A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, and irrationality.
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and reactivity.
In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli.
Attentional blink (AB) is a phenomenon that reflects temporal limitations in the ability to deploy visual attention. When people must identify two visual stimuli in quick succession, accuracy for the second stimulus is poor if it occurs within 200 to 500 ms of the first.
Affective neuroscience is the study of how the brain processes emotions. This field combines neuroscience with the psychological study of personality, emotion, and mood. The basis of emotions and what emotions are remains an issue of debate within the field of affective neuroscience.
In psychology, the emotional Stroop task is used as an information-processing approach to assessing emotions. Like the standard Stroop effect, the emotional Stroop test works by examining the response time of the participant to name colors of words presented to them. Unlike the traditional Stroop effect, the words presented either relate to specific emotional states or disorders, or they are neutral. For example, depressed participants will be slower to say the color of depressing words rather than non-depressing words. Non-clinical subjects have also been shown to name the color of an emotional word slower than naming the color of a neutral word. Negative words selected for the emotional Stroop task can be either preselected by researchers or taken from the lived experiences of participants completing the task. Typically, when asked to identify the color of the words presented to them, participants reaction times for negative emotional words is slower than the identification of the color of neutral words. While it has been shown that those in negative moods tend to take longer to respond when presented with negative word stimuli, this is not always the case when participants are presented with words that are positive or more neutral in tone.
Affect, in psychology, is the underlying experience of feeling, emotion, attachment, or mood. It encompasses a wide range of emotional states and can be positive or negative. Affect is a fundamental aspect of human experience and plays a central role in many psychological theories and studies. It can be understood as a combination of three components: emotion, mood, and affectivity. In psychology, the term affect is often used interchangeably with several related terms and concepts, though each term may have slightly different nuances. These terms encompass: emotion, feeling, mood, emotional state, sentiment, affective state, emotional response, affective reactivity, disposition. Researchers and psychologists may employ specific terms based on their focus and the context of their work.
Worrying is the mental distress or agitation resulting from anxiety, usually coming from a place of anticipatory fear (terror) or fear coming from a present threat (horror). With more understanding and acceptance, worry transforms into what is concern, recognizing a future outcome that could be troubling, without necessarily having fear in that outcome.
Attentional bias refers to how a person's perception is affected by selective factors in their attention. Attentional biases may explain an individual's failure to consider alternative possibilities when occupied with an existing train of thought. For example, cigarette smokers have been shown to possess an attentional bias for smoking-related cues around them, due to their brain's altered reward sensitivity. Attentional bias has also been associated with clinically relevant symptoms such as anxiety and depression.
Emotional responsivity is the ability to acknowledge an affective stimuli by exhibiting emotion. It is a sharp change of emotion according to a person's emotional state. Increased emotional responsivity refers to demonstrating more response to a stimulus. Reduced emotional responsivity refers to demonstrating less response to a stimulus. Any response exhibited after exposure to the stimulus, whether it is appropriate or not, would be considered as an emotional response. Although emotional responsivity applies to nonclinical populations, it is more typically associated with individuals with schizophrenia and autism.
Emotion can have a powerful effect on humans and animals. Numerous studies have shown that the most vivid autobiographical memories tend to be of emotional events, which are likely to be recalled more often and with more clarity and detail than neutral events.
The oddball paradigm is an experimental design used within psychology research. The oddball paradigm relies on the brain's sensitivity to rare deviant stimuli presented pseudo-randomly in a series of repeated standard stimuli. The oddball paradigm has a wide selection of stimulus types, including stimuli such as sound duration, frequency, intensity, phonetic features, complex music, or speech sequences. The reaction of the participant to this "oddball" stimulus is recorded.
Attentional retraining is the retraining of automatic attentional processes. The method of retraining varies but has typically employed computerized training programs. The term originally indicated retraining of attention to rehabilitate individuals after a brain injury who had neurological disorders of attention including hemineglect, perseveration, limited attention span, and even ADHD. However, in more recent research and clinical applications attentional retraining has also been applied as a type of cognitive bias modification. In this application, attentional retraining refers to the retraining of automatic attentional biases that have been observed in high levels of anxiety.
Cognitive bias modification (CBM) refers to procedures used in psychology that aim to directly change biases in cognitive processes, such as biased attention toward threat stimuli and biased interpretation of ambiguous stimuli as threatening. The procedures are designed to modify information processing via cognitive tasks that use basic learning principles and repeated practice to encourage a healthier thinking style in line with the training contingency.
Pre-attentive processing is the subconscious accumulation of information from the environment. All available information is pre-attentively processed. Then, the brain filters and processes what is important. Information that has the highest salience or relevance to what a person is thinking about is selected for further and more complete analysis by conscious (attentive) processing. Understanding how pre-attentive processing works is useful in advertising, in education, and for prediction of cognitive ability.
Subliminal stimuli are any sensory stimuli below an individual's threshold for conscious perception, in contrast to supraliminal stimuli.
Emotion perception refers to the capacities and abilities of recognizing and identifying emotions in others, in addition to biological and physiological processes involved. Emotions are typically viewed as having three components: subjective experience, physical changes, and cognitive appraisal; emotion perception is the ability to make accurate decisions about another's subjective experience by interpreting their physical changes through sensory systems responsible for converting these observed changes into mental representations. The ability to perceive emotion is believed to be both innate and subject to environmental influence and is also a critical component in social interactions. How emotion is experienced and interpreted depends on how it is perceived. Likewise, how emotion is perceived is dependent on past experiences and interpretations. Emotion can be accurately perceived in humans. Emotions can be perceived visually, audibly, through smell and also through bodily sensations and this process is believed to be different from the perception of non-emotional material.
The neurocircuitry that underlies executive function processes and emotional and motivational processes are known to be distinct in the brain. However, there are brain regions that show overlap in function between the two cognitive systems. Brain regions that exist in both systems are interesting mainly for studies on how one system affects the other. Examples of such cross-modal functions are emotional regulation strategies such as emotional suppression and emotional reappraisal, the effect of mood on cognitive tasks, and the effect of emotional stimulation of cognitive tasks.
The anti-saccade (AS) task is a way of measuring how well the frontal lobe of the brain can control the reflexive saccade, or eye movement. Saccadic eye movement is primarily controlled by the frontal cortex.
Interpretive bias or interpretation bias is an information-processing bias, the tendency to inappropriately analyze ambiguous stimuli, scenarios and events. One type of interpretive bias is hostile attribution bias, wherein individuals perceive benign or ambiguous behaviors as hostile. For example, a situation in which one friend walks past another without acknowledgement. The individual may interpret this behavior to mean that their friend is angry with them.
