Cultural psychological processes underlying workplace remuneration in Japanese and European American contexts

Japan's remuneration systems are moving away from seniority-based pay towards individual performance-based pay. We tested how the latter system works within the Japanese cultural context and whether the operation and functioning of the system reflects general psychological tendencies found in Japan. Japanese (Study 1 n = 197; Study 2 n = 235) and European American (Study 1 n = 201; Study 2 n = 186) participants read vignettes that described workplace success centred on a focal employee and including a team. Participants attributed contribution and rewards (financial and status) to a range of agents and factors with graded levels of focus, from the focal employee having the greatest and luck having the least. In general, we found that Japanese participants attributed greater contribution and reward to less focal agents and factors while European American participants attributed greater contribution and reward to more focal agents, in addition to some specific differences between the tasks and reward types. We discuss implications for more nuanced theorizing of the interaction between institutional systems and psychological processes.     

Japan's dilemma with the definition of death

Japan is unusual among industrialized countries in its reluctance to use brain criteria to determine death and harvest transplant organs. This results from public distrust of the medical profession due to an earlier incident, and from concern that technological interventions will threaten religious and cultural traditions surrounding death and dying. Public acceptance is growing, however, as medical professional groups and universities develop brain criteria, and as pressure from patients who could benefit from a transplant, as well as from foreign countries, increases.     

Impairment of nonverbal oral movements in aphasia

Thirty-six patients with unilateral cerebral vascular damage were required to perform a number of oral motor tasks, both verbal and nonverbal. Nonfluent aphasics were impaired in the imitation of single oral movements, as previously reported. However, on the imitation of complex nonverbal oral movements fluent aphasics were impaired as well as nonfluents. This impairment was not explicable on the basis of visual memory or perceptual deficits, nor on the basis of sensory thresholds as measured on the tongue. The findings suggest that deficits in coordinating oral movements are fundamental to most aphasic impairments, the meaningfulness of the responses not being a critical factor in the appearance of the defect.     

Sex differences in recall of real or nonsense words

Women perform better than men on tests of verbal memory, but the nature of this advantage has not been precisely established. To examine whether phonemic memory is a factor in the female advantage, we presented, along with other verbal memory tasks, one containing nonsense words. Overall, there was the expected female advantage. However, an examination of the individual tests showed female superiority in recall of the real words but not the nonsense words.     

Investigating the acute effect of an aerobic dance exercise program on neuro-cognitive function in the elderly

ObjectiveThe present study investigated the types of aerobic dance programs that positively impact cognition, such as executive function, in elderly people.DesignRandomized controlled trial.MethodThe study compared the effects of acute aerobic dance exercise on cognitive performance using two 40-min aerobic dance programs. Thirty-four elderly participants, aged 65–75 years, were randomly assigned into either free (N = 17) or combination (N = 17) style workout groups. The free style (FR) workout consisted of several patterns of movement, while the combination style (CB) workout consisted of similar patterns of movement to FR, but the patterns were joined to form a long choreographic routine. Both dance programs were controlled to be the same in exercise intensity, approximately 40% heart rate reserve. Reaction time and correct rates were measured using a task-switching reaction time test to evaluate executive cognitive performance immediately before and after the 40-min dance exercise.ResultsA two-way (dance program × pre-post dance exercise) repeated-measures analysis of variance for switch reaction time increase (switch cost) demonstrated a significant interaction (p = .006), showing that the switch cost in the CB group became smaller after the dance exercise than before (p = .009).ConclusionThe results suggest that the executive cognitive network was facilitated in a CB dance workout that has a dual-task nature and induces movement (task) interference with unexpected movement changes.     

An investigation of surface reconstruction from binocular disparity based on standard regularization theory: comparison between "membrane" and "thin-plate" potential energy models

Visible surfaces of three-dimensional objects are reconstructed from two-dimensional retinal images in the early stages of human visual processing. In the computational model of surface reconstruction based on the standard regularization theory, an energy function is minimized. Two types of model have been proposed, called "membrane" and "thin-plate" after their function formulas, in which the first or the second derivative of depth information is used. In this study, the threshold of surface reconstruction from binocular disparity was investigated using a sparse random dot stereogram, and the predictive accuracy of these models was evaluated. It was found that the thin-plate model reconstructed surfaces more accurately than the membrane model and showed good agreement with experimental results. The likelihood that these models imitate human processing of visual information is discussed in terms of the size of receptive fields in the visual pathways of the human cortex.     

The Role of Reflective Functioning in Predicting Marital and Coparenting Quality

Reflective functioning (RF) is a measure of mentalization—the capacity to think about one’s own and others’ thoughts and feelings and to understand the connections between mental states and behaviors. Previous research indicates a decline in marital quality across the transition to parenthood, and some studies have found that parents are less happy than non-parents. Thus, researchers have called for research into possible moderators of these patterns. RF may help couples navigate this transition by more easily taking each other’s (and the infant’s) perspective and understanding each other’s behaviors. Much of the research on RF has focused on mothering behavior; research has not yet examined associations between RF and other family interactions. We examined associations between RF and marital and coparenting quality for both wives and husbands. Reflective functioning was coded from Adult Attachment Interviews conducted during pregnancy. We assessed marital quality at 3.5 months, and coparenting quality at 13 months, after the birth of the target child. Wives’ higher RF was associated with higher levels of positive—and lower levels of negative—marital and coparenting interactions. Wives who were better able to reflect on their early experiences with their parents were involved in marital interactions that were more positive and supportive and less conflicted and undermining. Husbands’ RF did not predict marital or coparenting quality. These findings highlight the importance of reflective functioning in understanding family functioning.     

Infants’ recognition of objects using canonical color

We explored infants’ ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object placed side by side: a correctly colored picture (e.g., red strawberry) and an inappropriately colored picture (e.g., green-blue strawberry). The results showed that, overall, the 6- to 8-month-olds showed preference for the correctly colored pictures for color-specific objects, whereas they did not show preference for the correctly colored pictures for the non-color-specific object. The 5-month-olds showed no significant preference for the correctly colored pictures for all object conditions. These findings imply that the recognition of canonical color for objects emerges at 6 months of age.
