Valence Bond Theory

11.3K
Coordination compounds and complexes exhibit different colors, geometries, and magnetic behavior, depending on the metal atom/ion and ligands from which they are composed. In an attempt to explain the bonding and structure of coordination complexes, Linus Pauling proposed the valence bond theory, or VBT, using the concepts of hybridization and the overlapping of the atomic orbitals. According to VBT, the central metal atom or ion (Lewis acid) hybridizes to provide empty orbitals of suitable...

Role of Affect in Interpersonal Attraction

237
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

The Influence of Affect on Cognition

304
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

229
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...

Summary
This summary is machine-generated.

This study shows that the brain uses the same neural networks to process positive and negative emotions, whether experienced passively or actively. This supports the affective workspace hypothesis for emotion processing.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Affective Science

Background:

  • Affective valence (positive/negative) is fundamental to human experience.
  • Neuroimaging meta-analyses suggest overlapping neural networks encode valence, differing in activity patterns (affective workspace hypothesis).

Purpose of the Study:

  • To investigate the neural encoding of affective valence using functional near-infrared spectroscopy (fNIRS).
  • To test the affective workspace hypothesis by comparing passive and active emotion elicitation.

Main Methods:

  • Utilized fNIRS to monitor hemodynamic activity in fronto-temporal and occipital regions.
  • Employed multivariate decoding techniques to analyze brain activity during passive viewing and active imagination of affective states.
  • Assessed 49 participants exposed to affective images and mental states.

Main Results:

  • High prediction accuracies were achieved for distinguishing positive vs. neutral (89.90% passive, 85.41% active) and negative vs. neutral (91.53% passive, 81.54% active) conditions.
  • Results indicate valence is encoded similarly across passive and active affective experiences.

Conclusions:

  • Findings support the affective workspace hypothesis, demonstrating a shared neural network for valence processing.
  • Valence representation is consistent regardless of whether affective states are passively perceived or actively imagined.
