The present and absent object—on thinking and the capacity to symbolize

In this paper, Bion's different theories on the development of thinking will be introduced: on the one hand, his theory of thoughts as resulting from tolerance for the absence of the object, and on the other hand, dream thoughts and thoughts as resulting from the presence of the object, originally through the mother's containing function. The effects of failures in this development will be discussed; among other things, a hypertrophy of the apparatus of projective identification at the expense of thinking capacities. Briefly, a comparison will be made between a facilitating relation between container and contained and the oscillation between the paranoid-schizoid and depressive position, which Bion describes as a prerequisite for open symbolizing processes. Bion's theories and concepts will be supplemented by Winnicott's theories on the “creative illusion” and the breast/the mother as a “subjective object” as a precondition for the symbolizing capacity that later develops in the “potential space”. Very briefly, a comparison is made between Winnicott's term “the subjective object” and Segal's term “symbolic equation”. Clinical vignettes are interpolated.     

Personality and attitudinal correlates of healthy and unhealthy lifestyles in young adults

Abstract

The relationship between healthy lifestyle and personality and attitudinal variables was analyzed with data collected from 809 men and 996 women aged 18–30 years in England, Belgium, Finland and Norway as part of the European Health and Behaviour Survey. A health practices index was constructed on the basis of performance of sixteen behaviours including smoking, alcohol consumption, exercise, sleep time and a variety of dietary and preventive practices. Scores on the health practices index were higher in women than men, but in both sexes the index was normally distributed. Consistently healthy practices were positively correlated with extraversion and optimism, and negatively associated with neuroticism, psychoticism and chance locus of control beliefs. These effects were maintained after controlling for social desirability, but together accounted for only a modest proportion of the variance in the health practices index. The results are discussed in relation to the factors characterising health conscious and unhealthy lifestyles.     

Web-based training improves on-field offside decision-making performance

ObjectiveThe present study examined to what extent off-field offside decision-making training transfers to real-life offside situations.Design/methodsEighteen Belgian assistant referees were included in the experiment. Ten assistant referees (i.e., training group) were exposed to a pre- and posttest and, in between, four off-field offside training sessions via a web-based training protocol. The remaining eight assistant referees participated in the control group and only completed the pre- and posttest. During both test sessions, which were conducted separately for each group, both an on- and off-field offside decision-making test was completed.ResultsFirst, an increase in response accuracy and a decrease in flag errors were observed for the training group from pre- to posttest in both the on- and off-field offside test. Second, only the training group improved in the recall and recognition accuracy of the position of the receiving attacker at the moment of the pass.ConclusionsThis study demonstrates that perceptual-cognitive skill training results in a positive and direct transfer to on-field offside decisions. Therefore, the structure and the content of the current training intervention mimics the perceptual difficulties of real-match situations and can help the assistant referees to mediate and enhance their offside decision-making skills, both on- and off-field.     

Effects of anxiety on handgun shooting behavior of police officers: a pilot study

Abstract

The current pilot study aimed at providing an initial assessment of how anxiety influences police officers’ shooting behavior. Seven police officers participated and completed an identical shooting exercise under two experimental conditions: low anxiety, against a non-threatening opponent, and high anxiety (HA), against a threatening opponent who occasionally shot back using colored soap cartridges. Measurements included shooting accuracy, movement times, head/body orientation, and blink behavior. Results showed that under HA, shooting accuracy decreased. Underlying this degradation of performance, participants acted faster and made themselves smaller to reduce the chance of being hit. Furthermore, they blinked more often, leading to increases in the amount of time participants had their eyes closed. Findings provide support for attentional control theory, hereby also pointing to possible interventions to improve police officers’ shooting performance under pressure.     

Automaticity and the Amygdala: Nonconscious Responses to Emotional Faces

The human face is an evolved adaptation for social communication. This implies that humans are genetically prepared to produce facial gestures that are automatically decoded by observers. Psychophysiological data demonstrate that humans respond automatically with their facial muscles, with autonomic responses, and with specific regional brain activation of the amygdala when exposed to emotionally expressive faces. Attention is preferentially and automatically oriented toward facial threat. Neuropsychological data, as well as a rapidly expanding brain-imaging literature, implicate the amygdala as a central structure for responding to negative emotional faces, and particularly to fearful ones. However, the amygdala may not be specialized for processing emotional faces, but may instead respond to faces because they provide important information for the defense appraisal that is its primary responsibility.     

