Agreement among teacher,peer, and self-ratings of children's aggression,withdrawal, and likability

This study examined the relationship among teacher, peer, and self-ratings of children's social behavior. The Pupil Evaluation Inventory was completed by 172 first-graders, 346 fourth-graders, 283 seventh-graders, and 30 teachers. Groups of deviant responders and controls were also selected from the total sample on the basis of peer-rated aggression and withdrawal scores. Interrater agreement was consistently greater between peer and teacher ratings than between self-ratings and either peer or teacher ratings. Discrepancies between raters were greatest for children with more deviant scores, with peer ratings providing the highest estimates of deviant behavior, and self ratings yielding the lowest. Self ratings were lower than teacher or peer ratings on aggression and withdrawal, and higher on likability. Aggression produced greatest agreement between raters. Agreement was uninfluenced by the cognitive maturity of peer evaluators. The results suggest that the selection of raters should be influenced by the class of behaviors to be evaluated and the context in which they occur.This research was funded by Québec Ministry of Social Affairs Grant RS 281 to Jane Ledingham and Alex Schwartzman.

THE QUESTIONABLE UNITY OF THE CONCRETE OPERATIONS STAGE

This study was designed to investigate the reported capacity of some non-conservers of weight to deal successfully with tasks involving multiple classification. Tests of seriation, class inclusion, conservation of quantity, weight and volume, and eight multiple classification tasks (after Inhelder and Piaget) were given to 49 recently immigrated Yugoslav children (median age 10.5 years) in Australian primary schools, using Serbo-Croat as the language of administration. Performance on most of these tests of concrete operational behaviour was found to be about two years retarded as compared with Genevan data. On seven of the eight multiple classification tasks, not less than one-third of non-conservers of weight were able to give operational solutions. No differences were found in this group of 22 non-conservers, in terms of success vs. non-success in multiple classification, in age, sex, urban/rural domicile of origin, more/less recent arrival in Australia, or Macedonian/Serbian ethnicity. It is concluded that a case can be made for not regarding the concrete operations stage as a formal unity, but instead (following Flavell and Wohlwill) as a set of structures without necessary interdependence.     

Judgments of grammaticality of sentences with a differing number of arguments: a comparison of English and Japanese speakers

This study explored native speakers' linguistic intuition as revealed in judging the grammaticality of sentences. Speakers of English (n = 36) and Japanese (n = 57) judged the relative grammaticality of sentences involving a verb which occurred together with one, two or three arguments. Findings showed that English speakers were more affected by the number of arguments in sentences. They judged sentences having three arguments as grammatical most often and ones having one or two arguments as grammatical less often. However, Japanese speakers gave rather similar and more grammatical judgments regardless of the number of arguments in sentences. The findings indicate a difference in tightness of argument structure in the two languages even when the sentences judged are simple sentences and they are given without any sentential context.     

Against Particle/Field Duality: Asymptotic Particle States And Interpolating Fields In Interacting Qft (Or: Who's Afraid Of Haag's Theorem?)

This essay touches on a number of topics in philosophy of quantum field theory from the point of view of the LSZ asymptotic approach to scattering theory. First, particle/field duality is seen to be a property of free field theory and not of interacting QFT. Second, it is demonstrated how LSZ side-steps the implicationsof Haag's theorem. Finally, a recent argument due to Redhead (1995), Malament (1996) and Arageorgis (1995) against the concept of localized particle states is addressed. Briefly, the argument observes thatthe Reeh–Schlieder theorem entails that correlations between spacelike separatedvacuum expectation values of local field operators are always present,and this, according to the above authors, dictates against the notion of a localizedparticle state. I claim that this moral is excessive and that a coherentnotion of localized particles is given by the LSZ approach. The underlyingmoral to be drawn from this analysis is that questions concerning theontology of interacting QFT cannot be appropriately addressed if one restrictsoneself to the free theory.     

Comparing parents' perceptions of IVF conceived children's behavior with naturally conceived children

Conception after assisted reproductive methods is associated with considerable emotional as well as physical stress. Parents often have to wait ten years or more before conceiving. As part of an ongoing U.K. study, we assessed 140 intracytoplasmic sperm injection (ICSI) conceived children and 101 naturally conceived control children via parental completion of the Eyberg Child Behaviour Inventory when their children were two years old. Parents of children conceived after assisted reproductive methods reported fewer behavioral problems. Implications for long‐term development are discussed. ©2004 Michigan Association for Infant Mental Health.     

Advertisement–programme congruence in memory of sexual fragrance advertisements

The current study explored the effect of sexual content in advertisements and the programme–advertisement congruence on the memory of sexual and nonsexual advertisements. Seventy participants (41 females and 29 males) were randomly allocated to one of four conditions. They viewed either The Bachelorette (sexual programme) or I'm a Celebrity… Get Me Out of Here! (nonsexual programme) with sexual or nonsexual fragrance advertisements placed within the programme. The order of the advertisements was counterbalanced across participants to control for order effects. Free and cued recall of the advertisements were assessed. As predicted, there was a main effect of advertisement type, with the sexual advertisements better recalled than the nonsexual advertisements. Contrary to our prediction, the sexual content of the programme did not have an effect on advertisement recall. There was an interaction between the advertisement type and programme type; sexual advertisements were remembered better when embedded within a sexual programme. Limitations of this study are considered.
