Inferring sexual interest from behavioral cues: Effects of gender and sexually relevant attitudes

Research has found that men impute more sexual meaning to others' behavior than do women. However, little research has examined the possibility that men and women share perceptions of the sexual connotativeness of certain behaviors but diverge in their perceptions of other behaviors. In Study 1, 162 male and 186 female undergraduates, predominantly Caucasian, rated the degree to which each of 27 behaviors of male and female targets connoted a desire for sexual intercourse. Multivariate analyses of variance revealed that, whereas men perceived all but two of the female target behaviors more sexually than women, men and women differed in their perceptions of the sexual connotativeness of only about half of the male target behaviors. A factor analysis revealed three factors for both male and female target behaviors, reflecting mundane dating behaviors, romantic behaviors, and sexual behaviors. Relative to women, men perceived only the mundane dating behaviors more sexually, although regression analyses showed these effects to be moderated by subjects' attitudes toward women. Study 2 examined the extent to which sexually relevant attitudes (e.g., sex role stereotyping, adversarial sexual beliefs, and rape myth acceptance) moderate subjects' perceptions of the sexual connotativeness of the behaviors. Men, particularly those who endorsed traditional, sexually relevant attitudes, were more likely than women to impute sexual meaning to the behaviors. The implications of this for dating situations are discussed.The author wishes to thank Mark Leary and two anonymous reviewers for their comments and suggestions on earlier versions of this article.     

Dual-Element Effects in Pigeons’ Matching-to-Sample with Temporal and Visual Stimuli

The present study examined whether the dual-element effect occurs when temporal and visual stimuli appear simultaneously in a zero-delayed, symbolic matching-to-sample task. Two groups of pigeons were first exposed to either a red or green sample stimulus, for either 30 s or 5 s. The sample was followed by the presentation of yellow and blue comparisons. For pigeons in one group, the duration of the sample was the relevant cue. Responses to the yellow comparison were reinforced if the sample was 30 s, and responses to the blue comparison were reinforced if the sample was 5 s. For the other group, sample duration was irrelevant. Responses to the yellow comparison were reinforced if the sample had been green and responses to the blue comparison were reinforced if the sample had been red. Both groups then learned a second matching task in which the sample and comparison stimuli were vertical and horizontal lines. Finally, matching performance was examined when the lines appeared together with the temporal or color elements. The results showed that the line matching task was acquired more slowly for pigeons that were first trained to attend to duration. More importantly, matching was reduced when the temporal and line elements appeared simultaneously, and the effects were similar to those obtained when visual elements are combined.

     

A processing model for the analysis of one-way arguments in discourse

This paper describes a computational model for analyzing arguments in discourse. In particular, the model describes processes necessary for interpreting one uninterrupted argument from a speaker. The resulting output is a representation for the underlying claim and evidence relations between propositions of the argument. For our processing model we present: (i) a characterization of coherent orderings of propositions, used to limit search for interpretation of each new proposition (ii) a working definition of the evidence relation, used to recognize connections between propositions (iii) a theory of the function and use of clue words — special words and phrases indicating the structure of the argument — then used in the analysis to control search for interpretation and verification of evidence relations.     

Distraction,Control, and Dental Stress1

This study examined the efficacy of external distraction as a coping strategy. Thirty-eight dental patients were randomly assigned to one of three groups: incidental music during the dental procedure, music coupled with suggestions that music would help reduce stress, or a no-treatment control group. Patients in both music groups reported experiencing less stress (i.e., less pain. less discomfort, more control) than patients in the no-treatment group. Patient ratings made by dentists, blind to condition, provided converging evidence for the therapeutic effect of distraction. Thus, distracting music was found to be effective in reducing stress and increasing perceptions of control. The relative ease and simplicity of implementing external distraction compared to manipulating actual control in a medical setting may make this manipulation attractive to professionals involved with individuals experiencing stress.     

Age differences in the recall of actions and cognitive activities: The effects of presentation rate and object cues

Summary In studies of activity memory, age differences have been found in the recall of cognitive activities (sustained mental activities that subjects solve during acquisition) but not in recall of Subject-Performed Tasks (one-step actions that subjects enact during acquisition). To understand the reasons for the discrepant findings, both types of item were included in a study examining the effects of object cues, rate of presentation, and aging. Variations in presentation rate or use of objects did not account for the different findings on the two item types. Even when presentation rate and object cues were matched, larger age differences were found for recall of cognitive activities than of SPTs. Age differences were also affected by the interaction of item type, presentation rate, and the presence of objects during encoding. To identify the variables controlling age differences, more analysis is needed of the features of activities to be remembered.

A Puzzle Concerning Time Perception

According to a plausible and influential account of perceptual knowledge, the truth-makers of beliefs that constitute perceptual knowledge must feature in the causal explanation of how we acquire those beliefs. However, this account runs into difficulties when it tries to accommodate time perception – specifically perception of order and duration – since the features we are apparently tracking in such perception are (it is argued) not causal. The central aim of the paper is to solve this epistemological puzzle. Two strategies are examined. The first strategy locates the causal truth-makers within the psychological mechanism underlying time perception, thus treating facts about time order and duration as mind-dependent. This strategy, however, is problematic. The second strategy modifies the causal account of perceptual knowledge to include a non-causal component in the explanation of belief-acquisition, namely chronometric explanation. Applying this much more satisfactory approach to perceptual knowledge of time, we can preserve the mind-independence of order and duration, but not that of time's flow.     

The representation of majorities and minorities in the British press: a content analytic approach

A content analysis examined the way majorities and minorities are represented in the British press. An analysis of the headlines of five British newspapers, over a period of five years, revealed that the words ‘majority’ and ‘minority’ appeared 658 times. Majority headlines were most frequent (66% ), more likely to emphasize the numerical size of the majority, to link majority status with political groups, to be described with positive evaluations, and to cover political issues. By contrast, minority headlines were less frequent (34%), more likely to link minority status with ethnic groups and to other social issues, and less likely to be described with positive evaluations. The implications of examining how real‐life majorities and minorities are represented for our understanding of experimental research are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Neurobehavioral Correlates of Chronic Hepatitis C

Chronic infection with the hepatitis C virus is a major public health concern in the United States and worldwide, and persons with psychiatric histories are more likely to have chronic hepatitis C (CHC). Neurobehavioral consequences of CHC are common in all phases of the disease process and significantly contribute to morbidity. Antiviral treatment also is associated with neurobehavioral difficulties that can interfere with successful completion of treatment and result in fewer patients clearing the virus. Fatigue, depression, cognitive dysfunction, and anxiety are the most common neuropsychiatric symptoms reported by patients with CHC regardless of treatment status. Behavioral health care professionals can play a vital role in decreasing the personal and societal burden of CHC by being active members of the treatment team and by furthering knowledge of how to manage neurobehavioral correlates of CHC.
