"It was never that bad": biased recall of grief and long-term adjustment to the death of a spouse

At 6 months following the death of their spouse, 37 participants reported their grief-related symptoms and thoughts, and then, approximately 4.5 years later, they attempted to recall how they felt at the time of the 6-month report. Although participants were far less distressed at recall than initially, they recalled their 6-month grief rather accurately. Participants did however overestimate prior grief-related intrusive ideation. Participant's current level of grief predicted what they recalled slightly better than the actual initial grief. Conversely, what they recalled predicted current levels of grief across various measures. Participants whose grief diminished relatively little over time tended to overestimate prior grief more. The retrospective reappraisal that one's past grief was not severe may indicate effective coping.     

Diagnostic differences in social anhedonia: a longitudinal study of schizophrenia and major depressive disorder

This study examined the hypothesis that, in schizophrenia, elevated trait social anhedonia (SA) is a stable individual difference, whereas in depression, increased SA is a reflection of a current clinical state that will diminish with recovery. Differences in trait Negative Affect (NA) and Positive Affect (PA) were also examined. Individuals with schizophrenia (n = 55) and depression (n = 34) were evaluated at baseline during hospitalization and compared with nonpsychiatric control participants (n = 41). Participants were assessed again at a 1-year follow-up. At baseline, compared with control participants, individuals with schizophrenia and depression were both characterized by elevated SA, greater NA, and lower PA. In schizophrenic individuals, elevated SA remained stable over the follow-up. However, in recovered depressed patients, SA declined over the follow-up period. Group differences remained in NA and PA over the 1-year follow-up. These results support the view that elevated SA is enduring in schizophrenia but that elevated SA is transiently related to clinical status in depression.     

Productive syntax abilities in Huntington's and Parkinson's diseases

This study examined syntactic changes in the spoken discourse of patients with Huntington's (HD) or Parkinson's disease (PD) and explored possible relationships between their syntactic changes and concomitant cognitive and motoric symptoms. Patient and control groups participated in a conversational discourse activity and completed a battery of standardized speech and cognitive tests. The HD group used shorter and fewer grammatically complete utterances than their healthy, age-matched peers, whereas there were no significant syntactic differences between PD patients and their healthy, age-matched peers or between PD and HD patients. Productive syntax abilities in HD and PD were meaningfully related to both neuropsychological and motor speech changes. These findings indicate that patients with subcortical disease, at least those with HD, may present with language production deficits and that these deficits are most likely the product of not only motor speech limitations (i.e., dysarthria) but also underlying cognitive impairments.     

Mental rotation of objects retrieved from memory: a functional MRI study of spatial processing

This functional MRI study examined how people mentally rotate a 3-dimensional object (an alarm clock) that is retrieved from memory and rotated according to a sequence of auditory instructions. We manipulated the geometric properties of the rotation, such as having successive rotation steps around a single axis versus alternating between 2 axes. The latter condition produced much more activation in several areas. Also, the activation in several areas increased with the number of rotation steps. During successive rotations around a single axis, the activation was similar for rotations in the picture plane and rotations in depth. The parietal (but not extrastriate) activation was similar to mental rotation of a visually presented object. The findings indicate that a large-scale cortical network computes different types of spatial information by dynamically drawing on each of its components to a differential, situation-specific degree.     

When the central executive lets us down: schemas, attention, and load in a generative working memory task

Participants were asked to generate a single sequence of numbers in between two bounds. By varying the requested sequence length and way in which the question is posed, this paradigm enables assessment of the contributions to central executive functioning of schema, focus of attention, and load. With sequences of three or four numbers, a quarter of the sample failed fully to comply with the instructions. They generated an incorrect number of numbers or went outside the specified bounds. With sequences of six numbers, more than half of the sample infringed one or more of the constraints. Participants consistently generated sequences with particular generic properties. The overall frequency and patterns of infringements suggest that a substantial proportion of participants focused their conceptual attention on sequence content and often neglected the problem of how thelength and boundary constraints were going to be evaluated either before or during response delivery.     

Alteration of mood state after a single bout of noncompetitive and competitive exercise programs.

This study evaluated the effects of three popular physical activities on the psychological well-being of university students. 44 students in three physical activity classes enrolled in the Fitness for Life Program at Montana State University which included circuit training, weight training, and racquetball were administered the Profile of Mood States scale 5 min. before and 5 min. after one bout of physical activity. Two of the three activities appeared to be associated positively with scores on certain subscales. The results supported positive psychological well-being of students after physical activity. Implications for research are presented.     

Response perseveration in psychopathic women.

Recent attempts to validate the Psychopathy Checklist-Revised (PCL-R) as a measure of psychopathy in female offenders have been limited by a failure to examine laboratory correlates of the syndrome. We assessed 112 incarcerated women by using the PCL-R and examined their performance on a card perseveration task that has been used to demonstrate response perseveration in psychopathic men. Contrary to prediction, psychopathic women did not perseverate responding when the PCL-R was used either dimensionally or categorically. The authors discuss the implications of the results for the PCL-R and for female psychopathy more generally.     

Disgust sensitivity and attitudes toward organ donation among African-American college students.

241 African-American college students (94 men and 147 women, mean age = 20.3 +/- 3.4 yr.) completed the 1994 Disgust Scale of Haidt, McCauley, and Rozin and a modified form of Parisi-Rizzo's 1987 Attitudes Toward Organ Donation Scale (negative subscale only) as well as a behavioral measure of intention to donate organs after death. Analyses indicated that the higher the disgust sensitivity, the more negative the attitude toward organ donation and the less likely the student was to indicate intent to donate organs. It was further shown that negative attitudes toward organ donation mediated the relationship between disgust sensitivity and the behavioral intention measure. Results highlight the complexity of the issues surrounding organ donation within an African-American population and provide additional empirical evidence for the development of a theoretical model to explain the organ donation phenomenon.
