Conflict of interest in medicine in Lithuania: legal and ethical aspects

The current legal framework within the Lithuanian health system is described including a review of the physician’s autonomy, rights and duties, and patients’ rights including the right to reimbursement. The role of ethical codes and the law are discussed. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.     

Simulationist models of face-based emotion recognition

Recent studies of emotion mindreading reveal that for three emotions, fear, disgust, and anger, deficits in face-based recognition are paired with deficits in the production of the same emotion. What type of mindreading process would explain this pattern of paired deficits? The simulation approach and the theorizing approach are examined to determine their compatibility with the existing evidence. We conclude that the simulation approach offers the best explanation of the data. What computational steps might be used, however, in simulation-style emotion detection? Four alternative models are explored: a generate-and-test model, a reverse simulation model, a variant of the reverse simulation model that employs an "as if" loop, and an unmediated resonance model.     

Affektive Interaktion zwischen Patienten und Therapeuten

Zusammenfassung Eine positive therapeutische Beziehung wird therapieschulenübergreifend als wichtige Voraussetzung für den Therapieerfolg angesehen. Meist wird jedoch in Studien lediglich die schriftliche Patienteneinschätzung erfasst. Nonverbale Aspekte der Interaktion zwischen Patienten und Therapeuten werden kaum untersucht. Aus einer Studie zur Vorhersage des Erfolgs stationärer Fokaltherapie werden affektive Interaktionsprozesse im Erstinterview exemplarisch zwischen einer erfolgreichen und einer nicht erfolgreichen Behandlung mit mikroanalytischen Verfahren (facial action coding system, FACS) verglichen. In der nicht erfolgreichen Therapie waren die mimischen Affektäußerungen reziprok; Therapeutin und Patientin zeigten ähnliche vorherrschende (sog. Leit-)Affekte. Erfolgreicher waren die Behandlungen, wenn die Therapeuten komplementäre Affektmuster zeigten. Implikationen für Behandlungstechnik, Supervision und Weiterbildung werden diskutiert.     

Hostility and facial affect recognition: effects of a cold pressor stressor on accuracy and cardiovascular reactivity

The effects of hostility and a cold pressor stressor on the accuracy of facial affect perception were examined in the present experiment. A mechanism whereby physiological arousal level is mediated by systems which also mediate accuracy of an individual’s interpretation of affective cues is described. Right-handed participants were classified as high hostile (N=28) or low hostile (N=28) using the Cook Medley Hostility Scale. The high-hostile group met joint selection criteria. Only high-hostile participants who showed cardiovascular reactivity to the cold pressor, with systolic BP change exceeding the group mean were included. Groups were further subdivided into cold pressor and non-cold pressor test conditions. It was predicted that high-hostile men, relative to low-hostile men, would show decreased perceptual accuracy when presented with happy, angry, and neutral facial configurations within the left visual field (LVF). Results indicated that high-hostile men were less accurate than low-hostile men in the LVF. Further, pre-stress accuracy scores in the high-hostile men were similar to the post-stress accuracy scores of the low-hostile men. The lateralization of affective function and the role of physiological arousal in affective facial perception are discussed.     

Alcohol-related motivational tendencies in hazardous drinkers: assessing implicit response tendencies using the modified-IAT

This study examined the utility of an implicit measure of cognitive associations, the Implicit Association Test (IAT; ), to assess alcohol-related approach dispositions. Forty-seven hazardous drinkers completed a modified IAT procedure that assessed the relation between alcohol and behavioral categories (i.e., approach and avoid). Participants completed a series of individual difference measures before an alcohol cue exposure task in which they anticipated alcohol consumption. Results indicate that the modified IAT is associated with binge drinking episodes, perceived difficulty controlling alcohol use, and appetitive responses to alcohol cues. Findings are discussed in terms of the potential value of this measure to assess alcohol-related memory associations among those whose alcohol use puts them at risk for harm.     

Representing others' actions: just like one's own?

Previous research has shown that observing others' actions can affect individual performance of the same actions. In the present study, we developed a new paradigm to investigate whether and how complementary actions at the disposal of another agent are represented and influence one's own actions. A spatial compatibility task was distributed among two people so that each participant took care of one of two responses. The identical task was performed alone and alongside another participant. There was a spatial compatibility effect in the group setting only. It was similar to the effect obtained when one person took care of both responses. This result suggests that one's own actions and others' actions are represented in a functionally equivalent way.     

Preference for human direct gaze in infant chimpanzees (Pan troglodytes)

We studied gaze perception in three infant chimpanzees (Pan troglodytes), aged 10-32 weeks, using a two-choice preferential-looking paradigm. The infants were presented with two photographs of a human face: (a) with the eyes open or closed, and (b) with a direct or an averted gaze. We found that the chimpanzees preferred looking at the direct-gaze face. However, in the context of scrambled faces, the infants showed no difference in gaze discrimination between direct and averted gazes. These findings suggest that gaze perception by chimpanzees may be influenced by the surrounding facial context. The relationship between gaze perception, face processing, and the adaptive significance of gaze perception are discussed from an evolutionary perspective.     

Motor facilitation following action observation: a behavioural study in prehensile action

Previous research has shown that the observation of actions and the execution of actions activate common neural systems. More recently, we have presented data showing that action observation of prehension primes subsequent execution (Castiello, Lusher, Mari, Edwards, & Humphreys, 2002). In the current paper we examined action priming under conditions in which the size of the prime did not predict the size of the target (only 20% of trials were valid). We demonstrated reliable priming under these conditions, consistent with the effect occurring automatically. In addition, we show priming even when observers saw just the object rather than the object and a reaching action on the prime trial. We discuss the findings in relation to the role of mirror neurons and object affordances.     

Off-line authorship effects in action perception

Does the perception of our actions differ from the perception of other individuals' actions when we observe them, like other individual's actions, in an offline perspective? Previous studies, using recognition as well as prediction judgments, suggest that it does even if the stimulus information is reduced to a single moving point-light. Here, we assessed whether this difference also affects the timing of actions. This was tested in two experiments, using a specific synchronization task. After some practice, self-generated action events were anticipated faster than other action events, provided that the anticipation could not be accomplished sufficiently well on the basis of easily detectable cues. The results are discussed with regard to the previous findings of off-line authorship effects in action perception.
