Abstract “Food for Thought” provides an opportunity for review of pertinent topics to add to updates in areas of concern for professionals involved with feeding and swallowing issues in infants and children. Given the frequency with which speech-language pathologists (SLPs) make decisions to alter feedings when young infants demonstrate silent aspiration on videofluoroscopic swallow studies (VFSS), the need for increased understanding about cough and its development/maturation is a high priority. In addition, understanding of the role(s) of laryngeal chemoreflexes (LCRs), relationships (or lack of relationships) between cough and esophagitis, gastroesophageal reflux (GER), and chronic salivary aspiration is critical. Decision making regarding management must take into account multiple systems and their interactions in order to provide safe feeding for all children to meet nutrition and hydration needs without being at risk for pulmonary problems. The responsibility is huge and should encourage all to search the literature so that clinical practice is as evidence-based as possible; this often requires adequate understanding of developmentally appropriate neurophysiology and function.

Effects of four retest-practice sessions separated by 2 h intervals on the relationship between general intelligence and four reaction time tasks (two memory tests: Sternberg's memory scanning, Posner's letter comparison; and two attention tests: continuous attention, attention switching) were examined in a sample of 83 male participants. Reaction times on all tasks were shortened significantly. The effects were most pronounced with respect to the Posner paradigm and smallest with respect to the Sternberg paradigm. The relationship to general intelligence changed after practice for two reaction time tasks. It increased to significance for continuous attention and decreased for the Posner paradigm. These results indicate that the relationship between psychometric intelligence and elementary cognitive tasks depends on the ability of skill acquisition. In the search for the cognitive roots of intelligence the concept of learning seems to be of importance.

Abstract. Fighter pilots may be exposed to extended flight missions. Consequently, there is increasing concern about fatigue. We investigated the effects of fatigue and cognitive performance in a simulated 11-hr mission in the 39 Gripen fighter aircraft. Five cognitive tasks were used to assess cognitive performance. Fatigue was measured with the Samn–Perelli Fatigue Index. Results showed that performance in the non-executive task degraded after approximately 7 hr. Fatigue ratings showed a matching trend to the performance in this task. Performance in tasks taxing executive functions did not decline. We interpreted that fatigue can be overridden by increased attentional effort for executive tasks but not for non-executive components of cognition. Participants underestimated their performance and metacognitive accuracy was not influenced by fatigue.
