Dream content of schizophrenic, nonschizophrenic mentally ill, and community control adolescents

This study compared the manifest dream content of 20 schizophrenic adolescent inpatients whose medications were stable for at least four weeks, 21 adolescent inpatients with other mental disorders (nonschizophrenic group) matched for age and gender, and 31 matched community controls. All participants were administered the standardized Formal Dream Content Rating Scale (FDCRS), which evaluates dream-related anxiety, cognitive disturbance, implausibility, involvement, primitivity, and recall, as well as two additional scales measuring emotional expression and duration of dream report. The Positive and Negative Symptoms Scale (PANSS) was administered to the two inpatient groups. The community controls demonstrated more involvement and emotional expression than the schizophrenic patients; furthermore, they demonstrated more implausibility and had a greater duration of dream report compared with the nonschizophrenic group. In the schizophrenic patients only, elevated scores on the negative subscale of the PANSS were significantly correlated with lower scores on involvement, emotional expression, and dream recall. No relationship was found between the positive subscale of the PANSS and any of the FDCRS subscales. These results suggest that psychopathology per se, rather than the specific psychiatric disturbance, may be associated with impoverishment of dream content, and that negative, rather than positive, schizophrenic symptomatology may be influential in the dream content of schizophrenic youngsters.     

A CLASSIFICATION SCHEME OF SOCIAL CONDITIONS OF REINFORCEMENT WITHIN GROUP OPERANT SYSTEMS1

Many different reinforcement contingencies are found in group operant systems, such as token economies and point systems. Some systems use group contingencies in which the reinforcement of any one participant may depend on the behavior of some other group member. Other programs are individual, in that participants earn reinforcers dependent only on their own behavior. The various possible arrangements of people and their response requirements are labelled “social conditions of reinforcement” in this paper. Previous attempts at classification have failed to categorize the variety of social conditions of reinforcement. In addition, some conditions that may produce behaviorally different effects have not been separated. The present paper classifies the social conditions of reinforcement found in applied programs in a three-dimensional scheme. The efficacy of the three major dimensions—reinforcing agent, recipient response requirement, and group response requirement—is supported by clinical and research data. The reinforcing agent dimension refers to the person(s) who dispenses reinforcers to group members. This major dimension is further subdivided: one or several agents may be either designated or nondesignated. Recipients are the group members who receive reinforcement. This dimension is also subdivided: one or several recipients in a social condition of reinforcement may obtain reinforcers either contingently or noncontingently. The group response requirement is a criterion that must be satisfied before any group participant is eligible for reinforcement. Some systems have no group requirement, and others have a group requirement that must be met by some designated or nondesignated participant(s). Supportive references and examples are given in the explanation of each dimension and subdimension. The behavioral impact of the various categories is emphasized. For all major dimensions, applied implications and research suggestions are discussed. Concluding remarks center on the utility of the present scheme, the classification of operant procedures other than positive reinforcement, and both theoretical and applied issues requiring further study (e.g., the long-term effects of participation in group contingencies).     

The analysis of group contingency data

The data analyses utilized in group contingency projects are reviewed. Previous studies are cited to emphasize advantages of nonconsolidated ("individual") over consolidated analyses. Several procedures are described that enable applied researchers to incorporate nonconsolidated data analyses in group contingency studies.     

Differential effects of visual-spatial attention on response latency and temporal-order judgment

Summary Theorists from both classical structuralism and modern attention research have claimed that attention to a sensory stimulus enhances processing speed. However, they have used different operations to measure this effect, viz., temporal-order judgment (TOJ) and reaction-time (RT) measurement. We report two experiments that compared the effect of a spatial cue on RT and TOJ. Experiment 1 demonstrated that a nonmasked, peripheral cue (the brief brightening of a box) affected both RT and TOJ. However, the former effect was significantly larger than the latter. A masked cue had a smaller, but reliable, effect on TOJ. In Experiment 2, the effects of a masked cue on RT and TOJ were compared under identical stimulus conditions. While the cue had a strong effect on RT, it left TOJ unaffected. These results suggest that a spatial cue may have dissociable effects on response processes and the processes that lead to a conscious percept. Implications for the concept of direct parameter specification and for theories of visual attention are discussed.     

