The Influence of Cognition on Affect

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be interpreted as...

Negative and Cognitive Symptoms of Schizophrenia

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Psychological and Sociocultural Causes of Schizophrenia

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Cognitive Theories: Schachter-Singer Theory of Emotion

Cognitive Theories: Schachter-Singer Theory of Emotion

Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences physiological...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes loosely...

Schizophrenia

Schizophrenia

Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those diagnosed.

Summary

Negative emotions impair working memory similarly in schizophrenia patients and healthy individuals. Brain imaging reveals distinct neural patterns in patients, suggesting inefficient emotional control impacting cognition.

Area of Science:

Neuroscience
Cognitive Psychology
Psychiatry

Background:

Negative emotions significantly impact cognitive functions.
This interaction is particularly relevant in mental illnesses like schizophrenia, characterized by prevalent negative emotions.
Olfactory emotion induction offers an experimental method to study these effects.

Purpose of the Study:

To investigate the neural correlates of emotion-cognition interactions in schizophrenia patients and healthy volunteers.
To examine how olfactory-induced negative emotions affect working memory performance.
To identify differences in brain activation patterns between patients and controls during this interaction.

Main Methods:

Functional magnetic resonance imaging (fMRI) was used.
Fourteen schizophrenia patients and 14 healthy volunteers participated.
Emotion was induced using odorants during an n-back working memory task.

Main Results:

Both schizophrenia patients and healthy controls showed similar performance decrements in working memory due to negative emotional stimulation.
Patients exhibited decreased activation in the anterior cingulate and medial superior frontal cortex.
Patients showed increased activation in the medial orbitofrontal and middle frontal areas compared to controls.

Conclusions:

Hypoactivations in schizophrenia patients were observed in brain regions critical for process monitoring, control, and emotion regulation.
These decreased activations may indicate an inability to adapt to increased task demands.
Increased activations in patients could reflect heightened emotional responses and irritation, suggesting inefficient control of emotional influences on cognition.
