The effects of classification structure on organized free recall in children

A sorting presentation procedure was used to study the effects of three classification schemes (self-generated, thematic, or taxonomic) on the organized free recall of second and fifth graders. Recall and clustering were significantly higher for subjects who used self-generated organizations than for subjects given the experimenter-prescribed taxonomic classification. The results indicated that memory performance benefitted when the organization of stimulus materials was consonant with children's personal classification structures.     

The foundations of socionics – A review

This paper discusses the foundations of the theory of socionics, including the rationale behind Aušra Augustinavičiūtė’s model of information processing by the human psyche, and the philosophical thought behind the concept of information metabolism elements. Socionics was developed in the former Soviet Union and may be regarded as analogous to the Myers-Briggs Type Indicator typology of personality. The main goal of this paper is to present socionics to the English-speaking community, in order to better take advantage of its explanatory potential in the fields of interpersonal communication and psychological disorders. Reviewed topics include aspects of Jungian analytical psychology and Kępiński’s information metabolism theory, upon which Augustinavičiūtė based her model. After the model is presented, its theoretical implications are briefly discussed.     

Targeting Ontological Security: Information Warfare in the Modern Age

Recent studies have made great strides looking at the implications that the human need for ontological security has for politics and International Relations. However, less attention has been paid to how actors might target this need. While Steele and Mattern both examine the possible manipulation of subjectivity, this article turns to the concept of information warfare (IW) to broaden the view of how, and to what end, this is pursued. Congruently, by elaborating upon how the digitalization of society has increased the potential to influence and manipulate cognition and emotion, OS strengthens current literature on IW. It argues that by covertly perverting the information landscape, IW can alter how events are connected to national narratives, influencing policy by making certain options appear more/less shameful, or it can unravel the bonds of society by polarizing domestic narrative debates, purposely sowing ontological insecurity. This provides a firmer understanding of the strategic implications interference can have generally and of Russia's interference into the 2016 U.S. election specifically. Therefore, by viewing facets of IW as part of a range of tactics employed to manipulate/undermine subjectivity, a more nuanced understanding of interstate relations subsequently emerges.     

Accuracy and performance of the state-based Φ and liveliness measures of information integration

A number of people have suggested that there is a link between information integration and consciousness, and a number of algorithms for calculating information integration have been put forward. The most recent of these is Balduzzi and Tononi’s state-based Φ algorithm, which has factorial dependencies that severely limit the number of neurons that can be analyzed. To address this issue an alternative state-based measure known as liveliness has been developed, which uses the causal relationships between neurons to identify the areas of maximum information integration. This paper outlines the state-based Φ and liveliness algorithms and sets out a number of test networks that were used to compare their accuracy and performance. The results show that liveliness is a reasonable approximation to state-based Φ for some network topologies, and it has a much more scalable performance than state-based Φ.     

Changing commuters’ behavior using rewards: A study of rush-hour avoidance

In a 13-week field study conducted in The Netherlands, participants were provided with daily rewards – monetary and in-kind, in order to encourage them to avoid driving during the morning rush-hour. Participants could earn a reward (money or credits to keep a Smartphone handset), by driving to work earlier or later, by switching to another mode or by teleworking. The collected data, complemented with pre and post measurement surveys, were analyzed using longitudinal techniques and mixed logistic regression. The results assert that the reward is the main extrinsic motivation for discouraging rush-hour driving. The monetary reward exhibits diminishing sensitivity, whereas the Smartphone has endowment qualities. Although the reward influences the motivation to avoid the rush-hour, the choice how to change behavior is influenced by additional factors including education, scheduling, habitual behavior, attitudes, and travel information availability.     

Effects of unit formation on the perception of a changing sound

The effects of subunit formation on adult listeners' ability to notice changes in a continuous spectral gradient of sound were studied. Results of this experiment support the idea that the auditory system processes information differently within a unit, and that this processing does not occur unless the perceptual system detects unit boundaries. In this experiment, silences were inserted into a continuously changing sound to cause the formation of short units. Listeners noticed the change earlier in conditions with silences inserted than in to conditions where the transition was either unbroken or broken by loud noise bursts. Results are discussed in terms of two processes, one that accentuates stimulus properties present at moments of onset and offset, and a second that uses onsets and offsets to signal the beginnings and ends of units and reduces the change perceived within units.     

Risk aversion in information seeking

The information gain model argues that participants select alternatives with a larger expected value of information gain. The present study investigated risk aversion in information seeking to examine whether the expected value always determines information-seeking behaviour. For this investigation, we used a scale method selection task in which participants were required to select one of two scales for weighing coins in order to find an underweight coin. Two experiments showed that participants more frequently selected the alternative that provided information gain without risk, although its expected information gain was smaller. This finding indicates the presence of risk aversion in information seeking, suggesting that information-seeking behaviour is affected by risk associated with obtaining information gain.     

Digit Span and Articulatory Suppression: A Cross-linguistic Comparison

Information Reduction, a performance-enhancing cognitive strategy which develops with practice, is thought to be consciously and abruptly adopted and then applied consistently. Previous investigations used an Alphabet Verification Task where one observation was that not everyone adopts the strategy, but reasons for this are unclear. We demonstrated Information Reduction in three other tasks, confirming that it is not task-specific. Post-testing questionnaires probed verbally expressible knowledge, to gauge conscious awareness of any strategy. Overall, results indicate considerable variation in Information Reduction usage: Some individuals discovered and used the strategy and could verbally express this, others chose not to use it and some appeared to use it without awareness of doing so. Results also indicate that Information Reduction is not consistently applied, suggesting it is less robust than has been proposed. Our results may be better explained by a theory of practice learning which incorporates both data-driven automaticity and top-down controlled processes.
