Preschool children's exposure to story grammar elements during parent–child book reading

Twenty‐three preschool‐age children, 3;6 (years; months) to 4;1, were videotaped separately with their mothers and fathers while each mother and father read a different unfamiliar storybook to them. The text from the unfamiliar storybooks was parsed and coded into story grammar elements and all parental extratextual utterances were transcribed and coded for (1) their relationship to the story grammar elements found within the storybook, and (2) the natural strategies parents used to direct their children's attention to these elements. Children's overall exposure to story grammar elements during book reading was also explored for its relationship to their language abilities. Results indicated that parents focused significantly more on the resolution, attempt, and consequence compared to the initiating event and plan, and most frequently used the text and pictures as strategies for recruiting their children's attention to the story grammar elements within the book. In addition, the frequency of parental utterances related to story grammar elements was negatively correlated with children's language abilities. This study did not examine the complexity or depth of parental utterances related to story grammar elements. These findings provide initial evidence that children may derive their understanding of story grammar at least in part through their parents' extratextual discussions during parent–child book reading.     

Fear-potentiated startle using three conditioned stimulus modalities

The capacities of three different conditioned stimulus modalities (light, noise, and airflow produced by a fan) to produce fear-potentiated startle were evaluated. Previous experiments have shown that following either light-shock or noise-shock pairings, both the light and noise conditioned stimuli acquire the ability to potentiate the acoustically elicited startle response in rats (the so-calledfear-potentiated startle effect). In Experiment 1, the ability of airflow produced by a fan to act as a conditioned stimulus was investigated. Rats were given either paired or impaired fan-shock training followed by a test for fear-potentiated startle. The fan conditioned stimulus potentiated startle only in the group given explicit fan-shock pairings. In Experiment 2, we evaluated the discriminability of the three conditioned stimulus modalities. Rats were given light, noise, or fan-shock pairings and were subsequently tested for fear-potentiated startle with the trained conditioned stimulus as well as the two remaining novel conditioned stimuli. Only the trained conditioned stimulus potentiated startle. These results show that fear-potentiated startle can be produced with three discriminable conditioned stimulus modalities, allowing the future use of fear-potentiated startle in the investigation of higher order conditioning phenomena.     

Are academic outcomes of higher education provision relevant to and deliverable in the workplace setting?

Current developments in higher education strongly indicate that the way ahead in many disciplines is much closer co-operation between academia and industry. There is growing demand that recognition should be given to learning, irrespective of the environment in which it occurs.This article reflects on what are deemed to be essential components of a degree, and considers how they might be transformed into forms suitable for demonstration in the work environment. The discussion is supported by findings of a survey carried out in conjunction with a development - Structured Industrial Practice Studies - which integrates academic learning and learning in the work environment for full-time students. The findings, however, are of relevance beyond the particular model of learning and mode of attendance. There appears to be potential for achieving in the workplace aspects of courses which, in recent times, have been the prerogative of higher education establishments. However, such potential is variable between working environments and is dependent on higher education providers adapting to different structures in delivery.

‘Core Subjects’ Policy and Arts Education for the Rich

What happens to art education when the national school curriculum in Israel follows a ‘core subjects’ policy? Allocating only two hours for all five art subjects (visual arts, music, drama, dance and cinematic arts) that remain outside the core curriculum increases the social‐economic gap between children whose parents can fund their art education privately and children whose parents cannot afford this. This also has worrying consequences for art teachers (most of them women) deprived of job security.     

Differences in Shame and Pride as a Function of Children''s Gender and Task Difficulty

3-year-old children were presented with easy and difficult tasks and their emotional responses of shame and pride were observed. No shame was shown when subjects succeeded on the tasks and no pride was shown when they failed. Significantly more shame was shown when subjects failed easy tasks than when they failed difficult tasks, and significantly more pride was shown when subjects succeeded on difficult than on easy tasks. While there were no sex differences in task failures, girls showed more shame than boys. There were no sex differences in pride when subjects succeeded.     

Aversively motivated changes in meal patterns of rats in a closed economy: The effects of shock density

Rats lived continuously in an operant chamber in which they were able to press a bar to obtain food on a chained FR50:CRF schedule that allowed them control of both the size and frequency of individual meals. Independent groups of animals were scheduled to receive 12, 24, 48, or 96 electric shocks per day, which were given randomly in time and independent of the subjects’ behavior. Rats could avoid shock by remaining in a safe area of the chamber, but they were always at risk while barpressing. The introduction of shock resulted in a number of changes in feeding patterns. In rats exposed to a possible 12 shocks/day, meal size increased whereas meal frequency changed very little. At 24 shocks/day, meal frequency decreased whereas meal size increased such that net intake remained stable relative to a preshock baseline period. As shock density was increased to 48 or 96 shocks/day, total intake was suppressed. At 96 shocks/day, both meal frequency and meal size decreased dramatically. Shock-related changes were also observed in rates of operant responding and in the amount of time the animals engaged in feeding-related behavior. All of the animals were able to achieve a greater than 50% reduction in the total number of shocks received relative to equivalent random samples of their position in the apparatus taken during baseline. These results support the position that the nature of defensive changes in feeding behavior that are seen when an aversive stimulus is introduced: into a simulated foraging situation varies as a function of risk.     

Three-Dimensional Display Technologies for Anatomical Education: A Literature Review

Anatomy is a foundational component of biological sciences and medical education and is important for a variety of clinical tasks. To augment current curriculum and improve students’ spatial knowledge of anatomy, many educators, anatomists, and researchers use three-dimensional (3D) visualization technologies. This article reviews 3D display technologies and their associated assessments for anatomical education. In the first segment, the review covers the general function of displays employing 3D techniques. The second segment of the review highlights the use and assessment of 3D technology in anatomical education, focusing on factors such as knowledge gains, student perceptions, and cognitive load. The review found 32 articles on the use of 3D displays in anatomical education and another 38 articles on the assessment of 3D displays. The review shows that the majority (74 %) of studies indicate that the use of 3D is beneficial for many tasks in anatomical education, and that student perceptions are positive toward the technology.
