On the learnability of frequent and infrequent word orders: An artificial language learning study

Most languages have a basic or "canonical" word order, which determines the relative positions of the subject (S), the verb (V), and the object (O) in a typical declarative sentence. The frequency of occurrence of the six possible word orders among world languages is not distributed uniformly. While SVO and SOV represent around 85% of world languages, orders like VSO (9%) or OSV (0.5%) are much less frequent or extremely rare. One possible explanation for this asymmetry is that biological and cognitive constraints for structured sequence processing make some word orders easier to be processed than others. Therefore, the high frequency of these word orders would be related to their higher learnability. The aim of the present study was to compare the learnability of different word orders between groups of adult subjects. Four artificial languages with different word orders were trained: two frequent (SVO, SOV) and two infrequent (VSO, OSV). In a test stage, subjects were asked to discriminate between new correct sentences and syntax or semantic violations. Higher performance rates and faster responses were observed for more frequent word orders. The results support the hypothesis that more frequent word orders are more easily learned.     

The willingness of medical students to use Facebook as a training channel for professional habits: the case of influenza vaccination

The low acceptance of influenza vaccination by both medical students and healthcare workers (HCWs) signals the need for innovative strategies. We administered an anonymous questionnaire to 410 University of Barcelona medical students who were asked about using the Internet to find information on influenza vaccination of HCWs and about their willingness to use technical and informal Facebook pages as an information channel on this topic. Of the 410 participants, 74.1 percent were female and 58.3 percent were in the first preclinical 3-year university cycle. A total of 7.6 percent participants reported using the Internet for queries on influenza vaccination, 89.8 percent reported that they were Facebook users, and 275 (67.1 percent) would accept an invitation from the technical or informal Facebook pages. The technical Web site would be actively followed by 77, or by 30.0 percent of those who would accept the invitation and the informal site by 116 (43.6 percent of those who would accept). The marked willingness to use Facebook to obtain information on the influenza vaccination of HCWs potentially opens a new window in health education: social networks could be used to help create professional habits. Students would be more likely to engage with this type of Facebook page if the contents were informal rather than highly technical.     

Effect of ingroup membership on organizational meta-representation

The present study considers the importance of analyzing what very powerful or influential people think about their employees. We assumed that belonging to a specific category has a differential effect on the perception of others' thoughts in the organization ("meta-representation"). Therefore, experts in organization and human resources from diverse organizations and institutions assessed seven dimensions which structure the organizational image (context, structure, organizational processes, working climate, culture, satisfaction and efficacy). The results showed that belonging to a group (managers or leaders, academicians, consultants, technicians or employees' representatives) modulated the meta-representation, as the experts' opinion about what they think that the employees consider important was related to their group. This was specifically the case for the managers' and leaders' representations, which differed from the other groups and especially from that of the technicians and employees' representatives. The implications of the present findings are discussed.     

The Division of Household Labor in Spanish Dual Earner Couples: Testing Three Theories

Although the participation of men in household activities has increased, this has not prompted an equitable division of household activities among men and women, since Spanish women continue to perform a greater share of these activities than Spanish men. This article explores the explanatory potential of three theoretical approaches (traditional gender division, role-strain and the resource-bargaining approach) to account for the emergence of different patterns in the division of unpaid work among Spanish dual earner couples. Using a representative sample of 2,877 Spanish workers and through logit ordered models, our study reveals that the three models contribute to the explanation of the different patterns of household labor and, therefore, may be regarded as complementary.     

Using self-determination theory to explain sport persistence and dropout in adolescent athletes

Motivational characteristics are influential in shaping adolescents' desire to persist in sport or to discontinue their sport participation. Self-determination theory (Deci & Ryan, 2000) was utilized as the theoretical framework for this study. This theory examines whether sustained participatory involvement, defined as continued participation in the sport through the next year, was influenced by individuals' self-determined motivation and by the fulfillment of the three basic psychological needs of autonomy, competence, and relatedness. Four hundred ninety two soccer players between the ages of 13 and 17 years comprised the sample. Results indicated sport dropout was explained by higher levels of amotivation, external regulation, and introjected regulation and by lower satisfaction of relatedness and autonomy needs. The findings of this study contribute to the knowledge base on sport dropout as they supported many of self-determination theory.     

