Identification and conceptualization of procedural chunks in chess

When it comes to cognitive architecture and human information processing, chunks are one of the best known and most recognized constructs. Nevertheless, the nature of chunks is still very elusive, especially when it comes to chunks in procedural knowledge. This study deals with basic features of procedural information processing and examines the manifestation of chunks in procedural knowledge. The participants' task was to reconstruct sequences of chess moves. Chess was chosen as an experimental domain, because of its complexity, well-defined rules and standardized measure of chess player strength. From the results we conclude that short-term memory capacity is determined by the combination of the size and amount of procedural chunks recalled to the short-term memory. We have shown that on average, participants with more specialized knowledge operated faster and with larger chunks of procedural information than participants with less specialized knowledge. We have shown that in procedural information processing, the level of expertise and the sorting order of the retrieved information are important factors that influence the amount of procedural chunks retained in the short-term memory. Therefore, the capacity of short-term memory in complex situations cannot be expressed as a simple concept.     

The Influence of Unrestricted Information Exchange on Willingness to Share Information With Outsiders

This study addressed how engaging in different forms of information exchange within a group is related to group members' willingness to share risk information with outsiders. Drawing from social exchange theories, we focused on 3 unrestricted forms of information exchange: pure‐generalized, group‐generalized, and productive. We hypothesized that individuals' intentions to share information with outsiders would be associated positively with engagement in pure or group‐generalized exchanges and negatively with productive exchange. The hypotheses were supported with data from a national survey of U.S. growers (N = 452) that examined their information‐sharing behaviors with other parties inside and outside their local region. The findings have broad implications for understanding information sharing within and across groups.     

The relationship between information processing style and information seeking,and its moderation by affect and perceived usefulness: Analysis vs. procrastination

We examined the relationship between information processing style and information seeking, and its moderation by anxiety and information utility. Information about Salmonella, a potentially commonplace disease, was presented to 2960 adults. Two types of information processing were examined: preferences for analytical or heuristic processing, and preferences for immediate or delayed processing. Information seeking was captured by measuring the number of additional pieces of information sought by participants. Preferences for analytical information processing were associated positively and directly with information seeking. Heuristic information processing was associated negatively and directly with information seeking. The positive relationship between preferences for delayed decision making and information seeking was moderated by anxiety and by information utility. Anxiety reduced the tendency to seek additional information. Information utility increased the likelihood of information seeking. The findings indicate that low levels of anxiety could prompt information seeking. However, information seeking occurred even when information was perceived as useful and sufficient, suggesting that it can be a form of procrastination rather than a useful contribution to effective decision making.     

Factors affecting perceived safety and enjoyment based on driver experience

A positive driving experience, especially for older drivers, increases the attention to the emotional dimensions of driving, such as the driver’s perceived safety. Therefore, this study empirically presents factors affecting driver experience and compares them between older and younger drivers. Consequently, we conducted a face-to-face survey on elderly and young drivers and analyzed the data of 246 drivers using structural equation modeling. The analysis presented measurements and structural model evaluations. Considering the analysis, it was found that driving-related information and car-exterior context affect the perceived safety and enjoyment of a driver’s experience. Additionally, car-exterior context exerts a greater influence on the perceived safety and enjoyment of the elderly drivers’ group than the young drivers’ group. The results of this study will empirically contribute to the satisfaction of driver experience and perceived safety improvement in the future. It also provides a basis for the development of driving interfaces to improve the quality of the driving experience of the elderly.     

Connections Between Family Communication Patterns,Person‐Centered Message Evaluations,and Emotion Regulation Strategies

In this study, we theorize that family communication patterns (FCPs) and 2 emotion regulation strategies (reappraisal and suppression) explain variations in person‐centered (PC) supportive message evaluations. Specifically, we forward an emotion regulation model that predicts reappraisal and suppression will mediate the relation between FCPs and PC message evaluations. Results (N = 361) suggest that conversation orientation positively predicted reappraisal and negatively predicted suppression; conformity orientation positively predicted suppression only. Reappraisal positively and suppression negatively predicted the extent to which people discriminated among PC message evaluations. Reappraisal also mediated the relation between conversation orientation and PC message evaluations. These results have implications for how capable people are to evaluate and ultimately profit from beneficial support when coping with negative emotions.
