Contrasting visuomotor functions of tectum and cortex in the golden hamster

Summary Visually-guided orientation (spatial localization) and visual discrimination were dissociated by means of brain lesions in the golden hamster. After ablation of visual cortex, hamsters failed to discriminate visual patterns, but showed nearly normal ability to localize an object in space by means of vision. Ablation of the superior colliculus produced opposite effects: these animals were completely unable to orient to the position of a visual stimulus, but nevertheless showed excellent pattern discrimination.

Zusammenfassung Visuell gesteuerte Orientierung (räumliche Lokalisation) und visuelles Unterscheidungsvermögen beim Goldhamster werden durch Hirnläsionen funktionell getrennt. Nach Entfernung der Sehrinde können die Tiere keine visuellen Musterunterscheidungen, wohl aber noch in fast normaler Weise visuelle Objektlokalisationen vornehmen. Entfernung des Colliculus superior führt zu entgegengesetzten Effekten: die Tiere können sich nicht mehr nach der Position eines visuellen Reizes orientieren, zeigen aber trotzdem ausgezeichnete Musterunterscheidung.

Finding Sandra: Dr. Beebe’s Second as Analytic Third: A Discussion of “A Patient Who Does Not Look: A Collaborative Treatment with Video Feedback”

Larry Sandberg and Beatrice Beebe (this issue) offer a moving account of their work with Sandra, a gaze-averse woman with a painful and traumatic childhood history. Drs. Sandberg and Beebe describe their work together in the context of an innovative conjoint treatment model including psychotherapy, video feedback consultation, and dance movement therapy. Dr. Beebe’s Interventions at the sensorial, bodily, and affective register facilitated Sandra’s movements from being in the grips of a terrifying object world, to an experience of companioning with Dr. Beebe, giving her a greater sense of holding and emotional security. Further, “Dr. Beebe’s Second,” an image from Dr. Beebe’s own reverie offered Sandra an “emotional third”; a new found internal experience of herself-with-others that helped her lift her gaze to the future.     

Person–Organisation Fit Across Cultures: An Empirical Investigation of Individualism and Collectivism

The present study extended person–organisation fit research by concentrating exclusively on one national culture dimension affecting organisational values: individualism–collectivism (I–C). Volunteers ( N =581) from two matched organisations (hospitals and management consultancies) in Australia and in South‐East Asia completed questionnaires measuring individuals' orientations on I–C and other organisational variables. Two types of fit were analysed: interactions between (1) individual I–C and national culture, and (2) individual I–C and organisational culture. These interactions were tested in relation to three outcome variables: organisational commitment, job satisfaction, and tenure. Both national and organisational differences were found with respect to I–C. Asian organisations were more collectivistic than Australian organisations, and hospitals were more collectivistic than management consultancies. In support of person–nation fit hypotheses, collectivists were more committed to their organisations and had longer tenure than individualists in Asian, as compared to Australian organisations. Interaction terms were significant even in the presence of direct effects of collectivism on organisational commitment and tenure. The same results were not found for job satisfaction. Predicted effects of person–organisation fit were not found at the organisational level within cultures.
