An investigation of adult attachment and coping with exam-related stress

Students differ in how they cope with and manage stress associated with university life. This study investigates associations between adult attachment and coping strategies for exam-related stress. Fifty-seven students at a university in the north of England completed online questionnaires to assess attachment anxiety and avoidance, helpful and unhelpful coping strategies, and positive and negative affect. We found that students who were more avoidant in their attachment relationships were less likely to report using helpful problem-focused and emotion-focused strategies to cope with their exams. We also found that students who were more anxious in their attachment relationships reported using more dysfunctional coping strategies. We discuss the implications of the findings for university pastoral care and academic support systems.     

On the development and mechanics of delayed matching-to-sample performance

Despite its frequent use to assess effects of environmental and pharmacological variables on short-term memory, little is known about the development of delayed matching-to-sample (DMTS) performance. This study was designed to examine the dimensions and dynamics of DMTS performance development over a long period of exposure to provide a more secure foundation for assessing stability in future research. Six pigeons were exposed to a DMTS task with variable delays for 300 sessions (i.e., 18,000 total trials; 3,600 trials per retention interval). Percent-correct and log-d measures used to quantify the development of conditional stimulus control under the procedure generally and at each of five retention intervals (0, 2, 4, 8 and 16-s) individually revealed that high levels of accuracy developed relatively quickly under the shorter retention intervals, but increases in accuracy under the longer retention intervals sometimes were not observed until 100-150 sessions had passed, with some still increasing at Session 300. Analyses of errors suggested that retention intervals induced biases by shifting control from the sample stimulus to control by position, something that was predicted by observed response biases during initial training. These results suggest that although it may require a great deal of exposure to DMTS prior to obtaining asymptotic steady state, quantification of model parameters may help predict trends when extended exposure is not feasible.     

“[No] Doctor but My Master”: Health Reform and Antislavery Rhetoric in Harriet Jacobs’s Incidents in the Life of a Slave Girl

This essay examines Harriet Jacobs’s Incidents in the Life of a Slave Girl (1861) in light of new archival findings on the medical practices of Dr. James Norcom (Dr. Flint in the narrative). While critics have sharply defined the feminist politics of Jacobs’s sexual victimization and resistance, they have overlooked her medical experience in slavery and her participation in reform after escape. I argue that Jacobs uses the rhetoric of a woman-led health reform movement underway during the 1850s to persuade her readers to end slavery. This essay reconstructs both contexts, revealing that Jacobs links enslaved women’s physical and sexual vulnerability with her female readers’ fears of male doctors’ threats to modesty and of their standard bleed-and-purge treatments. Jacobs illustrates that slavery damages women’s health as much as heroic medicine, and thus merits the political activism of her readers. Specifically, Jacobs dramatizes her conflicts with the rapacious physician-master at moments that are crucial to women’s health: marriage, pregnancy, childbirth, and motherhood. Ultimately, this essay advances a new understanding of the role of health reform in social change: it galvanized other movements such as women’s rights and abolition, particularly around issues of bodily autonomy for women and African Americans.     

The Appearance‐Change Instruction Does Not Improve Line‐up Identification Accuracy

In many jurisdictions, police instruct a witness, before presenting a photo line‐up, that the suspect's appearance may be different in the photo than it was at the time of the crime. The experiments reported here examine the impact of this ‘appearance‐change instruction’ (ACI), exploring its effects with different crimes, perpetrators, line‐ups, and different phrasings of the ACI. The data indicate that the ACI increases witnesses' willingness to make a choice from a line‐up but does not increase accuracy. Copyright © 2013 John Wiley & Sons, Ltd.     

Teachers Matter: An Examination of Student-Teacher Relationships,Attitudes Toward Bullying,and Bullying Behavior

This study investigated the influence of student-teacher relationships and attitudes toward bullying on middle school students' bullying behaviors. Gender and grade differences were also examined. Data were collected from 435 middle school students. Results indicated that students' attitudes toward bullying mediated the relationship between student-teacher relationships and physical and verbal/relational bullying. There was a significant group difference on student-teacher relationships and attitudes toward bullying between bully, bully-victim, victim, and bystander groups and students not involved in bullying. In addition, sixth graders reported significantly more positive student-teacher relationships than seventh and eighth graders. Implications for the role of both cognitive and behavioral bullying intervention and prevention efforts are discussed.     

Resampling probability values for differences between two independent indices of ordinal variation and consensus

A permutation method is presented to calculate resampling probability values for differences between two independent indices of ordinal variation and consensus.     

Exact and resampling probability values for measures associated with ordered r by c contingency tables

Permutation procedures to compute exact and resampling probability values associated with measures of association for ordered r x c contingency tables are described. Comparisons with asymptotic probability values demonstrated that exact and resampling permutation procedures were preferred for sparse contingency tables.     

A measure of effect size for r x c contingency tables

Goodman and Kruskal's tau measure of categorical association is advanced as a replacement for conventional measures of effect size for r x c contingency tables. Goodman and Kruskal's tau is an asymmetric measure of categorical association which is based entirely on the observed data and possesses a clear interpretation in terms of proportional reduction in error. Comparisons with conventional measures of effect size based on chi-squared such as Pearson's phi2, Tschuprow's T2, and Cramer's V2 demonstrate the advantages of employing tau as a measure of effect size.
