Having a “senior moment”: Induced aging phenomenology, subjective age, and susceptibility to ageist stereotypes

The current research develops methods to experimentally manipulate subjective age in midlife and older adulthood to test whether subjective age moderates the effects of ageist stereotypes on a person’s well-being and expression of age-stereotypic social attitudes. Study 1 manipulates experiences of visual disfluency to test whether participants feel older when they experience unexplained visual disfluency. Study 2 crosses this fluency manipulation with a manipulation of the valence of primed aging stereotypes to test whether participants feel worse about themselves when they are primed with negative aging stereotypes and given an experience of unexplained visual disfluency. Study 3 tests whether participants express more age-stereotypic social attitudes when they are made to feel older through an experience of generation gaps and they are presented with evidence confirming the stereotype linking older age with psychological rigidity. These findings illuminate the phenomenological sources of variation in subjective age and suggest that subjective age influences adults’ susceptibility to ageist stereotypes.     

Aging attitudes moderate the effect of subjective age on psychological well-being: evidence from a 10-year longitudinal study

Older subjective age is often associated with lower psychological well-being among middle-aged and older adults. We hypothesize that attitudes toward aging moderate this relationship; specifically, feeling older will predict lower well-being among those with less favorable attitudes toward aging but not those with more favorable aging attitudes. We tested this with longitudinal data from the National Survey of Midlife Development in the United States-II assessing subjective age and psychological well-being over 10 years. As hypothesized older subjective age predicted lower life satisfaction and higher negative affect when aging attitudes were less favorable but not when aging attitudes were more favorable. Implications and future research directions are discussed.     

Predicting intention to use condoms in homosexual men: An application and extension of the theory of reasoned action

Abstract

A questionnaire based on the Theory of Reasoned Action was developed and tested to identify predictors of intention to use condoms. The questionnaire consisted of three original components: Behavioral Intentions, Attitudes and Subjective Normative Beliefs, and a new component, Behavioral Norms. Age of HIV antibody status were also collected. Internal consistency of the four components of the questionnaire was high: Cronbach's alpha coefficients ranged from 0.76 to 0.87. Logistic modelling identified the significant predictors of intentions to use a condom as Attitudes (Odds Ratio = 2.7, 95% CI 1.80?4.06, P < 0.001) and Behavioral Norms (Odds Ratio = 1.49,95% CI 1.06?2.11, P = 0.03). Contrary to the theory that demographic variables are not important predictive variables of intention, HIV antibody positive status and age were found to directly influence Behavioral Intentions to use a condom. About 50% of men older than 25 years of age intended to use a condom, irrespective of HIV status. Overall, 59% of men 25 years of age and younger intended to use a condom, but the percentage was affected by HIV status; 22% in men who were HIV positive and 63% in men who were HIV negative. These findings indicate that after modification, to include HIV antibody status, Age and Behavioral Norms, the Theory of Reasoned Action can identify significant predictors of intention to use a condom.     

Negative Numbers are not yet Automatically Associated with Space in 6th Graders

ABSTRACT

The metaphor of the mental number line accounts for numerous empirical effects of spatial-numerical associations. In the present study, we aimed at investigating directional spatial-numerical associations reflected by SNARC-like digit-direction and sign-direction congruency effects as well as the sign-digit compatibility effect when 6^th graders performed magnitude comparisons of multi-symbol numbers (i.e., positive and negative numbers). As spatial-numerical associations were associated with sensorimotor experiences, we used whole-body and finger tapping responses to manipulate the extent of motor responses. We only observed a SNARC-like digit-direction congruency effect, but neither a sign-direction congruency nor a sign-digit compatibility effect. This indicates that 6^th graders may already have developed spatial-numerical associations for absolute number magnitude, but not yet for polarity signs. Furthermore, not observing a sign-digit compatibility effect seemed to suggest that 6^th graders may not yet process multi-symbol numbers in the same parallel componential way as adults do. We argue that while 6^th graders are able to process negative numbers, they are not yet automatically associated with space or integrated in the place-value structure of the Arabic number system like multi-digit numbers are at this age.     

中小学普通教室自然光、白炽灯、萤光灯课桌面照度的研究

问 题 关于中小学普通教室的照度水平问题,近年来我国学者从保护视力的角度出发,曾作了不少有益的探讨。张国栋建议,教室人工照明最低照度可定为50勒;朱文思认为,教室人工照明的照度应高于50勒;胡瑞荣建议教室白炽灯的平均照度应以75勒为宜。这些研究多半是关于教室的人工照明方面的问题,至于不同光源,特别是对自然光的不同照度水平,对学生视觉功能影响的问题,较系统的研究尚不多见。     

Predicting intention to use condoms in homosexual men: an application and extension of the theory of reasoned action

A questionnaire based upon the Theory of Reasoned Action was developed and tested to identify predictors of intention to use condoms. Behavioral intentions, attitudes and subjective normative beliefs, behavioral norms, and age of HIV-positive status were included on the questionnaire. Internal consistency of the four components was high, with Cronbach's alpha coefficients of 0.76-0.87. Qualitative data were collected over 2 months from 194 homosexual men who participated in Sydney's homosexual community. Participants aged 17-64 years of mean age 29.5 attended individual interviews or small focus groups to discuss their views concerning condom use. 15% reported having tested HIV-positive, 59% tested negative, and 26% reported not knowing their HIV serostatus. According to logistic modeling, the significant predictors of intentions to use a condom were attitudes and behavioral norms, while HIV antibody positive status and age directly influence behavioral intentions to use a condom. About 50% of men over age 25 years intended to use a condom, irrespective of HIV status. Overall, 59% of men aged 25 years and younger intended to use a condom; 22% of HIV-positive men and 63% of HIV-negative men.     

Effect of interpolated extinction after partial delay of reward training on subsequent reacquisition and extinction

Four groups of albino rats were run four trials a day in a straight runway for 44 days. On the first 15 days, two groups were given continuous immediate reward (IR) and two groups a 50 per cent, schedule of 30-sec. partial delay of reward (PDR). On the next 15 days, one IR group and one PDR group were extinguished, while the other IR and PDR groups remained on their original schedules. In the third phase, all groups received 8 days of training on IR. Finally, all groups were given 6 days of extinction training. In the first extinction, PDR produced greater resistance to extinction than IR. In the second extinction period, the PDR group which had previously been given extinction and the two IR groups extinguished relatively rapidly and at approximately the same rates, while the PDR group which had not been extinguished was significantly more resistant to extinction than the other three groups.     

Functional neuroanatomy of the cognitive process of mapping during discourse comprehension

We used functional magnetic resonance imaging (fMRI) to identify brain regions involved in the process of mapping coherent discourse onto a developing mental representation. We manipulated discourse coherence by presenting sentences with definite articles (which lead to more coherent discourse) or indefinite articles (which lead to less coherent discourse). Comprehending connected discourse, compared with reading unrelated sentences, produced more neural activity in the right than left hemisphere of the frontal lobe. Thus, the right hemisphere of the frontal lobe is involved in some of the processes underlying mapping. In contrast, left-hemisphere structures were associated with lower-level processes in reading (such as word recognition and syntactic processing). Our results demonstrate the utility of using fMRI to investigate the neural substrates of higher-level cognitive processes such as discourse comprehension.
