Heightened sensitivity to facial expressions of emotion in borderline personality disorder

Individuals with borderline personality disorder (BPD) have been hypothesized to exhibit significant problems associated with emotional sensitivity. The current study examined emotional sensitivity (i.e., low threshold for recognition of emotional stimuli) in BPD by comparing 20 individuals with BPD and 20 normal controls on their accuracy in identifying emotional expressions. Results demonstrated that, as facial expressions morphed from neutral to maximum intensity, participants with BPD correctly identified facial affect at an earlier stage than did healthy controls. Participants with BPD were more sensitive than healthy controls in identifying emotional expressions in general, regardless of valence. These findings could not be explained by participants with BPD responding faster with more errors. Overall, results appear to support the contention that heightened emotional sensitivity may be a core feature of BPD.     

Resource slack and propensity to discount delayed investments of time versus money

The authors demonstrate that people discount delayed outcomes as a result of perceived changes over time in supplies of slack. Slack is the perceived surplus of a given resource available to complete a focal task. The present research shows that, in general, people expect slack for time to be greater in the future than in the present. Typically, this expectation of growth of slack in the future is more pronounced for time than for money. In 7 experiments, the authors demonstrate that systematic temporal shifts of perceived slack determine the extent and the pattern of delay discounting, including hyperbolic discounting. They use this framework to explain differential propensity to delay investments and receipts of time and money.     

Therapeutic techniques vs therapeutic relationships in child behavior therapy

The parents of 56 children who had received behavior therapy rated a number of variables, including the degree to which they viewed the therapeutic relationship versus the specific techniques used in treatment as important, the extent to which the child improved in therapy, and the child's present functioning. Therapists also provided ratings of clinical improvement. Even though parents gave the highest ratings for the importance of the relationship in therapy, the correlation between technique and clinical outcome was statistically significant while the correlations between the relationship and outcome was not. These statistical associations also held when therapists rated improvement. Also, therapists saw greater improvement in children than did the parents. Over-all, the results support the view that the relationship and techniques are interwoven and are both perceived as important factors in treatment.     

A ToolBook computer program to develop course objectives and assessment measures

College courses are generally developed because of current fashion in the field and/or student and faculty interest in some topic without reference to departmental or programmatic goals. Current calls and needs for accountability in higher education demand a more organized approach. A computer program, ToolBook 1.53, which provides information to the instructor about systematic development of courses and assessment of student outcomes, is described. The program supports the construction of outcome-oriented learning objectives and corresponding assessment techniques. Instructors who used this program to learn about how to construct such objectives showed an increase in knowledge and evaluated the program positively. Using the information provided in this program leads to an integrated approach to course design and development in which course objectives are linked to the college mission statement through departmental or program objectives.     

Sex differences in fetal habituation

There is some evidence for sex differences in habituation in the human fetus, but it is unknown whether this is due to differences in central processing (habituation) or in more peripheral processes, sensory or motor, involved in the response. This study examined whether the sex of the fetus influenced auditory habituation at 33 weeks of gestation, and whether this was due to differences in habituation or in the sensory or motor components using a set of four experiments. The first experiment found that female fetuses required significantly fewer stimulus presentations to habituate than males. The second experiment revealed no difference in the spontaneous motor behaviour of male and female fetuses. The third experiment examined auditory intensity thresholds for the stimuli used to habituate the fetus. No differences in thresholds were found between males and females, although there was inter-individual variability in thresholds. A final experiment, using stimuli individualized for that particular fetus' auditory intensity threshold, found that female fetuses habituated faster than males. In combination, the studies reveal that habituation in the human fetus is affected by sex and this is due to a difference in central 'information processing' of the stimuli rather than peripheral aspects of the response. It is argued that male and female fetuses present different neurobehavioural developmental trajectories, with females more advanced at 33 weeks than males. This study suggests that research examining prenatal behaviour should consider the factor of fetal sex. This may be particularly pertinent where there is an intention to use the results diagnostically.     

Catholic/Jesuit Values in an Introductory Religious Studies Course

A growing interest in the communication to students of the mission and identity of a higher education institution prompted this study about the presence of Catholic, Jesuit values in the introductory religious studies course at a faith‐based university. To conduct this study a survey instrument was developed, piloted, further refined, and then administered again to about four hundred and fifty students. The study's results showed that the introductory course had a positive effect on the majority of students surveyed, namely, those who had no Catholic schooling or only had a Catholic elementary school education. Statistically significant advances in several areas of knowledge about Catholic teachings endorsed by Catholic bishops and the pope occurred. Although less extensive, knowledge of Jesuit values also advanced in the course.     

A Multiple Realization Thesis for Natural Kinds

Abstract: Two important thought‐experiments are associated with the work of Hilary Putnam, one designed to establish multiple realizability for mental kinds, the other designed to establish essentialism for natural kinds. Comparing the thought‐experiments with each other reveals that the scenarios in both are structurally analogous to each other, though his intuitions in both are greatly at variance, intuitions that have been simultaneously well received. The intuition in the former implies a thesis that prioritizes pre‐scientific over scientific indicators for identifying mental kinds in certain circumstances, while his intuition in the latter implies a converse thesis, prioritizing scientific over pre‐scientific indicators for identifying natural kinds in analogous circumstances. In this paper I question whether we can consistently endorse both of these intuitions. A consideration is presented to attempt to justify the common intuition found in the multiple realization thought‐experiment. Then it is argued that this same consideration has application in the structurally analogous Twin‐Earth thought‐experiment. This recommends a kind of multiple realization thesis for natural kinds, in opposition to a scientific essentialist approach. The various respects in which mental kinds like pain and natural kinds like water are similar to each other, such that similar philosophical treatments are warranted for both, are enumerated.     

Rates and Types of Student Aggression against Teachers: A Comparative Analysis of U.S. Elementary,Middle, and High Schools

Student perpetrated violence against teachers is widespread, yet few studies differentiate teacher experiences of violence by school level (i.e., elementary, middle, and high school). This study, based upon 2,558 pre-kindergarten through 12^th grade teacher survey responses, revealed differences in types of student aggression against teachers by school level. Middle and high school teachers were more likely to report verbal harassment compared to elementary school teachers. Middle school teachers were most likely to report property offenses. Elementary and middle school teachers were more likely to report physical aggression than high school teachers. Demographic predictors of teacher-directed violence were also examined at each school level. Across all school levels, urban teachers had a greater probability of experiencing a violent incident. For elementary teachers, race/ethnicity and teaching experience were also significant risk factors. Future research, policy, and practice implications and recommendations are discussed.
