Categorization in compulsive hoarding

Based on hypothesizing about the role of information processing, and in particular, underinclusive categorization in compulsive hoarding, this study examined categorization processes in people with clinically significant compulsive hoarding problems. Twenty-one participants with primary compulsive hoarding, 21 with OCD without hoarding, and 21 non-psychiatric controls completed three categorization tasks. Hoarding and OCD participants reported significantly more distress prior to each of the three tasks than did controls. On tasks sorting common household items, the groups did not differ on the number of piles created nor on the amount of time taken to sort. However, on a task sorting personally relevant items, hoarding participants took more time, created more piles, and reported more anxiety than non-psychiatric controls. Hoarders also took more time than the OCD group, and tended to create more piles. Hoarding severity was correlated with the number of piles created, but only when the objects were personally relevant. Results support under-inclusive categorizing for people with compulsive hoarding, but the effect was largely confined to objects of personal relevance.     

Testing assumptions of deliberate practice theory relevance, effort, and inherent enjoyment of practice with a novel task: study II

This study examined three assumptions of the theory of deliberate practice: that deliberate practice is perceived as relevant for improving performance and that it requires effort, but that it is not perceived as being inherently enjoyable. Of particular interest was how these perceptions change as practice difficulty changes. 30 college undergraduates practiced two different maze memorization and replication tasks and rated the practice relevance for improving performance on the task, the practice effort, and the inherent enjoyment of practice. The findings for each of the assumptions were consistent with those suggested by the theory and also showed that these perceptions are subject to the current performance on an activity and the difficulty of the practice.     

The Relationship Between Forgiveness and Borderline Personality Symptomatology

The relationship between forgiveness and borderline personality symptomatology has been rarely studied. Using a consecutive cross-sectional sample of 307 internal medicine outpatients and a survey methodology, we examined correlations between the Forgiveness Scale and borderline personality symptomatology as measured by the borderline personality disorder scale of the Personality Diagnostic Questionnaire-4 and the Self-Harm Inventory. Numerous forgiveness subscales as well as the composite Forgiveness Scale score demonstrated statistically significant relationships with both measures for borderline personality symptomatology, such that individuals with this personality pathology demonstrated lower scores on these forgiveness subscales. Findings indicate that among individuals with borderline personality symptomatology, there are numerous aspects of forgiveness that are significantly lower than in individuals without this symptomatology.     

Examining the Course of Suicidal and Nonsuicidal Self-Injurious Thoughts and Behaviors in Outpatient and Inpatient Adolescents

Suicidal and nonsuicidal self-injurious thoughts and behaviors (SITBs) among youth are major public health concerns. Although a growing body of research has focused on the complex association between nonsuicidal and suicidal self-injury, the temporal relationship between these two classes of behaviors is unclear. The current study addresses this empirical gap by examining the course of SITBs in adolescents receiving outpatient (N = 106; 82.1 % female) and inpatient (N = 174; 75.9 % female) treatment. SITBs (co-occurrence, age-of-onset, and time lag between SITBs) and major psychiatric disorders were assessed at a single time point with well-validated structured interviews. Adolescents in both clinical samples reported high co-occurrence of SITBs: most adolescents reported both lifetime nonsuicidal self-injury (NSSI) and suicidal thoughts. A similar temporal pattern of SITBs was reported in the two samples: thoughts of NSSI and suicide ideation had the earliest age-of-onset, followed by NSSI behaviors, suicide plans, and suicide attempts. However, the age-of-onset for each SITB was younger in the inpatient sample than in the outpatient sample. In terms of time lag between SITBs, suicide ideation occurred on average before initial engagement in NSSI, suggesting that pathways to NSSI and suicidal behavior may occur simultaneously rather than in succession from nonsuicidal to suicidal self-injury. Results also indicated that the time to transition between SITBs was relatively fast, and that a key period for intervention and prevention is within the first 6–12 months after the onset of suicidal thinking. Taken together, these findings have important implications for understanding the time-lagged relationship between nonsuicidal and suicidal self-injury.     

