Divergent and Convergent Group Creativity in an Asynchronous Online Environment

This study examined the influence of various group diversity dimensions on collaborative creativity related to the healthcare system. Research findings on the association between diversity and brainstorming performance has been mixed. Diversity that increases cognitive stimulation or promotes elaboration has been shown to increase group performance. Participants exchanged ideas, replied, and elaborated using an electronic discussion board in an asynchronous fashion in groups of five over a period of 4 weeks. The groups varied in diversity of ethnicity, gender, age, and political orientation, but participants were not made aware of this diversity. Age and gender diversity were related to lower levels of replying to ideas and lower idea novelty but political diversity was related to increased replies and novelty. If a topic engages people with different perspectives to actively respond to others’ ideas, this can increase the creative potential of idea sharing in groups. Political or value-based diversity has the potential for creative solutions if the other participants’ political or value-based identities are not made salient.     

Conceptual,methodological, and clinical issues in the assessment of anxiety disorders

Many conceptual, methodological, and clinical issues remain unresolved in the assessment of anxiety disorders. Despite the prevalence, incidence, chronicity, and severity of anxiety disorders, research efforts and funding have fallen behind with regard both to other disorders and to addressing critical issues in the field. The primary objective of this paper is to provide a scientific critique regarding a number of often ignored yet salient considerations in anxiety-disorders assessment. Critical analyses of and recommendations regarding the multidimensional nature of anxiety, comorbidity, uniformity myths, synchrony, normative comparisons, psychometric properties of measures, and treatment integrity are offered. Finally, promising areas of clinical research are presented to enhance further the current understanding of the complexities inherent in assessing anxiety disorders.Preparation of this paper was supported in part by NIMH Grant MH36299.     

Reinforcer pathology,probabilistic choice,and medication adherence in patients with multiple sclerosis

The reinforcer pathology model posits that core behavioral economic mechanisms, including delay discounting and behavioral economic demand, underlie adverse health decisions and related clinical disorders. Extensions beyond substance use disorder and obesity, however, are limited. Using a reinforcer pathology framework, this study evaluates medical adherence decisions in patients with multiple sclerosis. Participants completed behavioral economic measures, including delay discounting, probability discounting, and a medication purchase task. A medical decision-making task was also used to evaluate how sensitivity to mild side effect risk and efficacy contributed to the likelihood of taking a hypothetical disease-modifying therapy. Less steep delay discounting and more intense (greater) medication demand were independently associated with greater adherence to the medication decision-making procedure. More generally, the pattern of interrelations between the medication-specific and general behavioral economic metrics was consistent with and contributes to the reinforcer pathology model. Additional research is warranted to expand these models to different populations and health behaviors, including those of a positive health orientation (i.e., medication adherence).     

Contributions of survey research to the understanding of memory

This article reviews the results of survey methodological research that illustrate phenomena of potential interest to investigators of memory, and also reviews psychological research designed to explore some of these phenomena under controlled laboratory conditions. We classify the phenomena reviewed into broad categories of remembering what events occurred, remembering when events occurred, and estimation and reconstruction processes used in reporting recurring events. We delineate the contributions of this research for our understanding of memory phenomena and show where this research has revealed gaps in our existing theories and knowledge. These findings present challenges for future collaboration between cognitive psychologists and survey methodologists.     

Panic disorder: cognitive-behavioral treatment

The effectiveness of an integrated treatment program utilizing cognitive-behavioral therapies for Panic Disorder was examined. Treatment was comprised of Cognitive Model of Panic-derived procedures, Cognitive Therapy and Applied Relaxation Training. Subjects meeting DSM-III-R criteria for Panic Disorder received thirteen 2.5-hr sessions of outpatient therapy in small groups, over a 12-week period. Subjects were given an extensive rationale of the etiology, development and maintenance of Panic Disorder, within the framework of the Cognitive Model of Panic, and controlled behavioral experiments in panic evocation to internal panicogenic cues, cognitive reappraisal of somatic and ideational cues, breathing retraining, Applied Relaxation Training and Cognitive Therapy to identify and remediate maladaptive beliefs and dysfunctional cognitive schemas. A comprehensive assessment battery was given at pre-mid-post-treatment which included measures of tripartite functioning, global severity, panic, fear, anxiety, depression and psychiatric symptomatology. Analyses indicated statistically significant improvements across all outcome domains. All subjects were free of spontaneous (uncued) panic attacks at post-treatment, and all met operationalized criteria for high endstate functioning. These findings are discussed, with recommendations for future research.     

Psychophysiological outcome of cognitive, behavioral and psychophysiologically-based treatments of agoraphobia

Psychophysiological process and outcome phenomena were analyzed to examine differential temporal patterns within and across cognitive, behavioral and physiologically-based treatments of agoraphobia. Eighty-eight severe and chronic agoraphobics with panic attacks (DSM-III) were randomly assigned to one of three treatments: Paradoxical Intention, Graduated Exposure or Progressive Deep Muscle Relaxation Training. Protocol therapists, whose treatment integrity was objectively monitored, conducted 12 two-hour weekly sessions. All subjects received programmed practice instructions concurrent with their primary treatment. Analyses revealed numerous significant reductions on in vivo psychophysiological measures for the relaxation condition, a few improvements for the exposure treatment and no effects for the paradoxical intention modality. The mediating role of pretreatment physiological reactivity in treatment outcome and follow-up status was examined and revealed no significant associations. Synchrony-desynchrony patterns were found to vary widely according to both treatment phase and the time interval between assessments. No between-group differences were observed on the proportion of synchronizers. However, synchronizers exhibited superior outcome and follow-up compared to desynchronizers on all domains except the physiological measures. Conceptual, methodological and clinical implications of these findings are discussed with recommendations for future research.     

Naming multisyllabic words

The process of reading multisyllabic words aloud from print was examined in 4 experiments. Experiment 1 used multisyllabic words that vary in terms of the consistency of component spelling-sound correspondences. The stimuli were regular, regular inconsistent, and exception words analogous to the monosyllabic items used in previous studies. Both regular inconsistent and exception words produced longer naming latencies than regular words. In Experiment 2 these differences between word types were found to be limited to lower frequency items. Experiment 3 showed that effects of number of syllables on naming latency are also limited to lower frequency words when the stimulus display forced subjects to use syllabic units. Thus, frequency modulates the effects of two aspects of lexical structure-consistency of spelling-sound correspondences and number of syllables. The results suggest that the naming of multisyllabic words draws on some of the same knowledge representations and processes as monosyllabic words; however, naming does not require syllabic decomposition. The results are discussed in the context of current models of naming.
