Expert-novice differences in cognitive and execution skills during tennis competition

This study deals with decision and execution behavior of tennis players during competition. The study is based on the expert-novice paradigm and aims to identify differences between both groups in the decision-making and execution variables in serve and shot actions in tennis. Six expert players (elite Spanish tennis players) and six novice players (grade school tennis players) took part in this study. To carry out this study, the observation protocol defined by McPherson and Thomas in 1989, in which control, decision-making and execution variables were included, was used, where it was applied to the performance of the tennis player in a real match situation. In the analysis, significant differences between experts and novices in decision-making and execution variables are found wherein it can be observed that experts display a greater ability to make the appropriate decisions, selecting the most tactical responses to put pressure on the opponent. Expert tennis players were also able to carry out forceful executions to their opponent with greater efficiency, making the opponent's response to a large extent more difficult. These findings are in accordance with those of McPherson and colleagues.     

Evaluation of bizarre-idiosyncratic thinking scale as a measure of thought disorder in children and adolescents with severe psychiatric disorders

To investigate the prevalence of thought disorder and the possible appropriateness of the Bizarre-Idiosyncratic Thinking Scale for children and adolescents with severe psychiatric disorders, 96 child and adolescent inpatients and day hospital patients, ages 6 to 18 years, at a state psychiatric hospital were rated by review of retrospective records using Marengo and Harrow's 1986 Evaluation of Bizarre-Idiosyncratic Thinking Scale for the presence of thought disorder in the Thematic Apperception Test and Rorschach Inkblot Test responses. Although the Evaluation of Bizarre-Idiosyncratic Thinking Scale had not been previously used with children and adolescents, the analysis suggested possible indications of thought disorder in several diagnostic groups. No significant differences were found on the Rorschach between patients with Schizophrenia and Psychosis, Not Otherwise Specified and those with Attention Deficit Hyperactivity Disorder, Major Depression, and Conduct Disorder. On the basis of the Thinking Scale ratings, the Thematic Apperception Test responses showed significantly higher ratings of thought disorder for patients with Schizophrenia and Psychosis, Not Otherwise Specified. There was no general relation between thought disorder and age or IQ, but schizophrenic patients, aged 13 and older, had more thought disorder than schizophrenic patients who were younger than 13.     

High-fat diets impair spatial learning in the radial-arm maze in mice

It has been suggested that hyperglycemia and insulin resistance triggered by energy-dense diets can account for hippocampal damage and deficits of cognitive behaviour. We wonder if the impairment of learning and memory processes detected in diet-induced obese (DIO) mice is linked to diet composition itself. With this purpose we have evaluated learning performance in mice undergoing a short-term high-fat (HF) treatment, which leads to a pre-obese state characterized by increased adiposity without significant changes of glucose and insulin plasma levels. C57BL/6J mice were fed either a HF (45 kcal% from fat) or control diet (10 kcal% from fat) during 8 weeks. Learning performance was evaluated by using the four-arm baited version of the eight-arm radial maze test (RAM). Mice were trained to learn the RAM protocol and then memory was tested at different time-points. Time spent to consume food placed in baited arms and errors committed to find them were measured in all sessions. DIO mice significantly spent more time in learning the task and made a greater number of errors than controls. Moreover, retention tests revealed that both working and total memory errors were also more numerous in DIO mice. The current results show that short-term DIO impairs spatial learning and suggest that impairment of hippocampal learning elicited by HF diets might be perceptible before metabolic alterations linked to obesity develop.     

The representation of abstract words: why emotion matters

Although much is known about the representation and processing of concrete concepts, knowledge of what abstract semantics might be is severely limited. In this article we first address the adequacy of the 2 dominant accounts (dual coding theory and the context availability model) put forward in order to explain representation and processing differences between concrete and abstract words. We find that neither proposal can account for experimental findings and that this is, at least partly, because abstract words are considered to be unrelated to experiential information in both of these accounts. We then address a particular type of experiential information, emotional content, and demonstrate that it plays a crucial role in the processing and representation of abstract concepts: Statistically, abstract words are more emotionally valenced than are concrete words, and this accounts for a residual latency advantage for abstract words, when variables such as imageability (a construct derived from dual coding theory) and rated context availability are held constant. We conclude with a discussion of our novel hypothesis for embodied abstract semantics.     

