The Simple Copy Task: Detecting Higher Order Visual Processing Deficits in Schizophrenia,Dementia, and Movement Disorder Groups

The Simple Copy Task (SCT) is a figure copying test with inherent appeal due to its short administration time, graded task difficulty, varied stimuli, and potential to eliminate floor effects. Despite this, there is a lack of data regarding its construct validity and diagnostic utility. The present study compared SCT performance of schizophrenia (n = 29), dementia (n = 64), and movement disorder (n = 12) groups with that of unmatched healthy control participants (n = 49). Movement disorder patients committed a high degree of misplacement errors, whereas dementia patients tended to omit items, add extraneous detail, and perseverate. The schizophrenia group was most similar to the dementia group in their performance on the SCT, committing primarily omission and perseveration errors. The SCT was most closely related to the Rey Complex Figure Task (r = 0.68, p < .01) and the Block Design Task (r = 0.62, p < .01). Age (r = ?0.14, p < .01) and education (r = 0.35, p < .01) effects were present; however, there was no impact of gender and handedness. Taken together, these findings provide support for the utility of the task and directions for clinical interpretation.     

Can skilled readers perform a second task in parallel? A functional connectivity MRI study

When asked to search for a target letter while reading, the patterns with which people miss the target letter reveal information about the process of reading itself. Questions remain as to whether this paradigm reflects normal reading processes however. We used a novel continuous-performance neuroimaging paradigm to address this question. In separate scanning runs, subjects either read alone, read while searching for a target letter, or searched non-words continuously. Functional connectivity analysis recovered the full extent of brain areas identified for reading in a localizer scan, with no differences between reading alone and the dual task condition. Differences were found, however, between both reading conditions and the nonword search condition. These results demonstrate that in skilled readers brain activation associated with reading is unaffected by a concurrent letter-search task. They further demonstrate the utility of a naturalistic, continuous-performance paradigm for studying the neural basis of language processing.     

Exploring How Parents Make Sense of Change in Parent-Child Psychotherapy

Understanding how change occurs in psychotherapy is imperative in informing clinical practice. Increasing attention has been given to the role that qualitative research could play in enhancing our understanding of therapeutic change. Although quantitative research suggests that parent-child psychotherapy is effective in facilitating change, no research to date has focused on how parents make sense of their change experience. In this study, interpretative phenomenological analysis was used to analyze semi-structured interviews of eight parents who had completed parent-child psychotherapy about their understanding of change. Five master themes emerged that encapsulated participants’ understanding of change. These included constructing a survivor narrative, the experience of being understood enabling further understanding, adjusting expectations and practicing acceptance, and feeling empowered to relinquish control. The final theme summarized how despite psychotherapy being conceptualized as a “precious” resource, there was a sense that its limitations could negatively impact participant’s well-being.     

Urgency and negative emotions: Evidence for moderation on negative alcohol consequences

Prior research had shown that impulsivity may enhance the impact of negative emotions on alcohol related problems. However, these studies used broad measures of both negative emotions and impulsivity that may have obscured the effects of more specific constructs of impulsivity or negative emotions. One such construct is urgency, which is defined as the tendency to act impulsively in the face of strong positive emotions (positive urgency) or negative emotions (negative urgency). The present study tested whether urgency moderated the association between separate negative emotions (anger, depression and anxiety) and alcohol related problems. Data were obtained from a large online sample of currently drinking college students attending a large Northwestern university (n = 442). Findings indicated that alcohol related problems were directly associated with anger and both urgency facets. Additionally, positive urgency, but not negative urgency, enhanced the effects of depression, while the buffering effects of positive urgency on the anxiety-consequences association approached significance. These results suggest the importance of emotional context in understanding how dispositions towards rash action may lead to problematic alcohol use.     

