Thought dismissability in obsessive-compulsive disorder versus panic disorder

This study sought to better understand the persistence of obsessive-compulsive disorder (OCD) by studying the dismissability of obsessional thoughts in individuals with OCD relative to the dismissability of panic-relevant thoughts in individuals with panic disorder with or without agoraphobia (PD/A). Individuals with a principal diagnosis of OCD (n = 25) or PD/A (n = 25) completed a thought replacement task in which they replaced a primary obsession (target thought for the OCD group) or a primary panic-relevant thought (target thought for the PD/A group), with a neutral thought, signaling when the target thought occurred and when the neutral thought was in mind. The OCD group had more target thoughts and appraised the recurrence of the target thought more negatively. Whereas mood state did not change in the PD/A group, it declined in the OCD group, and this change was predicted by negative appraisal of target thought recurrences, but not amount of time thinking the target thought. These findings suggest that in vivo appraisal of the recurrence of obsessions may be a unique, key mechanism in the persistence of OCD and that the identification and exploration of appraisal of thought recurrences may be an especially important target in its treatment.     

Examining autobiographical memory content in patients with depression and anxiety disorders

The purpose of this study was to move beyond the traditional specificity model of autobiographical memory (ABM) and to examine the content of memories with a focus on disorder and schema-relevant content. The sample (N = 82) included 25 patients with major depressive disorder (MDD), 24 with social phobia (SP), and 33 with panic disorder with agoraphobia (PDA) who were referred to a large outpatient clinic for group treatment of depression or anxiety. Participants completed the Autobiographical Memory Test (AMT) and Beck Depression Inventory-II as part of the clinical intake process. Responses to the AMT were coded for disorder-specific content based on diagnostic criteria for each disorder as well as for schema-relevant (sociotropy vs. autonomy) content. A repeated measures multiple analysis of variance demonstrated significant differences in disorder-specific content, with patients in the MDD group reporting more depressotypic ABMs than those in the PDA group but not the SP group. Similarly, in the analysis of schema-relevant content, significant differences were found between MDD and PDA regarding the presence of autonomy-based ABM ratings. Study results provide partial support for the cognitive specificity hypothesis with ABM content. The results are discussed in relation to the cognitive models of depression and anxiety.     

We're all in this together now: group performance feedback to increase classroom team data collection

This study's primary goal was to evaluate the use of performance feedback procedures delivered to a classroom team to increase daily data collection. Performance feedback (PFB) was delivered to four classroom teams responsible for the daily collection of data representing student performance during prescribed instructional activities. Using a multiple-baseline design, the effects of the team performance-feedback were evaluated for the target student, and for generalization to data collection for all classroom students. A secondary question evaluated if student on-task behavior correlated with increased data collection. Finally, social validity was investigated to evaluate team satisfaction with the PFB intervention. The results demonstrate improved data collection across all four classroom teams for the target student in each classroom and generalization within classrooms to all remaining students. Slight increases in student on-task behavior were observed in three of the four classrooms, and teacher satisfaction ratings were high.     

The prolonged influence of subsequent context on spoken word recognition

Connine, Blasko, and Hall (Journal of Memory and Language 30:234–250, 1991) suggested that within a 1-second temporal window, subsequent biasing information can influence the identification of a previously spoken word. Four experiments further explored this hypothesis. Our participants heard sentences in which an ambiguous target word was followed less than or more than a second later by a word biased in favor of either the target word or another word. Overall, the effects of the contextual biases on responding, measured using phonemic restoration and phoneme identification, were almost as large after 1 second as before 1 second. The implications of these results for defining the window of contextual effects are discussed.     

