Emotional valence and reference disturbance in schizophrenia.

The authors examined the impact of emotional valence on reference disturbance in patients with schizophrenia and identified factors that moderate individual differences in this relationship. Thirty-nine patients with schizophrenia were given an interview that elicited speech samples in response to 10 neutral and 6 negatively valenced emotional questions. Speech samples were analyzed using the Communication Disturbances Index (N. M. Docherty, M. DeRosa, & N. C. Andreasen, 1996). Participants were also assessed with the Positive and Negative Symptom Scale (S. Kay, 1991) and a single-trial Stroop task (Stroop, 1935). Group analyses indicated that negative questions elicited more unclear references than neutral questions. Both the severity of disorganization symptoms and selective attention deficits predicted increased reference errors in response to emotional questions.

Expectancy changes in depression and schizophrenia.

Does the learned helplessness model of depression apply to clinically depressed patients and is it specific to depression? Changes in expectancy following success and failure in skill and chance tasks were assessed for depressed nonschizophrenics (unipolar depressives), depressed schizophrenics, nondepressed schizophrenics, and normal controls (32 Ss, aged 18–50 yrs). Unipolar depressives showed smaller changes in expectancy of future success after failure in the skill task than did the controls and both schizophrenic groups. Depressed schizophrenics did not show smaller expectancy changes than nondepressed schizophrenics. The learned helplessness model has been tested primarily in populations with subclinical depression; the present results provide partial support for learned helplessness as a model of one type of severe clinical depression and suggest that learned helplessness is not a general feature of psychopathology.

MMPI—2 findings in schizophrenia and depression.

Minnesota Multiphasic Personality Inventory—2 profile differences between patients with a discharge diagnosis of schizophrenia (n?=?42) vs. depression (n?=?42) were investigated. Multivariate analyses of variance indicated significant multivariate effects associated with diagnosis for the basic validity and clinical scales and for the content scales. The depression group obtained significantly higher mean scale scores on Scales 2 (Depression), 4 (Psychopathic Deviate), 7 (Psychasthenia), O (Social Introversion), Anxiety, Depression (DEP), and Social Discomfort. In an attempt to replicate work by Y. S. Ben-Porath, J. N. Butcher, & J. R. Graham (1991), a stepwise multiple regression analysis was performed to predict diagnosis, with similar findings obtained. Scale 2 was identified as the 1 significant clinical scale predictor. Two content scales, DEP and Bizarre Mentation, were identified as contributing significantly to prediction beyond Scale 2. When the order of the analysis was reversed, none of the basic clinical and validity scales contributed beyond prediction afforded by the content scales.

Emotional reactivity to daily events in major and minor depression.

Although emotional dysfunction is an important aspect of major depressive disorder (MDD), it has rarely been studied in daily life. Peeters, Nicolson, Berkhof, Delespaul, and deVries (2003) observed a surprising mood-brightening effect when individuals with MDD reported greater reactivity to positive events. To better understand this phenomenon, we conducted a multimethod assessment of emotional reactivity to daily life events, obtaining detailed reports of appraisals and event characteristics using the experience-sampling method and the Day Reconstruction Method (Kahneman, Krueger, Schkade, Schwarz, & Stone, 2004) in 35 individuals currently experiencing a major depressive episode, 26 in a minor depressive (mD) episode, and 38 never-depressed healthy controls. Relative to healthy controls, both mood-disordered groups reported greater daily negative affect and lower positive affect and reported events as less pleasant, more unpleasant, and more stressful. Importantly, MDD and mD individuals reported greater reductions in negative affect following positive events, an effect that converged across assessment methods and was not explained by differences in prevailing affect, event appraisals, or medications. Implications of this curious mood-brightening effect are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Implicit memory for spatial context in depression and schizophrenia.

