Masculine gender role stress and intimate abuse: Effects of gender relevance of conflict situations on men's attributions and affective responses.

This article proposes an approach to understanding mens abuse of their intimate partners. The authors suggest that the concept of masculine gender role stress (MGRS) might be useful in identifying men who are predisposed to become abusive with their intimate partners. College men who scored either high or low on an MGRS scale were assessed, and their attributions, affect, and conflict resolution behavior toward their intimate female partners were examined. Participants were presented with masculine-gender-relevant and masculine-gender-irrelevant vignettes involving disputes with their intimate female partners. Results indicated that men high in MGRS attributed greater negative intent; expressed more irritation, anger, and jealousy; and endorsed aggressive responding more often than did men low in MGRS. Implications of MGRS and masculine relevance of conflicts for understanding male abusive behavior are discussed.

Causal Attributions and Affective Responses to Provocative Female Partner Behavior by Abusive and Nonabusive Males

The present study examined the effects of the degree of female partner provocation on cognitive attributions and affective responses in verbally abusive and nonabusive college males. In Phase 1 (N = 116), subjects listened to audiotapes of hypothetical dating situations in which the female partners behavior was nonprovocative or moderately provocative; in Phase 2 (N = 105), the female partners behavior was nonprovocative or highly provocative. The major hypothesis was that abusive males would make greater negative intent and responsibility attributions and report more powerful feelings of jealousy, rejection, and abandonment in response to moderately and highly provocative partner behavior but not in response to nonprovocative partner behavior than would nonabusive males. Results from Phase 1 showed that abusive males reported reliably greater negative attributions and feelings of jealousy, rejection, and abandonment in response to moderately provocative partner behavior than did nonabusive males. No group differences were associated with nonprovocative partner behavior. Results from Phase 2 showed that abusive males attributed greater negative intent and feelings of rejection and abandonment to both highly provocative and nonprovocative partner behavior than did nonabusive males. Negative attributions and feelings of jealousy, rejection, and abandonment increased reliably from moderately provocative to highly provocative female behavior for abusive and nonabusive males, who differed reliably from each other. Implications for the assessment and treatment of abusive men were discussed.

Effects of deprivation on salivary flow in the apparent absence of food stimuli

Salivation performance in the absence of food-related stimuli was measured with an absorbent technique in 19 subject under no (0-1 h) and moderate (4-6 h) levels of food deprivation. Overall, salivation was reliably (p less than 0.05) greater the higher the hours of deprivation. Results also revealed a reliable positive correlation between hours of deprivation and subjective ratings of hunger. For subjects whose hunger ratings coincided with hours of deprivation, analysis of the salivation data yielded highly reliable (p less than 0.01) differences due to deprivation/hunger. For subjects who reported the same level of hunger at different hours of deprivation, there were no reliable differences in salivation due to deprivation.

Increasing the clinical yield of computerized tomography for psychiatric patients

Computerized tomography (CT) continues to be extensively utilized to exclude intracranial pathology in psychiatric practice, but little is known about clinical risk factors, which might predict those patients most likely to benefit from the procedure. We reviewed 150 cases of psychiatric patients who received CT scans to exclude intracranial pathology. We assessed the relationships of patient age, psychiatric diagnosis, and findings from neurologic and cognitive examinations to CT results that influenced patient care, and overall normal and abnormal CT results. Fifty-three percent of the CT scans were abnormal, 11% influenced patient care, and only 2% identified potentially reversible lesions. Cognitive exam results and, to a lesser extent, neurologic exam results, were sensitive predictors of CT findings that influenced patient care. All patients with clinically influential CT results had cognitive deficits and all but one had neurologic deficits. Patients older than 60 years of age and those with organic mental syndromes were most likely to have clinically influential CT findings. Our results suggest that utilizing specific clinical risk factors such as findings from clinical examinations, patient age, and psychiatric diagnosis, to guide the ordering of CT scans, can greatly increase the yield of the procedure for psychiatric patients, without excess medical morbidity.

Effects of pretraining on conditioning-enhanced neophobia: Evidence for separable mechanisms of neophobia and aversion conditioning

In two experiments, rats (n = 228) received pretraining access to a distinctive novel flavor (saline) followed by aversion conditioning to a different novel conditioned stimulus (CS) (saccharin). Then the rats were tested for aversion to the CS (saccharin) or for conditioning-enhanced neophobia to a third novel flavor (casein hydrolysate). Pretraining access to a distinctive novel flavor that differed from the CS reliably reduced the magnitude of conditioning-enhanced neophobia to casein, but did not reliably affect conditioned aversion effects to the CS. Pretraining access to the CS reduced aversion effects to the CS and reduced postconditioning neophobia to casein to the performance level shown by ingestion-toxin controls. Results were consistent with the view (Braveman & Jarvis, 1978) that conditioned aversion and neophobia may be independent phenomena with separable underlying mechanisms.

