Despite extensive research on the cognitive basis for mathematical activity, the associations between long-term memory and math skills remain relatively understudied. In our fuzzy-trace theory-driven study, we addressed this issue by investigating the relationships between long-term memory for numbers and prominent math skills, namely approximate n...

Developmental dyscalculia is a learning disorder leading to numerical skills deficits. The current research trend, seeking for causes of dyscalculia in deficits of domain-general skills rather than a single deficit in number sense, has resulted in multiple studies focused on working memory. Yet, the research on long-term memory in dyscalculia remai...

An effective factor by which false memories can arise is relatedness which includes not only semantic associations but also perceptual resemblance. This issue raises questions about how patterns of perceptual features are represented in memory and how they relate to semantic representations. In five experiments, we investigated the memory processes...

Episodic recollection is defined by the re-experiencing of contextual and target details of a past event. The base-rate dependency hypothesis assumes that the retrieval of one contextual feature from an integrated episodic trace cues the retrieval of another associated feature, and that the more often a particular configuration of features occurs,...

Preference reversal (PR) reveals that preferences over risky bets can be reversed between choices and willingness-to-accept or -pay. To date, neither has literature in gambling situations paid attention to whether the expected value difference between bet pairs affects the likelihood of PR, almost nor has empirical research shed light on whether ep...

Według koncepcji Mariana Mazura, człowiek jest systemem autonomicznym zdolnym do samosterowania. Jedna z podstawowych cech tego systemu – dynamizm charakteru – jest możliwa do wyrażenia za pomocą logarytmu naturalnego z ilorazu starzenia się do współczynnika rozbudowy systemu autonomicznego. Niniejszy artykuł prezentuje Kwestionariusz Dynamizmu Cha...

Introduction The specificity of memory functioning in developmental dyslexia is well known and intensively studied. However, most research has been devoted to working memory, and many uncertain issues about episodic memory remain practically unexplored. Moreover, most studies have investigated memory in children and adolescents—much less research h...

In the article, we present analyses and findings which add precision to the role of intentions and the relation between effects in attributing the intentionality of causing a side effect. Our research supplements and modifies numerous findings regarding the appearance of the so-called Knobe effect. The experiments and analyses show that the very or...

Objective The objective of the presented study was to investigate gender differences in the changes of value systems after a cancer diagnosis. Methods In the study, we used the Polish adaptation of the Rokeach Value Survey and compared within-subject differences in the obtained results from before (retrospective) and after patients' cancer diagnos...

False recognition memory for nonstudied items that share features with targets can be reduced by retrieval monitoring mechanisms. The recall-to-reject process, for example, involves the recollection of information about studied items that disqualifies inconsistent test probes. Monitoring for specific features during retrieval may be enhanced by an...

In two correlational studies, we investigated the relationship between symptoms of mental fatigue connected with the ordinary daily activity of undergraduate students and the performance level in tasks engaging executive and attentional processes. We found that mild or moderate levels of fatigue are associated with only a few impairments in cogniti...

The presented study applies the methods of data mining and prediction models to the subject of memory functioning in developmental dyslexia. This article sets forth the results of an analysis of the decision tree algorithm for the classification of dyslexia/non-dyslexia, based on frequency data from the modified simplified conjoint recognition expe...

The specificity of reading impairment in developmental dyslexia base on difficulties with formal aspects of reading (fluency and accuracy), without problems with reading comprehension. These two aspects of reading skill could be easily connected with two types of memory traces assumed in the fuzzy-trace theory: verbatim and gist traces. In this con...

Artykuł omawia metody eksperymentów pamięciowych, najczęściej stosowanych w ba-daniach opartych o teorię rozmytego śladu. Na początku przedstawiono pokrótce samą teorię. Następnie omówiono poszczególne metody (ich procedurę badawczą, sposoby ana-lizy wyników oraz możliwości i ograniczenia) uporządkowane zgodnie z chronologią po-jawiania się ich w p...

The characteristic asymmetry in ascribing intentionality, known as the Knobe effect, is widely thought to result from the moral evaluation of the side effect. Existing research has focused mostly on elucidating the ordinary meaning of the notion of intentionality, while less effort has been devoted to the moral conditions associated with the analyz...

The aim of this study was to define the processes underlying false recognition memory for orthographically related words by using the simplified conjoint recognition paradigm (Stahl & Klauer, 2009), which is grounded in the fuzzy trace theory. We considered 2 accounts. The first assumes that false memory stems from the perceptual feature overlap be...

Past research has demonstrated that participants with a high working-memory capacity (WMC) are less susceptible to false memory than individuals with a low WMC, especially in conditions using forewarning instructions. This suggests that high WMC individuals can use strategic control to counteract false alarms in a memory test. In this study, we exp...

We examined the role of context memory for false recognition of critical lures and for illusory recollection of context in the Deese/Roediger-McDermott paradigm. In order to manipulate context (colour) memory, we asked the participants to read vs. generate items during the study and we presented items from one list using blocked-or mixed-colour for...

The characteristic asymmetry in the attribution of intentionality in causing side effects, known as the Knobe effect, is considered to be a stable model of human cognition. This article looks at whether the way of thinking and analysing one scenario may affect the other and whether the mutual relationship between the ways in which both scenarios ar...

The presented research was conducted in order to investigate the connections between developmental dyslexia and the functioning of verbatim and gist memory traces—assumed in the fuzzy-trace theory. The participants were 71 high school students (33 with dyslexia and 38 without learning difficulties). The modified procedure and multinomial model of S...

Niniejszy artykuł porusza zagadnienie ryzykownych zachowań młodzieży (z akcentem na nadużywanie alkoholu) w perspektywie procesów poznawczych zakładanych przez teorię rozmytego śladu. Koncepcja ta zakłada istnienie dwóch niezależnych śladów pamięciowych (śladu formy i śladu treści), a także opisuje ich powiązanie z procesami rozumowania – badane mi...

The aim of our investigations is to examine the following thesis: people distinguish situations with different normative qualifications. What does it mean? We would like to prove that there is a specific intuition of normativity which helps people to make a decision, differentiate actions and attitudes. In his famous article Intentional Action and...

This article is a theoretical review of the Fuzzy-Trace Theory (FTT, created by Brainerd and Reyna), which is a cognitive theory of memory based on the empirically examined assumption that our mind creates two parallel and independent memory traces (verbatim and gist traces). This paper is motivated by a lack of literature concerning this subject i...

Previous research has demonstrated that context memory performance decreases as a result of cognitive load. However, the role of specific executive resources availability has not been specified yet. In a dual-task experiment, participants performed three kinds of concurrent task engaging: inhibition, updating, or shifting operations. In comparison...

There is no consistency in the literature concerning the concept of entertainment/amusement. This article presents theoretical conceptualization of this phenomenon (in leisure time studies, media psychology, developmental psychology etc.). The author tries to systemize actual knowledge about the subject, show limitations and misconceptions of the p...
