Opis:
Learning a foreign language in the context of formal education often imposes on students the management of difficult tasks. This demands an adoption of adequate coping behaviour (achievement vs. avoidance). Easy tasks reduce learning opportunities, while too difficult ones lead to escape-motivated problem behavior. For the purpose of the present research it is proposed that the level of FL task difficulty is related to coping behaviour. The empirical results demonstrate that students who perceive FL tasks as difficult apply more avoidance strategies. Apart from that, students with higher and lower levels of task difficulty use similar amounts of achievement strategies. It follows that the implementation of achievement coping is independent from the level of task difficulty.

Opis:
The paper presents a new elastic scheduling task model which has been used in the uniprocessor node of a control measuring system. This model allows the selection of a new set of periods for the occurrence of tasks executed in the node of a system in the case when it is necessary to perform additional aperiodic tasks or there is a need to change the time parameters of existing tasks. Selection of periods is performed by heuristic algorithms. This paper presents the results of the experimental use of an elastic scheduling model with a GRASP heuristic algorithm.

Opis:
Using mobile devices such as smartphones or iPads for various interactive applications is currently very common. In the case of complex applications, e.g. chess games, the capabilities of these devices are insufficient to run the application in real time. One of the solutions is to use cloud computing. However, there is an optimization problem of mobile device and cloud resources allocation. An iterative heuristic algorithm for application distribution is proposed. The algorithm minimizes the energy cost of application execution with constrained execution time.

Opis:
The main objective of this study was to examine whether children’s ability to justify their action predictions in terms of mental states is related, in a similar way as the ability to predict actions, to such aspects of executive function (EF) as executive control and working memory. An additional objective was to check whether the frequency of different types of justifications made by children in false-belief tasks is associated with aforementioned aspects of EF, as well as language. The study included 59 children aged 3-4 years. The ability to predict actions and to justify these predictions was measured with false-belief tasks. Luria’s hand-game was used to assess executive control, and the Counting and Labelling dual-task was used to assess working memory capacity. Language development was controlled using an embedded syntax test. It was found that executive control was a significant predictor of the children’s ability to justify their action predictions in terms of mental states, even when age and language were taken into account. Results also indicated a relationship between the type of justification in the false-belief task and language development. With the development of language children gradually cease to justify their action predictions in terms of current location, and they tend to construct irrelevant justifications before they begin to refer to beliefs. Data suggest that executive control, in contrast to language, is a factor which affects the development of the children’s ability to justify their action predictions only in its later phase, during a shift from irrelevant to correct justifications.

Opis:
Earlier research by the author brought about findings suggesting that people in a special way process words related to demands of a problem they previously solved, even when they do not consciously notice this relationship. The findings concerned interference in the task in which the words appeared, a shift in affective responses to them that depended on sex of the participants, and impaired memory of the words. The aim of this study was to replicate these effects and to find out whether they are related to working memory (WM) span of the participants, taken as a measure of the individual’s ability to control attention. Participants in the experimental group solved a divergent problem, then performed an ostensibly unrelated speeded affective classification task concerning each of a series of nouns, and then performed an unexpected cued recall task for the nouns. Afterwards, a task measuring WM span was administered. In the control group there was no problem-solving phase. Response latencies for words immediately following problem-related words in the classification task were longer in the experimental than in the control group, but there was no relationship between this effect and WM span. Solving the problem, in interaction with sex of the participants and, independently, with their WM span, influenced affective responses to problem-related words. Recall of these words, however, was not impaired in the experimental group.

Opis:
The purpose of the study was to examine whether older adults show an emotional interference effect in a Stroop task, and whether their RTs differ with regard to age, gender and tendencies of mood regulation (to improvement and/or deterioration). The sample consisted of 60 participants at the age from 65 to 85. Emotional version of Stroop task and the Mood Regulation Scales were used. The results showed no significant differences in RTs to emotional and neutral words. Unexpectedly, a speeding effect was observed with the age of women. It appeared also that the effect of mood regulation tendencies was not significant for RTs. The last two effects are not consistent with the literature on cognitive and emotional aging.

