Neuropsychological performance and positive and negative symptoms in schizophrenia.

Examined cognitive functions in 11 positive-symptom (mean age 36 yrs), 10 negative-symptom (mean age 33.8 yrs), and 23 mixed-symptom (mean age 31.4 yrs) schizophrenics; 15 bipolar patients (mean age 34.7 yrs); and 12 normal controls (mean age 34.8 yrs) to explore the relation between symptoms and performance. Ss were administered a neuropsychological test battery including the Purdue Pegboard, the Revised Visual Retention Test, and the Block Design subtest of the Wechsler Adult Intelligence Scale—Revised (WAIS—R). Group comparisons revealed generalized deficits in schizophrenics. Positive-symptom schizophrenics scored below normal Ss and negative-symptom Ss on 2 measures tapping verbal memory. Multiple regression analyses revealed that negative symptom ratings were inversely associated with performance on visual-motor tasks, whereas positive symptoms were inversely associated with verbal memory performance. Findings are not consistent with the notion that cognitive deficits are uniquely associated with negative symptoms. Instead, results suggest that there may be specific cognitive correlates of both the positive and negative symptom dimensions.

Speed in test performance in depressed patients.

Compared the performance of 2 groups of nonschizophrenic, nonorganic, psychiatric patients—25 depressed (mean age 41.4 yrs) and 25 nondepressed (mean age 37.8 yrs) Ss—on several tests, including the Quick Test, the WAIS, and 10 speed tests and measures of ambiguous figure reversal rates. The 2 groups of Ss were matched for general psychopathology, sex, age, and education. No difference in the performance on power-cognitive (i.e., intelligence) tests was found. Depressed patients performed more slowly on psychomotor speed tests, confirming an earlier study comparing depressed patients and normal controls. Findings generally confirm those of the 1st author et al (1972) and those of several earlier studies summarized by W. R. Miller (see record 1975-20082-001).

Hyperactive and hypoxic children: Signal detection, sustained attention, and behavior.

Two parameters from signal detection theory—perceptual sensitivity and decision criterion cutoff scores—were used in the analysis of vigilance performance of 30 hyperactive (mean age 8.5 yrs), 30 hypoxic (mean age 9 yrs), and 47 normal (mean age 8.8 yrs) children. Signal detection analyses of 3 Continuous Performance Test conditions indicated that with increasing age, Ss obtained significantly more hits, fewer false alarms, higher perceptual sensitivity, and responded with greater caution. Overall deficits in signal discrimination (perceptual sensitivity level) were obtained for both the hyperactive and hypoxic Ss when compared to normal age-mates. Whereas the hypoxic Ss demonstrated additional decrements in sustaining attention (sensitivity decrement over time), the hyperactive Ss were impaired by low-response caution, reflecting difficulty inhibiting impulsive responses. Possible differences in hyperactive sample characteristics across studies and time-related recovery factors following hypoxia are discussed.

Neuropsychological parameters of carotid endarterectomy: A two-year prospective analysis.

To investigate the long-term effects of carotid endarterectomy (CE), 3 groups were studied: (a) 36 patients (mean age 61.1 yrs) receiving CE, (b) 17 patients (mean age 57.9 yrs) with carotid artery disease receiving medical management, and (c) general surgical controls (mean age 55.3 yrs). The Wechsler Adult Intelligence Scale, the Wechsler Memory Scale, and the Halstead-Reitan Neuropsychological Test Battery were administered prior to surgery and at 6 mo and 2 yrs after surgery. Two-way analyses of variance (ANOVA) revealed a significant main effect for trials on a majority of the neuropsychological measures, including the Average Impairment Rating. However, on baseline and on both follow-up evaluations, the CE Ss did not differ significantly from the carotid disease patients who received medical management. Findings fail to support the usefulness of CE in improving mentation or the quality of life in carotid disease patients. (28 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Unilateral lesions and the Wechsler Adult Intelligence Scale—Revised: No sex differences.

Tested sex differences previously reported in WAIS—R scores (Verbal IQ vs Performance IQ discrepancies) in male patients with unilateral lesions by administering the WAIS—R to 31 Ss (16 males [mean age 42.6 yrs] and 15 females [mean age 38.4 yrs]) with right-hemisphere lesions and to 32 Ss (17 males [mean age 32 yrs] and 15 females [mean age 40.7 yrs]) with left hemisphere lesions. Results show that both males and females had expected discrepancies between Verbal IQ and Performance IQ. (14 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memory complaint and memory performance in the depressed elderly.

