Mental training affects distribution of limited brain resources. (1/71)

The information processing capacity of the human mind is limited, as is evidenced by the so-called "attentional-blink" deficit: When two targets (T1 and T2) embedded in a rapid stream of events are presented in close temporal proximity, the second target is often not seen. This deficit is believed to result from competition between the two targets for limited attentional resources. Here we show, using performance in an attentional-blink task and scalp-recorded brain potentials, that meditation, or mental training, affects the distribution of limited brain resources. Three months of intensive mental training resulted in a smaller attentional blink and reduced brain-resource allocation to the first target, as reflected by a smaller T1-elicited P3b, a brain-potential index of resource allocation. Furthermore, those individuals that showed the largest decrease in brain-resource allocation to T1 generally showed the greatest reduction in attentional-blink size. These observations provide novel support for the view that the ability to accurately identify T2 depends upon the efficient deployment of resources to T1. The results also demonstrate that mental training can result in increased control over the distribution of limited brain resources. Our study supports the idea that plasticity in brain and mental function exists throughout life and illustrates the usefulness of systematic mental training in the study of the human mind.  (+info)

Enhanced identification of smoking-related words during the attentional blink in smokers. (2/71)

The attentional blink (AB) occurs when ongoing processing of one target (T1) in a series of rapidly presented stimuli impairs processing of a subsequently presented second target (T2), such that T2 cannot be consciously perceived or reported. There is evidence that the AB can be influenced by the emotional or motivational salience of T2. We examined whether the AB could be attenuated by smoking-related stimuli in smokers. Heavy smokers (N=55) performed an AB task on two occasions, once following 12-h of abstinence and once following ad libitum smoking. T2s were either smoking-related or neutral (household-related) words, and lagged T1 by 0 to 7 distracter words. T1s were all neutral words. Each word was presented for 130 ms. Subjects were required to recall T1 and T2 immediately after each trial. There was a significant word type by lag interaction, whereby smoking-related T2s were recalled better than neutral T2s at early, but not late, lags. The word type effect at early lags was significantly associated with attentional bias assessed on the smoking Stroop task, but was not significantly moderated by abstinence. These data indicate that, in heavy smokers, smoking-related stimuli are more likely to engage conscious awareness than neutral words under conditions of limited attentional resources.  (+info)

Attentional blinks as errors in temporal binding. (3/71)

In the attentional blink [Raymond, J. E., Shapiro, K. L., & Arnell, K. M. (1992). Temporary suppression of visual processing in an RSVP task: An attentional blink? Journal of Experimental Psychology: Human Perception and Performance, 18(3), 849-860.], the second of two targets in a Rapid Serial Visual Presentation (RSVP) stream is difficult to detect and identify when it is presented soon but not immediately after the first target. We varied the Stimulus Onset Asynchrony (SOA) of the items in the stream and the color of the targets (red from gray or vice versa), and looked at the responses to the second target. Exact responses to the second target (zero positional error) showed a typical attentional blink profile, with a drop in performance for an interval of 200-500 ms after the first target. Approximate responses (positional error no greater than 3 frames) showed no such drop in performance, although results were still dependent on color (better for red) and increased with increasing SOA. These findings are consistent with a two-stage model of visual working memory, where encoding of the first target disrupts attention to (and temporal binding of) the second target. We suggest that this disruption occurs within a certain time (approximately 0.5 s) after the first target, during which period salient distractors are as likely as the second target to enter working memory.  (+info)

The blinking spotlight of attention. (4/71)

