Cross-Cultural Comparisons of Adults’ Childhood Recollections: How are Peak-Experiences Described in China and Portugal?

Peak experiences are joyous and fulfilling moments in life, and thought to be associated with happiness and well-being. However, whether peak experiences vary from culture to culture is still under-researched. The current study investigated the autobiographical memories of peak experiences in Portugal and China. College students from Portugal and Mainland China (N = 161) reported their memory of a peak-experience occurring before the age of 14 and provided a self-rating on its enduring impact. We found that participants from Portugal reported peak-experiences involving a developmental landmark more frequently than did Mainland Chinese. In contrast, Mainland Chinese reported peak-experiences involving serenity more frequently than did Portuguese participants. Although Mainland Chinese provided more details about their peak-experiences, their narratives were more generic and emotionally mild. In particular, memory specificity (specific vs. general) significantly mediated the association between culture and developmental landmark, whereas memory emotionality (low arousal emotions) significantly mediated the link between culture and serenity. This study extends previous research on youthful peak-experiences to a cross-cultural context by incorporating measures of autobiographical memory to analyze variations between these two cultural groups.     

Electronic Friend or Virtual Foe: Exploring the Role of Competitive and Cooperative Multiplayer Video Game Modes in Fostering Enjoyment

Industry and scholarly sources both argue that multiplayer gaming and competition are important factors in creating enjoyment, but relatively little empirical work demonstrates this claim. This study uses an experimental design (N = 139) to evaluate the effects of different multiplayer modes on enjoyment, allowing participants to interact naturally with a confederate partner and manipulating both game mode and partner behavior in a game of Madden '08. Results show that enjoyment is significantly enhanced by the combination of competitive play and a friendly partner, and demonstrate that the quality of interpersonal interaction only partly accounts for this.     

When Choices Are Not Personal: The Effect of Statistical and Social Cues on Children's Inferences About the Scope of Preferences

Individual choices are commonly taken to manifest personal preferences. The present study investigated whether social and statistical cues influence young children's inferences about the generalizability of preferences. Preschoolers were exposed to either 1 or 2 demonstrators’ selections of objects. The selected objects constituted 18%, 50%, or 100% of all available objects. We found that children took a single demonstrator's choices as indicative only of his or her personal preference. However, when 2 demonstrators made the same selection, then children inferred that it generalized to other agents of the same kind as the original demonstrator's, but not to agents of a different kind. Lastly, only when both demonstrators blatantly violated random selection (i.e., in the 18% condition) did children generalize the preference even to an agent of a different kind. Thus, from a young age, social and statistical cues inform children's naïve sociology.     

Work flow policy and within-worker and between-workers variability in performance

Work flow policies are shown to induce a change in average between-workers variability (worker heterogeneity) and within-worker variability in performance times. In a laboratory experiment, the authors measured the levels of worker heterogeneity and within-worker variability under an individual performance condition, a work sharing condition, and a fixed assignment condition. The work sharing policy increased the levels of worker heterogeneity and worker variability, whereas the fixed assignment policy decreased them. These effects, along with work flow policy main effects on mean performance times and variability are examined. This article represents an initial step in understanding effects that may be important in the selection of an operating policy, the ignorance of which may lead to costly misestimates of performance.

洛阳汉代墓室壁画是中国的艺术瑰宝,是迄今发现的能够代表汉代绘画发展水平的杰作,其古拙的艺术风格和娴熟的绘画技法,对中国绘画艺术产生过积极影响,在中国美术史上占有极其重要的地位。本文旨在探讨洛阳汉墓壁画中表现的天人合一、阴阳五行的儒道思想观念。在那些形象生动、奇形怪状的绘画艺术背后,蕴藏了汉代先民对天地自然,对社会生活的理解,表达了他们对生命世界的永恒追求,展现了中国神秘文化的博大精深。     

Limitations of object-based feature encoding in visual short-term memory

The present study investigated object-based feature encoding in visual short-term memory for 2 features within the same dimension that occur on different parts of an object. Using the change-detection paradigm, this experiment studied objects with 2 colors and objects with 2 orientations. Participants found it easier to monitor 1 rather than both features of such objects, even when decision noise was properly controlled for. However, no object-based benefit was observed for encoding the 2 features of each object that were of the same dimension. When similar stimuli were used but the 2 features of each object were from different dimensions (color and orientation), an object-based benefit was observed. These results thus impose a major constraint on object-based feature encoding theories by showing that only features from different dimensions can benefit from object-based encoding.     

Feature integration across parts in visual search

In the present study, participants searched for a conjunction of color and orientation either from the same part of an object (same-part display), or from different parts of an object (different-part display). While no difference was found between the two display conditions in single feature searches, conjunction search in the same-part display was significantly faster than that in the different-part display. This same-part advantage applies to both the inner part as well as the outer part of an object. These results suggest that features are more readily integrated if they are from the same part of an object than if they are from different parts of an object. The formation of object part representations thus influences how features are integrated and encoded during visual information processing.     

Content differences for abstract and concrete concepts

Concept properties are an integral part of theories of conceptual representation and processing. To date, little is known about conceptual properties of abstract concepts, such as idea. This experiment systematically compared the content of 18 abstract and 18 concrete concepts, using a feature generation task. Thirty-one participants listed characteristics of the concepts (i.e., item properties) or their relevant context (i.e., context properties). Abstract concepts had significantly fewer intrinsic item properties and more properties expressing subjective experiences than concrete concepts. Situation components generated for abstract and concrete concepts differed in kind, but not in number. Abstract concepts were predominantly related to social aspects of situations. Properties were significantly less specific for abstract than for concrete concepts. Thus, abstractness emerged as a function of several, both qualitative and quantitative, factors.     

Infants' knowledge of objects: beyond object files and object tracking

Two independent research communities have produced large bodies of data concerning object representations: the community concerned with the infant's object concept and the community concerned with adult object-based attention. We marshal evidence in support of the hypothesis that both communities have been studying the same natural kind. The discovery that the object representations of young infants are the same as the object files of mid-level visual cognition has implications for both fields.     

COVID-19 non-death loss and acceptance coping: A 3-wave cross-lagged panel analysis

Numerous individuals have lost loved ones during the COVID-19 pandemic while millions of others have also experienced ongoing pervasive non-death loss. The understanding of how people deal with non-death loss is still relatively limited. Incorporating theory of coping and loss, this study examines the reciprocal relationship between non-death loss and acceptance coping. Based on the results of a cross-lagged panel model involving 314 participants in China, we found that before the end of the zero-Covid policy, non-death loss at Time 1 predicted less acceptance coping at Time 2, but in the opening up stage in late 2022, non-death loss at time 2 did not predict acceptance coping at time 3. The findings have significant implications for understanding the interplay between non-death loss and acceptance coping and highlights abrupt psychological changes during the COVID-19 pandemic.
