Disentangling similarity judgments from pragmatic judgments: Response to Sloutsky and Fisher (2012)

Sloutsky and Fisher (2012) attempt to reframe the results presented in Noles and Gelman (2012) as a pure replication of their original work validating the similarity, induction, naming, and categorization (SINC) model. However, their critique fails to engage with the central findings reported in Noles and Gelman, and their reanalysis fails to examine the key comparison of theoretical interest. In addition to responding to the points raised in Sloutsky and Fisher's (2012) critique, we elaborate on the pragmatic factors and methodological flaws present in Sloutsky and Fisher (2004) that biased children's similarity judgments. Our careful replication of that study suggests that, rather than measuring the influence of labels on judgments of perceptual similarity, the original design measured sensitivity to the pragmatics of task demands. Together, the results reported in Noles and Gelman and the methodological problems highlighted here represent a serious challenge to the validity of the SINC model specifically and the words-as-features view more generally.

Exploring ownership in a developmental context

Ownership and economic behaviors are highly salient elements of the human social landscape. Indeed, the human world is literally constructed of property. Individuals perceive and manipulate a complex web of people and property that is largely invisible and abstract. In this chapter, the authors focus on drawing together information from a variety of disciplines, including legal theory, philosophy, psychology, and economics, to begin creating a coherent picture of the cognitive architecture that underlies ownership concepts. In doing so, the authors review theories of ownership and discuss recent research that highlights the unique contributions garnered by studying ownership in a developmental context.     

The persistence of object file representations

Coherent visual experience of dynamic scenes requires not only that the visual system segment scenes into component objects but that these object representations persist, so that an object can be identified as the same object from an earlier time. Object files (OFs) are visual representations thought to mediate such abilities: OFs lie between lower level sensory processing and higher level recognition, and they track salient objects over time and motion. OFs have traditionally been studied via object-specific preview benefits (OSPBs), in which discriminations of an object's features are speeded when an earlier preview of those features occurred on the same object, as opposed to on a different object, beyond general displaywide priming. Despite its popularity, many fundamental aspects of the OF framework remain unexplored. For example, although OFs are thought to be involved primarily in online visual processing, we do not know how long such representations persist; previous studies found OSPBs for up to 1500 msec but did not test for longer durations. We explored this issue using a modified object reviewing paradigm and found that robust OSPBs persist for more than five times longer than has previously been tested-for at least 8 sec, and possibly for much longer. Object files may be the "glue" that makes visual experience coherent not just in online moment-by-moment processing, but on the scale of seconds that characterizes our everyday perceptual experiences. These findings also bear on research in infant cognition, where OFs are thought to explain infants' abilities to track and enumerate small sets of objects over longer durations.     

Object files can be purely episodic

Our ability to track an object as the same persisting entity over time and motion may primarily rely on spatiotemporal representations which encode some, but not all, of an object's features. Previous researchers using the 'object reviewing' paradigm have demonstrated that such representations can store featural information of well-learned stimuli such as letters and words at a highly abstract level. However, it is unknown whether these representations can also store purely episodic information (i.e. information obtained from a single, novel encounter) that does not correspond to pre-existing type-representations in long-term memory. Here, in an object-reviewing experiment with novel face images as stimuli, observers still produced reliable object-specific preview benefits in dynamic displays: a preview of a novel face on a specific object speeded the recognition of that particular face at a later point when it appeared again on the same object compared to when it reappeared on a different object (beyond display-wide priming), even when all objects moved to new positions in the intervening delay. This case study demonstrates that the mid-level visual representations which keep track of persisting identity over time--e.g. 'object files', in one popular framework can store not only abstract types from long-term memory, but also specific tokens from online visual experience.     

Preschool-age children and adults flexibly shift their preferences for auditory versus visual modalities but do not exhibit auditory dominance

The goal of this study was to evaluate the claim that young children display preferences for auditory stimuli over visual stimuli. This study was motivated by concerns that the visual stimuli employed in prior studies were considerably more complex and less distinctive than the competing auditory stimuli, resulting in an illusory preference for auditory cues. Across three experiments, preschool-age children and adults were trained to use paired audio-visual cues to predict the location of a target. At test, the cues were switched so that auditory cues indicated one location and visual cues indicated the opposite location. In contrast to prior studies, preschool-age children did not exhibit auditory dominance. Instead, children and adults flexibly shifted their preferences as a function of the degree of contrast within each modality, with high contrast leading to greater use.     

Effects of categorical labels on similarity judgments: a critical analysis of similarity-based approaches

Our goal in the present study was to evaluate the claim that category labels affect children's judgments of visual similarity. We presented preschool children with discriminable and identical sets of animal pictures and asked them to make perceptual judgments in the presence or absence of labels. Our findings indicate that children who are asked to make perceptual judgments about identical items judge discriminable items less accurately when making subsequent similarity judgments. Thus, labels do not generally affect children's perceptual similarity judgments; rather, children's reliance on labels to make similarity judgments appears to be attributable to flaws in the methodological approaches used in prior studies. These results have implications for the role of perceptual and conceptual information in children's categorization and induction.     

Variation in the Application of the “Promiscuous Female” Stereotype and the Nature of the Application Domain: Influences on Sexual Harassment Judgments after Exposure to the Jerry Springer Show

This study was designed to explore how the impact of exposure to a few stereotyped group members can be mediated by individual variation in stereotype application to other group members. When compared to participants exposed to nonpromiscuous women on an episode of the Jerry Springer Show, those exposed to promiscuous women perceived a victim of sexual harassment as less traumatized and more responsible for the event. In addition, exposure condition had no impact on judgments when the man physically touched the victim. Conversely, when he made a verbal comment or verbal request, those in the promiscuous condition reported perceptions of less victim trauma and made greater attributions of victim responsibility. The findings also indicate that the effects of exposure to the promiscuous woman depictions were mediated by individual variation in attributions of victim promiscuity. Finally, activation of the promiscuous female stereotype was also shown to have generalized to judgments of women in a nonsexual domain.     

Development of Children's Awareness of Their Own Thoughts

Adults attach special value to objects that link to notable people or events—authentic objects. We examined children's monetary evaluation of authentic objects, focusing on four kinds: celebrity possessions (e.g., Harry Potter's glasses), original creations (e.g., the very first teddy bear), personal possessions (e.g., your grandfather's baseball glove), and merely old items (e.g., an old chair). Children ages 4 to 12 years old and adults (N = 151) were asked how much people would pay for authentic and control objects. Young children consistently placed greater monetary value on celebrity possessions than on original creations, even when adults judged the two kinds of items to be equivalent. These results suggest that contact with a special individual may be the foundation for the value placed on authentic objects.     

Obstacles to Personal Creativity between Brazilian and Mexican University Students: A Comparative Study

The study focused on personal obstacles to creativity between 385 Brazilian and 305 Mexican university students. The Obstacles to Personal Creativity Inventory, designed and validated by Alencar (1999b), was administered to these students. The results indicated that Lack of Time/Opportunity was the most frequent obstacle. Significant differences were observed between Brazilian and Mexican students in the cluster of obstacles named Lack of Motivation, and between male and female students in the cluster of obstacles named Inhibition/Shyness. The results point to several obstacles to personal creativity which are common among university students. These obstacles should be known by those involved in education in order for them to help students to be less susceptible to obstacles that hinder their creativity.
