In this paper, we present a new questionnaire for the assessment of self-control as an individual trait. We describe the process of construction of this assessment tool. We also report the results of relevant validation studies. The questionnaire has two independent versions, one based on self-reports and another one based on other-reports. The first version consists of five subscales, called Initiative and Persistence, Proactive Control, Switching and Flexibility, Inhibition and Adjournment, and Goal Maintenance. Seven samples of participants took part in (...) the validation study. The second version has not been split into subscales. Both versions obtained satisfactory indices of internal consistency, assessed with Cronbach’s alpha. The NAS-50 and NAS-40 scores were highly correlated with other measures of self-control, including Tangney, Baumeister, and Boone’s self-control scale. They also proved to be entirely independent of general intelligence. In conclusion, both versions can be regarded reliable and valid enough, and therefore suitable for the assessment of trait self-control for research purposes. (shrink)

Short-term memory search, as investigated within the Sternberg paradigm, is usually described as exhaustive rather than self-terminated, although the debate concerning these issues is still hot. We report three experiments employing a modified Sternberg paradigm and show that whether STM search is exhaustive or self-terminated depends on task conditions. Specifically, STM search self-terminates as soon as a positive match is found, whereas exhaustive search occurs when the STM content does not contain a searched item. Additionally, we show that task conditions (...) influence whether familiarity- or recollection-based strategies dominate STM search performance. Namely, when speeding up the tempo of stimuli presentation increases the task demands, people use familiarity-based retrieval more often, which results in faster but less accurate recognition judgments. We conclude that STM search processes flexibly adapt to current task conditions and finally propose two-phase model of STM search. (shrink)

Individual differences in decisiveness: pre-decisional information search and decision strategy use We investigated whether individual differences in decisiveness are associated with a tendency to use different decision strategies during pre-decisional information search. To explore these potential links we administered the Need for Cognitive Closure questionnaire to 62 participants, followed by a probabilistic inference, multi-attribute choice task. Participants high in decisiveness dimension, compared to ‘low decisives’, spent less time and acquired less information prior to making decisions, especially in the first trials (...) of the choice task. ‘High decisives’ also had a greater tendency to use a simple Lexicographic heuristic than ‘low decisives’. The results support the view that high decisiveness is associated with greater tendency to simplify the decision process. (shrink)

Cognitive and temperamental predictors of field dependence-independence The purpose of the study was to define structures of connections between the temperamental and cognitive factors as predictors of field dependence-independence. It was assumed that both the structure of temperament traits and cognitive mechanisms manifest themselves in tasks used for measuring cognitive styles. 108 participants took part in the experiment. Embedded Figure Test was used as a measure of field dependence-independence; Formal of Characteristics of Behaviour Temperament Inventory /fcb-ti/ for temperament structure, and (...) three computerized tasks as indicators of wide spectrum of attention and working memory functioning. Three hypothetical models in path analysis were verified. The best fit of the results obtained is provided by the model comprising two groups of factors: two energetic temperamental factors: endurance and emotional reactivity, and two cognitive factors: efficiency of selective attention and efficiency of visual-spatial sketch pad. The data was discussed from temperamental, cognitive and developmental perspectives. (shrink)

In this study bibliometric mapping method was employed to visualise the current research trends and the impact of the two most influential models of working memory, namely: A. D. Baddeley and G. J. Hitch’s multicomponent working memory model and N. Cowan’s embedded-processes model of working memory. Using VOSviewer software two maps were generated based on the index-term words extracted from the research papers citing Baddeley and Cowan, respectively. The maps represent networks of co-occurrences of index terms and can be interpreted (...) as an indication of the main research fields related to the examined models of WM. The results of the analysis revealed that the spheres of influence of the two main conceptualisations of WM are rather different than similar. Although the first two clusters, i.e. “brain mapping” and “higher-level cognition and development” are present in both maps, their relative importance varies. The remaining clusters are unique to each map. Baddeley’s theory seems to have a greater influence on “neuropsychology”, while Cowan’s theory - on basic research on “biological systems”, including the nervous system in humans and animals. The second difference between these theories concerns their relations to functions and dysfunctions associated with particular sensory modalities: in Baddelay’s theory with the “auditory modality” cluster, and in Cowan’s - with the “visual modality” one.
