Maternal well-being and sleep–wake behaviors in infants: An intervention using maternal odor

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     

The effects of noncontingent access to single- versus multiple-stimulus sets on self-injurious behavior

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.     

The Importance of Item Selection in "Knew-It-All-Along" Studies of General Knowledge

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.     

COMPARATIVE STUDIES OF SENSORY RELATEDNESS OF ODOURS

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.     

The Impact of Gender on the Review of the Curricula Vitae of Job Applicants and Tenure Candidates: A National Empirical Study

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.     

The Perceptual Pathway: Tracing the Mechanisms of Political Value Transfer across Generations

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.     

A developmental comparison of the effectiveness of encoding tasks.

In Experiment 1, the free-recall performance of young children, college students, and older adults was examined. Subjects encoded words by simply learning them, by studying them in either base or elaborate sentence frames, or by constructing sentences. Overall recall was better for the college students than for the children or for the older adults, and the college students recalled best in the simple learning condition. The young children recalled best in the sentence construction condition; recall by older adults did not vary as a function of the encoding tasks. In Experiment 2, college students and older adults recalled a categorized list, encoding the words by simply learning them, by studying them in elaborate sentence frames, or by completing word fragments. For both age groups, simple learning produced the highest level of recall. These results suggest that organization provides the most effective encoding system and that older adults may need a more obvious basis for organization than do younger adults. Younger and older adults recalled equally well only when organization was discouraged by conceptual processing.     

Indeterminacy and the principle of need

The principle of need—the idea that resources should be allocated according to need—is often invoked in priority setting in the health care sector. In this article, I argue that a reasonable principle of need must be indeterminate, and examine three different ways that this can be dealt with: appendicizing the principle with further principles, imposing determinacy, or empowering decision makers. I argue that need must be conceptualized as a composite property composed of at least two factors: health shortfall and capacity to benefit. When one examines how the different factors relate to each other, one discovers that this is sometimes indeterminate. I illustrate this indeterminacy in this article by applying the small improvement argument. If the relation between the factors are always determinate, the comparative relation changes by a small adjustment. Yet, if two needs are dissimilar but of seemingly equal magnitude, the comparative relation does not change by a small adjustment of one of the factors. I then outline arguments in favor of each of the three strategies for dealing with indeterminacy, but also point out that all strategies have significant shortcomings. More research is needed concerning how to deal with this indeterminacy, and the most promising path seems to be to scrutinize the position of the principle of need among a plurality of relevant principles for priority setting in the health care sector.
