Several previous studies showed transfer effects between language control and domain-general control. The present study investigated whether enhancement of cognitive control previously found after forced language-switching (i.e., limited by external demands such as color cues) can also be seen after voluntary language-switching. Participants comple...

Previous studies have reported fewer social biases in bilinguals compared to monolinguals. However, it is unclear whether this tendency is a by-product of being bilingual or whether it is driven by specific bilingual experiences. This paper investigates the connections between different dimensions of bilingual experience and explicit bias expressio...

The broadband shape of the EEG spectrum, summarized using a 1/ f x function, is thought to reflect the balance between excitation and inhibition in cortical regions (E:I balance). This balance is an important characteristic of neural circuits and could inform studies of aging, as older adults show a relative inhibitory activity deficit. Thus far, n...

The growing importance of research on bilingualism in psychology and neuroscience motivates the need for a psychometric model that can be used to understand and quantify this phenomenon. This research is the first to meet this need. We reanalyzed two data sets (N = 171 and N = 112) from relatively young adult language-unbalanced bilinguals and aske...

Evidence for the relationship between individual alpha frequency (IAF) and cognitive ability (general intelligence) is inconclusive, and the role of alpha rhythm in shaping cognition is hotly debated. This study aimed to provide more conclusive evidence. EEG was recorded during three resting state sessions, a vigilance session, and a short-term vis...

The multidimensionality of the bilingual experience makes the investigation of bilingualism fascinating but also challenging. Although the literature distinguishes several aspects of bilingualism, the measurement methods and the relationships between these aspects have not been clearly established. In a group of 171 relatively young Polish–English...

The growing importance of research on bilingualism in psychology and neuroscience motivates the need for a unified approach to understanding and quantifying this phenomenon. This study aimed to establish the first psychometric model of bilingualism. To this end, we re-analyzed two datasets (N = 171 and N = 112) from Polish-English bilinguals who co...

This study investigated how natural language use influences inhibition in language-unbalanced bilinguals. We experimentally induced natural patterns of language use (as proposed by the Adaptive Control Hypothesis) and assessed their cognitive after-effects in a group of 32 Polish–English bilinguals. Each participant took part in a series of three l...

According to the Adaptive Control Hypothesis, only intense use of two languages in the same situation (called dual-language context) confers cognitive benefits in response inhibition. To test this hypothesis, we designed an innovative longitudinal study: induced specific patterns of language use experimentally and measured their cognitive after-eff...

Given prior studies that provided inconsistent results, there is an ongoing debate on the issue of whether bilingualism benefits cognitive control. We tested the Adaptive Control Hypothesis, according to which only the intense use of different languages in the same situation without mixing them in single utterances (called dual-language context) co...

Neural complexity is thought to be associated with efficient information processing but the exact nature of this relation remains unclear. Here, the relationship of fluid intelligence (gf) with the resting‐state EEG (rsEEG) complexity over different timescales and different electrodes was investigated. A 6‐min rsEEG blocks of eyes open were analyze...

People often have to resolve many conflicts at the same time in their everyday lives. So far, the mechanisms of conflict resolution when multiple conflicts co-occur are not clear. This study examined the neurocognitive mechanisms of cognitive-control adaptation when two sources of conflict co-occur. To this aim, we measured event-related potentials...

Attentional control as an ability to regulate information processing during goal-directed behavior is critical to many theories of human cognition and thought to predict a large range of everyday behaviors. However, in recent years, failures to reliably assess individual differences in attentional control have sparked a debate concerning whether at...

This study tested whether individual sensitivity to an auditory perceptual cue called amplitude rise time (ART) facilitates novel word learning. Forty adult native speakers of Polish performed a perceptual task testing their sensitivity to ART, learned associations between nonwords and pictures of common objects, and were subsequently tested on the...

Although research on bilingualism has attracted great scientific interest in recent decades, we still do not fully understand how bilinguals' language experience impacts language access and cognitive functioning. Our goal is to demonstrate that being exposed to one language, even for a short time, can influence the ability to use the other language...

The accumulating evidence suggests that prior usage of a second language (L2) leads to processing costs on the subsequent production of a native language (L1). However, it is unclear mechanism underlies this effect. It has been proposed that the L1 cost reflects inhibition of L1 representation acting during L1 production; however, previous studies...

The study aimed to investigate the relationship between the frequency of physical exercise and the ability to control negative emotions in adult women. On the basis of the pre screening, 26 frequently active and 26 infrequently active young adult women (mean age=22.9, and 23, respectively) were invited to participate in the study. We assessed their...

The accumulating evidence suggests that prior usage of a second language (L2) leads to processing costs on the subsequent production of a native language (L1). However, it is unclear what mechanism drives this effect. It has been proposed that the L1 cost reflects active inhibition of L1 representation; however, previous studies exploring this issu...

A prior session of moderate intensity continuous exercise (MCE) benefits performance during tasks requiring conflict resolution but the specific cognitive process that underlies this improvement remains unknown. Many studies postulate that MCE increases inhibition, but ERP evidence is ambiguous due to significant differences across past procedures....

In Kałamała, Szewczyk, Senderecka, and Wodniecka (2018), Figure 5b and 5c contained errors in graph colours. The correct figure is enclosed.

A bilingual advantage in the efficiency of executive control in young adults has been demonstrated in many but not all studies. We aimed to test the efficiency of executive control in a lateralized version of the Attentional Network Task and to investigate accompanying ERP components. The performance of young adult bilinguals who acquired their L2...

Delta-gamma phase-amplitude coupling strongly predicts fluid intelligence

Electrophysiological investigations have pointed out significant yet weak correlations between intelligence and oscillatory brain activity, including the spectral power, frequency, complexity, synchrony, and coherence of electroencephalographic (EEG) signals, however neglecting the interplay between fast and slow neuronal oscillations underlying in...

Examining the mechanism underlying resolution of conflict in the flanker task. Exploration of stimulus-locked ERPs sensitive to manipulation of congruency in the flanker task.

In many published studies, various modifications of the flanker task have been used. Regardless of the flanker task version, the conflict N2 component has been consistently reported and interpreted as evidence for the resolution of conflict introduced by incongruent flankers. However, ERP studies that used the most basic flanker task (i.e., a versi...

Four experiments investigated whether conforming to Gestalt principles, well known to drive visual perception, also facilitates the active maintenance of information in visual working memory (VWM). We used the change detection task, which required the memorization of visual patterns composed of several shapes. We observed no effects of symmetry of...
