The Revised UCLA Loneliness Scale: Concurrent and Discriminant Validity Evidence

Abstract: The development of an adequate assessment instrument is a necessary prerequisite for social psychological research on loneliness. Two studies provide methodological refinement in the measurement of loneliness. Study 1 presents a revised version of the self-report UCLA (University of California, Los Angeles) Loneliness Scale, designed to counter the possible effects of response bias in the original scale, and reports concurrent validity evidence for the revised measure. Study 2 demonstrates that although loneliness is correlated with measures of negative affect, social risk taking, and affiliative tendencies, it is nonetheless a distinct psychological experience.

Deciding Advantageously Before Knowing the Advantageous Strategy

Abstract: Deciding advantageously in a complex situation is thought to require overt reasoning on declarative knowledge, namely, on facts pertaining to premises, options for action, and outcomes of actions that embody the pertinent previous experience. An alternative possibility was investigated: that overt reasoning is preceded by a nonconscious biasing step that uses neural systems other than those that support declarative knowledge. Normal participants and patients with prefrontal damage and decision-making defects performed a gambling task in which behavioral, psychophysiological, and self-account measures were obtained in parallel. Normals began to choose advantageously before they realized which strategy worked best, whereas prefrontal patients continued to choose disadvantageously even after they knew the correct strategy. Moreover, normals began to generate anticipatory skin conductance responses (SCRs) whenever they pondered a choice that turned out to be risky, before they knew explicitly that it was a risky choice, whereas patients never developed anticipatory SCRs, although some eventually realized which choices were risky. The results suggest that, in normal individuals, nonconscious biases guide behavior before conscious knowledge does. Without the help of such biases, overt knowledge may be insufficient to ensure advantageous behavior.

Emotion, Decision Making and the Orbitofrontal Cortex

Abstract: The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decision making and the influence on it by emotion. The key idea of this hypothesis is that decision making is a process that is influenced by marker signals that arise in bioregulatory processes, including those that express themselves in emotions and feelings. This influence can occur at multiple levels of operation, some of which occur consciously and some of which occur non-consciously. Here we review studies that confirm various predictions from the hypothesis. The orbitofrontal cortex represents one critical structure in a neural system subserving decision making. Decision making is not mediated by the orbitofrontal cortex alone, but arises from large-scale systems that include other cortical and subcortical components. Such structures include the amygdala, the somatosensory/insular cortices and the peripheral nervous system. Here we focus only on the role of the orbitofrontal cortex in decision making and emotional processing, and the relationship between emotion, decision making and other cognitive functions of the frontal lobe, namely working memory.

Relationship of core self-evaluations traits--self-esteem, generalized self-efficacy, locus of control, and emotional stability--with job satisfaction and job performance: a meta-analysis.

Abstract: Recently, Judge, Locke, and Durham (1997) proposed a higher order construct they termed core self-evaluations or, more simply, positive self-concept. According to Judge et al. (1997), this construct is a broad dispositional trait that is indicated by four more specific traits—self-esteem, generalized self-efficacy, locus of control, and emotional stability (low neuroticism). The core selfevaluations construct was originally proposed as a potential explanatory variable in the dispositional source of job satisfaction. Subsequently, Judge and colleagues also have argued that the construct should be related to work motivation and, ultimately, to job performance (Judge, Erez, & Bono, 1998). Investigations of a link between core self-evaluations and job performance, however, are lacking. Despite a lack of studies linking the core self-evaluations factor to job satisfaction and, especially, to job performance, three of the core traits (self-esteem, locus of control, and emotional stability) appear to be the most widely studied personality traits in personality and applied psychology.1 Yet, with the exception of emotional stability and job performance, we have found no metaanalyses of the relationship between any of these traits with either job satisfaction or job performance.2 Thus, the purpose of the present study is to provide a quantitative review of the literature that examines the relationship of the four core self-evaluation traits with job satisfaction and job performance. This study determines whether general relationships exist and, if so, what the magnitudes of these relationships are. In the next section, we provide a brief review of the four traits and discuss the possible relationship of these traits with both job satisfaction and job performance.
