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.     

Sociolinguistic inference and intercultural coorientation.

We present a model that examines the effects of cultural differences on coorientation (the ability of communicators to accurately encode and interpret the referential and relational meanings of messages). Intercultural coorientation is made problematic by the absence of certain shared communication system knowledge, which in same‐culture interactions is used in the dynamic sociolinguistic negotiation of relational rights and obligations. We propose that the process of sociolinguistic negotiation of meanings relies fundamentally on probabilistic inference and have constructed a model based on Bayes' theorem. The model predicts the effects of the communication situation, communicator stereotypes and prejudice, and some other‐culture speaker errors on conclusions the receiver draws about the message. Using the model, we distinguish between the ethnocentric error of interpreting a communication in terms of one's own culture and the error of not seeing the communication as diagnostic. Among our predictions are: (a) the less diagnostic the communication, the more impact cultural stereotypes will have on attributions; (b) although evidence of sociolinguistic incompetence sometimes causes misunderstanding, it sometimes prevents misunderstanding; (c) multiple consistent features make intentions clearer than would a single cue, but multiple features violating co‐occurrence norms often lead to the attribution of incompetence.     

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.     

Valerian as a hypnotic for Hispanic patients

Valerian is a botanical used for its sedative effects whose central nervous system activity is ascribed to multiple constituents. Twenty-three established outpatient symptomatic Hispanic volunteers receiving mental health services at a large urban hospital participated in this case study. All complained of insufficient sleep. They were asked to try a popular national brand of valerian ("Nature's Way", 470 mg valerian root) and completed sleep questionnaires at baseline and at the end of Weeks 1 and 2. They were instructed to take 1 capsule each night before retiring and were allowed to increase their dose to a maximum of 3 capsules after Week 1. Twenty patients completed the trial. On an ordinal scale of 1 (no effect), 3 (moderately helpful), and 5 (extremely helpful), 16 patients rated their insomnia as at least "moderately improved" at the end of Week 1. By Week 2, 16 still rated themselves at least "moderately improved," but 15 of them now described their response as either a 4 or a 5. Global improvement at Week 2 was significantly better than at Week 1 (Wilcoxon ranks test p = .005), perhaps reflecting a time-dependent or dose-response relationship. This case study suggests that valerian can be a supplement for improving insomnia in a symptomatic population.     

Should I go with my gut? Investigating the benefits of emotion-focused decision making

Deliberative decision strategies have historically been considered the surest path to sound decisions; however, recent evidence and theory suggest that affective strategies may be equally as effective. In four experiments we examined conditions under which affective versus deliberative decision strategies might result in higher decision quality. While consciously focusing on feelings versus details, participants made choices that varied in complexity, in extent of subsequent conscious deliberation allowed, and in domain. Results indicate that focusing on feelings versus details led to superior objective and subjective decision quality for complex decisions. However, when using a feeling-focused approach, subsequent deliberation after encoding resulted in reduced choice quality. These results suggest that affective decision strategies may be more effective relative to deliberative strategies for certain complex decisions.     

The complementarity of apparent and real motion

Summary It is proposed that apparent motion does not parallel real motion. Bather, apparent motion occurs when the off-period is equivalent to angular velocities at which an object in real motion appears blurred. Experimental evidence is reported which supports this view. It suggests that apparent motion serves biologically to extend the range of motion perception beyond that allowed by time-constants early in the visual system.     

A “Classic” Revisited: Students' Immediate and Delayed Evaluations of a Warm/Cold Instructor

Solomon Asch's classic (1946) warm/cold research was replicated in this study with introductory psychology professors, using students' evaluations of teaching (SET) as dependent variables. Students completed attributed course evaluation forms three times: (a) after receiving fabricated warm or 'cold" information but before seeing the instructor; (b) after a 30–minute exposure to the instructor in an introductory lecture; and (c) at the end of the semester. In the first administration, strong warm/cold differences were found for the social components of SET, and warm instructors were also judged as more lenient. In the larger courses of Instructor B (but not in the smaller courses of Instructor A), the cold instructor was judged higher than the warm one in academic components of SET. In the second administration, following a 30–minute exposure to the instructor, students' judgments changed considerably, most warm/cold effects disappeared, and, unlike the common reports in the literature, we found only a moderate level of perseverance. In the third administration, all warm/cold differences practically disappeared, with no evidence of prolonged perseverance. These findings were interpreted as demonstrating students' flexibility in accommodating their judgments to the accumulating real-life information. It was argued that although cognitive factors determine a certain level of perseverance (especially in a short exposure), motivational factors and cognitive style play a major role in determining whether initial judgments will persevere or not. Students' personal beliefs in human changeability were found related to their actual change in judgment, incremental theorists (those believing in changeability) showing more change than entity theorists (those believing in fixed, unchangeable traits). Thus, perseverance of judgments is also related to systematic individual differences in students' cognitive style.