Increasing evidence suggests that attention can concurrently select multiple locations; yet it is not clear whether this ability relies on continuous allocation of attention to the different targets (a "parallel" strategy) or whether attention switches rapidly between the targets (a periodic "sampling" strategy). Here, we propose a method to distinguish between these two alternatives. The human psychometric function for detection of a single target as a function of its duration can be used to predict the corresponding function for two or more attended targets. Importantly, the predicted curves differ, depending on whether a parallel or sampling strategy is assumed. For a challenging detection task, we found that human performance was best reflected by a sampling model, indicating that multiple items of interest were processed in series at a rate of approximately seven items per second. Surprisingly, the data suggested that attention operated in this periodic regime, even when it was focused on a single target. That is, attention might rely on an intrinsically periodic process.  (+info)

Noradrenergic neuromodulation of human attention for emotional and neutral stimuli. (5/71)

INTRODUCTION: Norepinephrine (NE) has a regulatory role in human attention. OBJECTIVE: To examine its role in emotional modulation of attention, we used an attentional blink (AB) paradigm, in the context of psychopharmacological manipulation, where targets were either emotional or neutral items. RESULTS AND DISCUSSION: We report behavioural evidence that beta-adrenergic blockade with propranolol impairs attention independent of target valence. Furthermore, this effect is centrally mediated as administration of the peripheral beta-adrenergic antagonist nadolol did not impair attention. By contrast, increasing NE tone, using the selective NE reuptake inhibitor reboxetine, improves detection of emotional stimuli. CONCLUSION: In line with theoretical and animal models, these findings provide human behavioural evidence that the adrenergic system has a modulatory influence on selective attention that in some instances depends on item valence.  (+info)

The attentional blink is a phenomenon in visual perception where an individual fails to detect the second of two target stimuli presented in close succession within a rapid serial visual presentation (RSVP) stream of distractors. This occurs because the processing of the first target interferes with the ability to attend to and identify the second target when it appears within approximately 200-500 milliseconds after the first. The attentional blink is thought to reflect limitations in attentional resources and the capacity of working memory.

The refractory period, psychological, is a concept in sexual psychology that refers to the temporary inability of an individual to achieve further sexual arousal or orgasm after experiencing one. It is a normal part of the sexual response cycle and varies from person to person, as well as between different sexual experiences for the same individual.

During the refractory period, the body undergoes a recovery phase where it returns to its pre-aroused state. This period can last from minutes to hours, depending on various factors such as age, overall health, and fatigue level. It is important to note that this concept applies only to psychological aspects of sexual response and does not refer to the refractory period in cardiology or neurology, which refers to the time it takes for a nerve or muscle to respond to a second stimulus after an initial response.

Blinking is the rapid and repetitive closing and reopening of the eyelids. It is a normal physiological process that helps to keep the eyes moist, protected and comfortable by spreading tears over the surface of the eye and removing any foreign particles or irritants that may have accumulated on the eyelid or the conjunctiva (the mucous membrane that covers the front of the eye and lines the inside of the eyelids).

Blinking is controlled by the facial nerve (cranial nerve VII), which sends signals to the muscles that control the movement of the eyelids. On average, people blink about 15-20 times per minute, but this rate can vary depending on factors such as mood, level of attention, and visual tasks. For example, people tend to blink less frequently when they are concentrating on a visual task or looking at a screen, which can lead to dry eye symptoms.

In a medical or psychological context, attention is the cognitive process of selectively concentrating on certain aspects of the environment while ignoring other things. It involves focusing mental resources on specific stimuli, sensory inputs, or internal thoughts while blocking out irrelevant distractions. Attention can be divided into different types, including:

1. Sustained attention: The ability to maintain focus on a task or stimulus over time.
2. Selective attention: The ability to concentrate on relevant stimuli while ignoring irrelevant ones.
3. Divided attention: The capacity to pay attention to multiple tasks or stimuli simultaneously.
4. Alternating attention: The skill of shifting focus between different tasks or stimuli as needed.

Deficits in attention are common symptoms of various neurological and psychiatric conditions, such as ADHD, dementia, depression, and anxiety disorders. Assessment of attention is an essential part of neuropsychological evaluations and can be measured using various tests and tasks.

