A two-point visual control model of steering

When steering down a winding road, drivers have been shown to use both near and far regions of the road for guidance during steering. We propose a model of steering that explicitly embodies this idea, using both a 'near point' to maintain a central lane position and a 'far point' to account for the upcoming roadway. Unlike control models that integrate near and far information to compute curvature or more complex features, our model relies solely on one perceptually plausible feature of the near and far points, namely the visual direction to each point. The resulting parsimonious model can be run in simulation within a realistic highway environment to facilitate direct comparison between model and human behavior. Using such simulations, we demonstrate that the proposed two-point model is able to account for four interesting aspects of steering behavior: curve negotiation with occluded visual regions, corrective steering after a lateral drift, lane changing, and individual differences.     

A Critical Review of the Clinical Effects of Therapeutic Irradiation Damage to the Brain: The Roots of Controversy

We critically examined the damaging affects of therapeutic irradiation by comparing results from cross-disciplinary studies of early- and late-delayed radiotherapy effects. Focus is attained by concentrating on clinical treatment issues (volume of brain, dose, timing of effects, age, modality types, and stereotactic treatment techniques), rather than on methodological means or problems, which is necessary to understand the mechanisms and characteristics of radiotherapy-induced behavioral dysfunction including cognition. We make observations and hypotheses about the actual risks from radiotherapy that could be informative in the treatment decision process, and which may lessen the concerns of some patients and their families about the risks they take when receiving radiation. Conditions that predispose to radiation injury are reviewed: (1) higher doses even to part of the brain versus lower doses to the whole brain, (2) combined treatment modalities, (3) malignancy itself, (4) radiation early during postnatal brain development, and (5) late-delayed effects (more than 3 years posttreatment). Current neurocognitive frameworks for understanding cognitive change over time in children and adults are summarized, along with the literature on effects of brain tumors and treatment on depression. No studies have as yet identified candidate brain regions that are more sensitive to radiotherapy. Two studies have provided early, preliminary evidence for a specific vulnerability of visual attention/memory to the early stage of late radiation damage. Furthermore, radiation effects appear severe only in a minority of patients. Risk is related to direct and indirect effects of cancer type, concurrent clinical factors, and premorbid risk factors.     

Young women struggling for an identity

In this article, I propose that many young women in today's world are facing an intense internal struggle to find their identity, and that this struggle is an effect of what they experience as enormous pressure to achieve certain goals. My belief is that, in the contemporary atmosphere of postfeminism in which women seemingly have many more options, the young adult woman experiences these options as expectations. The effect of these demands is an enormous self-doubt where women feel worthless, unimportant, and often unable to go forward in their lives. This article focuses on the stories of 3 young women and their struggles: a 25-year-old White middle-class woman whose obsessive longing to find the "right" man leads to eating difficulties; a 23-year-old lesbian, also White, who is just graduating from college and believes that she is terminally depressed; and a 29-year-old Chinese American woman who has fought anxiety and chronic fatigue for most of her adult life. How they find their way clearly exemplifies both the struggle and the road to success--overcoming self-doubt and challenging the expectations that create the conditions for it.     

Therapists' group attachments and their expectations of patients' attitudes about group therapy

A large body of literature has supported the application of attachment theory to the understanding of psychotherapy. In addition, a more recent social psychological literature is exploring the application of attachment theory to the area of group dynamics and group process. The current study is designed to integrate these two distinct bodies of literature. In a preliminary fashion, we examined the relationship between group therapists' group attachment styles and their assumptions and expectations of their patients' attitudes about group psychotherapy. Seventy-six therapists completed the Smith, Murphy & Coats (1999) measure of group attachment style. They also completed the Revised Group Therapy Survey (Carter, Mitchell, & Krautheim, 2001) from the viewpoint of a typical patient they treat. As hypothesized, therapists with more group attachment anxiety assumed that patients would hold more negative myths and misconceptions about group treatment than therapists with less group attachment anxiety. The utility of a group attachment construct in future research and practice is discussed.     

Internal Realism and the Problem of Religious Diversity

This article applies Hilary Putnam’s theory of internal realism to the issue of religious plurality. The result of this application – ‘internalist pluralism’ – constitutes a paradigm shift within the Philosophy of Religion. Moreover, internalist pluralism succeeds in avoiding the major difficulties faced by John Hick’s famous theory of religious pluralism, which views God, or ‘the Real,’ as the noumenon lying behind diverse religious phenomena. In side-stepping the difficulties besetting Hick’s revolutionary Kantian approach, without succumbing to William Alston’s critique of conceptual-scheme dependence, internalist pluralism provides a solution to significant theoretical problems, while doing so in a manner that is respectful of cultural diversity and religious sensitivities.

