AbstractMost research investigating auditory perception is conducted in controlled laboratory settings, potentially restricting its generalizability to the complex acoustic environment outside the lab. The present study, in contrast, investigated auditory attention with long-term recordings (>6 h) beyond the lab using a fully mobile, smartphone-based ear-centered electroencephalography (EEG) setup with minimal restrictions for participants. Twelve participants completed iterations of two variants of an oddball task where they had to react to target tones and to ignore standard tones. A rapid variant of the task (tones every 2 seconds, 5 minutes total time) was performed seated and with full focus in the morning, around noon and in the afternoon under controlled conditions. A sporadic variant (tones every minute, 160 minutes total time) was performed once in the morning and once in the afternoon while participants followed their normal office day routine. EEG data, behavioural data, and movement data (with a gyroscope) were recorded and analyzed. The expected increased amplitude of the P3 component in response to the target tone was observed for both the rapid and the sporadic oddball. Miss rates were lower and reaction times were faster in the rapid oddball compared to the sporadic one. The movement data indicated that participants spent most of their office day at relative rest. Overall, this study demonstrated that it is feasible to study auditory perception in everyday life with long-term ear-EEG.

AbstractObjectiveConcealable, miniaturized electroencephalo-graphy (‘mini-EEG’) recording devices are crucial enablers towards long-term ambulatory EEG monitoring. However, the resulting miniaturization limits the inter-electrode distance and the scalp area that can be covered by a single device. The concept of wireless EEG sensor networks (WESNs) attempts to overcome this limitation by placing a multitude of these mini-EEG devices at various scalp locations. We investigate whether optimizing the WESN topology can compensate for miniaturization effects in an auditory attention detection (AAD) paradigm.MethodsStarting from standard full-cap high-density EEG data, we emulate several candidate mini-EEG sensor nodes which locally collect EEG data with embedded electrodes separated by short distances. We propose a greedy group-utility based channel selection strategy to select a subset of these candidate nodes, to form a WESN. We compare the AAD performance of this WESN with the performance obtained using long-distance EEG recordings.ResultsThe AAD performance using short-distance EEG measurements is comparable to using an equal number of long-distance EEG measurements if in both cases the optimal electrode positions are selected. A significant increase in performance was found when using nodes with three electrodes over nodes with two electrodes.ConclusionWhen the nodes are optimally placed, WESNs do not significantly suffer from EEG miniaturization effects in the case of AAD.SignificanceWESN-like platforms allow to achieve similar AAD performance as with long-distance EEG recordings, while adhering to the stringent miniaturization constraints for ambulatory EEG. Their applicability in an AAD task is important for the design of neuro-steered auditory prostheses.

In this study, we used a paradigm recently developed ( Thevenot, Fanget, & Fayol, 2007 ) to determine whether 10-year-old children solve simple addition problems by retrieval of the answer from long-term memory or by calculation procedures. Our paradigm is unique in that it does not rely on reaction times or verbal reports, which are known to potentially bias the results, especially in children. Rather, it takes advantage of the fact that calculation procedures degrade the memory traces of the operands, so that it is more difficult to recognize them when they have been involved in the solution of an addition problem by calculation rather than by retrieval. The present study sharpens the current conclusions in the literature and shows that, when the sum of addition problems is up to 10, children mainly use retrieval, but when it is greater than 10, they mainly use calculation procedures.

The Relationship

Abstract. This study aimed to assess whether brain potentials have significant influences on the relationship between aerobic fitness and cognition. Behavioral and electroencephalographic (EEG) data was collected from 48 young adults when performing a Posner task. Higher aerobic fitness is related to faster reaction times (RTs) along with greater P3 amplitude and shorter P3 latency in the valid trials, after controlling for age and body mass index. Moreover, RTs were selectively related to P3 amplitude rather than P3 latency. Specifically, the bootstrap-based mediation model indicates that P3 amplitude mediates the relationship between fitness level and attention performance. Possible explanations regarding the relationships among aerobic fitness, cognitive performance, and brain potentials are discussed.

