Some previous researchers have found that affect can be described in terms of two dimensions (pleasure and arousal), while others have noted three dimensions are needed (pleasure, arousal, and dominance). The competing claims were tested by creating stimuli with factors previously demonstrated to elicit responses of arousal or dominance, asking respondents to rate the stimuli, and contrasting correlations between ratings and the stimulus factors. Under the two-dimensional theory, the planned contrasts should be zero, while under the three-dimensional theory, the planned contrasts should be nonzero. Results supported the three-dimensional model.

How do different categories of nature-related landscape images shape emotional experience?
Int J Psychol
February 2025
The Academy of Education on Arts, Hangzhou Normal University, Hangzhou, China.
The aim of this study was to explore whether and how diverse categories of nature-related landscape images would influence the emotional dimensions of pleasure, arousal and dominance in the process of aesthetic appreciation, as well as to develop a new nature-related image system (NIS). A total of 575 high-quality images across six categories were selected and assessed by 197 students from the dimensions of aesthetic feeling (AF), pleasure, arousal and dominance. The results showed that different categories evoked varying levels of each dimension, and the impact of landscape categories on emotional experiences cannot be overlooked.

Background: High-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) have demonstrated significant potential for enhancing physical and mental health. However, their respective effects on enjoyment and affective responses remain contentious.
Objective: The objective of this meta-analysis is to evaluate and compare the effectiveness of HIIT and MICT on enjoyment and affective responses in overweight or obese people, and to find the most appropriate exercise mode for overweight or obese people.
Slow stroking evokes a more pleasant sensation but similar autonomic nervous system response than rhythmic touching.

Stimulation of C-tactile afferents with gentle slow stroking of the hairy skin, also called affective touch, evokes a pleasant sensation. We intended to describe psychological and tonic physiological changes evoked by slow stroking, as well as associations between pleasantness of skin sensation and physiological changes and trait-like self-reported characteristics (i.e.

Background: Erogenous sensation zones (ESZs) elicit sexual pleasure upon stimulation. General ESZ maps exist, but they do not assess internal areas of the body, differentiate between individual structures, or quantify the importance of individual ESZs to sexual pleasure. Maps of aversive sensation zones (ASZs), or bodily areas individuals dislike having touched during sex, have not been described.

Article Synopsis
- This study explores how different aspects of color perception (like hue, brightness, and saturation) affect emotional responses (such as valence, arousal, and pleasure) using subjective evaluations and EEG recordings.
- Strong positive correlations were found between brightness and valence, and saturation and arousal, with brighter and more arousing colors linked to greater brain activity in areas associated with positive emotion.
- The research suggests consistent patterns in how colors influence emotions and highlights the need for further investigation using more advanced imaging techniques to deepen our understanding of these relationships and their applications in mental health.