Deficits in explicit spatial memory, as well as abnormalities of the hippocampus and neighboring medial temporal structures, have been documented in schizophrenia and depression. Recent evidence relying on the contextual cueing paradigm has shown that integrity of these structures is crucial not only for explicit memory but also for implicit spatial memory. Using this paradigm, the authors show that implicit memory for spatial context is severely impaired in clinically depressed patients but reaches a normal level in schizophrenia patients, although in these patients, acquisition is slower than in controls. By contrast, implicit memory for isolated locations and colors is normal in both schizophrenia and depressed patients. These findings suggest an implicit memory impairment specific to spatial context in depression. The implications for research on the differences between schizophrenia and depression in abnormalities of the hippocampal system and for research on the neural correlates of contextual cueing are discussed.

Premorbid adjustment and affective expression in schizophrenia.

Randomly selected 2 samples composed of 25 process and 25 reactive schizophrenics. There were no significant differences among the groups either in mean age or education. Mmpi deviation scores were obtained for each s by subtracting s's mean clinical scale score from each of the 9 mmpi clinical scales. Reactive ss had significantly (p     

Emotional expression modulates perceived gaze direction.

Gaze perception is an important social skill, as it portrays information about what another person is attending to. Gaze direction has been shown to affect interpretation of emotional expression. Here the authors investigate whether the emotional facial expression has a reciprocal influence on interpretation of gaze direction. In a forced-choice yes-no task, participants were asked to judge whether three faces expressing different emotions (anger, fear, happiness, and neutral) in different viewing angles were looking at them or not. Happy faces were more likely to be judged as looking at the observer than were angry, fearful, or neutral faces. Angry faces were more often judged as looking at the observer than were fearful and neutral expressions. These findings are discussed on the background of approach and avoidance orientation of emotions and of the self-referential positivity bias.

Emotional expression and physiology in European Americans and Hmong Americans.

Ethnographic and clinical observations suggest that Asians are less expressive than European Americans. To examine whether this difference emerged in online emotional responding, 50 Hmong Americans (HAs) and 48 European Americans (EAs) were asked to relive past episodes of intense happiness, pride, love, anger, disgust, and sadness. Facial behavior and physiological reactivity were measured. For most emotions, more cultural similarities than differences were found. There were some exceptions: During happiness, fewer HAs than EAs showed non-Duchenne smiles (i.e., "social" smiles), despite similarities in reported emotional experience and physiological reactivity. Within-group differences between "less Hmong" and "more Hmong" HAs were also found. Implications of these findings for our understanding of culture-emotion relations are discussed.

Initiation and supervisory processes in schizophrenia and depression

Clinical studies show that schizophrenic and depressive subjects have problems with daily life activities, and neuropsychological studies tend to explain these problems in terms of a dysexecutive syndrome. Verbal fluency and sentence arrangement are tasks considered to focus on two aspects of the dysexecutive syndrome known as initiation and supervision processes, respectively. In this study, we assessed performance in these two tasks in schizophrenia and depression. Twenty-six schizophrenic subjects (chronic schizophrenia, DSM IV definition) were compared with 26 control subjects balanced for sex, age and educational level, and 16 depressive subjects (major depression episode, DSM IV) were compared with 11 similarly balanced control subjects. Switching and clustering scores were evaluated during a semantic fluency task as two components underlying the initiation and organization processes. Capture errors specific to failure of the supervisory system and differences between the number of correct responses in two conditions (valid/invalid) were evaluated as indexes of the supervision process in a sentence arrangement task. In the semantic fluency task, switching scores were significantly lower in the schizophrenic and depressive subjects than in their respective controls. In the sentence arrangement task, only the schizophrenic subjects made significantly more capture errors than their controls and had significantly fewer correct sequences in invalid conditions than in valid conditions. This study shows a dissociation between supervision and initiation processes in two different psychiatric populations. Initiation is impaired, but supervision is preserved in depression, whereas both initiation and supervision are impaired in schizophrenia.     

Anhedonia and the experience of emotion in individuals with schizophrenia.

