A goal-based perspective on eye movements in visual world studies

There is an emerging literature on visual search in natural tasks suggesting that task-relevant goals account for a remarkably high proportion of saccades, including anticipatory eye movements. Moreover, factors such as “visual saliency” that otherwise affect fixations become less important when they are bound to objects that are not relevant to the task at hand. We briefly review this literature and discuss the implications for task-based variants of the visual world paradigm. We argue that the results and their likely interpretation may profoundly affect the “linking hypothesis” between language processing and the location and timing of fixations in task-based visual world studies. We outline a goal-based linking hypothesis and discuss some of the implications for how we conduct visual world studies, including how we interpret and analyze the data. Finally, we outline some avenues of research, including examples of some classes of experiments that might prove fruitful for evaluating the effects of goals in visual world experiments and the viability of a goal-based linking hypothesis.     

Post‐identification feedback effects: Investigators and evaluators

We investigated the effects of post‐identification feedback and viewing conditions on beliefs and interviewing tactics of participant‐investigators, crime reports of participant‐witnesses and participant‐evaluators' credibility judgments of the witnesses. Study 1 participants assumed the roles of witness and investigator (N = 167 pairs). Witnesses' view of a simulated crime video was manipulated by distance from viewing monitor: 2 or 9 ft. Participants made a line‐up identification and received either positive feedback or no feedback. Significant effects for witnesses and investigators were associated with viewing condition and post‐identification feedback. Interviews between investigator‐witness pairs were videotaped. Investigators asked more positive, leading questions when they were led to believe that the witness had identified the suspect. In Study 2 evaluators (N = 302) viewed the witness‐investigator interviews. Viewing condition had no effect on judgments of witness credibility but positive post‐identification feedback led evaluators to judge witnesses as more credible than witnesses who received no feedback.

Enriching the Genetic Counseling Recruitment Pipeline: A National Cross-Sectional Study of Public High School Counselors

Early awareness of careers is helpful in recruiting students into a career pipeline. School counselors are among the top resources that students turn to when seeking advice about choosing their career. Studies show that high school is the ideal time to generate interest in the genetic counseling career, especially for minorities. This novel study of 291 high school counselors working in ethnically diverse public school districts in the United States examined to what extent members of this important group discuss genetic counseling as a career option with their students. The findings indicate that the majority of school counselors in this study (83%) did not discuss genetic counseling with their students, citing a lack of resources and lack of student interest as the major barriers. Suggestions of ways to increase high school counselors’ awareness of the genetic counseling career in order to enhance the goal of enriching recruitment of ethnic minorities into the genetic counseling pipeline are presented.     

Can Perceived Burdensomeness Explain the Relationship Between Suicide and Perfectionism?

The perception of being a burden to others has been associated with suicidal ideation and behavior. Maladaptive aspects of perfectionism have also been associated with suicidal thinking and behavior. The purpose of the current study was to investigate whether perceived burdensomeness would act as a mediator between maladaptive perfectionism and suicidal ideation. Results indicated that perceived burdensomeness mediated the relationship between maladaptive perfectionism and suicidal ideation, which suggest that the perception of burdensomeness may be one aspect of the mechanism by which perfectionism can lead to such psychological distress that it becomes a predictor of suicidal ideation. Clinical implications of this relationship are discussed.     

Delineating the sequelae of destructive and constructive interparental conflict for children within an evolutionary framework

We examined the joint role of constructive and destructive interparental conflict in predicting children's emotional insecurity and psychological problems. In Study 1, 250 early adolescents (M = 12.6 years) and their primary caregivers completed assessments of family and child functioning. In Study 2, 201 mothers and their 2-year-old children participated in a multimethod, longitudinal design with 3 annual measurement occasions. Findings from structural equation modeling in both studies revealed that children's emotional insecurity in the interparental relationship mediated associations between destructive interparental conflict and children's psychological problems even after including constructive conflict and family and child covariates as predictors. Conversely, emotional insecurity was not a mediator of associations between constructive interparental conflict and children's psychological problems when destructive interparental conflict was specified as a risk factor in the analyses. The results are consistent with the evolutionary reformulation of emotional security theory and the resulting primacy ascribed to destructive interparental conflict in accounting for individual differences in children's emotional insecurity and its pathogenic implications (Davies & Sturge-Apple, 2007).     

