Salience of rape affects self-esteem: The moderating role of gender and rape myth acceptance

In two experiments, conducted in Germany and the U.S.A., it was found that exposure to a rape report lowered self-esteem and positive affect in women who do not accept ‘rape myths’ (stereotypical beliefs which blame the victim and exonerate the rapist; Burt, 1980). Men high in rape myth acceptance (RMA) showed an increase in positive affect and self-esteem as a function of exposure to rape; men low in RMA and women high in RMA were largely unaffected. Both experiments demonstrated that these effects were specific to rape, as opposed to violence in general. These results support the feminist hypothesis that the threat of rape serves the function to exert social control over women and to sustain men's dominance. Potential cognitive mechanisms mediating the observed effects are discussed.     

Semantic emphasis in causal sentences

A shift in emphasis can change the truth-value of a singular causal sentence. This poses a challenge to the view that singular sentences predicate a relation. I argue that emphasized causal sentences conjoin predication of a causal relation between events with predication of a relation of causal relevance between states of affairs (or perhaps facts). This is superior to the treatments of such sentences offered by Achinstein, Dretske, Kim, Sanford, Bennett, and Levin. My proposal affords clarity regarding logical structure, at least at a certain level of detail. It makes the relation between the content of an emphasized causal sentence and the unemphasized version clear. It answers some questions about the ontological requirements of the truth of emphasized causal sentences, without introducing new entities (as do some other accounts) or unacceptable consequences for identity and individuation of events.     

Maternal aggression: disruption by perioral anesthesia in lactating Long-Evans rats (Rattus norvegicus)

Role of perioral somatosensation in the display of maternal aggression in Long-Evans Norway rats (Rattus norvegicus) was investigated during early lactation by local anesthesia of the mystacial pads with lidocaine, which blocks conduction in the infraorbital nerve. Acute perioral anesthesia markedly reduced the likelihood that maternal aggression was expressed; this effect of perioral anesthesia was not ameliorated by a repeated test with the same treatment or by pretreatment fighting experience. The dams that fought with the intruder during perioral anesthesia did so after greatly increased sniffing contact and with decreased vigor compared with controls. Males that were attacked tended to freeze, whereas males that were not attacked were active. Thus, trigeminal afferents are critical for the initiation and normal execution of maternal aggression responses in Norway rats.     

The lost e-mail method: Milgram’s lost-letter technique in the age of the Internet

We examined Milgram’s (1977) lost-letter technique using e-mail. In the first experiment, 79 college faculty received mock lost e-mail messages. Nineteen percent of those who received the messages responded, in all cases by returning the message to the “sender” instead of forwarding it to the “recipient.” In the second study, attitudes toward presidential candidate Ross Perot were examined by sending out two different messages to 200 randomly selected e-mail addresses in the United States. Although there was no differential response rate, examination of content revealed attitudes consistent with concurrent poll data.     

Macro- and microlevel factors related to sense of community: The case of temporary neighborhoods in Israel

This study examines macro and micro factors influencing the development of sense of community (Davidson & Cotter, 1980) in two different populations (immigrants and veterans) in new temporary neighborhoods in Israel. At the macrolevel, the major factors examined were population size, population density, number of dwelling units in the site, urbanity of the area, ethnic heterogeneity, and peripheriality of the region. Three kinds of variables were examined on the microlevel: (a) personal attitudes: evaluation of the dwelling unit and satisfaction with public services; (b) social networks; and (c) sociodemographic characteristics. Data were collected from 242 immigrants from the former USSR and from 60 Israeli veterans, residing in 5 different sites. Two different patterns of predictors of sense of community emerged in the two different samples. In the veteran sample, only one macrolevel variable entered the stepwise analysis equation: the number of dwelling units in the site. In the immigrant sample, three significant microlevel factors entered the equation: evaluation of the dwelling unit, external network, and age. The data thus suggest that the major determinant factors underlying sense of community vary for different groups of people. The paper is based on a study initiated and financed by the Ministry of Housing and Construction, the Unit of Social Policy, Israel.     

Maternal stress and pituitary-adrenal manipulations during pregnancy in rats: effects on morphology and sexual behavior of male offspring.

The purpose of the present study was to determine whether the demasculinizing and feminizing effects of prenatal stress (i.e., stress applied to the mother during pregnancy) in rats reported previously are mediated by activation of the maternal pituitary-adrenal axis. Neither whole-body restraint, with or without hyperthermia, nor ACTH treatment during the last third of gestation had any reliable effect on masculine or feminine sexual behavior in male Sprague-Dawley offspring, although these treatments produced maternal pathology and evidence of maternal adrenocorticoid release. Significant littermate similarity was found for almost every morphological and behavioral measure. Failure to control for the litter variable may account for many previously reported effects of prenatal stress on sexual behavior in rats. The discrepancy between the present and earlier findings is discussed in terms of methodological and theoretical considerations.     

Attention to important versus trivial tasks and salience of fatigue-related symptoms for coronary prone individuals

The present study tested the hypothesis that individuals with the Type A coronary prone behavior pattern focus their attention more on important tasks, and less on trivial tasks than do Type B's. The study used a paradigm in which some subjects worked on math problems (important task) and rated intervening mood items (trivial task), whereas others rated mood items they were to memorize (important task) and worked on intervening math problems (trivial task). All subjects were later tested on recall of mood items. Results indicated that Type A's performed better on math problems and recalled more fatigue-related mood items when the task was important than when it was trivial; for Type B subjects, there was no difference in the number of math problems solved correctly or number of mood items recalled between important and trivial task conditions. Moreover, Type A's reported greater fatigue when mood recall was the important task than when math was the important task, whereas fatigue ratings of Type B's did not differ across these conditions. The findings suggest that Type A's suppress their attention to fatigue-related symptoms only when symptoms are not the objects of focus.     

Spacing judgments as an index of integration from context-induced relational processing: Implications for the free recall of ambiguous prose passages

The effect of information integration on the recall of ambiguous prose passages was investigated. In Experiment 1, subjects read ambiguous passages that were difficult to comprehend without titles. In judging the relative positions in the passages of pairs of test sentences, subjects performed better when they read passages headed by a suitable title than when they read untitled passages or received a title at the time of testing. In Experiment 2, subjects provided with a title at encoding also better discriminated complete old sentences from foils composed of fragments of two different old sentences than did subjects provided with no titles or with titles at the time of testing. These two tests index the degree of inter- and intrasentence information integration, respectively. Two findings indicated that integration affected free recall of an ambiguous passage. First, when the degree of integration of the passage's propositions was controlled, free recall of the passage was no different for subjects who did or did not know the passage's title at encoding. Second, inducing subjects to comprehend the passage's sentences individually, without relating them to one another, reduced free recall of the passage.
