Children's ability to control the facial expression of laughter and smiling: Knowledge and behaviour

A total of 64 children, aged 7 and 10, watched a clown performing three sketches rated as very funny by the children. Two experimental conditions were created by asking half of the participants to suppress their laughter. Facial expressions were videotaped and analysed with FACS. For both ages, the results show a significant shorter duration (but not a lower frequency) of episodes of laughter and Duchenne smiles, and greater frequency of facial control movements in the suppression compared to the free expression group. The detailed results on individual facial action units used to control amusement expressions suggest hypotheses on the nature of the underlying processes. The participants' explicit knowledge of their control strategies was assessed through standardised interviews. Although behavioural control strategies were reported equally frequently by the two age groups, 10-year-olds verbalised more mental control strategies than 7-year-olds. This theoretically expected difference was not related to the actual ability to control facial expression. This result challenges the commonly held assumption that explicit knowledge of control strategies results in a greater ability to execute such control in ongoing social interactions.     

“I feel better but I don't know why”: The psychology of implicit emotion regulation

Although emotion regulation has traditionally been conceived as a deliberative process, there is growing evidence that many emotion-regulation processes operate at implicit levels. This special issue of Cognition and Emotion showcases recent advances in theorising and empirical research on implicit emotion regulation. Implicit emotion regulation can be broadly defined as any process that operates without the need for conscious supervision or explicit intentions, and aims at modifying the quality, intensity, or duration of an emotional response. Implicit emotion regulation is likely to be pervasive in everyday life and may contribute considerably to the effectiveness of emotion regulation. Research in this area has developed several valid methods for measuring and manipulating implicit emotion. The contributions to this special issue highlight the significance of implicit emotion regulation in psychological adaptation, goal-directed behaviour, interpersonal behaviour, personality functioning, and mental health.     

The contributions of encoding,retention, and recall to the Hebb effect

The article reports an experiment testing whether the Hebb repetition effect—the gradual improvement of immediate serial recall when the same list is repeated several times—depends on overt recall of the repeated lists. Previous reports which suggest that recall is critical confound the recall manipulation with retention interval. The present experiment orthogonally varies retention interval (0 or 9 s) and whether the list is to be recalled after the retention interval. Hebb repetition learning is assessed in a final test phase. A repetition effect was obtained in all four experimental conditions; it was larger for recalled than non-recalled lists, whereas retention interval had no effect. The results show that encoding is sufficient to generate cumulative long-term learning, which is strengthened by recall. Rehearsal, if it takes place in the retention interval at all, does not have the same effect on long-term learning as overt recall.     

Adaptive Dynamics of the Leg Movement Patterns of Human Infants: I. The Effects of Posture on Spontaneous Kicking

This is the first of two articles in which we describe how infants adapt their spontaneous leg movements to changes in posture or to elicitation of behaviors by a mechanical treadmill. In this article, we compare the kinematics of kicks produced by 3-month-old infants in three postures, supine, angled (45°), and vertical, and examine the changes in muscular and nonmuscular force contributions to limb trajectory. By manipulating posture we were able to assess the sensitivity of the nascent motor system to changes in the gravitational context. The postural manipulation elicited a distinct behavioral and dynamic effect. In the more upright postures, gravitational resistance to motion at the hip was 4 to 10 times greater than resistance met in the supine posture, necessitating larger muscle torques to drive hip flexion. Kicks produced in the vertical posture showed a reduction in hip joint range of motion and an increase in synchronous joint flexion and extension at the hip and knee. At the same time, hip and knee muscle torques were also more highly correlated in kicks performed in the vertical than in the supine or angled posture. This increased correlation between muscle torques at the hip and knee implicates anatomical and energetic constraints—the intrinsic limb dynamics—in creating coordinated limb behavior out of nonspecific muscle activations.     

Psychoanalysis in Psychiatric Institutions - Theoretical and Clinical Approaches

The paper presents historical remarks about psychoanalysis in institutions with a special focus on the contributions of nurses working in psychoanalytic settings. A case report of the forensic psychotherapy ward in Reichenau Mental Hospital, which is organised as a therapeutic community, shows how individual psychotherapy, group psychotherapy and special nursing care contribute to significant progress in the treatment of a severely narcissistic arsonist.     

the scientific association of the lake of constance psychiatrists 1919-1932 psychoanalytic contributions to the treatment of psychoses

