Mothers' Physiological and Affective Responding to Infant Distress: Unique Antecedents of Avoidant and Resistant Attachments

In a sample of 127 mother–infant dyads, this study examined the predictive significance of mothers' physiological and observed emotional responding within distressing and nondistressing caregiving contexts at 6 months for infant attachment assessed with Fraley and Spieker's (2003) dimensional approach and the categorical approach at 12 months. Findings revealed that a lesser degree of maternal respiratory sinus arrhythmia withdrawal and higher levels of maternal neutral (vs. positive) affect within distressing (vs. nondistressing) caregiving contexts were distinctive antecedents of avoidance versus resistance assessed dimensionally (but not categorically), independent of maternal sensitivity. Discussion focuses on the usefulness of examining mothers' physiological and affective responding, considering the caregiving context, and employing the dimensional approach to attachment in identifying unique antecedents of patterns of attachment insecurity.     

Comparison of individual and group-based load-velocity profiling as a means to dictate training load over a 6-week strength and power intervention

ABSTRACT

This study compared the effects of dictating load using individual (ILVP) or group (GLVP) load-velocity profiles on lower-body strength and power. Nineteen trained males (23.6 ± 3.7 years) completed a back squat one-repetition maximum (1-RM), load-velocity profiling (LVP), and countermovement (CMJ), static-squat (SSJ) and standing-broad (SBJ) jump tests before and after 6 weeks of resistance training. Participants were randomly assigned to an ILVP, or GLVP intervention with intra-session load dictated through real-time velocity monitoring and prediction of current relative performance using either the participant’s LVP (ILVP) or a LVP based on all participant data (GLVP). Training resulted in significant increases in back squat 1-RM for the ILVP and GLVP group (p < 0.01; 9.7% and 7.2%, respectively), with no group-by-time interaction identified between training groups (p = 0.06). All jump performance significantly increased for the ILVP group (p < 0.01; CMJ: 6.6%; SSJ: 4.6%; SBJ: 6.7%), with only CMJ and SSJ improving for the GLVP group (p < 0.05; 4.3%). Despite no significant group-by-time interaction across all variables, the ILVP intervention induced a greater magnitude of adaptation when compared to a GLVP approach. Additionally, an individualised approach may lead to greater positive transfer to power-based movements, specifically vertical and horizontal jumps.     

Making Meaningful Choices: an investigation into young children's intonation patterns in storytelling

Abstract This paper investigates the meaningful choices in intonation made by young children. A category system for classifying choices is outlined and an experiment is reported in which randomly selected groups of 41/2‐5 year‐olds heard and retold stories in different situations. Results indicate that all groups distinguished narrative from other forms of discourse and drew upon intonation resources appropriately. Differences were found between recalling a story with pictures and one without, suggesting that these are different cognitive tasks and that children make different selections from choices available to them.     

The electronic campus: The collaboratory: A new model for teaching and learning in the electronic environment

The “collaboratory librarian” in the Bartle Library at Binghamton University describes an innovative use of electronic networks to support traditional teaching and learning. However, the collaboratory concept also offers all educators exciting opportunities to promote learning in both the extracurricular and cocurricular dimensions of campus life.     

A Systematic Approach to Teaching Reading and Spelling to a Nine‐year‐old Boy with Severely Impaired Literacy Skills

Abstract An attempt was made to develop reading and spelling skills in a nine year‐old boy who was a severe underachiever in both areas, over an 18 month treatment period. A structured and systematic approach was used with provision of incentives via token reinforcement which could be exchanged for back‐up reinforcers of the child's choice. The remedial reading programme was successful in developing systematic reading strategies which were applied to the decoding of new words. These gains generalised outside the tutoring situation and were reflected in performance on a standardised test of reading. The spelling programme was less successful although the goal of lessening the disparity between spelling age and chronological age was achieved. Follow‐up at 14 months indicated continued gains although the rate of progress was considerably slower following the cessation of regular remedial teaching particularly in the area of spelling. Implications for the development of future remedial programmes are discussed.