Serial learning is a form of learning in which new information or skills are acquired and organized in a sequential manner, with each piece of information building on the previous one. In other words, it involves learning items or concepts one at a time, in a specific order, rather than all at once. This type of learning is often used in situations where the material to be learned has a clear sequence, such as learning the alphabet, numbers, or days of the week.

In a medical context, serial learning may be used to teach complex medical procedures or concepts that have multiple steps or components. For example, a medical student may learn how to perform a physical examination by first learning how to take a patient's vital signs, then moving on to inspecting various parts of the body in a specific order. Through repeated practice and reinforcement, the student gradually builds up a sequence of skills and knowledge that becomes integrated into their long-term memory.

It is worth noting that some individuals may find serial learning more challenging than other forms of learning, particularly if they have difficulty with sequential processing or working memory limitations. Therefore, individualized instruction and accommodations may be necessary to support learners who struggle with serial learning tasks.

Visual pattern recognition is the ability to identify and interpret patterns in visual information. In a medical context, it often refers to the process by which healthcare professionals recognize and diagnose medical conditions based on visible signs or symptoms. This can involve recognizing the characteristic appearance of a rash, wound, or other physical feature associated with a particular disease or condition. It may also involve recognizing patterns in medical images such as X-rays, CT scans, or MRIs.

In the field of radiology, for example, visual pattern recognition is a critical skill. Radiologists are trained to recognize the typical appearances of various diseases and conditions in medical images. This allows them to make accurate diagnoses based on the patterns they see. Similarly, dermatologists use visual pattern recognition to identify skin abnormalities and diseases based on the appearance of rashes, lesions, or other skin changes.

Overall, visual pattern recognition is an essential skill in many areas of medicine, allowing healthcare professionals to quickly and accurately diagnose medical conditions based on visible signs and symptoms.

Reaction time, in the context of medicine and physiology, refers to the time period between the presentation of a stimulus and the subsequent initiation of a response. This complex process involves the central nervous system, particularly the brain, which perceives the stimulus, processes it, and then sends signals to the appropriate muscles or glands to react.

There are different types of reaction times, including simple reaction time (responding to a single, expected stimulus) and choice reaction time (choosing an appropriate response from multiple possibilities). These measures can be used in clinical settings to assess various aspects of neurological function, such as cognitive processing speed, motor control, and alertness.

However, it is important to note that reaction times can be influenced by several factors, including age, fatigue, attention, and the use of certain medications or substances.

Photic stimulation is a medical term that refers to the exposure of the eyes to light, specifically repetitive pulses of light, which is used as a method in various research and clinical settings. In neuroscience, it's often used in studies related to vision, circadian rhythms, and brain function.

In a clinical context, photic stimulation is sometimes used in the diagnosis of certain medical conditions such as seizure disorders (like epilepsy). By observing the response of the brain to this light stimulus, doctors can gain valuable insights into the functioning of the brain and the presence of any neurological disorders.

However, it's important to note that photic stimulation should be conducted under the supervision of a trained healthcare professional, as improper use can potentially trigger seizures in individuals who are susceptible to them.

In the context of medicine, "cues" generally refer to specific pieces of information or signals that can help healthcare professionals recognize and respond to a particular situation or condition. These cues can come in various forms, such as:

1. Physical examination findings: For example, a patient's abnormal heart rate or blood pressure reading during a physical exam may serve as a cue for the healthcare professional to investigate further.
2. Patient symptoms: A patient reporting chest pain, shortness of breath, or other concerning symptoms can act as a cue for a healthcare provider to consider potential diagnoses and develop an appropriate treatment plan.
3. Laboratory test results: Abnormal findings on laboratory tests, such as elevated blood glucose levels or abnormal liver function tests, may serve as cues for further evaluation and diagnosis.
4. Medical history information: A patient's medical history can provide valuable cues for healthcare professionals when assessing their current health status. For example, a history of smoking may increase the suspicion for chronic obstructive pulmonary disease (COPD) in a patient presenting with respiratory symptoms.
5. Behavioral or environmental cues: In some cases, behavioral or environmental factors can serve as cues for healthcare professionals to consider potential health risks. For instance, exposure to secondhand smoke or living in an area with high air pollution levels may increase the risk of developing respiratory conditions.

