Simple Cognitive Task

The aim of the present study is to determine which acoustic components of harmonic consonance and dissonance influence automatic responses in a simple cognitive task. In a series of experiments, ten musical interval pairs were used to measure the influence of acoustic roughness and harmonicity on response times in an affective priming task conducted online. There was a significant correlation between the difference of roughness for each pair of intervals and a response time index. Harmonicity did not influence response times on the cognitive task. More detailed analysis suggests that the presence of priming in intervals is binary: in the negative primes that create congruency effects the intervals’ fundamentals and overtones coincide within the same equivalent rectangular bandwidth (i.e. the minor and major seconds). Intervals that fall outside this equivalent rectangular bandwidth do not elicit priming effects, regardless of their dissonance or cultural conventions of negative affect. The results are discussed in the context of recent developments in consonance/dissonance research and vocal similarity.

Affective Priming Task

Krause et al. (2012) demonstrated that evaluative responses elicited by self-related primes in an affective priming task have incremental validity over explicit self-esteem in predicting self-serving biases in performance estimations and expectations in an anagram task. We conducted a conceptual replication of their experiment in which we added a behavioral and an affective outcome and presented names instead of faces as self-related primes. A heterogeneous sample (N = 96) was recruited for an online data collection. Name primes produced significantly positive and reliable priming effects, which correlated with explicit self-esteem. However, neither these priming effects nor explicit self-esteem predicted the cognitive, affective, or behavioral outcomes. Despite the lack of predictive validity of the implicit measure for affective and behavioral outcomes, the positive and reliable priming effects produced by name primes warrant the further investigation of the validity of the affective priming paradigm as a measure of implicit self-esteem.

Feature Stimulus

A hierarchical dynamical map is proposed as the basic framework for sensory cortical mapping. To show how the hierarchical dynamical map works in cognitive processes, we applied it to a typical cognitive task known as priming, in which cognitive performance is facilitated as a consequence of prior experience. Prior to the priming task, the network memorizes a sensory scene containing multiple objects presented simultaneously using a hierarchical dynamical map. Each object is composed of different sensory features. The hierarchical dynamical map presented here is formed by random itinerancy among limit-cycle attractors into which these objects are encoded. Each limit-cycle attractor contains multiple point attractors into which elemental features belonging to the same object are encoded. When a feature stimulus is presented as a priming cue, the network state is changed from the itinerant state to a limit-cycle attractor relevant to the priming cue. After a short priming period, the network state reverts to the itinerant state. Under application of the test cue, consisting of some feature belonging to the object relevant to the priming cue and fragments of features belonging to others, the network state is changed to a limit-cycle attractor and finally to a point attractor relevant to the target feature. This process is considered as the identification of the target. The model consistently reproduces various observed results for priming processes such as the difference in identification time between cross-modality and within-modality priming tasks, the effect of interval between priming cue and test cue on identification time, the effect of priming duration on the time, and the effect of repetition of the same priming task on neural activity.

The Difference

In performing critical tasks, the reaction time of the decision maker may mean the difference between safety and hazard. While different people have different risk-taking behavior, the process by which they react to a stimulus is fundamentally similar. The process involves perception, decision, and response. Thus, the decision maker sees an outside stimulus, processes the information and arrives at a yes or no decision, and then takes the necessary physical steps to implement the decision. For example, a driver sees the onset of a yellow light, makes up his or her mind about stopping or running for the light, and accordingly steps on the brake or the gas pedal. We refer to perception, decision, and response as the fundamental “triplet” underlying any human performance in a simple or complex environment. Unless this triplet is understood, other behavioral models cannot be constructed with confidence. By observing the percentage of drivers that run for a light and stop for a light, the authors have shown that one can separately measure the perception, decision, and response times in terms of probability distributions. The proposed approach is illustrated for drivers at an intersection through a series of experiments. Preliminary results point to its applicability toward other human tasks, such as landing an aircraft.

We studied the effect of experimenter expectations and different instructions in a balanced placebo design. 157 subjects were randomized into a 2 × 4 factorial design. Two experimenters were led to expect placebos either to produce physiological effects or not (pro- vs. antiplacebo). All subjects except a control group received a caffeine placebo. They were either made to expect coffee, no coffee, or were in a double-blind condition. Dependent measures were blood pressure, heart rate, well-being, and a cognitive task. There was one main effect on the instruction factor (p = 0.03) with the group “told no caffeine” reporting significantly better well-being. There was one main effect on the experimenter factor with subjects instructed by experimenter “proplacebo” having higher systolic blood pressure (p = 0.008). There was one interaction with subjects instructed by experimenter “proplacebo” to receive coffee doing worse in the cognitive task than the rest. Subjects instructed by experimenter “antiplacebo” were significantly less likely to believe the experimental instruction, and that mostly if they had been instructed to receive coffee. Contrary to the literature we could not show an effect of instruction, but there was an effect of experimenters. It is likely, however, that these experimenter effects were not due to experimental manipulations, but to the difference in personalities.