The Face of Wrath: Critical Features for Conveying Facial Threat

We examined the role of different facial features (shape of eyebrows, eyes, mouth, nose, and the direction of gaze) in conveying the emotional impact of a threatening face. In two experiments, a total of 100 high school students rated their impression of two sets of schematic faces in terms of semantic differential scales (Activity, Negative Evaluation, and Potency). It was found that the different facial features could be ordered hierarchically, with eyebrows as the most important feature, followed by mouth and eyes. Eyebrows thus fundamentally categorised faces as threatening or nonthreatening. The different shapes of mouth and eyes provided subsequent categorisations of faces within these primary categories.     

Dissociations between word priming effects in normal subjects and patients with memory disorders: Multiple memory systems or retrieval?

Repetition priming was measured in two different tasks within a single experiment--one in which subjects named briefly (tachistoscopically) presented words, and one requiring naming of visually fragmented/degraded words. Thirteen amnesic patients, 12 patients with Alzheimer's disease (AD), and 15 normal control subjects were tested under 4 experimental conditions involving the factorial combination of two variables: delay of test (10 minutes and 24 hours), and number of prior occurrences of the primed items (1 and 4). The two tasks produced very different patterns of priming effects, despite the fact that common study phases were employed. In one task the priming effect showed no decay and virtually no effect of the number of prior occurrences of the primed items, whereas both these variables affected priming in the other task. The AD patients evidenced impaired priming in both tasks. However, in the degraded-word-naming task the deficit was only apparent under some experimental conditions. The amnesics produced priming effects that in absolute terms were similar to those produced by control subjects. However, when group differences in overall performance level were taken into account in the tachistoscopic task, these patients also showed clear evidence of impaired priming. It is argued that the complex pattern of priming effects obtained is best explained by the characteristics of the retrieval cues provided in the tasks, and, generally, that such characteristics may determine whether or not experimental variables will affect measured priming.     

Longitudinal evidence linking processing speed to the development of reasoning

Age‐related change in processing speed has been linked directly to increases in reasoning as well as indirectly via increases in the capacity of working memory (WM). Most of the evidence linking change in speed to reasoning has come from cross‐sectional research; in this article we present the findings from a 2½‐year longitudinal study of 277 6‐ to‐13‐year‐olds. On three occasions, speed of information processing was assessed with Visual Matching and Cross Out; WM was assessed with reading, listening, backward digit, alphabet, and operation span tasks; and nonverbal reasoning was assessed with Raven's progressive matrices. The results provided consistent evidence of direct links from processing speed to reasoning but inconsistent evidence for indirect links from speed to WM to reasoning. These findings suggest that variations in processing speed may constrain the development of reasoning, directly and perhaps indirectly.

Coping With Strain (CWS) course – its effects on depressive symptoms: A four‐year longitudinal randomized controlled trial

The Coping With Strain (CWS) course is a modification of the Coping With Depression (CWD) course. CWD is by far the most studied psycho‐educational intervention to reduce and prevent depression, but CWD has never been tested in a randomized controlled trial in the workplace. This study seeks to examine the extent to which CWS, on a short‐term and a long‐term basis, reduces depressive symptoms in employees. After advertising at workplaces, 119 employees were randomized into Intervention Group I (IG1), which immediately participated in CWS, or Intervention Group II (IG2), which functioned as a control group for six months until its participation in CWS. The follow up period lasted for four years in both IG1 and IG2. Linear mixed models were fitted to the data. Depressive symptoms were significantly reduced during the course. The reduction of depressive symptoms was maintained over a period of four years in both IG1 and IG2, although there is a slight increase towards the end of the follow‐up period. CWS is effective in reducing depressive symptoms among employees. The effects are long lasting and may be maintained over a period of four years.     

Decision making in the prisoner's dilemma game: The effect of exit on cooperation and social welfare

The prisoner's dilemma game is a mixed‐motive game that offers two players the simultaneous choice between a cooperative and a defective alternative. An often neglected aspect of such a binary‐choice game, however, is that in many real‐life encounters, people can choose not only to cooperate or defect, but they also have a third option: to exit the social dilemma. Although in the literature a consensus has emerged that the addition of an exit opportunity benefits cooperation, there is only scant research into its effect on social welfare. In order to allow a direct comparison of cooperation rates and welfare levels across binary‐choice and trinary‐choice games, in this study, we used a design in which the same participants played similar games with and without an exit option (i.e., a within‐subjects design), and this in a range of structural variations. The findings of our study indicated that the aggregated outcome of both players is generally lower in games with an exit option than in games without an exit option. Moreover, our results showed that the efficiency of the exit option strongly depends on the specific outcome structure of the game (in terms of its endowment size, (a)symmetry, and level of noncorrespondence). In the discussion, it is argued that the implementation of an exit option as a strategy to increase social welfare should be critically assessed.
