The present study demonstrates how the emotional content of search terms and their eventual results affects the breadth We observed the quantity of results selected by users. In a random sample of queries from the Microsoft LiveSearch search engine, 7,021 queries were evaluated using a dictionary with valence and arousal ratings. The number of search results selected was regressed on the valenc...

Although prominent personality theories postulate orthogonality between traits of positive emotionality (PEM) and negative emotionality (NEM), empirical evidence often demonstrates the opposite indicating a negative relationship. Therefore, it is not surprising that dopaminergic (DA) gene loci have been related to traits of positive and of NEM. The present genetic association study investigates...

This study longitudinally investigated the quality and stability of 64 infants' interactions with their professional caregivers in child care centers at 3 and 6 months of age, i.e., across the first 3 months after they entered child care. It was also examined whether the infants' negative emotionality (as rated by the mother) predicted the quality of the caregiver-infant interaction. The intera...

Understanding the association between personality and depression has implications for elucidating etiology and comorbidity, identifying at-risk individuals, and tailoring treatment. We discuss seven major models that have been proposed to explain the relation between personality and depression, and we review key methodological issues, including study design, the heterogeneity of mood disorders,...

A group of 139 infants was observed at 6 and 12 months. Approach and inhibition were measured via latencies to touch lowand high-intensity objects, directional cardiac response to lowand high-intensity sounds and maternal ratings of positive and fearful emotionality. Inhibition showed considerable increases in all three domains from 6 to 12 months. Also reflecting increases in inhibitory proces...

Selfies are self-portrait photos shared on Social Networks. Previous literature has investigated how personality traits, and specifically narcissism, are associated with selfie-posting behaviors. In this contribution we investigated how selfie-posting behaviors are predicted by the six HEXACO personality traits, controlling for age, gender and sexual orientation. The Kinsey scale, three questio...

This paper investigates the extent to which differences in people’s socio-political attitudes and behaviours are underpinned by individual characteristics. Two groups of volunteers: (a) an Iranian sample that have been resident in UK for less than two years, and (b) a British sample, took part in this study. A series of validated scales was used to examine differences in levels of empathy, theo...

The main personality theories are those of Cloninger (1987), Eysenck (1987), Costa & McCrae (1990) and Watson et al (1994); and the circumflex models of Wiggins (1979) and Kiesler (1982), the latter being a circular arrangement of interpersonal dispositions around the orthogonal dimensions of dominance (v. submission) and nurturance (v. hostility). Broadly, the first four models encompass three...

Although it is well established that Bipolar Disorder (BD) is characterized by excessive positive emotionality, the cognitive and neural processes that underlie such responses are unclear. We addressed this issue by examining the role that an emotion regulatory process called self-distancing plays in two potentially different BD phenotypes-BD with vs. without a history of psychosis-and healthy ...

p t a V arious psychiatric disorders, including depression, anxiety, and other mood disorders, as well as responses to addictive drugs, have been linked to malfunctions of receptors coupled to the cyclic adenosine monophosphate (AMP) second-messenger signaling system and/or malfunction of downstream mediators such as protein kinase A (PKA) and the transcription factor cyclic AMP response elemen...
