The role of perception, language, and preference in the developmental acquisition of basic color terms

When learning basic color vocabulary, young children show a selective delay in the acquisition of brown and gray relative to other basic color terms. In this study, we first establish the robustness of this finding and then investigate the extent to which perception, language, and color preference may influence color conceptualization. Experimental tasks were designed to measure different aspects of perceptual color processing (discrimination and saliency), color preference and objective counts of color term frequency in preschool-directed language (books and mothers' speech) were used to compare the acquisition of three groups of colors: primary colors, secondary colors (orange, pink, and purple) that appear at the same time as the primary colors, and secondary colors (brown and gray) that appear late. Although our results suggest that perception does not directly shape young children's color term acquisition, we found that children prefer brown and gray significantly less than basic colors and that these color terms appear significantly less often in child-directed speech, suggesting that color preference, linguistic input, and developing color cognition may be linked.     

Adolescents' visual preference for color over form

This study is concerned with the visual preference for color over form among the Yoruba adolescents of Nigeria. The hypothesis is that Yoruba adolescent boys are more likely to demonstrate superior performance in a task involving cultural differences in visual selective attention preference for color over form than girls. One hundred 16-year-old adolescent boys and girls were randomly drawn from two secondary schools for this study. The instrument used was the Visual Selective Attention Color-Form Matching Experiment. Computation was carried out with a chi-square 2 X 2 contingency analysis. Results indicated that the hypothesis reached a .001 statistical level of significance. The theoretical implications of the findings are discussed.     

The role of preference in speed choice

Individual differences with regard to speed preference may be a source of speed heterogeneity and conflicts in traffic, such as tailgating and dangerous overtaking. The main aim of the current study was to explore drivers’ speed preferences when driving for different reasons (saving money on fuel, driving safely, driving for fun or driving as usual) and the relationship of these preferences to observed speeds and self-reported speed. 193 drivers were interviewed at five different locations, and were asked about their speeds on roads they had just travelled. Drivers’ speeds on these roads were also sampled with a speed gun. The results showed large differences between speeds chosen for different driving purposes; the lowest speeds were chosen when the goal was economy and the highest when driving for fun. In addition, there were individual differences in speed preferences such that some drivers indicated that their usual speed was above what they believed was a safe speed while others indicated that they usually drove even slower than what they thought was safe. These differences may account for much of the speed heterogeneity observed in on-road behaviour. The results also showed that drivers’ speed choices are highly influenced by their usual speeds, even more so than their beliefs regarding what constitutes a safe speed, which may help explain non-compliance with speed limits. No relationship was found between speed choice and risk perception.     

Acquisition of spatial antonym pairs

Twenty-eight children (mean age 4.3 yr) were tested for comprehension of spatial antonym pairs with arrays which contained four objects representing both members of two antonym pairs. The results showed that: (a) the most common error was to point to an object representing the same polarity (marked-unmarked) as the word requested; (b) there was not a high degree of confusion within antonym paris; (c) unmarked antonyms tend to be acquired before marked antonyms; and (d) the order of acquisition of the pairs was: tall-short, long-short, high-low, thick-thin, deep-shallow, wide-narrow. The results were interpreted as supporting a modified semantic-feature hypothesis, in which polarity is acquired before dimension.     

Evaluations of pairs of experiences: A preference for happy endings

Experiences often consist of a number of temporally separated events or outcomes, events which might be positive or negative. Building on previous research, the present paper proposes that the chronological order of the component events influences overall evaluations of these experiences. In particular, a preference for happy endings is hypothesized such that an experience consisting of a positive and a negative event is evaluated as more satisfactory if the positive event occurs last. This preference is examined in three studies in a variety of contexts. A preference for happy endings is shown to influence people's preferences, even to the extent of influencing preferences for segregated versus integrated events (Thaler, 1985). The implications of a preference for happy endings for decision researchers are also explored.     

The role of color in high-level vision

Traditional theories of object recognition have emphasized the role of shape information in high-level vision. However, the accumulating behavioral, neuroimaging and neuropsychological evidence indicates that the surface color of an object affects its recognition. In this article, we discuss the research that examines the conditions under which color influences the operations of high-level vision and the neural substrates that might mediate these operations. The relationship between object color and object recognition is summarized in the 'Shape+Surface' model of high-level vision.     

