The virtual sound source is reproduced through a pair of loudspeakers weighted by vector-based amplitude panning (VBAP). Results show that the average measured MAA at 0° azimuth is 1.1° and the average measured MAA at 90° azimuth is 3.1° in a virtual acoustic system, meanwhile the average measured MAA at 0° azimuth is about 1.2° and the average measured MAA at 90° azimuth is 3.3° when using the real sound sources. The measurements of the two methods have no significant difference. We conclude that the proposed MAA test system is a suitable alternative to more complicated and expensive setups.In recent literature, many researchers have highlighted that the feeling of loneliness can be considered a sign of relevant distress with short- and long-term consequences on the health of people who needs to be appropriately monitored and treated. I191 In this view, the Interpersonal Acceptance-Rejection Loneliness Scale (IPARLS) has been developed to evaluate the subjective feelings and distress related to interpersonal loneliness and to overcome the limits of the previous scales; however, its psychometric characteristics have not yet been fully investigated. Starting from these considerations, two studies have been conducted. The first study, involving 688 adults (19-69 years; 51% females), assessed dimensionality, reliability, and validity of and tested the measurement invariance (MI) of the Italian version of the IPARLS. The second study, involving 205 adults (20-69 years; 51% females), investigated the relationship between loneliness and psychological adjustment. Results confirmed the unidimensionality of the scale and showed that it is reliable, valid, and fully invariant as a function of age and gender. Moreover, data showed a strong association between perceived loneliness and psychological adjustment. The IPARLS is confirmed to be a valid and reliable measure to investigate loneliness in the life cycle from clinical and research perspectives.Social learning of vocalizations is integral to song inheritance in oscine passerines. However, other factors, such as genetic inheritance and the developmental environment, can also influence song phenotype. The relative contributions of these factors can have a strong influence on song evolution and may affect important evolutionary processes such as speciation. However, relative contributions are well-described only for a few species and are likely to vary with taxonomy. Using archived song data, we examined patterns of song inheritance in a domestic population of Java sparrows (Lonchura oryzivora), some of which had been cross-fostered. Six-hundred and seventy-six songs from 73 birds were segmented and classified into notes and note subtypes (N = 22,972), for which a range of acoustic features were measured. Overall, we found strong evidence for cultural inheritance of song structure and of the acoustic characteristics of notes; sons' song syntax and note composition were similar to that of their social fathers and were not influenced by genetic relatedness. For vocal consistency of note subtypes, a measure of vocal performance, there was no apparent evidence of social or genetic inheritance, but both age and developmental environment influenced consistency. These findings suggest that high learning fidelity of song material, i.e., song structure and note characteristics, could allow novel variants to be preserved and accumulate over generations, with implications for evolution and conservation. However, differences in vocal performance do not show strong links to cultural inheritance, instead potentially serving as condition dependent signals.Development occurs through the process of setting and working toward goals, in which individuals are often working toward multiple goals that are likely to conflict with one another. Although motivation theories hold that goal conflict is a kind of potential stress that may damage individuals' mental health and wellbeing, the empirical research results on the relationship between goal conflict and wellbeing are quite different. There may be unknown factors affecting the relationship between the two. Against this background, we conducted the exploration of the relationship between goal conflict and life satisfaction, mainly by analyzing the moderated mediating effect of mixed emotions and construal level. The results showed that the goal conflict did not directly affect life satisfaction (β = -0.01, p > 0.5) but indirectly influenced life satisfaction through mixed emotions (β = -0.17, p less then 0.001). The construal level moderated the relationship between mixed emotions and life satisfaction (β = -0.08, p less then 0.01), and the higher construal level will predict higher life satisfaction especially when mixed emotions were low (M - SD) or medium (M). Therefore, the hypothesis of moderated mediating effect is verified, and we can draw the following conclusions (1) Goal conflict does not necessarily impair life satisfaction. (2) Goal conflict impairs life satisfaction conditional on the fact that it triggers mixed emotions. Since mixed emotions are often accompanied by feelings of ambivalence and discomfort, they reduce the individual's evaluation of life satisfaction. (3) In the path of goal conflict reducing life satisfaction through mixed emotions, the higher construal level mitigates the adverse effects of mixed emotions to some extent.The authors examine the too-much-of-a-good-thing effect (TMGT effect) in a model showing that extraversion has a curvilinear relationship with social acceptance and depression. A study of 371 freshmen in a Chinese university showed that extraversion had a curvilinear relationship with social acceptance, such that the relationship was significantly positive from lower to moderate levels of extraversion, but the positive relationship leveled off at higher levels of extraversion. Extraversion also had a curvilinear relationship with depression, such that the relationship was significantly negative from lower to moderate levels of extraversion, but the negative relationship leveled off at higher levels of extraversion. The study indicates that beyond a certain point, the beneficial effects of extraversion on socialization outcomes were diminished. That is, higher levels of extraversion were not associated with more positive socialization outcomes (though they were not associated with worse outcomes either) when extraversion exceeded a certain point.