The missing fundamental in vowel height perception

Traunmüller (1981) suggested that the tonotopic distance between the first formant (F ₁) and the fundamental frequency (F ₀) is a major determinant of perceived vowel height. In the present study, subjects identified a vowel-height continuum ranging in formant pattern from /?/ to /ε/, at fiveF ₀ values. IncreasingF ₀ led to an increased probability of /I/ responses (i.e., the phoneme boundary shifted toward the /ε/ end of the continuum). Various conditions of filtering out the lower harmonics of the stimuli caused only marginal shifts of the phoneme boundary. The experiments provide evidence against interpretations of Traunmüller’s (1981) results that claim that vowel height is determined by the distance betweenF ₁ and the lowest harmonic that is present in the basilar membrane excitation pattern.     

Chronic suicidality and borderline personality

Suicidal ideation is a complex clinical event. In this article, acute suicidal ideation is compared with chronic suicidal ideation, specifically their different meanings, relationships with Axis I and Axis II disorders, intrapsychic functions, approaches to assessment, and interventions. The potential risks of acute hospitalization of the chronically suicidal borderline personality disorder patient are discussed as well as a longitudinal, multidimensional treatment strategy for the chronically suicidal individual.     

Shedding Light on the Relationship Between Personal Standards and Psychopathology: The Case for Contingent Self-Worth

Previous research has revealed some puzzling inconsistencies in the relationship of Personal Standards (PS) to measures of psychopathology. This study was designed to explore the hypothesis that setting high Personal Standards will relate to psychopathology only when meeting these standards is a necessary condition for a sense of self-worth. We generated items that reflected a sense of conditional self-worth based on the meeting of Personal Standards and named this measure the Contingent Self-Worth Scale (CSWS). Factor analysis of the CSWS and the PS subscale of the Multidimensional Perfectionism Scale yielded three types of Personal Standards: Pure Personal Standards," Success-Based Self-Worth," and Activity-Based Self-Worth." Two of the original PS items did not load on the Pure Personal Standards scale. Correlational analyses revealed that Pure Personal Standards was related to measures of adaptive outcome whereas both measures of Contingent Self-Worth were related to more maladaptive functioning, although with some small differences. We call for further research to explore the relationship of PS to the construct of perfectionism.     

Operationalizing the "vulnerability" and "stress" components of the hopelessness theory of depression: a multi-wave longitudinal study

The current study tested of the diathesis-stress component of the hopelessness theory (HT) using (1) a "weakest link" approach towards operationalizing vulnerability (e.g., an individual is as vulnerable to depression as his/her most depressogenic inferential style-DIS) and (2) an idiographic approach towards operationalizing high levels of stress. The procedure involved an initial assessment during which participants completed measures assessing DISs and depressive symptoms. The procedure also involved a series of eight follow-up assessments, occurring every 6 weeks, during which depressive symptoms and hassles were assessed. Hypotheses were tested in two samples of adults (i.e., adults diagnosed with a current MDE and adults diagnosed with a past MDE at Time 1). In line with hypotheses, in both samples, depressogenic weakest links were associated with greater elevations in depressive symptoms following elevations in hassles. At the same time, equally strong support was obtained for the HT when stress was operationalized from a nomothetic perspective and when vulnerability was operationalized as a DIS about causes (but not consequences or self).     

Internet chat room use, satisfaction with life, and loneliness

In this study, 50 chat room users responded online to the Satisfaction With Life Scale, the Revised UCLA Loneliness Scale, and demographic questions which included time spent per week in Internet chat rooms. Time spent in chat rooms was positively correlated with loneliness but only weakly and negatively related to satisfaction with life.     

The utility of psychological testing in assessing emotional damages in personal injury litigation

Psychological testing and assessment instruments frequently play a small but important role when psychologists assist the courts as emotional damage experts in personal injury matters. However, examiners frequently, if sometimes inadvertently, mislead the court with test interpretations that are based on clinical rather than forensic populations and that fail to appreciate the lack of robustness of clinical measures in this forensic context. Whereas published computerized interpretations repeatedly remind experts that personality test results should only be used as a method to generate hypotheses about the examinee that are to be subjected to further investigation and consideration, experts all too often inform the courts of test interpretations as if the test results were measures of clinical constructs rather than plaintiffs' self-reports of symptoms.
