What are numbers?

A number is the number of a class which is an objective, nonactual, mathematical object. The concept of class is analyzed and it is concluded that a number is the number of a pure founded class. A tempting strategy of explaining numbers away is rejected. Some well‐known definitions of numbers are analyzed and it is concluded that this analysis purports the thesis that the unique notion of number does not exist. Numbers are conventional. Nevertheless, an argument is offered purporting the thesis that von Neumann's ordinal numbers are the ordinal numbers. Accordingly, the corresponding von Neumann's cardinal numbers are the numbers.     

Psychological cost-benefit as an intervening construct in career choice models

A causal model for career choice was outlined, encompassing psychological cost-benefit-profit as a central intervening construct. The model was applied to the career choice (education vs work) after high school graduation and tested on longitudinal data from 173 students. The main problem concerned the relationship among the components in the causal career choice model, using multiple correlation and path analysis as tools. The results showed clear sex differences. For boys, the model was a rather powerful predictor of career choice (R = 0.70), and Psychological profit with regard to continued education had a clear direct effect as well as an indirect effect on career choice. For girls, the predictive validity was low (R = 0.35) and Psychological profit affected career choice only indirectly via Educational aspiration.     

Sensorimotor synchronization: Motor responses to regular auditory patterns

Subjects (N = 32) were asked to synchronize a motor response with tones in auditory patterns. These patterns were created from six tones and six intertone intervals of equal duration. The pitch of the first tone differed from the others. It was found that subjects used three types of timing in their motor response: (1) the first intertone interval was prolonged and the second interval was shortened, (2) the second intertone interval was prolonged and the first interval was shortened, and/or (3) the first interval and the second interval were of approximately the same length. The prolongation of the fifth interval was observed during all three types of timing. The results are explained using the concept of suprasegmental control of timing, which explains a prolongation of intervals at critical control point of the patterns. The occurrence of three different strategies of timing is discussed in connection with similar principles in musical performance.     

COMPARISONS OF SOCIO-POLITICAL ATTITUDES BETWEEN TWO DEMOCRATIC SOCIETIES

Three-hundred and twenty-seven Australian and 192 Swedish psychology students were compared with respect to four aspects of socio-politico attitudes: (a) differences in average levels for items and dimensions, (b) differences in degrees of consensus for specific issues (items), (c) differences in the structures of socio-politico attitudes and (d) differences in the profiles of attitudes across relevant items and dimensions. Analyses of variance showed that, in general, Swedes were significantly less conservative than Australians. The largest difference between the two samples were found for the dimension of punitiveness where Swedes were found to be much less punitive than Australians. The results also disclosed that there was greater ideological consensus and consistency among Swedes than among Australians. In line with earlier cross-cultural research, the results also disclosed a relatively high level of ideological profile and structural similarity among the two western nations.

视觉注意捕获的快速脱离假说与信号抑制假说

快速脱离假说和信号抑制假说都是将传统的自下而上捕获和自上而下控制结合起来的混合模式假说。快速脱离假说认为突显干扰物总能在第一时间自下而上地捕获注意, 当突显干扰物与任务要求不符时, 注意会迅速脱离该位置。信号抑制假说认为突显干扰物都会产生“注意我”的信号, 当突显干扰物与任务要求不符时, 该信号会被自上而下地抑制以阻止注意捕获发生。前者相关的研究多采用空间线索提示范式和眼动脱离范式, 实验中被试采取独子探测策略, 而后者相关的研究多采用额外单例范式的变式, 实验中被试采取特征探测策略。未来研究应采用不同的刺激类型和实验方法进一步为两个假说提供证据支持, 同时要关注奖赏、训练等因素对“捕获-脱离”和“信号-抑制”的影响。     

Refugee students' perspectives on inclusive and exclusive school experiences in Austria

This paper examines refugee students' experiences in the Austrian mainstream school system. It highlights four areas: school connectedness, social exclusion, support systems and friendships. In the study, 55 refugee students between 8 and 21 years old enrolled in primary and secondary education participated in a semi-structured interview. Data were analysed with directed qualitative content analysis, whereby codes were created deductively and inductively. Students stressed the importance of schooling in order to prosper in the future, particularly through language acquisition. Peers and bilingual teachers played an important role in their efforts to learn German and develop feelings of belonging in the school system. While language acquisition was important for the students, they indicated that other support measures (i.e., remedial education) were largely absent. Further, half of the students reported bullying experiences (verbal, social and physical) associated with their refugee status, language proficiency and religious affiliation. This study has implications for school professionals. The scope of support refugee students receive at school must be broadened, forced migration should be addressed in school in order to counteract negative effects of bullying students receive due to their refugee status and school connectedness can be promoted by hiring staff from diverse cultural backgrounds.
