Numerosity discrimination was examined when items were varied in space-time position rather than in space only. Observers were instructed to indicate which of two adjacent streamsof visual events contained more items. The precision of numerosity discrimination of dynamic events was not remarkably different from that of static patterns. Two basic numerosity biases previously found for static dot patterns—inhibitory overestimation and satellite underestimation—were demonstrated for items distributed randomly over a spatiotemporal interval. It was also demonstrated that two streams, equated in the number and luminous energy of items, are not judged equal in their visible number if items in one of these two streams have longer duration than items in the second stream. These findings can be accounted for by the occupancy model of perceived numerosity (Allik & Tuulmets, 1991a) if it is supposed that the impact that each element has on its neighborhood is spread along both spatial and temporal coordinates. Perceived numerosity decreases with both spatial and temporal proximity between the-visual-items. Space and time have interchangeable effects on perceived numerosity: the amount of numerosity bias caused by the spatial proximity of items can also be produced by the properly chosen temporal proximity of items 相似文献
Previous studies have shown that participation in leisure time physical activity is related to better mental well-being and subjective health. However, the associations between different types of leisure time physical activities and different dimensions of mental well-being have rarely been studied. In addition, longitudinal research, analyzing possible causal relations between these variables, is lacking. To investigate these research questions, data gathered at ages 42 and 50 (present N = 303) for the Finnish Jyväskylä Longitudinal Study of Personality and Social Development were used. Physical activity was assessed as frequency of participation at ages 42 and 50, and at age 50 also as frequency of participation in different types of physical activities. Mental well-being was captured by emotional, psychological and social well-being and subjective health by self-rated health and symptoms. Cross-sectionally, different types of physical activities were related to different dimensions of well-being. Walking had positive associations with psychological and social well-being, rambling in nature with emotional and social well-being, and endurance training with subjective health. Rambling in nature was also positively related to subjective health but only among men. Longitudinally, mental well-being predicted later participation in leisure-time physical activity, whereas no longitudinal associations between subjective health and physical activity were found. The results suggest that leisure time physical activities are related to current mental well-being and subjective health in midlife. Across time, good mental well-being seems to be a resource promoting engagement in physical activity.
In the present study, the child-rearing goals of mothers of 4- to 6-year-old children from Estonia, Finland, and Sweden were compared. The developed Child-Rearing Goals Questionnaire consisted of three different tasks: open-ended questions, item rating, and item ranking. All mothers were similar in valuing highly self-maximization, but differed in emphasis on traditional child-rearing goals (e.g., conformity, obedience, politeness, being hard-working, etc.). The Swedish mothers tended to stress the characteristics connected with self-maximization as well as self-confidence and children's happiness, but did not value the traditional child-rearing goals. The Estonian mothers attached a great significance both to the traditional characteristics and to self-maximization. The Finnish mothers also stressed both traditional and non-traditional values, but to a lesser extent than the Estonians. The Swedish and Finnish mothers' child-rearing goals were relatively homogeneous. In contrast, the Estonian mothers were generally less focused on any specific goal. Mothers with a lower level of education stressed traditional goals more than mothers with a higher level of education. The results are discussed in the light of the possible effect different cultural contexts have on maternal child-rearing goals: bringing up children in stable welfare societies (such as Sweden and Finland) in contrast to a rapidly changing society (such as Estonia). 相似文献
The longitudinal study examined whether and how children’s temperament traits in particular but also their age, sex as well as maternal education and age predict maternal socialization values. The sample was drawn from the IDEFICS study and included 567 mothers from Estonia whose children were 2–9 years old at Time 0 and 4–11 years old at Time 1. The findings showed that children’s temperament at Time 0 predicted maternal socialization values at Time 1, but not vice versa. Mothers who perceived their child to be more imaginative at Time 0 considered self-maximization socialization values more important and social conformity-related values less important at Time 1. Child’s conscientiousness and extraversion were linked positively to social conformity-related socialization values. Older mothers and those with higher level of education put more emphasis on self-maximization socialization values. Children’s age and sex were not related to socialization values. 相似文献
