Cognitive control allows adapting our behaviour to improve performance. A behavioural signature of cognitive control is the Gratton effect. This effect is observed in conflict tasks and indicates smaller congruency effects after incongruent trials than after congruent trials. Metacognitive experience may play a role in this effect: when participants introspect on their conflict experience, the Gratton effect follows the conflict introspection instead of the stimulus congruency (Desender, Van Opstal, & Van den Bussche, 2014)...

BACKGROUND: Introspection into the factors that affect student success at higher education institutions has gained significant momentum in recent years. Teaching and learning has come under the spotlight with quality enhancement and teaching development funding focussing on student support, enhancing the student environment, and enhancing academics as teachers. Included in this are aspects that try to understand the student. An aspect that is not receiving attention is student health, specifically headaches which could impact student success...

Consciousness, the medium of sentient thought, requires integrity of functional networks and their connectivity. In health, they function as a co-operative but mutually exclusive paradigm of introspection versus external awareness subserved via the Default Mode Network and Task Positive State respectively. Higher thinking is segregated according to need, but this relationship is impacted in disorders of consciousness. In delirium, a disturbance of consciousness, the Default Mode Network is pathologically co-activated and functional cortical connectivity is compromised...

The widespread utilization of social media in recent terror attacks in major European cities should raise a "red flag" for the emergency medical response teams. The question arises as to the impact of social media during terror events on the healthcare system. Information was published well before any emergency authority received a distress call or was requested to respond. Photos published at early stages of the attacks, through social media were uncensored, presenting identifiable pictures of victims. Technological advancements of recent years decrease and remove barriers that enable the public to use them as they see fit...

Encounters with new people result in the extraction and storage in memory of both their external features, allowing us to recognize them later, and their internal traits, allowing us to better control our current interactions with them and anticipate our future ones. Just as we extract, encode, store, retrieve and update the representations of others so, too, do we process representations of ourselves. These representations, which rely on declarative memory, may be altered or cease to be accessible in amnesia...

The use of a variety of neuroanatomical techniques has led to a greater understanding of the adverse effects of stress on psychiatric health. One recent advance that has been particularly valuable is the development of resting state functional connectivity (RSFC) in clinical studies. The current study investigates changes in RSFC in F1 adult female rats exposed to the early life chronic social stress (ECSS) of the daily introduction of a novel male intruder to the cage of their F0 mothers while the F1 pups are in the cage...

BACKGROUND: The practice of yoga has a long history as an integrated lifestyle science. Those who have practiced yoga in its full form (including all eight traditional aspects) find that it touches almost every aspect of their inter- and intra-personal lives. Despite this rich history, the West has adopted limited aspects of yoga practice. When understood narrowly as a physical fitness practice, healthful benefits of yoga may be lost, possibly promoting body-consciousness and injury instead...

When searching a crowd, people can detect a target face only by direct fixation and attention. Once the target is found, it is consciously experienced and remembered, but what is the perceptual fate of the fixated nontarget faces? Whereas introspection suggests that one may remember nontargets, previous studies have proposed that almost no memory should be retained. Using a gaze-contingent paradigm, we asked subjects to visually search for a target face within a crowded natural scene and then tested their memory for nontarget faces, as well as their confidence in those memories...

INTRODUCTION: The Test of Memory Malingering (TOMM) and the Word Memory Test (WMT) are both performance validity tests (PVTs) that use a two-alternative forced-choice (2AFC) recognition memory format. Several studies have reported that these tests are susceptible to cognitive impairment and that the WMT is more susceptible than the TOMM. The current study explored components of recognition memory (i.e., conscious recollection and familiarity) underlying the TOMM and WMT to identify factors that make them susceptible and resilient to cognitive impairment...

In the present research, we looked at how positive-constructive daydreaming, guilty-dysphoric daydreaming, and poor attentional control associate with both broad (i.e., openness to experience) and specific (i.e., introspection) personality traits. A second aim was to determine how daydreaming styles were associated with psychological well-being. Across four studies, 1081 undergraduate (studies 1, 2, and 4) and MTurk (study 3) participants completed online questionnaires. A fixed-effect meta-analysis revealed that introspection was a significant predictor of both positive and negative daydreaming styles, but not a consistent predictor of poor attentional control...