Research shows that individuals with schizophrenia report symptoms of anhedonia when assessed by interview or questionnaire. However, when presented with emotional stimuli, they report emotional experiences that are similar to those of control participants. The authors hypothesized that deficits in working memory and episodic memory contribute to such discrepancies. They administered measures of working and episodic memory, self-report anhedonia questionnaires, and several types of emotional stimuli to 49 individuals with schizophrenia and 47 control participants. All participants reported experiencing similar amounts of pleasant-unpleasant emotion (valence) in response to stimuli, but individuals with schizophrenia reported experiencing less arousal for negative stimuli. Individuals with schizophrenia also reported greater social and physical anhedonia on a traditional anhedonia questionnaire. Disturbances in working memory moderated the relationship between physical anhedonia and participants' emotional experience of positive stimuli.

Changes in perceptual asymmetries with clinical improvement of depression and schizophrenia.

16 depressed patients, 16 schizophrenic patients, and 16 normal controls (20–50 yrs old) were given 2 dichotic listening tests and 2 cognitive tests at intervals ranging from patients' initial hospitalization to recovery. Repeated-measures ANOVA revealed that severely depressed Ss failed to obtain normal ear-superiority in either dichotic test; however, normal superiorities emerged with recovery from depression. Schizophrenic Ss initially failed to show normal right-ear superiority on a dichotic-words test but did obtain the expected left-ear advantage on a dichotic-chords test. Following treatment, schizophrenics shifted from a left-ear to a right-ear advantage in dichotic chords and also increased (although not significantly) their right-ear advantage in dichotic words. Both patient groups showed normal word-fluency but impaired spatial ability, which did not improve with recovery. Results suggest that both depression and schizophrenia are associated with a breakdown in the process of interhemispheric inhibition that mediates perceptual asymmetry. In depression, treatment returned Ss' normal patterns of asymmetry, whereas in schizophrenia, treatment created an abnormal pattern of asymmetry that may have reflected the allocation of both verbal and nonverbal material to the left hemisphere.

Emotional experience in everyday life across the adult life span.

Age differences in emotional experience over the adult life span were explored, focusing on the frequency, intensity, complexity, and consistency of emotional experience in everyday life. One hundred eighty-four people, age 18 to 94 years, participated in an experience-sampling procedure in which emotions were recorded across a 1-week period. Age was unrelated to frequency of positive emotional experience. A curvilinear relationship best characterized negative emotional experience. Negative emotions declined in frequency until approximately age 60, at which point the decline ceased. Individual factor analyses computed for each participant revealed that age was associated with more differentiated emotional experience. In addition, periods of highly positive emotional experience were more likely to endure among older people and periods of highly negative emotional experience were less stable. Findings are interpreted within the theoretical framework of socioemotional selectivity theory. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Sex roles and gender differences in the experience of depression.

Studied sex differences and sex role correlates of depressive experiences in 82 female and 39 male college students. Gender differences in depressive experiences were found. These differences were consistent with societal sex role expectations. The level of depression on the Zung Self-Rating Depression Scale was negatively associated with sex role congruence, as assessed by the Sex-Role Stereotype Questionnaire, scored for Competency and Warmth–Expressiveness. Degree of sex role congruence within the male and female samples was also associated with different depressive experiences on the Depressive Experiences Questionnaire. The sex differences and the different intrasex correlations indicated that experiences of depression are associated with different facets of sex role stereotypes.

Dysfunctional attitudes and attribution style in healthy controls and patients with schizophrenia, psychotic depression, and nonpsychotic depression.

Compared the scores of 242 psychiatric inpatients with schizophrenia, psychotic depression, or nonpsychotic depression and 53 healthy controls on the Attribution Style Questionnaire (ASQ) and the Dysfunctional Attitude Scale (DAS). Results provide mixed support for the cognitive and learned helplessness models of depression. Depressed Ss scored significantly higher than healthy controls on the DAS and ASQ, but there were no differences between depressed and schizophrenic Ss.

Emotional self-disclosure and emotional avoidance: Relations with symptoms of depression and anxiety.