Linking Religion and Spirituality with Psychological Well-being: Examining Self-actualisation, Meaning in Life, and Personal Growth Initiative

Research largely shows that religion and spirituality have a positive correlation to psychological well-being. However, there has been a great deal of confusion and debate over their operational definitions. This study attempted to delineate the two constructs and categorise participants into different groups based on measured levels of religious involvement and spirituality. The groups were then scored against specific measures of well-being. A total of 205 participants from a wide range of religious affiliations and faith groups were recruited from various religious institutions and spiritual meetings. They were assigned to one of four groups with the following characteristics: (1) a high level of religious involvement and spirituality, (2) a low level of religious involvement with a high level of spirituality, (3) a high level of religious involvement with a low level of spirituality, and (4) a low level of religious involvement and spirituality. Multiple comparisons were made between the groups on three measures of psychological well-being: levels of self-actualisation, meaning in life, and personal growth initiative. As predicted, it was discovered that, aside from a few exceptions, groups (1) and (2) obtained higher scores on all three measures. As such, these results confirm the importance of spirituality on psychological well-being, regardless of whether it is experienced through religious participation.     

Examining the Validity of Cyclothymic Disorder in a Youth Sample: Replication and Extension

DSM-IV-TR defines four subtypes of bipolar disorder (BP): bipolar I, bipolar II, cyclothymic disorder and bipolar not otherwise specified (NOS). However, cyclothymic disorder in children is rarely researched, or often subsumed in an “NOS” category. The present study tests the replicability of findings from an earlier study, and expands on the criterion validity of cyclothymic disorder in youth. Using the Robins and Guze (1970) framework we examined the validity of cyclothymic disorder as a subtype of BP. Using a youth (ages 5–17) outpatient clinical sample (N?=?894), participants with cyclothymic disorder (n?=?53) were compared to participants with other BP spectrum disorders (n?=?399) and to participants with non-bipolar disorders (n?=?442). Analyses tested differences in youth with cyclothymic disorder and bipolar disorder not otherwise specified who do, and those who do not, have a parent with BP. Compared to youth with non-bipolar disorders, youth with cyclothymic disorder had higher irritability (p?<?0.001), more comorbidity (p?<?0.001), greater sleep disturbance (p?<?0.005), and were more likely to have a family history of BP (p?<?0.001). Cyclothymic disorder was associated with a younger age of onset compared to depression (p?<?0.001) and bipolar II (p?=?0.05). Parental BP status was not significantly associated with any variables. Results support that cyclothymic disorder belongs on the bipolar spectrum. Epidemiological studies indicate that cyclothymic disorder is not uncommon and involves significant impairment. Failing to differentiate between cyclothymic disorder and bipolar NOS limits our knowledge about a significant proportion of cases of bipolarity.     

Visitor Usage of Digital and Physical Artifacts in Two Museum Programs

ABSTRACT

This article reports on a study designed to explore how digital and physical reproductions of original artifacts could be incorporated into museum programs that teach visitors about mechanical motion. Museum visitors were introduced to 3 different types of models through 2 different programs: an engineering design challenge and an exhibit interpretation exploring mechanical motion in every-day objects. Research, based on visitor observation and interviews (n = 79), explored how user interaction with the digital and physical models compared with interactions with the original artifacts, assessed what effect the integration of digital and physical models had on learning, and examined what the learning experience looked like for learners using the mechanisms in the museum activities. Analysis of the learning conversations in additional in-depth case studies (n = 8) for both programs provides a detailed look at how visitors integrated the 3 different model types into their group's experience. Results showed that visitors' usage of, attitudes toward, and learning from the three different types of mechanical models varied based on the visitor or educators' perceived value of the particular model, which was impacted by the context in which the objects were presented.     

Reflex Responses of Human Lip Muscles to Mechanical Stimulation During Speech

The role played by reflex pathways in the production of movement has been a significant issue for motor control theorists interested in a wide variety of motor behaviors. From studies of locomotion and chewing, it appears that gains in reflex pathways can be altered so that activity in these pathways does not produce destabilizing responses during movement. In speech production, recent experimental evidence has been interpreted to suggest that autogenetic lip reflexes (perioral reflexes) are suppressed during sustained phonation or speech production. The present study was conducted to assess the effects of phonation, direction of movement, and ongoing speech production on reflex responses of lip muscles. The present results suggest, in contrast to earlier work, that this reflex pathway is not suppressed during phonation or speech. However, the response may appear to be suppressed or absent because the amplitude of the observed response depends upon the activation levels of the various muscles of the lower lip and, therefore, indirectly on the nature of the gesture the subject is instructed to produce.
