Schizotypy and verbal memory in the adolescent general population

The following study examines the relationship between verbal memory deficits and schizotypal traits measured psychometrically from a non- clinical adolescent population. In this transversal analytical study participated 139 subjects. They were secondary school students, with ages ranging from 13 to 16 years old (mean= 14, 35; Sta.Dev.= 0, 548). After administrating the scales O-LIFE (psychometrical schizotypy), CVLT (verbal memory), and Letters and Numbers subtest of WAIS-III (working memory), data was analyzed utilizing Pearson correlations and mean comparison test. Results showed lack of relations between schizotypy measures and working memory. Nonetheless, some of the O-LIFE dimensions correlated with verbal memory. These findings support partly the literature reviewed. Yet, more work focused on schizotypy and cognitive deficits as risk factors are suggested.     

Equivalence classes formation applied to learning musical notes

Three experiments involving training and application of equivalence classes were carried out. In the first of them, with 6-6 years old children, and applying the equivalence classes logic to musical symbols and sounds learning, the necessary relations to build three equivalence classes (do, mi, sol) of five members each were acquired. In second and third experiments, five and seven equivalence classes (musical notes) of five member each were obtained. Six and a half years old children and one 17 years old Down syndrome diagnosed child took part in them, respectively. Results highlight the theoretical meaning of equivalence classes as explanation of human symbolic behavior, as the educational incomes of improving learning of basic elements in artistic skills.     

Psychological processes and family variables as prosocial behavior predictors in a sample of Spanish adolescents

A review of personal and family variables that regulate prosocial behavior is based on a sample of 1,433 Spanish adolescents (ages 9 to 13; 743 boys and 690 girls) who were assessed on the Prosocial Reasoning Objective Measure, the Physical and Verbal Aggression Scale, the Emotional Instability Scale, the State-Trait Anger Inventory, the Child's Report of Parental Behavior Inventory, the Prosocial Behavior Scale, and the Index of Empathy for Children and Adolescents. Discriminant analyses showed that empathy, self-control in anger-provoking situations, and affection in family relationships are the best predictors of prosocial behavior.     

Autobiographical memory, autonoetic consciousness, and self-perspective in aging

In this study, the authors examined the effects of aging on autobiographical memory in 180 participants by means of a new method designed to assess across 5 lifetime periods the nature of memories-that is, specificity and spontaneity--and the phenomenal experience of remembering--that is, self-perspective and autonoetic consciousness--via the field/observer and remember/know paradigms respectively. Age-related differences were found for the specificity and spontaneity of memories and the phenomenal experience of remembering. There was an increase in observer and know responses with age, but a decrease in field and remember responses and in the ability to justify them by recalling sensory-perceptive, affective, or spatiotemporal specific details. This pattern confirms the existence of a semantic-episodic dissociation in autobiographical memory in aging. Moreover, the data support the view that older participants can subjectively "travel back in time" to relive personal events in the most distant past better than those in the recent past.     

Interpersonal dynamics in sport: The role of artificial neural networks and 3-D analysis

In previous attempts to identify dynamical systems properties in patterns of play in team sports, only 2-D analysis methods have been used, implying that the plane of motion must be preselected and that movements out of the chosen plane are ignored. In the present study, we examined the usefulness of 3-D methods of analysis for establishing the presence of dynamical systems properties, such as phase transitions and symmetry-breaking processes in the team sport of rugby. Artificial neural networks (ANN s) were employed to reconstruct the 3-D performance space in a typical one-versus-one subphase of rugby. Results confirm that ANs are reliable tools for reconstructing a 3-D performance space and may be instrumental in identifying pattern formation in team sports generally.     

Inattentional blindness for negative relationships in human causal learning

The present study focuses on the effect of selective attention on causal learning. Three effects of the level of attention to predictive symptoms in positive and negative contingency learning tasks are reported. First, participants accurately detected a positive relationship between an incidental cue and a contingent outcome, although judgements were slightly lower than those for the attended cue. Second, participants were unable to detect negative relationships between incidental cues and outcomes, which suggests a major role of selective attention in this type of learning. Third, participants retrieved the frequency of each trial type more accurately in the attended conditions than in the incidental conditions. These findings show how attention guides and constrains human causal learning and reveal an inattentional blindness effect for negative contingency learning.     

Long-term outcome after discontinuation of benzodiazepines for insomnia: a survival analysis of relapse

Discontinuation of benzodiazepine (BZD) treatment for insomnia can be a difficult task. Cognitive-behavior therapy (CBT) for insomnia, combined with a supervised medication taper, can facilitate withdrawal but there is limited evidence on long-term outcome after discontinuation. The objective of this study was to examine medication-free survival time and predictors of relapse (i.e., resumed BZD hypnotics) over a 2-year period in 47 older adults (mean age 62.1 years) with persistent insomnia and prolonged BZD use (average duration of 18.9 years), who had successfully discontinued BZD following CBT for insomnia, a supervised medication taper program, or a combined approach. The Kaplan-Meier product-limit method was used to estimate survival time, defined as time between end-of-treatment and relapse or end of follow-up. By the end of the 24-month follow-up, 42.6% of the samples had resumed BZD use. Participants in the Combined (33.3%) and Taper (30.8%) groups relapsed significantly less than their counterparts from the CBT group (69.2%). Survival rates at 3 months were 61.5% (CBT), 100% (Taper), and 80.9% (Combined). At 12 months, they were 38.5%, 83.3%, and 70.8%, respectively; and, at 24 months, they were 28.9%, 64.8% and 64.9%, respectively. Mean survival time was significantly longer for both the Taper (18.6 months, SE = 2.1) and Combined groups (12.6 months, SE = 1.4), relative to the CBT group (8.5 months, SE = 1.8). Significant predictors of relapse included treatment condition, end of treatment insomnia severity, and psychological distress. In conclusion, there is a substantial relapse rate following BZD discontinuation among prolonged users. CBT booster sessions might enhance compliance with CBT and prove useful in preventing relapse.     

Short-term effects of using verbal instructions and demonstration at the beginning of learning a complex skill in figure skating

This study examined whether providing verbal instructions plus demonstration and task repetition facilitates the early acquisition of a sport skill for which learners had a prior knowledge of the individual motor components. After one demonstration of the task by an expert, 18 novice skaters practiced a figure skating jump during a 15-min. period. Subjects were randomly assigned to one of 3 groups: a group provided with a verbal instruction that specified the subgoals of the task (Subgoals group), a group provided with a verbal instruction that used a metaphor (Metaphoric group), and a group not receiving any specific instruction during training (Control group). Subjects were filmed prior to and immediately following the practice session. Analysis indicated that the modifications of performance were related to the demonstration and the subsequent task repetitions only. Providing additional verbal instructions generated no effect. Therefore, guiding the learner toward a solution to the task problem by means of verbal instruction seems to be ineffective if done too early in the course of learning.     

THE MEASUREMENT OF SUBJECTIVE EXPERIENCES PRESUMABLY RELATED TO HYPNOTIC SUSCEPTIBILITY

Å s , A., O'H ara , J. W. & M unger , M. P. The measurement of subjective experiences presumably related to hypnotic susceptibility. Scand. J. Psychol ., 1962, 3 , 47–64.—An instrument to register a variety of subjective experiences presumably related to hypnotizability was constructed on the basis of certain theoretical notions of hypnosis. A comparison of the responses of 471 college students with the findings of another investigator shows a high degree of response consistency. Some sex differences are discussed. A cluster analysis and a factor analysis of a representative selection of Experience Inventory items and item groups indicate that existing theoretical notions of hypnosis have much in common and may be reduced to a set of very few variables.
