Maternal Representations of Patients with Schizophrenia as Measured by the Parental Bonding Instrument

Maternal perceptions were assessed, using the Parental Bonding Instrument (PBI) in 19 subjects with schizophrenia, 14 subjects with borderline personality disorder and 15 non-clinical subjects. Subjects with schizophrenia and subjects with borderline personality disorder reported significantly less care and more overprotection than did non-clinical subjects. No significant differences were found in representations by subjects with schizophrenia and subjects with borderline personality disorders. To the extent that the reported negative maternal behaviour gives a true picture of childhood and adolescent experiences, it does not seem to be specific for schizophrenia, but may be one factor in the development of severe mental disorders.

A diffusion model analysis of the effects of aging in the lexical-decision task

The effects of aging on response time (RT) are examined in 2 lexical-decision experiments with young and older subjects (age 60-75). The results show that the older subjects were slower than the young subjects, but more accurate. R. Ratcliff s (1978) diffusion model provided a good account of RTs, their distributions, and response accuracy. The fits show an 80-100-ms slowing of the nondecision components of RT for older subjects relative to young subjects and more conservative decision criterion settings for older subjects than for young subjects. The rates of accumulation of evidence were not significantly different for older compared with young subjects (less than 2% and 5% higher for older subjects relative to young subjects in the 2 experiments).     

Judging health status: effects of perceived prevalence and personal relevance

In this article, we show that people's evaluations of the seriousness of a health disorder are influenced by the perceived prevalence and personal relevance of that disorder. As part of a study ostensibly concerned with college students' health characteristics, 60 undergraduates were "tested" for the presence of a fictitious enzyme deficiency. The subjects discovered either that they had the deficiency (deficiency-present subjects) or that they did not have it (deficiency-absent subjects), and were led to believe either that 1 of the 5 people in the laboratory had the deficiency (low-prevalence subjects) or that 4 of them had it (high-prevalence subjects). As predicted, the low-prevalence subjects evaluated the deficiency as more serious than did the high-prevalence subjects. In addition, consistent with the view that personal relevance affects perceptions of health disorders, the deficiency-present subjects evaluated the deficiency as less serious than did the deficiency-absent subjects. The deficiency-present subjects also derogated the validity of the test ostensibly used to diagnose the deficiency compared with other subjects. Finally, the deficiency-present subjects requested more information about the deficiency than did the deficiency-absent subjects.     

Second year treatment outcome of alcoholics treated by individualized behavior therapy: Results

Second year treatment outcome results are reported for 69 of 70 male alcoholics who, while hospitalized at Patton State Hospital, served as subjects in an experiment evaluating ‘Individualized Behavior Therapy (IBT)’ techniques. Subjects were initially assigned to either a controlled drinking or non-drinking (abstinence) treatment goal. and were then randomly assigned to either an experimental group receiving IBT or a control group receiving conventional state hospital treatment oriented towards abstinence. Previously reported results found that IBT subjects functioned significantly better than control subjects throughout the first year of follow-up. Second year follow-up results found that IBT subjects treated with a controlled drinking goal functioned significantly better than their respective control subjects on a variety of measures, including drinking behavior. Differences between IBT subjects treated with a non-drinking goal and their control subjects did not retain statistical significance during the second year of follow-up. Individual drinking profiles are presented for all subjects. Only subjects treated by IBT with a goal of controlled drinking engaged in a substantial amount of limited, non-problem drinking during the second year interval, and those subjects also had more abstinent days than subjects in any other group. The nature of adequate follow-up procedures and measures is discussed. Implications of these findings for alcoholism treatment are considered.     

Processes of verbal memory failure in Alzheimer-type dementia

Multiple aspects of verbal learning and memory performance in mild as compared to moderate Alzheimer-type dementia (ATD) were studied with the Buschke selective reminding paradigm. Results show that (1) both groups of ATD subjects depend less on long-term memory (LTM) and more on short-term memory (STM) relative to elderly control subjects, (2) mild ATD subjects show less LTM encoding than moderate ATD subjects, (3) moderate ATD subjects retrieve a smaller portion of the items presumed to be encoded into LTM than do mild ATD subjects, and (4) high-imagery words increase LTM encoding and retrieval as compared to low-imagery words for moderate ATD subjects only. These results are explained by the inability of ATD subjects to attend to more than one component of the list-learning task, in conjunction with differences in the deployment of attention between mild and moderate ATD subjects.     

A CROSS-CULTURAL STUDY OF RECOGNITION MEMORY FOR FACES1

The hypothesis that subjects would show superior memory for faces of members of their own ethnic group compared with those of a different ethnic group was tested in a cross-cultural experiment. Thirty two African and 32 European subjects were presented with coloured photographs of ten black Africans and ten white Europeans, with the instruction to try to remember them. Twenty four hours later, the subjects were presented with the same photographs shuffled with an equal number of new photographs of Africans and Europeans, and were asked to identify those they had seen before. The index d' was used as a measure of recognition. As predicted, European subjects were superior at recognising European faces compared with African faces, and African subjects were superior at recognising African faces compared with European faces. Response bias data indicated that European subjects had a differential response bias for the photographs of the two ethnic groups, but African subjects did not differ in their bias towards the two ethnic groups. African subjects did, however, show differential response bias for sex within the European faces. The results were discussed in terms of perceptual discrimination and stereotyping.     