Aversion conditioning and enhanced neophobia: role of test stimuli.

In Experiment 1, 100 rats (Rattus norvegicus) received 10% sucrose or 5% casein hydrolysate followed, after 10 min, by a LiCl or saline injection or, after 12 h, by a LiCl injection. Subsequently, rats received aversion testing to the CS or neophobia testing to the opposite novel flavor. Aversion effects were reliably greater to casein than to sucrose. However, conditioning with sucrose yielded a reliably greater increase in neophobia to casein (relative to controls) than conditioning with casein yielded to sucrose. In Experiment 2, 60 rats received distilled water followed, after 10 min, by LiCl or saline injection or, after 12 h, by LiCl injection. Aversion effects occurred to distilled water. Neophobia testing to casein and sucrose showed that, relative to controls, neophobia increased reliably more to casein. The results of Experiments 1 and 2 were not attributable to differences in baseline intakes between casein and sucrose flavors. Together, these experiments indicated that the demonstration of conditioning-enhanced neophobia may depend more on the characteristics of the neophobia test flavor than on the strength of aversion established because of CS characteristics.

Effects of preexposure flavor concentration on conditioned aversion and neophobia

In Experiment 1, 128 experimentally naive, water-deprived rats (Rattus norvegicus) received pretraining access to either 0.25 or 1.5% saccharin, distilled water, or 2.0% saline, followed either by a pairing of 0.25 or 1.5% saccharin with an intraperitoneal injection of 0.15 M lithium chloride (LiCl) or by a pairing of distilled water with LiCl. Preexposure to either saccharin concentration reliably reduced conditioned aversion effects to 0.25% saccharin, relative to that for preexposure to distilled water or saline. But only preexposure to 1.5% saccharin reduced aversion effects to that concentration. In Experiment 2, 48 naive, water-deprived rats received preexposure procedures as in Experiment 1. Afterwards, the rats were tested for neophobia to 0.25 or 1.5% saccharin. Neophobia was reliably greater to the 1.5% concentration. However, preexposure to either saccharin concentration obliterated evidence for neophobia to saccharin, relative to that following preexposure to distilled water or saline.

Persistence of response prevention effects following retraining of escape behavior

Abstract This study evaluated the effects of response prevention procedures on the extinction of escape behavior following the reinstatement of shock-escape training prior to the start of extinction. Female hooded rats were assigned to four groups ( N = 10) in a factorial design which orthogonally combined response prevention or pseudo-prevention procedures with escape retraining or no retraining procedures. Results showed that prevention reliably impaired shock-escape behavior on early retraining trials; but this effect dissipated completely by the end of retraining. In extinction, prevention reliably facilitated the extinction of escape behavior relative to that of pseudo-prevention controls; but the degree of facilitation was reliably attenuated by retraining procedures. These findings were related to the competing response interpretation of prevention effects.

Salience and the effects of CS preexposure on aversion conditioning

Rats (n = 84) received preexposure to distilled water or to one of two differently salient flavors, 5.0% casein or 10.0% sucrose, casein being the more salient. Each preexposure group then received aversion conditioning to a 5.0% casein or a 10.0% sucrose CS. Aversion effects were reliably more enduring to casein than to sucrose. Relative to water-preexposed groups, preexposure to casein attenuated aversion effects to the casein CS reliably less than preexposure to sucrose attenuated aversion effects to the sucrose CS. During preexposure, neophobia was reliably greater to casein than to sucrose, suggesting that the demonstration of salience in taste aversion learning may be based on the inherent aversive properties of novelty.

Effects of age and flavor preexposures on taste aversion performance

Rats (Rattus norvegicus) 19, 30, 90, and 180 days of age received one pairing of 12% sucrose (w/v) and an intraperitoneal (ip) injection (2% body weight) of either.15 M lithium chloride (LiCl) or.9% saline. Testing with a two-bottle choice procedure showed that, relative to saline-injected controls, aversion effects in LiCl groups increased with age at conditioning. In Experiment 2, 19- and 90-day-old rats received zero, one, or three exposures to 12% sucrose prior to pairing sucrose with an injection (ip) of.15 M LiCl or.9% saline. Testing with a two-bottle choice yielded reliably greater aversion effects for adult rats than for pups. However, both age groups showed reliably increasing attenuation of taste aversion with increasing preexposures.