Abstract

From 1919 until 1932, psychiatrists from the mental hospitals near Lake Constance and from the Bellevue-Sanatorium in Kreuzlingen/Switzedand organized regular scientific meetings, where well-known representatives of all the relevant psychiatric and psychotherapeutic schools and important phenomen-ologicai philosophers came together. Getting in touch with psychoanalytical and social psychiatric trends led to a quite lively and fruitful exchange in theory and practice. Through the Reichenau psychiatrist Alfred Schwenninger, Ludwig Binswanger got to know personally the phenomenologic philosophers Alexander Pfander and Edmund Husserl, who also held lectures at meetings there. Hans Wolfgang Maier from the Burghölzli in Zurich and his colleagues from Herisau and Munsterlingen concentrated on the mainly social psychiatric and forensic work diey did. Quite a few of the lectures were published in the TZeitschrift für die gesamte Neurologie und Psychiatrie The paper concentrates on contributions related to psychoanalysis. The Reichenau director Karl Wilmanns showed a sceptical sympathy for psychoanalysis even when applied to schizophrenia. Ludwig Binswanger treated psychotic patients psychoanalytically and tried to combine psychoanalysis, clinical psychiatry and philosophy. Especially phenomenology was for him a fundament of psychopathology. The paper reports in detail some of his contributions at the scientific discussions, theoretical issues as well as issues of a psychoanalytic practice.     

Transparency in Structured Interviews: Consequences for Construct and Criterion-Related Validity

Although researchers agree on the use of structured interviews in personnel selection, past research has been undecided on whether these interviews need to be conducted nontransparently (i.e., without giving interviewees any indication of the evaluated criteria) or transparently (i.e., by revealing to interviewees the dimensions assessed in the interview). This article presents two independent studies examining the effects of interview transparency on interviewees' performance and on the interview's construct and criterion-related validity in the context of an application training program. Results from both Study 1 (N = 123) and Study 2 (N = 269) indicate an improvement in interviewees' performance under transparent interview conditions. Both studies further support the assumption that transparent interviews show satisfactory construct validity, whereas nontransparent interviews do not. Moreover, Study 2 showed no significant difference between the interview's criterion-related validity under transparent versus nontransparent conditions. Implications and directions for future research are discussed.     

“I Know What You Want to Know”: The Impact of Interviewees' Ability to Identify Criteria on Interview Performance and Construct-Related Validity

The current study tested whether candidates' ability to identify the targeted interview dimensions fosters their interview success as well as the interviews' convergent and discriminant validity. Ninety-two interviewees participated in a simulated structured interview developed to measure three different dimensions. In line with the hypotheses, interviewees who were more proficient at identifying the targeted dimensions received better evaluations. Furthermore, interviewees' ability to identify these evaluation criteria accounted for substantial variance in predicting their performance even after controlling for cognitive ability. Finally, the interviewer ratings showed poor discriminant and convergent validity. However, we found some support for the hypothesis that the quality of the interviewer ratings improves when one only considers ratings from questions for which interviewees had correctly identified the intended dimensions.     

Visual working memory declines when more features must be remembered for each object

The article reports three experiments investigating the limits of visual working memory capacity with a single-item probe change detection paradigm. Contrary to previous reports (e.g., Vogel, Woodman, & Luck, Journal of Experimental Psychology. Human Perception and Performance, 27, 92–114, 2001), increasing the number of features to be remembered for each object impaired change detection. The degree of impairment was not modulated by encoding duration, size of change, or the number of different levels on each feature dimension. Therefore, a larger number of features does not merely impair memory precision. The effect is unlikely to be due to encoding limitations, to verbal encoding of features, or to chunk learning of multifeature objects. The robust effect of number of features contradicts the view that the capacity of visual working memory can be described in terms of number of objects regardless of their characteristics. Visual working memory capacity is limited on at least three dimensions: the number of objects, the number of features per object, and the precision of memory for each feature.     

Energetic effects of stimulus intensity on prolonged simple reaction-time performance

The efficiency of cognition is modulated by energetic factors like effort, fatigue or circadian variation, which affect even the most basic cognitive operations. For instance, speeded detection in simple reaction-time (SRT) tasks usually slows down over time. The literature suggests that either mindlessness due to routinization or mental fatigue due to attentional resource depletion might underlie this decrement. We tested these assumptions in three 25-min visual SRT tasks using easy-to-detect high-intensity and hard-to-detect low-intensity stimuli presented in both blocked and mixed fashion. Mindlessness theory predicts that less monotonous stimulation (i.e. the mixed presentation) would mitigate the time-related decrement for high- and low-intensity stimuli alike, whereas resource-depletion theory predicts opposite effects of mixed presentation on high- versus low-intensity stimuli. Indeed, stimulus intensity and presentation mode cross-interacted significantly, indicating that the performance decline was steeper for high-intensity stimuli but less steep for low-intensity stimuli during mixed compared to blocked presentation, respectively. These results strongly suggest that the time-related efficiency decrement during prolonged SRT performance is related to accumulating mental fatigue. A conjecture is put forward that explains both resource depletion and mindlessness from the perspective of self-regulation. Our study underscores the need to incorporate energetic factors into models of cognition to facilitate their translation into real-world applications.
