Why Koreans Are More Likely to Favor “Apology,” While Americans Are More Likely to Favor “Thank You”

Two studies investigated whether apologies or thanks are preferred in asking favors in the United States and Korea, and how this relates to perceptions of reduction in positive and negative face threats. In the first study (n = 224), participants composed an e‐mail message where a favor was asked. In the second (n = 807), participants completed questionnaires including a prototypical e‐mail for the situation described in Study 1, as well as measures of negative and positive face threats. Findings showed that (a) Koreans more frequently included apologies in favor‐asking messages, while Americans more frequently included thanks; and (b) Americans considered repeated thanks to reduce the threat to hearers' negative and positive face, but Koreans considered repeated apologies to reduce the threat to speakers' positive face.     

Auditing the quality of care of a crisis center

The purpose of this paper is twofold: First, it defines and describes different types of audits and areas of patient care which lend themselves to a quality of performance review. Second, it describes an audit application at a hospital-based crisis intervention center and the corrective action taken on the basis of the findings. The major emphasis of the audit was to determine the quality of medical-psychiatric consultation and to develop criteria for its initiation.

Oculographic assessment of workload influence on flight performance

Presented are specific parameters of visual information intake in pilots on the job. The role of eye movements in the process of visual stimulus reception is discussed. Our own study on a MIG-23 flight simulator is presented. The method of oculographic testing of pilots performing professional assignments differing in workload is presented, and the practical implications of oculographic research are discussed.     

Teaching the Bible in the Context of General Education

Three conceptions of general education developed under the titles ‘general,’‘generalist,’ and ‘generalizing’ are matched with appropriate strategies for teaching the Bible. These provide the basis for two points relevant to teaching the Bible in colleges and universities: first, that the prime object of attention is not the Bible, but rather a corporate agreement regarding an educational project; and second, that the ways in which the Bible might be taught will vary, appropriately, according to the ways in which that educational enterprise is understood. A corollary is stated: teachers of the Bible need to be as informed about research in teaching as they are in biblical research.     

A Search for the Optimal Stimulus

How do stimulus size and item number relate to the magnitude and direction of error on center estimation and line cancellation tests? How might this relationship inform theories concerning spatial neglect? These questions were addressed by testing twenty patients with right hemisphere lesions, eleven with left hemisphere lesions and eleven normal control subjects on multiple versions of center estimation and line cancellation tests. Patients who made large errors on these tests also demonstrated an optimal or pivotal stimulus value, i.e., a particular size center estimation test or number of lines on cancellation that either minimized error magnitude relative to other size stimuli (optimal) or marked the boundary between normal and abnormal performance (pivotal). Patients with right hemisphere lesions made increasingly greater errors on the center estimation test as stimuli were both larger and smaller than the optimal value, whereas those with left hemisphere lesions made greater errors as stimuli were smaller than a pivotal value. In normal subjects, the direction of errors on center estimation stimuli shifted from the right of true center to the left as stimuli decreased in size (i.e., the crossover effect). Right hemisphere lesions exaggerated this effect, whereas left hemisphere lesions diminished and possibly reversed the direction of crossover. Error direction did not change as a function of stimulus value on cancellation tests. The demonstration of optimal and pivotal stimulus values indicates that performances on center estimation and cancellation tests in neglect are only relative to the stimuli used. In light of other studies, our findings indicate that patients with spatial neglect grossly overestimate the size of small stimuli and underestimate the size of large stimuli, that crossover represents an “apparent” shift in error direction that actually results from normally occurring errors in size perception, and that the left hemisphere is specialized for one aspect of size estimation, whereas the right performs dual roles.     

Aspects of biochemical differentiation in the central nervous system

A demonstration of cell-specific patterns of development in the immature CNS is provided by examples of characteristic, cellspecific time-courses of enzyme development in different classes of brain cells isolated in highly purified form by bulk-separation from the cerebral and cerebellar cortex of the growing rat. The enzymatic analysis was carried out at the level of the nerve and glial cell lysosomes and mitochondria, two subcellular organelles crucial to the economy of all cells. The findings reveal rather similar developmental patterns for the lysosomal hydrolase N-acetyl-β-D-glucosaminidase in neurons and glial cells of the cerebral cortex as well as in two different cerebellar nerve cell types, the Purkinje and the granule cell. However, significant differences in the post-natal chronology of development of the mitochondrial enzyme α-glycerophosphate dehydrogenase were noted between cortical nerve and glial cells, the glial enzyme exhibiting 6-fold higher levels of activity than the neuronal one throughout the first month of postnatal life. The findings emphasize the feasibility as well as the necessity of studies aimed at the elucidation of the cell-specific aspects of the biochemistry of developing nerve and glial cells.     

Adaptation effects on evoked electrical taste

In spite of a clear increment in absolute thresholds as an effect of self-adaptation, the electrically provoked taste sensation does not show a reduction in subjective intensity during the protracted stimulation time. Chemical cross-adaptation effects on the threshold and suprathreshold levels of electrical taste are observed only when the adapting solutions are electrolytes regardless of their taste qualities. It seems that the stability of perceived intensity during current flow is principally due to some irritation of the sensitive tissue of the tongue, whereas cross-adaptation effects may be attributed to the potential changes across the excitable membranes caused by electrical properties of adapting electrolytic solutions.     

Pop-out and pop-in: Visual working memory advantages for unique items

Attentional control is thought to play a critical role in determining the amount of information that can be stored and retrieved from visual working memory (VWM). We tested whether and how task-irrelevant feature-based salience, known to affect the control of visual attention, affects VWM performance. Our results show that features of a task-irrelevant color singleton are more likely to be recalled from VWM than non-singleton items and that this increased memorability comes at a cost to the other items in the display. Furthermore, the singleton effect in VWM was negatively correlated with an individual’s baseline VWM capacity. Taken together, these results suggest that individual differences in VWM storage capacity may be partially attributable to the ability to ignore differences in task-irrelevant physical salience.