Individualized behavior therapy for alcoholics: a third year independent double-blind follow-up.

An independently conducted double-blind study providing third year follow-up data for 53 of 70 male alcoholics who served as subjects in an experiment evaluating “Individualized Behavior Therapy (IBT)” techniques is reported. In the original study, subjects were initially assigned to either a controlled drinking or non-drinking (abstinence) treatment goal, and were then randomly assigned to either an experimental group receiving IBT or a control group receiving conventional state hospital treatment oriented towards abstinence. Previously reported results showed that IBT subjects functioned significantly better than control subjects throughout the first year of follow-up. Second year follow-up results found that IBT subjects treated with a controlled drinking goal functioned significantly better than their respective control subjects on a variety of measures, including drinking behavior. Differences between IBT subjects treated with a non-drinking goal and their control subjects did not retain statistical significance during the second year of follow-up. The independently determined follow-up data showed that during the third post-treatment year, subjects in the experimental groups generally functioned better than their respective control subjects. Comparison of the controlled drinking experimental group with its control group showed the significantly better functioning of subjects in the experimental condition on a number of drinking and other life functioning measures. Comparison of the non-drinking groups indicated only one possible difference on the drinking related measures involving a trend for subjects in the experimental condition to abstain more than those in the non-drinker control group. On other life functioning measures, however, subjects in the non-drinking experimental condition showed consistent improvement over their respective control subjects. Both of the controlled drinking groups reported more controlled drinking days than the non-drinking groups throughout the third year follow-up period.     

Sensitivity of persons with hearing impairment to visual emotional expression — compensation or deficit?

The research examined whether subjects with hearing impairment would differ from normal hearing subjects in their ability to decode emotions from video stimuli (48 video takes in which two actors portrayed six different emotions). Studies in tactile and visual perception lead one to expect deficits, while there is also some evidence for compensation. Twenty-six subjects with hearing impairment and 26 matched normal hearing subjects participated (average age = 25.5 years; nine female, 17 male subjects in each group). Results indicate that in general subjects with hearing impairment were slightly less successful in decoding emotions from the visual stimuli than the normal hearing subjects. A comparison between highly (loss > 60–90 dBA) and moderately (loss about 30–60 dBA) impaired subjects on the other hand indicated poorer emotion decoding only for the moderately impaired group. Post-hoc analyses indicated that these effects were specific to males. Results are discussed with respect to compensation versus deficit, and with respect to issues of training.     

Response to hyperventilation and inhalation of 5.5% carbon dioxide-enriched air across the DSM-III-R anxiety disorders.

Anxiety disorder patients (n = 198; under criteria of the Diagnostic and Statistical Manual of Mental Disorders; rev. 3rd ed.; American Psychiatric Association, 1987) and nonanxious control subjects (n = 25) underwent challenges of 90 s of voluntary hyperventilation and 15 min of 5.5% carbon dioxide in air. Panic disorder subjects showed a greater subjective response to both challenges than did subjects with other anxiety disorders, who in turn responded more than did control subjects. Furthermore, subjects with panic disorder as an additional diagnosis tended to report more subjective response than did anxiety disorder subjects without panic disorder. The best prechallenge predictor of response to each procedure was a measure of fear of physical symptoms. The findings support previous results that have pointed to a greater fear or anxiety-inducing effect of these challenge procedures in panic disorder patients, as compared with other subjects.     

Modality effects: Do they fall on deaf ears?

The present study tests the assumption of the PAS theory of echoic memory (Greene & Crowder, 1984) that the representation of acoustic features is necessary in producing modality effects. Performance by deaf subjects was compared to hearing subjects on serial and free-recall tasks with vocalizing and non-vocalizing conditions. For the serial tasks, typical modality and acoustic similarity effects were observed with hearing subjects, and no such effects were found with deaf subjects. However, for the free-recall task, modality effects were found for both deaf and hearing subjects. It is unlikely that phonological coding resulting from gestural cues mediates the modality effect, as phonological confusion errors for deaf and hearing subjects did not correlate with the size of this effect.     

The Relationship between Defense Preference and Response to Free Association

Psychoanalytic theories suggest that individuals with obsessive defenses, with hysterical defenses, and borderline psychotic individuals respond differently to free association. An experimental analogue of the psychoanalytic session was used to test these ideas. The subjects were 68 male college students, chosen on the basis of the Rorschach and MMPI. Contrary to predictions, obsessive subjects generally associated more freely and showed more involvement in the sessions than hysterical subjects. As expected, hysterical subjects were more silent and blocked and made fewer self-observations than obsessive subjects. Borderline subjects were judged to have less control over drive than the two defensive types.     