Exploring urban students' constructions about school, work, race, and ethnicity

This qualitative study is an exploration of 32 urban high school students' narratives about the connection between school, work, and societal expectations of their future success related to their racial and ethnic background. The sample varied along 2 contextual dimensions: participation in a psychoeducational intervention (Tools for Tomorrow) and developmental status (i.e., half the sample were 9th-grade students and the other half were 12th-grade students). Using consensual qualitative research, the narratives revealed 3 major domains: future orientation; students' perceptions of society's expectations based on race and ethnicity; and students' perception of the role of their race and ethnicity in future success. Results reveal that the majority of students endorse a connection between school and work, believe that society holds low expectations for them based on their racial and ethnic background, and cannot predict their future success based on their background.     

The Autopsy Imperative: Medicine, Law, and the Coronial Investigation

The central purpose of this paper is to address the tension between legal and medical discourses within the coronial system. Medical expertise, based largely upon internal autopsy, becomes positioned as providing the more important information, rather than the legal model which focuses on evidence gathering at the scene. This paper will examine the aspects of the history, philosophy and consequences of the processes by which the medical model gained its current dominance and will conclude that, while autopsies are necessary, they are also over-used in the coronial system.     

Employees’ mood, perceptions of fairness, and organizational citizenship behavior

Previous research findings concerning employees’ perceptions of fairness and positive mood as predictors of organizational citizenship behavior (OCB) have been equivocal. Explanations for this inconsistency may be related to the varying types of manipulation techniques adopted and samples tested. To address these issues, the present study adopted the mood and fairness manipulation techniques of Bachrach and Jex (2000, Journal of Applied Psychology, 30(3), 641–663) to investigate their effect on OCB amongst a sample of 138 employees from five large service organizations. The findings revealed that employees’ perceptions of fairness affected their likelihood to perform organizational citizenship behaviors. One implication of this finding is that employees’ perceptions of fairness may have a more enduring effect, in comparison to their mood, on increasing their extra role work behaviors. However, a close evaluation of the mood manipulation technique suggests that further research is needed before any firm conclusions can be made on the relative effect of empolyees’ perceived fairness and positive mood on OCB.     

Social categorization and individuation in the own‐age bias

Young adults recognize other young adult faces more accurately than older adult faces, an effect termed the own‐age bias (OAB). The categorization‐individuation model (CIM) proposes that recognition memory biases like the OAB occur as unfamiliar faces are initially quickly categorized. In‐group faces are seen as socially relevant which motivates the processing of individuating facial features. Outgroup faces are processed more superficially with attention to category‐specific information which hinders subsequent recognition. To examine the roles of categorization and individuation in the context of the OAB, participants completed a face recognition task and a speeded age categorization task including young and older adult faces. In the recognition task, half of the participants were given instructions aimed to encourage individuation of other‐age faces. An OAB emerged that was not influenced by individuation instructions, but the magnitude of the OAB was correlated with performance in the categorization task. The larger the categorization advantage for older adult over young adult faces, the larger the OAB. These results support the premise that social categorization processes can affect the subsequent recognition of own‐ and other‐age faces, but do not provide evidence for the effectiveness of individuation instructions in reducing the OAB.     

The Role of Axioms in Mathematics

To answer the question of whether mathematics needs new axioms, it seems necessary to say what role axioms actually play in mathematics. A first guess is that they are inherently obvious statements that are used to guarantee the truth of theorems proved from them. However, this may neither be possible nor necessary, and it doesn’t seem to fit the historical facts. Instead, I argue that the role of axioms is to systematize uncontroversial facts that mathematicians can accept from a wide variety of philosophical positions. Once the axioms are generally accepted, mathematicians can expend their energies on proving theorems instead of arguing philosophy. Given this account of the role of axioms, I give four criteria that axioms must meet in order to be accepted. Penelope Maddy has proposed a similar view in Naturalism in Mathematics, but she suggests that the philosophical questions bracketed by adopting the axioms can in fact be ignored forever. I contend that these philosophical arguments are in fact important, and should ideally be resolved at some point, but I concede that their resolution is unlikely to affect the ordinary practice of mathematics. However, they may have effects in the margins of mathematics, including with regards to the controversial “large cardinal axioms” Maddy would like to support.
