Self-controlled visual discrimination learning of group-housed dwarf goats (Capra hircus): behavioral strategies and effects of relocation on learning and memory

In most studies on animal learning, individual animals are tested separately in a specific learning environment and with a limited number of trials per day. An alternative approach is to test animals in a familiar environment in their social group. In this study, the authors--applying a fully automated learning device--investigated voluntary, self-controlled visual shape discrimination learning of group-housed dwarf goats (Capra hircus). The majority of the tested goats showed successful shape discrimination, which indicates the adaptive value of an effective learning strategy. However, in each group, a few individual goats developed behavioral strategies different from shape discrimination to get reward. Relocation impairs memory retrieval (probably by attention shifting) only temporarily for previously learnt shapes. The results demonstrate the usefulness of a self-controlled learning paradigm to assess learning abilities of social species in their normal social settings. This may be especially relevant for captive animals to improve their welfare.     

Tinnitus Stages of Change Questionnaire: psychometric development and validation

This study describes the development of the Tinnitus Stages of Change Questionnaire (TSOCQ), which aims to assess the readiness of tinnitus patients to change their behaviors and attitudes in relation to tinnitus. Its ability to predict treatment outcome was also investigated. One hundred and fifty-one patients with tinnitus completed the questionnaire. Through repeated principal component analyses, together with judgments of the factors' theoretical relevance, empirically and clinically meaningful scales were derived. A factor solution in accordance with the transtheoretical model (TTM) and with acceptable psychometric properties was found with the five scales of the TSOCQ labeled Precontemplation (Medical Solution), Precontemplation (Helplessness), Contemplation, Preparation and Action/Maintenance. Participants scoring high on Precontemplation (Helplessness) and low on Action/Maintenance had better treatment outcomes. In conclusion, the TSOCQ had some ability to predict treatment success, but further research is required into the utility of the TTM for understanding the rehabilitation process in tinnitus patients.

Treatment of panic disorder: live therapy vs. self-help via the Internet

A randomized trial was conducted comparing 10 individual weekly sessions of cognitive behaviour therapy for panic disorder (PD) with or without agoraphobia with a 10-module self-help program on the Internet. After confirming the PD diagnosis with an in-person structured clinical interview (SCID) 49 participants were randomized. Overall, the results suggest that Internet-administered self-help plus minimal therapist contact via e-mail can be equally effective as traditional individual cognitive behaviour therapy. Composite within-group effect sizes were high in both groups, while the between-group effect size was small (Cohen's d=16). One-year follow-up confirmed the results, with a within-group effect size of Cohen's d=0.80 for the Internet group and d=0.93 for the live group. The results from this study generally provide evidence to support the continued use and development of Internet-distributed self-help programs.     

Randomized controlled trial of internet-based stress management

This study investigated the effects of an internet-based self-help stress management program with a randomized controlled design. Of 85 participants, 26% dropped out, leaving a final sample of 63 participants with 23 in the treatment group and 40 in the waiting list control group. Treatment included applied relaxation, problem solving, time management and cognitive restructuring. All information and treatment interventions were provided via the internet. Results were evaluated with the Perceived Stress Scale and the Hospital Anxiety and Depression Scale. Improvements were seen in both groups, with greater improvements in the self-help treatment group. It is concluded that the internet can be used to provide stress management techniques and result in stress relief. However, spontaneous improvement, differential dropout rate and compliance need to be monitored in future studies.     

Limits of morality: A sociological approach to higher moral stages

Grounded in the wider framework of Kohlberg's (1984) stage theory of moral development and Habermas' (1981; Habermas &; Luhmann, 1971) theory of discourse, this article addresses the question: Is a moral stage 6 society possible? Toward answering this question, a sociological approach to moral stage 6 is employed that complements the usual psychological approach to moral development. The article posits that a moral stage 6 society is impossible. Therefore, lower-stage institutions cannot be abolished; they have to be controlled and supervised. This calls for a new and structurally different type of discourse, the metadiscourse. The article postulates that such metadiscourse has the property of moral stage 7 according to the general stage model (Commons &; Richards, 1984a, 1984b). Finally, several strategies for controlling lower-stage institutions are considered, with bureaucracy serving as example of a lower-stage institution.     

Involvement of cardiac,respiratory and gastrointestinal functions in neural responses to stressful events

In the stress concept, fight and flight situations as well as other CNS-controlled reaction patterns for alertness to danger have to be followed by or integrated with a restorative “build-up” process in order to maintain homeostasis. The “build-up” process can be studied physiologically for example after regular exercise or training. Under these conditions there is a decrease in resting sympathetic adrenergic activity and an increase in the parasympathetic vagal activity. A theoretical model for the “build-up” process in psychosomatic gastroenterology has previously been presented. The present paper deals with the “build-up” process in cardiovascular and respiratory tract diseases seen in athletes. Anorexia nervosa related to excess physical training is also discussed as well as the “build-up” process in severe obesity and psychosomatic gastroenterological disorders.
