The effects of state and trait self-focused attention on sexual arousal in sexually functional and dysfunctional women

This study examined the effects of state self-focused attention on sexual arousal and trait self-consciousness on sexual arousal and function in sexually functional (n=16) and dysfunctional (n=16) women. Self-focused attention was induced using a 50% reflectant television screen in one of two counterbalanced sessions during which self-report and physiological sexual responses to erotic films were measured. Self-focused attention significantly decreased vaginal pulse amplitude (VPA) responses among sexually functional but not dysfunctional women, and substantially decreased correlations between self-report and VPA measures of sexual arousal. Self-focused attention did not significantly impact subjective sexual arousal in sexually functional or dysfunctional women. Trait private self-consciousness was positively related to sexual desire, orgasm, compatibility, contentment and sexual satisfaction. Public self-consciousness was correlated with sexual pain. The findings are discussed in terms of Masters and Johnson's [Masters, W. H. & Johnson, V. E. (1970). Human sexual inadequacy. Boston: Little, Brown) concepts of "spectatoring" and "sensate focus."     

Electrophysiological analysis of error monitoring in schizophrenia

In this study, the authors sought to determine whether abnormalities exhibited by schizophrenia patients in event-related potentials associated with self-monitoring--the error-related negativity (ERN) and the correct response negativity (CRN)--persist under conditions that maximize ERN amplitude and to examine relationships between the ERN and behavior in schizophrenia. Participants performed a flanker task under 2 contingencies: one encouraging accuracy and another emphasizing speed. Compared with healthy participants, in schizophrenia patients the ERN was reduced in the accuracy condition, and the CRN was enhanced in the speed condition. The amplitude of a later ERP component, the error positivity, did not differ between groups in either task condition. Reduced self-correction and increased accuracy following errors were associated with larger ERNs in both groups. Thus, ERN generation appears to be abnormal in schizophrenia patients even under conditions demonstrated to maximize ERN amplitude; however, functional characteristics of the ERN appear to be intact.     

Psychological collectivism: a measurement validation and linkage to group member performance

The 3 studies presented here introduce a new measure of the individual-difference form of collectivism. Psychological collectivism is conceptualized as a multidimensional construct with the following 5 facets: preference for in-groups, reliance on in-groups, concern for in-groups, acceptance of in-group norms, and prioritization of in-group goals. Study 1 developed and tested the new measure in a sample of consultants. Study 2 cross-validated the measure using an alumni sample of a Southeastern university, assessing its convergent validity with other collectivism measures. Study 3 linked scores on the measure to 4 dimensions of group member performance (task performance, citizenship behavior, counterproductive behavior, and withdrawal behavior) in a computer software firm and assessed discriminant validity using the Big Five. The results of the studies support the construct validity of the measure and illustrate the potential value of collectivism as a predictor of group member performance.     

The costs of doing two things at once for young and older adults: talking while walking,finger tapping,and ignoring speech or noise

Young and older adults provided language samples in response to questions while walking, finger tapping, and ignoring speech or noise. The language samples were scored on 3 dimensions: fluency, complexity, and content. The hypothesis that working memory limitations affect speech production by older adults was tested by comparing baseline samples with those produced while the participants were performing the concurrent tasks. There were baseline differences: Older adults' speech was less fluent and less complex than young adults' speech. Young adults adopted a different strategy in response to the dual-task demands than older adults: They reduced sentence length and grammatical complexity. In contrast, older adults shifted to a reduced speech rate in the dual-task conditions.     

Gesturing and naming: the use of functional knowledge in object identification

Studies using functional imaging show reliable activation of premotor cortex when observers view manipulable objects. This result has led to the view that knowledge of object function, particularly the actions associated with the typical use of objects, may play a causal role in object identification. To obtain relevant evidence regarding this causal role, we asked subjects to learn gesture-color associations and then attempt to identify objects presented in colors denoting functional gestures that were congruent or incongruent with the objects' use. A strong congruency effect was observed when subjects gestured the use of an object, but not when they named an object. We conclude that our procedure constitutes a sensitive measure of the recruitment and causal role of functional knowledge and that this recruitment is not present during object naming. Preliminary evidence, however, indicates that gestures evoked by the volumetric shape of an object do contribute to object naming.     

