Gender and the Internet: Women Communicating and Men Searching

This research examined gender differences in Internet use and factors responsible for these differences. A sample of 630 Anglo American undergraduates completed the Student Computer and Internet Survey that contained questions about e-mail and Web use, and about potential affective and cognitive mediators of use. Based on a general model of Internet use, we predicted and found that females used e-mail more than did males, males used the Web more than did females, and females reported more computer anxiety, less computer self-efficacy, and less favorable and less stereotypic computer attitudes. Path analysis to identify mediators of gender differences in Internet use revealed that computer self-efficacy, loneliness, and depression accounted in part for gender differences, but that gender continued to have a direct effect on use after these factors were considered. Implications for realizing the democratizing potential and benefits of Internet use are discussed.     

Church-Based Social Support and Religious Coping

The purpose of this study is twofold: to explore the nature of church-based social support, and to see whether support received in religious settings is related to the use of religious coping methods. The data come from a nationwide survey of members of the Presbyterian Church USA. Three dimensions of religious support are examined in detail: emotional support from church members, spiritual support from church members, and emotional support from the pastor. These dimensions of support are used to evaluate an issue that has been largely overlooked in the literature—the relationship between religious support and religious coping. The findings reveal that people are especially inclined to use positive religious coping responses when they receive spiritual support from church members. Even though emotional support from the pastor also increases the use of religious coping methods, the relationship is not as strong. Finally, emotional support from church members has no effect.     

Metamorphosis: Essence, appearance, and behavior in the categorization of natural kinds

The transformation paradigm (Rips, 1989) was used to contrast causal homeostasis and strict essentialist beliefs about biological kinds. Participants read scenarios describing animals that changed their appearance and behavior through either accidental mutation or developmental maturation and then rated the animals on the basis of similarity, typicality, and category membership both before and after the change. Experiment 1 in the present study replicated the dissociation of typicality and categorization reported by Rips (1989) but also revealed systematic individual differences in categorization. With typicality and membership ratings collected between participants, however, Experiment 2 found no evidence for the dissociation and few essentialist responders. In Experiment 3, excluding information about offspring led most participants to categorize on the basis of appearance and behavior alone. However, with offspring information included and with questioning focused on the change of kind, essentialist categorization was still surprisingly rare. We conclude that strict essentialist categorization in the transformation task is relatively rare and highly task dependent, and that categorization is more commonly based on causal homeostasis.     

Making children gesture brings out implicit knowledge and leads to learning

Speakers routinely gesture with their hands when they talk, and those gestures often convey information not found anywhere in their speech. This information is typically not consciously accessible, yet it provides an early sign that the speaker is ready to learn a particular task (S. Goldin-Meadow, 2003). In this sense, the unwitting gestures that speakers produce reveal their implicit knowledge. But what if a learner was forced to gesture? Would those elicited gestures also reveal implicit knowledge and, in so doing, enhance learning? To address these questions, the authors told children to gesture while explaining their solutions to novel math problems and examined the effect of this manipulation on the expression of implicit knowledge in gesture and on learning. The authors found that, when told to gesture, children who were unable to solve the math problems often added new and correct problem-solving strategies, expressed only in gesture, to their repertoires. The authors also found that when these children were given instruction on the math problems later, they were more likely to succeed on the problems than children told not to gesture. Telling children to gesture thus encourages them to convey previously unexpressed, implicit ideas, which, in turn, makes them receptive to instruction that leads to learning.     

Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless of the character of the second task. In the second, the procedure was the same except that it included a high performance standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions, reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined to relevant cognitive performance realms.

Religious Doubt and Mental Health Across the Lifespan

The current study examined the connections among religious doubt, mental health, and aging in a nationwide sample of individuals 18 years and older (N = 1629). Findings indicate that that religious doubt emerging from the recognition of suffering and evil in the world has a deleterious impact on mental health. Results also show that as people grow older, religious doubts continue to be associated with psychopathology, but the magnitude of this association becomes weaker across age categories. In other words, the impact of doubt on mental distress declines as one ages. These effects were found across various measures of mental distress, including depression, general anxiety, interpersonal sensitivity, paranoia, hostility, and obsessive-compulsive symptoms. Findings are explored within the context of psychosocial development and the experiential trajectory of religious maturity.     

Using vision and dynamic touch to perceive the affordances of tools

The information that people use to perceive whether a tool is suitable for a certain task depends on what is available at a given time. Visually scanning a tool and wielding it each provide information about the functional attributes of the tool. In experiment 1, we investigated the relative contributions of vision and dynamic touch to perceiving the suitability of various tools for various tasks. The results show that, when both vision and dynamic touch are available, the visual information dominates. When limited to dynamic touch, ratings of suitability are constrained by the inertial properties of the tool, and the inertial properties that are exploited depend on the task. In experiment 2, we asked whether the manner in which a tool is manipulated in exploration depends on the task for which it is being evaluated. The results suggest that tools are manipulated in ways that reflect intentions to perceive particular affordances. Exploratory movements sometimes mimic performatory movements.
