Perfectionism,life events,and depressive symptoms: A test of a diathesis-stress model

The present research tested the hypothesis that perfectionists who experience stress are vulnerable to depression, in part because negative life events represent a failure to maintain control over negative outcomes. In Study 1, 215 subjects completed the Multidimensional Perfectionism Scale (MPS) and control measures. The MPS assesses self-oriented, other-oriented, and socially prescribed perfectionism. It was confirmed that self-oriented and other-oriented perfectionism were associated with both higher desire for control and greater perceived personal control. Study 2 examined whether trait levels of perfectionism moderate the link between life stress and symptoms of depression. In addition, prospective analyses investigated whether perfectionism accounts for changes in levels of depressive symptomatology over time. Two samples comprised of 374 students (Sample 1) and 173 students (Sample 2) completed the MPS and measures of major life stress and depression symptoms. Subjects in Sample 2 completed these measures at two timepoints separated by a three-month interval. Regression analyses indicated that self-oriented perfectionism and life stress interact significantly to produce higher levels of depressive symptomatology. Moreover, in Sample 2, self-oriented perfectionism at Time 1 was associated with increases in depression symptoms three months later for those individuals who had experienced a major life event. The results provide support for diathesis-stress models, which maintain that perfectionists exposed to life stress are vulnerable to symptoms of depression. The results are discussed in terms of their implications for the study of personality, stress, and vulnerability to symptoms of depression.

Processing of text containing artificial inclusion relations

The present studies were based on the hypothesis that the majority of college students have available to them the appropriate schema for understanding set inclusion relations, but that various factors influence the likelihood that the schema is used in the processing of text containing artificial inclusion relations. Although group data did not support this hypothesis, the data of individual subjects could be readily interpreted as resulting from the selection of one of a small set of representational schemata. Among the factors shown to influence schema selection were the choice of sentence frame used to present each relation, the presence or absence of real-world contextual information, and the structure (simple vs. complex) of the underlying inclusion relation. In addition, one experiment showed that the processes used in constructing a mental representation of an inclusion relation and in retrieving information from the representation are similar to those used with linear orderings.     

Habit reversal in the turtle

Two groups of mature “painted” turtles were trained in a T-maze. One group had five trials per day, with correct and incorrect turns reversed for each animal whenever it reached the criterion of five errorless trials on a given day. The second group had 10 trials per day, with correct and incorrect turns reversed daily, irrespective of the performance of the animals. Only in the data for the second group did there appear some indication of progressive improvement in habit reversal. The results are considered in relation to those obtained in analogous experiments with other species.

Arrest and intimate partner violence: Toward a more complete application of deterrence theory

Two decades of research have failed to produce consistent and compelling results that arrest deters intimate partner violence. This tradition of research is reviewed, concluding that little can be learned about the deterrent efficacy of arrest (or other sanctions) for this type of violence until a more complete framework of deterrence theory is specified to guide further research. The framework should delineate mediating influences besides deterrence, linking arrest to the prevention, reduction, or cessation of intimate partner violence, and factors that moderate those influences. Such factors bear on the differential sensitivity to sanctions on the part of actual or potential perpetrators of intimate partner violence. Recommendations for future research are offered, including suggestions for data needed to draw defensible causal inferences about these mediating and moderating influences.     

Age-related differences in the involvement of the prefrontal cortex in attentional control

We investigated the relative involvement of cortical regions supporting attentional control in older and younger adults during performance on a modified version of the Stroop task. Participants were exposed to two different types of incongruent trials. One of these, an incongruent-ineligible condition, produces conflict at the non-response level, while the second, an incongruent-eligible condition, produces conflict at both non-response and response levels of information processing. Greater attentional control is needed to perform the incongruent-eligible condition compared to other conditions. We examined the cortical recruitment associated with this task in an event-related functional magnetic resonance imaging paradigm in 25 older and 25 younger adults. Our results indicated that while younger adults demonstrated an increase in the activation of cortical regions responsible for maintaining attentional control in response to increased levels of conflict, such sensitivity and flexibility of the cortical regions to increased attentional control demands was absent in older adults. These results suggest a limitation in older adults’ capabilities for flexibly recruiting the attentional network in response to increasing attentional demands.     

Confidence judgments in real classroom settings: monitoring performance in different types of tests

During testing, students have a valuable opportunity to exercise and improve their self-regulatory skills. However, the extent to which they profit from those experiences may vary according to some personal, test-related, and environmental factors. This study investigated the effects of metacognitive skills and test types on students' test performances, confidence judgments, and on the accuracy of those judgments. A sample of 129 psychology undergraduate students (50 men and 79 women, mean age = 18.9 years) were categorized according to their metacognitive skills (high vs average vs low) and had their test performances and monitoring processes in two different types of tests (i.e., multiple-choice and short-answer tests) compared throughout one academic term. Their test preparation practices, along with their attributional and regulatory processes during test-taking, were also compared by using open-ended questions. The results showed that: (1) high-metacognitive students presented more effective test preparation practices, better test performances, and superior attributional, regulatory, and monitoring processes than their counterparts; (2) differences in performance and judgment accuracy were significantly larger in the short-answer tests than in the multiple-choice tests; and (3) over time, students' performances and confidence levels varied in specific patterns according to the type of test being taken. The results are discussed, focusing on the educational implications of the interactions observed and on how they may determine what students can learn from test-taking experiences. In addition, based on the results obtained, specific suggestions on how to increase the metacognitive awareness of university students through instruction and on how to improve their academic assessment are provided.     

Effects of Classwide Positive Peer “Tootling” to Reduce the Disruptive Classroom Behaviors of Elementary Students with and without Disabilities

The purpose of this study was to examine the use of a classwide positive peer reporting intervention known as “tootling” in conjunction with a group contingency procedure to reduce the number of disruptive behaviors in a third-grade inclusive classroom. Nineteen elementary students including four students with disabilities (i.e., specific learning disabilities and/or attention deficit hyperactivity disorder) were taught how to report their classmates’ positive behaviors using the “tootling” intervention. Results indicated that the use of the “tootling” intervention in combination with a group contingency procedure decreased students’ disruptive classroom behaviors, establishing a functional relation. Limitations of the study, implications for using tootling as a classwide positive behavior support, and future research questions are discussed.
