Psychological characteristics of elderly insomniacs

Sixty insomniacs, aged 60 years or over, fulfilling the DSM-IV criteria for primary insomnia, completed a set of questionnaires measuring psychological distress. These included the Sleep Impairment Index (SIM), the Symptom Check List 90-Revised (SCL-90-R), the Penn State Worry Questionnaire (PSWQ), the Toronto Alexithymia Scale-20 (TAS-20) and the Elders Life Stress Inventory (ELSI). The insomniacs were compared on these measures with two contrast groups, one of elderly good sleepers and one an elderly community sample. As norms were developed for the SCL-90-R and PSWQ, insomniacs were also contrasted with the norm groups on these measures. In general, the results indicated a higher level of psychological distress among insomniacs than among the good sleepers, while there were negligible differences between insomniacs and the community sample on most measures. Overall, elderly insomniacs scored higher on measures of worry compared with the other groups, followed by measures of somatization, obsessive-compulsion and depression. It is concluded that excessive worrying was the most characteristic feature of elderly insomniacs.     

Preparatory processes in the task-switching paradigm: evidence from the use of probability cues

The purpose of the investigations was to dissociate processes of task preparation from task execution in the task-switching paradigm. The basic assumption was that task repetitions have 2 advantages over task shifts: an activation advantage as a result of the execution of the same task type in the pretrial, and an expectation advantage, because participants, in general, implicitly expect a repetition. In Experiments 1-3, the authors explicitly manipulated expectancies by presenting cues that announced a shift and/or a repetition with probabilities of 1.00, .75, .50, or .25. Increasing latencies with decreasing probability for shifts and repetitions show that the expectation advantage can be equalized by preparation. However, the activation advantage represented by constant shift costs between tasks of the same probability is not penetrable by preparation. In Experiments 4 and 5, the authors found evidence that preparation involves activation of the expected task and inhibition of distracting tasks.     

A forced-attention dichotic listening fMRI study on 113 subjects

We report fMRI and behavioral data from 113 subjects on attention and cognitive control using a variant of the classic dichotic listening paradigm with pairwise presentations of consonant-vowel syllables. The syllable stimuli were presented in a block-design while subjects were in the MR scanner. The subjects were instructed to pay attention to and report either the left or right ear stimulus. The hypothesis was that paying attention to the left ear stimulus (FL condition) induces a cognitive conflict, requiring cognitive control processes, not seen when paying attention to the right ear stimulus (FR condition), due to the perceptual salience of the right ear stimulus in a dichotic situation. The FL condition resulted in distinct activations in the left inferior prefrontal gyrus and caudate nucleus, while the right inferior frontal gyrus and caudate were activated in both the FL and FR conditions, and in a non-instructed (NF) baseline condition.     

Ideology and Social Psychology

This article takes as critical point of departure the currently individualized nature of mainstream social psychology. It is argued that by using the concept of ideology, social psychology may be transformed into a more societal social psychology and thereby a discipline more relevant to individual, society and social life. Based on the interplay between language usage and ideology, moreover, a methodology for assessing ideological changes in society by identifying shifts in language usage in the public discourse (newspapers) is presented. Research conducted by this methodology, including comparative studies of how the globalized neoliberalism with its strong individualism merges with local ideologies in various societies around the world is then reviewed. Finally, analyses of a society’s ideological reactions upon terrorism, is presented.     

Burnout in the information technology sector: Does leadership matter?

The aim of the study was to examine subordinates' level of burnout in relation to how they perceive the leadership style of their direct superior. Subordinates (n = 289) in an Information Technology firm completed Maslach Burnout Inventory – General Survey, and rated their superior on the Multifactor Leadership Questionnaire. High subordinate burnout was defined as high exhaustion, high cynicism, and low professional efficacy. A structural equation model revealed that transformational leadership was significantly related to cynicism and professional efficacy, while passive-avoidance was significantly related to exhaustion and cynicism. Transactional leadership was not linked to burnout. Neuroticism in subordinates was directly related to all burnout components. The link between passive-avoidant leadership and burnout's key component exhaustion indicates perception of negative leadership behaviours is more important for burnout than perception of positive leadership styles.     

Neuropsychological performance in older insomniacs

ABSTRACT

The purpose of this study was to examine daytime performance in older adults fulfilling the diagnostic criteria for DSM-IV Insomnia, using a comprehensive battery of neuropsychological tests, and to compare these objective findings with measures of self-reported cognitive functioning. A total of 121 participants (69% women) with a mean age of 64.0 were part of a thorough neuropsychological examination at a University-based neuropsychological clinic in Western Norway. Twenty-five percent of the participants fulfilled the diagnostic criteria for insomnia. In sum, the insomnia patients were not different from the good sleepers on any neuropsychological test measure, and none of the results on the performance measures were associated with the sleep-related daytime complaints. However, the insomniacs did rate their subjective memory performance as significantly worse than the good sleepers, and they also reported more depressive symptoms. We conclude that DSM-IV defined insomnia was not associated with any performance based measure; only with self-reported symptoms.     

Self‐reported attitude scales: current practice in adequate assessment of reliability,validity, and dimensionality

The development of methods to create self‐reported attitude scales has lost momentum, in part because of increased research focused on implicit measures. This paper reviews 162 papers on methodological approaches applied to the validation and assessment of attitude scales. Assessment of methodological approaches applied indicates that neither reliability, validity, nor dimensionality assessments are consistently used according to standard operating procedures or in accordance with best practice. Within current practices in the field of attitude scale development, the full potential of self‐report scales is not met, in part because of such methodological issues. The improvement of existing practices and adoption of promising new developments in attitude scale construction and evaluation are discussed, together with recommendations for best practice in scale validation.     

Bioethics' Gender

I argue that the field of bioethics is gendered feminine, but that the methods it uses to resist this gender identity pose real harm to actual women. Starting with an explanation of what I take ‘gender’ to be, I enumerate four drawbacks to being gendered feminine. I then argue that bioethics suffers from three of the same four drawbacks. I show how the field escapes the fourth disadvantage by adopting a masculine persona that inflicts damage on women, and conclude by urging bioethicists to reflect on their complicity in abusive power systems such as gender, race and class.     

Executive functions and processing speed in children with mild to borderline intellectual disabilities and externalizing behavior problems

Several studies suggest impaired executive functions (EFs) in children with externalizing behavior problems and average intelligence (e.g., IQ > 85). Even though children with mild to borderline intellectual disabilities (MBID) are at higher risk of developing externalizing behavior problems compared to children with average intelligence, it is not yet clear if impaired EFs are also associated with the occurrence of externalizing behavior problems in children with MBID. In the current study, we therefore assessed three EF components (inhibition, cognitive flexibility, and working memory) as well as processing speed in children with MBID and externalizing behavior problems (n = 71) versus children with MBID with no such problems (n = 70). This was accomplished using a well-established computerized test battery. Even after IQ was controlled for, the children with MBID and externalizing behavior problems showed more impaired working memory performance. Differences for inhibition performance and processing speed were also found but less consistent across the tasks used to measure these aspects of EF. Cognitive flexibility was not more impaired in children with both MBID and externalizing behavior problems relative to children with MBID only. Our findings highlight working memory as a potential target to enhance the treatment of children with MBID and externalizing behavior problems.
