An asymmetrical relationship between verbal and visual thinking: Converging evidence from behavior and fMRI.

Humans rely on at least two modes of thought: verbal (inner speech) and visual (imagery). Are these modes independent, or does engaging in one entail engaging in the other? To address this question, we performed a behavioral and an fMRI study. In the behavioral experiment, participants received a prompt and were asked to either silently generate a sentence or create a visual image in their mind. They were then asked to judge the vividness of the resulting representation, and of the potentially accompanying representation in the other format. In the fMRI experiment, participants had to recall sentences or images (that they were familiarized with prior to the scanning session) given prompts, or read sentences and view images, in the control, perceptual, condition. An asymmetry was observed between inner speech and visual imagery. In particular, inner speech was engaged to a greater extent during verbal than visual thought, but visual imagery was engaged to a similar extent during both modes of thought. Thus, it appears that people generate more robust verbal representations during deliberate inner speech compared to when their intent is to visualize. However, they generate visual images regardless of whether their intent is to visualize or to think verbally. One possible interpretation of these results is that visual thinking is somehow primary, given the relatively late emergence of verbal abilities during human development and in the evolution of our species.

You see, the ends don't justify the means: visual imagery and moral judgment.

We conducted three experiments indicating that characteristically deontological judgments--here, disapproving of sacrificing one person for the greater good of others--are preferentially supported by visual imagery. Experiment 1 used two matched working memory tasks-one visual, one verbal-to identify individuals with relatively visual cognitive styles and individuals with relatively verbal cognitive styles. Individuals with more visual cognitive styles made more deontological judgments. Experiment 2 showed that visual interference, relative to verbal interference and no interference, decreases deontological judgment. Experiment 3 indicated that these effects are due to people's tendency to visualize the harmful means (sacrificing one person) more than the beneficial end (saving others). These results suggest a specific role for visual imagery in moral judgment: When people consider sacrificing someone as a means to an end, visual imagery preferentially supports the judgment that the ends do not justify the means. These results suggest an integration of the dual-process theory of moral judgment with construal-level theory.

Do object-category selective regions in the ventral visual stream represent perceived distance information?

It is well established that scenes and objects elicit a highly selective response in specific brain regions in the ventral visual cortex. An inherent difference between these categories that has not been explored yet is their perceived distance from the observer (i.e. scenes are distal whereas objects are proximal). The current study aimed to test the extent to which scene and object selective areas are sensitive to perceived distance information independently from their category-selectivity and retinotopic location. We conducted two studies that used a distance illusion (i.e., the Ponzo lines) and showed that scene regions (the parahippocampal place area, PPA, and transverse occipital sulcus, TOS) are biased toward perceived distal stimuli, whereas the lateral occipital (LO) object region is biased toward perceived proximal stimuli. These results suggest that the ventral visual cortex plays a role in representing distance information, extending recent findings on the sensitivity of these regions to location information. More broadly, our findings imply that distance information is inherent to object recognition.

Distance-dependent processing of pictures and words.

A series of 8 experiments investigated the association between pictorial and verbal representations and the psychological distance of the referent objects from the observer. The results showed that people better process pictures that represent proximal objects and words that represent distal objects than pictures that represent distal objects and words that represent proximal objects. These results were obtained with various psychological distance dimensions (spatial, temporal, and social), different tasks (classification and categorization), and different measures (speed of processing and selective attention). The authors argue that differences in the processing of pictures and words emanate from the physical similarity of pictures, but not words, to the referents. Consequently, perceptual analysis is commonly applied to pictures but not to words. Pictures thus impart a sense of closeness to the referent objects and are preferably used to represent such objects, whereas words do not convey proximity and are preferably used to represent distal objects in space, time, and social perspective.

Lay theories of effortful honesty: Does the honesty-effort association justify making a dishonest decision?

Are our moral decisions and actions influenced by our beliefs about how much effort it takes to do the right thing? We hypothesized that the belief that honesty is effortful predicts subsequent dishonest behavior because it facilitates one's ability to justify such actions. In Study 1 (N = 210), we developed an implicit measure of people's beliefs about whether honesty is effortful, and we found that this lay theory predicts dishonesty. In Study 2 (N = 339), we experimentally manipulated individuals' lay theories about honesty and effort and found that an individual's lay theory that honesty is effortful increased subsequent dishonesty. In Study 3, we manipulated (Study 3a; N = 294) and measured (Study 3b; N = 153) lay theories, and then manipulated the strength of situational force that encourages dishonesty, and found that an individual's lay theory influences subsequent dishonesty only in a weak situation, where individuals have more agency to interpret the situation. This research provides novel insights into how our lay theories linking honesty and effort can help us rationalize our dishonesty, independent of whether a particular moral decision requires effort or not.

The effects of psychological distance on abstraction: Two meta-analyses.

Psychological distance and abstraction both represent key variables of considerable interest to researchers across cognitive, social, and developmental psychology. Moreover, largely inspired by construal level theory, numerous experiments across multiple fields have now connected these 2 constructs, examining how psychological distance affects the level of abstraction at which people mentally represent the world around them. The time is clearly ripe for a quantitative synthesis to shed light on the relation between these constructs and investigate potential moderators. To this end, we conducted 2 meta-analyses of research examining the effects of psychological distance on abstraction and its downstream consequences. Across 106 papers containing a total of 267 experiments, our results showed a reliable and medium-sized effect of psychological distance on both level of abstraction in mental representation and the downstream consequences of abstraction. Importantly, these effects replicate across time, researchers, and settings. Our analyses also identified several key moderators, including the size of the difference in distance between 2 levels of a temporal distance manipulation and the dependent variable's capacity to tap processing of both abstract and concrete features (rather than only one or the other). We discuss theoretical and methodological implications, and highlight promising avenues for future research.

The use of visual and verbal means of communication across psychological distance.

The current study investigated the effect of distance on medium preferences in interpersonal communication. Five experiments showed that people's preference for using pictures (vs. words) is increasingly higher when communicating with temporally, socially, or geographically proximal (vs. distal) others. In contrast, preference for words is increasingly higher when communicating with those who were distal. A sixth experiment showed that communication's medium influences distance preferences, such that people's preference for communicating a message to a distant (vs. proximal) target is greater for verbal compared with pictorial communications. A seventh experiment showed that recipients are more likely to heed a sender's suggestions when the medium and distance are congruent. These findings reflect the suitability of pictures for communication with proximal others and words with distal others. Implications of these findings for construal-level theory, perspective taking, embodied cognition, the development of language, and social skills with children are discussed.
