Sociolinguistic inference and intercultural coorientation.

We present a model that examines the effects of cultural differences on coorientation (the ability of communicators to accurately encode and interpret the referential and relational meanings of messages). Intercultural coorientation is made problematic by the absence of certain shared communication system knowledge, which in same‐culture interactions is used in the dynamic sociolinguistic negotiation of relational rights and obligations. We propose that the process of sociolinguistic negotiation of meanings relies fundamentally on probabilistic inference and have constructed a model based on Bayes' theorem. The model predicts the effects of the communication situation, communicator stereotypes and prejudice, and some other‐culture speaker errors on conclusions the receiver draws about the message. Using the model, we distinguish between the ethnocentric error of interpreting a communication in terms of one's own culture and the error of not seeing the communication as diagnostic. Among our predictions are: (a) the less diagnostic the communication, the more impact cultural stereotypes will have on attributions; (b) although evidence of sociolinguistic incompetence sometimes causes misunderstanding, it sometimes prevents misunderstanding; (c) multiple consistent features make intentions clearer than would a single cue, but multiple features violating co‐occurrence norms often lead to the attribution of incompetence.     

Influence of age, sex, hearing loss, and balance on development of sidearm striking by deaf children

131 deaf boys and girls were evaluated on development of the sidearm striking pattern. Mature form in this skill was related to chronological age and to proficiency in balance. Sex and hearing loss do not appear to influence development of this skill.     

Children's academic attainment is linked to the global organization of the white matter connectome

Literacy and numeracy are important skills that are typically learned during childhood, a time that coincides with considerable shifts in large‐scale brain organization. However, most studies emphasize focal brain contributions to literacy and numeracy development by employing case‐control designs and voxel‐by‐voxel statistical comparisons. This approach has been valuable, but may underestimate the contribution of overall brain network organization. The current study includes children (N = 133 children; 86 male; mean age = 9.42, SD = 1.715; age range = 5.92–13.75y) with a broad range of abilities, and uses whole‐brain structural connectomics based on diffusion‐weighted MRI data. The results indicate that academic attainment is associated with differences in structural brain organization, something not seen when focusing on the integrity of specific regions. Furthermore, simulated disruption of highly‐connected brain regions known as hubs suggests that the role of these regions for maintaining the architecture of the network may be more important than specific aspects of processing. Our findings indicate that distributed brain systems contribute to the etiology of difficulties with academic learning, which cannot be captured using a more traditional voxel‐wise statistical approach.     

Lexically guided retuning of letter perception

Participants made visual lexical decisions to upper-case words and nonwords, and then categorized an ambiguous N-H letter continuum. The lexical decision phase included different exposure conditions: Some participants saw an ambiguous letter "?", midway between N and H, in N-biased lexical contexts (e.g., REIG?), plus words with unambiguous H (e.g., WEIGH); others saw the reverse (e.g., WEIG?, REIGN). The first group categorized more of the test continuum as N than did the second group. Control groups, who saw "?" in nonword contexts (e.g., SMIG?), plus either of the unambiguous word sets (e.g., WEIGH or REIGN), showed no such subsequent effects. Perceptual learning about ambiguous letters therefore appears to be based on lexical knowledge, just as in an analogous speech experiment (Norris, McQueen, & Cutler, 2003) which showed similar lexical influence in learning about ambiguous phonemes. We argue that lexically guided learning is an efficient general strategy available for exploitation by different specific perceptual tasks.     

Reconsidering Relativistic Causality

I discuss the idea of relativistic causality, i.e., the requirement that causal processes or signals can propagate only within the light‐cone. After briefly locating this requirement in the philosophy of causation, my main aim is to draw philosophers’ attention to the fact that it is subtle, indeed problematic, in relativistic quantum physics: there are scenarios in which it seems to fail.

I set aside two such scenarios, which are familiar to philosophers of physics: the pilot‐wave approach, and the Newton–Wigner representation. I instead stress two unfamiliar scenarios: the Drummond–Hathrell and Scharnhorst effects. These effects also illustrate a general moral in the philosophy of geometry: that the mathematical structures, especially the metric tensor, that represent geometry get their geometric significance by dint of detailed physical arguments.     

The preference to work for a man or a woman: A matter of sex and gender?

A survey of 455 individuals sampled from two populations that varied in age, educational level, and work experience posed a question asked in Gallup polls over six decades: “If you were taking a new job and had your choice of a boss, would you prefer to work for a man or a woman?” Respondents could state that they would prefer a male boss, prefer a female boss, or had no preference. As expected from theory and Gallup results, respondents who had a preference preferred to work for a man more than a woman, although a majority expressed “no preference.” When they expressed a preference, women preferred to work for a female boss over a male boss more than men did, whereas men preferred to work for a male boss over a female boss more than women did. Sex-typed (i.e., masculine or feminine) respondents in gender identity exhibited a greater preference to work for a boss of a particular sex over having no preference than non-sex-typed respondents. Further, feminine respondents preferred to work for a female boss over a male boss more than masculine respondents did, whereas masculine respondents preferred to work for a male boss over a female boss more than feminine respondents did. Overall, these results suggest that the preference to work for a man or a woman is a matter of both sex and gender. Implications for job applicants' vocational decisions and how female leaders fare in the workplace are discussed.     

Mangy mutt or furry friend? Anthropomorphism promotes animal welfare

Recent research has demonstrated that people have an affinity for non-human entities that appear to have human qualities. The current studies build on this research, examining whether anthropomorphism can be used to promote animal welfare. In Study 1 (n = 42), participants read scenarios about dogs and reported more willingness to help the ones described with anthropomorphic language relative to those described with non-anthropomorphic language. In Study 2 (n = 57), participants rated dogs on either human or canine characteristics (e.g., good listener vs. good at listing to commands). Relative to the non-anthropomorphism condition, participants in the anthropomorphism condition reported more willingness to adopt dogs from a shelter, and more support for animal rights, animal welfare, and vegetarian and vegan attitudes. Moreover, these pro-animal attitudes fully mediated the effect of the anthropomorphism manipulation on willingness to adopt the dogs.     

Age and sex differences in object control skills by children ages 5 to 14

Object control skills provide children the tools to be physically active-a major societal priority. At the fundamental movement level, object control skills form the foundation of further sports skill development. The purpose of this study was to examine children's (ages 5 to 14 years, Grades K-8) development of four key object control skills: catching, throwing, kicking, and striking. 186 children were tested on selected items from the Object Control Subtest of the Test of Gross Motor Development-2, using a cross-sectional and correlational design. As anticipated, significant differences were found for age on all four skills. These improvements were characterized by early, rapid gains at ages 9 to 10, beyond which development occurred at a slower rate for catching, throwing, and kicking; striking development continued at a steady rate to age 14 years. Contrary to previous findings, no overall sex differences were found for catching or kicking. Overall sex differences favoring boys were observed for throwing and striking. Implications for evolutionary contributions to throwing and striking were discussed.