Religiosity,coping, and suicidality within the religious Zionist community of Israela thematic qualitative analysis

The relationship between religion and mental health has been the subject of extensive research, particularly in recent years. The issues of coping and suicidality have also been widely studied. Significantly, however, how religious people cope with harsh life situations is an area which has been overlooked. The present study based on 18 semi-structured interviews, analyses have members of the Religious Zionist community in Israel cope with harsh life situations. Although the study confirms the conclusions of previous research – in general religion creates a buffer to suicide – the results showed a relatively low impact of religiosity on coping: in general these religious interviewees found it difficult to access their religiosity during harsh life situations. The paper suggests a range of explanations, for example the complexity of personal and collective identities which characterise this group, or – more significantly – the possibilty that religious coping is not actually absent but is only available in a second, later stage of coping.     

Brief treatment with alprazolam and behavioral guidance in panic disorder

Abstract

Thirty-two patients with panic disorder, with or without agoraphobic limitations, were treated with alprazolam (mean dose 3.5 mg/d) plus brief behavioral guidance in an open study during eight weeks. The sample had a notorious severity in the frequency of panics and phobic avoidance but was only mildly depressed. Before starting treatment the presence of demoralized mood and extensive avoidance were significant indicators of clinical severity, whereas the presence of dizziness as a relevant somatic complaint was not related to higher severity. After eight weeks of treatment a clinical improvement equal to or exceeding 80% of change was obtained in all cases (29) who completed treatment. Ninety-two percent of the patients were panic free at the end of treatment. There were significant reductions in all the scales with comparable declines in the subgroups formed according to the presence or absence of agoraphobic avoidance and demoralization. The data suggested that moderate doses of alprazolam could be a quick and effective treatment for panic-agoraphobic patients in the short term. The behavioral guidance probably helped in reducing agoraphobic avoidance and in obtaining global good effectiveness although this awaits controlled tests. Finally, the similarity in the response to treatment regardless of the presence of extensive avoidance or demoralized mood argues in favor of not considering the different variants of panic-agoraphobic syndrome differently, at least in samples with similar severity to the present one.     

The Impact of Children's Language Ability on Parent Cognitions and Harsh Discipline Practices

This study examined associations between children's language ability and maternal cognitions about the intentionality and aversiveness of child behaviour, and mothers' reported harsh discipline responses to child misbehaviour. We tested associations with each type of cognition separately as well as in a single model to explore their unique associations. Participants included 69 mothers and their 18‐ to 37‐month‐old children. Mothers completed the Parenting Scale and were asked to rate the aversiveness and intentionality cognitions in response to eight common toddler problem behaviours. The Preschool Language Scale was administered to the children by an objective evaluator. A path analysis demonstrated that children's language ability was associated with maternal intentionality cognitions about their children's behaviour, which, in turn, was associated with mothers' harsh discipline. These findings highlight the importance of examining developmental markers of harsh parenting. Copyright © 2013 John Wiley & Sons, Ltd.     

Paradoxical Effects of Warning in the Production of Children's False Memories

The effects of warning on false recognition and associated subjective experience of false recollection and familiarity were investigated in 7- to 13-year-old children and young adults (N = 259) using the Deese-Roediger-McDermott (DRM) paradigm. Two warning conditions (warning with an example of a critical lure and warning without an example of a critical lure) were compared to a control condition, in which no warning was received. We found that 7- to 8-year-olds exhibited higher false recognition in the warning-with-example condition compared with the control condition; in contrast, 12- to 13-year-olds and young adults exhibited reduced false recognition in the warning-with-example condition. No effect of warning was observed in 10- to 11-year-olds. The subjective experience associated with false memories was similar across ages. In contrast, age-related increases in subjective recollection were found for true memories. The processes that enhance or suppress false memories during development are discussed.     

Counselling and psychotherapy as a form of learning: some implications for practice

This paper explores counselling and psychotherapy as a form of learning. Previous experiences may create distortions in meaning-making perspectives, distortions that create templates for evaluating future experience. These templates act as barriers to being open to experience; thus there is an inability to learn from experience. The process of therapy can provide a learning milieu for the exploration and working through of these barriers, with a potential outcome of a return to learning from experience. It is suggested here that intrinsic to the learning milieu created in therapy there are elements of significant, transformative and emotional learning. Therapy is thus a reparative discourse that facilitates a return to learning from experience. A deconstruction of this concept is provided here as a way of developing the exploration of counselling and psychotherapy as a form of learning.
