Assessing Speech Discrimination in Individual Infants

Assessing speech discrimination skills in individual infants from clinical populations (e.g., infants with hearing impairment) has important diagnostic value. However, most infant speech discrimination paradigms have been designed to test group effects rather than individual differences. Other procedures suffer from high attrition rates. In this study, we developed 4 variants of the Visual Habituation Procedure (VHP) and assessed their robustness in detecting individual 9‐month‐old infants' ability to discriminate highly contrastive nonwords. In each variant, infants were first habituated to audiovisual repetitions of a nonword (seepug) before entering the test phase. The test phase in Experiment 1 (extended variant) consisted of 7 old trials (seepug) and 7 novel trials (boodup) in alternating order. In Experiment 2, we tested 3 novel variants that incorporated methodological features of other behavioral paradigms. For the oddity variant, only 4 novel trials and 10 old trials were used. The stimulus alternation variant was identical to the extended variant except that novel trials were replaced with “alternating” trials—trials that contained repetitions of both the old and novel nonwords. The hybrid variant incorporated elements from both the oddity and the stimulus alternation variants. The hybrid variant proved to be the most successful in detecting statistically significant discrimination in individual infants (8 out of 10), suggesting that both the oddity and the stimulus alternation features contribute to providing a robust methodology for assessing discrimination in individual infants. In Experiment 3, we found that the hybrid variant had good test‐retest reliability. Implications of these results for future infant speech perception work with clinical populations are discussed.     

The derivation of a brief Student Nurse Stress Index

The lack of an adequate measure of perceived sources of stress for student nurses led to the construction of the Student Nurse Stress Index (SNSI). Responses from 235 first-year student nurses to 35 items from the Beck and Srivastava Stress Inventory (Beck, and Srivastava, 1991), and 15 new items, were subjected to exploratory factor analysis using principal components analysis and oblimin rotation. A reliable 22-variable solution with a simple oblique structure including Academic load, Clinical sources, Interface worries, and Personal problems factors was obtained in this initial sample, and confirmed at an exploratory level in a further independent validation sample of 188 first-year students. Confirmatory factor analysis established the four-factor model in the first sample, but required that three variables load onto more than one factor. This more complex four-factor model was confirmed using independent data from the validation sample, and the total invariance of factor loadings and factor covariances of this more complex four-factor model was established in both data sets simultaneously using multi-sample techniques. The SNSI shows cross-sample factor congruence, good internal reliabilities, and concurrent and discriminant validity across a range of reporting conditions.     

"FRANCE NEEDS CHILDREN":

This article examines debates and discussions surrounding French pronatalist policies enacted in the 1980s. Drawing on data collected from a wide range of primary and secondary sources, including daily newspapers, parliamentary debates, and French feminist publications, I explore the following questions: First, does pronatalism spring from conservative nationalist ideologies that conflict with feminist projects? Second, how have French feminists reacted to the pronatalist agenda? Finally, could women's equity serve as an impetus for instituting policies that would encourage births? My analysis suggests that nationalism in France takes many forms, and a wide spectrum of political actors from both the political left and right have supported pronatalist initiatives in the name of “the nation.”     

Resignation or Dismissal?: When a CEO and a President Clash

In the executive director's opinion, Bluehills Family Services' board of directors had serious problems with their organizational governance. These difficulties came to a head in an apparently unresolvable clash between the executive director and the board president. Given the preexisting board and organization perceptions, could an emergency board meeting produce a positive outcome, and would the executive director's participation be counterproductive?     

Postcommunist Societies in Times of Transition: Perceptions of Change Among Adolescents in Central and Eastern Europe

This article examines adolescents' perceptions of the economic changes and the justice of the new "social contract" in Eastern/Central Europe. Focusing on three countries, Hungary, Bulgaria, and the Czech Republic, it explores the social, political, and economic environments in which adolescents came of age in 1990. Surveys conducted among high school students in each country during 1995 tapped their perceptions of the economy, the local community, and their personal beliefs about the efficacy of individual initiative and hard work. Responses differed significantly based on age, gender, social class, value orientation, and country. Older adolescents and girls were more likely to observe that economic disparities were growing in their country and to be cynical about the value of hard work. Those with socialist values also discounted the value of recent changes. Adolescents in the Czech Republic were the least cynical about economic changes, whereas those in Bulgaria were the most cynical, with Hungarian youth the least optimistic about the future.     

Behavior of Mothers and Infants With and Without Down Syndrome During the Still‐Face Procedure

There has been limited study of how the constitutional characteristics of infants with Down syndrome (DS) influence the patterning of their relations with caregivers. To assess natural and perturbed interactions between infants with DS and their mothers, we tested ten 6‐month‐old infants with DS and 20 typically developing (TD) 4‐month‐old of similar mental age. Participants were videotaped with their mothers in a natural face‐to‐face interaction, a brief period when the mothers adopted a still‐face, and a subsequent reengagement phase. There was little to distinguish the infants in the initial phase of natural interaction, but the mothers of infants with DS were more likely to show assertive warmth, and unlike in the case of mothers of TD infants, high maternal directiveness tended to be associated with lower levels of infant looking and lack of fussing. During the still‐face episode, infants of both groups showed reduced looking and smiling, although infants with DS tended to show lower levels of fussing and fewer in this group showed fussing in the reengagement phase. Therefore DS infants were somewhat similar to TD infants of comparable mental age in being responsive to the still‐face procedure, but showed indications of group differences in intense emotional reactivity.     

Development of Pre-Word-Learning Skills in Infants with Cochlear Implants

Families of infants who are congenitally deaf now have the option of cochlear implantation at a very young age. In order to assess the effectiveness of early cochlear implantation, however, new behavioral procedures are needed to measure speech perception and language skills during infancy. One important component of language development is word learning-a complex skill that involves learning arbitrary relations between words and their referents. A precursor to word learning is the ability to perceive and encode intersensory relations between co-occurring auditory and visual events. Recent studies in infants with normal hearing have shown that intersensory redundancies, such as temporal synchrony, can facilitate the ability to learn arbitrary pairings between speech sounds and objects (Gogate & Bahrick, 1998). To investigate the early stages of learning arbitrary pairings of sounds and objects after cochlear implantation, we used the Preferential Looking Paradigm (PLP) to assess infants' ability to associate speech sounds to objects that moved in temporal synchrony with the onset and offsets of the signals. Children with normal hearing ranging in age from 6, 9, 18, and 30 months served as controls and demonstrated the ability to learn arbitrary pairings between temporally synchronous speech sounds and dynamic visual events. Infants who received their cochlear implants (CIs) at earlier ages (7-15 months of age) performed similarly to the infants with normal hearing after about 2-6 months of CI experience. In contrast, infants who received their implants at later ages (16-25 months of age) did not demonstrate learning of the associations within the context of this experiment. Possible implications of these findings are discussed.     

Love and money: payment, motivation and the fostering task

Although the payment of foster carers has attracted greater attention in recent writing and research, coverage of the issues has been limited. In this study, based on interviews with 20 female carers, the place of payment within foster care is explored in greater depth. The focus is on charting how carers perceive their task as ‘parenting’ or ‘job’, whether and how they experience payment as compensation or as an appropriate reward for their skills. Also examined are the ways in which payment may impact upon the practice of foster care, for example in decision making over the taking or ending of placements and the provision of aftercare support for care leavers. The study highlights the distinctive nature of foster care as an institution that straddles the public and private domains, and examines the resulting complexities. It concludes by suggesting that while payment issues provide important threads that run throughout foster care, their influence is ultimately limited by the latter's base within the family.
