Quantitative EEG analysis of a single dose of psychotropic drugs in healthy probands

In a series of 74 experiments in a double blind study, 25 healthy test persons were medicated with a single dose of Clomipramin, Desipramin, Imipramin, Diazepam, Carbamazepin, Haloperidol, and a placebo. At the end of one hour, and again at the end of three hours, an EEG was made whose frequency analysis revealed significant changes in about half the test persons. The antidepressives induced an increase in the theta waves, the slow alpha waves, and the slow beta waves, and a decrease in the fast alpha waves. The factors influencing the EEG are discussed.     

Measuring reaction times in healthy probands before and following a single dose of psychotropic drugs

A single dose of Clomipramin, 50 mg; Amitriptylin, 50 mg; Desipramin, 50 mg; Imipramin, 50 mg; Diazepam, 10 mg; Carbamazepin, 200 mg; Haloperidol, 3 mg; were each administered orally, and Clomipramin, 25 mg was administered intravenously, and reaction times were measured and compared with those obtained after administering a placebo. The statistical examination was conducted using Wilcoxon's test. In the case of Amitriptylin, Diazepam, and Haloperidol, there was a statistically significant reduction in the reaction times.     

Balance between volunteer work and family roles: Testing a theoretical model of work‐family conflict in the volunteer emergency services

Trends indicate overall declines in numbers of volunteer emergency service workers and suggest negative organisational factors impacting adversely on volunteers and organisations. Conflict between emergency service work and family is implicated in falling volunteer numbers, and there is thus a need for research on difficulties experienced in balancing volunteer work and family. The current study tested an adaptation of the work‐family conflict (WFC) model originally proposed by Frone, Russell, and Cooper, in a sample of 102 couples in which one partner was an Australian emergency service volunteer. Results supported a model in which volunteer work‐related antecedents, including time invested in on‐call emergency activities and post‐traumatic stress symptoms, had indirect links with outcomes, including volunteer burnout and their partners' support for the volunteer work role, through the effects of WFC. These results add to research using theoretical models of paid work processes to better understand the problems faced by volunteer workers, and identify specific antecedents and outcomes of WFC in the volunteer emergency services. Implications for future research and organisations reliant on volunteer workers are discussed.     

Positive association between cognitive ability and cortical thickness in a representative US sample of healthy 6 to 18 year-olds

Neuroimaging studies, using various modalities, have evidenced a link between the general intelligence factor (g) and regional brain function and structure in several multimodal association areas. While in the last few years, developments in computational neuroanatomy have made possible the in vivo quantification of cortical thickness, the relationship between cortical thickness and psychometric intelligence has been little studied. Recently, cortical thickness estimations have been improved by the use of an iterative hemisphere-specific template registration algorithm which provides a better between-subject alignment of brain surfaces. Using this improvement, we aimed to further characterize brain regions where cortical thickness was associated with cognitive ability differences and to test the hypothesis that these regions are mostly located in multimodal association areas. We report associations between a general cognitive ability factor (as an estimate of g) derived from the four subtests of the Wechsler Abbreviated Scale of Intelligence and cortical thickness adjusted for age, gender, and scanner in a large sample of healthy children and adolescents (ages 6–18, n = 216) representative of the US population. Significant positive associations were evidenced between the cognitive ability factor and cortical thickness in most multimodal association areas. Results are consistent with a distributed model of intelligence.     

Dynamics of the general factor of personality in response to a single dose of caffeine

General Factor of Personality (GFP) research is an emergent field in personality research. This paper uses a theoretical mathematical model to predict the short-term effects of a dose of a stimulant drug on GFP and reports the results of an experiment showing how caffeine achieves this. This study considers the General Factor of Personality Questionnaire (GFPQ) a good psychometric approach to assess GFP. The GFP dynamic mechanism of change is based on the Unique Trait Personality Theory (UTPT). This theory proposes the existence of GFP which occupies the apex of the hierarchy of personality, and extends from an impulsiveness-and-aggressiveness pole (approach tendency) to an anxiety-and-introversion pole (avoidance tendency). An experiment with 25 volunteers was performed. All the participants completed the GFPQ and the Sensation-Seeking Scale list of adjectives from the trait version of MAACL-R (Multiple Affect Adjective Checklist Revised) on an empty stomach. The participants in the experimental group (20) received 330 mg of caffeine. All the participants filled in a state version form with the sensation-seeking adjectives every 4.5 minutes. This study considers that the Sensation-Seeking Scale list of adjectives from the MAACL-R, available in both trait and state versions, is a good psychometric approach to assess GFP. The results show that GFP is modified by a single dose of caffeine in the direction predicted by the UTPT.

