Implementing the language comprehension test C-BiLLT: a qualitative description study using the COM-B model of behaviour change.

BACKGROUND: It is challenging to reliably assess the language comprehension of children with severe motor and speech impairments using traditional assessment tools. The Computer Based instrument for Low motor Language Testing (C-BiLLT) aims to reduce barriers to evidence-based assessment for this population by allowing children to access the test using non-traditional methods such as eye gaze so they can independently respond to test items. The purpose of this study is to develop a contextualized understanding of the factors that influenced clinicians' implementation of the C-BILLT in practice in the Netherlands and Norway. MATERIALS AND METHODS: A qualitative approach including semi-structured individual interviews with 15 clinicians (speech-language pathologists, neuropsychologists, and one teacher, counsellor, and vision specialist) was used. Data analysis was conducted in two rounds. First, a deductive approach including a codebook was used to code data within the COM-B components describing clinicians' capability, opportunity, and motivation for behaviour change. Then, an abductive approach applying thematic analysis was used to identify meaningful patterns within the COM-B components. RESULTS: Several meaningful barriers and facilitators were identified across the data. Clinicians used the C-BiLLT with two distinct groups of clients: (1) the population it was originally developed for, and (2) clients that could have also been assessed using a traditional language test. Clinicians working with the first group experienced more, and more complex barriers across all COM-B components, to successful C-BiLLT use than the latter. CONCLUSION: This study provides timely insights into the capability, opportunity, and motivation factors important for creating and sustaining assessment behaviour change in clinicians who used or attempted to use the C-BiLLT. Potential tailored intervention strategies aimed at improving implementation of novel assessment tools are discussed and may be helpful for others working to improve service delivery for children with complex needs.

An ambivalent alliance. Hostile and benevolent sexism as complementary justifications for gender inequality.

The equation of prejudice with antipathy is challenged by recent research on sexism. Benevolent sexism (a subjectively favorable, chivalrous ideology that offers protection and affection to women who embrace conventional roles) coexists with hostile sexism (antipathy toward women who are viewed as usurping men's power). The Ambivalent Sexism Inventory, first validated in U.S. samples, has been administered to over 15,000 men and women in 19 nations. Hostile and benevolent sexism are complementary, cross-culturally prevalent ideologies, both of which predict gender inequality. Women, as compared with men, consistently reject hostile sexism but often endorse benevolent sexism (especially in the most sexist cultures). By rewarding women for conforming to a patriarchal status quo, benevolent sexism inhibits gender equality. More generally, affect toward minority groups is often ambivalent, but subjectively positive stereotypes are not necessarily benign.

Beyond prejudice as simple antipathy: hostile and benevolent sexism across cultures.

The authors argue that complementary hostile and benevolent components of sexism exist across cultures. Male dominance creates hostile sexism (HS), but men's dependence on women fosters benevolent sexism (BS)--subjectively positive attitudes that put women on a pedestal but reinforce their subordination. Research with 15,000 men and women in 19 nations showed that (a) HS and BS are coherent constructs that correlate positively across nations, but (b) HS predicts the ascription of negative and BS the ascription of positive traits to women, (c) relative to men, women are more likely to reject HS than BS, especially when overall levels of sexism in a culture are high, and (d) national averages on BS and HS predict gender inequality across nations. These results challenge prevailing notions of prejudice as an antipathy in that BS (an affectionate, patronizing ideology) reflects inequality and is a cross-culturally pervasive complement to HS.

The motivated tactician's juggling act: compatible vs. incompatible impression goals.

This study examines how perceivers negotiate multiple, and sometimes incompatible, impression formation goals. Previous research typically presents perceivers with a single impression goal (e.g. accuracy, supporting preferred beliefs), and does not consider how perceivers juggle multiple goals. The processes of perceivers with multiple compatible goals should show uncomplicated impression formation processes, that is, strategic use of particular target attributes (e.g. negative) that suit their purposes. Perceivers with incompatible goals, in contrast, should be less selective, and form more complex impressions that reflect all types of attributes. In this experiment, perceivers with compatible goals paid less attention to target attributes, systematically biased their interpretation of those attributes, and ultimately formed less complex impressions than individuals with incompatible goals. How multiple impression goals are prioritized is discussed.

Controlling other people. The impact of power on stereotyping.