Research suggests that individuals with heightened symptoms of mood and anxiety disorders engage in diminished emotional disclosure. On the basis of emotion regulation theories, the authors hypothesized that this symptom–disclosure relationship would be mediated by the avoidance of emotional experience and expression. In Study 1, college students (N = 831) completed measures of depression and anxiety symptoms, measures of tendencies to avoid emotional expression, and measures of tendencies to self-disclose distress. Structural equation modeling revealed that anhedonic depression and anxious arousal were associated with lessened emotional self-disclosure tendencies as mediated by avoidance of emotional expression. In Study 2, participants (N = 153) completed new measures of depression and anxiety symptoms, reflected on the most significant emotional event experienced during the past week, and rated their avoidance of emotion about the event and their self-disclosure of the event. Depression (but not anxiety) symptoms were negatively related to the disclosure of a specific event, but avoidance of emotional experience did not mediate this depression–disclosure relationship. These findings extend emotion dysregulation theory and suggest that depressive symptoms in particular are associated with reduced emotional disclosure.

Therapist experience, general clinical ability, and treatment outcome in schizophrenia.

Knowledge of the effect of therapist training and experience on the outcome of treatment of schizophrenic patients is scanty. The present article presents data systematically collected in the course of a controlled comparison of the effects of 5 different treatment methods in schizophrenia (individual psychotherapy, ataractic drug treatment, individual psychotherapy and drug treatment, ECT, and "milieu" care) involving 228 1st-admission schizophrenics without significant prior treatment and 38 psychiatric residents or recently graduated psychiatrists. Among the 23 outcome variables studied (including the Menninger Health-Sickness Scale, the Camarillo Dynamic Assessment Scale, the MMPI, the Communication subscale of the MACC Behavioral Adjustment Scale, and the Clyde Mood Scale), there was not a single instance in which the effect of therapist experience and general clinical ability was significantly related to outcome. There appeared to be, however, differences among therapists' results that were not related to experience and general clinical ability, particularly in relation to the length of time that they kept their patients in hospital. Drug treatment tended to override but perhaps not entirely eliminate these effects. (36 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Previous personal experience and reactions to depression and physical disability.

Conducted 2 experiments with 121 undergraduates to examine the effects of prior experience with people with disability on interpersonal reactions to depression expressed by a person with a disability. In the 1st study, Ss rejected further involvement with the depressed person and perceived this person to be socially impaired. In the 2nd study, Ss ascribed significantly more negative personal characteristics to the depressed person and evidenced more stereotypic attitudes toward persons with disability than Ss who viewed the nondepressed person. Results provide evidence that prior personal experience with people with disability does not moderate negative reactions to social displays of depressive behavior.

Perceptual accuracy in schizophrenia, depression, and neurosis, and effects of amytal.

"Three perceptual tests were given to four groups of hospitalized patients: chronic schizophrenics, early schizophrenics, depressives, and neurotics. The tests, Hands, Street Gestalt, and Rorschach, were administered first without then with intravenous sodium amytal and amphetamine sulphate. Without drugs, on the Hands test, the groups did not differ in accuracy. On Gestalt Completion, the CS and Dp groups gave fewer correct responses than the ES and Nt groups… . Beck's finding of lowered F + % in schizophrenia was confirmed. With drugs, on the Hands test, all groups were less accurate. On Gestalt Completion, all groups were more accurate and gave fewer rejections and unique responses. There was no change in Rorschach F + %."

Emotional experience improves with age: Evidence based on over 10 years of experience sampling.

Recent evidence suggests that emotional well-being improves from early adulthood to old age. This study used experience-sampling to examine the developmental course of emotional experience in a representative sample of adults spanning early to very late adulthood. Participants (N = 184, Wave 1; N = 191, Wave 2; N = 178, Wave 3) reported their emotional states at five randomly selected times each day for a one week period. Using a measurement burst design, the one-week sampling procedure was repeated five and then ten years later. Cross-sectional and growth curve analyses indicate that aging is associated with more positive overall emotional well-being, with greater emotional stability and with more complexity (as evidenced by greater co-occurrence of positive and negative emotions). These findings remained robust after accounting for other variables that may be related to emotional experience (personality, verbal fluency, physical health, and demographic variables). Finally, emotional experience predicted mortality; controlling for age, sex, and ethnicity, individuals who experienced relatively more positive than negative emotions in everyday life were more likely to have survived over a 13 year period. Findings are discussed in the theoretical context of socioemotional selectivity theory. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
