"Reality" birth: marketing fear to childbearing women

In this column, the authors examine the effect of "reality" television shows on expectant parents' fears of childbirth.     

Questions from our readers: commentary on "lamaze in the 21st century"

In response to Lamaze International's latest position paper, "Lamaze in the 21st Century," the author discusses the concept of normal birth and identifies the need for an advocacy effort in support of normal birth as the standard procedure.     

A web-based breastfeeding education program

Two Web-based breastfeeding programs were developed to provide new parents with necessary information on proper breastfeeding techniques. One version was plain text and the other version combined text with graphics. The computer was viewed as a valuable learning tool. The breastfeeding program that contained graphics was preferred over the text-only program. Educators are encouraged to use Web-based graphic programs to provide breastfeeding education to new parents.     

Teachers' ratings of functional communication in students with cochlear implants

The study examined factors associated with teachers' ratings of functional communication skills of students with cochlear implants. Deaf students living in and around a metropolitan area were surveyed to locate 51 with cochlear implants. Teachers rated each student's functional use of the implant, given three defined ratings. Additional information regarding sex, communication option, placement, home language, rural or nonrural address, etiology, and presence or absence of an additional disability was gathered. Chi-square analyses of the data were performed. The data indicated that students with a known etiology and a rural address, and who used sign language at home or school, were less likely than others to use the implant as a primary channel for receptive communication. The authors suggest that the teacher's role in implant use warrants more attention. Speech-language pathologists, otologists, audiologists, and parents of deaf children should consider all factors related to successful implant use before advocating or choosing this financially, emotionally, and therapeutically challenging option.     

Infants parse dynamic action

As observers of human behavior, infants are faced with a complex flow of motion in which pauses are rare and only occasionally coincide with boundaries between intentional actions. Two studies investigated whether, despite such complexity, 10- to 11-month-old infants (N = 16 for each study) possess skills for parsing ongoing behavior along boundaries correlated with the initiation and completion of intentions. After being familiarized with digitized sequences of continuous everyday action, infants showed renewed interest in test versions in which motion paused in the midst of an actor's pursuit of intentions (interrupting test videos). In contrast, pauses that suspended motion at intention boundary points (completing test videos) sparked no such renewed interest on infants' part. Moreover, basic salience differences between the two types of test videos were not the source of infants' increased interest when intentions were interrupted (Study 2). These findings demonstrate that infants readily detect disruptions of the structure inherent in intentional action, and hence parse ongoing behavior with respect to such structure. Such parsing skill is likely a prerequisite to the development of genuine intentional understanding.     

Construction of meaning in the authentic science writing of deaf students

This study examines how students construct meaning through writing during authentic science activities. To determine how well students understood science concepts, we analyzed 228 writing samples from deaf students in grades 6 through 11 as well as the explanatory and reflective comments of their teachers. The analyses indicate that certain process writing strategies were differentially useful in helping deaf students to construct meaning and in allowing teachers to evaluate the constructed meaning. Three instructional conditions and two teacher variables were found to play roles in determining the accuracy and adequacy of the writing: (1) the writing prompts the teachers used, (2) the focus for the writing, (3) follow-up to the initial writing activity, (4) the teacher's content knowledge, and (5) the teacher's ability to interpret student writing. The authors recommend future applications of writing-to-learn strategies and suggest directions for further research and changes in teacher education.     

The use of limericks to engage student interest and promote active learning in an undergraduate course in functional anatomy

The study of anatomy is a content-dense discipline with a challenging vocabulary. A mnemonic is a series of letters, a word, a phrase, or a rhyme that students can use when studying to facilitate recall. This project was designed to promote active learning in undergraduate students studying anatomy and physiology by asking them to create limericks based on course content and then to evaluate the limericks written by their peers for learning value, accuracy, style, and adherence to limerick characteristics. Students (278 and 288, respectively, in the 2009 and 2010 sections of ANP1107) worked in groups of three to create a total of 242 limericks. Peer evaluation was accomplished in two stages using a 20-point marking rubric. In Stage 1, students were randomly divided into 10 groups (n = 23 ± 2 students) with each group member evaluating the same 12 ± 1 limericks. In Stage 2, the top 19% of limericks were reevaluated by all students so that the best three could be chosen. In each of the two years, 60% of students completed all parts of the assignment. Higher percentages (75-80%) participated in limerick writing and one of the two assessment stages. A positive association was noted between level of student participation in the limerick assignment and final course marks. Limerick creation and evaluation can be used to promote active learning by encouraging students to review functional-anatomy-based content to create limericks with good learning value and to provide valid assessments of limericks written by their peers.     

The role of motor experience in understanding action function: the case of the precision grasp

Recent evidence suggests adults and infants selectively attend to features of action, such as how a hand contacts an object. The current research investigated whether this bias stems from infants' processing of the functional consequences of grasps: understanding that different grasps afford different future actions. A habituation paradigm assessed 10-month-old infants' (N = 62) understanding of the functional consequences of precision and whole-hand grasps in others' actions, and infants' own precision grasping abilities were also assessed. The results indicate infants understood the functional consequences of another's grasp only if they could perform precision grasps themselves. These results highlight a previously unknown aspect of early action understanding, and deepen our understanding of the relation between motor experience and cognition.     

The nominal passover effect depends on addressee age, speaker goal, and object similarity

If after teaching a label for 1 object, a speaker does not name a nearby object, 3-year-olds tend to reject the label for the nearby object (W.E. Merriman, J.M. Marazita, L.H. Jarvis, J.A. Evey-Burkey, and M. Biggins, 1995a). In Studies 1 (5-year-olds) and 3 (3-year-olds), this effect depended on object similarity. In Study 2, when a speaker used a label without teaching it, 5-year-olds showed no passover effect. 3-year-olds showed none for inanimate objects, but one for animate objects. When extraneous factors that may have promoted animate object individuation were eliminated (Study 3), 3-year-olds showed the effect when a label was taught, but not when it was merely used. Children honor rational restrictions on when the unacceptability of a name can be inferred from its nonoccurrence.
