Stuttering following brain damage

This paper describes the neurological, language, and speech status of seven brain-damaged patients with symptoms of cortical stuttering. We compare data from our seven patients to data presented on other brain-damaged stutterers, review theories of cortical stuttering's etiology, advance alternative hypotheses about mechanisms underlying such dy sfluencies, and compare cortical stuttering to stuttering in childhood.     

Image of God and Community Volunteering among Religious Adherents in the United States

Individual theological beliefs provide important motivations for religious people to volunteer in their communities. Compassion and loving one’s neighbor are both ideas that can motivate individuals to volunteer their time and talents. Religious believers who have conservative theological beliefs may see volunteering for their communities as a minor factor in their religious calling. Recent research on the role of social embeddedness within religious communities, however, has questioned the importance of theology as a motivation to volunteer (Putnam and Campbell, in American Grace. Simon and Schuster, New York, 2010; Lewis et al., in Soc Sci Res 42: 331–346, 2013). In this paper we test the effects of a religious adherent’s image of God’s disposition toward the world on their pattern of community volunteering. Using data from the 2005 Baylor Religion Survey and multinomial logit models, we find that having an image of God as judgmental lowers the odds that religious adherents report having volunteered for the community independent of their place of worship. Adherents who are most willing to engage the external community independent of a place of worship are those with less judgmental images of God. We also find that embeddedness is associated with volunteering for and with the place of worship in the community. Implications for theory, research and social capital formation are discussed.     

Optimizing assurance: the risk regulation system in relationships

A model of risk regulation is proposed to explain how people balance the goal of seeking closeness to a romantic partner against the opposing goal of minimizing the likelihood and pain of rejection. The central premise is that confidence in a partner's positive regard and caring allows people to risk seeking dependence and connectedness. The risk regulation system consists of 3 interconnected "if--then" contingency rules, 1 cognitive, 1 affective, and 1 behavioral. The authors describe how general perceptions of a partner's regard structure the sensitivity of these 3 "if--then" rules in risky relationship situations. The authors then describe the consequences of such situated "if--then" rules for relationship well-being and conclude by integrating other theoretical perspectives and outlining future research directions.     

The impact of competition on intrinsic motivation and creativity: considering gender, gender segregation and gender role orientation

The present research investigated whether competition influences children's artistic creativity and intrinsic motivation toward an art activity. Study 1 tested the hypothesis that boys' creativity would be enhanced by competition, while girls' creativity would be undermined. Fifty children (aged 6–10) made paper collages in one of two conditions; half competed for prizes and half did not. Results supported our hypotheses, and further showed that when children self-segregated by gender, the impact of competition was much more pronounced. Study 2 was designed to clarify the unexpected gender-segregation finding from Study 1. The Children's Sex Role Inventory [Boldizar, J.P. (1991). Assessing sex typing and androgyny in children: the Children's Sex Role Inventory. Developmental Psychology, 27, 505–515] was administered to 143 children (aged 6–11). One week later, these children made paper collages in one of four conditions; in addition to manipulating competition, assigned seating ensured that half of children were segregated by gender and half were not. Following the collage activity, an intrinsic and extrinsic motivation questionnaire was administered. Masculine children reported higher levels of intrinsic motivation when competing and when segregated by gender; they also reported higher levels of extrinsic motivation, especially when segregated by gender. These findings demonstrate that gender role is an important factor in determining children's responses to competition.     

Feature-based attention across saccades: Pop-out in color search is spatiotopic

Our perception of the world remains stable despite the retinal shifts that occur with each saccade. The role of spatial attention in matching pre- to postsaccadic visual information has been well established, but the role of feature-based attention remains unclear. In this study, we examined the transsaccadic processing of a color pop-out target. Participants made a saccade towards a neutral target and performed a search task on a peripheral array presented once the saccade landed. A similar array was presented just before the saccade and we analyzed what aspect of this preview benefitted the postsaccadic search task. We assessed the preview effect in the spatiotopic and retinotopic reference frames, and the potential transfer of feature selectivity across the saccade. In the first experiment, the target and distractor colors remained identical for the preview and the postsaccadic array and performance improved. The largest benefit was observed at the spatiotopic location. In the second experiment, the target and distractor colors were swapped across the saccade. All responses were slowed but the cost was least at the spatiotopic location. Our results show that the preview attracted spatial attention to the target location, which was then remapped, and suggest that previewed features, specifically colors, were transferred across the saccade. Furthermore, the preview induced a spatiotopic advantage regardless of whether the target switched color or not, suggesting that spatiotopy was established independently of feature processing. Our results support independent priming effects of features versus location and underline the role of feature-based selection in visual stability.     

Examining the Impact of Technology on Exhibitionistic Behavior

Contemporary sexual behavior cannot be fully understood without considering the effects of smartphones and social networking websites, both of which have provided additional avenues for consensual sexual activity. However, technology has also created new ways to engage in deviant behavior that may be similar to exhibitionism (exposing one’s genitals to unsuspecting individuals). Participants completed a survey about traditional exhibitionistic behaviors (flashing) and technological sexual behaviors such as sending sexually explicit pictures. A small percentage of participants reported engaging in both technological and traditional exhibitionistic behavior, which may be indicative of an electronic manifestation of deviant sexual behavior.