Compared depressed and nondepressed elderly Ss recruited in the context of a large epidemiological study of health on measures of self-reported memory disturbance and an objective index of memory performance (free recall). Three groups were studied: (a) 26 Ss (mean age 71.56 yrs) meeting Research Diagnostic Criteria (RDC) for major depression, (b) 25 Ss (mean age 72.16 yrs) with high levels of self-reported depressive symptoms who did not meet RDC for major depression, and (c) 26 Ss (mean age 71.81 yrs) with low levels of self-reported depressive symptoms. Ss with high depression symptom levels reported significantly higher levels of memory complaint than did Ss with low symptom levels, but there were no differences in self-reported memory disturbance as a function of depression diagnosis. There were no significant differences between groups on the free-recall measure, either as a function of symptom level or diagnosis. It is argued that symptom severity rather than diagnosis of depression is important in determining impairment in depressed elderly people.

Representational boundaries in role portrayals among paranoid and nonparanoid schizophrenic patients.

Studied the boundary properties of self and other representations in 31 normal Ss (mean age 18.8 yrs) and in 18 paranoid (mean age 21.2 yrs), 14 intermediate (mean age 21.9 yrs), and 16 nonparanoid (mean age 22.1 yrs) inpatient schizophrenics, using a dramatic role-playing technique. Role test and Rorschach responses were scored for presence of fluid and rigid boundaries between representations of human characters. Paranoid schizophrenics evidenced higher levels of rigid boundaries, nonparanoid schizophrenics had higher levels of fluid boundaries, and normal Ss showed fewer fluid or rigid boundaries. Rorschach and role test measures of boundary disruption were significantly correlated with each other and with other measures of psychopathology. Findings suggest that the relative balance between fluid and rigid representational boundaries is an effective discriminator of paranoid and nonparanoid subtypes and that the presence of either type of boundary imagery discriminates schizophrenics from normal Ss.

Memory and metamemory: A study of the feeling-of-knowing phenomenon in amnesic patients.

Tested accuracy of the feeling of knowing in 2 experiments, using 8 patients with Korsakoff's syndrome (mean age 54 yrs), 8 electroconvulsive shock therapy (ECT) patients (mean age 46.5 yrs), 4 Ss (mean age 47 yrs) with other causes of amnesia, 2 alcoholic control groups (7 Ss with a mean age of 47.6 yrs and 19 Ss with a mean age of 48.5 yrs), and 18 healthy controls (mean age 49 yrs). In Exp I, feeling-of-knowing accuracy for the answers to general information questions that could not be recalled was tested. Ss were asked to rank nonrecalled questions in terms of how likely they thought they would be to recognize the answers and were then given a recognition test for these items. Only Korsakoff's syndrome Ss were impaired in making feeling-of-knowing predictions. The other amnesic Ss were as accurate as control Ss in their feeling-of-knowing predictions. In Exp II, these findings were replicated in a sentence memory paradigm that tested newly learned information. Results show that impaired metamemory is not an obligatory feature of amnesia, because amnesia can occur without detectable metamemory deficits. The impaired metamemory exhibited by patients with Korsakoff's syndrome reflects a cognitive impairment that is not typically observed in other forms of amnesia.

Neuroticism and extraversion in Turner's Syndrome.

Administered the Maudsley Personality Inventory to 5 groups of female Ss: (a) 13 Turner Syndrome Ss (mean age 19 yrs 2 mo) with karyotype 45X, (b) 18 Turner Syndrome (TS) Ss (mean age 26 yrs 11 mo) with other types of sex chromosomal abnormalities, (c) 16 sisters of Ss (mean age 24 yrs 2 mo), (d) 9 Ss with growth retardation and primary amenorrhea (mean age 22 yrs 4 mo), and (e) 19 nurses (mean age 22 yrs 8 mo). The results are compared to English and American normative values. The total group of TS Ss obtained a low Neuroticism (N) score compared to the control groups. When the total group was divided on the basis of their karyotypes, the low N score could be referred solely to Ss with karyotype 45X, who scored significantly lower than any other group tested so far with the MPI. TS Ss with chromosomal abnormalities other than 45X scored within normal limits. No variables other than karyotype 45X were related to an extremely low N score. It is concluded that exceptional emotional stability, as reflected in a very low N score on the MPI, is concomitant with the total absence of one sex chromosome, which is probably due to a developmental abnormality of the CNS.

Rejection and depression: Prospective and contemporaneous analyses.

Explored the relationship of parental rejection during childhood and manifestations of depression both then and in young adulthood in 3 studies. In Study 1, 427 Ss were seen in 2 waves at the ages of 8 and 19 yrs. In the 1st wave, the parents of these Ss were also interviewed with a childrearing questionnaire that included a measure of rejection. In the 2nd wave, the Ss, then 19 yrs old, were administered the MMPI—D subscale. In the 2nd study, the contemporaneous relationship between maternal rejection and childhood depression was investigated. The identical measure of rejection used in the prospective study was administered to 245 mothers, and 4 measures of depression—peer ratings, self-ratings, teacher's ratings, and mother's ratings—were obtained for their children (mean age 10.11 yrs). The 3rd study, conducted with 508 mothers and their children (mean age 9.78 yrs) replicated the significant findings of the contemporaneous study. Findings support the hypothesis that deprivation in the generic sense ranging from the death of 1 or both parents to rejection or even parental disharmony is an etiological factor in adult depression.