Perceptual Representations

Two experiments examined repetition priming in the recognition of famous voices. In Experiment 1, reaction times for fame decisions to famous voice samples were shorter than in an unprimed condition, when voices were primed by a different voice sample of the same person having been presented in an earlier phase of the experiment. No effect of voice repetition was observed for non-famous voices. In Experiment 2, it was investigated whether this priming effect is voice-specific or whether it is related to post-perceptual processes in person recognition. Recognizing a famous voice was again primed by having earlier heard a different voice sample of that person. Although an earlier exposure to that person's name did not cause any priming, there was some indication of priming following an earlier exposure to that person's face. Finally, earlier exposure to the identical voice sample (as compared to a different voice sample from the same person) caused a considerable bias towards responding “famous”—i.e. performance benefits for famous but costs for nonfamous voices. The findings suggest that (1) repetition priming invoice recognition primarily involves the activation of perceptual representations of voices, and (2) it is important to determine the conditions in which priming causes bias effects that need to be disentangled from performance benefits.

Personal Assessment

Education is an activity requiring lengthy efforts and perseverance, as well as skills for acquiring information and its creative usage. All this is based on prolonged motivation, directly related to the improvement of the educational development and the consecutive professional realization. Long-term objectives serve as coordinating terms leading to particular goals in the everyday life and thus, behaviour could be rationalized and directed in a longer prospective towards both the past and the future. The aim of the present study is to survey the opinion and personal assessment of the long-term motivation of students from NSA “Vassil Levski”, Sofia and students from Nish, Serbia. The research was conducted from November 2016 to May 2017. It was done among 96 students (45 fourth-year students at NSA and 51 students from the University in Nish). The students had to fill out a test consisting of 10 questions related to their personal assessment of their long-term motivation. The results of the study were processed mathematically and statistically by: variation analysis, relative share, comparative analysis of two independent samples and comparative analysis of the frequency distributions with χ² – the Pearson criterion.According to the generalized conclusions, a higher percentage of the Bulgarian students is directed towards long-term objectives and prospects than the percentage of the Serbian students. Women are more motivated in their long-term development than men but there are not statistically significant differences along all the questions. Athletes’ motivation is higher than the average one for the whole population. We believe, however, that the motivation changes in the course of the studies and we assume it is higher for the students who are about to graduate.

Abstract The constant conflict between decisions leading to immediate pleasurable consequences versus behaviors aiming at long-term social advantages is reviewed here in the framework of the evolutionary systems regulating behavior. The inescapable temporal perspective in decision-making in everyday life is highlighted and integrated with the role of the executive functions in the modulation of subcortical systems. In particular, the representations of the 'non-existent' future in the prefrontal cortical regions and how these representations can bridge theory and practice in everyday life are addressed. Relevant discussions regarding the battle between emotions and reasons in the determination of more complex decisions in the realm of neuroeconomics and in moral issues have been reserved for a second essay.

This article expands on current conceptualizations and applications of precarity by exploring the everyday socio-spatial complexities of migrant squatters living in informal hotels in the center of Buenos Aires, Argentina. Through ethnographic methods, this research investigates squatters’ practices of negotiating access to shared domestic spaces and resources, while experiencing long-term waiting for eviction from their home and potentially from the city center. Employing a cultural geographies approach, this work is concerned with understanding the ways in which precarity is routinely experienced in the micro-spaces of everyday life. Precarity is examined in its temporal and spatial manifestations, with particular emphasis on gendered experiences and home-making practices. Moving through daily spaces and routine situations, I document how precarity is embedded in the mundane tasks of the domestic, and as a result, unevenly impacts women whose traditional roles as mothers and caretakers mean that they are often at the fore of place-making practices and responsibilities.

This introductory chapter discusses how Americans in the nineteenth century pursued the American Dream. It argues that moving the American Dream from the stratosphere in which it is often discussed into the mundane realities of everyday life forces it to be considered differently. The topics of relevance cease to be the long-term trajectory through which protagonists rise from rags to riches and become instead questions about the immediate contexts in which people live. It suggests that what we might call middle-class respectability gets us further than continuing to discuss the American Dream as an ideal or philosophy of life. Middle-class respectability was something that people may have aspired to as an ideal, but it was modeled, learned, and exhibited in practice.