The role of somatosensory stimulation in social phobia—An analysis of hand coordination in patients and therapeutic dyads during psychodynamic psychotherapy

In the psychotherapeutic treatment of social phobia, the hand movement behaviour exhibited during the interaction provides information about the success of the therapy. In particular, the degree of mutual somatosensory stimulation of the hands (hands moving on each other, as a unit, apart) appears to be relevant regarding the patient's mental state. To test this hypothesis, the present study investigates hand coordination in the course of psychotherapy in patients with and without symptom improvement and in the corresponding therapeutic dyads. Forty-two videos of patient–therapist dyads consisting of 21 patients (n = 11 non-improved; n = 10 improved; according to Liebowitz Social Anxiety Scale self-assessment) from the Social Phobia Research Network project were investigated in early psychotherapy sessions and in pre-last sessions. Hand movements of four randomised video sequences per dyad were analysed with NEUROGES^®-ELAN. Patients with non-improved symptoms displayed shorter act apart coordination and more act on each other coordination than patients with improved symptoms. Patients displayed more act apart and act on each other and less act as a unit coordination than therapists. In therapeutic dyads, act on each other coordination in early sessions, as well as short act apart coordination, was significantly related to non-improvement. Patients with non-improved symptoms are characterised by more hand coordination associated with a high degree of somatosensory stimulation serving self-regulation (act on each other), as well as short complex gestural expressions (act apart). Thus, hand coordination constitutes a progression and outcome parameter informing on somatosensory stimulation.     

The reliability and validity of the psychopathy checklist: youth version (PCL:YV) in nonincarcerated adolescent males

Current knowledge about the validity of the psychopathy syndrome in youth is limited largely to studies relying on parent-teacher rating scales or slight modifications of adult measures. Recently, the Psychopathy Checklist: Youth Version (PCL:YV) was designed for use with adolescents. However, most studies that have used this measure examined incarcerated males and addressed only validity criteria related to antisocial behavior. We investigated the generality and construct validity of the psychopathy syndrome in an adolescent sample by assessing 115 adolescent males on probation with the PCL:YV. Reliability of measurement was high. PCL:YV ratings predicted not only antisocial behaviour but also other indices of childhood psychopathology, interpersonal behaviors associated with adult psychopathy, and a lack of attachment to parents. These findings suggest that the PCL:YV identifies a syndrome in adolescence consistent with theory and research on adult males.     

Screening for adolescent psychopathy among at-risk youth: initial validation of the Survey of Attitudes and Life Experiences

Psychopathic youth pose special challenges to clinicians in providing effective treatment and safe management. Because comprehensive assessments of psychopathy are time intensive and require specialized training, programmatic research is needed to develop time-efficient and useful screens that eliminate from further consideration acting-out adolescents who are unlikely to be psychopathic. The clinical utility of the Survey of Attitudes and Life Erperiences as a psychopathy screen was investigated by combining three samples of adolescent offenders (total N = 223). Its primary purpose was the identification of nonpsychopaths who were distinguished from adolescents in either the mixed or psychopathic ranges. A Psychopathy Screen (PS) Scale was developed with 24-item (PS-24) and 11-item (PS-11) versions. Both appeared moderately effective in excluding nonpsychopaths from further evaluation. Preliminary data on response styles suggest that these scales are not susceptible to social desirability.     

The Situational Context <Emphasis Type="Italic">on the Nature of Political Philosophy</Emphasis>

Rationalism in political philosophy is the view that politics should be governed by moral principles and that those principles can and should be justified independently of the situations and circumstances that make up political reality. This traditional view of political philosophy implies that the meaning of right political action is determined by moral principles the rational authority of which derives from abstract philosophical reasoning, not from the situations and circumstances that are the substance of political reality. In this essay I argue that rationalist moralities must presuppose the understanding of particular situations and circumstances for their meaningful and correct interpretation. This means, I argue, that the rightness of political judgement and action is immanent in particular situations, not in abstract moralities. And this, I argue, suggests a shift from the traditional view of political society as the embodiment of abstract principles, towards a view of political society as the embodiment of the activity of situational judgement. A society worth hoping for, then, is one in which we can live in the light of our understanding of the situations and circumstances that are the substance of everyday life, rather than in the shadow of abstract moralities. Such a society would be sensitive to the particularities and complexities of political reality, but at the same time it does not succumb to moral relativism and skepticism.     

Interference and negative priming effects in adolescents with attention deficit hyperactivity disorder

Three visual selective attention tasks were used to measure potential differences in susceptibility to interference and inhibitory cognitive control processes in 16 adolescents diagnosed with attention deficit hyperactivity disorder (ADHD) and 45 similar-aged controls. Susceptibility to interference was assessed using the Stroop color and word naming test. Efficiency of distractor inhibition was assessed in two conceptual negative priming tasks. The majority of studies in this area indicate that people with ADHD demonstrate higher levels of interference and lower negative priming effects in comparison with age-matched peers. However, we found that although the ADHD group was consistently slower to name target stimuli than the control group, there were no differences in interference or negative priming between the two groups.