Children's recognition of rights violations in counseling.

Evaluated the capacity of children and adolescents to comprehend and protect their rights in a mental health setting in 60 male Ss. 20 Ss at each of 3 age levels (8.2–9.7 yrs, 15.2–16.0 yrs, and 20.4–23.1 yrs) were explained 6 rights—refusal of treatment, knowing the reason for refusal, withholding information from counselors, refusal to allow videotaping of a treatment session, confidentiality, and the right of access to records—and then asked to view videotapes in which these rights were violated. Results show that, for 9-yr-old Ss, the experimental effect of providing information about rights was minimal; both experimental Ss and noninformed controls demonstrated low scores on measures of recognition of rights violation and protection of rights. At ages 15 and 21, experimental Ss demonstrated significantly higher scores on both measures than did control Ss. There was no significant difference in the experimental effect between the 15- and 21-yr-old Ss, which suggests that by age 15, the average adolescent is fully capable of comprehending and exercising his or her rights. Guidelines are proposed regarding the provision of information about rights to minors who receive mental health services. (25 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Some preliminary data on the psychological characteristics of Vietnam veterans with posttraumatic stress disorders.

There appears to be a high incidence of posttraumatic stress disorders (PTSDs) among Vietnam combat veterans; yet, there is little information available on the utility of traditional psychological inventories for assessment of this disorder. The present study examined whether responses on a variety of standardized psychological inventories (the MMPI, Self-Rating Depression Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, and Fear Survey Schedule–II) would distinguish 3 carefully matched groups of Vietnam veterans: (a) 12 Ss (mean age 34 yrs) with an exclusive diagnosis of PTSD, (b) 12 Ss (mean age 35 yrs) with other nonpsychotic psychological diagnoses, and (c) 12 Ss (mean age 34 yrs) with combat experience who are currently well-adjusted. Univariate and multivariate statistical analyses indicated that the assessment battery was able to discriminate with good success Vietnam combat veterans with PTSD from relevant comparison groups.

Factorial validity of Stephen's Social Behavior Assessment.

Conducted exploratory factor and item analyses of the Social Behavior Assessment (SBA), using teacher ratings of 301 elementary school pupils from regular classes (mean age 9.4 yrs), 39 learning disabled students (mean age 9.1 yrs), and 62 emotionally disturbed children (mean age 10.1 yrs). It was found that a 5-factor oblique solution was the most reasonable. Factors obtained from item analysis explained more of the variance than factors based on subcategory scores. A shorter revised instrument is proposed that consists of 71 items based on 4 underlying factors—Social Participation/Conversation, Academic Responsibility, Self-Control, and Consideration for Others. This revised SBA discriminated between Ss in regular classes and those enrolled in special education programs. Emotionally disturbed Ss had the most deviant scores on each of the 4 factors.

The Seashore Tonal Memory Test as a neuropsychological measure.

Evaluated the sensitivity of the Seashore Tonal Memory Test to impaired brain function and compared it with that of the Halstead-Reitan Neuropsychological Test Battery and the Trail Making Test. Neurologic Ss consisted of 102 individuals (mean age 26.45 yrs) with histories of head trauma or epilepsy, and control Ss consisted of 68 individuals (mean age 27.22 yrs) without histories of neurological problems. In general, the Tonal Memory Test differentiated the normal and neurologic Ss on either an S-by-S or group-by-group basis as well as did the other neuropsychological measures, and without excessive overlap with them.

Emotional, behavioral, and physiological effects of chronic stress at Three Mile Island.

38 Three Mile Island (TMI) residents (mean age 33.3 yrs) were compared with 32 people (mean age 35.8 yrs) living near an undamaged nuclear power plant, 24 people (mean age 34.1 yrs) living near a traditional coal-fired power plant, and 27 people (mean age 30.9 yrs) living in an area more than 20 miles from any power plant. A number of self-report measures of psychological stress were evaluated by administering the Symptom Checklist-90 and the Beck Depression Inventory more than 1 yr after the nuclear accident. Two behavioral measures of stress were obtained: performances on a proofreading task and an embedded-figures task. Urinary catecholamine levels were assayed to examine chronic stress-related sympathetic arousal. Results indicate that Ss in the TMI area exhibited more symptoms of stress more than 1 yr after the nuclear accident than did Ss living under different circumstances. Although the intensity of these problems appears to be subclinical, the persistence of stress may be cause for some concern.

Geriatric patients who improve in token economy and general milieu treatment programs: A multivariate analysis.