Overall, "cues" in a medical context are essential pieces of information that help healthcare professionals make informed decisions about patient care and treatment.

Visual perception refers to the ability to interpret and organize information that comes from our eyes to recognize and understand what we are seeing. It involves several cognitive processes such as pattern recognition, size estimation, movement detection, and depth perception. Visual perception allows us to identify objects, navigate through space, and interact with our environment. Deficits in visual perception can lead to learning difficulties and disabilities.

Perceptual masking, also known as sensory masking or just masking, is a concept in sensory perception that refers to the interference in the ability to detect or recognize a stimulus (the target) due to the presence of another stimulus (the mask). This phenomenon can occur across different senses, including audition and vision.

In the context of hearing, perceptual masking occurs when one sound (the masker) makes it difficult to hear another sound (the target) because the two sounds are presented simultaneously or in close proximity to each other. The masker can make the target sound less detectable, harder to identify, or even completely inaudible.

There are different types of perceptual masking, including:

1. Simultaneous Masking: When the masker and target sounds occur at the same time.
2. Temporal Masking: When the masker sound precedes or follows the target sound by a short period. This type of masking can be further divided into forward masking (when the masker comes before the target) and backward masking (when the masker comes after the target).
3. Informational Masking: A more complex form of masking that occurs when the listener's cognitive processes, such as attention or memory, are affected by the presence of the masker sound. This type of masking can make it difficult to understand speech in noisy environments, even if the signal-to-noise ratio is favorable.

Perceptual masking has important implications for understanding and addressing hearing difficulties, particularly in situations with background noise or multiple sounds occurring simultaneously.

Psychophysics is not a medical term per se, but rather a subfield of psychology and neuroscience that studies the relationship between physical stimuli and the sensations and perceptions they produce. It involves the quantitative investigation of psychological functions, such as how brightness or loudness is perceived relative to the physical intensity of light or sound.

In medical contexts, psychophysical methods may be used in research or clinical settings to understand how patients with neurological conditions or sensory impairments perceive and respond to different stimuli. This information can inform diagnostic assessments, treatment planning, and rehabilitation strategies.

In a medical context, awareness generally refers to the state of being conscious or cognizant of something. This can include being aware of one's own thoughts, feelings, and experiences, as well as being aware of external events or sensations.

For example, a person who is awake and alert is said to have full awareness, while someone who is in a coma or under general anesthesia may be described as having reduced or absent awareness. Similarly, a person with dementia or Alzheimer's disease may have impaired awareness of their surroundings or of their own memory and cognitive abilities.

In some cases, awareness may also refer to the process of becoming informed or educated about a particular health condition or medical treatment. For example, a patient may be encouraged to increase their awareness of heart disease risk factors or of the potential side effects of a medication. Overall, awareness involves a deep understanding and perception of oneself and one's environment.

Ocular fixation is a term used in ophthalmology and optometry to refer to the ability of the eyes to maintain steady gaze or visual focus on an object. It involves the coordinated movement of the extraocular muscles that control eye movements, allowing for clear and stable vision.

In medical terminology, fixation specifically refers to the state in which the eyes are aligned and focused on a single point in space. This is important for maintaining visual perception and preventing blurring or double vision. Ocular fixation can be affected by various factors such as muscle weakness, nerve damage, or visual processing disorders.

Assessment of ocular fixation is often used in eye examinations to evaluate visual acuity, eye alignment, and muscle function. Abnormalities in fixation may indicate the presence of underlying eye conditions or developmental delays that require further investigation and treatment.

