Perceptions of the ethicality of favors at work in Asia: An 11-society assessment
No full textWe explore macro-level factors that shape perceptions of the ethicality of favors in Asian workplaces using the subordinate influence ethics (SIE) measure. We also expand and use the crossvergence model to examine the cross-level relationship between socio-cultural (i.e., traditional/secular; survival/self-expression; in-group favoritism) and business ideology influences (i.e., human development level, control of corruption) on perceptions of favor-seeking at work. This study examines the perceptions of a total of 4,325 managers and professionals in a diverse set of 11 Asian societies: China, Hong Kong, India, Indonesia, Malaysia, Pakistan, Singapore, South Korea, Taiwan, Thailand, and Vietnam. Our investigation focuses on both the "softer" (image management) and "harder" (self-serving) sides of subordinate influence attempts to seek favors, as well as the degree of ethical differentiation across these societies. Key results based on hierarchical linear modeling (HLM) suggest that both the World Value Survey's socio-cultural values as well as in-group favoritism contribute to our understanding of influence behaviors in Asia. Likewise, level of human development and control of corruption also appear to be promising predictors of influence ethics. In sum, our results suggest that widening the scope of the crossvergence conceptualization of socio-cultural and business ideology influences engender a better understanding of differences in attitudes toward subordinate use of favoritism across Asian societies
Optimal viewing position effects in the processing of isolated Chinese words
No full textPrevious studies have found that words are identified most quickly when the eyes fixate near the word center (the Optimal Viewing Position, OVP) in alphabetic languages. Two experiments were performed to determine the presence of OVP effects during the processing of isolated Chinese words. Participants' eye movements were recorded while they performed a lexical decision task. The results suggest that Chinese readers exhibit OVP effects and that the OVP tends to be the first character for 2-character words. For 3- and 4-character words, the OVP effects appear as a U-shaped curve with a minimum towards the second character. As fixations deviate from the OVP, word processing times increase at a rate of 30-70 ms per character, and fixation duration is strongly influenced by the initial viewing position. Moreover, the present study did not observe an I-OVP effect for first fixation durations nor a fixation-duration trade-off in two-fixation cases in the case of isolated Chinese words processing.

Aging, Culture, and Memory for Socially Meaningful Item-Context Associations: An East-West Cross-Cultural Comparison Study
No full textResearch suggests that people in Eastern interdependent cultures process information more holistically and attend more to contextual information than do people in Western independent cultures. The current study examined the effects of culture and age on memory for socially meaningful item-context associations in 71 Canadians of Western European descent (35 young and 36 older) and 72 native Chinese citizens (36 young and 36 older). All participants completed two blocks of context memory tasks. During encoding, participants rated pictures of familiar objects. In one block, objects were rated either for their meaningfulness in the independent living context or their typicality in daily life. In the other block, objects were rated for their meaningfulness in the context of fostering relationships with others or for their typicality in daily life. The encoding in each block was followed by a recognition test in which participants identified pictures and their associated contexts. The results showed that Chinese outperformed Canadians in context memory, though both culture groups showed similar age-related deficits in item and context memory. The results suggest that Chinese are at an advantage in memory for socially meaningful item-context associations, an advantage that continues from young adulthood into old age
Prospective memory performance in patients with drug-naive, first-episode psychosis
No full textSchizophrenia is associated with an impairment of prospective memory (PM) which refers to the ability to remember to carry out an intended action in the future. However, most of these studies were limited to chronic samples. The current study examined the event-based PM and time-based PM using a dual-task paradigm in 22 drug-naive, first-episode psychosis (FEP) patients and 23 healthy controls. Results indicated that FEP patients performed significantly poorer than healthy controls in both event-based and time-based PM. However, the significant difference in time-based PM disappeared after controlling for working memory. Correlation analysis indicated that both types of PM did not correlate with positive symptoms or negative symptoms, duration of illness, or duration of untreated psychosis. However, time-based PM was correlated with the general psychopathology subscale of the PANSS. Taken together, these findings suggest that PM deficits are present in drug-naive FEP patients; impairment of event-based PM appears to occur independently, whereas time-based PM impairment may be, in part, a secondary consequence of a working memory deficit.

The Human Altruistic Punishment: From The Perspective of Cognitive Neuroscience
No full textAltruistic punishment is very common in human life, which is an effective mechanism enforcing group cooperation and social norm. From perceiving the transgressions to administering costly punishment, potential punishing requires a series of cognitive and affective processes, including fairness judgment, reward processing, self-control, mentalizing, etc., and their underlying neurophysiological mechanisms. Cognitive neuroscience provides alternative perspective and paradigm for understanding human punishment behavior. Based on the latest findings, the neurophysiological mechanisms of altruistic punishment are reviewed and discussed in this article
Can the memory of an object be enhanced by imagining its loss?
