Dreaming and hallucinations - continuity or discontinuity? Perspectives from dementia with Lewy bodies

Comparing the phenomenology, neurochemical pathology, and psychopharmacology of hallucinations and dreaming is limited by the available data. Evidence to date reveals no simple correspondence between the two states. Differences in the phenomenology of visual hallucinations and the visual component of dreams may reflect variations in visual context acting on the same underlying mechanism – the minimal visual input during dreaming contrasts with the more substantial perceived context in hallucinations. Variations in cholinergic, dopaminergic and serotonergic neurotransmitter function during sleep and during hallucinations in Lewy body dementias, together with relevant drug effects suggest that, on the whole, different, potentially opposite, changes characterise the two states. A similar analysis of other psychotic features in Lewy body dementia and other disorders suggests that, in contrast to hallucinations, there may be more convincing parallels between dreaming and delusional states.     

Relieving career anxiety and indecision: the role of undergraduate students’ perceived control and faculty affiliations

As educators and mentors, we often focus on helping undergraduate students make career decisions. However, there is also value in helping alleviate career anxiety and indecision, both of which impede decision-making and are not automatically resolved once a decision is made. This research examined the role of individual differences (age, gender, and perceived control) and learning environment variables (year in university, participation in an orientation program, and faculty affiliations) as predictors of undergraduates’ (n = 844) career-related anxiety and indecision. Traditional individual difference variables like age and gender had little effect whereas perceived control (primary and secondary) predicted lower levels of career anxiety and indecision. The outcomes were not influenced by environmental factors such as year in university or completion of an orientation program, but students’ self-reported faculty affiliation had significant effects. Students who were not affiliated with any specific faculty reported more indecision than students in arts, science, and professional faculties. Likewise, students in professional faculties had less career anxiety and career indecision than arts students. The implications of these results for potential interventions and future research are discussed.     

The DRC model of visual word recognition and reading aloud: An extension to German

The dual-route cascaded (DRC) model of word recognition and reading aloud was implemented in German. In this paper, we describe crosslinguistic differences and similarities between the German and the English DRC. The German DRC was evaluated with respect to its ability to correctly pronounce all German monosyllabic words and to simulate the loan word (regularity) effect. Furthermore, we obtained DRC predictions concerning a number of benchmark effects previously investigated in English, namely effects of word frequency, word length, and neighbourhood size.     

Validity and utility of computer-based test interpretation

Computers have been important to applied psychology since their introduction, and the application of computerized methods has expanded in recent decades. The application of computerized methods has broadened in both scope and depth. This article explores the most recent uses of computer-based assessment methods and examines their validity. The comparability between computer-administered tests and their pencil-and-paper counterparts is discussed. Basic decision making in psychiatric screening, personality assessment, neuropsychology, and personnel psychology is also investigated. Studies on the accuracy of computerized narrative reports in personality assessment and psychiatric screening are then summarized. Research thus far appears to indicate that computer-generated reports should be viewed as valuable adjuncts to, rather than substitutes for, clinical judgment. Additional studies are needed to support broadened computer-based test usage.     

Retrospective assessment of childhood sexual and physical abuse: a comparison of scaled and behaviorally specific approaches

This study compared retrospective reports of childhood sexual and physical abuse as assessed by two measures: the Childhood Trauma Questionnaire (CTQ), which uses a Likert-type scaling approach, and the Computer Assisted Maltreatment Inventory (CAMI), which employs a behaviorally specific means of assessment. Participants included 1,195 undergraduate students recruited from three geographically diverse universities. Agreement was high across the two measures in the classification of victim status (92% and 80% for sexual and physical abuse, respectively). However, the CTQ classified more participants as sexually abused than did the CAMI, whereas the opposite trend was found for physical abuse. For child physical abuse, many participants reporting abusive acts on the CAMI scored below the cut-point for physical abuse on the CTQ. Classification differences for both types of abuse were largely unrelated to demographic factors, socially desirable responding, or self-reported withholding of information. The implications of these results are discussed in light of future research using retrospective methods of assessing childhood abuse.     

A model for school psychology practice: addressing the needs of students with emotional and behavioral challenges through the use of an in-school support room and reality therapy

This article describes a treatment approach for students with emotional and behavioral challenges. The approach involves conducting reality therapy in an in-school support room. Data from this pilot study indicate that the treatment assists in developing more effective choices and in turn promotes cognitive and behavioral change in most students, while reducing the number of disciplinary actions for these students.     

Challenges of organizational learning: perpetuation of discrimination against employees with disabilities

This article examines why organizations struggle with learning how to prevent discrimination against their employees with disabilities. To explore this issue, qualitative archival data were collected and analyzed from 53 Americans with Disabilities Act (ADA) lawsuits filed against 44 organizations. Theoretical analysis of the qualitative data suggests that several organizationally based learning theories explain the difficulty organizations have with creating a disability-friendly work environment. These barriers to learning are embedded in complex defense mechanisms and discriminatory organizational routines. Furthermore, organizations have difficulties engaging in higher-order and vicarious learning. We conclude the article with examples of successful learning practices as they relate to barriers identified in the qualitative analysis.
