Right hemisphere has the last laugh: neural dynamics of joke appreciation

Understanding a joke relies on semantic, mnemonic, inferential, and emotional contributions from multiple brain areas. Anatomically constrained magnetoencephalography (aMEG) combining high-density whole-head MEG with anatomical magnetic resonance imaging allowed us to estimate where the humor-specific brain activations occur and to understand their temporal sequence. Punch lines provided either funny, not funny (semantically congruent), or nonsensical (incongruent) replies to joke questions. Healthy subjects rated them as being funny or not funny. As expected, incongruous endings evoke the largest N400m in left-dominant temporo-prefrontal areas, due to integration difficulty. In contrast, funny punch lines evoke the smallest N400m during this initial lexical–semantic stage, consistent with their primed “surface congruity” with the setup question. In line with its sensitivity to ambiguity, the anteromedial prefrontal cortex may contribute to the subsequent “second take” processing, which, for jokes, presumably reflects detection of a clever “twist” contained in the funny punch lines. Joke-selective activity simultaneously emerges in the right prefrontal cortex, which may lead an extended bilateral temporo-frontal network in establishing the distant unexpected creative coherence between the punch line and the setup. This progression from an initially promising but misleading integration from left frontotemporal associations, to medial prefrontal ambiguity evaluation and right prefrontal reprocessing, may reflect the essential tension and resolution underlying humor.     

Life Satisfaction in Persons with Late Effects of Polio

To assess satisfaction with life as a whole and with ten domains of life satisfaction in Swedish persons with late effects of polio, to describe the relationship with sex, age, marital status, use of mobility aids and self-perceived needs of instrumental support, and to compare the level of life satisfaction with a Swedish reference sample. A cross-sectional study of 160 persons with verified late effects of polio answered a postal questionnaire including the Life Satisfaction Questionnaire (LiSat-11). A majority were to some degree satisfied with life as a whole and with all the ten domains of life satisfaction. Satisfaction with life as whole was not related to any of the sociodemographic or disability related factors and these factors had few relations to the ten domains of life satisfaction. The respondents were significantly less satisfied with life as a whole and with vocation, leisure, sexual life, activities of daily living, and somatic and psychological health compared to the Swedish reference sample, but were significantly more satisfied with economy and contacts with friends. Men and women with late effects of polio, regardless of age, marital status or disability, can experience a reduced life satisfaction. This emphasises the need to identify potential gaps between these persons’ aspirations and achievements in life and carry out appropriate rehabilitation interventions to enhance their life satisfaction.     

Dynamics of psychoanalytic supervision: a heuristic model

This paper presents a heuristic model for the dynamics of psychoanalytic supervision. It is not a manual for how to perform supervision, but a model for how to identify and think about the complex elements and forces influencing the supervisory process. The point of departure is that psychoanalysis is a composite craft in which seemingly contrary elements like strict rules and creative intuitions have their place and interact. Several aspects of supervision are discussed: aims, learning processes, teaching methods, relationship, emotional atmosphere and evaluation. Competence is given a pivotal place in the model. The main feature of the model is that these aspects of supervision are all seen as suspended in a field of dynamic tensions between phenomena in real or apparent opposition. One example of this is the tension in the supervisory relationship between supervisor as instructor acting as an authority for the candidate whilst being a mentor fostering autonomy in the candidate. It is argued that related kinds of dynamics characterize several aspects of psychoanalytic supervision and that these tensions are inherent in analytic work. In conclusion a key word picture of the model is presented.     

Mind,Mortality and Material Being

Many religiously minded materialist philosophers have attempted to understand the doctrine of the survival of death from within a physicalist approach. Their goal is not to show the doctrine false, but to explain how it can be true. One such approach has been developed by Peter van Inwagen. After explaining what I call the duplication objection, I present van Inwagen’s proposal and show how a proponent might attempt to solve the problem of duplication. I argue that the very features of the view that aid the proponent in responding to the duplication objection entails the possibility of an impossible state of affairs—that two distinct persons can at the same time be identical with the same bundle of material simples. The religiously minded materialist is caught between the horns of a dilemma. One’s view regarding human persons must be robust enough to account for personal identity over time, and so not fall to the duplication objection. At the same time, the view must not entail the possibility of two persons temporarily having complete coincident existence.     

Asymmetrical scepticism towards criminal evidence: The role of goal‐ and belief‐consistency

Previous demonstrations of asymmetrical scepticism (i.e., that investigators perceive evidence inconsistent [vs. consistent] with the focal hypothesis of a case as less reliable) have failed to account for the underlying mechanism. This study examined whether inconsistent evidence is discredited due to its inconsistency with a prior belief or because it conflicts with the goal to reach closure in a case. Police trainees (N = 107) were presented with a homicide case and judged the reliability of incriminating or exonerating evidence while entertaining a ‘guilty’ or ‘innocent’ hypothesis concerning a suspect. Asymmetrical scepticism was observed in the guilty condition, but not in the innocent condition, partially supporting the goal‐consistency explanation. Implications for the organization of criminal investigations are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Investigators under influence: How social norms activate goal‐directed processing of criminal evidence

Previous research has shown that exposure to social information can influence behaviour through the automatic activation of goals. In the first study to examine such influences in a legal setting, an experiment with 104 experienced criminal investigators tested the idea that exposure to occupational norms can activate distinct information‐processing goals. As predicted, exposure to norms associated with efficiency (vs. thoroughness) sped up and reduced the depth of investigators' processing of criminal evidence, thus reducing their openness to sequentially late witness evidence. In addition, the goal activation operated outside investigators' awareness, illustrating the insidious cognitive influence of occupational norms. The results are discussed in terms of practical significance and contributions to the goal activation literature and the applied study of criminal investigations.

Variables associated with repeated suicide attempt in a criminal justice population

The aim of this study was to identify factors associated with repeated suicide attempts among criminal justice clients examined for substance abuse using the Addiction Severity Index. Among suicide attempters (n=1,404), repeaters (two or more attempts, n=770) were compared to nonrepeaters. In logistic regression, repetition was associated with younger age, opioid analgesics, somatic medication, overdose, maternal psychiatric problems, delirium tremens, cognitive problems, and violent behavior. As in other settings, factors associated with repetition differed from those associated with suicide attempts in general. In this setting, substance use complications and cognitive problems were connected to repetition and should be addressed in risk assessments.     

Short article Inferring causality assessments from predictive responses: Cue interaction without cue competition

The authors criticize the use of participants' predictive responses during a learning phase as a measure of causal assessments (J. M. Tangen & L. G. Allan, 2003, 2004). Simulations demonstrate that a general aim to minimize error as required in the prediction task will produce results in accordance with those observed, in particular apparent cue interaction effects. It is argued that measures estimated from prediction responses do not reflect causal ratings, but are side-effects of learning explained by adaptation in strategy to changes in presented cell frequencies. The results are reinterpreted to be in line with a causal model view, not requiring dual processes or cue competition of lower level associative processes.