Response Imagery: Aftereffects and Reminiscence

In two experiments, subjects imagined themselves performing a tracking task under a massed practice schedule. After interpolated rest or no rest, subjects actually performed the criterion task. Some subjects' imagery was augmented with sounds that matched the temporal characteristics of the criterion task. These subjects produced greater aftereffects than subjects who imaged without augmentation or subjects provided with imagery augmentation matching a variation of the criterion. Reminiscence (performance gain attributed to interpolated rest) was demonstrated with imagery, except when the accompanying augmentation was faster than the criterion.     

Multiple sessions of systolic blood pressure biofeedback: Its effects on ability to control systolic pressure during training,after training,and its effects on pulse rate

Seventy-one normotensive subjects participated in four training sessions in which they were either (a) instructed to increase their blood pressure, (b) instructed to decrease their blood pressure, or (c) not instructed to change their blood pressure. The subjects either (a) were provided with biofeedback concerning systolic blood pressure or (b) were not provided with biofeedback concerning systolic blood pressure. After the last training session, subjects participated in a transfer session in which they were again instructed concerning changes in pressure but were not provided with biofeedback. Analyses conducted on data from the training and transfer sessions indicated that subjects who were instructed to increase pressure and given biofeedback to aid them showed higher pressure than subjects in other conditions and that there were no differences among those other conditions; that is, biofeedback was effective for teaching subjects to increase pressure but was not effective for teaching subjects to decrease pressure. Additional training sessions did not add to the effect achieved in the first training session. During training sessions, subjects who were instructed to increase pressure showed higher heart rates than subjects in other conditions. The results raise questions concerning the interpretation of earlier experiments that did not include no-treatment, instructions-only, and attention control conditions.     

Barrier and penetration scores in relation to some objective and subjective somesthetic measures

Barrier and Penetration scores in relation to some variables, such as muscular tone at rest, sensitivity to tickle, and body perception were studied in a group of 35 female subjects. While no correlations appear within the whole group of subjects between Barrier scores and the other variables, on the left side of the body. Dividing subjects on the basis of Barrier scores, three groups with different characteristics appear: 12 subjects with high Barrier scores show an inverse relation of Barrier scores with sensitivity to tickle on the right side of the body; 12 subjects with middle Barrier scores show a direct relation of Barrier scores with muscular tone and an inverse one with both latency of tickle on the right half of the body and body perception; 11 subjects with low Barrier scores show an inverse relation of Barrier scores with durations of tickle on both sides of the body.     

Differences in negative life events between patients with anxiety disorders,depression and hypochondriasis

This study investigated whether some categories of adverse life events are differentially associated with specific types of emotional disorders. A life self-report measure of major life events was completed by 42 subjects with diagnoses of anxiety disorders, 46 subjects with major depression, 26 subjects with hypochondriasis and 73 nonclinical subjects (controls). As predicted, the onset of anxiety disorders, depression, and hypochondriasis appears to be differentially related with life stress of ‘threat’, ‘loss’, and ‘health’, respectively, previously experienced by the clinical subjects. Also, there were significant differences between clinical and nonclinical subjects on both perceived life stress and number of life events reported. Findings suggest a differential implication of psychosocial stress categories in particular emotional disorders (i.e., anxiety, depressive and hypochondriacal disorders). These results expand previous findings that have demonstrated an association between negative life events and psychopathology.     

Superior haptic perceptual selectivity in late-blind and very-low-vision subjects

Blindfolded sighted, congenitally blind, late-blind, and very-low-vision subjects were tested on a tangible version of the embedded-figures test. The results of ANOVAs on accuracy measures yielded superior performance by the very-low-vision and late-blind subjects compared with the blindfolded sighted and congenitally blind participants. Accuracy of the congenitally blind subjects was similar to that of the blindfolded sighted participants. However, all groups of blind subjects were significantly faster than the blindfolded sighted subjects. It is suggested that experience with pictures combined with haptic skill aid perceptual selectivity in touch.     

Eye-Hand Coordination in Aging and in Parkinson’s Disease

Aiming movements to defined target positions were performed as fast and as accurately as possible by younger and older subjects and by patients in the early stages of Parkinson's disease (PD). Movement time and accuracy were tested in two conditions: with and without a centre cue. Older subjects exhibited slower movement time relative to the younger subjects only when the centre cue was present suggesting inefficient feedback processing. The performance of patients with PD was found to be as precise as that of older subjects. The movements of PD subjects, however, were slower in both conditions. Finally, the performance of subjects improved over trials. The data suggest that there is no difference in the nature of the control processes used by older and early-stage PD subjects, but that there is a reduction in the speed of these processes in PD.     

Attribution and aggression: The misattribution of anger

An experiment was designed to test the effect of misattribution of anger on subsequent aggression. Subjects were induced to take a placebo with half of the subjects led to expect arousal symptoms and the other half led to expect relaxation. Crosscutting the pill manipulation, half of the subjects were provoked by a confederate and half were not. All subjects were then given an opportunity to aggress against the confederate. As predicted, relaxation pill-provoked subjects were significantly more aggressive than subjects in the other conditions (p < .025), with arousal pill-provoked subjects no more aggressive than no provocation controls.
