Past research shows that the bilingual experience may enhance cognitive executive function. In this experiment, we evaluated cognitive control in bilinguals relative to monolinguals by using a dimensional overlap model to predict performance in a task composed of Stroop and Simon stimuli. A group of 24 Spanish monolinguals and 24 bilinguals with differing first languages and all having Spanish as a second language did a picture naming task and a task composed of Stroop and Simon stimuli, where the effect of (...) different overlap conditions between stimuli and responses were examined. The tasks were performed in Spanish for both groups and performance was indexed with behavioral and electrophysiological measures. We hypothesized that the bilinguals’ daily language practice in L2 reflected overlap conditions similar to the Simon task. Both naming a picture in L2 and the Simon task would involve conflict at the response level. L2 picture naming entails interference between two potential oral responses, to name in L2 vs. L1. Similarly, incongruent stimuli in the Simon task produce interference because the irrelevant dimension overlap with an incorrect response. In contrast, the manual Stroop task involves a different type of conflict between two overlapping stimulus dimensions. We predicted for these reasons a superior performance in Simon tasks over Stroop tasks for bilinguals, while monolinguals were expected to have a similar performance in both tasks. We also expected to see a correlation between the performance on the picture naming task and the Simon task in bilinguals. However, the behavioral results did not confirm these hypotheses. In fact, both groups had similar congruency effects as measured by reaction times and error rates, and there was no correlation between the picture naming and Simon task in bilinguals. Despite this, the electrophysiological data suggested a relationship between the picture naming task and the P300 congruency effect in bilinguals. Our findings provide insights into the neurocognitive bases of language and serve as a research avenue for language behaviors in bilinguals. (shrink)

ABSTRACTSolving a conflict between two response options in an interference task has been found to increase control in a subsequent conflict situation. The present research examined whether such conflict adaptation persists in the presence of distractors that have motivational relevance and are therefore competing for attentional resources. In an adjusted flanker task, motivational distractors were presented together with the current trial while the previous trial never included any distractor. Accumulated evidence across three studies showed that motivational distractors reduced the conflict (...) adaptation effect. This was found irrespective of the location at which the distractor occurred, and independent of its valence. Study 3 and a merged data analysis ruled out low-level alternative explanations. In line with a dual competition account (P... (shrink)

Temporal discounting is the tendency to devalue temporally distant rewards. Past studies have examined the k-value, the indifference point, and the area under the curve as dependent measures on this task. The current study included these three measures and a fourth measure, called the interest rate total score. The interest rate total score was based on scoring only those items in which the delayed choice should be preferred given the expected return based on simple interest rates. In addition, associations with (...) several individual difference measures were examined including intelligence, executive functions (inhibition, working memory, and set-shifting), thinking dispositions (Need for Cognition and Consideration of Future Consequences) and engagement in substance use and gambling behavior. A staircase temporal discounting task was examined in a sample of 99 university students. Replicating previous studies, temporal discounting increased with longer delays to reward and decreased with higher reward magnitudes. A hyperbolic function accounted for variance in temporal discounting better than an exponential function. Reaction time at the indifference point was significantly longer than at the other choice points. The four dependent measures of temporal discounting were all significantly correlated and were also significantly associated with our individual difference measures. That is, the tendency to wait for a larger delayed reward on all of the temporal discounting measures was associated with higher intelligence, higher executive functions and more consideration of future consequences. Associations between our measures of temporal discounting and outcomes related to substance use and gambling behavior were modest in our university sample. (shrink)

This study tested the hypothesis that in the minds of adult religious adherents, acquired beliefs about the extraordinary characteristics of God coexist with, rather than replace, an initial representation of God formed by co-option of the evolved person concept. In three experiments, Christian religious adherents were asked to evaluate a series of statements for which core intuitions about persons and acquired Christian beliefs about God were consistent or inconsistent. Participants were less accurate and slower to respond to inconsistent versus consistent (...) statements, suggesting that the core intuitions both coexisted alongside and interfered with the acquired beliefs. In Experiment 2 when responding under time pressure participants were disproportionately more likely to make errors on inconsistent versus consistent statements than when responding with no time pressure, suggesting that the resolution of interference requires cognitive resources the functioning of which decreases under cognitive load. In Experiment 3 a plausible alternative interpretation of these findings was ruled out by demonstrating that the response accuracy and time differences on consistent versus inconsistent statements occur for God—a supernatural religious entity—but not for a natural religious entity.

