This study explored how domestic cats perform in a horizontal string-pulling task to determine whether they understand this case of physical causality. Fifteen cats were tested on their ability to retrieve an unreachable food treat in three different set-ups: (a) a single baited string, (b) two parallel strings where only one was baited and (c) two crossed strings where only one was baited. All cats succeeded at pulling a single string to obtain a treat, but none consistently chose the correct string when two strings were parallel. When tested with two crossed strings one cat chose the wrong string consistently and all others performed at chance level. There was no evidence that cats understand the function of the strings or their physical causality.

Life expectancy is constantly increasing in the developed countries due to medical, hygiene and socioeconomic advances. Unfortunately, a longer life not always corresponds to a healthier life. Indeed, aging is associated with growing risk factors for illness associated with societal conditions (isolation, maltreatment), and neurodegenera-tive diseases. Even normal aging is associated with a cognitive decline that can hinder independence and quality of life of elderly. Thus, one major societal challenge is to build policies that support people of all ages to maintain a maximum health and functional capacity throughout their lives. Meditation could be a promising intervention in contrasting the negative effects of aging. Indeed, it has been shown to enhance cognitive efficiency in several domains, such as attention and executive functions in young adults. Nevertheless, whether these effects extend to old participants is still a matter of debate. Few studies have directly investigated this issue, reporting encouraging results in a large panel of cognitive functions, such as: attention, executive functions and memory. However, a final conclusion about the causal role of meditation and the generalization of these results is made difficult due to several methodological limitations. We propose a roadmap for future studies to pass these limitations with the hope that the present work would contribute to the development of the young research field of meditation in gerontology.

Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performa...

Cognitive scientists typically classify cognitive processes as either controlled or automatic. Whereas controlled processes are slow and effortful, automatic processes are fast and involuntary. Over the past decade, we have propelled a research trajectory investigating how top-down influence in the form of suggestion can allow individuals to modulate the automaticity of cognitive processes. Here we present an overarching array of converging findings that collectively indicate that certain individuals can derail involuntary processes, such as reading, by " unringing " the proverbial bell. We examine replications of these effects from both our own laboratory and independent groups, and extend our Stroop findings to several other well-established automatic paradigms, including the McGurk effect. We thus demonstrate how, in the case of highly suggestible individuals, suggestion seems to wield control over a process that is likely even more automatic than the Stroop effect. Finally, we present findings from two novel experimental paradigms exploring the potential of shifting automaticity in the opposite direction e i.e., transforming, without practice, a controlled task into one that is automatic. Drawing on related evidence from the neuroscience of contemplative practices, we discuss how these findings pave the road to a more scientific understanding of voluntary control and automaticity, and expound on their possible experimental and therapeutic applications.

The two contrasting theoretical approaches to visual perception, the constructivist and the ecological, are briefly presented and illustrated through their analyses of space and size perception. Earlier calls for their reconciliation and unification are reviewed. Neurophysiological, neuropsychological, and psychophysical evidence for the existence of two quite distinct visual systems, the ventral and the dorsal, is presented. These two perceptual systems differ in their functions; the ventral system's central function is that of identification, while the dorsal system is mainly engaged in the visual control of motor behavior. The strong parallels between the ecological approach and the functioning of the dorsal system, and between the constructivist approach and the functioning of the ventral system are noted. It is also shown that the experimental paradigms used by the proponents of these two approaches match the functions of the respective visual systems. A dual-process approa...

Chronic pain conditions are complicated and challenging to live with. Capacity to adjust to such conditions may depend on the ability to self-regulate, that is, the ability to alter thoughts, feelings, and behaviors. Self-regulation appears to rely on executive cognitive functions, and the current review, therefore, sought to draw attention to the impact of self-regulatory capacity and executive functions on chronic pain. Chronic pain conditions present with complex interactions of cognitive, emotional, behavioral, and physiological components for which self-regulatory ability is crucial. The ability to self-regulate varies, and self-regulatory strength appears to be a limited resource that can be fatigued. The many challenges of chronic pain conditions could, therefore, tax self-regulatory strength, leading to self-regulatory deficits. The current review proposes a relationship among pain, self-regulatory capacity, self-regulatory demands, executive functions, and self-regulatory fatigue, suggesting that executive functions and self-regulatory deficits are indeed part of the etiology and maintenance of chronic pain conditions.