Phonological mediation in visual masked priming: evidence from phonotactic repair

In a series of 4 experiments, the authors show that phonological repair mechanisms, known to operate in the auditory modality, are directly translated in the visual modality. This holds with the provision that printed stimuli are presented for a very brief duration and that the effect of phonological repair is tested after a delay of some 100 ms has elapsed after that presentation. The case of phonological repair chosen to exemplify the parallelism between print and speech is the prosthesis of /e/ in utterances beginning with /s/ followed by a consonant in Spanish. Native speakers of Spanish hear a prothetic /e/ in auditorily presented pseudowords such as special (/speojal/, derived from "especial") as well as stuto (/stuto/, derived from "astuto"). It is shown here that they also hear that same vowel /e/ when presented with the printed pseudowords "special" and "stuto." This finding of a phonological repair effect in print has implications for the issue of phonological activation from print, as well as for the prelexical locus and mandatory nature of phonological repair mechanisms in general.     

Intra-female aggression in the mouse (Mus musculus domesticus) is linked to the estrous cycle regularity but not to ovulation

Intraspecific communication between mice takes place mainly via urinary chemosignals or "pheromones". Pheromones can influence aggressive and reproductive behavior as well as the neuroendocrine condition of the recipient female mice via their olfactory system. In this study, reproductively cyclic mice in the estrus phase were used to test intraspecific agonistic aggressive behavior. Data were obtained also on the count of the eggs shed in the oviducts. The results showed that (i) individually housed female mice are more aggressive toward an intruder female mouse than grouped mice, (ii) mice in which the vomeronasal organ was removed show aggressive behavior intermediate between individually housed and grouped mice, and (iii) a within group analysis did not show a positive correlation between aggression and presence of shed eggs in the oviducts.     

Observing the therapeutic alliance in family therapy: associations with participants' perceptions and therapeutic outcomes

Positive and negative alliance‐related behaviours of thirty‐seven families seen in brief family therapy were rated from videotapes using the System for Observing Family Therapy Alliances ( Friedlander et al., 2006b ). Positive associations were found between in‐session behaviour and participants' perceptions of the alliance and improvement so far both early (session 3) and later in therapy (session 6). Binary logistic regression showed that successful outcomes (defined as consensus by therapist and all family members on general improvement and reduced problem severity) were significantly predicted by positive individual behaviour (Engagement in the Therapeutic Process, Emotional Connection with the Therapist, Safety within the Therapeutic System) in session 3 and productive within‐family collaboration (Shared Sense of Purpose within the Family) in session 6. Shared Sense of Purpose was the alliance indicator most consistently associated with clients' and therapists' perceptions of therapeutic progress; moreover, it was the only alliance indicator to improve significantly over time in treatment.     

Emotional scenes in peripheral vision: selective orienting and gist processing, but not content identification

Emotional-neutral pairs of visual scenes were presented peripherally (with their inner edges 5.2 degrees away from fixation) as primes for 150 to 900 ms, followed by a centrally presented recognition probe scene, which was either identical in specific content to one of the primes or related in general content and affective valence. Results indicated that (a) if no foveal fixations on the primes were allowed, the false alarm rate for emotional probes was increased; (b) hit rate and sensitivity (A') were higher for emotional than for neutral probes only when a fixation was possible on only one prime; and (c) emotional scenes were more likely to attract the first fixation than neutral scenes. It is concluded that the specific content of emotional or neutral scenes is not processed in peripheral vision. Nevertheless, a coarse impression of emotional scenes may be extracted, which then leads to selective attentional orienting or--in the absence of overt attention--causes false alarms for related probes.     

Quantification over Sets of Possible Worlds in Branching-Time Semantics

Temporal logic is one of the many areas in which a possible world semantics is adopted. Prior's Ockhamist and Peircean semantics for branching-time, though, depart from the genuine Kripke semantics in that they involve a quantification over histories, which is a second-order quantification over sets of possible worlds. In the paper, variants of the original Prior's semantics will be considered and it will be shown that all of them can be viewed as first-order counterparts of the original semantics.