Observers saw 234 different pairs of stochastically organized dot patterns and indicated which of the two patterns appeared to be more numerous. All of the data can be accounted for by supposing that the choice of the more numerous pattern is based on the determination of the occupancy indices of both patterns. Each dot is posited to have an impact upon its neighborhood in a constant occupancy radius R. The area of the stimulus plane occupied collectively by all dots provides a basis for judging relative numerosity; the pattern with the larger occupancy value is chosen as more numerous. The occupancy model, besides providing a general explanation of known numerosity illusions in strictly quantitative terms, can explain some puzzling aspects of numerosity perception. 相似文献
Mother's open-ended questions and elaborative statements during reminiscing were analysed for their content (child agency, co-agency, non-social, and social context) in three cultural contexts. Participants were 115 mothers and their 4-year-old children: 35 dyads from Berlin, Germany, 42 from Stockholm, Sweden, and 38 from Tallinn, Estonia. Across samples the most prominent content was talk about non-social context followed by co-agency and child agency. Tallinn mothers asked the children to talk about themselves, and Berlin mothers asked the children to talk about themselves together with other people, more frequently than they talked about these contents themselves. The content was related to the cultural orientations of mothers assessed through questionnaires: the Berlin mothers whose independence/ interdependence ratio was higher talked less about other people and asked the children fewer questions about other people; the Stockholm mothers with a higher independence/interdependence ratio talked more about child agency. In Tallinn both correlations existed on a trend level. The results are discussed in the light of common conversational practices and mothers' orientation to independence and interdependence in these cultural contexts. 相似文献
The current study examined maternal control of children across families with early adolescents from different sociocultural backgrounds. The intention was to find out whether belonging to the same ethnic group/language community (i.e., Estonian or Finnish) is more important for determination of child‐rearing attitudes and practices than sharing the immediate sociocultural context (i.e., Swedish society). In addition, attention was paid to the relationship between attitudes and behaviour. The results were obtained from three monocultural samples of Estonian, Swedish, and Finnish families living in their country of origin; two bicultural samples consisted of Estonian and Finnish families residing in Sweden. Two types of data—mothers' reported attitudes towards the importance of control over children's behaviour (the Control Scale) and video‐recorded real‐life verbal behaviour—were used to determine how the mothers' attitudes towards control relate to the behavioural control exhibited in their real‐life interactions. The study showed that the Finno‐Ugric mothers living in their countries of origin controlled their children's behaviour significantly more frequently than those Finno‐Ugric mothers who live in Sweden, but both Estonian samples outperformed Finns in their reported control attitudes. The Swedish mothers were the least directive among monocultural mothers both in maternal beliefs and in real‐life behaviour, but they differed from Estonian and Finnish mothers residing in Sweden only in their lower scores on the Control Scale. The study revealed that mothers' real‐life control behaviour corresponded rather modestly to their reported attitudes toward the importance of controlling children. Analyses of actual mother—child interaction showed that only the Estonian mothers living in Estonia actually put their relatively high scores on the Control Scale into practice in real‐life interactions with their children. Finally, some characteristics of Estonian, Finnish, and Swedish languages and cultures are discussed that might determine the cultural differences in child rearing that emerged. 相似文献
The present study explored gender differences in emerging language skills in 13,783 European children from 10 non‐English language communities. It was based on a synthesis of published data assessed with adapted versions of the MacArthur‐Bates Communicative Development Inventories (CDIs) from age 0.08 to 2.06. The results showed that girls are slightly ahead of boys in early communicative gestures, in productive vocabulary, and in combining words. The difference increased with age. Boys were not found to be more variable than girls. Despite extensive variation in language skills between language communities, the difference between girls and boys remained. This suggests that the difference is caused by robust factors that do not change between language communities. 相似文献
This study examines mother-child reminiscing conversations with respect to variation in use and function of mothers’ elaborations, the nature of children's memory elaborations, and the connections between the two, in three Western middle-class cultures where autonomy is valued over relatedness. Mothers participated with their 4-year-old children (35 dyads from Berlin, Germany, 42 dyads from Stockholm, Sweden, and 38 from Tallinn, Estonia). Mothers’ open-ended questions predicted children's memory elaborations in Estonian dyads, mothers’ statements and verbal confirmation did so in German dyads, and verbal confirmations did so in Swedish dyads. Number of children's elaborations was similar in all three groups, but Estonian mothers were less elaborative than Swedish and German mothers. These findings contrast with previous research in which number of child elaborations has been linked to number of mother elaborations. The results suggest that different aspects of elaborative style function differently. The differences are discussed in light of culturally rooted meanings and practices of talking. 相似文献