Neuroarchitecture uses neuroscientific tools to better understand architectural design and its impact on human perception and subjective experience. The form or shape of the built environment is fundamental to architectural design, but not many studies have shown the impact of different forms on the inhabitants’ emotions. This study investigated the neurophysiological correlates of different interior forms on the perceivers’ affective state and the accompanying brain activity. To understand the impact of naturalistic three-dimensional (3D) architectural forms, it is essential to perceive (...) forms from different perspectives. We computed clusters of form features extracted from pictures of residential interiors and constructed exemplary 3D room models based on and representing different formal clusters. To investigate human brain activity during three-dimensional perception of architectural spaces, we used a mobile brain/body imaging (MoBI) approach recording the electroencephalogram (EEG) of participants while they naturally walk through different interior forms in virtual reality (VR). The results revealed a strong impact of curvature geometries on activity in the anterior cingulate cortex (ACC). Theta band activity in ACC correlated with specific feature types (rs (14) = 0.525, p = 0.037) and geometry (rs (14) = - 0.579, p = 0.019), providing evidence for a role of this structure in processing architectural features beyond their emotional impact. The posterior cingulate cortex and the occipital lobe were involved in the perception of different room perspectives during the stroll through the rooms. This study sheds new light on the use of mobile EEG and VR in architectural studies and provides the opportunity to study human brain dynamics in participants that actively explore and realistically experience architectural spaces.

Since Freud and his co-author Breuer spoke of dissociation in 1895, a scientific paradigm was painstakingly established in the field of unconscious cognition. This is the dissociation paradigm. However, recent critical analysis of the many and various reported dissociations reveals their blurred, or unveridical, character. Moreover, we remain ignorant with respect to the ways cognitive phenomena transition from consciousness to an unconscious mode. This hinders us from filling in the puzzle of the unified mind. We conclude that we have reached (...) a Kuhnian crisis in the field of unconscious cognition, and we predict that new models, incorporating partly the relevant findings of the dissociation paradigm—but also of dynamic psychology—, will soon be established. We further predict that some of these models will be largely based on the pairs representation–process and analog–digital. (shrink)

Contemporary studies in unconscious cognition are essentially founded on dissociation, i.e., on how it dissociates with respect to conscious mental processes and representations. This is claimed to be in so many and diverse ways that one is often lost in dissociation. In order to reduce this state of confusion we here carry out two major tasks: based on the central distinction between cognitive processes and representations, we identify and isolate the main dissociation paradigms; we then critically analyze their key tenets (...) and reported findings.

Some stories generate in us a peculiar experience of intense narrative engagement. This common experience, which we call narrative immersion, has been the object of a vast literature in psychology and other disciplines. Philosophers, however, have only recently engaged with this topic and the tendency has been to explain it by postulating specific kinds of mental states. We propose a different approach, explaining narrative immersion by means of a particular distribution of attention over the content of ordinary mental states. First, (...) we provide a characterization of narrative immersion based on studies by psychologists and other theorists. Then, we discuss alternative views and develop our own proposal. We articulate how attention works as we engage with the narrative, and how the adequate distribution of attention over the mental states involved in understanding the storyworld can offer the resources to explain the characteristic features of narrative immersion. Unlike alternative proposals, ours avoids the need to postulate controversial mental states. (shrink)

This article tries to create a bridge of understanding between cognitive scientists and phenomenologists who work on attention. In light of a phenomenology of attention and current psychological and neuropsychological literature on attention, I translate and interpret into phenomenological terms 20 key cognitive science concepts as examined in the laboratory and used in leading journals. As a preface to the lexicon, I outline a phenomenology of attention, especially as a dynamic three-part structure, which I have freely amended from the work (...) of phenomenologist and Gestalt philosopher Aron Gurwitsch (1901–1973). As a conclusion, I discuss the nature of subjectivity in attention and attention research, and whether attention might be the same as consciousness. (shrink)

Number is known for influencing time processing, but to what extent time influences number in human adults is unclear. We investigated possible bidirectional interactions using a novel Stroop-like task; participants compared numbers or temporal durations in congruent or incongruent conditions . Time and number tasks were presented in different blocks or within the same block of trials with task instructions provided at the offset of the stimuli . Analyses of response times and their distribution revealed that number affected time from (...) early RTs, and time affected number at late RTs – an asymmetry observed only when time and number tasks were presented in separate blocks. Thus, carefully chosen tasks and appropriate data analysis can reveal bidirectionality between time and number, consistent with shared magnitude or decision mechanisms. (shrink)

Cognitive scientists distinguish between automatic and controlled mental processes. Automatic processes are either innately involuntary or become automatized through extensive practice. For example, reading words is a purportedly automatic process for proficient readers and the Stroop effect is consequently considered the “gold standard” of automated performance. Although the question of whether it is possible to regain control over an automatic process is mostly unasked, we provide compelling data showing that posthypnotic suggestion reduced and even removed Stroop interference in highly hypnotizable (...) individuals. Drawing on a large sample of highly hypnotizable participants, we examined the effects of suggestion on Stroop performance both with and without a posthypnotic suggestion to perceive the input stream as meaningless symbols. We show that suggestion administered to highly hypnotizable persons significantly reduced Stroop interference and derailed a seemingly automatic process. (shrink)

