Revisiting the looking at nothing phenomenon: Visual and semantic biases in memory search

When visual stimuli remain present during search, people spend more time fixating objects that are semantically or visually related to the target instruction than looking at unrelated objects. Are these semantic and visual biases also observable when participants search within memory? We removed the visual display prior to search while continuously measuring eye movements towards locations previously occupied by objects. The target absent trials contained objects that were either visually or semantically related to the target instruction. When the overall mean proportion of fixation time was considered, we found biases towards the location previously occupied by the target, but failed to find biases towards visually or semantically related objects. However, in two experiments the pattern of biases towards the target over time provided a reliable predictor for biases towards the visually and semantically related objects. We therefore conclude that visual and semantic representations alone can guide eye movements in memory search, but that orienting biases are weak when the stimuli are no longer present.     

Facelikeness matters: A parametric multipart object set to understand the role of spatial configuration in visual recognition

There is a view that faces and objects are processed by different brain mechanisms. Different factors may modulate the extent to which face mechanisms are used for objects. To distinguish these factors, we present a new parametric multipart three-dimensional object set that provides researchers with a rich degree of control of important features for visual recognition such as individual parts and the spatial configuration of those parts. All other properties being equal, we demonstrate that perceived facelikeness in terms of spatial configuration facilitated performance at matching individual exemplars of the new object set across viewpoint changes (Experiment 1). Importantly, facelikeness did not affect perceptual discriminability (Experiment 2) or similarity (Experiment 3). Our findings suggest that perceptual resemblance to faces based on spatial configuration of parts is important for visual recognition even after equating physical and perceptual similarity. Furthermore, the large parametrically controlled object set and the standardized procedures to generate additional exemplars will provide the research community with invaluable tools to further understand visual recognition and visual learning.     

Seek,and ye shall find: Differences between spontaneous and voluntary analogical retrieval

The present study tackles two overlooked aspects of analogical retrieval: (a) whether argumentation activities elicit a spontaneous search for analogical sources, and (b) whether strategic search can relax the superficial bias typically obtained in experimental studies of analogical retrieval. In Experiment 1, participants had to generate arguments for a target situation under three conditions: without indication to use analogies, with indication to use analogies, and with indication to search for sources within domains provided by the experimenters. Results showed that while voluntary search yields analogical retrievals reliably, the argumentation activity seldom elicits spontaneous remindings. A second set of results demonstrated that the superficial bias can be strategically relaxed, leading to a majority of distant retrievals. Experiment 2 replicated this result with the instruction to search within domains different from that of the target, and without providing a list of specific domains. The theoretical and educational implications of these findings are discussed.     

A stimulus set of words and pictures matched for visual and semantic similarity

Researchers in different fields of psychology have been interested in how vision and language interact, and what type of representations are involved in such interactions. We introduce a stimulus set that facilitates such research (available online). The set consists of 100 words each of which is paired with four pictures of objects: One semantically similar object (but visually dissimilar), one visually similar object (but semantically dissimilar), and two unrelated objects. Visual and semantic similarity ratings between corresponding items are provided for every picture for Dutch and for English. In addition, visual and linguistic parameters of each picture are reported. We thus present a stimulus set from which researchers can select, on the basis of various parameters, the items most optimal for their research question.     

Stimulus Parameters Underlying Sound-Symbolic Mapping of Auditory Pseudowords to Visual Shapes

Sound symbolism refers to non-arbitrary mappings between the sounds of words and their meanings and is often studied by pairing auditory pseudowords such as “maluma” and “takete” with rounded and pointed visual shapes, respectively. However, it is unclear what auditory properties of pseudowords contribute to their perception as rounded or pointed. Here, we compared perceptual ratings of the roundedness/pointedness of large sets of pseudowords and shapes to their acoustic and visual properties using a novel application of representational similarity analysis (RSA). Representational dissimilarity matrices (RDMs) of the auditory and visual ratings of roundedness/pointedness were significantly correlated crossmodally. The auditory perceptual RDM correlated significantly with RDMs of spectral tilt, the temporal fast Fourier transform (FFT), and the speech envelope. Conventional correlational analyses showed that ratings of pseudowords transitioned from rounded to pointed as vocal roughness (as measured by the harmonics-to-noise ratio, pulse number, fraction of unvoiced frames, mean autocorrelation, shimmer, and jitter) increased. The visual perceptual RDM correlated significantly with RDMs of global indices of visual shape (the simple matching coefficient, image silhouette, image outlines, and Jaccard distance). Crossmodally, the RDMs of the auditory spectral parameters correlated weakly but significantly with those of the global indices of visual shape. Our work establishes the utility of RSA for analysis of large stimulus sets and offers novel insights into the stimulus parameters underlying sound symbolism, showing that sound-to-shape mapping is driven by acoustic properties of pseudowords and suggesting audiovisual cross-modal correspondence as a basis for language users' sensitivity to this type of sound symbolism.     

The challenges of comparative theology: An assessment of Kärkkäinen's Doing the work of comparative theology

Doing the Work of Comparative Theology by Veli-Matti Kärkkäinen seeks to do the work of understanding the parallels, similarities, and differences between Christianity, Judaism, Islam, Hinduism, and Buddhism through comparative theology. Comparative theology differs from comparative religion in that it investigates other religious traditions from the perspective of a particular tradition, rather than approaching all of the traditions from the outside. This approach, however, presents unique challenges, specifically, maintaining the same approach to a topic regardless of the tradition being explored, and presenting each tradition without universalizing the beliefs of the tradition as a whole.     

Core self-evaluation moderates distinctive similarity preference in ideal partner’s personality

This research investigated the moderation effects of core self-evaluation (CSE) on singles’ ideal partner preference, concerning distinctive similarity in personality. The data were collected from singles from three countries (i.e., China, Denmark, and US), and modelled in a multilevel profile analysis. The results show that CSE moderated distinctive profile similarity preference in that people high in CSE preferred higher distinctive profile similarity with their ideal partner. In addition, CSE moderated distinctive trait similarity preference in Emotionality, Extraversion, Agreeableness, and Conscientiousness in that people high in CSE preferred their ideal partner to share higher distinctive similarity on these four traits. Implications and limitations of the research and findings are also discussed.

The Comparative Psychology of Avian Visual Cognition

How do small-brained, highly mobile animals like birds so readily perceive the visual world? Despite the computational complexity of vision, recent behavioral tests have suggested that these evolutionarily distant animals may use visual mechanisms that operate in the same manner as the visual mechanisms of primates. This article reviews new evidence regarding the processes of early vision and object perception in pigeons and considers speculations about the similarities and differences between avian and primate visual cognition.