Several cross-section and training studies have shown that video game play can improve cognitive functions such as visual attention, cognitive control, visual short-term memory, and general processing speed. Unfortunately the replication of these effects is not always successful, even when using similar cognitive tests to measure performance. We investigated an important aspect of this field that has not yet been empirically addressed: the role of video game genre. Our comparison of two video game player groups of specific genres (first-person shooter and real-time strategy) indicates that cognitive abilities (measured by task switching and multiple object tracking) may be differentially enhanced depending on the genre of video game being played. This result is significant as research to this point has focused on “action video games”, a loosely defined category that encompasses several video game genres, without controlling for effects potentially stemming from differences in mechanics between these video games. It also provides some evidence for the specificity of video game play benefits as a function of actions performed within the game, which is not in line with a generalized “learning to learn” accounting of these enhancements.

This paper addresses the broad question of how work in sociolinguistics should be related to social theory, and in particular the assumptions about cognition that can underpin that relation. A discursive psychological approach to issues of cognition is pressed and illustrated by a reworking of Stubb's review of work on language and cognition. A discursive psychological approach is offered to the topics of racist discourse, courtroom interaction, scientific writing, and sexism. Discursive psychology rejects the approach to 'cognition' as a collection of more or less stable inner entities and processes. Instead the focus is on the way 'mental phenomena' are both constructed and oriented to in people's practices.

This study examines the relationship between a computerized neuropsychological assessment battery, the Automated Neuropsychological Assessment Metrics (ANAM) and a widely used ability measure, Woodcock-Johnson III Tests of Cognitive Ability (WJ-III). Results indicated substantial relationship between the ANAM throughput (accuracy/response time) scores and the WJ-III Cognitive Efficiency cluster. An unexpectedly strong relationship was evident between accuracy scores on the ANAM Logical Reasoning scale and the WJ-III General Intellectual Ability score, purporting to measure the g factor. The findings support the viability of the ANAM as a time- and cost-effective tool for appraisal of cognitive function.

As hundreds of so-called "psychotherapies" have been foisted onto the public, all claiming to treat "mental illness," newer understandings of how the human brain actually works and the processes which drive the formations of mentation that we refer to as "the mind," demand a reassessment of what exactly we are referring to by the term "mental illness" and what kinds of intervention would be feasible in both the prevention of and recovery from cognitive and behavioral disorder. A fundamental process in the formation of an individual's mentation is the associations of experience. These associations not only account for constructive behavior, but can also lead to deleterious or negative behavior, suggesting that some associations are negative and therefore the negative behavior can be remolded through contrasting positive associations; however, to understand what this really means and how it works, we must start at the beginning and define what exactly is this negative behavior that we refer to by the term "mental illness." One of the most important axioms of life so simply but profoundly phrased by Oscar Wilde, is that "the truth is rarely pure and NEVER simple" (emphasis mine). Nothing can ever be explained by simple sound bites – oversimplification is just another word for misrepresentation – so to understand, we must truly engage the subject, and to engage the subject, we must first and foremost clearly define what it is that we are seeking to understand. In this case, it demands that we understand what exactly is mental illness.

Methylphenidate (MPH), a stimulant drug with dopamine and noradrenaline reuptake inhibition properties, is mainly prescribed in attention deficit hyperactivity disorder, is increasingly used by the general population, intending to enhance their cognitive function. In this literature review, we aim to answer whether this is effective. We present a novel way to determine the extent to which MPH enhances cognitive performance in a certain domain. Namely, we quantify this by a percentage that reflects the number of studies showing performance enhancing effects of MPH. To evaluate whether the dose-response relationship follows an inverted-U-shaped curve, MPH effects on cognition are also quantified for low, medium and high doses, respectively. The studies reviewed here show that single doses of MPH improve cognitive performance in the healthy population in the domains of working memory (65% of included studies) and speed of processing (48%), and to a lesser extent may also improve verbal...

The role of morphology in reading aloud was examined measuring naming latencies to pseudowords and words composed of morphemes (roots and derivational suffixes) and corresponding simple pseudowords and words. Three groups of Italian children of different ages and reading abilities, including dyslexic children, as well as one group of adult readers participated in the study. All four groups read faster
