Effects of self-evaluation on the P300 event-related potential

The effects of self evaluation on the P300 event-related potential (ERP) were explored with 56 participants (16 men, 40 women; M age = 23.4 yr., SD = 1.2) across three conditions. The conditions included (1) a standard ERP auditory oddball discrimination between a random target (15% occurrence) and standard stimuli (85% occurrence), (2) the oddball task followed by the additional cognitive task of maintaining a mental count of the target tones, and (3) the oddball task followed by the additional cognitive task of self-evaluating whether they felt surprised by the current occurrence of the target tone. The added cognitive requirements for Conditions 2 and 3 required the subjects to maintain a cognitive readiness for the secondary stimulus-related task during their sensory discrimination response for the standard oddball task. During the self-evaluation condition, the P300 amplitude was significantly larger across all recording locations than the regular oddball condition and the cognitive count condition.     

Physician-patient relations: no more models

Currently, the common theoretical models of "preferred" decision-making relationships do not correspond well with clinical experience. This interview study of congestive heart failure (CHF) patients documents the variety of patient preferences for decision-making, and the necessity for attention to family involvement. In addition, these findings illustrate the confusion as to the designation of surrogate decision-makers and physicians in charge. We conclude that no single model of physician-patient decision-making should be preferred, and that physicians should first ask patients how they want medical information and decision-making to be handled.     

The cognitive-behavioural treatment of low self-esteem in psychotic patients: a pilot study

Low self esteem in individuals with a psychotic disorder is common and may be related to poorer clinical outcomes. However, there has been little research on devising treatment methods to improve self-esteem either generally or in psychotic patients in particular. The aims of this study were to evaluate the efficacy of a simple cognitive behavioural intervention to improve self esteem in psychotic patients who scored poorly on a self-esteem measure. This pilot study was a randomised control trial with a convenience sample of chronic psychotic inpatients. The cognitive behavioural self-esteem intervention, as an adjunct to treatment as usual (TAU), was compared to TAU alone in patients with psychosis. The individual self-esteem intervention as described by Tarrier (The use of coping strategies and self-regulation in the treatment of psychosis. (2001)) consisted of working with participants to elicit positive self-attributes and then identify specific behavioural examples to provide evidence of this attribute. Emphasis was given to any consequential change in the patient's belief that they had the attribute. The results indicated that this cognitive behavioural treatment for self-esteem used as an adjunct treatment in psychosis, resulted in clinical benefits in terms of increased self-esteem, decreased psychotic symptomatology and improved social functioning. These benefits were largely maintained at 3-month follow-up.     

Behavioral and personality characteristics of children with reactive attachment disorder

The authors compared behavioral and personality characteristics of children with reactive attachment disorder (RAD) with non-RAD children. Participants included parents of children with RAD (n = 21), parents of non-RAD children (n = 21), and some of the children (n = 20). The parents completed questionnaires regarding behavioral and personality characteristics of their children. Parents were also given the option of asking their children to participate in the study by completing self-report measures. Several significant findings were obtained. Children with RAD scored lower on empathy but higher on self-monitoring than non-RAD children. These differences were especially pronounced based on parent ratings and suggest that children with RAD may systematically report their personality traits in overly positive ways. Their scores also indicated considerably more behavioral problems than scores of the control children. Previous research has been generally qualitative in nature. The current research represents some of the first quantitative, empirical work documenting specific behaviors associated with the diagnosis of RAD. The findings of this study have implications for better understanding and dealing with reactive attachment disorder.     

Acquired equivalence and distinctiveness in human discrimination learning: evidence for associative mediation

In the first stage of Experiments 1-3, subjects learned to associate different geometrical figures with colors or with verbal labels. Performance in Stage 2, in which the figures signaled which of 2 motor responses should be performed, was superior in subjects required to make the same response to figures that had shared the same Stage 1 associate. A third stage of testing showed that the events used as associates in Stage 1 were capable of evoking the motor response trained in Stage 2, an outcome predicted by an associative interpretation of such transfer effects. Experiment 4 provided evidence that the relevant associations can be effective in controlling motor responding even when subjects report an antagonistic relationship between events.     

Correlated and coupled cognitive change in older adults with and without preclinical dementia

Common factor aging theories state that correlations among cognitive age effects signify a single underlying causal process. The logic underlying this proposition was evaluated by examining correlated cognitive change in a sample of 391 initially nondemented older adults who were tested annually for up to 16 years. Between-person correlations among rates of change (range = .56-.61) were partly attributable to model misspecification and the aggregation of heterogeneous groups of individuals. Correlated within-person cognitive change was much stronger in the cases (.45-.51) than in the noncases (.07-.18). These results demonstrate that correlated change may either signify causal commonality or the cumulative effects of multiple age-related conditions that can affect multiple cognitive systems.     

Empathy, Expectations, and Situational Preferences: Personality Influences on the Decision to Participate in Volunteer Helping Behaviors

Although considerable evidence indicates that dispositional empathy is associated with the degree of help that observers will offer needy targets, little is known about the effect of empathy on one's initial willingness to enter situations in which such needy targets might be found. Three studies were conducted to evaluate two related propositions: (1) that dispositional empathy influences such situational preferences, and (2) that this influence is mediated by the expectancies one holds regarding the emotions likely to occur in those situations. Using hypothetical judgments, Study 1 found support for both propositions. Study 2, in which participants believed that their responses actually committed them to encountering needy targets, provided further support for the model, as did Study 3, which examined the experiences of actual community volunteers. The theoretical and practical implications of these findings are discussed.     

Parental Goal Orientations and Beliefs About the Competitive-Sport Experience of Their Child1

We examined the achievement goals of parents' in relation to their interpretation of their child's sporting behavior, preference for certain types of performance feedback about their child, the types of tasks they prefer their child to engage in, and their beliefs about the cause of their child's performance. The sample consisted of 96 parents whose children were in the first year (mean age 11.3) at a large comprehensive school in a major city in the United Kingdom. Parents' dispositional achievement goal orientations were differentiated by their responses to the Perception of Success Questionnaire (Roberts & Balague, 1989, 1991). Whereas differences in task orientation appear to be critical in the education setting (Ames & Archer, 1988), the findings of this study suggest that individual differences in ego orientation may be more significant in the competitive sport context.     

Women and “body-isms” in television beer commercials

Research on women in print advertisements has shown that pictures of women's bodies and body parts (body-isms) appear more often than pictures of men's bodies. Men's faces (face-isms) are photographed more often than their bodies. This present study is the first to confirm this finding for television commercials. Results showed that men appear twice as often as women in beer commercials. The body-isms of women significantly outnumbered the body-isms of men. Women also appeared in swimwear more often than men, thus increasing the photo opportunities for body-isms. This study raises concerns about the dehumanizing influence of these images in beer commercials, and their association with alcohol use and the violence in the televised sporting events during which beer commercials are frequently aired.
