An Investigation of Neuronal Integrity in Severe Paediatric Traumatic Brain Injury

Magnetic Resonance Spectroscopy (MRS) and its association with neuropsychological functioning was examined in the chronic injury phase of paediatric traumatic brain injury (TBI). Fifteen children, aged 10-16 years, with severe TBIs were compared with 15 controls, matched for age and gender. The TBI group was found to have significantly lower levels of N-acetyl aspartate (NAA) and Choline (Cho) in the right frontal lobe and generally displayed reduced performances on neuropsychological tests. A correlation between metabolites and reaction times was also obtained. Findings indicate a role of proton MRS as a measure of neuronal integrity following severe paediatric TBI and suggest a potential association of MRS with specific neuropsychological impairments.     

A Positron Emission Tomography (PET) Study of Autobiographical Memory Retrieval

Memory for the experiences of one's life, autobiographical memory (AM), is one of the most human types of memory, yet comparatively little is known of its neurobiology. A positron emission tomography (PET) study of AM retrieval revealed that the left frontal cortex was significantly active during retrieval (compared to memory control tasks), together with activation in the inferior temporal and occipital lobes in the left hemisphere. We propose that this left frontal lobe activation reflects the operation of control processes that modulate the construction of AMs in posterior neocortical networks.     

Demand Characteristics and Self-Report Measures of Imaginary Audience Sensitivity: Implications for Interpreting Age Differences in Adolescent Egocentrism

Self-consciousness during early adolescence has been explained as an outcome of adolescent egocentrism, in which adolescents create an imaginary audience (IA) of attentive, critical peers. The possibility that such self-consciousness might result from contact with peers who are more attentive and critical than those encountered during childhood or adulthood has not been considered. Study I tested whether young adults, who are not theoretically susceptible to IA, could be made to receive high scores on IA and self-consciousness measures by having them complete a procedure in 1 of 3 laboratory conditions—a critical audience, a noncritical audience, or no audience. However, participants in the critical-audience condition received significantly lower IA and self-consciousness scores than participants in the no-audience condition did. Study 2 tested whether the directions given to Study I participants might have been responsible for the unexpected findings. Results indicated that participants instructed to give mature-sounding responses received lower IA/self-consciousness scores than did those asked to report their honest opinions. Together, the results of Studies 1 and 2 indicated that survey measures of IA are subject to demand characteristics and highlighted the need to interpret with caution age differences in IA as traditionally assessed.     

The conceptual distinction between projective identification (Klein) and container-contained (Bion)

This paper describes the use of play in the psychotherapy of a latency child from a severely traumatised background. It considers the meaning of play in relation to the role of the psychotherapist and to psychotherapeutic technique and explores its functions in terms of the child's development. The paper documents the psychotherapist's learning experience about the difficulty of trying to make the ‘right’ interpretations and her consequent realisation of the intrinsic value of play in psychotherapy. In considering these themes, the author explores how, by placing interpretation secondary to play, the therapy enabled the development of the child's creativity and self-agency, facilitating a movement from primarily paranoid–schizoid defences towards the beginnings of a depressive position.     

Gamelike features might not improve data

Many psychological experiments require participants to complete lots of trials in a monotonous task, which often induces boredom. An increasingly popular approach to alleviate such boredom is to incorporate gamelike features into standard experimental tasks. Games are assumed to be interesting and, hence, motivating, and better motivated participants might produce better data (with fewer lapses in attention and greater accuracy). Despite its apparent prevalence, the assumption that gamelike features improve data is almost completely untested. We test this assumption by presenting a choice task and a change detection task in both gamelike and standard forms. Response latency, accuracy, and overall task performance were unchanged by gamelike features in both experiments. We present a novel cognitive model for the choice task, based on particle filtering, to decorrelate the dependent variables and measure performance in a more psychologically meaningful manner. The model-based analyses are consistent with the hypothesis that gamelike features did not alter cognition. A postexperimental questionnaire indicated that the gamelike version provided a more positive and enjoyable experience for participants than the standard task, even though this subjective experience did not translate into data effects. Although our results hold only for the two experiments examined, the gamelike features we incorporated into both tasks were typical of—and at least as salient and interesting as those usually used by—experimental psychologists. Our results suggest that modifying an experiment to include gamelike features, while leaving the basic task unchanged, may not improve the quality of the data collected, but it may provide participants with a better experimental experience.     

Memory for Emotional Content from Entertainment Film: The Role of Subtitles,Sex, and Empathy

A major component of consuming filmed entertainment is vicariously experiencing emotions of the filmed characters, yet little is known about how this occurs. Four experiments assessed memory for emotions felt by characters in extended film clips from either a contemporary farce (Overboard) or a historical drama (Sense and Sensibility) under various conditions of native or foreign language in the dialogue or subtitles. English-speaking participants watched a clip and then assessed on 6-point scales specific positive and negative affect felt by characters at various points during the film. Both positive and negative affect felt by characters in both films were perceived and remembered better in conditions with English sound or subtitles than in conditions with no English channel, although, unexpectedly, spoken dialogue or subtitles alone were equally effective at conveying emotion. Overall, emotion memory from the contemporary farce was better than from the historical drama and was surprisingly good even in conditions with no English, especially for the farce. Conditions with only sound, subtitles, or pictures were very comparable to each other. Participants higher in trait fantasy empathy remembered emotions better. The components of an eventual model of emotional comprehension were sketched.     

Need for closure is associated with urgency in perceptual decision-making

Constant decision-making underpins much of daily life, from simple perceptual decisions about navigation through to more complex decisions about important life events. At many scales, a fundamental task of the decision-maker is to balance competing needs for caution and urgency: fast decisions can be more efficient, but also more often wrong. We show how a single mathematical framework for decision-making explains the urgency/caution balance across decision-making at two very different scales. This explanation has been applied at the level of neuronal circuits (on a time scale of hundreds of milliseconds) through to the level of stable personality traits (time scale of years).     

The Honeymoon is Over: Occupational Relocation and Changes in Mental Health Among United Methodist Clergy

In this study we examine how the process of relocation affects the mental health of United Methodist clergy and the extent to which relocation is associated with changes in clergy perception of the workplace environment and feelings of self-efficacy. We analyzed data from a longitudinal survey of 1375 clergy, one quarter of whom experienced a move between the baseline survey in 2008 and the follow-up survey 2 years later. Contrary to expectations, we find that mental distress decreased for those who recently moved compared to those who had moved 2 years prior. We also find strong evidence of a “honeymoon effect.” Recently relocated clergy report higher levels of self-efficacy and higher workplace morale compared to those who do not relocate. This study underscores the importance of examining the short and longer-term impact of moving on mental distress and presses scholars to consider the ways in which, under certain circumstances, relocation may improve mental health.     

Re-Thinking the Human: Heidegger,Fundamental Ontology,and Humanism

This essay engages with Heidegger’s attempt to re-think the human being. It shows that Heidegger re-thinks the human being by challenging the way the human being has been thought, and the mode of thinking traditionally used to think about the human being. I spend significant time discussing Heidegger’s attempt before, in the final section, asking some critical questions of Heidegger’s endeavour and pointing out how his analysis can re-invigorate contemporary attempts to understand the human being.