Testing the difficulty theory of the SON‐R –17, a non‐verbal test of intelligence

Fischer's (1973) linear logistic test model can be used to test hypotheses regarding the effect of covariates on item difficulty and to predict the difficulty of newly constructed test items. However, its assumptions of equal discriminatory power across items and a perfect prediction of item difficulty are never absolutely met. The amount of misfit in an application of a Bayesian version of the model to two subtests of the SON‐R –17 is investigated by means of item fit statistics in the framework of posterior predictive checks and by means of a comparison with a model that allows for residual (co)variance in the item parameters. The effect of the degree of residual (co)variance on the robustness of inferences is investigated in a simulation study.

Casework towards the family re-integration of a sexually abusive father—a single case study

A family is presented where sexual abuse of one child had occurred but the family wished to stay together. Work with the family over 3 years, during which time the father served a prison sentence, is described.
The problems, for professionals as well as the family, in deciding when a family is safe are discussed.     

Volunteerism in a Community‐Based Sample of Women Aged 50 to 80 Years1

This paper has 2 purposes: (a) to present the differences in demographic and health characteristics of older women volunteers and nonvolunteers in a community‐based sample; (b) to identify the motivations of current and past volunteers, as contrasted with those who have never volunteered. A population‐based survey was conducted with a sample of 1,104 women aged 50 to 80 years in the state of Washington. Nonvolunteers were less likely to be married and were slightly less likely to be White than were current or past volunteers. Demographic variables (e. g., age) and health status predicted level of reported motivation for volunteering. These data provide us with population‐based estimates of volunteering and motivations for older women.     

Intrinsic need satisfaction and the job attitudes of volunteers versus employees working in a charitable volunteer organization

This research examines how intrinsic need satisfaction during volunteer work relates to the job attitudes of volunteers ( Deci & Ryan, 2000 ; Ryan & Deci, 2000 ). We distinguish between autonomy, competence, and relatedness needs, and predict these to have distinct effects on volunteers' job satisfaction and intent to remain with the volunteer organization. We then compare volunteer workers to a matched sample of paid employees (performing identical tasks within the same organization) in the way in which they derive their job satisfaction and intent to remain from satisfaction of these three types of needs. As predicted, path analysis (N=105) shows that satisfaction of autonomy needs and relatedness needs are positively related to the intent to remain a volunteer with the volunteer organization, and this relation is mediated by satisfaction with the volunteer job. The matched samples comparison further reveals that whereas the job satisfaction and intent to remain of paid employees is most clearly predicted by satisfaction of autonomy needs, satisfaction of relatedness needs is the primary predictor of job satisfaction and intent to remain among volunteers. Theoretical and practical implications, as well as avenues for further research, are discussed.     

Liability of professional and volunteer mental health practitioners in the wake of disasters: a framework for further considerations

Qualified immunity from civil liability exists for acts of disaster mental health (DMH) practitioners responding to disasters or acts of terrorism. This article reviews current legal regimens dictating civil liability for potentially wrongful acts of DMH professionals and volunteers responding to disasters. Criteria are proposed to inform determinations of civil liability for DMH workers in disaster response, given current legal parameters and established tort law in relevant areas. Specific considerations are examined that potentially implicate direct liability of DMH professionals and volunteers, and vicarious liability of DMH supervisors for actions of volunteer subordinates. The relevance of pre-event DMH planning and operationalization of the plan post-event is linked to considerations of liability. This article concludes with recommendations to minimize liability exposure for DMH workers in response efforts.     

Information distortion in the evaluation of a single option

Extending previous work on biased predecisional processing, we investigate the distortion of information during the evaluation of a single option. A coherence-based account of the evaluation task suggests that individuals will form an initial assessment of favorability toward the option and then bias their evaluation of subsequent information to cohere with their initial disposition. Three experiments tested this hypothesis. Initial disposition was manipulated (Studies 1 and 3) or measured (Study 2), and attribute ratings were collected as indicators of information distortion. Results from all three experiments indicate that attribute evaluations were biased to favor initial dispositions. These findings provide evidence that information distortion is one cause of primacy effects in judgment and decision-making settings involving a single option.     

Cognitive development as an executive process – in part: a homeopathic dose of Piaget

Piaget’s theory of cognitive development retains its importance through showing us how the exercise of agency is necessary to the development of self–world dualism and to the developing ability to frame explicit judgements about the physical and mental world. I begin by describing the Piagetian position in my own terms (Agency: Its role in mental development, 1996, for a fuller account) and then set it in the context of research on the executive functions. I also argue, however, that the theory lacks the resources to explain second-order mental representation. The theory was insufficiently nativist in general and insufficiently nativist about symbolic capacities in particular. But adopting a nativist view does not preclude one from taking a Piagetian line on the essential contribution of the first-person experience of agency to cognitive development.
