Children's understanding of food and its functions: A preliminary study of the development of concepts of nutrition

Children's developing conceptions of how the body functions nutritionally were examined. Two different tasks provided converging findings. One task asked children to judge the causes of certain end states (e.g., why X is fat). The second task asked children to judge the result of certain contrasting diets (e.g., twin-1 eats twice as much candy as twin-2). The results evidenced; (a) systematic misconceptions on the part of kindergarteners that were overcome by sixth grade; and (b) other fairly sophisticated conceptions present even at the youngest ages tested. The research provides a needed first step toward describing the naive theories of nutrition possessed by children at different ages. Knowledge of childrens' theories of nutrition are essential for optimal planning of curricula and methods in nutrition education.     

Correlates of career progression among Mexican-American college graduates

Individual and structural correlates of career progression were studied among 111 Mexican-American college graduates. Results of the study were that career progression was correlated to (1) high school grades, (2) tolerance for ambiguity, (3) work ethic, (4) psychological success, and (5) need for achievement. Career progression was related to both the extent of career development programs available and the industry in which the employing organization was located.     

Reaction time,evoked brain potentials,and psychometric g in the severely retarded

Measurements derived from reaction time (RT), movement time (MT), and an index of neural adaptability (NA) derived from averaged evoked potentials are significantly related to each other as well as to g factor scores extracted from a battery of 15 psychometric tests in a sample of 54 severely retarded adults. The RT-MT and NA variables show a shrunken multiple R of .64 (p < .001) with psychometric g.     

Free recall by deaf and hearing children: semantic clustering and recall in trained and untrained groups.

Free recall tasks with semantically categorizable stimuli were given to 60 deaf and 60 hearing children, divided equally among Grades 3, 5, and 7 (ages 9, 11, and 13 years, respectively). Half the children were trained to use semantic categorization as a memory aid after the first study-test trial. All subjects were told category labels and sizes on the third recall trial. As hypothesized, older children showed more spontaneous semantic clustering and higher recall scores than younger children. Training increased clustering in all groups, while the provision of category information at retrieval increased clustering regardless of training condition. Contrary to expectations, deaf children used semantic clustering as much as hearing children. Deaf children's recall scores, however, were significantly lower than hearing children's. The specific contrasts observed between deaf and hearing children's performance suggest that deaf children's recall deficiencies probably reflect either inadequate knowledge of category membership or inflexibility in reclassifying individual items, rather than a general inability to recognize and use the categorical nature of a list as a mnemonic aid.     

Selection Procedures in North America

The selection practices of organizations in Canada and the United States are reviewed. These practices are notable insofar as they rarely represent the most valid procedures, nor do they tend to be based on current research knowledge. Some reasons for the current state of selection and assessment procedures include knowledge of appropriate devices, professional competence, and client limitations. The challenge of complying with human rights legislation in North America is viewed by many practitioners as a selection constraint. It is argued, however, that legal requirements support valid selection practices by demanding professional accountability.     

The F word: The experiential construction of flooding in England

In England, flood risk management policy constructs flooding through its physical impacts. Whilst research is starting to reveal the mental health impacts of flooding, it stops short of understanding the experience of being flooded and what this means in terms of understanding the F-word, flooding. Yet for flood communities, the emotional impacts of flooding can prevail for years, if not a lifetime.For people who have been flooded, flooding seeps into every facet of life. It removes the security and safety of home creating instead places of fear, stress, and anxiety. Within this paper we lay bare the emotional impacts of flooding, demonstrating the effect that home unmaking and the cyclical need for home remaking, has on individuals, their quality of life, and revealing the long-term emotional impact of living at risk of flooding.We finish by seeking ways to support communities living at risk of flooding, challenging current flood risk management policy, and identifying how it could be strengthened through understanding these emotional impacts. We propose supporting communities through the emotional turmoil of flooding can help provide hope and restore quality of life to those who live at risk of flooding.     

