Inertia and memory in ambiguous visual perception 总被引:1,自引:0,他引:1

Perceptual multistability during ambiguous visual perception is an important clue to neural dynamics. We examined perceptual switching during ambiguous depth perception using a Necker cube stimulus, and also during binocular rivalry. Analysis of perceptual switching time series using variance–sample size analysis, spectral analysis and time series shuffling shows that switching times behave as a 1/f noise and possess very long range correlations. The long memory feature contrasts sharply with the traditional satiation models of multistability, where the memory is not incorporated, as well as with recently published models of multistability and neural processing, where memory is excluded. On the other hand, the long memory feature favors the concept of “dynamic core” or coalition of neurons, where neurons form transient coalitions. Perceptual switching then corresponds to replacement of one coalition of neurons by another. The inertia and memory measures the stability of a coalition: a strong and stable coalition has to be won over by another similarly strong and stable coalition, resulting in long switching times. The complicated transient dynamics of competing coalitions of neurons may be addressable using a combination of functional imaging, measurement of frequency-tagged magnetoencephalography and frequency-tagged encephalography, simultaneous recordings of groups of neurons in many areas of the brain, and concepts from statistical mechanics and nonlinear dynamics theory. 相似文献

Against the backdrop of COVID-19 pandemic, we draw on family systems theory to elucidate how daily work-from-home status (WFH) affects both members in dual-earner couples. We propose that the WFH exerts intra-individual and inter-individual influences on employees’ and their partners’ work task and family task completion and their subsequent reactions to their work and family experiences. We examined the hypothesized relationships with two daily survey studies on dual-earner couples conducted during the pandemic (i.e., 1,559 daily responses of 165 dual-earner couples from China in Study 1, and 773 daily responses of 57 dual-earner couples from South Korea in Study 2). The two studies provide converging results that working from home (vs. office) increased employees’ family task completion for both husbands and wives and that wives working from home (vs. office) decreased husbands’ family task completion. Further, in both studies, daily work task completion increased felt guilt toward family (for wives only) through increased work-family conflict, and daily family task completion increased psychological withdrawal from work through increased family-work conflict for both husbands and wives. Moreover, we found in Study 2 that on days when husbands had flexible work schedule, wives completed more work tasks when working from home (vs. office) and that on days when wives had inflexible work arrangement, husbands completed more family tasks when working from home (vs. office). Across the two studies, there were no clear gender-difference patterns in husbands’ and wives’ work and family experiences. 相似文献

Mere ownership effect is the phenomenon that people tend to value what they own more than what they do not own. This classic effect is considered robust, yet effect sizes vary across studies, and the effect is often confused for or confounded with other classic phenomena, such as endowment or mere exposure effects. We conducted a pre-registered meta-analysis of 26 samples published before 2019 (N = 3024), which resulted in psychological ownership on valuing effect of g ∼ 0.57 [0.46, 0.69]. Suggestive moderator analyses supported the use of replica as the strongest moderators. Mere ownership effects were different from the null across all moderator categories and in most publication bias adjustments. We consider this as suggestive evidence that psychological owning leads to valuing, yet caution that much more research is needed.

本实验采用一次性味觉厌恶回避学习,研究2日龄雏鸡左眼视剥夺24小时后的记忆形成过程,并与左眼视剥夺2小时后的记忆形成过程进行比较,同时利用免疫组化技术,观察并比较单眼视剥夺不同时程及单眼学习后Jun样蛋白在雏鸡脑内不同区域(HV和LPO)的表达。结果表明:1.视剥夺左眼24小时后对雏鸡的短时记忆、中时记忆和长时记忆均无明显影响,但中时记忆保持水平略低于双眼学习条件下的中时记忆保持水平。这与视剥夺2 相似文献

本实验用IBM PC/XT计算机对30名青年人和9名中年人进行图形辨别负荷实验。结果表明:(1)同时呈现的图形数量(任务困难度)、允许辨别的时间(时间忙碌程度)和年龄都是影响被试业绩的因素。(2)在需辨别的图形数较多且有辨别速度要求的任务中,不宜选用中年人。(3)通过实验求出青年人图形辨别经验公式Y=De~(B/X),D(N)=183.1441-2.3206N 0.0249N~2,B(N)=-2.0379-0.1427N 0.0008N~2。据此公式可求出在此情境下,对一定数量的图形(N),在一定时间限定内(X)的图形正确辨别率(Y)。 相似文献

离职曾被视作组织中的"问题"而受到学术界的重视。传统离职研究更关注通过改变员工的态度来减少离职,进而降低离职对组织产生的负面影响,具有鲜明的组织立场。然而离职的本质是员工个体的决策。无边界职业生涯背景下,面对更加多样化的生涯选择,员工在离职决策中的主体性更加凸显,离职研究需要重回决策者中心,重新聚焦决策者:(1)以决策者为中心探讨离职影响因素;(2)探讨决策者制定离职决策的内在过程;(3)关注员工离职的实际行为及后果。 相似文献
