Intuitions,theory choice and the ameliorative character of logical theories

Synthese - Anti-exceptionalists about logic claim that logical methodology is not different from scientific methodology when it comes to theory choice. Two anti-exceptionalist accounts of theory...     

Unintended Consequences of EEO Enforcement Policies: Being Big is Worse than Being Bad

In enforcing the Civil Rights Acts of 1964 and 1991, it is often critical to determine whether a challenged procedure has systematic adverse impact. The use of statistical significance tests to make this determination has the perverse consequence that the size of an organization or an applicant pool has more impact on determining adverse impact than the extent to which procedures actually discriminate. That is, it is worse to be big than to be bad. We use Monte Carlo studies to illustrate this unforeseen consequence of current enforcement policies and note that a broader definition of adverse impact is clearly warranted.     

Ipsilesional Arm Motor Sequence Performance After Right and Left Hemisphere Damage

Aiming movements are part of daily activities but the brain hemispheres’ role in targeted aiming sequential movements is not fully clear. Start and execution of discrete and sequential tasks toward targets were analyzed in 10 individuals with left-hemisphere damage, 10 right-hemisphere–damaged, and 10 healthy ones. Arm movements were performed over a digitizing tablet, following stimuli on a monitor, from initial position toward right and left-positioned targets. Poststroke individuals used their ipsilesional arm and healthy individuals, both arms. Right-hemisphere–damaged individuals showed higher reaction time and left-hemisphere–damaged individuals, lower smoothness. Due to spatial demand of tasks, the right hemisphere played a major role in movement planning, while the left, in movement execution.     

Cognitive-Based Compassion Training: A Promising Prevention Strategy for At-Risk Adolescents

Compared to the general population, youth in foster care experience multiple psychosocial difficulties due to exceptionally high rates of maltreatment. Many youth in care receive psychological and/or psychotropic treatment but not all require or are willing to accept that level of intervention. For many, a “mental health” approach feels pathologizing. Nevertheless, these youth have suffered maltreatment and interventions to improve their ability to cope with past trauma and their often uncertain present are clearly needed. Cognitively-Based Compassion Training (CBCT) provides an alternative perspective on suffering and can be framed as a wellness intervention that is appropriate for all humans. The present study examined whether a 6-week CBCT intervention would improve psychosocial functioning among adolescents in foster care. Seventy adolescents were randomized to CBCT (twice weekly) or a wait-list condition. Youth were assessed at baseline and after 6 weeks. Groups did not differ on measures of psychosocial functioning following training; however practice frequency was associated with increased hopefulness and a trend for a decrease in generalized anxiety. Qualitative results indicated that participants found CBCT useful for dealing with daily life stressors. Adolescents in care were willing to engage in CBCT. The majority reported CBCT was very helpful and almost all reported they would recommend CBCT to a friend. Participants reported specific instances of using CBCT strategies to regulate emotion, manage stress, or to respond more compassionately towards others. Standardized self-report measures were not sensitive to qualitative reports of improved functioning, suggesting the need for measures more sensitive to the positive changes noted or longer training periods to demonstrate effects. Practical issues surrounding implementation of such programs in high-risk youth populations are identified. Recommendations are provided for further development.     

Does Gender Affect Visiting a World Heritage Site?

ABSTRACT

The city of Guimarães in Portugal is a place of strong symbolic and cultural significance, and the nomination of its historical center as a World Heritage Site in 2001 enhanced its tourism potential. This study presents the results of a survey conducted in 2010 and 2011 to capture the profile and motivations of tourists visiting Guimarães as a cultural tourism destination. The study addressed two main issues: whether males and females have similar or different preferences in choosing the city as their destination, and whether there are gender differences in the perception of the attributes of Guimarães. A better understanding of the gendered nature of the destination is a valuable cue for shaping products and services according to visitors’ preferences. The results suggest that both men and women are aware of the main elements responsible for the city's World Heritage status. That the destination is a Heritage Site that also offers the opportunity to tour the region has a significant positive effect on male tourists’ choice of Guimarães. Regarding the perceived attributes of the city, results indicate minor gender differences with one exception: Women expressed more apprehension than men regarding the perceived security of the destination.     

Exploring the perception of social characteristics in faces using the isolation effect

The age, sex, and distinctiveness of faces can be judged from objective and partially independent facial features. In contrast, the physical basis of other social judgements, such as attractiveness, intelligence, and trustworthiness is not as yet entirely understood, despite the consistency of these judgements from faces. The present set of experiments investigated the perception of social characteristics in faces, using an adaptation of the von Restorff/isolation paradigm to determine which social characteristics are spontaneously encoded from the face. The isolation effect involves enhanced memory for perceptually salient items in a list (items that are isolated in the sense that they are in numeric minority) and our results suggested that its locus is at the encoding stage of the recognition memory experiment. Isolation in the present experiments was achieved by manipulating the number of faces included in the sets on the basis of certain characteristics. Because the manipulation of the characteristics of faces in a set to be learnt was not mentioned in most of the experiments, any resulting memory increment for the isolated items could be taken as an index of spontaneous processing of the manipulated social characteristic. Age and sex were found to be spontaneously encoded from faces. Results for other characteristics were mixed, ranging from distinctiveness and attractiveness, for which there was some indication of spontaneous processing, to intelligence and trustworthiness, which did not seem to be spontaneously encoded from faces. For intelligence, an isolation effect was found only when the experiment required a judgement that led to activation of the appropriate stereotype.     

Good-Enough Representations in Language Comprehension

People comprehend utterances rapidly and without conscious effort. Traditional theories assume that sentence processing is algorithmic and that meaning is derived compositionally. The language processor is believed to generate representations of the linguistic input that are complete, detailed, and accurate. However, recent findings challenge these assumptions. Investigations of the misinterpretation of both garden-path and passive sentences have yielded support for the idea that the meaning people obtain for a sentence is often not a reflection of its true content. Moreover, incorrect interpretations may persist even after syntactic reanalysis has taken place. Our good-enough approach to language comprehension holds that language processing is sometimes only partial and that semantic representations are often incomplete. Future work will elucidate the conditions under which sentence processing is simply good enough.