Intolerance of Uncertainty (IU) is a key trans-diagnostic personality construct strongly associated with anxiety symptoms. Traditionally, IU is measured through self-report measures that are prone to bias effects due to impression management concerns and introspective difficulties. Moreover, self-report scales are not able to intercept the automatic associations that are assumed to be main determinants of several spontaneous responses (e.g., emotional reactions). In order to overcome these limitations, the Implicit Association Test (IAT) was applied to measure IU, with a particular focus on reliability and criterion validity issues...

Feelings of knowing (FoK) are introspective self-report ratings of the felt likelihood that one will be able to recognize a currently unrecallable memory target. Previous studies have shown that FoKs are influenced by retrieved fragment knowledge related to the target, which is compatible with the accessibility hypothesis that FoK is partly based on currently activated partial knowledge about the memory target. However, previous results have been inconsistent as to whether or not FoKs are influenced by the accuracy of such information...

Investigators have begun to examine the fleeting urges and inclinations that subjects experience when performing tasks involving response interference and working memory. Building on this research, we developed a paradigm in which subjects, after learning to press certain buttons when presented with certain letters, are presented with two action-related letters (the memoranda) but must withhold responding (4 s) until cued to emit the response associated with only one of the two letters. In the Congruent condition, the action corresponds to the cue (e...

Natural languages are rife with words that describe feelings, introspective states, and social constructs (e.g., liberty, persuasion) that cannot be directly observed through the senses. Effective communication demands linguistic competence with such abstract words. In clinical neurological settings, abstract words are especially vulnerable to the effects of stroke and neurodegenerative conditions such as Alzheimer's disease. A parallel literature in cognitive neuroscience suggests that abstract and concrete words are at least partially neuroanatomically dissociable...

Ayahuasca is a decoctum made of admixture plants containing dimethyltryptamine and harmine. For millennia it has been used as a central element of spiritual, religious, initiation, and other - foremost healing - rituals, originally by the indigenous groups of the Amazon basin and later by the mestizo populations of the region. During the last two decades the brew has raised increased scientific and lay interest about its healing potentials within the framework of Western therapeutic settings. The typical ayahuasca effects consist of strong somatic reactions, vivid visions, relived personal memories, cathartic emotions, and insightful, introspective experiences when the emerging mental contents take different context and get deeper perspectives...

One of the main functions of olfaction is to activate approach/avoidance behavior, toward or away from people, foods, or other odor sources. These behaviors are partly automated and therefore poorly accessible via introspection. Explicit tests need therefore be complemented by implicit tests to provide additional insights into the underlying processes of these behaviors. Affective responses to seven food odors plus one control nonodor were assessed in 28 female participants (18-30 years) using explicit tests [pleasantness, intensity, and non-verbal emotional ratings (PrEmo)] as well as implicit tests that reflect dynamic expressive emotional reactions (facial expressions) as well as behavioral-preparation responses (autonomic nervous system responses: heart rate, skin conductance, and skin temperature)...

All human experiences, including mystical and religious ones, are the result of brain functional activity. Thanks to the study of cases of ecstatic epilepsy with structural (MRI) and functional neuroimaging (fMRI, PET, SPECT) and neurophysiological technologies (recording and stimulation with intracranial electrodes), we now have a better knowledge of certain mental states which involve pleasant and affective symptoms and clarity of mind. These ecstatic experiences are thought to be caused by the activation of the anterior insular cortex and some neuronal networks (basically related to mirror neurons and salience) participating in introspection, social cognition, memory, and emotional processes...

The relationship between number and space representation is still one of the most debated topics in studies of mathematical cognition. Here we offer a concise review of two important behavioral effects that have pointed out the use of a spatially left-to-right oriented mental number line (MNL) in healthy participants: the SNARC effect and the attentional SNARC effect (Att-SNARC). Following a brief summary of seminal investigations on the introspective properties of the MNL, we review recent empirical evidence and theories on the functional origin of the SNARC effect, where upon left/right response choices faster reaction times are found for small numbers with left-side responses and for large numbers with right-side responses...