The Difference

The article reflects on the issue of the foreign policy strategy of modern Russia in the Balkans region. One of the most significant aspects of this problem is the difference in views between Russia and the West. Authors show how different interpretations of the events in former Yugoslavia in the 1990s and the beginning of the 2000s predetermined the sense of mutual suspicion and mistrust which spread to other regions such as the post-Soviet space. Exploring differences between the Russian and the Western (Euro-Atlantic) views on the current matters, authors draw attention to fundamental differences in terminology: while the Western narrative promotes more narrow geographical and political definitions (such as the Western Balkan Six), traditional Russian experts are more inclined to wider or integral definitions such as “the Balkans” and “Central and Southeast Europe”. Meanwhile none of these terms are applicable for analysis of the current trends such as the growing transit role of the Balkans region and its embedding in the European regional security architecture. Therefore, a new definition is needed to overcome the differences in vision and better understand significant recent developments in the region. Conceptualizing major foreign policy events in Central and Southeast Europe during the last three decades (the 1990s, 2000s and 2010s), authors demonstrate the significance of differences in tools and methods between the Soviet Union and the modern Russia. Permanent need for adaptation to changing political and security context led to inconsistence in Russian Balkan policy in the 1990s. Nevertheless, Russia was able to preserve an integral vision of the region and even to elaborate new transregional constructive projects, which in right political circumstances may promote stability and become beneficial for both Russia and the Euro-Atlantic community.

Simple Cognitive Task

Abstract Objective This randomised controlled trial (RCT) aimed to investigate the effects of a simple cognitive task intervention on intrusive memories ("flashbacks") and associated symptoms following a traumatic event. Patients presenting to a Swedish emergency department (ED) soon after a traumatic event were randomly allocated (1:1) to the simple cognitive task intervention (memory cue + mental rotation instructions + computer game "Tetris" for at least 20 min) or control (podcast, similar time). We planned follow-ups at one-week, 1-month, and where possible, 3- and 6-months post-trauma. Anticipated enrolment was N = 148. Results The RCT was terminated prematurely after recruiting N = 16 participants. The COVID-19 pandemic prevented recruitment/testing in the ED because: (i) the study required face-to-face contact between participants, psychology researchers, ED staff, and patients, incurring risk of virus transmission; (ii) the host ED site received COVID-19 patients; and (iii) reduced flow of patients otherwise presenting to the ED in non-pandemic conditions (e.g. after trauma). We report on delivery of study procedures, recruitment, treatment adherence, outcome completion (primary outcome: number of intrusive memories during week 5), attrition, and limitations. The information presented and limitations may enable our group and others to learn from this terminated study. Trial registration ClinicalTrials.gov: NCT04185155 (04-12-2019)

New Framework

Following other researchers, we investigated the premise that visual judgment of kinship might be modelled as a signal-detection task, strictly related to similar facial features. We measured subjects' response times to face-pair stimuli while they performed visual judgments of kinship, similarity, or dissimilarity, and examined some priming effects involved. Our results show that kinship judgment takes longer on average than either similarity or dissimilarity judgment—which is compatible with existing models, yet might also suggest that kinship judgments are of a more complex character. In our priming study we observed selective suppression/enhancement of the efficacy of dissimilarity judgments whenever they followed similarity and kinship judgments. This finding confounds the notion, inherent in previous models, of resemblance cues signalling for kinship, since similarity and dissimilarity cannot be considered just as opposite concepts, and observed priming effects need to be explicitly modelled, including dissimilarity cues. To model kinship judgments across faces that are perceived as dissimilar, a new framework may be required, perhaps accepting the perspective of a task-driven use of the visual cues, modulated by experience and cultural conditioning.

The Difference

The activity of ornithine decarboxylase (ODC) is negatively regulated by intracellular polyamines, which thereby mediate a form of feedback inhibition of the initial enzyme in the pathway of their synthesis. This phenomenon has been believed to result, at least in part, from translational regulation. To investigate this further, we performed four series of experiments. First, we found that a chimeric protein encoded by an mRNA containing the ODC 5' leader sequence did not exhibit polyamine-dependent regulation. Second, we showed that transcripts containing the protein-coding sequence of ODC, but no other ODC-derived sequence information, exhibited regulation. Third, we found that the association of ODC mRNA with ribosomes was not altered when intracellular polyamine levels were modulated under conditions previously deemed to cause translational regulation. Last, we carried out experiments to measure the incorporation of [35S]methionine into ODC in polyamine-starved and polyamine-replete cells. Differential incorporation diminished progressively as pulse-label times were shortened; at the shortest labeling time used (4 min), the difference in favor of ODC in polyamine-starved cells was less than twofold. These findings suggest that it is necessary to reevaluate the question of whether polyamines cause alterations of translation of ODC mRNA.