Strategies for spatial organization in adults and children

People have a tendency to organize space by extracting meaningful shapes from the configuration of elements. However, research on spatial correspondence in children suggests that when configural processing is difficult, individuation of elements may be critical. To begin to address the distinction between the use of configurations and individuation, and changes associated with age, we relied upon perceptual grouping and manipulated the colour of the displays—promoting either extraction of configural information (monochromatic) or individuation of elements (multicoloured). In a layout reproduction task (Experiments 1 and 2), children showed a robust advantage for multicoloured arrays, whereas adults showed an attenuated advantage for monochromatic displays. Visual discrimination in adults (Experiment 3) revealed that the influence of the display type occurs at the level of perception. Taken together, these results suggest that there are (at least) two routes to establishing spatial correspondence in arrays of elements, with differential dependence over development.     

The spatial or temporal organization of short-term memory

Children were shown three visually displayed digits. The digits were exposed successively in three windows in such a way, that the left-to-right order never corresponded with the temporal-sequential order. When asked to recall or recognize the digits, normal children responded in terms of temporal order. Deaf, autistic and some subnormal children, recalled or recognized the spatial, i.e. the left-to-right order. The relationship between hearing and/or speech and the temporal ordering of visual displays is discussed.     

The role of the amygdala in conditioned flavor preference

Long-Evans rats with control or amygdala lesions were tested in a conditioned flavor preference task. Half of the rats in each lesion group received an unsweetened grape-flavored solution on odd-numbered days and a sweetened cherry-flavored solution on even-numbered days. The remaining rats received a sweetened grape-flavored solution on odd-numbered days and an unsweetened cherry-flavored solution on even-numbered days. The appropriate solution was presented once a day for 15 min to each rat in the homecage. After six days of testing, each rat received unsweetened cherry and grape flavored solutions simultaneously for 15 min daily across four days. When the two unsweetened flavored solutions were presented simultaneously control rats showed a significant preference for the flavor that was sweetened during training compared to the unsweetened solution. However, amygdala-lesioned rats did not show a preference. The data suggest that the amygdala may be critically involved in mediating reward-based conditioned flavor preference.     

The role of cuing and organization in children's memory for events

Children's memory for a standardized, hierarchically organized event, making clay, was tested in two experiments. Immediately after participating in this event and again 2 weeks later, children described how they had made the clay. In Experiment 1, action and object cues were presented but only action cues greatly facilitated recall. Children who remade the clay reported more information and also reported more of the actions most central to the goal of the event during delayed recall. In Experiment 2, verbal cues representing two levels in the event hierarchy were presented, but neither aided recall. These and other patterns in the data indicated that, at most, the rudiments of a hierarchical structure had emerged after a single experience. These results were discussed in terms of their implications for the development and organization of event memories.     

Patterns of hand preference for pairs of actions and the classification of handedness

Pairs of actions such as write × throw and throw × racquet were examined for items of the Annett hand preference questionnaire (AHPQ). Right (R) and left (L) responses were described for frequencies of RR, RL, LR, and LL pairings (write × throw etc.) in a large representative combined sample with the aim of discovering the distribution over the population as a whole. The frequencies of RL pairings varied significantly over the different item pairs but the frequencies of LR pairings were fairly constant. An important difference was found between primary actions (originally write, throw, racquet, match, toothbrush, hammer with the later addition of scissors for right‐handers) and non‐primary actions (needle and thread, broom, spade, dealing playing cards, and unscrewing the lid of a jar). For primary actions, there were similar numbers of right and left writers using the ‘other’ hand. For non‐primary actions more right‐handers used the left hand than for primary actions but more left‐handers did not use the right hand. That is, different frequencies of response to primary versus non‐primary actions were found for right‐handers but not for left‐handers. The pattern of findings was repeated for a corresponding analysis of left‐handed throwing × AHPQ actions. The findings have implications for the classification of hand preferences and for analyses of the nature of hand skill.     