This article presents a theory of the mutually reinforcing interaction between power and stereotyping, mediated by attention. The powerless attend to the powerful who control their outcomes, in an effort to enhance prediction and control, so forming complex, potentially nonstereotypic impressions. The powerful pay less attention, so are more vulnerable to stereotyping. The powerful (a) need not attend to the other to control their own outcomes, (b) cannot attend because they tend to be attentionally overloaded, and (c) if they have high need for dominance, may not want to attend. Stereotyping and power are mutually reinforcing because stereotyping itself exerts control, maintaining and justifying the status quo. Two legal cases and a body of research illustrate the theory and suggest organizational change strategies.

Thinking is for doing: portraits of social cognition from daguerreotype to laserphoto.

From the outset, perspectives on social cognition have taken an emphatically pragmatic stance, as evident in early writing by James, Allport, Bruner, Asch, Heider, Tagiuri, and Jones. After a hiatus, during which social cognition research neglected its proper attunement to social behavior, researchers again are emphasizing that thinking is for doing, that social understanding operates in the service of social interaction. Early and recent (but not intermediate) theories have reflected a pragmatic orientation in 3 recurring themes: People are good-enough social perceivers; people construct meaning through traits, stereotypes, and stories; and people's thinking strategies depend on their goals. The pragmatic viewpoint again opens up new areas for research and theory in social cognition.

Personality feedback and situational norms can control stereotyping processes.

Impressions are influenced by motivations stemming primarily from the target (e.g., interdependence), 3rd parties (e.g., accountability or time pressure), or the self. The current studies investigate motivations stemming primarily from the self. In Study 1, Ss were given dispositional feedback about their abilities to categorize or to individuate. In Study 2, they were given situational information about the appropriate norms to categorize or to individuate. As predicted, dispositional feedback influenced low self-monitors, and situational information influenced high self-monitors. Both altered attention to potentially individuating category-inconsistent attributes as well as requests for additional information. Causal models further illuminated the mediating processes. These results suggest that people's flexible self-concepts are an important source of motivation in impression formation.

Circadian photoreception in the retinally degenerate mouse (rd/rd).

We have examined the effects of light on circadian locomotor rhythms in retinally degenerate mice (C57BL/6J mice homozygous for the rd allele: rd/rd). The sensitivity of circadian photoreception in these mice was determined by varying the irradiance of a 15 min light pulse (515 nm) given at circadian time 16 and measuring the magnitude of the phase shift of the locomotor rhythm. Experiments were performed on animals 80 days of age. Despite the loss of visual photoreceptors in the rd/rd retina, animals showed circadian responses to light that were indistinguishable from mice with normal retinas (rd/+ and +/+). While no photoreceptor outersegments were identified in the retina of rd/rd animals (80-100 days of age), we did identify a small number of perikarya that were immunoreactive for cone opsins, and even fewer cells that contained rod opsin. Using HPLC, we demonstrated the presence and photoisomerization of the rhodopsin chromophore 11-cis retinaldehyde. The rd/rd retinas contained about 2% of 11-cis retinaldehyde found in +/+ retinas. We have yet to determine whether the opsin immunoreactive perikarya or some other unidentified cell type mediate circadian light detection in the rd/rd retina.

Centrally administered cholecystokinin suppresses feeding through a peripheral-type receptor mechanism.

Agonists and antagonists selective for the brain-type [cholecystokinin (CCK)-B] and the peripheral-type (CCK-A) CCK receptor were used to localize the site(s) of action at which CCK inhibits food consumption. BC 264, a highly selective CCK-B receptor agonist, did not decrease consumption of a palatable meal when administered either i.p. or into the lateral ventricles of the brain, whereas CCK decreased feeding when administered i.p. at the same doses. CCK decreased feeding when administered i.v.t. at a high dose, 5 micrograms. L-364,718, an antagonist selective for the CCK-A receptor, blocked completely the action of centrally administered CCK, whereas L-365,260, a selective CCK-B receptor antagonist, had no effect on the ability of centrally administered CCK to inhibit feeding. To estimate the quantity of i.v.t. administered CCK which reached the periphery, a tracer of radiolabeled [3H]p-CCK8 ([3H]CCK octapeptide sulfate), combined with unlabeled pCCK8 (5 micrograms) was administered i.c.t. Thirty minutes after administration, intact radiolabeled pCCK8 was extracted from the plasma and measured in the blood in nanomolar concentrations, exceeding the amounts of CCK octapeptide sulfate reported previously to be present in the plasma after a meal. Intraventricularly administered CCK thus appears to reduce feeding in the rat through a mechanism involving a CCK-A receptor subtype in the periphery.

Confusing one person with another: what errors reveal about the elementary forms of social relations.