Not "just" a coincidence: frontal-striatal interactions in working memory and interval timing

The frontal cortex and basal ganglia play central roles in working memory and in the ability to time brief intervals. We outline recent theoretical and empirical work to suggest that working memory and interval timing rely not only on the same anatomic structures, but also on the same neural representation of a specific stimulus. Specifically, cortical neurons may fire in an oscillatory fashion to form representations of stimuli, and the striatum (a basal ganglia structure) may detect those patterns of cortical firing that occur co-incident to important events. Information about stimulus identity can be extracted from which cortical neurons are involved in the representation, and information about duration can be extracted from their relative phase. The principles derived from these biologically based models also fit well with a family of behaviourally based models that emphasise the importance of time in many working memory phenomena.     

Waiting

Many people have heard of the sacred sound Aum, but do we really understand what it means or what it is? This article answers that question by examining the original text in which the sacred syllable of Aum is introduced. The three letters that make up the sound Aum each represents a corresponding psychological state. Waking, dreaming, and dreamless sleep are the three main states of consciousness explored in the Mā ūkya Upaniad, a small section contained within the larger Hindu text known as the Upaniads. Some of these texts date back to around the second millennium b.c.e. What can these ancient explorations of human consciousness teach us today and how do they relate to modern depth psychology? The shortest of the Upaniads, the Mā ūkya Upaniad, may be said to hold some of the most profound psychological reflections in all of Indian religious philosophy. In addition to these three states of being, the elusive fourth state, known as Turīya, is also explored in relation to the sacred syllable Aum. This article integrates the commentaries of various Indian gurus with a perspective from analytical psychology. The sounds comprising Aum are explored symbolically and in terms of their psychological meaning, and the psychological role and function of spiritual practices, both East and West, are considered.     

Betula: A Prospective Cohort Study on Memory,Health and Aging

This article describes the Betula Study with respect to objectives, design, participants, and assessment instruments for health and cognition. Three waves of data collection have been completed in 5-year intervals since 1988–1990. A fourth wave started in 2003 and will be completed in 2005. An overview of Betula research is presented under the headings of memory and cognition and cognitive neuroscience. Health-related issues and sex differences as well as comparisons between cross-sectional and longitudinal studies are discussed in the first section. The influence of different genes and of some brain abnormalities for memory functioning in adulthood and old age constitute main topics in the second section. New data are presented on the association between blood pressure and dementia. We demonstrated that a demented group of participants had higher levels of systolic blood pressure and pulse pressure than non-dementia controls 10 years before diagnosis. The new fourth wave of data collection will, in addition to enriching the Betula database, permit revisiting and reanalyzing the existing data from new perspectives.     

Not “just” a coincidence: Frontal‐striatal interactions in working memory and interval timing

The frontal cortex and basal ganglia play central roles in working memory and in the ability to time brief intervals. We outline recent theoretical and empirical work to suggest that working memory and interval timing rely not only on the same anatomic structures, but also on the same neural representation of a specific stimulus. Specifically, cortical neurons may fire in an oscillatory fashion to form representations of stimuli, and the striatum (a basal ganglia structure) may detect those patterns of cortical firing that occur co‐incident to important events. Information about stimulus identity can be extracted from which cortical neurons are involved in the representation, and information about duration can be extracted from their relative phase. The principles derived from these biologically based models also fit well with a family of behaviourally based models that emphasise the importance of time in many working memory phenomena.     

Habitual Self‐Control: A Brief Measure of Persistent Goal Pursuit

Habitual self‐control is defined as a trait‐like personal resource factor that facilitates the enactment of difficult intentions. A 14‐item Habitual Self‐Control Questionnaire (HSCQ) was developed to assess this trait. Reliability, factorial validity, and criterion validity were assessed in five undergraduate student subsamples with an overall N of 2224. Internal consistency was .81 across the entire sample, and test–retest reliability was .83 over a one‐month interval. The HSCQ showed a theoretically meaningful pattern in terms of convergent and discriminant validity and criterion validity in predicting a variety of health behaviours that relate to self‐control, including exercise, dieting behaviour, binge eating and weight loss success. Further, the HSCQ contributed uniquely to the prediction of health behaviours beyond alternative self‐control scales. In a longitudinal part of the study, the HSCQ added to the prediction of action plan completion and satisfaction beyond motivation and moderated the relationship between motivation and enactment of action plans as theoretically expected. In sum, the results provided strong evidence for the reliability and validity of the HSCQ and highlighted some theoretically meaningful differences to already existing measures of self‐control. Theoretical implications are discussed. Copyright © 2012 John Wiley & Sons, Ltd.