This paper argues that habits, just like beliefs, can guide intentional action. To do this, a variety of real-life cases where a person acts habitually but contrary to her beliefs are discussed. The cases serve as dissociations showing that intentional agency is possible without doxastic guidance. The upshot is a model for thinking about the rationality of habitual action and the rationalizing role that habits can play in it. The model highlights the role that our history and institutions play in (...) shaping what actions become habitual for us. (shrink)

Although research into the biosemiotic mechanisms underlying the purposeful behavior of brainless living systems is extensive, researchers have not adequately described biosemiosis among neurons. As the conscious use of signs is well-covered by the various fields of semiotics, we focus on subconscious sign action. Subconscious semiotic habits, both functional and dysfunctional, may be created and reinforced in the brain not necessarily in a logical manner and not necessarily through repeated reinforcement. We review literature that suggests hypnosis may be effective in (...) changing subconscious dysfunctional habits, and we offer a biosemiotic framework for understanding these results. If it has been difficult to evaluate any psychological approach, including hypnosis, this may be because contemporary neuroscience lacks a theory of the sign. We argue that understanding the fluid nature of representation in biological organisms is prerequisite to understanding the nature of the subconscious and may lead to more effective of treatments for dysfunctional habits developed through personal experience or culture.

This study investigated the link between meditation, self-reported mindfulness and cognitive flexibility as well as other attentional functions. It compared a group of meditators experienced in mindfulness meditation with a meditation-naïve control group on measures of Stroop interference and the “d2-concentration and endurance test”. Overall the results suggest that attentional performance and cognitive flexibility are positively related to meditation practice and levels of mindfulness. Meditators performed significantly better than non-meditators on all measures of attention. Furthermore, self-reported mindfulness was higher in (...) meditators than non-meditators and correlations with all attention measures were of moderate to high strength. This pattern of results suggests that mindfulness is intimately linked to improvements of attentional functions and cognitive flexibility. The relevance of these findings for mental balance and well-being are discussed. (shrink)

In this study, we investigated whether control of the conflict between incongruent heuristic and analytical answer options in a reasoning task is modulated by the presence of conflict on previous trials. In two experiments, we found that the incongruency of the previous trial has a significant effect on the control exhibited on the current trial. Our data also showed that this adaptation effect is modulated by the incongruency of the previous series of trials. These results demonstrate the same control adaptation (...) effects for a reasoning task as observed for standard response interference tasks. Coinciding control effects in the two research areas suggest that cognitive control might be an important mechanism underlying performance on reasoning tasks. Based on these results we argue that the study of cognitive control in reasoning could potentially facilitate the refinement of empirical predictions and provide a new tool to explore the exertion of top-down control in human thinking.

We make character trait attributions to predict and explain others’ behaviour. How should we understand character trait attribution in context across the domains of philosophy, folk psychology, developmental psychology, and evolutionary psychology? For example, how does trait attribution relate to our ability to attribute mental states to others, to ‘mindread’? This thesis uses philosophical methods and empirical data to argue for character trait attribution as a practice dependent upon our ability to mindread, which develops as a product of natural selection (...) acting on culture instead of genes. This analysis carves out trait attribution’s distinct place within an emerging complex and mature scholarship on pluralistic social cognition. (shrink)

The basis of perception is the processing and categorization of perceptual stimuli from the environment. Much progress has been made in the science of perceptual categorization. Yet there is still no consensus on how the brain generates sensory individuals, from sensory input and perceptual categories in memory. This chapter argues that perceptual categorization is highly variable across perceivers due to their use of different perceptual strategies for solving perceptual problems they encounter, and that the perceptual system structurally adjusts to the (...) strategies that are most successful. Despite this variability, the different sensory individuals that result when different perceivers rely on different strategies nonetheless correspond to actual external world objects/features. This view is called 'perceptual pluralism'. (shrink)

To explore issues of developmental structure, physical em- bodiment, integration of multiple sensory and motor systems, and social interaction, we have constructed an upper-torso humanoid robot called Cog. The robot has twenty-one degrees of freedom and a variety of sen- sory systems, including visual, auditory, vestibular, kinesthetic, and tac- tile senses. This chapter gives a background on the methodology that we have used in our investigations, highlights the research issues that have been raised during this project, and provides a summary (...) of both the current state of the project and our long-term goals. We report on a variety of implemented visual-motor routines (smooth-pursuit track- ing, saccades, binocular vergence, and vestibular-ocular and opto-kinetic re?exes), orientation behaviors, motor control techniques, and social be- haviors (pointing to a visual target, recognizing joint attention through face and eye ?nding, imitation of head nods, and regulating interaction through expressive feedback). We further outline a number of areas for future research that will be necessary to build a complete embodied sys- tem. (shrink)
