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.     

Developmental regulation before and after a developmental deadline: the sample case of "biological clock" for childbearing

This quasi-experimental research investigates developmental regulation around a critical life-span transition, the "biological clock" for childbearing. The action-phase model of developmental regulation proposes contrasting control orientations in individuals approaching versus those having passed a developmental deadline. Individuals in an urgency phase close to the deadline should be invested in goal pursuit, whereas those who have passed the deadline without attaining the goal should focus on goal disengagement and self-protection. In 2 studies, women at different ages and with or without children were compared with regard to various indicators of primary and secondary control striving for goal attainment versus goal disengagement and self-protection. Findings support the action-phase model of developmental regulation. Patterns of control striving congruent with the participants' status as pre- versus postdeadline were associated with superior psychological well-being.     

Early suicide following discharge from a psychiatric hospital

Social and clinical risk factors for completed suicide occurring shortly after discharge from a psychiatric hospital were examined in this case-control study. Seventy-seven individuals who received "suicide" or "undetermined death" verdicts at inquest, and who had been previously discharged from psychiatric hospitals in Bradford, U.K., were compared with a control group. A history of deliberate self-harm was significantly associated with early suicides compared with both late suicides and controls. A diagnosis of mood disorder, specifically depression, and longer case-notes were also significantly associated with early suicides compared to controls. This study has implications for risk management of recently discharged psychiatric patients.     

Similarities and differences in eyewitness testimonies of children who directly versus vicariously experience stress.

This study tested questions of ecological validity by comparing the eyewitness testimonies of children directly experiencing a painful inoculation experience those of children in a yoked-control group who vicariously experienced the inoculation onwith videotape. The study involved 86 5-year-olds, divided between 2 groups: the experiential and yoked control. The experiential group was followed through a health department with a video camera as they received diphtheria, pertussis, tetanus (DPT), and oral polio inoculations. They were tested immediately, 20 min later, and 1 month later. Each child in the yoked-control group merely watched the videotape of his or her counterpart in the experiential group, made similar ratings of pain, and was given the same tests and suggestions. Stress and personal experience affected items congruent with the stressor to produce flashbulb-like memories, with slower rates of forgetting for some items, such as nurse identifications, and greater suggestibility for other items, such as estimates of needle size. These and the apparently conflicting results in the literature were said to make sense when personally experienced stress was viewed from S.-A. Christianson's (1992) interactive perspective rather than as a single ubiquitous variable.     

Hierarchies, similarity, and interactivity in object recognition: "category-specific" neuropsychological deficits.

Category-specific impairments of object recognition and naming are among the most intriguing disorders in neuropsychology, affecting the retrieval of knowledge about either living or nonliving things. They can give us insight into the nature of our representations of objects: Have we evolved different neural systems for recognizing different categories of object? What kinds of knowledge are important for recognizing particular objects? How does visual similarity within a category influence object recognition and representation? What is the nature of our semantic knowledge about different objects? We review the evidence on category-specific impairments, arguing that deficits even for one class of object (e.g., living things) cannot be accounted for in terms of a single information processing disorder across all patients; problems arise at contrasting loci in different patients. The same apparent pattern of impairment can be produced by damage to different loci. According to a new processing framework for object recognition and naming, the hierarchical interactive theory (HIT), we have a hierarchy of highly interactive stored representations. HIT explains the variety of patients in terms of (1) lesions at different levels of processing and (2) different forms of stored knowledge used both for particular tasks and for particular categories of object.     

Twins dispute memory ownership: A new false memory phenomenon

In three experiments, we examined a new memory phenomenon: disputed memories, in which people dispute ownership of a memory. For example, in one disputed memory each of two twins recollected being sent home from school for wearing too short a skirt, although only one of them was actually sent home. In Experiment 1, 20 sets of same-sex adult twins were asked to produce a memory for each of 45 words, and most twins spontaneously produced at least one disputed memory. In Experiment 2,20 different sets of same-sex adult twins rated disputed memories as higher in recollective experience, imagery, and emotional reliving than nondisputed memories. In Experiment 3, siblings who were close in age as well as same-sex friends were also found to have disputed memories, but less often than twins.     

Parkinsonian Patients Reduce Their Stroke Size with Increased Processing Demands

Parkinson's disease (PD) patients often show reductions in writing size (micrographia) as the length of the text they produce increases. The cause for these reductions in stroke size are not well understood. Reductions in stroke size could be associated with either concurrent processing demands that result from the coordination and control of fingers, wrist, and arm during writing and the processing of future words or increased extension of the wrist joint as the execution of the writing progresses to the right across the page, resulting in increased stiffness in the pen-limb system. Parkinson's patients and elderly controls wrote phrases of different lengths with target patterns in various serial positions. When the number of words to be written increased, PD patients reduced their stroke size of the initial target pattern, while the elderly controls did not reduce their stroke size. There was no systematic change in stroke size of the second pattern as function of serial position. This result suggests that PD patients reduce the size of their handwriting strokes when concurrent processing load increases.     

Intimacy, Psyche, and Spirit in the Experience of Chinese and Japanese Calligraphy

In the West, we have adoped the word calligraphy to describe Chinese and Japanese writing out of the recognition that there is an aesthetic component inherent in the written characters. The author shows how Chinese and Japanese calligraphy is much more than writing; it must be approached as one would any piece of art. A brief history of Chinese and Japanese calligraphy is explored, including the elements and methods of brushwork and overall creation of the expressions themselves. The article concludes by looking at how calligraphy is a mode of self-discovery and self-development that opens us to a substantial dialogue between cultures and the paths of inner conversation.     

Religious Fundamentalism and Gender Differences

The role of religious fundamentalism and its relationship to shame and guilt was evaluated in 107 students who attend a church-sponsored university. A number of personality measures were given and gender differences were analyzed. The role of externalization was similar for males in this sample to that of earlier studies. However, it was found that females showed positive correlations between externalization and both shame and guilt. For females, more fundamentalistic religious training may help to contribute to an external orientation at the expense of identifying with a personal religion, and appropriate guilt.
