Abstract

Canal connecting Elbląg with Ostróda was built in the XIX century to transport corn to the port of Elbląg. Due to economic and political changes it never played its economic function. Now it is a tourist attraction. The canal is thus of some tourist value which is difficult to assess. Tourist value of the Elbląg Canal was assessed with the travel cost method (TCM) within the study carried out in 2003. The study allowed for estimating the object’s value based on its usefulness expressed by inclination to payment. Three groups of users were distinguished when analysing the demand for recreational canal’s services: tourists using ships of the Elbląg–Ostróda Navigation Company, individual sailors and anglers. Total tourist value of the canal calculated as NPV of the annual value of canal’s services depends on adopted interest rate. At a rate of 3.2% the value is 328 thous. PLN (73.9 thous. euro), at a rate of 4% – 282 thous. PLN (63.5 thous. euro), while at 8% interest rate it decreases to 160 thous. PLN (36.0 thous. euro).

Abstract

Previous research showed that children can exhibit preferences for social categories already at preschool age. One of the crucial factors in the development of children’s attitudes toward others is children’s observation and imitation of adults’ nonverbal messages. The aim of our study is to examine whether children’s tendency to perceive and follow nonverbally expressed attitudes toward other people is related to ingroup bias, i.e. the tendency to favor one’s own group over other groups. We examined 175 preschool children (age in months: 61–87; M = 72.6, SD = 6.53) presenting them with a video of a conversation between a message sender and a message recipient. The study was conducted in a minimal group paradigm. We found that children accurately identified the message sender’s attitude toward the recipient and also generalized this attitude to other members of the new group. We also found explicit ingroup bias among children from the message sender’s group. However, no generalization of the sender’s attitude to other ingroup members was found. The results are discussed in reference to previous findings on the role of imitation of adult’s non-verbal behavior for the development of social attitudes among children.

Abstract

In the present study, we analyse the influence of goal maintenance and goal change on the efficiency of executive control. Although there is empirical evidence on the impact of goal maintenance and task-switching on executive control, little is known about the consequences of changing between processing goals (e.g., speed or accuracy goals). We assessed the influence of changing between speed and accuracy goals while performing a task-switching procedure that requires social categorization. Experiment 1 included frequent goal changes, whereas Experiment 2 included one goal change across the experimental session. The results showed that both goals influence general performance and flexibility. A comparison between experiments suggested that frequent goal change (Experiment 1) resulted in worse performance and lower flexibility overall, compared to sequential goal change (Experiment 2). Frequent goal change was also associated with increased difficulties in pursuing the accuracy goal. The implications regarding the role of goal maintenance and goal change on executive control are discussed, as well as new research possibilities.