Religion and Decisions About Marriage,Residence, Occupation,and Children

Using data from the first wave of the Portraits of American Life Study (PALS), we consider the extent to which people report that religious factors influence their decisions about career choice, marriage, residency, and number of children. We find significant positive relationships between the importance of religion or religious faith and the perceived influence of religious factors on one's choice of occupation, decision about whether or whom to marry, decision about where to live, and decision about how many children to have. We also observe significant interactions between the importance of religion or religious faith and religious tradition, but we find no consistent patterns across our decision‐making outcomes. Our preliminary conclusions raise significant questions about the broader relationship between religion, perception, and decision making.     

The Effects of Magnitude-Based Differential Reinforcement on the Skill Acquisition of Children with Autism

A common recommendation for teaching skills to children with autism is to apply differential reinforcement by reserving high-quality reinforcement for unprompted responses (Sundberg and Partington in Teaching language to children with autism or other developmental disabilities, Behavior Analysts Inc., Pleasant Hill, 1998). Earlier research focuses primarily on schedules or quality of reinforcement, rather than magnitude of reinforcement, when evaluating the use of differential reinforcement in practice. The utility of magnitude-based differential reinforcement may be dependent upon evidence that a learner responds differentially to large and small amounts of reinforcement such that he or she selects the large amount of reinforcement over the small amount of reinforcement and engages in more responses that produce the relatively larger magnitude reinforcement. Three individuals with autism participated in a treatment comparison of differential reinforcement. The manipulation of magnitude of differential reinforcement in a skill acquisition program did not have an appreciable effect on the rate of acquisition for any of the three participants.     

Attitudes and Practices Among Internists Concerning Genetic Testing

Many questions remain concerning whether, when, and how physicians order genetic tests, and what factors are involved in their decisions. We surveyed 220 internists from two academic medical centers about their utilization of genetic testing. Rates of genetic utilizations varied widely by disease. Respondents were most likely to have ordered tests for Factor V Leiden (16.8 %), followed by Breast/Ovarian Cancer (15.0 %). In the past 6 months, 65 % had counseled patients on genetic issues, 44 % had ordered genetic tests, 38.5 % had referred patients to a genetic counselor or geneticist, and 27.5 % had received ads from commercial labs for genetic testing. Only 4.5 % had tried to hide or disguise genetic information, and <2 % have had patients report genetic discrimination. Only 53.4 % knew of a geneticist/genetic counselor to whom to refer patients. Most rated their knowledge as very/somewhat poor concerning genetics (73.7 %) and guidelines for genetic testing (87.1 %). Most felt needs for more training on when to order tests (79 %), and how to counsel patients (82 %), interpret results (77.3 %), and maintain privacy (80.6 %). Physicians were more likely to have ordered a genetic test if patients inquired about genetic testing (p?<?.001), and if physicians had a geneticist/genetic counselor to whom to refer patients (p?<?.002), had referred patients to a geneticist/genetic counselor in the past 6 months, had more comfort counseling patients about testing (p?<?.019), counseled patients about genetics, larger practices (p?<?.032), fewer African-American patients (p?<?.027), and patients who had reported genetic discrimination (p?<?.044). In a multiple logistic regression, ordering a genetic test was associated with patients inquiring about testing, having referred patients to a geneticist/genetic counselor and knowing how to order tests. These data suggest that physicians recognize their knowledge deficits, and are interested in training. These findings have important implications for future medical practice, research, and education.     

Prospective Prediction of College Adjustment Using Self- and Informant-Rated Personality Traits

Summary: While the Activity Preference Questionnaire (APQ) appears to provide unusually pure and subtle measures of anxiety proneness, its forced choice format involves several drawbacks. Data are presented which suggest that a rating format can be used which avoids the disadvantages of the forced choice format but incorporates its advantages.
