The Role of Accent on the Credibility and Effectiveness of the Salesperson

The study focuses on assessing the impact of a salesperson's accent on people's perception of his effectiveness, including credibility, competence, friendliness, and intentions to buy. One hundred and forty-six students listened to tape recordings of three presenters speaking with Greek-accented English and three presenters speaking with standard American accent. The message was a hypothetical sales pitch for a VCR. The results indicate that, for an American audience, a sales pitch in standard American accent evoked more favorable judgments on all measured dimensions than Greek-accented English.     

Self‐judgment and reputation monitoring as a function of the fundamental dimensions,temporal perspective,and culture

Social acceptance and the development of one's competencies and status are fundamental aspects of the human experience, but the former (communion) should take precedence over the latter (agency) in self‐judgment. Study 1 results indicated that (i) people across two cultures judged themselves as possessing higher communion than agency characteristics; (ii) communion self‐judgments were more consistent across temporal perspective; and (iii) level of self‐enhancement across cultures was similar for communion but different for agency. In Study 2, people across culture reported being more troubled and demonstrated a greater desire to repair their reputation when they imagined others perceived them as lacking in communion compared with agency. These findings support the idea that social life pressures people to view themselves as possessing communion traits and to ensure that others have this perception as well.

Attenuated response to methamphetamine sensitization and deficits in motor learning and memory after selective deletion of β-catenin in dopamine neurons

In the present study, we analyzed mice with a targeted deletion of β-catenin in DA neurons (DA-βcat KO mice) to address the functional significance of this molecule in the shaping of synaptic responses associated with motor learning and following exposure to drugs of abuse. Relative to controls, DA-βcat KO mice showed significant deficits in their ability to form long-term memories and displayed reduced expression of methamphetamine-induced behavioral sensitization after subsequent challenge doses with this drug, suggesting that motor learning and drug-induced learning plasticity are altered in these mice. Morphological analyses showed no changes in the number or distribution of tyrosine hydroxylase-labeled neurons in the ventral midbrain. While electrochemical measurements in the striatum determined no changes in acute DA release and uptake, a small but significant decrease in DA release was detected in mutant animals after prolonged repetitive stimulation, suggesting a possible deficit in the DA neurotransmitter vesicle reserve pool. However, electron microscopy analyses did not reveal significant differences in the content of synaptic vesicles per terminal, and striatal DA levels were unchanged in DA-βcat KO animals. In contrast, striatal mRNA levels for several markers known to regulate synaptic plasticity and DA neurotransmission were altered in DA-βcat KO mice. This study demonstrates that ablation of β-catenin in DA neurons leads to alterations of motor and reward-associated memories and to adaptations of the DA neurotransmitter system and suggests that β-catenin signaling in DA neurons is required to facilitate the synaptic remodeling underlying the consolidation of long-term memories.     

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.     

Cross-national stereotypes of locus of control in university students1

Stereotypes of locus of control were studied in male and female university students from eight countries (Canada, France, West Germany, India, Israel, Italy, Japan, United States). The subjects took the Rotter Internal-External Locus of Control (I-E) Scale in standard fashion (“own” scores) and then in the role of students similar to themselves in their own country (attributed own) and in selected other countries (attributed other). Using the difference between “own” scores and “attributed” scores as the operational measure of stereotype, the results indicate (1) that scores attributed to students in a given country bear little relationship to those students “own” scores, thereby suggesting the presence of stereotypes of locus of control; (2) students in most countries attribute greater externality to the average student in their own country compared to themselves; (3) countries vary in the degree to which they stereotype other countries with the U.S. students significantly attributing greater externality to other countries and Japanese students significantly attributing greater internality to other students; (4) countries vary in the degree to which they are stereotyped with German students perceived as most internal and Italian students as most external; (5) the U.S.S.R. and U.S.A. are perceived differently on content subscales of the I-E Scale although their overall attributed scores do not differ.     

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.
