Bimodal emotion congruency is critical to preverbal infants’ abstract rule learning

Extracting general rules from specific examples is important, as we must face the same challenge displayed in various formats. Previous studies have found that bimodal presentation of grammar‐like rules (e.g. ABA) enhanced 5‐month‐olds’ capacity to acquire a rule that infants failed to learn when the rule was presented with visual presentation of the shapes alone (circle‐triangle‐circle) or auditory presentation of the syllables (la‐ba‐la) alone. However, the mechanisms and constraints for this bimodal learning facilitation are still unknown. In this study, we used audio‐visual relation congruency between bimodal stimulation to disentangle possible facilitation sources. We exposed 8‐ to 10‐month‐old infants to an AAB sequence consisting of visual faces with affective expressions and/or auditory voices conveying emotions. Our results showed that infants were able to distinguish the learned AAB rule from other novel rules under bimodal stimulation when the affects in audio and visual stimuli were congruently paired (Experiments 1A and 2A). Infants failed to acquire the same rule when audio‐visual stimuli were incongruently matched (Experiment 2B) and when only the visual (Experiment 1B) or the audio (Experiment 1C) stimuli were presented. Our results highlight that bimodal facilitation in infant rule learning is not only dependent on better statistical probability and redundant sensory information, but also the relational congruency of audio‐visual information.

Lay Understanding of Happiness and the Experience of Well-Being: Are Some Conceptions of Happiness More Beneficial than Others?

The aim of the study was to understand aspects of life that men and women associate with happiness and to explore the connections between these associations and well-being (measured as positive affect, negative affect and life satisfaction) in different periods of life. Participants were 785 people who were asked to list associations that came to mind on hearing the word ‘happiness’. The moderating roles of gender and period of life (adolescence/adulthood, transition/no transition) were analysed. Participants associated happiness mostly with health and relationships. Other categories included knowledge, work, material goods and freedom. Those who associated happiness with work had higher levels of positive affect. Associating happiness with relationships predicted greater life satisfaction, whereas associating it with material goods predicted lower satisfaction. Gender moderated the relationship between associations and positive affect: associating happiness with material goods decreased positive affect among men but no such effect was observed among women; associating happiness with relationships was beneficial for women but unbeneficial for men. Additionally, associations with material goods predicted lower positive affect, especially in times of transition. Associating happiness with knowledge decreased positive affect in adolescents and increased it in adults. Some ways of understanding happiness improved life satisfaction but none were related to negative affect. The relationship between concepts of happiness and positive affect is complex; some concepts are unbeneficial only for some people and during certain periods of life.     

MIND WITHIN MATTER: SCIENCE,THE OCCULT,AND THE (META)PHYSICS OF ETHER AND AKASHA

The intersection between quantum theory, metaphysical spirituality, and Indian‐inspired philosophy has an established place in speculative scientific and alternative religious communities alike. There is one term that has historically bridged these two worlds: “Akasha,” often translated as “ether.” Akasha appears both in metaphysical spiritual contexts, most often in ones influenced by Theosophy, and in the speculative scientific discourse that has historically demonstrated a strong affinity for the brand of monistic metaphysics that Indian‐derived spiritualities tend to foster. This article traces the relationship between these groups with special attention to the role of Indian concepts and terminology. More specifically, it argues that Akasha‐as‐ether comes to operate in a manner that bridges gross matter (of which the individual mind is part and parcel) with the notion of a subtle material and transpersonal mind—a version of panpsychism allowing for a coherent quantum monism.     

The Development and Testing of a New Version of the Cognitive Reflection Test Applying Item Response Theory (IRT)

The cognitive reflection test (CRT) is a short measure of a person's ability to resist intuitive response tendencies and to produce a normatively correct response, which is based on effortful reasoning. Although the CRT is a very popular measure, its psychometric properties have not been extensively investigated. A major limitation of the CRT is the difficulty of the items, which can lead to floor effects in populations other than highly educated adults. The present study aimed at investigating the psychometric properties of the CRT applying item response theory analyses (a two‐parameter logistic model) and at developing a new version of the scale (the CRT‐long), which is appropriate for participants with both lower and higher levels of cognitive reflection. The results demonstrated the good psychometric properties of the original, as well as the new scale. The validity of the new scale was also assessed by measuring correlations with various indicators of intelligence, numeracy, reasoning and decision‐making skills, and thinking dispositions. Moreover, we present evidence for the suitability of the new scale to be used with developmental samples. Finally, by comparing the performance of adolescents and young adults on the CRT and CRT‐long, we report the first investigation into the development of cognitive reflection.

Altered Cortico-Limbic Functional Connectivity During an Empathy Task in Subjects with Post-Traumatic Stress Disorder

Empathy is a multidimensional construct consisting of cognitive (inferring mental states) and emotional (empathic concern) components. Emotional empathy is severely impaired in individuals affected by Post-Traumatic Stress Disorder (PTSD). Here, we investigated the neural correlates of such an emotional empathy dysfunction to shed light on the neural circuitry responsible for the social and emotional dysfunction in PTSD. We asked a group of PTSD and a group of healthy controls to solve a Multifaceted Empathy Test, measuring both cognitive and emotional empathy, and investigated the functional connectivity of the cortical areas involved in solving the test. The results revealed that, in healthy individuals, increased neural activity in the frontal cortex modulates activity in the insula while subjects perform the emotional empathy task; whereas, in individuals affected by PTSD, increased activity in limbic regions such the insula and the amygdala modulates activity in the frontal cortex while performing the emotional empathy task. These findings suggest that the lack of cortical top-down control of the frontal cortex on the limbic system in PTSD during empathic processing may explain the emotional and social difficulties experienced by individuals suffering from PTSD.
