Psychosis associated with anti-N-methyl-D-aspartate receptor antibodies

We describe the eighth case study of a female diagnosed with anti-N-methyl-D-aspartate receptor encephalitis without an identified tumor who presented with floridly psychotic symptoms following a 2-week prodromal phase with new-onset headaches and presyncopal episodes. While hospitalized, the patient had seizures, autonomic dysfunction, involuntary movements, and a decline in mental status. A subsequent assay was positive for anti-N-methyl-D-aspartate receptor receptor antibodies. In contrast to most reported cases, an initial trial with corticosteroids was therapeutically unsuccessful. Subsequent treatment with intravenous immunoglobulins, however, resulted in a prompt, robust clinical response and enabled the patient to be rapidly discharged from the hospital, with minimal neuropsychiatric sequelae.     

Endorsement of proactively aggressive caregiving strategies moderates the relation between caregiver mental health and potentially harmful caregiving behavior

This research tested the proposition that the oft-reported relation between caregiver mental health outcomes (i.e., resentment, depression) and potentially harmful caregiver behavior (PHB) would be mediated or moderated by caregiver endorsement of proactively aggressive caregiving strategies (PA). Caregiver resentment was the strongest predictor of PHB in the sample of 417 informal caregivers who resided with their care recipients; in fact, resentment mediated the impact of caregiver depression, thus suggesting that depressed affect was associated with PHB only if depressed caregivers resented their caregiving burdens. As predicted, caregiver endorsement of PA moderated the relation between resentment and PHB, such that links between these two constructs were strongest when caregivers were high in both resentment and PA. Endorsement of PA also mediated the relations between demographic or contextual variables (i.e., income, care recipient dementia) and PHB. Implications of these results for research and intervention are discussed.     

Influence of expressed emotion and perceived criticism on cognitive-behavioral therapy for social phobia

This study examined significant others' expressed emotion (EE) and a closely related construct, perceived criticism, as predictors of cognitive-behavioral therapy outcome in a sample of 40 patients with social phobia (social anxiety disorder). Patients enrolled in group therapy for social phobia completed pre- and post-treatment questionnaire measures of perceived criticism and anxious and depressive symptoms. Designated significant others were assessed for the components of high EE (criticism, hostility and emotional overinvolvement) using the Camberwell Family Interview. It was hypothesized that these high-EE components and patients' perceived criticism would be associated with poorer treatment outcome, and results ran counter to these expectations. Controlling for initial social phobia severity, lower levels of perceived criticism predicted treatment dropout. There was also a nonsignificant trend for participants with a significant other rated as high in emotional overinvolvement to show less change on a composite symptom measure. Findings from this study suggest that close relationships impact the outcome of cognitive-behavioral interventions for social phobia.     

Expressed emotion and familial interaction: a study with agoraphobic and obsessive-compulsive patients and their relatives

Patients with panic disorder with agoraphobia (n = 40) or obsessive- compulsive disorder (n = 61) participated in a 10-min problem-solving interaction with their primary relative. Relatives were categorized as hostile or nonhostile toward the patient on the basis of a measure of expressed emotion (EE). Observed interactions between patients and their hostile relatives, relative to those of dyads with a nonhostile relative, were marked by higher rates of relatives' criticism and of patients' negativity but not by higher rates of negative reciprocity. Analyses of sequences indicated that the dyads with a hostile relative had a higher rate of sequences in which the relative was first critical and the patient then negative than was the case for dyads with nonhostile relatives. Moreover, hostile relatives were more frequently critical than nonhostile relatives whether patients' preceding behavior was positive, negative, or neutral. The findings are consistent with the stress-vulnerability model of the effect of EE on mental health, in that patients living with a high EE relative appear to be exposed to higher levels of interpersonal stress.     

The development of memory for own- and other-race faces

This study demonstrates that experience and development interact to influence the "cross-race effect." In a multination study (n=245), Caucasian children and adults of European ancestry living in the United States, Norway, or South Africa, as well as biracial (Caucasian-African American) children and adults living in the United States, were tested for recognition of Asian, African, and Caucasian faces. Regardless of national or biracial background, 8- to 10-year-olds, 12- to 14-year-olds, and adults recognized own-race faces more accurately than other-race faces, and did so to a similar extent, whereas 5- to 7-year-olds recognized all face types equally well. This same developmental pattern emerged for biracial children and adults. Thus, early meaningful exposure did not substantially alter the developmental trajectory. During young childhood, developmental influences on face processing operate on a system sufficiently plastic to preclude, under certain conditions, the cross-race effect.     

