Children learn words easier when they are interested in the category to which the word belongs

The overall pattern of vocabulary development is relatively similar across children learning different languages. However, there are considerable differences in the words known to individual children. Historically, this variability has been explained in terms of differences in the input. Here, we examine the alternate possibility that children's individual interest in specific natural categories shapes the words they are likely to learn – a child who is more interested in animals will learn a new animal name easier relative to a new vehicle name. Two‐year‐old German‐learning children (N = 39) were exposed to four novel word–object associations for objects from four different categories. Prior to the word learning task, we measured their interest in the categories that the objects belonged to. Our measure was pupillary change following exposure to familiar objects from these four categories, with increased pupillary change interpreted as increased interest in that category. Children showed more robust learning of word–object associations from categories they were more interested in relative to categories they were less interested in. We further found that interest in the novel objects themselves influenced learning, with distinct influences of both category interest and object interest on learning. These results suggest that children's interest in different natural categories shapes their word learning. This provides evidence for the strikingly intuitive possibility that a child who is more interested in animals will learn novel animal names easier than a child who is more interested in vehicles.     

Conflict of interest from a Romanian geneticist’s perspective

This paper examines Romanian bioethics regulations for biomedical sciences, looking in particular at the genetics area as a source for conflict of interest. The analysis is focused on the organizational level, national regulations, the sources for generating conflicts of interest, and management of conflicts. Modern biotechnology and gene technology are among the key technologies of the twenty-first century. The application of gene technology for medical and pharmaceutical purposes is widely accepted by society, but the same cannot be said of the development and application of gene technology in agriculture and food processing. Because the use of a technology in the production and processing of food is regarded more sceptically than in the production of biomedical products, there can be areas of conflict in many cases when communication is undertaken about gene technology in the agro-food sector. Ethical concerns play an important factor in this, but a society’s attitude to a developing technology is an amalgam of many effects which are beyond ethics as such. This paper contains a study carried out by the author for the Romanian Association for Consumer Protection about the attitudes of consumers towards genetically modified (GM) foods. This study revealed that in Romania more than 98% of consumers did not know anything about GM foods and frequently were confused about the definitions of these terms. In conclusion, it is necessary to say that there is a low level of knowledge regarding biotechnology in Romania and this is an important reason why there is neither public acceptance of gene technology products nor is there a rejection.

Conflicts of interest in science and medicine: the physician's perspective

The various statements and declarations of the World Medical Association that address conflicts of interest on the part of physicians as (1) researchers, and (2) practitioners, are examined, with particular reference to the October 2000 revision of the Declaration of Helsinki. Recent contributions to the literature, notably on conflicts of interest in medical research, are noted. Finally, key provisions of the American Medical Association’s Code of Medical Ethics (2000–2001 Edition) that address the various forms of conflict of interest that can arise in the practice of medicine are outlined. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002. The World Medical Association (WMA) is a global federation of National Medical Associations representing the millions of physicians worldwide. Acting on behalf of patients and physicians, the WMA endeavours to achieve the highest possible standards of medical care, ethics, education and health-related human rights for all people.     

The assumed effects of positive feedback paired with success on motivation to do a task: The cases of characters with high and low initial levels of interest

This study investigated the effects of positive feedback paired with success on motivation to do a task, and examined whether this differed according to whether the person performing the task had a high or low initial level of interest in that task. Subjects (448 junior college students) were asked to rate (from 0–10) the level of motivation of characters in four different stories. Subjects believed that positive feedback would encourage the character to do a task regardless of initial level of interest. However, when positive feedback could not be expected, ratings for motivation fell. Ratings for motivation were further analyzed when no positive feedback could be expected, either after an earlier experience of positive feedback paired with success or after success only (no feedback). In the case of a low initial level of interest, it was assumed that motivation would be increased after positive feedback, but in the case of a high initial level of interest motivation was assumed to be decreased by an earlier experience of positive feedback paired with success. These results suggest that the effect of positive feedback paired with success will differ according to the level of a person's initial interest.     

