Perceptions of physical and psychological aggression in close relationships: A review

This review of the literature examines the effect of contextual variables (i.e., characteristics of the perpetrator and victims, observer characteristics) on perceptions of physical and psychological aggression in close relationships. Observers view physical aggression as more serious, harmful, abusive, and more deserving of punishment than psychological aggression, male aggression as more serious than female aggression, and aggression in committed, exclusive relationships as more serious than aggression in casual ones. Victims of psychological aggression, however, perceive it as more harmful than physical aggression and consider the effects to be longer-lasting. The disparity between observer and victim perceptions of physical and psychological aggression extends to mental health professionals, who tend to judge the severity of aggressive behaviors based on frequency and duration of the actions instead of perpetrator intent. This difference of opinion may influence the reporting of and intervention in physically or psychologically aggressive situations, and how these types of aggression are treated by legal professionals, especially if those legal professionals are informed about aggressive romantic relationships by third-party observers whose opinions of the situation differ from those of the victims.     

One-month-old human infants learn about the social world while they sleep

Although infants display preferences for social stimuli early in their lives, we know relatively little about the mechanisms of infant learning about the social world. In the current set of studies, 1-month-old infants underwent an adapted eyeblink conditioning paradigm to examine learning to both 'social' and non-social cues. While infants were asleep, they were presented with either a 'social' stimulus (a female voice) or one of two non-social stimuli (tone or backward voice) followed by an airpuff presented to the eyelid. Infants in the experimental groups displayed increased learning across trials, regardless of stimulus type. However, infants conditioned to the 'social' stimulus showed increased learning compared to infants conditioned to either of the non-social stimuli. These results suggest a mechanism by which learning about the social world occurs early in life and the power of ecologically valid cues in facilitating that learning.     

Aggression as One Response to Conflict1

This paper presents two studies that explore the link between self-reported conflict management strategies and aggression. It was predicted that conflict strategies involving concern for the needs of the other would be inconsistent with aggressive behavior. On the other hand, conflict strategies that involve coercion and domination were predicted to be positively related to aggressive behavior. Studies using self-report and behavioral measures of aggression provide support for these predictions.     

Blaming Drunk Victims: Is It Just World or Sex Role Violation?

Richardson and Campbell (1980, 1982), in studying attributions of blame and responsibility for violent interactions, found that intoxicated victims were blamed more and held more responsible for their victimization than their sober counterparts. Two alternative explanations were proposed to account for this finding: the just world hypothesis and the effects of sex role violation. The present study was designed to test these explanations. One hundred twenty-nine males and 93 females read scenarios that varied the sex of the victim and the level of intoxication of the victim and the aggressor. Participants rated the responsibility of the aggressor, victim, and situation for the action and evaluated the aggressor and victim. Although strong support for neither of the hypotheses was demonstrated, more support was found for the effect of sex role violation than for the just world hypothesis.     

Developmental and sex-related differences in preschoolers' affective decision making

This study investigated developmental and sex-related differences in affective decision making, using a two-deck version of Children's Gambling Task administered to 3- and 4-year-old children. The main findings were that 4-year-old children displayed better decision-making performance than 3-year-olds. This effect was independent of developmental changes in inductive reasoning, language, and working memory. There were also sex differences in decision-making performance, which were apparent only in 3-year-old children and favored girls. Moreover, age predicted awareness of task and the correlation between the latter and decision-making performance was significant, but only in 4-year-old children. This study thus indicates that there is a remarkable developmental leap in affective decision making, whose effects are apparent around the age of 4, which according to our results, also marks the age when the correlation of declarative knowledge and decision-making performance becomes significant.     

Convergent and discriminant validity of the Taylor and Buss measures of physical aggression

Although the Taylor and Buss paradigms have been the most widely used measures of human physical aggression, few attempts have been made to establish validity of the measures. The present investigation attempted to demonstrate convergent and discriminant validity of the paradigms. Fifty-five males engaged in five tasks designed to measure helping, competition, and aggression. Correlations computed among these measures lend support for convergent and discriminant validity of the Taylor and Buss paradigms.     

Intimate Partner Violence, Welfare Receipt, and Health Status of Low-Income African American Women: A Lifecourse Analysis

Although the association among intimate partner violence (IPV), welfare receipt, and health status has been well-established, little is known about the temporal sequencing of these events. In a random sample of low-income African American women in an urban Midwestern county, lifecourse data about IPV and welfare receipt were obtained using the Life History Calendar method (D. Freedman, A. Thornton, D. Camburn, D. Alwin, & L. Young-DeMarco, 1988), along with data about mental and physical health status. Controlling for relevant factors, longitudinal analyses found that previous experience of IPV increased women's odds of receiving welfare benefits in a given year, but previous welfare receipt did not. Cumulative IPV, but not cumulative welfare receipt, was associated with current and past-year health problems. These findings are consistent with the hypothesis that IPV leads women to turn to welfare assistance, and that compromised physical and mental health due to past cumulative IPV interferes with women's gainful employment.     

Love attitudes and relationship experience

The present study examined the association of love attitudes with the initiation, maintenance, and dissolution of relationships. Respondents completed the Love Attitudes Scale and a questionnaire designed to measure experiences at each stage of relationship development. Ludus was relevant to all stages of relationship development; ludic attitudes were associated with absence of concern for partner loyalty, short and uncommitted relationships, and positive feelings about relationship dissolution. Pragma was associated primarily with relationship initiation (i.e., selection of an appropriate partner). Agape and Mania were most apparent during maintenance, as evidenced by relationships with indicators of involvement and loyalty. Agape, Mania, and Eros related to negative emotions at the point of relationship dissolution.     

Review Article: Chiari Type I Malformation with or Without Syringomyelia: Prevalence and Genetics

Chiari type I malformation has traditionally been defined as a downward herniation of the cerebellar tonsils of 5 mm through the foramen magnum and it is likely associated with a volumetrically reduced posterior fossa. Syringomyelia is commonly associated with Chiari type I malformation. We estimate the prevalence of these two conditions and determine that they are more common than previously expected. We identify the genetic syndromes associated with some cases of Chiari type I malformation, and we provide evidence in favor of a genetic hypothesis for at least a subset of the nonsyndromic cases.