Opis:
Sformułowano hipotezę, że uwagę postmedytacyjną osób, które osiągnęły wprawę w medytowaniu, cechuje stosunkowo szeroki zakres i "czujność", objawiająca się relatywnie głębokim, semantycznym przetwarzaniem informacji. Dla zweryfikowania tej hipotezy opracowano metodę mierzącą jednocześnie 1. Zakres uwagi (centrum vs. peryferia) 2. Poziom przetwarzania informacji (płytki - zmysłowy vs. głęboki - semantyczny). Konstrukcję metody oparto na zadaniu Stroopa (1935) oraz na zadaniu DIVA (Nęcka, 1994). Badano stany uwagi intensywnej (po czytaniu tekstu), ekstensywnej (po relaksacji) i post medytacyjnej (po medytacji Zen). Grupy kontrolne (relaksowana i skoncentrowana zadaniowo) różniły się istotnie na badanych wymiarach. Szerszy zakres uwagi cechował osoby zrelaksowane (z uwagą ekstensywną) i u nich także zaobserwowano zniesienie efektu Stroopa na skutek płytszego, zmysłowego przetwarzania informacji. Uwagę postmedytacyjną charakteryzował szerszy zakres w porównaniu z uwagą osób skoncentrowanych, ale mniejszy niż osób zrelaksowanych. Natomiast tak samo silne interferencje Stroopa z centrum i peryferii osób medytujących wskazują na stabilne, odzmysłowe i wolne od hamowania reakcje na bodźce niespójne. Wyniki poddajemy dyskusji z odniesieniem do badań neuropsychologicznych.

Opis:
This study examined cognitive predictors of susceptibility to orientation illusions: Poggendorff, Ponzo, and Zöllner. It was assumed that lower efficiency of information processing in WM and higher field dependence are conducive to orientation illusions. 61 architects (30 women) aged M = 29, +/- 1.6, and 49 university students (29 women) aged M = 23.53, +/- 4.24, were tested with Witkin’s EFT to assess their field dependence; the SWATT method was used as a measure of WM efficiency, and susceptibility to visual illusions was verified with a series of computer tasks. We obtained a small range of the explained variance in the regression models including FDI and WM indicators. On the basis of WM efficiency indicators, we managed to confirm the existence of memory predictors of susceptibility to illusions (they are rather weak, as they explain from 6% to 14% of the variance of the dependent variable). Among the architects, lower efficiency of WM processing (weaker inhibition, task-switching) and higher field dependence are responsible for greater susceptibility to orientation illusions.

Opis:
The main hypothesis of studies presented in this article is that episodic implicit evaluations (affects) toward task-relevant objects determine thinking and decisions by actively placing them within or outside the scope of attention. In these studies we also aimed to test the impact of regulatory focus on implicit evaluations and goal pursuit. We applied the Promotion-Prevention Self-control Scale as a measure of mind-set during thinking in the Wason Selection Task (WST) in Study 1 and Island Decision Game (IDG) in Study 2. Directly after learning of the tasks, participants evaluated (in affective priming paradigm) objects that constituted the task’s content. The findings are in line with the hypothesis stating that goals influence the way in which objects are automatically evaluated. The effects of promotion mind-set were more pronounced in both studies. Promotion-focused individuals positively assessed objects that serve as a confirmation. The implicit evaluations by prevention-oriented individuals disclosed their falsifying approach to the WST. The positive implicit evaluation of correct objects suggests their sensitivity to information useful for falsification and is consistent with their tendency to cautiously self-control thinking.

Opis:
The aim of the study was to confi rm the mediation effects of the task-specifi c self-effi cacy on the relationship between the general self-effi cacy and intention and planning considering treatment. The study comprised 265 subjects, of which 165 were post-mastectomy women and 100 patients hospitalized due to acute coronary syndrome (ACS). The variables were assessed using the Generalized Self-Effi cacy Scale (GSES) and tools developed to examine the context of treatment. The data were analyzed using the bootstrapping procedure. The results confi rmed the indirect effects of task-specifi c self-effi cacy, both in women making a decision to undergo breast reconstruction, and in patients after ACS formulating intention to change risk behaviours. As smoking was considered to be a moderator in the post-ACS group, the obtained associations were observed only among the patients declaring quitting smoking. In view of the fact that taskspecifi c self-effi cacy is susceptible to context (e.g. it may depend on quitting smoking), it is useful to assess it in order to increase treatment effectiveness.

In this paper, a stabilizer dedicated for a unicycle-like robot is considered. The proposed smooth control law ensures the global boundedness of position and orientation trajectories to a neighbourhood of the desired point with an arbitrarily selected radius and it is robust to bounded additive measurement noises. The controller consists of a smooth hybrid navigation algorithm and a smooth feedback based on the transverse function approach. The stability proof, simulation and experimental results illustrating properties of the algorithm are discussed.

The paper presents a detailed theoretical background for coordinate measurement uncertainty evaluation by means of Type B evaluation method, taking into account information on accuracy of a coordinate measuring system given with the formula for maximum permissible errors of length measurement and verification test results. A proposal for evaluation of the verification test results is made. A measurement model based on the point-plane distance equation is presented. A detailed analysis of the partial derivatives (sensitivity factors in an uncertainty budget) of the measurement model is presented. The analyses of measurement uncertainty for different geometrical characteristics were conducted using this measurement model. Examples of uncertainty evaluation for geometrical deviations are presented: position of a point related to a datum plane and flatness in the case of convex or concave surfaces. The examples include detailed uncertainty budgets.
