Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual mental imagery refers to the ability to conjure images in one’s mind’s eye. This allows people to process visual material above and beyond the constraints of a current point-of-view; for example, a person could imagine, using their mind’s eye, how something might look in a different color, or what it would look like if it were made from a different material or rotated and seen from a different perspective. Mental imagery...

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms. Individuals with depression often experience challenges in both their personal and professional...

Alterations in Respiration II

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients. In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres. Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
FAQs
Researchers distinguish internal influences, such as stress, emotion, sleep, and memory, from external influences, including psychotherapy, medication, substance use, sensory stimulation, and social context. This distinction helps psychology examine whether changes in perception, attention, mood, cognition, or consciousness arise from processes within the person or from surrounding conditions, while also clarifying their behavioral consequences.
Altered states occur when neural and cognitive systems modify how information is processed and how responses are organized. Changes in processing can affect what a person notices, how information is interpreted, and how behavior is selected. Studying this relationship connects subjective changes in mental functioning with observable behavioral responses in psychological research.
Stress, emotion, sleep, and memory represent internal processes that can shift mental functioning without an outside intervention. Their influence may appear through changes in attention, mood, perception, cognition, or consciousness. Considering these factors together allows researchers to examine how ordinary psychological processes contribute to changing information processing and behavior.
These external influences offer distinct contexts for examining changes in mental functioning. Psychotherapy and medication are especially relevant to therapeutic change, whereas substance use, sensory stimulation, and social context help researchers investigate how different surroundings or exposures modify processing and behavior. Comparing these contexts also supports attention to possible impairment and associated risks.
Psychologists examine changes in perception, attention, mood, cognition, and level of consciousness, along with related behavioral responses. These outcomes help researchers investigate consciousness and emotion regulation, explore mental health conditions, and determine how psychological interventions are associated with therapeutic change. The focus extends beyond a single symptom to broader information processing and functioning.
Studying mental state alteration helps evaluate whether an intervention is associated with therapeutic change and supports recognition of risks linked to impairment. This perspective is relevant when changes affect cognition, attention, mood, perception, or consciousness, because those domains influence how people process information and respond behaviorally. It therefore connects psychological research with mental health assessment.
