We provide evidence that a personality trait, aggression, has a first-order effect on group financial decision making. In a laboratory experiment on group portfolio choice, highly aggressive subjects (measured by a standard psychology test) were much more likely to recommend risky investment strategies consistent with their own personal information, regardless of the information received by oth...

The current research examines what types of change are perceived as allowable versus disallowable in the self while still maintaining a sense of personal continuity. We find that overall, improvements are seen as more allowable than worsening or unspecified change, although this difference varies in magnitude based on the centrality of the trait being considered. Additionally, valence interacts...

A growing body of research exploits social media behaviors to gauge psychological characteristics, though trait empathy has received little attention. Because of its intimate link to the ability to relate to others, our research aims to predict participants’ levels of empathy, given their textual and friending behaviors on Facebook. Using Poisson regression, we compared the variance explained i...

Essentially a biometric system is a pattern recognition system which recognizes a user by determining the authenticity of a specific anatomical or behavioral characteristic possessed by the user. With the ever increasing integration of computers and Internet into daily life style, it has become necessary to protect sensitive and personal data. This paper proposes a multimodal biometric system w...

Three theoretical perspectives on cultural universals and differences in the content of self-concepts were tested in individualistic (United States, n = 178; Australia, n = 112) and collectivistic (Mexico, n = 157; Philippines, n = 138) cultures, using three methods of self-concept assessment. Support was found for both trait perspectives and the individual-self-primacy hypothesis. In contrast,...

A biometric is defined as a unique, measurable, biological characteristic or trait for automatically recognizing or verifying the identity of a human being. These days, biometric technologies are typically used to analyze human characteristics for security purposes. In spite of numerous advantages of biometric based personal authentication systems over traditional security systems based on toke...

OBJECTIVES To evaluate whether cue-evoked affective response would moderate the relationship between depression-proneness and smoking years. METHODS Depression-proneness profiles were derived using clinician diagnosed personal and family histories of major depression, recurrent depression, trait-anhedonia, and ruminative coping styles (n=70). Affective distress was produced by idiographic, gu...

Today biometric techniques are based either on passive (e.g. IrisScan, Face) or active methods (e.g. voice and handwriting). In our work we focus on evaluation of the latter. These methods, also described as behavioral Biometric, are characterized by a trait that is learnt and acquired over time. Several approaches for user authentication have been published, but today they have not yet been ev...

We regard internal states of an automaton as emotional states of an individual, its outputs as its actions towards another individual, and a parameter aaecting its state transition as a personal trait. We therefore propose a representation of an individual with emotional states and a certain personality, by a stochastic automaton and a model of a group in which each individual begins conversati...

Three studies demonstrate that mutual facilitation and interference among personal goals are distinct characteristics rather than mutually exclusive opposites and have different functions for psychological well-being and goal pursuit. The three studies vary in design (cross-sectional, short-termlongitudinal) and follow a multimethod approach using questionnaires, diaries, and objective behavior...
