Changes in Physiological Stress and Self-Reported Mood in Younger and Older Adults After Exposure to a Stressful Task

ABSTRACT

The objective of the current study was to compare the trajectories of physiological levels of stress and self-report measures of mood in younger and older adults and to examine how a stress induction would affect performance. The current study examined physiological and subjective indicators of stress and mood before, mid-way through, and after being exposed to a stressful computer task. Stress levels and negative affect increased after stress induction relative to levels before and after the stressful task. Practice on the task helped to improve performance (accuracy and reaction time) but high workload measured during the task mitigated accuracy in younger and older adults, whereas it enhanced response speed in younger adults.     

Positive illusions about a partner’s personality and relationship quality

Previous studies have shown individuals to hold positive biases about their relationships. The present study examined positive illusions about a partner’s specific personality characteristics in relation to relationship quality and personality. Both partners of 120 heterosexual couples participated in the present study, making it possible to examine both partner and actor effects. Results showed that although, in general, individuals did not hold positive illusions about a partner’s specific personality characteristics, positive illusions were positively related to relationship quality. In addition, interesting relations emerged between positive illusions about a partner’s personality and both individuals’ personality and marital duration.     

Linda Stein??s ??Fluidity of Gender?? (2009?C2010)

Linda Stein??s recent sculptures are abstracted human figures tightly encased in black leather. Some hang on the wall, some are free standing; all are headless, armless, and have truncated legs. The scavenged leather ??skin?? is old jackets and bags that reveal their original uses in the embossing, zippers, and buckles that Stein uses for textural accents. This paper will survey the new work??s claim, as stated in the exhibition title, to represent the ??Fluidity of Gender.?? The tactile nature of the medium itself prompts certain questions about the role sensuality plays in gendered experience, and how sexuality and power are intertwined. The distressed surfaces of the sculptures suggest the paramount significance of experience as contributing materially to body image. In conclusion, this essay will explore the way representations of bodies whose gender is unfixed may influence the viewer??s body image.     

Biculturalism and Academic Achievement of African American High School Students

Biculturalism was examined as a factor that may positively affect the academic achievement of African American high school students, beyond cultural identity and self‐esteem. Hierarchical regression analyses determined that cultural identity and academic self‐esteem were important factors for academic achievement, but not biculturalism. Implications and future research are discussed. Se examinó el biculturalismo como un factor que puede afectar positivamente al rendimiento académico de los alumnos de educación secundaria Afroamericanos, más allá de la identidad cultural y la autoestima. Los análisis de regresión jerárquica determinaron que la identidad cultural y la autoestima académica fueron factores importantes para el rendimiento académico, pero no el biculturalismo. Se discutieron implicaciones e investigaciones futuras.     

Activation During Observed Parent–Child Interactions with Anxious Youths: A Pilot Study

Parent–child interaction paradigms are often used to observe dysfunctional family processes; however, the influence of such tasks on a participant’s level of activation remain unclear. The aim of this pilot project is to explore the stimulus value of interaction paradigms that have been commonly used in child anxiety research. Twenty-nine parent–child dyads with clinically anxious (n = 16) and non-anxious (n = 13) youths engaged in a series of tasks (threat and non-threat) used in previous studies of parenting and youth anxiety. Heart rate (HR) data, as an indicator of physiological activation, were collected across tasks, and participants rated the perceived representativeness of their interactions in the laboratory to their usual behavior at home. Significant HR changes were observed for both parent and child. Change in child HR from baseline to non-threat task was smaller than change in HR from baseline to threat tasks. Change in parent HR from baseline to ambiguous situations tasks was smaller than changes from baseline to other threat tasks. Differences in HR change between anxious and non-anxious children were explored. Participants rated laboratory interactions as similar to those experienced in the home. Results suggest that presumably emotionally-charged discussion tasks may produce increased activation compared to tasks that were designed to be more neutral. Implications for future research and limitations are discussed.     

Who’s Afraid of the Big Bad Wind? Origins of Severe Weather Phobia

Natural Environment phobia include fears cued by events such as severe weather. Given the limited research in this area, the present study sought to assess the prevalence and learning history origins of these fears, as well as their relation to anxiety sensitivity (AS). Study One participants included 533 (66%F) undergraduates who completed the Weather Experiences Questionnaire. Overall, 42?% reported exposure to a severe weather event (e.g., hurricanes); 16?% reported high- and 44?% low-fear about weather. Thirty-three from each group participated in Study Two, wherein one high-fear participant approximated the diagnostic criteria for severe weather phobia. High-fear participants cited direct conditioning (43?%) followed by vicarious conditioning (39?%) as the most common learning pathways. The remaining18% could not recall the source of their fear and none identified operant conditioning. One-third cited mothers (versus 8?% fathers) as sharing similar fears. Most had not witnessed parents hurt, frightened, or distressed by severe weather but claimed parents had warned them about severe weather. High- (vs. low-) fear participants revealed more AS-somatic versus AS-cognitive or AS-social concerns. The importance of such research in light of the increasing frequency of severe weather events is discussed.     

Play as co‐created narrative in computer game consumption: The hero's journey in Warcraft III

Computer games are now a significant consumption activity in consumer culture. Informed by interdisciplinary studies and drawing on data from in‐depth interviews with players of the Warcraft III computer game, we explore the relationship between play and storytelling during digital play. Understanding that such play is determined by systems of game rules and that computer game characters and settings are capable of conveying cultural meanings to players, we found that the rules of play in computer games can be designed in ways that encourage consumers to co‐create meaningful story plots derived from their knowledge of myth and fiction. In the case of Warcraft, these plots resembled the archetypal plot of the hero's journey. We conclude that computer games immerse consumers in a form of playful consumption that engages them in memorialised, co‐authored storytelling. Copyright © 2012 John Wiley & Sons, Ltd.     

Least-squares theory based on general distributional assumptions with an application to the incomplete observations problem

The linear regression modely=x+ is reanalyzed. Taking the modest position that x is an approximation of the best predictor ofy we derive the asymptotic distribution ofb andR ², under mild assumptions.The method of derivation yields an easy answer to the estimation of from a data set which contains incomplete observations, where the incompleteness is random.     

Is Parent-Offspring Conflict Sex-Linked? Freudian and Darwinian Models

Freud's Oedipal theory sees parent-offspring conflict as a within-gender rivalry, whereas most modern evolutionary models interpret it as a gender-blind disagreement about resource allocation. New analyses of family homicides and a critical review of prior evidence do not support the central Freudian claim of a same-sex contingency in parent-offspring antagonism during the Oedipal phase. Several errors of fact and interpretation in psychoanalytic theorizing about family relations are discussed. We argue that psychoanalysts mistake substantive conflicts between nonrelatives for symbolic manifestations of family conflicts.     

Gender in the college classroom: An assessment of the “chilly climate” for women

Previous research suggests that female students participate less often and less assertively than male students in college classrooms, and that teachers' discriminatory behaviors are partly responsible. Two in-class surveys of college students (N = 1375)—one at a university and one at a small college—assessed perceptions of student-teacher interaction. Factor analysis revealed a number of analytically distinct dimensions of classroom climate: what the class is like in general, what the class is like for the individual student, and what specific positive and negative teacher behaviors affect interaction. Class size affected each of these dimensions. Gender of student was significant only in the college survey, with males participating more, but this gender difference was not due to teachers' discrimination. Female teachers were more likely to create a participatory climate for all students. Creating a better classroom climate for female students creates a better learning environment for all students.We wish to thank Lawrence G. Rosenberg, Jean Dowdall, and Penelope J. Davis for their help and support during this research project.
