cognition, 74(3), 209-253.] argue that word order is learned separately for each lexical item or construction. Generativist theories [Chomsky, N. (1995). The Minimalist Program. Cambridge, MA: MIT Press.], on the other hand, claim that word order is an abstract and general property, determined from the input independently of individual words. Here, we show that eight-month-old Japanese and Italian infants have opposite order preferences in an artificial grammar experiment, mirroring the opposite word orders of their respective native languages. This suggests that infants possess some representation of word order prelexically, arguing for the generativist view. We propose a frequency-based bootstrapping mechanism to account for our results, arguing that infants might build this representation by tracking the order of functors and content words, identified through their different frequency distributions. We investigate frequency and word order patterns in infant-directed Japanese and Italian corpora to support this claim.     

Newborn right-holding is related to depressive symptoms in bottle-feeding mothers but not in breastfeeding mothers

This study examines the relationships between infant holding preferences and maternal depression according to the newborn feeding mode. Links between depression and infant holding biases have been observed in mothers [Vauclair, J., Scola, C. (in press). Dépression, alexithymie et latéralisation dans la fa?on de porter un nouveau-né [Infant holding biases in relation to depression, alexithymia and laterality]. Annales Médico-psychologiques; Weatherill, R. P., Almerigi, J. B., Levendosky, A. A., Bogat, G. A., von Eye, A., & Harris, L. J. (2004). Is maternal depression related to side of infant holding? International Journal of Behavioral Development, 28, 421-427] but the fact that breastfeeding has never been studied in relation to these two factors is surprising as breastfeeding has some influence on depression (e.g., [Mezzacappa, E. S., Guethlein, W., Vaz, N., & Bagiella, E. (2000). A preliminary study of breast-feeding and maternal symptomatology. Annals of Behavioral Medicine, 22, 71-79]) and must also affect holding biases. Mothers who just gave birth (N=100) were tested few days after delivery. Measures of handedness, infant holding-side preferences, and level of depressive symptoms expressed by mothers (assessed with the CES-D scale) were collected via questionnaires. Asymmetries in emotional perception were assessed via a Chimeric Figure Task and a Dichotic Listening Task. Results showed that breastfeeding (1) reduced left-side bias for holding newborns and (2) was associated with lowest levels of depressive symptoms. Moreover, holding biases were related to maternal depression in bottle-feeding but not in breastfeeding mothers, namely that holding on the right-side while bottle-feeding was associated with higher levels of depressive symptoms. These results were not due to hemispheric specialization as auditory and visual asymmetries were similar between breastfeeding and bottle-feeding mothers. The discussion emphasizes the striking role of the early mother/child relationship's establishment on infant holding biases.     

SPACE AND RELIGION: AN INTERWEAVING OF INFLUENCES

Since the earliest ages of humanity, the contemplation of the starry sky has invited the human being to ask: “Who am I? Where is my origin? What is my destiny?” The revolution introduced by modem astronomy has affected how humankind understands itself, and the development of aeronautical and then astronautical techniques introduced a new experiment for humanity—that of being citizen of the sky. By carrying out the dream of Icarus, has humanity realized the attempt of Prometheus? Would we take the place of the gods or God? Do religions have to fear the conquest of space? Despite modern science and the knowledge we have accumulated, space still holds its share of mystery, nurtured by its vast dimensions and startling beauty. Space continues to raise the issue of meaning.     

Effect of arousal on internal clock speed in real action and mental imagery.

The possible implication of an internal clock as a mechanism accounting for the temporal homology between actual and mental walking is studied. To observe this phenomenon, stressful sound stimuli were used to increase arousal, which is known to activate the internal clock. Seventeen participants performed three tasks: (1) a time production task, used as a reference task reflecting the internal clock speed; (2) an actual walking task; and (3) a mental walking task, all three in two sound conditions (no noise and noise). The results showed a significant effect of arousal on time in each task. The effect of noise, increasing the arousal level, was greater in time production and mental imagery tasks than in real action. In addition, the percentages of change between the two sound conditions for actual and mental walking time were not statistically different. These findings are further evidence of the existence of a timing process common to actual and mental walking. The data are consistent with the implication of an internal clock in both actual and mental walking.     

