Goals need implementation intentions: The model of action phases tested in the applied setting of continuing education

In the present study, the model of action phases (Heckhausen & Gollwitzer, 1987) was applied to the area of continuing education. A subsample of 136 East German participants in the larger study "Active Actions in a Radical Change Situation" rated the expected value of further education, indicated whether they had taken a decision to continue their education (goal intention) and whether they were planning goal-directed actions (implementation intention). Two years later, it was ascertained whether participants had initiated vocational retraining. Findings support the core assumptions of the model. Postdecisional participants endorsed the positive aspects of further education more strongly (implemental mindset) than predecisional participants, who looked at its pros and cons impartially (deliberative mindset). Second, participants were more successful in initiating vocational retraining when they had a goal intention that was additionally furnished with an implementation intention. Findings are discussed with respect to theoretical and practical implications of the distinction between goal setting and goal implementation.     

Do domestic dogs interpret pointing as a command?

Domestic dogs comprehend human gestural communication flexibly, particularly the pointing gesture. Here, we examine whether dogs interpret pointing informatively, that is, as simply providing information, or rather as a command, for example, ordering them to move to a particular location. In the first study a human pointed toward an empty cup. In one manipulation, the dog either knew or did not know that the designated cup was empty (and that the other cup actually contained the food). In another manipulation, the human (as authority) either did or did not remain in the room after pointing. Dogs ignored the human’s gesture if they had better information, irrespective of the authority’s presence. In the second study, we varied the level of authority of the person pointing. Sometimes this person was an adult, and sometimes a young child. Dogs followed children’s pointing just as frequently as they followed adults’ pointing (and ignored the dishonest pointing of both), suggesting that the level of authority did not affect their behavior. Taken together these studies suggest that dogs do not see pointing as an imperative command ordering them to a particular location. It is still not totally clear, however, if they interpret it as informative or in some other way.     

The Adaptive Use of Recognition in Group Decision Making

Applying the framework of ecological rationality, the authors studied the adaptivity of group decision making. In detail, they investigated whether groups apply decision strategies conditional on their composition in terms of task‐relevant features. The authors focused on the recognition heuristic, so the task‐relevant features were the validity of the group members' recognition and knowledge, which influenced the potential performance of group strategies. Forty‐three three‐member groups performed an inference task in which they had to infer which of two German companies had the higher market capitalization. Results based on the choice data support the hypothesis that groups adaptively apply the strategy that leads to the highest theoretically achievable performance. Time constraints had no effect on strategy use but did have an effect on the proportions of different types of arguments. Possible mechanisms underlying the adaptive use of recognition in group decision making are discussed.     

Personality Expression and Impression Formation in Online Social Networks: An Integrative Approach to Understanding the Processes of Accuracy,Impression Management and Meta‐accuracy

In this paper, we investigate personality expression and impression formation processes in online social networks (OSNs). We explore whether, when and why people accurately judge others' personalities (accuracy), successfully manage the impressions that others form of them (impression management) and accurately infer others' impressions of them (meta‐accuracy) at zero acquaintance. On the basis of targets' OSN profiles (N = 103), overall perceiver impressions were collected and compared with targets' self‐view, desired impression and meta‐perception. In addition, independent groups of thin‐slice perceivers based their personality impressions solely on one of four kinds of information within the OSN profiles (profile picture, interests field, group list and notice board), and more than 300 OSN cues (e.g. attractive person and number of friends) were coded. Results showed evidence of accuracy, impression management and meta‐accuracy, but their extent was moderated by the trait (e.g. Big Five and self‐esteem), the kind of information and the interplay of trait and information. Findings could be explained by cue expression and cue utilization processes (lens model analyses). Future prospects for studying personality impressions in online and offline environments are discussed. Copyright © 2013 European Association of Personality Psychology.     

Focus on the essential: all great apes know when others are being attentive

When begging for food, all great ape species are sensitive to a human’s attention. However, studies investigating which cues are relevant for chimpanzees to assess the attentional state of others have produced highly inconsistent results. Some have suggested chimpanzees differentiate attention based on the status of the face or even the eyes, while others have indicated that body posture alone is the relevant cue. Kaminski et al. (Anim Cogn 7:216–223, 2004) compared the behaviour of chimpanzees, bonobos and orangutans while begging for food from a human experimenter who systematically varied his face and body orientation. Their results indicated that both factors, face and body orientation, affect apes’ begging behaviour. The authors claimed that while body orientation provides information about the experimenter’s general disposition to offer food, the visibility of the face provides information about the human’s attentional state. In the current study, we tested this hypothesis with all four great apes species. However, unlike Kaminski et al. (Anim Cogn 7:216–223, 2004), the experimenter was able to hand over food regardless of body orientation. The results show that as soon as the offering of the food was no longer restricted, the orientation of the face became the key factor. Therefore, we present the first evidence that all great ape species are able to assess the attentional state of a recipient based on the orientation of the face.     

Gibbons (Hylobates pileatus, H. moloch, H. lar, Symphalangus syndactylus) follow human gaze, but do not take the visual perspective of others

We investigated four gibbon species of two different genera (Hylobates pileatus, H. moloch, H. lar, Symphalangus syndactylus) in terms of their looking behavior in response to a human who either looked up or looked at the gibbon. Comparing those two conditions, gibbons as a group looked up more when the human was looking up, but they also performed more looks in other directions and thus generally looked more in this condition. Unlike great apes, gibbons did not respond differently between conditions when only the first look on every trial was considered. Furthermore, they did not perform double looks up to check where the human was looking and also did not habituate to the human’s looks up. This suggests that gibbons co-orient with human gaze, but unlike great apes, they do not take the visual perspective of others.
