Auditory Context and Memory Retrieval in Young Infants

Three-month-old infants were trained to move an overhead crib mobile while 1 of 2 musical selections was played. Retention was assessed 1 or 7 days later in the presence of either the same music or a different musical selection. in Experiment 1, the musical selections were very different (classical versus jazz); in Experiment 2, they were much more similar (two classical pieces). Infants in both experiments displayed 1 day retention regardless of wich music was played during the retention test. At 7 days, retention was seen only when the music played during the retention test matched the training music. These data are consistent with similar findings showing that 3-month-old infants'memory is disrupted at long retention intervals when the context present during retention testing does not match the learning context. As the infant's memory wanes, context appears to function as a necessary cue for the retrieval of acquired expectancies.     

Supported playgroups in schools: bonding and bridging family knowledge about transition to formal schooling

Supported Playgroups in Schools (SPinS) are a new initiative in the Australian early childhood education landscape. SPinS are playgroups hosted by a playgroup coordinator co-located on a local school site. Research has identified positive benefits of playgroup participation for children and families. However, little is known about the potential for SPinS to contribute to families’ knowledge about transition to formal schooling. This paper uses the social capital concepts of ‘bonding’ and ‘bridging’ to examine caregivers’ perspectives on their participation in a SPinS with potential to build parental knowledge about their child’s transition to formal schooling. Three main elements of caregivers’ participation in SPinS with such potential are identified, and these elements are mapped into a continuum of low-to-high bonding and bridging relationships to illustrate the potential for SPinS to contribute to the development of increased knowledge about transition to formal schooling by families of young children.     

Examining the Relations of the Home Literacy Environments of Families of Low SES with Children’s Early Literacy Skills

This study examined variability of the home literacy environment (HLE) using multiple measures among families of low SES. The relations of the measures to each other and to children’s early oral language skills and print knowledge were reported. Considerable variability of the self-reported HLE items and the Children’s Title Checklist (CTC) but low correlations were found among items. Children’s expressive language skills were predicted by the CTC. The number of storybooks in the home predicted variance within children’s receptive vocabulary. Concepts about Print (CAP) scores were predicted by the primary caregivers’ frequency of shared reading and the age when parents began reading to children. Children’s letter name scores were not associated with any of the HLE measures in this study. The research provides additional information about the HLE within the homes of low SES using multiple measures and how they relate differentially to children’s early language and literacy skills.     

Scores and foreits — An intuitive model for integer arithmetic

In introducing pupils to directed numbers, the number line is often used as an intuitive model. The C.S.M.S. project, however, recommended that for the teaching of integer subtraction the number line should be abandoned. Here an alternative model is set up and presented to children. Their response over three lessons is described and their learning is assessed in a post-test. Their response and performance is compared to that of a similar group of children learning through a number line model. The two models are compared from practical and theoretical viewpoints.     

Documenting Science Teachers' Pedagogical Content Knowledge Through PaP-eRs

This paper examines science teachers' pedagogical content knowledge and ways in which that knowledge might be captured, articulated and portrayed to others. The research from which this paper is drawn has involved interviews with experienced science teachers in an attempt to make the tacit nature of their practice explicit. Initially, case methodology was envisaged as being a way of documenting these teachers' pedagogical content knowledge. However, over time, the form of knowledge and information that we were gathering and attempting to portray extended beyond that which could reasonably be described as being case-based. Hence we have developed an approach to articulation and portrayal based on what we call the CoRe (Content Representation) – which represents the particular content/topic of the science teaching – and PaP-eRs (Pedagogical and Professional experience Repertoire) – which help to illuminate specific aspects of the CoRe and therefore offer insights into pedagogical content knowledge itself. The results of this study offer new ways of conceptualising what pedagogical content knowledge is and how it might be captured, documented and disseminated.     

Emotional Competence, Emotion Socialization, and Young Children's Peer-Related Social Competence

This study investigated linkages between aspects of emotional competence and preschoolers' social skills with peers. Whether parental emotion socialization practices contributed to the prediction of social skill once emotional competence was statistically controlled was also of interest. Eighty-one predominantly Caucasian preschoolers were videotaped as they participated in three same-sex triadic peer situations. Four peer variables were coded from the videotapes: social initiations, the frequency with which children were the targets of positive social bids, non-constructive anger-related reactions, and prosocial acts. The emotional competence measures included situation knowledge, children's explanations of emotions, positivity of emotional expression during peer play, and emotional intensity. Maternal anger directed at the child was the measure of emotion socialization. Results revealed that the emotional competence variables were meaningfully related to the peer variables and that, for non-constructive anger reactions, maternal reports of anger explained unique variance. Results are discussed in terms of how emotional competence and emotion socialization contribute to peer behavior and the importance of designing and implementing affective intervention programs for young children and their families.     

Prevalence and demographic correlates of childhood maltreatment in an adult community sample

PURPOSE: This study had two aims: (1) to determine the prevalence of five categories of retrospectively reported childhood maltreatment in an adult community sample and (2) to examine relationships between three theoretically and practically chosen demographic variables and childhood maltreatment. METHOD: Participants were a representative sample of 967 adult men and women in the metropolitan Memphis, Tennessee area. They completed a telephone survey that included a reliable, valid questionnaire assessing five types of childhood maltreatment (i.e., emotional abuse, emotional neglect, physical abuse, physical neglect, and sexual abuse) and demographic questions. Simultaneous logistic regression analyses were used to identify demographic correlates of specific trauma types. RESULTS: Prevalence of childhood maltreatment ranged from approximately 30% for women to over 40% for men. Approximately 13% of participants reported multiple forms of maltreatment. The most common forms of trauma for both men and women were physical abuse, physical neglect, and emotional abuse, all of which were highly likely to co-occur. Race, sex, and current educational level were each associated with an increased likelihood of childhood maltreatment; differential relationships with particular maltreatment types were also observed. IMPLICATIONS: These findings highlight the importance of research on the prevalence of and risks for multiple types of childhood maltreatment, particularly in the somewhat neglected area of emotional abuse and neglect. These findings can be used to highlight the need for preventive interventions aimed at the negative sequelae of childhood maltreatment and to tailor preventive interventions to the needs and expectations of those at high risk.

Trace and long-delay fear conditioning in the developing rat

In two experiments with rats, we examined the developmental emergence of conditioned freezing following trace and short-delay conditioning and also included a long-delay comparison group. In the short-delay and trace groups, a 10-sec conditioned stimulus (CS) was paired with shock; for the trace rats, a 10-sec trace interval followed CS termination. The long-delay groups received a 20-sec CS paired with shock, to equate for the longer interstimulus interval (ISI) in the trace group. Trace conditioning emerged later in development than did short-delay conditioning (see Moye & Rudy, 1987). Importantly, long-delay conditioning emerged in parallel with trace conditioning, at a similar time, and with similar strength. These findings suggest a role for the longer ISI, as opposed to the unfilled gap per se, in the late emergence of trace conditioning. The role of the hippocampus in trace conditioning and the possibility that young rats encode the temporal relationship between CSs and unconditioned stimuli are also considered.
