Borderline personality features and instability of daily negative affect and self-esteem

We used a daily process design and multilevel modeling to examine the role of borderline personality features in the day-to-day stability of college students' negative affect and self-esteem and their reactivity to interpersonal stressors. At the end of each day for two weeks, students completed a checklist of daily stressors and measures of state affect and self-esteem. We predicted that high scores on a measure of borderline features would be related to more daily interpersonal stressors, greater negative affective and self-esteem reactivity to these stressors, and less day-to-day carryover of negative mood and self-esteem. The first and third hypotheses were supported, but not the second. The findings demonstrate the utility of a daily process methodology and multilevel modeling to study the day-to-day functioning of individuals with borderline features.     

Childhood pay for grades is related to college grade point averages

In a sample of 87 college students from four junior level courses, being paid for earning good grades in childhood was related to higher college GPAs relative to students who were not paid for good grades in childhood.     

Nursing and psychological treatments

Presents a comment on "Psychological Treatments" by D. H. Barlow. In his article, Barlow pointed to the need "to solidify the identification of psychology as a health care profession" by changing the terminology of practice in the health care context from psychotherapy to psychological treatments and suggested that the only persons qualified to carry out such interventions are doctoral-level psychologists. Unfortunately, there was no discussion of the health care professionals who already provide psychological treatments in health care settings and their contribution to the evidence base supporting such treatment. The authors find several aspects of the article to be problematic. Overall, the authors feel that suggesting that psychology should claim treatment of psychological disorders and psychological components of physical disorders in health care settings as exclusively its own domain ignores the research and clinical contributions of others.     

Do behavioral disturbances in persons with Alzheimer's disease predict caregiver depression over time?

Random effects models were used to examine the association between behavioral disturbances in persons with Alzheimer's disease (N = 90) and caregiver depressive symptoms at 2-month intervals over an 18-month period. There was substantial variability in trajectories of change in caregiver depressive symptoms over time but no systematic increase in distress despite increased severity of dementia symptoms. Total behavioral disturbances were associated with higher levels of caregiver depressive symptoms: this effect was primarily attributable to aggressive behaviors. No consistent departure from linearity was evident in the relationship between behavior and depression over time.     

Preserved spatial memory over brief intervals in older adults

Two studies compared young and older adults' memory for location information after brief intervals. Experiment 1 found that accuracy of intentional spatial memory for individual locations was similar in young and older participants for set sizes of 3 and 6. Both groups also encoded individual locations in relation to the larger configuration of locations. Experiment 2 showed that like young adults, older adults' latency to respond to a test probe in a letter working memory task was negatively influenced by spatial information that was irrelevant to the task. This interference effect indicated preserved incidental memory for spatial information in older adults. Together, these data suggest that initial encoding of spatial information for relatively small numbers of items is largely preserved in healthy older adults and that representations of spatial information persist over short intervals.     

Levels of abstraction in orangutan (Pongo abelii) categorization

Levels of abstraction have rarely been manipulated in studies of natural concept formation in nonhumans. Isolated examples have indicated that animals, relative to humans, may learn concepts at varying levels of abstraction with differential ease. The ability of 6 orangutans (Pongo abelii) of various ages to make natural concept discriminations at 3 levels of abstraction was therefore investigated. The orangutans were rewarded for selecting photos of orangutans instead of humans and other primates (concrete level), primates instead of other animals (intermediate level), and animals instead of nonanimals (abstract level) in a 2-choice touch screen procedure. The results suggest that, like a gorilla (Gorilla gorilla gorilla) tested previously (Vonk & MacDonald, 2002), orangutans can learn concepts at each level of abstraction, and unlike other nonhumans, most of these subjects rapidly learned the intermediate level discrimination.     

Effectiveness of training in organizations: a meta-analysis of design and evaluation features

The authors used meta-analytic procedures to examine the relationship between specified training design and evaluation features and the effectiveness of training in organizations. Results of the meta-analysis revealed training effectiveness sample-weighted mean ds of 0.60 (k = 15, N = 936) for reaction criteria, 0.63 (k = 234, N = 15,014) for learning criteria, 0.62 (k = 122, N = 15,627) for behavioral criteria, and 0.62 (k = 26, N = 1,748) for results criteria. These results suggest a medium to large effect size for organizational training. In addition, the training method used, the skill or task characteristic trained, and the choice of evaluation criteria were related to the effectiveness of training programs. Limitations of the study along with suggestions for future research are discussed.     

Memory enhancement for emotional words: Are emotional words more vividly remembered than neutral words?

Individuals are more likely to remember negative information than neutral information. In the experiments reported here, we examined whether individuals were also more likely to remember details of the presentation of negative words, as compared with neutral words. In Experiment 1, the remember-know procedure was used to examine the effect of emotion on the vividness of an individual's memory, showing that remember responses were more frequently assigned to negative words than neutral words. In Experiment 2, a source memory paradigm was used, and again, evidence that individuals' memories were more detailed for negative than for neutral words was found. In Experiments 3-6, we examined the relative contribution of valence and arousal, finding that both dimensions increased the vividness of remembered information (i.e., items with valence only and those that elicited arousal were better remembered than neutral information) but that the effect was greater for words that evoked arousal than for those with valence only. The results support a qualitative, as well as a quantitative, memory benefit for emotional, as compared with neutral, words.     

Psychoeducation and managed care: Clinical issues for the 1990s

Managed care has challenged mental health professionals to develop more efficient ways of addressing patient care needs. Psychoeducational programs, for patients and their families, have emerged as a medium by which relevant education and mutual support can be provided to participants. A review of the literature, a comprehensive model of psychoeducation, and the advantages of such models within the managed care program are offered. Also addressed are issues and import, treatment and research considerations.     

Competition and recency in a hybrid network model of syntactic disambiguation

The competitive attachment model of human parsing is a hybrid connectionist architecture consisting of a distributed feature passing method for establishing syntactic relations within the network, and a numeric competition mechanism for resolving ambiguities, which applies to all syntactic relations. Because the approach employs a uniform mechanism for establishing syntactic relations, and a single competition mechanism for disambiguation, the model can capture general behaviors of the human parser that hold across a range of syntactic constructions. In particular, attachment and binding relations are similarly processed and are therefore subject to the very same influences of disambuguation and processing over time. An important influence on the competitive disambiguation process is distance within the network. Decay of numeric activation, along with distributed feature passing through the network structure, has an unavoidable effect on the outcome of attachment and binding competitions. Inherent properties of the model thus lead to a principled explanation of recency effects in the human parsing of both attachment and filler/gap ambiguities.