Eyelids are the thin folds of skin that cover and protect the front surface (cornea) of the eye when closed. They are composed of several layers, including the skin, muscle, connective tissue, and a mucous membrane called the conjunctiva. The upper and lower eyelids meet at the outer corner of the eye (lateral canthus) and the inner corner of the eye (medial canthus).

The main function of the eyelids is to protect the eye from foreign particles, light, and trauma. They also help to distribute tears evenly over the surface of the eye through blinking, which helps to keep the eye moist and healthy. Additionally, the eyelids play a role in facial expressions and non-verbal communication.

Short-term memory, also known as primary or active memory, is the system responsible for holding and processing limited amounts of information for brief periods of time, typically on the order of seconds to minutes. It has a capacity of around 7±2 items, as suggested by George Miller's "magic number" theory. Short-term memory allows us to retain and manipulate information temporarily while we are using it, such as remembering a phone number while dialing or following a set of instructions. Information in short-term memory can be maintained through rehearsal, which is the conscious repetition of the information. Over time, if the information is not transferred to long-term memory through consolidation processes, it will be forgotten.

'Task Performance and Analysis' is not a commonly used medical term, but it can be found in the field of rehabilitation medicine and ergonomics. It refers to the process of evaluating and understanding how a specific task is performed, in order to identify any physical or cognitive demands placed on an individual during the performance of that task. This information can then be used to inform the design of interventions, such as workplace modifications or rehabilitation programs, aimed at improving task performance or reducing the risk of injury.

In a medical context, task performance and analysis may be used in the assessment and treatment of individuals with disabilities or injuries, to help them return to work or other activities of daily living. The analysis involves breaking down the task into its component parts, observing and measuring the physical and cognitive demands of each part, and evaluating the individual's ability to perform those demands. Based on this analysis, recommendations may be made for modifications to the task or the environment, training or education, or assistive devices that can help the individual perform the task more safely and efficiently.

Overall, task performance and analysis is a valuable tool in promoting safe and effective task performance, reducing the risk of injury, and improving functional outcomes for individuals with disabilities or injuries.

Psychomotor performance refers to the integration and coordination of mental processes (cognitive functions) with physical movements. It involves the ability to perform complex tasks that require both cognitive skills, such as thinking, remembering, and perceiving, and motor skills, such as gross and fine motor movements. Examples of psychomotor performances include driving a car, playing a musical instrument, or performing surgical procedures.

In a medical context, psychomotor performance is often used to assess an individual's ability to perform activities of daily living (ADLs) and instrumental activities of daily living (IADLs), such as bathing, dressing, cooking, cleaning, and managing medications. Deficits in psychomotor performance can be a sign of neurological or psychiatric disorders, such as dementia, Parkinson's disease, or depression.

Assessment of psychomotor performance may involve tests that measure reaction time, coordination, speed, precision, and accuracy of movements, as well as cognitive functions such as attention, memory, and problem-solving skills. These assessments can help healthcare professionals develop appropriate treatment plans and monitor the progression of diseases or the effectiveness of interventions.

Color perception refers to the ability to detect, recognize, and differentiate various colors and color patterns in the visual field. This complex process involves the functioning of both the eyes and the brain.

The eye's retina contains two types of photoreceptor cells called rods and cones. Rods are more sensitive to light and dark changes and help us see in low-light conditions, but they do not contribute much to color vision. Cones, on the other hand, are responsible for color perception and function best in well-lit conditions.

There are three types of cone cells, each sensitive to a particular range of wavelengths corresponding to blue, green, and red colors. The combination of signals from these three types of cones allows us to perceive a wide spectrum of colors.

The brain then interprets these signals and translates them into the perception of different colors and hues. It is important to note that color perception can be influenced by various factors, including cultural background, personal experiences, and even language. Some individuals may also have deficiencies in color perception due to genetic or acquired conditions, such as color blindness or cataracts.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
