More evidence for a relational shift in the development of analogy: Children's performance on a causal-mapping task

Gentner (1988) has proposed a relational shift whereby children interpret analogy and metaphor first in terms of object similarity and then in terms of relational similarity. Goswami (1996) argues against the relational shift hypothesis, citing as evidence a study performed by Goswami and Brown (1989) in which 3-, 4-, and 6-year-old children were able to correctly complete pictorial A:B::C:? analogies based on familiar causal relations, and, contrary to the predictions of the relational shift hypothesis, made very few object-similarity errors despite the presence of an object-similarity choice. In the present experiment we obtained similarity ratings of Goswami and Brown's stimuli and found that the materials did not contain a true object similarity choice and therefore that study was not an adequate test of the relational shift hypothesis. After appropriate modifications to their methodology, we found that 4- and 5-year-old children's performance was consistent with the relational shift hypothesis: First, object-similarity errors were highly frequent initially and decreased with age; second, the rate of relational (correct) responding increased with age; and third, performance on the analogues was positively related to children's knowledge about the participating causal relations. We conclude by proposing an explanation for the relational shift based on an alignment view of similarity comparison and, further, suggest a new role for object similarity in children's analogical development.     

Interhemisphärischer Transfer visueller Zweifachwahlen bei kommissurotomierten Tauben

Zusammenfassung Die funktionelle Bedeutung kommissuraler Systeme für den visuellen interhemisphärischen Informationsaustausch wurde bei 71 Tauben an monokular gelernten Zweifachwahlen geprüft (instrumentale Konditionierung nach Skinner). 1 Farb- und 4 Form-Diskriminationen (2 oben-unten- und 2 links-rechts-symmetrische Spiegelbildpaare) wurden verwendet. Bei 21 Tauben war die Decussatio supraoptica (DSO) stereotaktisch durchtrennt worden, bei 20 waren die Commissura tectalis (CT) und die Commissura posterior (CP) durchschnitten. Bei 11 Tauben waren alle 3 Verbindungen unterbrochen. Das Ausmaß der Läsionen wurde durch histologische Kontrolle verifiziert. Der interhemisphärische Transfer war nach DSO-Durchtrennung bei der Farb- und den oben-unten-symmetrischen Formzweifachwahlen stark vermindert. Der Transfer sämtlicher Zweifachwahlen war nach CT+CP-Durchtrennung nicht signifikant verschieden von dem der Kontrolltiere. Es wurde erstmals gezeigt, daß mindestens ein Teil der DSO-Fasern bei Vögeln visuelle Information von einer Hirnhälfte zur andern übermittelt.

Interhemispheric transfer of two-choice discrimination in commissurotomized pigeons

Summary The role of avian commissural systems in interhemispheric transfer of monocularly learned visual discriminations was investigated in an instrumental conditioning situation (Skinner). Color and pattern (up-down and left-right mirror-images) were used as stimuli. Stereotaxic lesions were placed in the supraoptic decussation of 21 pigeons, in the tectal and posterior commissures of 20 pigeons. In 11 animals all three connections were interrupted. All lesions were histologically verified. After section of the supraoptic decussation interhemispheric transfer was severely impaired for one color and two up-down mirror-image discriminations. No significant impairment in transfer for color, up-down and left-right mirror-image discriminations followed section of the tectal and posterior commissures. These data demonstrate that at least part of the supraoptic decussation is involved in interhemispheric transfer of visual information.

Mnemic neglect: Selective amnesia of one’s faults

The mnemic neglect model predicts and accounts for selective memory for social feedback as a function of various feedback properties. At the heart of the model is the mnemic neglect effect (MNE), defined as inferior recall for self-threatening feedback compared to other kinds of feedback. The effect emerges both in mundane realism and minimal feedback settings. The effect is presumed to occur in the service of self-protection motivation. Mnemic neglect is pronounced when the feedback poses high levels of self-threat (i.e., can detect accurately one’s weakness), but is lost when self-threat is averted via a self-affirmation manipulation. Mnemic neglect is caused by self-threatening feedback being processed shallowly and in ways that separate it from stored (positive) self-knowledge. The emergence of mnemic neglect is qualified by situational moderators (extent to which one considers their self-conceptions modifiable, receives feedback from a close source, or is primed with improvement-related constructs) and individual differences moderators (anxiety, dysphoria, or defensive pessimism). Finally, the MNE is present in recall, but absent in recognition. Output interference cannot explain this disparity in results, but an inhibitory repression account (e.g., experiential avoidance) can: Repressors show enhanced mnemic neglect. The findings advance research on memory, motivation, and the self.     

The effect of geographic indication in advertising background pictures on product evaluation: The moderating role of familiarity

This study investigates whether geographic indications in the backgrounds of advertising pictures might affect the viewer's evaluation of a product. The findings reveal that participants in the proximal geographic indication evaluated the product more favourably than those in the distal geographic indication when they were exposed to feasibility‐related information. By contrast, participants in the distal geographic indication evaluated the product more favourably than those in the proximal geographic indication when they were exposed to desirability‐related information. However, familiarity with geographic indications eliminated this effect.     

The Impact of Absolute Importance and Processing Overlaps on Prospective Memory Performance

Prospective memory is the ability to remember an intention at an appropriate moment in the future. Prospective memory tasks can be more or less important. Previously, importance was manipulated by emphasizing the importance of the prospective memory task relative to the ongoing task it was embedded in. This resulted in better prospective memory performance but also ongoing task costs. In the present study, we simply instructed one group of participants that the prospective memory task was important (i.e., absolute importance instruction) and compared them with a group with relative importance instructions and a control group. The results showed that absolute importance leads to an increase in prospective memory performance without enhancing ongoing task costs, whereas relative importance resulted in both increased prospective memory performance and ongoing task costs. Thus, prospective memory can be enhanced without ongoing task costs, which is particularly crucial for safety‐work contexts. Copyright © 2015 John Wiley & Sons, Ltd.     

Sustainable Technologies and Transdisciplinary Futures: From Collaborative Design to Digital Fabrication

This paper argues for hands-on, contextual and problem-solving collaborations, that is, for a transdisciplinary approach that establishes direct connections between social and technical disciplines. It is based on our experience as a team of researchers at the Vitruvius Fab Lab (Digital Fabrication Laboratory) of ISCTE-IUL (University Institute of Lisbon, Portugal). The paper presents a particular research and learning initiative–STTF2013 Summer School ‘Sustainable Technologies and Transdisciplinary Futures: From Collaborative Design to Digital Fabrication’, which served as a testbed for our transdisciplinary, critical and open approach. We address its rationale and main challenges, while also discussing recommendations for other transdisciplinary projects striving to integrate social and technical disciplines in research and innovation.     

The Attainment of Self-Consistency Through Gender in Young Children

This paper explores young children's motivation for gender-stereotypical preferences by comparing two theories, both based on Kohlberg's stages of cognitive understanding within the cognitive developmental tradition. The first, elaborated by Kohlberg, suggests that gender-stereotypical preferences are the result of the child's cognitive understanding of the constancy of their gender. The second theory suggests that it is precisely the lack of certainty of gender constancy that influences gender-stereotypical behavior. Data from a cross-sectional study of 100 children sampled during their first year of school, and longitudinal case studies of 10 children during the transition to school, are brought to bear on these two theories. The sample was drawn from a range of working class and middle class home backgrounds. The children were mainly White, with 6% Asian-Indian in the cross-sectional sample, and 1 Asian-Indian child in the longitudinal group. The study finds an association between gender-stereotypical behavior and the attainment of gender constancy, suggesting support for the first theory.