The role of color in human face detection

Significant advances have been made in understanding human face recognition . However, a fundamental aspect of this process, how faces are located in our visual environment, is poorly understood and little studied. Here we examine the role of color in human face detection. We demonstrate that detection performance declines when color information is removed from faces, regardless of whether the surrounding scene context is rendered in color. Furthermore, faces rendered in unnatural colors are hard to detect, suggesting a role beyond simple segmentation. When faces are presented such that half the surface is colored appropriately, and half unnaturally, performance declines. This suggests that observers are not simply using the presence of skin color "patches" to detect faces. Rather, our data suggest that detection operates via a face template combining diagnostic color and face-shape information. These findings are consistent with color-template approaches used in some computer-based face detection systems.     

The role of animacy in spatial transformations

We present evidence that different mental spatial transformations are used to reason about three different types of items representing a spectrum of animacy: human bodies, nonhuman animals, and inanimate objects. Participants made two different judgments about rotated figures: handedness judgments (“Is this the left or right side?”) and matching judgments (“Are these figures the same?”). Perspective-taking strategies were most prevalent when participants made handedness judgments about human bodies and animals. In contrast, participants generally did not imagine changes in perspective to perform matching judgments. Such results suggest that high-level information about semantic categories, including information about a thing’s animacy, can influence how spatial representations are transformed when performing online problem solving.

Infant color preference for red is not selectively context specific

It has been proposed that human infants, like nonhuman primates, respond favorably to red in hospitable contexts, yet unfavorably in hostile contexts (Maier, Barchfeld, Elliot, & Pekrun, 2009). Here, we replicate and extend the study (Maier et al., 2009) whose findings have been used to support this hypothesis. As in Maier et al., 1-year-old infants were shown a photograph of a happy or angry face before pairs of colors were presented, yet in the current study, the set of stimuli crucially included two colors that are typically preferred by infants (red and blue). The percentage of times that infants looked first at the colors was analyzed for the two emotional "contexts." Following the happy face, infants looked first at red and blue equally, but significantly more than green. Following the angry face, the pattern of looking preference was the same as following the happy face, but the variation across the three colors was reduced. Contrary to Maier et al.'s hypothesis, there was no evidence that infants are selectively averse to red in angry contexts: following the angry face, "preference" for both red and blue was reduced, but was not significantly below chance. We therefore suggest an alternative account to Maier et al.'s evolutionary hypothesis, which argues that an angry face merely removes infant color preference, potentially due to the perceptual characteristics of the angry face disrupting infants' encoding of color.

Judgment is not color blind: The impact of automatic color preference on product and advertising preferences

This research examines the colors white and black and highlights the importance of automatic preference for the color white over black in product choice and advertising contexts. Across three studies, we incorporate multiple Implicit Association Tests to assess automatic preferences for colors, products, races, and advertisements. In Study 1, we demonstrate an automatic color preference for white over black, show that this preference holds for Caucasian-Americans and African-Americans, and find that automatic color preference predicts automatic product preference of white over black-colored products. Study 2 extends these findings by showing that actual behavioral product choice is best predicted by a combination of automatic and explicit color preferences. In the advertising domain, Study 3 demonstrates how automatic color preference influences advertising responses and how it explains the lack of in-group preference by African-Americans in previous implicit studies of racial preference. Collectively, our research draws attention to the need to disentangle white and black as designation of colors versus racial groups, and offers significant and novel contributions to the work on color and race in consumer psychology.     

The role of facial orientation in newborn infants’ preference for attractive faces

Several previous experiments have found that newborn and young infants will spend more time looking at attractive faces when these are shown paired with faces judged by adults to be unattractive. Two experimental conditions are described whose aim was to find whether the ‘attractiveness effect’ is affected by the orientation of the facial stimuli. Pairs of attractive and less attractive faces (as judged by adults) were shown to newborn infants (mean age 2 days 20.5 hours), where each pair was presented both upright and inverted through 180°. In the former (upright) condition, but not the latter (inverted) condition, the infants looked longer at the attractive faces, and the difference in attractiveness preference between the conditions was statistically significant. These findings are clear evidence that infants’ early representation of faces contains information about faces that is orientation‐specific. The results are discussed in terms of innate facial representations and rapid learning about faces in the hours from birth.
