Neuropsychological functioning in patients with borderline personality disorder

Although results have been variable, studies suggest that individuals with borderline personality disorder (BPD) exhibit cognitive deficits suggestive of frontal- and temporal-lobe dysfunction. Patients diagnosed with BPD (n = 18) using two structured interviews, and who were carefully screened for neurological and substance-use disorders, were compared to depressed patients (n = 18) and a nonpsychiatric control group (n = 18) on a series of neuropsychological tasks. The role of emotion on cognitive functioning was assessed by including emotional stimuli and interference on several of the tasks. Little support was found for the neurobehavioral hypothesis of BPD. The BPD group performance did not differ from the normal group on most tasks of executive functioning or memory, and the introduction of emotional stimuli did not impair performance. The depressed group performed less effectively than the other groups. Reasons for variable findings and factors affecting the cognitive functioning of patients with BPD are discussed. There may be considerable heterogeneity in the cognitive functioning of BPD patients, with those exhibiting significant cognitive deficits comprising only a subgroup.

Women and depression: An update on the report of the APA task force

This article reviews selected research on gender differences in depression in order to update the status of the literature and address concerns raised by the APA Task Force on women and depression. Recent research continues to provide considerable evidence that women experience higher rates of depression and that a variety of biological and psychological factors and their interactions must be considered to understand gender differences. Methodological issues including the need to define homogeneous subgroups, the effect of demographic variables, and sex bias in the diagnosis and measurement of depression are discussed. Conclusions are drawn that have implications for the prevention, identification and treatment of depression, and suggestions are made for research strategies.

Community recognition of objective and subjective characteristics of depression.

Assessed knowledge of depression in a random sample of 527 community-living adults. Vignettes were presented which described a young or old protagonist with depressive symptoms. Respondents were asked to identify potential problems and possible solutions. A depression information measure followed. Results indicated that community residents were aware of many objective features of depression although they identified less information about treatment issues. Older respondents were least informed. Although there were no gender differences in objective knowledge, men were less likely to mention depression with regard to the vignettes. Suggestions for implementing more effective community interventions are discussed.

The potential effects of the implanted memory paradigm on child subjects

The purpose of this article is to examine the appropriate use of the implanted memory paradigm with children. In this paradigm, participants are asked repeatedly about fictitious events that never transpired. The responses of children in these investigations demonstrate clearly that they can be led to unintentionally create false memories. This article addresses whether memory research should continue to encourage children to create memories for events that never happened. The literature in other areas of psychology suggests that deception may lessen respect for authority, affect a childs self-esteem, and create stress. We propose that the use of the implanted memory paradigm be suspended indefinitely or until appropriate research demonstrates that the paradigm does not affect children negatively.

Palmtop computerized reminding devices: the effectiveness of the temporal properties of warning signals

An intention requires us to carry out an action at a certain time or in an unscheduled time frame. In recent years, palmtop computerized devices with special functions have been developed that enable individuals to better remember their intentions. People record their intention in the device and are later reminded of their intention by a warning signal, such as an audible beep, that is presented along with a message about what is to be done. The present research investigated the psychological effects of the warning signals provided by palmtop reminding devices. Four experiments demonstrated that the effectiveness of an audible warning signal in the form of a signal was greatest early in the day. The interval between the signal and time to carry out the act, called here the anticipatory lag, did not significantly influence the timeliness of responses and remembering.

Inferring the Mental Processes of Other Minds

Abstract In 4 experiments, the authors examined how several variables influence the quality and quantity of information that people use to make judgments about other people. The results showed that when possible, participants consistently responded appropriately to variables that influenced information that they used to make inferences about other minds. The results also suggested that under circumstances with no opportunity to contrast behavior in different situations, people might not be sensitive to the quality and quantity of information present. The authors interpreted results to mean that under most circumstances, people make inferences in a way that efficiently uses information about the causes of behavior.

Cognitive functioning in the last year of life as a function of age, gender, and race.

Research has shown that many factors affect cognitive functioning. In this study cognitive functioning was analyzed using proxy reports concerning 17,135 decedents included in the 1993 National Followback Mortality Study conducted for the National Center for Health Statistics. These responses form a representative sample of all U.S. residents over age 15 who died in 1993 (except for those in South Dakota, which did not participate). Decedents had more difficulty understanding where they were than remembering what year it was or in recognizing family members. Logistic regression models found that age, gender, and race were the most important predictors of these basic cognitive functions. Although increasing age was associated with more cognitive difficulties, men had fewer deficits than women and Black Americans tended to have fewer deficits than White Americans. Possible reasons for these findings are discussed as well as some general implications for health service provision.Research has shown that many factors affect cognitive functioning.

A Proposed Role for Affect in Everyday Memory

Research efforts described in many of these chapters underscore the importance of studying everyday cognitive abilities. With an ear to public demands for greater research applicability and accountability, many investigators are seeking to better understand memory under naturalistic circumstances (Cohen, 1989). Empirical study of real-life cognitive processes is complicated by confounds that occur as a result of the limitations or absence of experimental controls. Much of what we know about basic cognitive processes, however, comes from controlled laboratory experiments, and these controlled experiments may provide a blueprint for exploring everyday cognitive processes.