Assigned 80 chronic geriatric mental hospital patients, mean age 68.8 yrs, to token economy and general milieu programs. In each program, staff received the same amount of training, and the physical environments were identical. All Ss were rated with the Psychotic Inpatient Profile and the Vigor Intactness Relationship Orientation. Results show significant decreases over 6 mo on both wards in frequency of bizarre and unusual behaviors. Incontinence decreased immediately after transfer to the treatment wards, and there were changes over 6 mo in the amount of staff care given to Ss. Multiple discriminant analyses indicated that in each ward different constellations of pretreatment characteristics discriminated between Ss who improved and those who did not improve in the frequency of bizarre and unusual behaviors. In the token economy, improved Ss were characterized as less "institutionalized," in better physical condition, and actively exhibiting their troubles. In the general milieu, improved Ss were discriminated by less responsiveness to an interviewer. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gender dysphoria, gender reorientation, and the clinical management of transsexualism.

Conducted 2 studies of gender dysphoria and postoperative adjustment by transsexuals. Study 1 examined the relation of gender reorientation (approximation of the status of the opposite biological sex) to psychological adjustment in gender dysphorics. Three S groups (75 heterosexual males, mean age 36.7 yrs; 85 homosexual males, mean age 29.8 yrs; and 103 biological females, mean age 27.4 yrs) were studied in multiple regression analyses, with psychological symptoms as criteria and measures of 3 roughly sequential components of gender reorientation (role changes, document changes, and physical changes), age, and education as predictors. Psychological complaints correlated negatively with the earliest phase of reorientation for females and with the later phases for males. Age and education bore little relation to current symptoms. Results suggest that psychological improvement accompanies gender reorientation in both male and female gender dysphorics; the greatest degree of improvement is seen earlier in the process for females. Ss in Study 2 were postoperative transsexuals (32 homosexual males, mean age 33.2 yrs; 9 heterosexual males, mean age 47.7 yrs; and 38 biological females, mean age 32.6 yrs) at least 1 yr after surgery. Follow-up rate was 77.5% for all Ss meeting the 1-yr criterion. Satisfaction with surgery was high, and psychosocial adjustment was acceptable for the majority. Results of both studies support the rationale for clinical intervention in aid of gender reorientation in selected cases. (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychotherapist heal thyself: II. The self-initiated and therapy-facilitated change of psychological distress.

Attempted to identify mechanisms of successful coping and to explicate differences between self-change (improvement without therapy) and therapy change (improvement with therapy) among 3 samples of women: 83 psychologists (mean age 46.9 yrs), 108 mental health counselors (mean age 39.1 yrs), and 94 laypersons (aged 18–77 yrs). Ss completed a packet consisting of a demographics and history questionnaire, a typology of psychic distress, a processes of change scale, and a ways of coping checklist. All Ss were within the high range for a distress episode in the previous 3 yrs and had made a concerted effort to change their distress without or before seeking professional treatment. Compared with self-changers, therapy-changers were more likely to have undergone psychotherapy in the past, experienced distress for longer periods of time, and rated their self-change as less successful. In the layperson sample, but not the psychologist or counselor samples, therapy-changers reported more frequent use of several coping processes than self-changers, perhaps attributable to the professional intervention.

The feeling of knowing experience in educable retarded children.

Required 50 educable retarded children to predict their recognition accuracy when recall failed. Ss were divided into 3 ability levels: (a) old Ss (mean CA 13.25 yrs, mean MA 10.5 yrs), (b) medium Ss (mean CA 11.25 yrs, mean MA 8.75 yrs), and (c) young Ss (mean CA 9 yrs 5 mo, mean MA 6 yrs 9 mo). Results indicate that old and medium Ss could reliably predict their recognition accuracy, suggesting sensitivity to their own feeling of knowing experience, but that the young Ss showed no evidence of this sensitivity. Even though the young Ss had difficulty predicting their recognition accuracy in advance they were able to estimate the success or failure of their responses after they had occurred. Results are discussed in terms of the complexity of the metamemory judgment required, and the advisability of evaluating metamemorial knowledge across several situations is emphasized.

The relation between meaning in life and the occurrence of drug abuse: A retrospective study.

Conducted an epidemiological, retrospective study to compare personal meaning in life (e.g., V. Frankl, 1959) between a group of 49 individuals (mean age 29.4 yrs) receiving inpatient treatment for drug abuse and a group of 49 matched, non-drug-abusing controls (mean age 29.1 yrs). All Ss completed the Purpose in Life Test and Life Attitude Profile—Revised. With both instruments, the inpatient drug-abusing Ss were found to have significantly lower levels of meaning in life. Results suggest that drug treatment and primary prevention programs should consider giving some attention toward life meaning issues in their intervention strategies.