No full textPrevious investigations examining salient memories have demonstrated that personal memories that are important to individuals and contain emotional information are better remembered than neutral events. Using behavioral and brain-imaging experiments, the present studies explored whether the previous finding was applicable imagined loss. In a behavioral experiment, a free recall paradigm was used to compare the memory performance of individuals who imagined loss with that of individuals who imagined importance. The superior memory performance conferred by imagining loss was constrained to ordinary items of low to medium importance and did not generalize to vital items. Moreover, brain imaging evidence revealed that the activation in certain brain regions was stronger when participants were imagining the loss of ordinary items of low to medium importance compared to vital items. These brain regions included cognitive effort-related areas (such as the parietal cortex and middle prefrontal cortex) and areas related to emotional experiences and emotion-related memories (such as the amygdala, parahippocampal gyms, and posterior cingulate gyms). Our study provides a new way of exploring the superior memory performance when imagining loss and enriches the literature on memory enhancement by contributing to a deeper understanding of the psychological mechanisms related to the imagining of vital losses
The Advantage of Word-Based Processing in Chinese Reading: Evidence From Eye Movements
No full textIn 2 experiments, we tested the prediction that reading is more efficient when characters belonging to a word are presented simultaneously than when they are not in Chinese reading using a novel variation of the moving window paradigm (McConkie & Rayner, 1975). In Experiment 1, we found that reading was slowed down when Chinese readers could not see characters belonging to a word simultaneously compared to when they could do so. In Experiment 2, when Chinese readers could choose whether the 2 characters in the moving window contained a word or 2 characters that did not constitute a word, they had a clear tendency to look at 2 characters belonging to a word simultaneously. The results of the current study provide strong evidence that character processing is affected by word knowledge and the processing of other characters belonging to the same word in Chinese reading, and add to a growing body of evidence demonstrating that words do have psychological reality for Chinese readers. The results also suggest that the eye movement control strategy of Chinese readers is rather flexible in that it can be adjusted online to modify the characteristics of the window
Evidence for cerebellar dysfunction in Chinese children with developmental dyslexia: an fMRI study
No full textNumerous studies reported that developmental dyslexia in alphabetic languages was associated with a wide range of sensorimotor deficits, including balance, motor skill and time estimation, explained by skill automatization deficit hypothesis. Neural correlates of skill automatization deficit point to cerebellar dysfunction. Recently, a behavioral study revealed an implicit motor learning deficit in Chinese children with developmental dyslexia in their left hands, indicating left cerebellar dysfunction. Using functional magnetic resonance imaging (fMRI), our study examined the brain activation during implicit motor learning in 9 Chinese dyslexic and 12 age-matched children. Dyslexic children showed abnormal activations in the left cerebellum, left middle/medial temporal lobe and right thalamus compared with age-matched children during implicit motor learning. These findings provide evidence of cerebellar abnormality in Chinese dyslexic people. Furthermore, dysfunction of the left cerebellum in Chinese dyslexia is inconsistent with the right cerebellum abnormalities that were reported by studies on alphabetic-language dyslexia, suggesting that neurobiological abnormalities of impaired reading are probably language specific
Polymorphisms of the Kappa Opioid Receptor and Prodynorphin Genes: HIV Risk and HIV Natural History
No full textObjective: Studies indicate cross-desensitization between opioid receptors (eg, kappa opioid receptor, OPRK1) and chemokine receptors (eg, CXCR4) involved in HIV infection. Whether gene variants of OPRK1 and its ligand, prodynorphin (PDYN), influence the outcome of HIV therapy was tested. Methods: Three study points, admission to the Women's Interagency HIV Study, initiation of highly active antiretroviral therapy (HAART), and the most recent visit, were chosen for analysis as crucial events in the clinical history of the HIV patients. Regression analyses of 17 variants of OPRK1 and 11 variants of PDYN with change of viral load (VL) and CD4 count between admission and initiation of HAART and initiation of HAART to the most recent visit to Women's Interagency HIV Study were performed in 598 HIV+ subjects, including African Americans, Hispanics, and Whites. Association with HIV status was done in 1009 subjects. Results: Before HAART, greater VL decline (improvement) in carriers of PDYN IVS3+189C>T and greater increase of CD4 count (improvement) in carriers of OPRK -72C>T were found in African Americans. Also, greater increase of CD4 count in carriers of OPRK1 IVS2+7886A>G and greater decline of CD4 count (deterioration) in carriers of OPRK1 - 21205G>A were found in Whites. After HAART, greater decline of VL in carriers of OPRK1 IVS2+ 2225G. A and greater increase of VL in carriers of OPRK1 IVS2+ 10658G. T and IVS2+ 10963A. G were found in Whites. Also, a lesser increase of CD4 count was found in Hispanic carriers of OPRK1 IVS2 + 2225G. A. Conclusions: OPRK1 and PDYN polymorphisms may alter severity of HIV infection and response to treatment
