The development of an organized sleep–wake cycle in young infants is influenced by characteristics of both the infant and the parent, and by the nature of their dyadic interaction. Sleep–wake state organization is influenced first by homeostatic biological regulation, and later by socioemotional regulation. This report describes a feasibility study using an olfactory intervention designed to bridge the transition from physiologic to social regulation in sleep–wake state organization. A sample of 21 mother–infant dyads participated in an one year longitudinal study, after random assignment to either an experimental condition with a maternal odor-laden sleepaid, representational sleepaid (RSA) or a control condition with a neutral sleepaid, Sham Control (SC). Self-report questionnaires measured maternal psychological well-being, and video taping recorded infant sleep–wake behaviors repeatedly throughout the first year. RSA mothers reported significantly better levels of well-being throughout the year. At six and twelve months, mothers who reported more depressive feelings exhibited different nighttime interaction patterns. Infant sleep–wake state organization and sleepaid use changed significantly during the first year but were not altered by the intervention. © 1997 Michigan Association for Infant Mental Health 相似文献

The automatically reinforced self-injury of a girl with autism was treated by providing noncontingent access to a single set of preferred toys during 30-min sessions. The reductive effects of the intervention waned as the session progressed. Rotating toy sets after 10 min or providing access to multiple toy sets resulted in reductions that lasted the entire 30 min. 相似文献

Let S denote the variety of Sugihara algebras. We prove that the lattice (K) of subquasivarieties of a given quasivariety K
S is finite if and only if K is generated by a finite set of finite algebras. This settles a conjecture by Tokarz [6]. We also show that the lattice (S) is not modular. 相似文献

The Importance of Item Selection in "Knew-It-All-Along" Studies of General Knowledge 总被引:1,自引:0,他引:1
Anders Winman 《Scandinavian journal of psychology》1997,38(1):63-72
This study was designed to investigate the effects of item sampling on hindsight bias in experiments using general knowledge material. The results show that the use of random versus traditional experimenter-selected item samples can have different effects on hindsight bias. In a within-subjects study almost twice as many items in a random sample were connected with a reversed effect rather than with a traditional hindsight bias. The same items that resulted in overconfidence in foresight lead to a higher degree of hindsight bias than others. The results suggest that earlier findings of unusually large hindsight effects with general knowledge tasks may be explained by the selection of items used. No hindsight effect was found on confidence scores in a within-subjects design, but was obtained in a between-subjects design. Results suggest that the use of a within-subjects design itself can moderate hindsight bias by familiarizing subjects with the task. The study shows the importance of two conditions for decreasing the hindsight bias: (1) The use of randomly sampled items, and (2) The use of a within-subjects procedure. When these conditions were met, the "knew-it-all-along effect" was completely eliminated. 相似文献

We study modal logics in the setting of varieties of modal algebras. Any variety of modal algebras generated by a finite algebra — such, a variety is called tabular — has only finitely many subvarieties, i.e. is of finite height. The converse does not hold in general. It is shown that the converse does hold in the lattice of varieties of K4-algebras. Hence the lower part of this lattice consists of tabular varieties only. We proceed to show that there is a continuum of pretabular varieties of K4-algebras — those are the non-tabular varieties all of whose proper subvarieties are tabular — in contrast with Maksimova's result that there are only five pretabular varieties of S4-algebras. 相似文献

Measures of relatedness of odours were obtained by means of two psychophysical methods and one electrophysiological technique. The psychophysical data consisted of similarity judgments and confusion measures. The electrophysiological data were based upon statistical treatment of the responses of single units in the olfactory bulb of the frog. Significant rank correlations were obtained between the results of the three methods. The significance of psychological relatedness data for the study of basic receptor processes is discussed. 相似文献

The Impact of Gender on the Review of the Curricula Vitae of Job Applicants and Tenure Candidates: A National Empirical Study 总被引:1,自引:0,他引:1
The purpose of this study was to determine someof the factors that influence outside reviewers andsearch committee members when they are reviewingcurricula vitae, particularly with respect to the gender of the name on the vitae. The participants inthis study were 238 male and female academicpsychologists who listed a university address in the1997 Directory of the American PsychologicalAssociation. They were each sent one of four versions of acurriculum vitae (i.e., female job applicant, male jobapplicant, female tenure candidate, and male tenurecandidate), along with a questionnaire and aself-addressed stamped envelope. All the curricula vitaeactually came from a real-life scientist at twodifferent stages in her career, but the names werechanged to traditional male and female names. Althoughan exclusively between-groups design was used to avoidsparking genderconscious responding, the resultsindicate that the participants were clearly able todistinguish between the qualifications of the jobapplicants versus the tenure candidates, as evidenced bysuggesting higher starting salaries, increasedlikelihood of offering the tenure candidates a job,granting them tenure, and greater respect for theirteaching, research, and service records. Both men andwomen were more likely to vote to hire a male jobapplicant than a female job applicant with an identicalrecord. Similarly, both sexes reported that the male job applicant had done adequate teaching,research, and service experience compared to the femalejob applicant with an identical record. In contrast,when men and women examined the highly competitive curriculum vitae of the real-life scientist whohad gotten early tenure, they were equally likely totenure the male and female tenure candidates and therewas no difference in their ratings of their teaching, research, and service experience. There was nosignificant main effect for the quality of theinstitution or professional rank on selectivity inhiring and tenuring decisions. The results of this study indicate a gender bias for both men and womenin preference for male job applicants. 相似文献

The Perceptual Pathway: Tracing the Mechanisms of Political Value Transfer across Generations 总被引:1,自引:0,他引:1
Anders Westholm 《Political psychology》1999,20(3):525-551
The transfer of political values across generations is commonly understood as a two-step process. First, the child perceives the characteristics of the parent, thereby creating an image of what the parent is like. Second, the child is persuaded to adapt his or her own views to that image. Despite its theoretical dominance, the details of this perceptual pathway of parentalsocialization have rarely been examined empirically. A major Swedish socialization study offers unusually good opportunities to investigate how it actually operates. The results indicate that the perceptual pathway as a whole is of great but not universal significance, that perception is more important than persuasion because of its greater variability, and that the conditions regulating the former are distinct from those regulating the latter. One implication of the results is that studies of interpersonal influence based on a single source (e.g., the child alone) are likely to yield a very lopsided view of the socialization process. 相似文献