Preterm newborn pain research review

This narrative review is based on a literature search of PubMed and PsycINFO for research on preterm newborn pain published during the last ten years. The high prevalence of painful procedures being performed with preterm newborns without analgesia (79%), with a median of 75 painful procedures being received during hospitalization and as many as 51 painful procedures per day highlights the importance of this problem. This review covers the pain assessments that have been developed, the short-term effects of the painful procedures, the longer-term developmental outcomes and the pharmacological and alternative therapies that have been researched. The most immediate effects reported for repeated painful procedures include increased heart rate, oxidative stress and cortisol as well as decreased vagal activity. Lower body weight and head circumference have been noted at 32 weeks gestation. Blunted cortisol reactivity to stressors has been reported for three-month-olds and thinner gray matter in 21 of 66 cerebral regions and motor and cognitive developmental delays have been noted as early as eight months. Longer-term outcomes have been reported at school age including less cortical thickness, lower vagal activity, delayed visual– perceptual development, lower IQs and internalizing behavior. Pharmacological interventions and their side effects and non-pharmacological therapies are also reviewed including sucrose, milk and nonnutritive sucking which have been effective but thought to negatively affect breast-feeding. Full-body interventions have included tucking, swaddling, kangaroo care and massage therapy. Although these have been effective for alleviating immediate pain during invasive procedures, research is lacking on the routine use of these therapies for reducing long-term pain effects. Further, additional randomized controlled replication studies are needed.     

The Episodic Nature of Experience: A Dynamical Systems Analysis

Context is an important construct in many domains of cognition, including learning, memory, and emotion. We used dynamical systems methods to demonstrate the episodic nature of experience by showing a natural separation between the scales over which within‐context and between‐context relationships operate. To do this, we represented an individual's emails extending over about 5 years in a high‐dimensional semantic space and computed the dimensionalities of the subspaces occupied by these emails. Personal discourse has a two‐scaled geometry with smaller within‐context dimensionalities than between‐context dimensionalities. Prior studies have shown that reading experience (Doxas, Dennis, & Oliver, 2010) and visual experience (Sreekumar, Dennis, Doxas, Zhuang, & Belkin, 2014) have a similar two‐scaled structure. Furthermore, the recurrence plot of the emails revealed that experience is predictable and hierarchical, supporting the constructs of some influential theories of memory. The results demonstrate that experience is not scale‐free and provide an important target for accounts of how experience shapes cognition.     

Mental rotation with egocentric and object-based transformations

Two experiments were conducted to address methodological issues with past studies investigating the influence of egocentric and object-based transformations on performance and sex differences in mental rotation. In previous work, the egocentric and object-based mental rotation tasks confounded the stimulus type (embodied vs. non-embodied) and transformation task (egocentric vs. object-based). In both experiments presented here, the same stimuli were used regardless of the type of transformation but task instructions were modified to induce either egocentric (left–right judgment) or object-based (same–different judgment) processing. Experiment 1 used pairs of letters whereas Experiment 2 presented pairs of line-drawings of human hands. For both experiments, it was hypothesized that the mental rotation slope for response time would be steeper for object-based than for egocentric transformations. This hypothesis was verified in both experiments. Furthermore, Experiment 2 showed a reduced male advantage for egocentric compared to object-based rotations, whereas this pattern was reversed for Experiment 1. In conclusion, the present study showed that the influence of the type of transformation involved in mental rotation can be examined with the same set of stimuli simply by modifying task instructions.     

Suffering, Sympathy, and (Environmental) Security: Reassessing Rorty’s Contribution to Human Rights Theory

This article reassess Rorty’s contribution to human rights theory. It addresses two key questions: (1) Does Rorty sustain his claim that there are no morally relevant transcultural facts? (2) Does Rorty’s proposed sentimental education offer an adequate response to contemporary human rights challenges? Although both questions are answered in the negative, it is argued here that Rorty’s focus on suffering, sympathy, and security, offer valuable resources to human rights theorists. The article concludes by considering the idea of a dual approach to human rights, combining Rorty’s emphasis on sentiment with an analysis of patterns of responsibility for the underfulfilment of human rights.
