Beyond Cultivation: Exploring the Effects of Frequency,Recency, and Vivid Autobiographical Memories for Violent Media

Using Shrum's (1996) heuristic processing model as an explanatory mechanism, we propose that people who hold vivid autobiographical memories for a specific past experience with media violence will overstate the prevalence of real-world crime versus individuals without vivid memories. We also explore the effects of frequency and recency on social reality beliefs. A survey was administered to 207 undergraduate students who were asked to recall one violent television program or movie seen in the past. Participants were asked to write essays describing the violence, which were coded for vividness. Results support not only cultivation theory, but also the effects of memory vividness: participants with more vivid memories of blood and gore gave higher prevalence estimates of real-world crime and violence than participants with less vivid memories. Findings also suggest that females had more vivid memories for prior media violence than males. Implications for cultivation, the heuristic processing model, and vividness research are discussed.     

Diabetes-specific social learning variables and self-care behaviors among persons with type II diabetes

This study assessed the relationship between diabetes-specific social learning factors and diabetes self-care. Predictor variables were collected within the categories of knowledge (e.g., behavioral demonstrations, pencil-and-paper tests), beliefs/expectations (e.g., self-efficacy, self-motivation), skills (e.g., problem-solving and refusal skills), and environmental support (e.g., barriers to adherence, family support). Different results emerged across the three areas of the regimen assessed: diet, exercise, and glucose testing. Multiple-regression analyses revealed that the social learning variables consistently improved the prediction of self-care beyond that attributable to demographic variables but that the categories of social learning variables most closely related to self-care varied across regimen areas. These findings suggest that programs to enhance diabetes self-care could beneficially focus on life-style behaviors and employ strategies to increase regimen-related expectations and diabetes-specific social and problem-solving skills.     

The medical context of parental coping with childhood cancer

This research assessed the extent to which contextual factors, especially the medical context, are related to the use of specific coping strategies by 74 parents of surviving children with cancer. Parents reported that they coped reasonably well by using information-seeking, problem-solving, help-seeking, maintaining emotional balance, relying on religion, being optimistic, denying, and accepting. More highly educated parents tended to use problem solving, optimism, and information seeking significantly more and denial significantly less than well-educated parents. However, gender and income were unrelated to coping. The use of specific coping strategies was not related to severity of the child's medical condition, stress level, or parents' own evaluations of their coping effectiveness. However, the quality of relations with the medical staff was strongly related to coping strategies. Use of passive coping strategies was positively related to good relations with the medical staff.     

Semantic mechanisms in paralexia

This study explores the effects of semantic constraints on the occurrence of paralexic responses in two patients who tend to produce semantic errors in reading aloud. In the first experiment, semantic constraints were provided by using words as proper names (e.g., “brown” vs. “Sam Brown”), and in the second by using short, highly familiar phrases to restrict the meaning of the target word (e.g., the polar bear; green with envy). These constraints were found to be effective in reducing the frequency of paralexic errors.     

The word order problem in agrammatism : II. Production

This study demonstrates that agrammatic aphasics have difficulty describing relations that are signified by the order of noun phrases around verbs or prepositions. The word order deficit is found in a Sentence Order Task, in which written words must be arranged linearly to form a sentence, as well as in oral production. Ordering tendencies reflect factors like animacy or potency, rather than the systematic use of syntactic rules. These results point to a fundamental syntactic disorder in agrammatism.     

Prejudice Toward Immigrants1

In the present study, 4 variables (realistic threats, symbolic threats, intergroup anxiety, and negative stereotypes) were used to predict prejudice toward immigrants from Cuba, Mexico, and Asia in samples of students from states in the United States that are affected by immigration from these areas (Florida, New Mexico, and Hawaii, respectively). All 4 variables were significant (or marginally significant) predictors of attitudes toward these immigrant groups. Evidence is presented that the predictor variables are conceptually and empirically distinct. However, these variables do appear to be tied together by an underlying theme: They all concern threats to the in-group or its members. Some of the implications of the results for intergroup relations are discussed.     

Observing responses in pigeons

Pigeons were trained on an observing-response procedure in which periods of VR 100 and EXT alternated unpredictably during a white light (mixed stimulus). During VR 100, responses on a food-producing key (the first key) were intermittently reinforced. Responses on the observing key (the second key) produced a green light (positive stimulus) when VR 100 was in effect, and a red light (negative stimulus) for EXT. The birds did not respond on either key during the negative stimulus, but they responded on the food-producing key when the positive stimulus appeared. When observing responses produced the positive or negative stimulus on FR, observing responses were maintained until the FR reached a maximum; beyond this, only food-producing responses occurred. When observing responses did not produce either stimulus, the observing-response rates fell to zero. With prolonged exposure to an FR 20 schedule of observing, observing-response rates during EXT were higher than during VR 100. Chlorpromazine hydrochloride decreased the total response output but markedly increased observing-response rates except when it was administered before sessions of observing response extinction.     

The effects of realistic threat and group identification on social dominance orientation

Based on social identity and intergroup threat theories, we argue that social dominance orientation (SDO) can increase as a result of realistic threat, or perceived obstacles to the ingroup’s position and general welfare. However, this effect should be strongest among highly-identified group members, who are particularly concerned with protecting their ingroup against threat. Study 1 found that among non-Asian Americans, racial group identification moderated the relationship between perceptions of realistic threat from Asian Americans and SDO. Study 2 replicated Study 1 using an experimental, rather than correlational, design. Using different social groups, Study 3 showed that non-science college majors who identified strongly with their field of study exhibited higher SDO after being made to feel threatened by science majors. The results from these studies have implications for research on the meaning and antecedents of SDO.     

Effects of social stress on tumor development in dominant male mice with diverse behavioral activity profiles

We examined the influence of individual psychological profile and social behavior on tumor development in dominant male mice. Male OF1 mice were subjected to an open field test (OFT) to observe their motor activity and latency. Subsequently, the animals were divided into three groups: Stress-Non-Inoculated (SNI), Stress-Inoculated (SI) and Control-Inoculated (CI). The SI and CI groups were inoculated with tumor cells and the SNI group with vehicle. SNI and SI were exposed to social stress with an anosmic intruder six (T1) and twenty one (T2) days after inoculation and their behavior was analyzed. After T2, subjects were put down and the pulmonary metastatic foci counted. SI developed greater pulmonary metastasis than CI, indicating an effect of stress despite the animal's dominant status. Active animals developed less pulmonary metastasis than their passive counterparts. No differences were found in social behavior at T1. Differences were found, however, in some behavioral categories at T2 between SI and SNI, and between active and passive animals. These differences indicate an effect of tumor development on social behavior that is more evident in passive subjects.
