Dissociating viewpoint costs in mental rotation and object recognition

In a mental rotation task, participants must determine whether two stimuli match when one undergoes a rotation in 3-D space relative to the other. The key evidence for mental rotation is the finding of a linear increase in response times as objects are rotated farther apart. This signature increase in response times is also found in recognition of rotated objects, which has led many theorists to postulate mental rotation as a key transformational procedure in object recognition. We compared mental rotation and object recognition in tasks that used the same stimuli and presentation conditions and found that, whereas mental rotation costs increased relatively linearly with rotation, object recognition costs increased only over small rotations. Taken in conjunction with a recent brain imaging study, this dissociation in behavioral performance suggests that object recognition is based on matching of image features rather than on 3-D mental transformations.     

The interference effect of men's handling of muscular action figures on a lexical decision task

It has been shown in previous work [Action figures and men. Sex Roles 53, 877–885] that male participants who handled extremely muscular action figures had lower body esteem than those who did not handle action figures or a Ken doll. However, the internal mechanisms that dictated this effect are unclear. Therefore, the current study extended this previous work by having male participants handle action figures of varying muscularity and completing a lexical decision task with target words that consisted of both positive and negative body words and feeling words in order to determine if males would be primed to think negatively about their bodies and self or if positive thoughts about their bodies and self would be interfered with. The results show that those participants who handled the extremely muscular action figures responded significantly more slowly to feeling positive words (e.g., content, confident) and marginally more slowly to body positive words (e.g., muscle, bicep) than those who did not handle any action figures. Overall, this suggests that the interference of positive words, not the priming of negative words, is the internal mechanism that produces the decreased body image satisfaction after exposure to muscular stimuli. Implications and future research are discussed.     

A test of the tau-dot hypothesis of braking control in the real world

A controlled experiment used instrumented vehicles in a real-world driving task to compare D. N. Lee's (1976) tau-dot hypothesis of braking control with an alternative based on the direct estimation and control of ideal deceleration (T. Yates, M. Harris, & P. Rock, 2004). Drivers braked to stop as closely as possible to a visual target from different starting speeds and times-to-contact. The data provided little support for the tau-dot hypothesis, and analysis suggested that braking in the real world is better explained by a direct deceleration strategy.     

Teenagers' attitudes about seeking help from telephone crisis services (hotlines)

The purpose of this study was to examine the attitudes toward the use of telephone crisis services (hotlines) among 519 adolescents in 9th through 12th grade mandatory health courses in six high schools in New York State. Few adolescents (2.1%) used hotlines and negative attitudes were stronger toward hotlines than they were toward other formal sources of help. The most common reasons for hotline nonuse related to feelings of self-reliance and shame. Objections to hotlines were strongest among students most in need of help by virtue of impaired functioning or feelings of hopelessness. The results underscore needed outreach efforts to youth.     

Elemental representations of stimuli in associative learning

This article reviews evidence and theories concerning the nature of stimulus representations in Pavlovian conditioning. It focuses on the elemental approach developed in stimulus sampling theory (R. C. Atkinson & W. K. Estes, 1963; R. R. Bush & F. Mosteller, 1951b) and extended by I. P. L. McLaren and N. J. Mackintosh (2000, 2002) and contrasts this with models that invoke notions of configural representations that uniquely code for different patterns of stimulus inputs (e.g., J. M. Pearce, 1987, 1994; R. A. Rescorla & A. R. Wagner, 1972; A. R. Wagner & S. E. Brandon, 2001). The article then presents a new elemental model that emphasizes interactions between stimulus elements. This model is shown to explain a range of behavioral findings, including those (e.g., negative patterning and biconditional discriminations) traditionally thought to be beyond the explanatory capabilities of elemental models. Moreover, the model offers a ready explanation for recent findings reported by R. A. Rescorla (2000, 2001, 2002b) concerning the way that stimuli with different conditioning histories acquire associative strength when conditioned in compound.     

Am I doing better than you? That depends on whether you ask me in English or Chinese: Self-enhancement effects of language as a cultural mindset prime

Westerners tend to judge themselves positively unless their failure relative to others is obvious, in which case they tend to distance themselves from outperforming others. Whether this tendency to self-enhance in social-comparison situations is universal or culture-bound is hotly debated. Rather than construe self-enhancement as either universal or culture-bound, we propose that its effects depend on the cultural mindset that is salient at the moment of self-reflection. A cultural mindset is a mental representation containing culture-congruent content, procedures, and goals. We focused on individual and collective mindsets, using language as an unobtrusive mindset prime and predicting that people would be more self-enhancing when an individual mindset was made salient by using English than when a collective mindset was made salient by using Chinese. Three studies supported this hypothesis. Chinese students self-enhanced (rating themselves as better than others and distancing themselves from outperforming others) more when primed with an individual mindset.     

More than just skin deep? Personality information influences men's ratings of the attractiveness of women's body sizes

This study examined the influence of personality information on perceptions of the physical attractiveness of a range of female body sizes. A sample of 2,157 male university students were randomly assigned to one of 10 groups in which they received personality information about women they were rating, or a control group in which they received no personality information. Controlling for participants' age and body mass index, results showed no significant between-group differences in the body size that participants found most attractive. However, participants provided with positive personality information perceived a wider range of body sizes as physically attractive compared with the control group, whereas participants provided with negative personality information perceived a narrower range of body sizes as attractive. Correlations showed that participants' own Extraversion was associated with their body size ratings. These results suggest that non-physical cues have an influence on the perception of physical beauty.     

Relationship between a history of consistent maternal employment and depression in young adults

Research on the correlates of maternal employment has yielded inconsistent results. In this study, 79 male and 120 female undergraduates with mothers who had been employed from the students' infancy through their adolescence scored higher on the Beck Depression Inventory-II than those whose mothers had not been employed. This relationship between children's depressive symptoms and mothers' employment history was not evident among young adults whose mothers' employment was perceived to be financially unnecessary.     

Constraining the Ruler: On Escaping Han Fei's Criticism of Confucian Virtue Politics

One of Han Fei's most trenchant criticisms against the early Confucian political tradition is that, insofar as its decision-making process revolves around the ruler, rather than a codified set of laws, this process is the arbitrary rule of a single individual. Han Fei argues that there will be disastrous results due to ad hoc decision-making, relationship-based decision-making, and decision-making based on prior moral commitments. I lay out Han Fei's arguments while demonstrating how Xunzi can successfully counter them. In doing so, I argue that Xunzi lays out a political theory restricting the actions of the ruler through both the use of ritual and law, which allows him to develop a theory that legitimizes government while at the same time constraining itself. Xunzi's political theory makes important strides in its attempt to recognize the importance of the ruler as a moral exemplar while also restricting his control in the political process.