Consonances and controversies: Investigation and its discontents revisited

The author responds to the commentaries of 13 experts on his 1980 American Psychologist article, “Investigation and its discontents: On some constraints on progress in psychological research.” Among the themes addressed are the role of theory in psychological research, the meanings and implications of “productivity” by scholars and researchers, the role of grants, and of money in general, in directing research efforts, and the relation between psychological and neuropsychological research.     

Why psychology needs conceptual analysts: Wachtel's “discontents” revisited

Commenting on Wachtel's “Investigation and its Discontents” [Wachtel, P. L. (1980). Investigation and its discontents: Some constraints on progress in psychological research. American Psychologist, 35, 399–408], I agree that lack of support for a career path of conceptual analysis and critique is a serious problem. Psychology requires a strong conceptual component because it is subject to unusual distortions and self-deceptions in theory formation and evidential evaluation due to issues of power, self-esteem, and social ideology. I agree with Wachtel that pressures for quantity of publication are detrimental to scientific quality, but dispute his suggestion that excessive focus on quantity in assessing productivity can be addressed by having tenure and promotion candidates submit only their three best papers. Such reviews must be based on the entire record, so improvements must involve journals’ acceptance standards. Regarding Wachtel's concern about the influence of grants on reviews, I argue that grants should be relevant only to the extent they bear on the candidate's scholarly goals.     

医生与药业的关系：利益冲突重要根源

药业与医生的关系在最近40年日益受到医学界与社会的重视。药业以并不昂贵的馈赠及其他手段,资助学术交流、医学教育和医学研究,深刻地影响着临床医生的行为和诊治决策,从而危及医学的科学性和医学职业精神,加重了病人的负担,且祸及病人健康。药业与医生的这种关系,是道德与金钱关系的赤裸表现,是资本对医学的无情侵略。从道德、法律、行业管理等诸多方面正确规范行业与医生的相互关系,避免当前面临的种种弊端,维护医学的科学性,保护病人与社会公众的利益,刻不容缓。     

Are Newborns Morally Different from Older Children?

Policies and position statements regarding decision-making for extremely premature babies exist in many countries and are often directive, focusing on parental choice and expected outcomes. These recommendations often state survival and handicap as reasons for optional intervention. The fact that such outcome statistics would not justify such approaches in other populations suggests that some other powerful factors are at work. The value of neonatal intensive care has been scrutinized far more than intensive care for older patients and suggests that neonatal care is held to a higher standard of justification. The relative value placed on the life of newborns, in particular the preterm, is less than expected by any objective medical data or any prevailing moral frameworks about the value of individual lives. Why do we feel less obligated to treat the premature baby? Do we put newborns in a special and lesser moral category? We explore this question from a legal and ethical perspective and offer several hypotheses pertaining to personhood, reproductive choices, “precious children,” and probable evolutionary and anthropological factors.     

Assessing vocational interests in the Basque Country using paired comparison design

This article proposes the Thurstonian paired comparison model to assess vocational preferences and uses this approach to evaluate the Realistic, Investigative, Artistic, Social, Enterprise, and Conventional (RIASEC) model in the Basque Country (Spain). First, one unrestricted model is estimated in the Structural Equation Modelling framework using one paired comparison design. Secondly, the RIASEC circumplex structure is evaluated upon the estimated latent preferences correlation matrix. The results show good fit between the Thurstonian model and the data, but do not confirm the RIASEC structure in the Basque population.     

Use of Self-perspectives and their Sources to Predict the Mathematics Enrollment Intentions of Girls and Boys

An understanding of the differences in the ways in which self-efficacy and interest influence boys’ and girls’ intentions to continue enrollment in mathematics courses may provide insight into how to encourage continued mathematics enrollment for all students. Two competing theoretical models of mathematics self-efficacy and interest in predicting students’ enrollment intentions and achievement were evaluated separately across samples of middle level boys and girls. One model was empirically supported for both groups and indicated the independent influence of self-efficacy and interest in predicting enrollment intentions. Multi-group analyses revealed that self-efficacy’s influence in enrollment intentions and achievement was significantly stronger for boys than for girls, and interest was significantly more important in the prediction of enrollment intentions for girls than for boys.
