The Role of Hope in the Psychological Adjustment of Gastropareutic Patients Receiving the Gastric Pacemaker: A Longitudinal Study

Hope, depressive symptoms, anxiety, and physical quality of life (QOL) were assessed in three subgroups of patients receiving the gastric pacemaker. Patients (n = 22) completed questionnaires prior to pacemaker implantation and at 3 and 6 months post-surgery. The idiopathic subgroup reported a significantly greater degree of hope and less anxiety at 6-month follow-up, compared to the diabetes patients. The idiopathic patients also reported significantly less anxiety at 6 months than the postsurgical patients. Across all subgroups, there was an increase in hope and physical QOL, and decrease in depressive symptoms and anxiety, from baseline levels. There was a significant negative relationship between hope and both depressive symptoms and anxiety at baseline and 3- and 6-month follow-up. Presurgical hope level did not significantly predict depressive symptoms or anxiety after implantation. This study provides evidence that the pacemaker improves the physical and psychological health of gastropareutic patients; hope appears to play a role in the psychological adjustment of these patients.     

Construct validity and personality correlates of the Strelau temperament inventory

Strelau's reinterpretation of Pavlov's concept of nervous system properties has gained increasing attention in Western personality research, both with regard to the psychometric properties of the Strelau Temperament Inventory (STI) and with regard to the interrelations between STI and Western personality dimensions. The present study investigated the construct validity of the Strength of Excitation scale by examining its relationship to experimental indices of strength of the nervous system. Secondly, data on the convergence between STI, EPQ, SSS IV, and trait anxiety measures are presented, using German translations of all the questionnaires. The results confirmed the correlation between strength of excitation and a reaction time based measure of strength of the nervous system. A factor analysis on the questionnaire scales identified two factors. Factor I (activity/stimulation seeking) consisted of extroversion, mobility, strength of excitation and the sensation seeking scales whereas Factor II (instability vs control) was composed of anxiety/neuroticism/ psychoticism and strength of excitation/strength of inhibition/social desirability. These findings agree with Eysenck's and Strelau's theoretical predictions regarding the interrelations of Pavlovian properties and Western personality dimensions.     

“Insightful” string-pulling in Grey parrots (<Emphasis Type="Italic">Psittacus erithacus</Emphasis>) is affected by vocal competence

Four Grey parrots (Psittacus erithacus) were tested on their ability to obtain an item suspended from a string such that mutiple, repeated, coordinated beak–foot actions were required for success (e.g., Heinrich 1995). Those birds with little training in referential English requests (e.g. I want X) succeeded, whereas birds who could request the suspended item failed to obtain the object but engaged in repeated requesting.Electronic Supplementary Material Supplementary material is available in the online version of this article at     

A note on reflex sensitivity and formation of conditioned responses

The relationship between ease of conditioning and reflex sensitivity was examined in the GSR and blink reflex under two experimental conditions. Significant positive correlations were obtained between a variety of response characteristics (e.g. frequency, amplitude of blink, spontaneous GSRs) and the number of conditioned responses, thus supporting earlier findings obtained on different reflex measures.

Various anatomical and physiological factors which may influence reflex sensitivity are indicated, and the need to analyse these factors is stressed, especially in the context of those theories which postulate a general factor of conditionability.     

The automaticity of race and Afrocentric facial features in social judgments

Four experiments were conducted to examine the automaticity of stereotyping based on racial category and (within-race) Afrocentric facial features. Results showed that both forms of stereotyping are efficient processes, able to operate when cognitive resources are highly restricted. The 2 differed, however, in their controllability. Participants demonstrated that they were sensitized to race-based stereotypes and able to control that influence to a significant degree. In contrast, participants appeared to be largely unaware of using Afrocentric features to make stereotypic inferences, and they proved unable to avoid doing so, even when they were given explicit information about the process and they demonstrated that they could easily and reliably identify the relevant features.
