A Test of Order-Constrained Hypotheses for Circular Data With Applications to Human Movement Science

Researchers studying the movements of the human body often encounter data measured in angles (e.g., angular displacements of joints). The evaluation of these circular data requires special statistical methods. The authors introduce a new test for the analysis of order-constrained hypotheses for circular data. Through this test, researchers can evaluate their expectations regarding the outcome of an experiment directly by representing their ideas in the form of a hypothesis containing inequality constraints. The resulting data analysis is generally more powerful than one using standard null hypothesis testing. Two examples of circular data from human movement science are presented to illustrate the use of the test. Results from a simulation study show that the test performs well.     

The Sense of Being Dead and of Dying: Some Perspectives

The present communication is made in response to a published study (Lester and Schumacher, 1969) which found no support for hypotheses that schizophrenic women might usefully be conceptualized as dying women, and that schizophrenics (men and women) would have more death themes in their TAT stories than non-schizophrenics. The present authors argue that there is no reason to expect schizophrenic women to feel like dying women, do present empirical data strongly supporting the notion of a relation between feelings of unreality and of deadness, and suggest reasons for Lester and Schumacher's failure to find schizophrenic-nonschizophrenic differences in TAT themes of death.     

Moral reasoning in autistic individuals: a theoretical review / El razonamiento moral en personas con Trastorno del Espectro Autista: una revisión teórica

Abstract

Individuals diagnosed with an Autism Spectrum Disorder (ASD) often find it difficult to attribute mental states to others and to understand their own and others’ behaviour (Theory of Mind, [ToM]/social cognition). These difficulties can affect their moral judgements. The present article focuses on evidence on moral reasoning and ToM, with the aim of analysing theoretical and review research into autism. The weight intention has in moral reasoning and the causal relation between mental states, actions and outcomes is an essential part of this study. Evidence in the field of autism reports how autistic people would not be able to make moral judgements based on the agent’s intention. Instead, they would reason based on the outcomes of the action. For example, this can be translated into misunderstandings, malicious judgements or ‘over-blaming’ in accidental situations (ambiguous valences). These impairments can confirm the association between ToM and moral reasoning.     

Chaotic attractors in the therapeutic system 1

Because little research had been done on the presence and role of latent communication in the context of team‐conducted family therapy, the writers set out to monitor unconscious responses generated under these conditions. Specifically, they investigated an ongoing family treatment situation conducted according to the “reflecting team model.” One team of therapists handles the actual treatment session, while the other observes from behind a one‐way mirror. During the course of a session, the second team makes suggestions to the treatment team either by telephone or by calling the therapists out of the treatment room.

As the project developed, the writers found that the unconscious responses of both family and treatment teams indicated a process at work beyond the conscious intentions of the participants. That is, the therapeutic enterprise was functioning as a dynamical system, whose increasing complexity suggested a self organizing principle at work. This paper traces the development of the system's movement toward greater complexity, identifies the specific interventions that indicate this process, describes how all participants demonstrated a high degree of resonance and synchronization with this overarching‐self organizing pattern. This paper serves to alert therapists to the role of unconscious communication within the therapeutic system and postulates that the generation of form within psychotherapy follows many of the same self organizing processes found in other human and non human systems.     

Basic anxieties affecting psychiatric staff and their attitudes to psychotic patients

SUMMARY

Institutions can be used by their individual members to strengthen mechanisms of defence, especially against early paranoid and depressive anxieties. This is not to imply that institutios become psychotic, but that we would expect to find in them manifestations of unreality, splitting, hostility, suspicion and other forms of maladaptive behaviour which are the equivalent of psychotic symptoms of an individual.

This paper describes some of the attitudes of those who care for psychotic patients in a hospital setting. These attitudes seem to be influenced by basic fears that are provoked by the relationship with the patients and by coming in contact with their needs and disturbance from a position of responsibility. Such fears are accompanied by phantasies and are related to specific defence mechanisms.     

