Expressed emotion in the client-professional caregiver dyad: are symptoms, coping strategies and personality related?

OBJECTIVE: The aim of this study was to investigate whether the characteristics of residents and professional caregivers are associated with the professionals' expressed emotion (EE). METHOD: Fifty-six residents in sheltered living who suffer from schizophrenia or a related psychotic disorder and their professional caregivers were enlisted. Standardised validated instruments were used to measure EE, the residents' social functioning, symptoms and social network size, and the professional caregivers' coping strategies and personality. RESULTS: There was strong evidence that high EE was associated with the residents' age, poorer social functioning and smaller network sizes. There was no significant relationship between EE and the residents' symptoms except for excitement. Concerning the professional caregivers, high EE professionals were less open than their low EE colleagues and had a lower education level. CONCLUSION: The residents' social functioning is an important correlate of the EE index.

Expressed emotion in staff-patient relationships: the professionals' and residents' perspectives.

BACKGROUND: Expressed emotion (EE) is a well-established, important predictor of the relapse rate of patients suffering from schizophrenia and other severe psychiatric disorders. EE measures the quality of the social interaction between a patient and his most important (in)formal caregiver. The aim of this study was to investigate the quality of the relationship in the staff-patient dyad as measured by the concept of EE. METHODS: EE was assessed using the Camberwell Family Interview (CFI, professionals) and the Perceived Criticism Scale (PCS, residents and professionals form) in a sample of 56 professional caregivers and their residents in nine sheltered living facilities in Flanders. RESULTS: Depending on the instrument, high EE was found to exist in one out of six (CFI) or one out of three (PCS) relationships. There was a significant positive correlation between the resident PCS and the critical comment scale of the CFI. CONCLUSIONS: The results of this study support the hypothesis that high levels of EE exist in some staff-resident relationships, which are mainly manifest as frequent critical comments and the presence of hostility. Emotional overinvolvement appears to be exceptional. Compared with the PCS, the CFI provides the most information about the quality of the relationship.

Categorization of novel stimuli in well-known natural concepts: a case study.

In this study, we investigated to what extent exemplar-based and prototype predictors can be applied to predicting categorization in natural language concepts. Participants categorized novel tropical foods into two well-known natural language concepts: fruits and vegetables. The results indicate that both the prototype predictors and the exemplar predictors contribute significantly in accounting for the categorization choices but that the contribution of the prototype predictor comes from just a limited number of features.

Predicting conjunction typicalities by component typicalities.

In two studies, we investigated to what extent typicalities in conjunctive concepts phrased as relative clauses--such as pets that are also birds--can be predicted from simple functions of constituent typicalities and from extensions of such functions. In a first study, analyses of a large aggregated data set, based on seven different experiments, showed that a calibrated minimum rule model and some extensions of this model accounted for a very large part of the variance in the conjunction typicalities. The same models can also account for the so-called guppy effect. A psychological explanation is presented, which states that typicalities in contrast categories, like pets that are not birds and birds that are not pets, further improve the prediction of conjunction typicalities. This hypothesis is tested in a second study.

Not guppies, nor goldfish, but tumble dryers, Noriega, Jesse Jackson, panties, car crashes, bird books, and Stevie Wonder.

This paper focuses on the guppy effect (Osherson & Smith, 1981), that is, on the existence of examples of conjunctive concepts that are more typical of the conjunction than of both constituents. The most frequently given examples of this effect, guppy and goldfish, are shown not to be more typical of the conjunction pet fish than of fish in two between-subjects and one within-subjects experiment. The frequency of the effect in a large empirical study is investigated, and better examples of the effect are suggested.

Dominance and noncommutativity effects in concept conjunctions: extensional or intensional basis?

Dominance and noncommutativity effects are investigated in relative clause descriptions of five conjunctive concepts (birds and pets, sports and games, vehicles and machines, office equipment and writing implements, and shoes and sports equipment). Both asymmetry phenomena are studied at the extensional level (using membership ratings) and at the intensional level (using feature-importance ratings). A clear dominance effect was found for both the membership ratings and the feature-importance ratings, whereas the noncommutativity effect emerged only occasionally in the membership ratings and almost never in the feature-importance ratings. The data suggested that the dominance effect and the much weaker noncommutativity effect have an extensional basis.
