Picture-object recognition in pigeons: evidence of representational insight in a visual categorization task using a complementary information procedure

Success in tasks requiring categorization of pictorial stimuli does not prove that a subject understands what the pictures stand for. The ability to achieve representational insight is by no means a trivial one because it exceeds mere detection of 2-D features present in both the pictorial images and their referents. So far, evidence for such an ability in nonhuman species is weak and inconclusive. Here, the authors report evidence of representational insight in pigeons. After being trained on pictures of incomplete human figures, the birds responded significantly more to pictures of the previously missing parts than to nonrepresentative stimuli, which demonstrates that they actually recognized the pictures' representational content.     

Boltzmann's Philosophy Notes for Three Lectures (Fall 1903)

It is necessary to distinguish between Boltzmann’s original lecture notes, his extemporaneous lectures, the fair copy of philosophy lectures 3 to 18 by an unknown hand which are mostly on mathematics, and the multi-published versions which only include lectures 1 and 2. There is a difference between his real thought in his notes (or “honne” in Japanese) and what seems to have survived in lectures 1 and 2 for public consumption (“tatamae”). We have stuck with honne, but where it is too abbreviated to make initial sense, we have put it in grammatical and intelligible form as what we think he most probably intended or believed. It was precisely his linguistic philosophy and the relativistic and pragmatic way of presenting it which was largely suppressed or at least toned-down in the fair copy and published versions. Listeners remembered how witty he was when speaking, and the shortened published accounts are also interesting, but his first thoughts, his honne, before prudence set in will interest most readers, though alas as happens with notes there is also some extraneous material. In translating most of the notes for the first three lectures we have ended where mathematics begins to predominate. This revised version was published online in June 2006 with corrections to the Cover Date.     

Improving the driving practices of pizza deliverers: Response generalization and moderating effects of driving history

A practical intervention program, targeting the safety belt use of pizza deliverers at two stores, increased significantly the use of both safety belts (143% above baseline) and turn signals (25% above baseline). Control subjects (i.e., pizza deliverers at a third no-intervention store and patrons driving to the pizza stores) showed no changes in belt or turn signal use over the course of 7-month study. The intervention program was staggered across two pizza stores and consisted of a group meeting wherein employees discussed the value of safety belts, received feedback regarding their low safety belt use, offered suggestions for increasing their belt use, and made a personal commitment to buckle up by signing buckle-up promise cards. Subsequently, employee-designed buckle-up reminder signs were placed in the pizza stores. By linking license plate numbers to individual driving records, we examined certain aspects of driving history as moderators of pre- and postintervention belt use. Although baseline belt use was significantly lower for drivers with one or more driving demerits or accidents in the previous 5 years, after the intervention these risk groups increased their belt use significantly and at the same rate as drivers with no demerits or accidents. Whereas baseline belt use was similar for younger (under 25) and older (25 or older) drivers, younger drivers were markedly more influenced by the intervention than were older drivers. Individual variation in belt use during baseline, intervention, and follow-up phases indicated that some drivers require more effective and costly intervention programs to motivate their safe driving practices.     

The visual system supports online translation invariance for object identification

The ability to recognize the same image projected to different retinal locations is critical for visual object recognition in natural contexts. According to many theories, the translation invariance for objects extends only to trained retinal locations, so that a familiar object projected to a nontrained location should not be identified. In another approach, invariance is achieved “online,” such that learning to identify an object in one location immediately affords generalization to other locations. We trained participants to name novel objects at one retinal location using eyetracking technology and then tested their ability to name the same images presented at novel retinal locations. Across three experiments, we found robust generalization. These findings provide a strong constraint for theories of vision.     

Evidence of heterospecific referential communication from domestic horses (<Emphasis Type="Italic">Equus caballus</Emphasis>) to humans

Referential communication occurs when a sender elaborates its gestures to direct the attention of a recipient to its role in pursuit of the desired goal, e.g. by pointing or showing an object, thereby informing the recipient what it wants. If the gesture is successful, the sender and the recipient focus their attention simultaneously on a third entity, the target. Here we investigated the ability of domestic horses (Equus caballus) to communicate referentially with a human observer about the location of a desired target, a bucket of food out of reach. In order to test six operational criteria of referential communication, we manipulated the recipient’s (experimenter) attentional state in four experimental conditions: frontally oriented, backward oriented, walking away from the arena and frontally oriented with other helpers present in the arena. The rate of gaze alternation was higher in the frontally oriented condition than in all the others. The horses appeared to use both indicative (pointing) and non-indicative (nods and shakes) head gestures in the relevant test conditions. Horses also elaborated their communication by switching from a visual to a tactile signal and demonstrated perseverance in their communication. The results of the tests revealed that horses used referential gestures to manipulate the attention of a human recipient so to obtain an unreachable resource. These are the first such findings in an ungulate species.     

Wenn ja,wie lange? – Dauer antiandrogener Behandlung von Sexualstraftätern mit paraphilen Störungen

Background

Since 2010 a total of 15 individually justified, therapeutically accompanied treatment-free intervals from antiandrogenic treatment (ADT) have been carried out in the Forensic Therapeutic Outpatient (FTA) department in Berlin.

Material and methods

This article describes the conditions under which a responsible and legally justifiable cessation of ADT can be carried out.

Results

In all 15 of the investigated stable, forensically rehabilitated patients who had been on long-term psychotherapeutic treatment, no criminally prognostic or clinically relevant destabilization has so far occurred, which would have necessitated cessation of the treatment-free interval with resumption of the antiandrogenic depot medication.

Conclusion

The short-term experiences from the clinical aftercare practice have so far shown that in a strictly structered aftercare setting with continuous clinical monitoring, it is possible to withdraw even long-standing antiandrogenic medication. This is important not least to attest the argumentation for a removal of supervision of conduct in case destabilization does occur. Further long-term longitudinal investigations will be the subject of later publications.

     

作为现象学问题的世界

哲学发端于对世界本源的惊异,可以说,世界问题与哲学本身一样古老.然自19世纪传统哲学接受实证主义方案以来,世界问题已近乎被遗忘.只有到了胡塞尔那里,世界问题才重新被置于哲学运思的核心.在胡塞尔看来,世界起源于意识的成就.世界作为视域总是已预先被给予在我们的经验中,只有澄清了这一普遍视域的起源,现象学从主体性的意向成就出发去揭示世界起源的任务才能被完成,而这只有在实行了现象学还原以后的构造性分析中才能实现.胡塞尔的分析首先着力于澄清前哲学的对世界的理解,这样做的主要目的是要获得先验现象学对世界进行构造分析的主导线索,借以通达现象学意义上的世界概念.
