On simplicity of formulas

Simple formula should contain only few quantifiers. In the paper the methods to estimate quantity and quality of quantifiers needed to express a sentence equivalent to given one.     

Perception of randomness and predicting uncertain events

Using randomly generated sequences of binary events we asked participants to make predictions about the next event. It turned out that while predicting uncertain events, people do not behave unsystematically. Our research identifies four types of relatively consistent strategies for predicting uncertain binary events: a strategy immune to short-run sequential dependencies consisting of the persistent prediction of long-run majority events, hereafter called the long-run momentum strategy; a strategy immune to short-run sequential dependencies consisting of the persistent prediction of long-run minority events, called the long-run contrarian strategy; a strategy sensitive to short-run sequential dependencies consisting of the prediction of short-run majority events, called the short-run momentum strategy; and a strategy sensitive to short-run sequential dependencies consisting of the prediction of short-run minority events, called the short-run contrarian strategy. When the character of events remains unknown, the most common strategy is the short-run momentum strategy. With the increase of a perceived randomness of the situation, people tend more often to use the short-run contrarian strategy. People differ in their general beliefs about the continuation or reversal of a trend in various natural and social processes. Trend believers, when facing sequences of binary events commonly perceived as random, tend to use momentum strategies, whereas those who believe in the trend's reversal tend to use contrarian strategies.     

Noema in the Light of Contradiction,Conflict, and Nonsense: The Noema as Possibly Thinkable Content

The present paper is guided by the belief that Edmund Husserl’s concept of noema can be significantly enriched when considered in light of extreme epistemological instances. These include the phenomena of the absurd and nonsense, but also intentional conflict and cases of consciousness directed to contradictory objects. The paper shows that the noema, when experienced in such a context, exhibits interesting characteristics that are rather difficult to note in other circumstances. The paper consists of five sections. The first interprets and relates concepts from Logical Investigations to those from Ideas I. The second section discloses the noematic ability to assemble senses for which there is no corresponding object. The third section stresses that the noema must, in some instances, be able to comprise two separate structures of senses through which two different objects are meant. In the fourth section, all of these characteristics are shown to be restricted by the concept of nonsense and the laws of meaning-compounding. In this way, the noema is clarified as “possibly thinkable content.” Finally, in Sect. 5, this idea is brought into dialogue with the most significant interpretations of the noema.

Measurement Invariance of Personal Well-Being Index (PWI-8) Across 26 Countries

This report examines the measurement invariance of the Personal Well-being Index with 8 items (PWI-8). University students (N = 5731) from 26 countries completed the measure either through paper and pencil or electronic mode. We examined uni-dimensional structure of PWI and performed a Multi-group CFA to assess the measurement invariance across the 26 countries, using conventional approach and the alignment procedure. The findings provide evidence of configural and partial metric invariance, as well as partial scalar invariance across samples. The findings suggest that PWI-8 can be used to examine correlates of life satisfaction across all included countries, however it is impossible to compare raw scores across countries.     

Event-Related Potential Correlates of Attention to Mediated Message Processing

The aim of this article is to find neural correlates of attention allocated to processing mediated messages. Event-related potentials (ERPs) for auditory distractors were recorded while subjects were engaged in watching a movie telling a short story (audio-video condition) or listening to a radio program describing the same events (audio condition). The amplitudes of the N1 and P3a components for distractors were larger in the audio than in the audio-video condition. The results indicate a stronger orienting response to auditory distractors when listening to the radio than when listening to and watching television. It confirmed predictions of the limited capacity model of motivated mediated message processing (LC4MP), which assumes that the less complex the encoded message, the more attentional resources are left for additional tasks. The largest amplitude of the P3a was observed during the first stage of encoding the message compared to the next stages. P3a amplitude to repeated auditory distractors seems to be a strong indicator of habituation. Results are discussed in the context of LC4MP and perceptual load theory of attention.     

The Set of Fear Inducing Pictures (SFIP): Development and validation in fearful and nonfearful individuals

Emotionally charged pictorial materials are frequently used in phobia research, but no existing standardized picture database is dedicated to the study of different phobias. The present work describes the results of two independent studies through which we sought to develop and validate this type of database—a Set of Fear Inducing Pictures (SFIP). In Study 1, 270 fear-relevant and 130 neutral stimuli were rated for fear, arousal, and valence by four groups of participants; small-animal (N = 34), blood/injection (N = 26), social-fearful (N = 35), and nonfearful participants (N = 22). The results from Study 1 were employed to develop the final version of the SFIP, which includes fear-relevant images of social exposure (N = 40), blood/injection (N = 80), spiders/bugs (N = 80), and angry faces (N = 30), as well as 726 neutral photographs. In Study 2, we aimed to validate the SFIP in a sample of spider, blood/injection, social-fearful, and control individuals (N = 66). The fear-relevant images were rated as being more unpleasant and led to greater fear and arousal in fearful than in nonfearful individuals. The fear images differentiated between the three fear groups in the expected directions. Overall, the present findings provide evidence for the high validity of the SFIP and confirm that the set may be successfully used in phobia research.     

Brain activity patterns induced by interrupting the cognitive processes with online advertising

As a result of the increasing role of online advertising and strong competition among advertisers, intrusive techniques are commonly used to attract web users’ attention. Moreover, since marketing content is usually delivered to the target audience when they are performing typical online tasks, like searching for information or reading online content, its delivery interrupts the web user’s current cognitive process. The question posed by many researchers in the field of online advertising is: how should we measure the influence of interruption of cognitive processes on human behavior and emotional state? Much research has been conducted in this field; however, most of this research has focused on monitoring activity in the simulated environment, or processing declarative responses given by users in prepared questionnaires. In this paper, a more direct real-time approach is taken, and the effect of the interruption on a web user is analyzed directly by studying the activity of his brain. This paper presents the results of an experiment that was conducted to find the brain activity patterns associated with interruptions of the cognitive process by showing internet advertisements during a text-reading task. Three specific aspects were addressed in the experiment: individual patterns, the consistency of these patterns across trials, and the intra-subject correlation of the individual patterns. Two main effects were observed for most subjects: a drop in activity in the frontal and prefrontal cortical areas across all frequency bands, and significant changes in the frontal/prefrontal asymmetry index.