What Criminals’ Tattoos Symbolize: Drawing on Darwin,Durkheim, and Lombroso

Criminals’ tattoos have many meanings. A limitation of prior research is that these meanings have not been organized into an elegant yet exhaustive typology that is theoretically informed. To address that gap, this article analyzes “Russian criminal tattoos” in light of classic conceptions of tattoos—namely those of Darwin, Durkheim, and Lombroso. The benefits of the analysis include (1) an expanded conception of what tattoos symbolize from Darwinian and Durkheimian perspectives and (2) the formation of a simple but comprehensive typology of what criminals’ tattoos represent. The article concludes by considering implications for future research.     

With a Little Help From Adults: Positive Emotion as an Excuse for Underage Drinking

This study provides an empirical demonstration that people’s reaction to youth drinking are influenced by the alleged motive for drinking and that regulations can easily be violated as soon as the perceived motive for underage liquor drinking is a positive emotion. The study solicited 432 passersby (50% men) to buy hard liquor for a female confederate allegedly younger than the minimum legal drinking age in France. Results showed that participants complied more frequently with the request when the motive for drinking was related with positive emotion.     

Memory distortion: an adaptive perspective

Memory is prone to distortions that can have serious consequences in everyday life. Here we integrate emerging evidence that several types of memory distortions - imagination inflation, gist-based and associative memory errors, and post-event misinformation - reflect adaptive cognitive processes that contribute to the efficient functioning of memory, but produce distortions as a consequence of doing so. We consider recent cognitive and neuroimaging studies that link these distortions with adaptive processes, including simulation of future events, semantic and contextual encoding, creativity, and memory updating. We also discuss new evidence concerning factors that can influence the occurrence of memory distortions, such as sleep and retrieval conditions, as well as conceptual issues related to the development of an adaptive perspective.     

The temporal distribution of autobiographical memory: changes in reliving and vividness over the life span do not explain the reminiscence bump

When autobiographical memories are elicited with word cues, personal events from middle childhood to early adulthood are overrepresented compared to events from other periods. It is, however, unclear whether these memories are also associated with greater recollection. In this online study, we examined whether autobiographical memories from adolescence and early adulthood are recollected more than memories from other lifetime periods. Participants rated personal events that were elicited with cue words on reliving or vividness. Consistent with previous studies, most memories came from the period in which the participants were between 6 and 20 years old. The memories from this period were not relived more or recalled more vividly than memories from other lifetime periods, suggesting that they do not involve more recollection. Recent events had higher levels of reliving and vividness than remote events, and older adults reported a stronger recollective experience than younger adults.     

A dynamic computational model of employees goal transformation: Using self-determination theory

Following self-determination theory, this paper investigates the relations of employees’ perceptions of supervisors’ autonomy-supportive or controlling environments to their intrinsic or extrinsic work goals using both a field study and a computational dynamics model (Vancouver and Weinhardt in Org Res Methods 15(4):602–623, 2012), which is a recent and innovative technique. In Study 1, we did an empirical study with 128 employees over a half-year period and found that employees’ perceptions of supervisors’ autonomy-supportive environments satisfied employees’ basic psychological needs and promoted their intrinsic goals; controlling environments frustrated their basic needs and promoted their extrinsic goals. In Study 2, we used a system dynamics model to simulate the change in employees’ extrinsic goals, and the results showed that perceptions of supervisors’ autonomy-supportive environments related to the transformation of employees’ extrinsic goals. The study contributes by demonstrating that employees’ perception of supervisors’ environments could be a reason for employees’ different goal orientations, and it contributes by simulating the use of the dynamic process of goal transformation in research.
