Illness representations and matching labels with symptoms

Three studies are reported that show that health-relevant information (e.g., blood pressure [BP] or symptoms) initiates an active cognitive search process that results in the construction of an illness representation. Study 1 showed that informing subjects that their BP was elevated affected two attributes of illness representation: identity (label and symptoms), and time line or expected chronology of the health threat. Subjects given a high-BP reading reported symptoms commonly associated with high BP, especially if they attributed the high-BP reading to stress. Study 2 showed that the active search process uses causal information (a third attribute of representations) to give meaning to symptoms. Specifically, subjects used environmental cues to interpret whether familiar, unfamiliar, and ambiguous symptoms were due to illness or to stress. In Study 3 we showed that the constructive process, initiated by a high-BP reading, is directed by prior beliefs about the time line for developing high BP and by the presence of external cues about the stressfulness of the subject's daily life. Subjects who believed BP was labile and that they were under high daily stress or who believed BP was stable and that they were under low daily stress reported more symptoms. The significance of these findings for understanding how people process diagnostic labels and symptom information involved in the construction of illness representations is discussed.     

Gender-related effects in the perception of anger expression

The purpose of the study was to investigate the influence of sex of stimulus person, sex type of subject, and sex of subject on the social perception of anger expression. One hundred and sixty-six female and 100 male subjects completed a questionnaire that consisted of 10 vignettes depicting the expression of anger by either a female or a male stimulus person. For each vignette, subjects rated the psychological balance, expected frequency of behavior, perceived degree of anger, and appropriateness of behavior. Overall, female stimulus persons were rated higher on all dependent measures, but only male raters significantly differentiated between male and female stimulus persons. Generally, female subjects gave higher ratings, but viewed angry behavior as less appropriate than did male subjects. Ratings were also found to be related to subjects' scores on Extended Personal Attributes Questionnaire scales that involved socially undesirable traits. Post hoc analysis indicated that the type of anger response (“aggressive” or “nonaggressive”) was also an important variable, especially for the female subjects.     

The Rotter Locus of Control Scale in 43 Countries: A Test of Cultural Relativity

A databank of 9140 responses to the Rotter (1966) locus of control scale was analyzed, using multidimensional scaling techniques. Respondents were employees in business organizations in 43 countries. Three interpretable dimensions were identified. The first was interpreted in terms of Schwartz's (1992) dimensions of mastery over the environment versus harmony with the environment. It also correlated significantly with country means for internality. The second distinguished responses from countries identified by Hofstede (1980) as individualist and collectivist. The third referred principally to the role of luck and chance. Parallels with the results of Levenson (1981) and the implications of convergence with the results of cross-cultural studies not based upon the concept of locus of control are discussed.     

Visual discrimination learning in the killer whale (Orcinus orca)

Trial-and-error and errorless training procedures were used to train two killer whales on a simple visual discrimination problem. Both whales demonstrated difficulties in solving the problem under trial-and-error training. The relative effectiveness of the two training procedures is evaluated.     

Trait Forgiveness and Dyadic Adjustment Predict Postnatal Depression

The birth of a first child can be stressful on intimate partner relationships and the women having their first child. Conflict can occur, and hurts might be experienced, which could lead to post-partum depression. Thus, capacity for forgiveness with specific hurts might affect post-partum depression. We investigated women having their first child (N?=?52), and examined whether dyadic adjustment, trait forgiveness, and situational forgiving during pregnancy predicted postpartum depression. This study found that marital forgiveness predicted lower levels of depression above and beyond the effects of general dyadic adjustment. Dyadic adjustment and trait forgiveness predicted postpartum depression while situational forgiving was mixed. Postpartum depression researchers are encouraged to consider the inclusion of positive psychology variables, such as forgiveness, in future research studies.     

Dissociation in self-narrative

We review different analytic approaches to narratives by those with psychopathological conditions, and we suggest that the interpretation of such narratives are complicated by a variety of phenomenological and hermeneutical considerations. We summarize an empirical study of narrative distance in narratives by non-pathological subjects, and discuss how the results can be interpreted in two different ways with regard to the issue of dissociation.     

Visual cognition influences early vision: the role of visual short-term memory in amodal completion

A partly occluded visual object is perceptually filled in behind the occluding surface, a process known as amodal completion or visual interpolation. Previous research focused on the image-based properties that lead to amodal completion. In the present experiments, we examined the role of a higher-level visual process-visual short-term memory (VSTM)-in amodal completion. We measured the degree of amodal completion by asking participants to perform an object-based attention task on occluded objects while maintaining either zero or four items in visual working memory. When no items were stored in VSTM, participants completed the occluded objects; when four items were stored in VSTM, amodal completion was halted (Experiment 1). These results were not caused by the influence of VSTM on object-based attention per se (Experiment 2) or by the specific location of to-be-remembered items (Experiment 3). Items held in VSTM interfere with amodal completion, which suggests that amodal completion may not be an informationally encapsulated process, but rather can be affected by high-level visual processes.
