| Title | Social competition in rats: Cell proliferation and behavior | Type | Journal Article | ||
| Year | 2006 | Publication | Behavioural Brain Research | Abbreviated Journal | Behav. Brain. Res. |
| Volume | 175 | Issue | 2 | Pages | 343-351 |
| Keywords | Social stress; Depression; Forced swim test; Neurogenesis | ||||
| Abstract | Behavioral and physiological changes were studied following prolonged exposure to social competition in pairs of non-food-deprived rats competing daily for a limited supply of graham cracker crumbs. Stable dominant-subordinate relationships developed in most pairs, as measured by feeding time, which were maintained over a 5-6-week study period. In other behavioral tests, subordinates demonstrated a decreased latency to immobility in the forced swim test compared with dominants, but no difference in locomotor activity. Subordinates had increased bladder size, decreased adrenal gland size, and a 35% reduction of hippocampus cell proliferation compared with the dominant member. Therefore, prolonged social competition, based on restricted access to palatable substances, produced hierarchies among individuals that were associated with differences in behavior, physiology and hippocampal cell proliferation. | ||||

| Title | Laterality of flipper rubbing behaviour in wild bottlenose dolphins (Tursiops aduncus): Caused by asymmetry of eye use? | Type | Journal Article | ||
| Year | 2006 | Publication | Behavioural Brain Research | Abbreviated Journal | Behav. Brain. Res. |
| Volume | 170 | Issue | 2 | Pages | 204-210 |
| Keywords | Indo-Pacific bottlenose dolphin; Tursiops aduncus; Social behaviour; Contact behaviour; Flipper rubbing; Behavioural laterality; Eye use; Cerebral asymmetry | ||||
| Abstract | To determine whether wild Indo-Pacific bottlenose dolphins (Tursiops aduncus) at Mikura Island, Japan, show asymmetry of eye or flipper use during a social behaviour, we investigated the laterality of flipper-to-body (F-B) rubbing, in which one dolphin (“rubber”) rubs the body of another (“rubbee”) with its flipper. We analysed 382 episodes of video-recorded F-B rubbings performed by identified individuals (N = 111 rubbers). F-B rubbing was conducted significantly more frequently with the left flipper than with the right flipper. The duration of F-B rubbings was also significantly longer with the left flipper than with the right flipper. Of 20 dolphins, nine individuals showed significant left-side bias as the rubber in this behaviour, whereas no dolphins showed significant right-side bias. The results indicate a population-level left-side bias of the rubber in F-B rubbing. An analysis of the swimming configurations during this behaviour suggests that the asymmetry in F-B rubbing was caused not only by the laterality of the rubber, but by a preference for use of the left eye in both dolphins during this behaviour. Dolphins used the left eye significantly more frequently than the right eye during the inquisitive behaviour, while they showed no significant bias in flipper use during the object-carrying behaviour. These facts also suggest that the asymmetry of F-B rubbing is caused by the preference for using the left eye. Significant left-side bias was observed only in F-B rubbings initiated by the rubbee, in which the rubbee determined its position during this behaviour. This suggests that this behavioural asymmetry was enhanced by the rubbees choosing the left side of the rubber to ensure better and longer rubs. | ||||

| Title | The Rider's Impacts and Their Timers – Example: Rider's Aids for Transitions Between Different Gaits. | Type | Journal Article | ||
| Year | 2006 | Publication | Tierärztliche Umschau | Abbreviated Journal | Tierärztl. Umschau |
| Volume | 10 | Issue | Pages | 515-532 | |
| Keywords | Animal-friendly rider-horse communication – signals for changing the footfall – knee-jerk impacts in the single “fitting” moment – singular timer for those – immediate “obedience” | ||||
| Abstract | The scientific investigation of the basics of the inherited riding teachings assists in conserving its values. Riding instructors should be able to teach not only “how” but also “why”. The classic European riding teachings that have developed across the centuries are based on perceptions that have their roots in natural phenomena. They are being mirrored, for instance, in the aids to stimulate the change from one gait to the next. The movements of the horse's trunk and back provide timers for horse-friendly, sensitive aids that create attentive, diligent and happily cooperating horses. |