Women abuse: beliefs and attitudes in university students

Beliefs and attitudes positives toward domestic violence are one of the risks factors for his occurrence. Among his most studied predictors are gender, gender role attitudes or educational level. In this paper, domestic violence beliefs and attitudes are analysed in 1395 university students. "Inventory of Thoughts Distorted on the Woman and the Violence" (Echeburúa and Fernández-Montalvo, 1997) and "Inventory of Social Desirability" by Crowne and Marlowe (Form C, Reynolds, 1982) were administrated. Boys and students without specific formation about this subject show more positive beliefs and attitudes toward domestic violence. Though social desirability introduces some limitations, these results suggest the importance of incorporating matters on this subject in the curriculum of university students in general and, especially, in future professional that will work with these groups.     

The differential depiction of female athletes in judged and non-judged sport magazines

Sports magazines portrayal of female athletes over the past ten years, in terms of body size, age, and race was examined. Using the Contour Drawing Rating Scale (CDRS), estimated body size was obtained for cover models on a set of judged and non-judged sport magazines. The frequency with which the full bodies of models were depicted on the covers of these magazines was also investigated. Cover models on judged sport magazines were rated as significantly thinner than cover models on non-judged sport magazines. Judged sport magazines also displayed a higher number of full-body images than non-judged sport magazines. These findings suggest that individuals who read judged sport magazines are more likely to be exposed to thin media images than those reading non-judged sport magazines.     

Romantic involvement often reduces men's testosterone levels--but not always: the moderating role of extrapair sexual interest

Testosterone (T) appears to facilitate what biologists refer to as mating effort--the investment of time and energy into same-sex competition and mate-seeking behavior. Multiple studies show that men who are romantically involved (i.e., are paired) have lower T than single men, which may be due to a facultative adjustment by men of T levels in response to lower demands for mating effort. The authors proceeded on the basis of the idea that men who retain interests in sexual opportunities with women other than a primary partner continue to dedicate more time and energy to mating effort when romantically paired, and so they predicted that the association between relationship status and T depends on men's extrapair sexual interests. Study 1 used the Sociosexual Orientation Inventory to measure extrapair sexual interests, whereas Study 2 used a broader measure to examine this interaction. Both studies found support for it. These results have implications for an understanding of the biosocial regulation of men's behavior in romantic relationships.     

Client Perceptions of and Preferences for University-Based Career Services

One hundred thirty-three students who were actively seeking career services reported on their perceptions of the similarity among, and their preferences for, 17 different types of career assistance by way of a paired comparison task. Multidimensional scaling (MDS) and multidimensional preference modeling procedures were used to map these data into spatial representations. Ethnicity, international/domestic student status, tendency to foreclose (TTFS; Blustein, Ellis, & Devenis, 1989), and previous experience with an interest inventory each accounted for differences in perceptions. All participants preferred career assistance involving direct interaction with employed individuals, but class level, occupational status, previous participation in a career development class, and previous experience with career counseling accounted for differences in preferences.     

Perception of speech and nonspeech stimuli by children with and without reading disability and attention deficit hyperactivity disorder

The auditory temporal deficit hypothesis predicts that children with reading disability (RD) will exhibit deficits in the perception of speech and nonspeech acoustic stimuli in discrimination and temporal ordering tasks when the interstimulus interval (ISI) is short. Initial studies testing this hypothesis did not account for the potential presence of attention deficit hyperactivity disorder (ADHD). Temporal order judgment and discrimination tasks were administered to children with (1) RD/no-ADHD (n=38), (2) ADHD (n=29), (3) RD and ADHD (RD/ADHD; n=32), and (4) no impairment (NI; n=43). Contrary to predictions, children with RD showed no specific sensitivity to ISI and performed worse relative to children without RD on speech but not nonspeech tasks. Relationships between perceptual tasks and phonological processing measures were stronger and more consistent for speech than nonspeech stimuli. These results were independent of the presence of ADHD and suggest that children with RD have a deficit in phoneme perception that correlates with reading and phonological processing ability.
