Adaptation to displacing prisms in human infants.

This research reports a first attempt to study adaptation to laterally displacing prisms in human infants of ages six to ten months. Twenty infants were tested over four days under conditions similar to those used in adult adaptation studies. Evidence was found of vigorous adaptation when infants were exposed to base-right prisms under conditions of active exposure. Detailed consideration is given to the conditions and methods of studying adaptation in infants and implications for adult studies.     

Patterns of movement in the first 6 months of life: new directions

The field of infant perceptual development has relied heavily on the preferential-looking and habituation paradigms. Despite the obvious advantages of employing standardized methodologies, there is a need to study how perceptual variables give rise to and guide action beginning in the neonatal period. It is argued here that, in the first 5 months of life, it is important to distinguish reflexive patterns of movement from voluntary and cortically controlled patterns. Some criteria are defined. This paper describes three experiments which utilized movement counters to record developmental changes in the frequency and synchrony of limb movements in infants under 5 months. The results show that there is a general increase in frequency of limb movements from 1 to 5 months, but with a plateau or even a decrease in activity from the middle of the third month to the end of the fourth month. It was also demonstrated that synchrony scores (co-activation) for pairs of limbs showed significant increases from 1 month to 5 months. Finally, in all three experiments the presentation of an attractive toy resulted in suppression of activity. The results of the three experiments are interpreted to measure a gradual increase in cortically controlled movement patterns.     

A method for the preparation of audio tapes for dichotic listening research

A simple method for producing audio tapes with temporally synchronized messages is described. The duration and spacing of words can be precisely controlled. This method requires a minimum of elaborate equipment, yet synchronization is very accurate with highly intelligible speech.     

The Instructional Characteristics of Inclusive Classes for Elementary Students with Severe Disabilities: An Exploratory Study

This exploratory study examined several instructional characteristics of elementary classrooms serving students with severe disabilities including the individuals who provided instruction to students, the instructional behaviors of these teachers, and grouping structures. The analysis focused on the impact of these variables on the academic responding of students and the extent to which they were the exclusive target of instruction by the various teachers. Observation data were collected on six students with severe disabilities participating in general elementary classrooms for reading or math, and at least one other subject area. The academic responding of students was similar across general education teachers, special education teachers, paraprofessionals, and peers; and the instructional behaviors of each of these groups of instructors was similar. Students had higher rates of academic responding during one-on-one and small group instruction, but they also were engaged in instructional tasks during whole class instruction. Finally, academic responding was positively associated with instruction focused on the student, one-on-one instruction, and instructional interactions with teachers. Academic responding was negatively correlated with whole class instruction and instructional behaviors that were not directed at the student.     

Still Fighting the “War for Talent”? Bridging the Science Versus Practice Gap

The purpose of this article is to identify some the most critical outstanding issues faced by practitioners in undertaking effective talent management. In spite of the global financial crisis, talent management will continue being one of the most important challenges faced by organizations in the coming decade. Workforce demographics and skills shortages are likely to make the “war for talent” fiercer than ever before making effective talent management a competitive necessity. While talent management is rapidly developing as a research field, there are many areas and questions that need to be explored. These questions are likely to have a particularly important applied benefit as they represent some of the key challenges organizations are grappling with in effectively managing their talent. The article asks researchers in the field to consider the questions proposed in developing future research agendas.     

When accurate and inaccurate eyewitnesses look the same: a limitation of the ‘pop‐out’ effect and the 10‐ to 12‐second rule

Research has found support for a ‘pop‐out effect’ that occurs when witnesses who accurately identify a criminal from a lineup are faster and uses more automatic processing than inaccurate witnesses who misidentify a foil. We present evidence that this finding may not occur with biased lineups. Witnesses to a mock theft were asked to make a lineup identification and three types of witnesses were compared: (1) accurate witnesses who identified a thief, (2) inaccurate witnesses who misidentified a foil who was more similar looking to the thief than the other lineup foils and (3) inaccurate witnesses who misidentified a foil who was not more similar in appearance to the thief than the other lineup foils. Accurate witnesses who identified the thief and inaccurate witnesses who misidentified a foil more similar to the thief than the other lineup foils were indistinguishable; both were faster, used more automatic recognition processes and were more confident than inaccurate witnesses who identified other foils.

Prescriptive Analysis: Further Individualization of Hypothesis Testing in Brief Experimental Analysis of Reading Fluency

Brief experimental analyses (BEA) have been used to identify effective individualized interventions for improving reading fluency with school-age children. Interventions involving incentives, modeling, repeated reading, and error correction are most often tested in a BEA. However, these interventions are rarely modified according to individual student needs. The current study examined the effects of varied levels of modeling (passage, sentence, word) and varied contingencies (tracking and fluency) on fluency in non-treated high-word overlap passages and general outcome measure passages. BEA-identified interventions were effective for improving reading fluency on non-treated passages for both second grade students and the third grade student. Notably, the effects reversed when intervention was withdrawn with one of the second grade students. Results are discussed in terms of considerations in the application of BEA technology in the schools.     

Anorexia nervosa: the treatment of a male case with combined behavioural and family therapy

The successful treatment of a case of anorexia nervosa in a 14-year-old boy is described in this paper. The treatment comprised an initial month-long hospital-based behavioural weight gain programme. Concurrently a family evaluation was conducted. Family therapy, involving the parents only, was conducted over a subsequent four month period. The management of a relapse four months after the termination of treatment is described and information obtained at 9 and 16 month follow up is presented.