| Abstract | Zusammenfassung Wissenschaftliches Erfassen von Grundlagen der ererbten Reitlehre hilft, deren Werte zu bewahren. Und Reiten Lehrende dürfen nicht nur das “Wie”, sie sollten auch das “Weshalb” vermitteln können. Die Grundlagen der in Jahrhunderten entstandenen klassischen europäischen Reitlehre beruhen auf der Natur abgelauschten Erkenntnissen. Sie spiegeln sich u. a. in den Hilfen für Übergänge aus einer Gangart in eine andere. Die Bewegungen von Pferderumpf und -rücken liefern den Zeitgeber für jene pferdgerechte, feinfühlige Hilfengebung, die aufmerksam, fleißig und freudig mitarbeitende Pferde schafft. |

| Abstract | Von der Basis bis zum Spitzensport werden Pferde gewaltsam zum “Gehorsam” gebracht oder zur Ausführung von Übungen gezwungen. Aktionen gegen die “Rollkur” oder “Hyperflexion” füllen die Medien. Aber die Wurzel des Übels liegt viel tiefer. Die Grundlage kultivierten Reitens in hoher Harmonie zwischen Mensch und Pferd ist eine feinfühlige, nahezu unsichtbare Hilfengebung, für die Bewegungen des Pferderückens und des Pferderumpfes den Zeitgeber liefern. Das Wissen darum in der Reiterwelt zu verankern, ist noch immer nicht gelungen. | ||||

| Keywords | cultured riding – horse-rider-harmony – sensitive-invisible aids – saving the backs of both horse and rider | ||||
| Abstract | From the base to the top of the sport horses are being coerced into “obedience” or the performance of exercises by force. Campaigns against the “Rollkur” or “Hyperflexion” fill the media. However the root of evil lies a lot deeper. The base of cultured riding in high harmony between horse and rider are sensitive, almost invisible aids which are being timed by the movements of the horse's back and trunk. Anchoring the knowledge of this interrelation in rider's minds has to this day been unsuccessful. | ||||

| Volume | 273 | Issue | 1583 | Pages | 207-215 |

| Abstract | Among mammals, the members of some Orders have relatively large brains. Alternative explanations for this have emphasized either social or ecological selection pressures favouring greater information-processing capacities, including large group size, greater foraging efficiency, higher innovation rates, better invasion success and complex problem solving. However, the focal taxa for these analyses (primates, carnivores and birds) often show both varied ecological competence and social complexity. Here, we focus on the specific relationship between social complexity and brain size in ungulates, a group with relatively simple patterns of resource use, but extremely varied social behaviours. The statistical approach we used, phylogenetic generalized least squares, showed that relative brain size was independently associated with sociality and social complexity as well as with habitat use, while relative neocortex size is associated with social but not ecological factors. A simple index of sociality was a better predictor of both total brain and neocortex size than group size, which may indicate that the cognitive demands of sociality depend on the nature of social relationships as well as the total number of individuals in a group. | ||||

| Title | Obey or not obey? Dogs (Canis familiaris) behave differently in response to attentional states of their owners | Type | Journal Article | ||
| Year | 2006 | Publication | Journal of Comparative Psychology (Washington, D.C. : 1983) | Abbreviated Journal | J Comp Psychol |

| Keywords | Animals; *Attention; Awareness; *Bonding, Human-Pet; *Cooperative Behavior; Cues; Dogs/*psychology; Humans; Motivation; *Nonverbal Communication; Social Perception; *Speech Perception; *Verbal Behavior | ||||
| Abstract | Sixteen domestic dogs (Canis familiaris) were tested in a familiar context in a series of 1-min trials on how well they obeyed after being told by their owner to lie down. Food was used in 1/3 of all trials, and during the trial the owner engaged in 1 of 5 activities. The dogs behaved differently depending on the owner's attention to them. When being watched by the owner, the dogs stayed lying down most often and/or for the longest time compared with when the owner read a book, watched TV, turned his or her back on them, or left the room. These results indicate that the dogs sensed the attentional state of their owners by judging observable behavioral cues such as eye contact and eye, head, and body orientation. | ||||
