Hostility, anger, aggressiveness, and coronary heart disease: an interpersonal perspective on personality, emotion, and health

The related traits of hostility, anger, and aggressiveness have long been suggested as risk factors for coronary heart disease (CHD). Our prior review of this literature (Smith, 1992) found both considerable evidence in support of this hypothesis and important limitations that precluded firm conclusions. In the present review, we discuss recent research on the assessment of these traits, their association with CHD and longevity, and mechanisms possibly underlying the association. In doing so, we illustrate the value of the interpersonal tradition in personality psychology (Sullivan, 1953; Leary, 1957; Carson, 1969; Kiesler, 1996) for not only research on the health consequences of hostility, anger, and aggressiveness, but also for the general study of the effects of emotion, personality and other psychosocial characteristics on physical health.     

The importance of material-processing interactions in inducing false memories

Deep encoding, relative to shallow encoding, has been shown to increase the probability of false memories in the Deese/Roediger-McDermott (DRM) paradigm (Thapar & McDermott, 2001; Toglia, Neuschatz, & Goodwin, 1999). In two experiments, we showed important limitations on the generalizability of this phenomenon; these limitations are clearly predicted by existing theories regarding the mechanisms underlying such false memories (e.g., Roediger, Watson, McDermott, & Gallo, 2001). Specifically, asking subjects to attend to phonological relations among lists of phonologically associated words (e.g., weep, steep, etc.) increased the likelihood of false recall (Experiment 1) and false recognition (Experiment 2) of a related, nonpresented associate (e.g., sleep), relative to a condition in which subjects attended to meaningful relations among the words. These findings occurred along with a replication of prior findings (i.e., a semantic encoding task, relative to a phonological encoding task, enhanced the likelihood of false memory arising from a list of semantically associated words), and they place important constraints on theoretical explanations of false memory.     

Time of day-dependent latent inhibition of conditioned taste aversions in rats

We have determined that the temporal context of drinking can modulate latent inhibition of learned saline aversions in Wistar rats by changing the time of day of drinking of the preexposure and conditioning phases. Latent inhibition was absent in the group preexposed and conditioned to saline at different times of the day, but not in the group that was preexposed and conditioned at the same time of day. The results confirm a previous report that the time of day can modulate taste aversion learning independently of other environmental cues. It is proposed that the features and duration of the habituation training to the temporal contexts used may be critical for time-dependent latent inhibition to appear.     

Get' em While They Last! Effects of Scarcity Information in Job Advertisements

Participants in Study 1 ( N = 172) were presented with a restaurant server advertisement differing by vacancy availability (scarce vs. plentiful) and scarcity type (number of vacancies vs. time to apply). Companies advertising only a few vacancies available were perceived as paying a significantly higher hourly wage than companies advertising many vacancies available. Also, both vacancy scarcity and time scarcity had positive effects on various company-image perceptions. Study 2 ( N = 181) replicated most of the findings in Study 1 using a different entry-level job advertisement. However, although presentation mode (i.e., advertisement vs. factual) had a main effect on intention to apply, it did not interact with vacancy scarcity.     

Creating False Memories of Words with or without Recognition of List Items: Evidence for Nonconscious Processes

Subjects exposed to lists of semantically related words falsely remember nonstudied words that are associated with the list items (e.g., Deese, 1959; Roediger & McDermott, 1995). To determine if subjects would demonstrate this false memory effect if they were unable to recognize the list items, we presented lists of semantically related words with or without a concurrent memory load at rates of 2 s, 250 ms, or 20 ms per word (Experiment 1, between-subjects design) and 2 s or 20 ms per word (Experiment 2, within-subjects design). We found that the subjects falsely recognized semantically related nonstudied words in all conditions, even when they were unable to discriminate studied words from unrelated nonstudied words. Recognition of list items was unnecessary for the occurrence of the false memory effect. This finding suggests that this memory illusion can be based on the nonconscious activation of semantic concepts during list presentation.     

