Redundant food searches by capuchin monkeys (Cebus apella): a failure of metacognition?

This study investigated capuchin monkeys' understanding of their own visual search behavior as a means to gather information. Five monkeys were presented with three tubes that could be visually searched to determine the location of a bait. The bait's visibility was experimentally manipulated, and the monkeys' spontaneous visual searches before tube selection were analyzed. In Experiment 1, three monkeys selected the baited tube significantly above chance; however, the monkeys also searched transparent tubes. In Experiment 2, a bent tube in which food was never visible was introduced. When the bent tube was baited, the monkeys failed to deduce the bait location and responded randomly. They also continued to look into the bent tube despite not gaining any pertinent information from it. The capuchin monkeys' behavior contrasts with the efficient employment of visual search behavior reported in humans, apes and macaques. This difference is consistent with species-related variations in metacognitive abilities, although other explanations are also possible.     

Exploring consumers' health meaning categories: towards a health consumption meaning model

• Health marketplace offers a lucrative business for many companies. However, there is a gap in consumer research in understanding what health as a target of consumption really means to consumers. The subtleties and multiplicity of meanings rural and urban (both younger and older) consumers attach to health in their everyday lives are empirically explored in this article. Findings of a focus group interview‐based interpretive analysis are reported. It was found that meanings consumers associate with health are profound and multi‐faceted (identification of several health‐meaning categories) with some evidence for age‐ and area‐of‐ residency‐related health‐meaning differences. The article is concluded by advancing theory‐building in consumer research in the form of developing a tentative framework model that can be used to analyze health consumption meanings.

Children’s eyewitness memory: A comparison of two interviewing strategies as realized by forensic professionals

A critical issue for developmental psychology is how to obtain accurate and complete eyewitness memory reports from preschoolers without offering suggestions that might result in false allegations. We examined effects of two interviewing strategies (police/verbal interviews and clinician/prop-assisted interviews) on young children’s reports about a medical examination. A total of 58 4-year-olds participated in the study, which conformed to a 2 (Interview Type) × 2 (Number of Interviews) factorial design. Analyses revealed that interviewers spent less time off topic and asked more free recall questions in the police/verbal interviews than in the clinician/prop-assisted interviews. Compared with police/verbal interviews, clinician/prop-assisted interviews resulted in significantly more correct rejections and commission errors in children’s memory reports. However, on a final free recall test, error rates were comparable across conditions. Higher child verbal intelligence predicted memory accuracy in police/verbal interviews, and greater parental attachment anxiety predicted children being asked a higher number of misleading questions. The study provides new insights into interview techniques that promote preschoolers’ accurate eyewitness reports.     

Investigating the Effects of a Persuasive Digital Game on Immersion,Identification, and Willingness to Help

Abstract

Recent years have seen a tremendous rise in the development and distribution of persuasive games: digital games that are used to influence players’ attitudes and/or behavior. Three studies (N_{Study 1}?=?134; N_{Study 2}?=?94; N_{Study 3}?=?161) tested the effects of a persuasive game on immersion, identification, and willingness to help. The results showed that playing the persuasive game did not result in substantially stronger willingness to help, relative to the control conditions. Video and printed text resulted in more immersion than the digital game, but playing the game resulted in substantially higher perceptions of embodied presence.     

Dream and loss—on triangulation and its implication on the capacity for self-reflection in psychoanalytic work

This paper takes as its starting point Freud's idea that the loss of the object and its inner restoration is an on-going process, which has a crucial influence on the facing of reality. The author's aim is to illustrate that it is by working through the loss of the object that an inner triangulation may be experienced. The idea of triangulation is based on Ronald Brittens definition of it as the image of a mental space in which subjective experiencing can be combined with observing. Via a clinical material, where the distinction between self and object may be endured only with difficulties, the author discusses how phantasizing may serve as an evasion of a notion of an inner catastrophe and how a collapsed triangular space can be restored. In this discussion, the differentiating aspect by negation is touched upon. In connection to another clinical case, the author discusses how the analysand creates what the author calls an illusion about the mutual inter-changeability of the objects. This is used to protect the analysand from experiencing feelings of Oedipal competition, and through that, mourn the illusion of an exclusive place in the Oedipal triad. The conclusion is that the capacity to create meaning comprises the idea of the possibility of together with the subjective experience, internalizing the perspective of ?the other”. Further, that the working through of the Oedipal situation stabilizes the capacity for an observing thinking, since it places the person in a triangular position where he/she is able both to identify with the parties in the Oedipal arena and to observe hislher own contribution to the Oedipal interplay.     