Working Memory Capacity and the Development of Quantitative Central Conceptual Structures

Abstract

This article reconsiders Case’s theory of central conceptual structures (CCS), examining the relation between working memory and the acquisition of quantitative CCS. The lead hypothesis is that the development of working memory capacity shapes the development of quantitative concepts (whole and rational numbers). Study I, with 779 children from preschool to grade 5, validated a measure of the whole number CCS and found that children’s understanding of whole number advances by one developmental level per additional unit of working memory capacity. Study II, with 92 sixth- and seventh-graders, found that a test of the rational number CCS was predicted by working memory capacity and, to a lesser extent, by intrusion errors in the listening span. We also identified 2 subsets of items that demand a capacity of 4 or 5 units, respectively. Overall, the results support Case’s CCS theory and clarify the role of working memory in the acquisition of numerical concepts. The relevance of these results in relation to the current debate is discussed, with extensive connections to other current theories of whole or rational number comprehension.     

Memory Outcome After Pediatric Epilepsy Surgery: Objective and Subjective Perspectives

Memory was investigated in 27 children and adolescents in a longitudinal study before and at one and two years after epilepsy surgery. A comparison group with intractable epilepsy (n = 15), matched in age, sex, age of seizure onset, and IQ, was studied at comparable points in time. Methods included administration of standardized measures of story recall and face recognition, and qualitative interviews to probe the participants’ perceptions of their memory function over time. There was no significant change over time in either group on the standardized measures. Site and laterality of excision, age at surgery, and seizure outcome were not predictive of change within the surgical group. The narratives revealed facets of memory that were problematic in daily life. The objective and subjective results showed low concordance regarding change, possibly due to limitations in the objective measures for capturing semantic and autobiographical memory.     

Positive Correlation Between Serum Interleukin‐1β and State Anger in Rugby Athletes

Recently, several studies reported a relationship between immune system activation and anger expression. Consequently, the aim of this study was to explore immunitary molecular mechanisms that potentially underlie anger expression. To this end, we applied the Frustration—Aggression Theory in a contact sport model, utilizing the nearing of sporting events to trigger anger feelings. In parallel, we evaluated the activation of immune system at mRNA levels. We enrolled 20 amateur rugby players (age ± SD, 27.2 ± 4.5) who underwent psychological assessment to evaluate anger, with the State‐Trait Anger Expression Inventory‐2 (STAXI‐2), before rugby matches; at the same time blood samples were taken to analyze the variations of gene expression by microarray. During the 2 hr before each game, a significant increase was verified in the Rage State (RS) score compared to the score ascertained 72 hr before. At the same time, we found modulation in expression profile, in particular increased expression of gene that encodes interleukin l‐β (IL‐1β). In a regression analysis, RS score was related to IL‐1β, and the potential risk factors age, body mass index, smoking, and drinking. The levels of cytokine were positively and independently related to RS score. Our results suggest that the nearing of sporting event can trigger anger state feelings and activate immune system in rugby players. We propose the IL‐1β as a potential biological marker of anger. However, further research is necessary to clarify the correlation between cytokine and anger. Aggr. Behav. 39 :141‐148, 2013. © 2012 Wiley Periodicals, Inc.     

Acute exercise suppresses judgments of facial emotion intensity

The ability to recognize others’ facial expressions is critical to the social communication of affective states. The present work examined how transient states of high physiological arousal during aerobic exercise influence recognizing and rating morphed facial expressions. Participants exercised at either a low or high work rate. While exercising and then during cool-down and rest periods, participants performed a version of the morphed faces task that involved animated faces changing into or away from five target affective states (happy, surprise, sadness, anger, and disgust); they were asked to stop the animation when the face first corresponded to a target state, and rate its emotional intensity. Results demonstrated no differences in animation stop data, but overall lower ratings of perceived emotion intensity during high versus low work rate exercise; these effects dissipated through cool-down and rest periods. Results highlight important interactions between physiological states and processing emotional information.     

The structure of working memory and how it relates to intelligence in children

This study explored the structure of working memory, and its relationship with intelligence in 176 typically-developing children in the 4th and 5th grades at school. Different measures of working memory (WM), and intelligence (g) were administered. Confirmatory factor analyses showed that WM involves an attentional control system and storage aspects that rely on domain-specific verbal (STM-V) and visuospatial (STM-VS) resources. The structural equation models showed that WM predicts a large portion (66%) of the variance in g, confirming that the two constructs are separable but closely related in young children. Findings also showed that only WM and STM-VS are significantly related to g, while the contribution of STM-V is moderate. Theoretical implications for the relationship between WM and g are discussed.
