Processing strategy moderates the cultivation effect

This study tested the hypothesis that processing strategy moderates the effect of television viewing on social perceptions (cultivation effect). One hundred twenty‐two male and female students provided estimates of the prevalence of crime, occupations, affluence, and marital discord under one of three conditions. Some participants were induced to process heuristically (heuristic group) through instructions to provide their estimates spontaneously with little elaboration. Other participants were induced to process systematically (systematic group) through an accuracy motivation/task importance manipulation. A third (control) group received instructions to simply answer the questions. The results indicated that processing strategy moderated the cultivation effect such that cultivation effects were noted in the heuristic and control groups but not in the systematic group. These results are consistent with the notion that the cultivation effect can be explained in part as the result of heuristic processing through lack of source discounting, and they provide support for the heuristic processing model of cultivation effects.     

An Investigation of Psychology Staffing in Australian Metropolitan Acute Public Hospitals

Psychology is one component of the multidisciplinary services provided to patients in acute public hospitals, with research demonstrating that psychological intervention significantly enhances clinical outcomes for patients across a range of health issues. Despite the increasingly important role that psychologists play in Australian hospitals, there remains a lack of information available about staff levels, discipline structures, and clinical activity for psychological services within acute hospital settings. The most recent Australian data about hospital‐based psychology services was collected 20 years ago. The current study provides updated information from a survey of 15 Australian metropolitan, acute public hospitals: presenting and critically reviewing staffing configurations and models of service delivery. Results suggest that: (a) hospitals employ a highly skilled workforce at a rate of 0.16 full‐time equivalent psychology staff for every 10 hospital beds; (b) psychologists have a viable career pathway within the hospital‐based health sector; (c) role diversity is common, with the primary focus varying as a function of position level; (d) neuropsychology staffing requires urgent attention to address significant delays in access to services; and (e) public hospitals actively contribute to current and future workforce development through supervision, research, and training. The implications of these results for the future of psychological services in Australian healthcare are discussed.     

Serotonin transporter knockout rats show improved strategy set-shifting and reduced latent inhibition

Behavioral flexibility is a cognitive process depending on prefrontal areas allowing adaptive responses to environmental changes. Serotonin transporter knockout (5-HTT(-/-)) rodents show improved reversal learning in addition to orbitofrontal cortex changes. Another form of behavioral flexibility, extradimensional strategy set-shifting (EDSS), heavily depends on the medial prefrontal cortex. This region shows functional changes in 5-HTT(-/-) rodents as well. Here we subjected 5-HTT(-/-) rats and their wild-type counterparts to an EDSS paradigm and a supplementary latent inhibition task. Results indicate that 5-HTT(-/-) rats also show improved EDSS, and indicate that reduced latent inhibition may contribute as an underlying mechanism.