Imitation promotes affiliation in infant macaques at risk for impaired social behaviors

Parental responsiveness and synchronization during early face‐to‐face interactions between mother and infant have been theorized to affect a broad spectrum of positive developmental outcomes in social and cognitive infant growth and to facilitate the development of a sense of self in the baby. Here we show that being imitated can significantly affect the behavior of nursery‐reared infant monkeys, which are at an increased risk for developing aberrant social behaviors. Infants look longer and lipsmack more at an experimenter both during imitation and after being imitated. These results demonstrate that from early in life imitation might be used as a privileged form of communication by adults to enhance infants' visual engagement and their social communication. Imitation may therefore be useful to counteract the negative effects of early social adversities.     

Evolutionary Relevance and Experience Contribute to Face Discrimination in Infant Macaques (Macaca mulatta)

In human children and adults, familiar face types—typically own-age and own-species faces—are discriminated better than other face types; however, human infants do not appear to exhibit an own-age bias but instead better discriminate adult faces, which they see more often. There are two possible explanations for this pattern: Perceptual attunement predicts advantages in discrimination for the most experienced face types. Additionally or alternatively, there may be an experience-independent bias for infants to discriminate own-species faces, an adaptation for evolutionarily relevant faces. These possibilities have not been disentangled in studies thus far, and these studies did not control infants’ early experiences with faces. In the present study, we tested these predictions in infant macaques (Macaca mulatta) reared under controlled environments, not exposed to adult conspecifics. We measured newborns’ (15–25 days; n = 27) and 6- to 7-month-olds’ (n = 35) discrimination of human and macaque faces at 3 ages—young infants, old infants, and adults—in a visual paired comparison task. We found that 6- to 7-month-olds were the best at discriminating adult macaque faces; however, in the first few seconds of looking, tthey additionally discriminated familiar face types—same-aged peer and adult human faces—thereby highlighting the importance of experience with certain face categories. The present data suggest that macaque infants possess both experience-independent and experientially tuned face biases. In human infants, early face skills may likewise be driven by both experience and evolutionary relevance; future studies should consider both of these factors.     

Does Poor Understanding of Physical World Predict Religious and Paranormal Beliefs?

Although supernatural beliefs often paint a peculiar picture about the physical world, the possibility that the beliefs might be based on inadequate understanding of the non‐social world has not received research attention. In this study (N = 258), we therefore examined how physical‐world skills and knowledge predict religious and paranormal beliefs. The results showed that supernatural beliefs correlated with all variables that were included, namely, with low systemizing, poor intuitive physics skills, poor mechanical ability, poor mental rotation, low school grades in mathematics and physics, poor common knowledge about physical and biological phenomena, intuitive and analytical thinking styles, and in particular, with assigning mentality to non‐mental phenomena. Regression analyses indicated that the strongest predictors of the beliefs were overall physical capability (a factor representing most physical skills, interests, and knowledge) and intuitive thinking style.

Filling in the Gaps: Listening Through Dialogue

Over the past 30 years, technology has been introduced into higher education shifting the ways in which learning and student engagement occurs. While the literature suggests that technology offers benefits for improving educational outcomes, few studies have examined how benefits are achieved. This case study presents how the students and instructor of a course on postmodern theory and family therapy developed a praxis-based approach using a digital platform to improve pedagogy. Specifically, using a reflective approach based on ethnomethodology, this paper presents how the members of this course achieved a transformative generative dialogue using an online, simultaneous multi-user document, file-sharing and editing platform. This paper stresses the importance of all members of a course participating in the use of an interactive technological platform to facilitate open dialogue and collaboration.