Seven studies investigated the cognitive structure of social relationships exhibited in the patterns of substitutions that occur when people confuse a person with another. The studies investigated natural errors in which people called a familiar person by the wrong name, misremembered with whom they had interacted, or mistakenly directed an action at an inappropriate person. These studies tested the relational-models theory of A. P. Fiske (1990b, 1991) that people use 4 basic models for social relationships. All 7 studies provide support for the theory; Ss tend to confuse people with whom they interact in the same basic relationship mode. In addition, Ss confuse people of the same gender. Other factors (age, race, role term, similarity of names) generally have smaller, less reliable effects, indicating that the 4 elementary modes of relationships are among the most salient schemata in everyday social cognition.

Activity of centrally administered galanin fragments on stimulation of feeding behavior and on galanin receptor binding in the rat hypothalamus.

Synthetic fragments of galanin 1-29 were administered intraventricularly or into the paraventricular nucleus of the hypothalamus for analysis of the critical amino acid sequence necessary to stimulate feeding behavior in rats. Galanin 1-29 and galanin fragment 1-16 significantly increased feeding at doses of 6 nmol microinjected into the lateral ventricles and 1 nmol microinjected into the hypothalamus. There was no significant effect of D-TRP2 galanin 1-16 microinjected into the hypothalamus, and no significant effect of galanin fragments 1-9, 10-20, 12-29, 17-29, or 21-29 microinjected intraventricularly, on food consumption. Synthetic fragments of galanin 1-29 were assayed for displacement of 125I-galanin 1-29 binding to rat hypothalamic membranes. The efficacies of the galanin fragments in the feeding paradigm were consistent with the relative affinities of these fragments for the hypothalamic galanin receptor in equilibrium binding experiments. The first 16 N-terminal amino acids appear to contain galanin agonist activity on increasing food consumption and to bind to the galanin receptor in the rat hypothalamus.

Interpersonal competition can cause individuating processes.

Two experiments investigated whether competitors attend to and individuate opponents. Interdependence theories predict that people individuate others on whom their outcomes depend rather than stereotyping them; this has been tested for cooperative but not for competitive interdependence. Competition separates such phenomena as unit formation in cooperation from interdependence per se, posited to be the crucial variable. In two experiments, Ss expected to compete or not compete with a competent or incompetent fictitious subject. Ss commented into a tape recorder about the person's attributes, some inconsistent and some consistent with expectations. As predicted, competitors (a) increased attention to inconsistencies, (b) drew more dispositional inferences about inconsistencies, and (c) formed more varied impressions. The role of competition in undercutting expectancy-based impressions and intergroup vs. interpersonal competition are discussed.

Motivational influences on impression formation: outcome dependency, accuracy-driven attention, and individuating processes.

How might being outcome dependent on another person influence the processes that one uses to form impressions of that person? We designed three experiments to investigate this question with respect to short-term, task-oriented outcome dependency. In all three experiments, subjects expected to interact with a young man formerly hospitalized as a schizophrenic, and they received information about the person's attributes in either written profiles or videotapes. In Experiment 1, short-term, task-oriented outcome dependency led subjects to use relatively individuating processes (i.e., to base their impressions of the patient on his particular attributes), even under conditions that typically lead subjects to use relatively category-based processes (i.e., to base their impressions on the patient's schizophrenic label). Moreover, in the conditions that elicited individuating processes, subjects spent more time attending to the patient's particular attribute information. Experiment 2 demonstrated that the attention effects in Experiment 1 were not merely a function of impression positivity and that outcome dependency did not influence the impression formation process when attribute information in addition to category-level information was unavailable. Finally, Experiment 3 manipulated not outcome dependency but the attentional goal of forming an accurate impression. We found that accuracy-driven attention to attribute information also led to individuating processes. The results of the three experiments indicate that there are important influences of outcome dependency on impression formation. These results are consistent with a model in which the tendency for short-term, task-oriented outcome dependency to facilitate individuating impression formation processes is mediated by an increase in accuracy-driven attention to attribute information.

Impaired mixed-lymphocyte culture reactions in patients with inflammatory bowel disease.

We studied the response of lymphocytes from 43 patients with inflammatory bowel disease to allogeneic stimulation in one-way mixed-lymphocyte cultures. We found that 53% of patients with inflammatory bowel disease, in contrast to 4% of normal and disease controls, had significant depression of mixed-lymphocyte culture response (P less than 0.01). The depression of mixed-lymphocyte culture response was independent of disease activity, duration (more or less than 10 yr), or presence of corticosteroid therapy. Removal of iron-ingesting mononuclear cells (macrophages) resulted in increased mixed-lmyphocyte culture response in 6 of 7 patients tested.
