A non‐human primate’s understanding of solidity: dissociations between seeing and acting

Studies often reveal a dissociation between what infants know as revealed by action and what they know as revealed by perception. We explored whether non‐human primates exhibit a similar dissociation, focusing on what rhesus macaques know about solidity. In a series of search experiments, Hauser (2001) found that rhesus do not possess a complete understanding of solidity, searching below a solid shelf for an invisibly displaced object. In the present experiments, we explored how rhesus would perform in expectancy violation versions of the same tasks. Subjects looked longer when an apple appeared to fall through a solid shelf and when it appeared to roll through a solid barrier. These results suggest that macaques have some understanding of solidity when tested using looking paradigms even though they do not appear to use this knowledge when searching for food. We speculate that this dissociation is similar to that demonstrated in human development.

Intuitions about gravity and solidity in great apes: the tubes task

We investigated whether great apes, like human infants, monkeys and dogs, are subject to a strong gravity bias when tested with the tubes task, and – in case of mastery – what the source of competence on the tubes task is. We presented 22 apes with three versions of the tubes task, in which an object is dropped down a tube connected to one of three potential hiding places and the subject is required to locate the object. In two versions, apes were confronted with a causal tube that varied in the amount of perceptual information it provided (i.e. presence or absence of acoustic cues). The third version was a non‐causal adaptation of the task in which a painted line ‘connected’ dropping and hiding places. Results indicate that apes neither have a reliable gravity bias when tested with the tubes, nor understand the causal function of the tube. Even though there is evidence that they can integrate tube‐related causal information to localize the object, they seem to depend mainly on non‐causal inferences when searching for an invisibly displaced object.

Searching for the center: spatial cognition in the domestic chick (Gallus gallus)

Chicks learned to find food hidden under sawdust by ground-scratching in the central position of the floor of a closed arena. When tested inan arena of identical shape but a larger area, chicks searched at 2 different locations, one corresponding to the correct distance (i.e., center) in the smaller (training) arena and the other to the actual center of the test arena. When tested in an arena of the same shape but a smaller area, chicks searched in the center of it. These results suggest that chicks are able to encode information on the absolute and relative distance of the food from the walls of the arena. After training in the presence of a landmark located at the center of the arena, animals searched at the center even after the removal of the landmark. Marked changes in the height of the walls of the arena produced some displacement in searching behavior, suggesting that chicks used the angular size of the walls to estimate distances.

Dealing constructively with negatively evaluated emotional situations: the key to understanding the different reactions of teachers with high and low levels of emotional intelligence

Recent work on the distinctive features of emotions appraised as either negative or positive has links to the investigation of differences in levels of emotional intelligence. In a study with experienced teachers as participants, it was found that emotional reactions to positive or negative situations was moderated by level of emotional intelligence. The reactions to positively charged emotional situations involving students and peers were similar for teachers with high and low levels of emotional intelligence, although the low level group showed somewhat lower likelihood of making an “emotionally intelligent” response compared to the high level group. A much sharper contrast in response likelihood was found for negatively charged emotional situations involving students and peers. Teachers with high levels of emotional intelligence responded quite differently to those with low levels of emotional intelligence. The results indicate the prospect of clarifying a neglected area of exploration of differences in the likely behaviour of teachers differing in levels of emotional intelligence.     

Nostalgic recollections of high and low narcissists

Two functions of nostalgia are consistently documented in the literature: self-positivity and social connectedness. These reflect agency and communion, respectively. Such dimensions are polarized no more than in narcissists, who are high in agency and low in communion. In three studies we tested whether high and low narcissists differ in the content of nostalgic recollections, whether they become nostalgic about different objects, and whether nostalgia serves different functions for them. High (versus low) narcissists made more agentic references in their narratives and manifested nostalgic proclivity toward agentic objects. Furthermore, nostalgia served a self-positivity function, but not a social connectedness function, for high (versus low) narcissists. Findings highlight the relevance of personality—narcissism, in particular—for the experience of nostalgia.     

Invisible displacement understanding in domestic dogs (<Emphasis Type="Italic">Canis familiaris</Emphasis>): the role of visual cues in search behavior

Recently, (Collier-Baker E, Davis JM, Suddendorf T (2004) J Comp Psychol 118:421–433) suggested that domestic dogs do not understand invisible displacements. In the present study, we further investigated the hypothesis that the search behavior of domestic dogs in invisible displacements is guided by various visual cues inherent to the task rather than by mental representation of an object’s past trajectory. Specifically, we examined the role of the experimenter as a function of the final position of the displacement device in the search behavior of domestic dogs. Visible and invisible displacement problems were administered to dogs (N = 11) under two conditions. In the Visible-experimenter condition, the experimenter was visible whereas in the Concealed-experimenter condition, the experimenter was visibly occluded behind a large rigid barrier. Our data supported the conclusion that dogs do not understand invisible displacements but primarily search as a function of the final position of the displacement device and, to a lesser extent, the position of the experimenter.

Relations between high and low power groups: the importance of legitimacy

Using a social identity perspective, two experiments examined the effects of power and the legitimacy of power differentials on intergroup bias. In Experiment 1, 125 math-science students were led to believe that they had high or low representation in a university decision-making body relative to social-science students and that this power position was either legitimate or illegitimate. Power did not have an independent effect on bias; rather, members of both high and low power groups showed more bias when the power hierarchy was illegitimate than when it was legitimate. This effect was replicated in Experiment 2 (N = 105). In addition, Experiment 2 showed that groups located within an unfair power hierarchy expected the superordinate power body to be more discriminatory than did those who had legitimately high or low power. The results are discussed in terms of their implications for group relations.     

Becoming irreplaceable: How comparisons to the partner’s alternatives differentially affect low and high self-esteem people

It is proposed that people are motivated to feel hard to replace in romantic relationships because feeling irreplaceable fosters trust in a partner’s continued responsiveness. By contrast, feeling replaceable motivates compensatory behavior aimed at strengthening the partner’s commitment to the relationship. A correlational study of dating couples and two experiments examined how satiating/thwarting the goal of feeling irreplaceable differentially affects relationship perception and behavior for low and high self-esteem people. The results revealed that satiating the goal of feeling irreplaceable increases trust for people low in self-esteem. In contrast, thwarting the goal of feeling irreplaceable increases compensatory behaviors meant to prove one’s indispensability for people high in self-esteem.     

Self‐awareness and self‐understanding

In this paper, I critically examine Dan Zahavi's multidimensional account of the self and show how the distinction he makes among “pre‐reflective minimal,” “interpersonal,” and “normative” dimensions of selfhood needs to be refined in order to accommodate what I call “pre‐reflective self‐understanding.” The latter is a normative dimension of selfhood manifest not in reflection and deliberation, but in the habits and style of a person's pre‐reflective absorption in the world. After reviewing Zahavi's multidimensional account and revealing this gap in his explanatory taxonomy, I draw upon Heidegger, Merleau‐Ponty, and Frankfurt in order to sketch an account of pre‐reflective self‐understanding. I end by raising an objection to Zahavi's claim for the primitive and foundational status of pre‐reflective self‐awareness. To carve off self‐awareness from the self's practical immersion in a situation where things and possibilities already matter and draw one to act is to distort the phenomena. A more careful phenomenology of pre‐reflective action shows that pre‐reflective self‐awareness and pre‐reflective self‐understanding are co‐constitutive, both mutually for each other and jointly for everyday experience.