The Effects of the <Emphasis Type="Italic">Nobody’s Perfect</Emphasis> Program on Parenting Resourcefulness and Competency

We conducted an evaluation of Nobody’s Perfect Program involving 71 participants from Peterborough County, Canada. Prior to the program, parents completed demographic information, along with self-report measures assessing the types of interactions with their children, parent resourcefulness, knowledge and use of resources, parent competency and self-efficacy, which were completed again after the program and at a two month follow-up testing. In comparison to parents not earning certificates, parents earning certificates were younger and more likely to have completed previous parenting programs. As well, parents earning certificates demonstrated and maintained an increase in parenting resourcefulness, warm/positive parent-child interactions, sense of parenting competency and satisfaction, and use of community resources. The more sessions parents attended, the better their parenting resourcefulness and warm/positive parent-child interactions on completion and at follow-up, and the less their angry and punitive parenting at follow-up. Parents who had attended parenting programs before had higher parenting resourcefulness scores at entry. They left the program with increased levels of parenting resourcefulness, better parent-child interactions, and more effective child management skills. A number of recommendations are suggested to help facilitators of the program enhance service delivery and improve parental outcomes.     

Self-report measures of child and adolescent psychopathy as predictors of offending in four samples of justice-involved youth

The authors examined the relation between self-report psychopathy measures and official records of offending in four samples of justice-involved youth (total N = 447). Psychopathy measures included the Antisocial Process Screening Device (APSD) and a modified version of the Childhood Psychopathy Scale (mCPS). Measures of offending included the total number of preadmission arrest charges for three samples (n = 392) and the total number of offenses in the year following release for two samples (n = 138). Neither measure was a strong correlate of preadmission offenses. Although mCPS scores were associated with postrelease offending in one sample, effects for the APSD were observed only when reoffending was conceptualized as a dichotomous variable, indicating a lack of robustness in this association. The findings suggest caution in the use of self-report measures of psychopathic features for decision making with respect to issues of delinquency risk among justice-involved youth.     

Mere exposure and the endowment effect on consumer decision making

Previous researchers (e.g., J. A. Bargh, 1992, 2002) demonstrated the importance of nonconscious processes on consumer choice behavior. Using an advertisement, the authors determined the effect of two nonconscious processes--the mere exposure effect, which increases object preference by increasing consumer exposure to an object, and the endowment effect, which increases object valuation by providing consumer possession of an object--on consumer behavior. Although the mere exposure effect and endowment effect did not produce an interaction, they produced independent effects. The endowment effect increased object valuation but not object preference. The mere exposure effect increased object preference but not object valuation. Thus, at the unconscious level, an increase in object preference does not lead to an increase in object valuation, nor does an increase in object valuation lead to an increase in object preference. The authors discuss the importance of developing measures of unconscious process in advertising effectiveness.     

A multinomial model for short-term priming in word identification.

A simple multinomial model for short-term priming in perceptual word identification is presented. In the experiments to which the model is applied, prime words are presented just prior to a flashed target word, and subjects must decide which of 2 alternative words matches the target. The model assumes that on some proportion of trials, confusion among the words leads to the decision being based on 1 of the prime words instead of the target. In addition, it is assumed that subjects sometimes discount a prime that matches 1 of the test alternatives and so choose the alternative that does not match. With these assumptions, the model fits the data from 5 experiments (including 4 used to develop the model known as ROUSE [responding optimally with unknown sources of evidence]; D. E. Huber, R. Shiffrin, K. Lyle, & K. Ruys, 2001). The multinomial model fits the data about as well as the ROUSE model and so should lead to further development and critical testing of both models.     

Synesthesia: Strong and Weak

In this review, we distinguish strong and weak forms of synesthesia. Strong synesthesia is characterized by a vivid image in one sensory modality in response to stimulation in another one. Weak synesthesia is characterized by cross-sensory correspondences expressed through language, perceptual similarity, and perceptual interactions during information processing. Despite important phenomenological dissimilarities between strong and weak synesthesia, we maintain that the two forms draw on similar underlying mechanisms. The study of strong and weak synesthetic phenomena provides an opportunity to enrich scientists' understanding of basic mechanisms involved in perceptual coding and cross-modal information processing.