Predicting emotional concomitants of learned helplessness: The role of motivational orientation

Previous theoretical and empirical analyses indicate that an extrinsic motivational orientation, i.e., performing activities to please others or concern with criticism, predicts the cognitive and behavioral deficits associated with learned helplessness. Conversely, intrinsically motivated students, who perform activities for the inherent pleasure of mastery over challenge, have been shown to be virtually resilient to successive failure experiences and even show a facilitation effect. However, research has not yet addressed the extent to which motivational orientation predicts the emotional deficits associated with helplessness—namely, depression and a maladaptive attributional style. Furthermore, no research has examined the relative predictability of these variables to investigate subjects' feelings after an experimental manipulation of failure. The present research found support for the proposition that an extrinsic motivational orientation predicts depression and the Expanded Attributional Style Questionnaire. More importantly, our findings demonstrated that an extrinsic motivational orientation was a more reliable predictor of subjects' feelings after a failure manipulation than either depression or a maladaptive attributional style. These findings are discussed in light of intervention strategies to attenuate the development of an extrinsic motivational orientation in students.     

Associative false recognition occurs without strategic criterion shifts

In the DRM (Deese/Roediger and McDermott) false memory paradigm, subjects studied lists of words associated with nonpresented critical words. They were tested in one of four instructional conditions. In a standard condition, subjects were not warned about the DRM Effect. In three other conditions, they were told to avoid false recognition of critical words. One group was warned before study of the lists (affecting encoding and retrieval processes), and two groups were warned after study (affecting only retrieval processes). Replicating prior work, the warning before study considerably reduced false recognition. The warning after study also reduced false recognition, but only when critical items had never been studied; when critical items were studied in half the lists so that subjects had to monitor memory for their presence or absence, the warning after study had little effect on false recognition. Because warned subjects were trying to avoid false recognition, the high levels of false recognition in the latter condition cannot be due to strategically guessing that critical test items were studied. False memories in the DRM paradigm are not caused by such liberal criterion shifts.     

Evaluation of communicative and linguistic development using the Spanish version of the MacArthur-Bates inventories

The MacArthur-Bates Inventories are a valid and reliable method for assessing communicative and linguistic skills in infants (8-15 months) and young children (16-30 months), and have been adapted to many languages. This paper presents their adaptation to Spanish. Structure, innovations included in the Spanish version, and the standardisation process are described, and some results obtained from the analysis of a sample of 1150 children are presented. The advantages and limitations of the use of parental report inventories are highlighted. For children before three years of age, there are very few assessment tools of language and communicative development with sufficient guarantees produced and edited in Spain. The Spanish version of the MacArthur-Bates Inventories represents an important contribution for early identification of language delays or disorders, and for follow-up of these cases.     

Subjective social status, objective socioeconomic status, and cardiovascular risk in women.

OBJECTIVE: Subjective perceptions of personal social status may relate to health beyond the effects of objective socioeconomic status (SES). The authors examined the relationship between subjective social status (SSS) and psychosocial, behavioral, and physical cardiovascular risk factors in middle-aged women. DESIGN: Ninety-two women (90.2% White) completed ladder-based, pictorial self-report measures of SSS relative to others in their community and in the United States. Psychosocial measures of depression, anxiety, pessimism, stress, and social support and behavioral risk factors of fruit and vegetable consumption, leisure physical activity, and body-mass index were obtained. In addition, women underwent measurement of clinic blood pressure and assessment of daytime ambulatory systolic and diastolic blood pressure (SBP; DBP) over 2 consecutive days. RESULTS: Community SSS was significantly inversely related to anxiety, pessimism, stress, and daytime ambulatory DBP after controlling for objective SES and U.S. SSS. Women with lower U.S. SSS showed less healthy dietary and exercise behaviors and, contrary to predictions, lower clinic and ambulatory DBP. CONCLUSION: This study provides additional evidence that perceptions of one's position in the social hierarchy could have important health implications beyond the impact of objective SES. Further, the cardiovascular risk implications of perceived community versus U.S. social status appear to be distinct.
