Context and the allocation of resources in word recognition

Three experiments are reported that investigate the effects of context on the use of limited processing resources in word recognition. On each trial in all of the experiments, the subjects were presented with an incomplete sentence followed by a target display containing a word and two digits. In all cases, accuracy at reporting the word was affected by context, as expected. The effect of context on processing resources was examined by considering the accuracy of reports of the digits in cases in which the word did or did not fit the context. Accuracy of digit report was greater for digits surrounding words in related context, but only when the subjects were required to report the word before reporting the digits. There was no effect of word context on the digit report when subjects had to report the digits first. There was likewise no effect on accuracy of digit report when subjects were required to report only the word or only the digits, even when the cue was presented 250 msec after the target display was replaced by a patterned mask. The results suggest that the effect of context on the resources consumed in word recognition is restricted to aspects of processing that can be delayed until the subject is required to select an overt response, and a simple interpretation of the results may be given in terms of a slight modification of Morton's model of the interaction of stimulus information and context.     

Lessons learned in deep brain stimulation for movement and neuropsychiatric disorders

The introduction of deep brain stimulation (DBS) as a treatment for medication-refractory essential tremor in the late 1980s revealed, for the first time, that "chronically" implanted brain hardware had the potential to modulate neurologic function with surprisingly low morbidity. Over time, the therapeutic promise of DBS has become evident in Parkinson's disease and dystonia. In some experienced centers, complex tremor disorders, such as posttraumatic Holmes tremor and the tremor of multiple sclerosis, are being increasingly targeted. More recently, other indications, including obsessive-compulsive disorder, Tourette's syndrome, major depression, and chronic pain, have been proposed. As the field has expanded, our knowledge about potential cognitive side effects of DBS has also expanded. This article reviews the current knowledge regarding the impact of stimulation of the subthalamic nucleus, globus pallidus internus, and ventralis intermedius nucleus of the thalamus on symptoms in essential tremor, Parkinson's disease, and dystonia. Also discussed are the emerging targets, what is known about the cognitive sequelae of DBS, and what has been learned about the complications and therapeutic failures.     

An Overview of Directions in Psychotherapy Integration Research

In general, empirical research in psychotherapy integration has lagged behind the growing theoretical and clinical interest in the field. Even though many of the theoretically integrative treatment models currently available are based on empirical findings and clinical observations, the models themselves remain, for the most part, untested. Rigorous examination of integrative psychological theories and therapeutic programs is a necessary and useful way to increase our understanding of the process of psychotherapy and establish the efficacy and effectiveness of integrative therapies. The present article explores five different research areas in the field of psychotherapy integration, discussing several published studies in each area. The utility of this research for practicing clinicians is also discussed. Additional investigations in these areas and others are encouraged, with the goals of greater understanding of psychotherapy, as well as the further development and acceptance of integrative approaches.     

Optimism, coping, psychological distress, and high-risk sexual behavior among men at risk for acquired immunodeficiency syndrome (AIDS).

In a cohort of gay men responding to the threat of acquired immunodeficiency syndrome (AIDS), dispositional optimism was associated with less distress, less avoidant coping, positive attitudes as a coping strategy, and fewer AIDS-related concerns. Men who knew they were seropositive for human immunodeficiency virus (HIV) were significantly more optimistic about not developing AIDS than men who knew they were seronegative for HIV. This AIDS-specific optimism was related to higher perceived control over AIDS and to active coping among seropositive men only and to health behaviors in both serostatus groups. There was no relation of optimism to risk-related sexual behavior. It is concluded that optimism is psychologically adaptive without necessarily compromising health behavior. It is also concluded that it is useful to distinguish between event-based optimistic expectations and dispositional optimism.     

“Equal access” without “establishing” religion: The necessity for assessing social perspective-taking skills and institutional atmosphere

We concur withMoshman (1990) that in public high schools there should be unimpeded religious freedom if an empirical assessment shows students have the proficiency to evaluate and freely choose religious systems and practices and to discern attempts by authorities to establish a religion. We differ with Moshman,however, regarding (a) the relative importance of a school's ethical, moral and political climate in influencing the exercise of free religious and political choice; (b) his focus on religious over political freedoms; (c) what kinds of proficiencies need to be assessed; (d) how to assess these proficiencies; (e) his claim that that the reasoning ability of high school and college students is similar; and (f) the manner in which decisions permitting religious clubs in high schools should be made. Reasoning proficiency must be assessed in high school, as well as post-high school, populations of students, teachers, and administrators using a social perspective-taking task with establishment of a religion content. A school's institutional atmosphere must be assessed.     

AN EVALUATION OF EVIDENCE‐BASED INTERVENTIONS TO INCREASE COMPLIANCE AMONG CHILDREN WITH AUTISM

We evaluated 4 evidence‐based interventions to increase compliance. Three children with autism who exhibited noncompliance when asked to relinquish a preferred toy were exposed sequentially to interventions that included a reduction in response effort, differential reinforcement, and guided compliance. Results indicated that effort reduction alone was ineffective and that each participant's compliance improved after exposure to a different intervention; these results highlight the need to individualize treatments for compliance.     

Statistical equating with measures of oral reading fluency

Recent research on curriculum-based measurement of oral reading fluency has revealed important issues in current passage development procedures, highlighting how dissimilar passages are problematic for monitoring student progress. The purpose of this paper is to describe statistical equating as an option for achieving equivalent scores across non-parallel reading passages. The psychometric and design properties of words-correct scores are examined, and the requirements of traditional equating methods are discussed. Simulated and empirical words-correct scores are used to demonstrate the steps in the equating process and the situations in which each method is most appropriate.     

Personal Genomic Testing as Part of the Complete Breast Cancer Risk Assessment: A Case Report

Patient access and utilization of personal genomic testing is becoming increasingly common. We present a case of a patient's personal genomic screening results leading to early detection of infiltrating breast ductal cell carcinoma via MRI scan. This case exemplifies the successful integration of personal genomic testing into the primary care setting, with the guidance and support of genetic counseling services. We discuss the scientific basis of the patient's genome scan results and risk assessment, and how this informed her decision-making and subsequent screening. We also expound upon the role of personal genomic testing as compared to other screening tests in the complete breast cancer risk assessment.
