Font tuning associated with expertise in letter perception

Font tuning (FT) occurs when observers recognize a sequence of letters presented in the same font faster than in different fonts (Sanocki 1987, 1988 Journal of Experimental Psychology. Human Perception and Performance 13 267-278; 14 472-480). Here, we test the hypothesis that FT is associated with expertise with a specific writing system. We developed a systematic search task allowing the measurement of FT over a large number of letters and generalized the finding of FT from English readers viewing Roman letters to Chinese readers viewing Chinese characters. Non-Chinese readers did not show evidence of FT for Chinese characters in this search task. We also used a simpler 3-letter identification task to directly compare novice and expert readers, and to explore FT for different aspects of font such as fill, slant, and aspect ratio. We found that experts tune to aspect ratio but not to the other font changes. These findings reveal that letters are not processed visually in the same manner as shapes, and suggest an explanation for the cortical specialization obtained in the visual system for letters.

Acts of Contrition,Forgiveness by God,and Death Anxiety Among Older Mexican Americans

The purpose of this study is to see if performing acts of contrition in order to be forgiven by God is associated with lower levels of death anxiety among older Mexican Americans. A conceptual model containing the following relationships was developed to evaluate this and other hypotheses: (a) It is hypothesized that older Mexican Americans who attend church more often will have a stronger sense of God-mediated control (i.e., the belief that God works together with people to attain desired goals and eliminate unwanted stressors), (b) individuals with a stronger sense of God-mediated control will be more likely to perform acts of contrition in order to earn God's forgiveness, (c) performing acts of contrition will enhance feelings of self-worth, and (d) a stronger sense of self-esteem will be associated with lower levels of death anxiety. Data from a nationwide sample of older Mexican Americans provide support for each of these relationships.     

Multiple hydrogen trapping at monovacancies

Novel structures for multiple hydrogen atoms trapped at a monovacancy are discussed. Using atomistic simulations based on semiempirical interatomic potentials and density functional theory, we find low-energy configurations for four, five, and six hydrogen atoms around a monovacancy different than those that have been previously studied in the literature. The energetics of hydrogen binding are compared to results, both theoretical and experimental, previously published in the literature. We argue that up to four hydrogen atoms may be exothermically bound to monovacancy.     

Dynamic orientation cues decrease the viewpoint cost of mental rotation

Mental rotation, as a covert simulation of motor rotation, could benefit from spatial updating of object representations. We are interested in what kind of visual cue could trigger spatial updating. Three experiments were conducted to examine the effect of dynamic and static orientation cues on mental rotation, using a sequential matching task with three-dimensional novel objects presented in different views. Experiment 1 showed that a rotating orientation cue with constant speed reduced viewpoint costs in mental rotation. Experiment 2 extended this effect with a varied-speed rotating orientation cue. However, no such benefit was observed with a static orientation cue in Experiment 3. These findings indicated that a visually continuous orientation cue is sufficient to elicit spatial updating in mental rotation. Furthermore, there may be differences in the underlying mechanisms of spatial updating on the basis of constant-speed rotating cues and varied-speed rotating cues.     

Trajectories of change in dimensions of forgiveness among older adults and their association with religious commitment

Forgiveness is a complex construct with an important role in religious traditions worldwide, and is associated with mental and physical health outcomes. This seven-year longitudinal study examined changes within individuals during, and differences based on birth cohort, in forgiveness during late life. Growth curve analysis was used to analyse the general pattern of change across the course of older adulthood in eight dimensions related to forgiveness. Increases over time were observed in forgiveness of others, conditionality of forgiveness of others, forgiveness of self, feelings of being forgiven by God, and feelings of being forgiven by others. Decreases over time were observed in difficulty forgiving oneself, and perceptions of conditionality in God's forgiveness. Religious commitment was related to reporting more a more forgiving attitude on seven of these dimensions, but also to more perceived conditionality in God's forgiveness. Finally, differences in mean levels of forgiveness emerged between birth cohorts.     

Religious involvement,helping others,and psychological well-being

This study has two goals. The first goal is to see if involvement in religion is associated with providing tangible support to family members and strangers. The second goal is to see if providing tangible support to family members and strangers is associated with well-being. A conceptual model, which was developed to address these issues, contains the following core relationships: (1) individuals who go to church more often will receive more spiritual support from coreligionists; (2) those who receive more spiritual support will provide more tangible assistance to family members and strangers; and (3) people who help family members and strangers will report greater life satisfaction and higher self-esteem. Findings from a nationwide survey support all but one of these relationships. More specifically, the results suggest that providing tangible support to family members is associated with greater well-being, but providing tangible support to strangers is not associated with well-being.     

Church service roles and anticipated support among older Mexican Americans

The purpose of this study is to see how feelings of anticipated support arise in church. Anticipated support refers to the belief that coreligionists will provide assistance in the future if the need arises. This model contains the following hypothesis: (1) people who affiliate with conservative Protestant congregations will be more deeply committed to their faith, (2) individuals who are more committed to their faith will attend church more frequently, (3) people who go to church more often will be more likely to occupy church service roles, (4) those who occupy church service roles will feel more highly valued by their coreligionists, (5) individuals who feel they are valued highly by fellow church members will receive more emotional support from them, and (6) people who receive more emotional support at church will have stronger anticipated support beliefs. Data from a nationwide survey of older Mexican Americans support these hypotheses.     

The effects of a token reinforcement procedure on bus ridership

Tokens, exchangeable for a variety of back-up reinforcers, were delivered for several days to all persons boarding a clearly marked campus bus. This procedure increased ridership to 150% of baseline. The experiment was carried out to demonstrate the applicability of operant techniques to urban transportation problems. In this study, a token reinforcement procedure was introduced in an attempt to increase bus ridership while holding the costs of reinforcers to a minimum and circumventing the problems of individual satiety and preferences and of delivering cumbersome reinforcers. A methodology for establishing a token-exchange procedure in an "open-field" behavior setting, where the subject population size, geographic location, preferences, age, sex, preferred hours of mobility, etc. are unspecified, is also presented.
