The effect of gaze on gaze direction while looking at art

In highly controlled cuing experiments, conspecific gaze direction has powerful effects on an observer’s attention. We explored the generality of this effect by using paintings in which the gaze direction of a key character had been carefully manipulated. Our observers looked at these paintings in one of three instructional states (neutral, social, or spatial) while we monitored their eye movements. Overt orienting was much less influenced by the critical gaze direction than what the cuing literature might suggest: An analysis of the direction of saccades following the first fixation of the critical gaze showed that observers were weakly biased to orient in the direction of the gaze. Over longer periods of viewing, however, this effect disappeared for all but the social condition. This restriction of gaze as an attentional cue to a social context is consistent with the idea that the evolution of gaze direction detection is rooted in social communication.

The gaze of the optimist

Two studies used eye tracking to investigate the attentional preferences of optimists and pessimists to negative emotional stimuli. In both studies, optimistic and pessimistic college students viewed three types of visual stimuli while having their eye movements tracked: skin cancer (melanoma) images, matched schematic line drawings, and neutral faces. In the first study, participants were asked to view the images naturally, whereas in the second study, some participants received a relevance manipulation. Percentage of fixation time to the different images was measured. Optimists showed selective inattention to the skin cancer images, even after controlling for attention to matched schematic line drawings. This relationship remained significant in both studies after controlling for the effects of neuroticism, affect, anxiety, relevance, and perceptual variables. These data suggest that optimists may indeed wear "rose-colored glasses" in their processing of information from the world.     

The effect of masked pictures on the interpretation of ambiguous pictures

Two experiments investigated whether the initial organization of ambiguous pictures presented supraliminally could be influenced by the presentation of semantically related pictures that had been pattern masked to prevent conscious representation. Twenty-two pictures were presented tachistoscopically in a counterbalanced sequence, each alternating with the supraliminal presentation of its ambiguous counterpart. The results supported the hypothesis that pictures precluded from consciousness by pattern masking could nevertheless influence the interpretation of ambiguous pictures. Although the possibility of structural priming could not be completely ruled out in these experiments, there is evidence to suggest that semantic priming is a component. The research potential of semantic priming is also discussed.     

The development of mentalistic gaze understanding

Very young infants are sensitive to and follow other people's gaze. By 18 months children, like chimpanzees, apparently represent the spatial relationship between viewer and object viewed: they can follow eye‐direction alone, and react appropriately if the other's gaze is blocked by occluding barriers. This paper assesses when children represent this relationship as psychological in nature. Studies examining sensitivity to gaze, gaze following, and explicit judgement of gaze direction are reviewed. The evidence suggests that neither infants nor chimpanzees represent gaze as psychological. It is concluded that mentalistic gaze understanding develops from the age of 3 years.

The malleability of age-related positive gaze preferences: training to change gaze and mood

Older adults show positive gaze preferences, but to what extent are these preferences malleable? Examining the plasticity of age-related gaze preferences may provide a window into their origins. We therefore designed an attentional training procedure to assess the degree to which we could shift gaze and gaze-related mood in both younger and older adults. Participants completed either a positive or negative dot-probe training. Before and after the attentional training, we obtained measures of fixations to negatively valenced images along with concurrent mood ratings. We found differential malleability of gaze and mood by age: for young adults, negative training resulted in fewer posttraining fixations to the most negative areas of the images, whereas positive training appeared more successful in changing older adults' fixation patterns. Young adults did not differ in their moods as a function of training, whereas older adults in the train negative group had the worst moods after training. Implications for the etiology of age-related positive gaze preferences are considered.     

The donor is in the details

Recent research finds that people respond more generously to individual victims described in detail than to equivalent statistical victims described in general terms. We propose that this “identified victim effect” is one manifestation of a more general phenomenon: a positive influence of tangible information on generosity. In three experiments, we find evidence for an “identified intervention effect”; providing tangible details about a charity’s interventions significantly increases donations to that charity. Although previous work described sympathy as the primary mediator between tangible information and giving, current mediational analyses show that the influence of tangible details can operate through donors’ perception that their contribution will have impact. Taken together with past work, the results suggest that tangible information of many types promotes generosity and can do so either via sympathy or via perceived impact. The ability of tangible information to increase impact points to new ways for charities to encourage generosity.     

The meaning of five patterns of gaze

Subjects had five encounters with trained confederates, who each displayed five patterns of gaze with different subjects, in a graeco-latin square design. The patterns of gaze were: Zero, looking while talking, looking while listening, normal and continuous. Two conditions were used: Subjects were either getting acquainted with the confederates or assessing them while they behaved in an ingratiating manner. Subjects and confederates were either both male or both female. Subjects rated the confederates on fifteen rating scales; a principle components analysis produced five main components, the first two being liking/evaluation and activity/potency. Gaze affected scores on these components as predicted: Ratings of liking/evaluation increased from zero gaze to normal and were lower for continuous — confirming the affiliative balance theory; and the more gaze the higher the ratings on activity/potency. The predicted effects of ingratiation on the interpretation of gaze were not obtained, though ingratiators were seen as less intelligent. Decoders responded to amount of gaze, and not to its relation to talking and listening.     

Peck tracking: a method for localizing critical features within complex pictures for pigeons

The pigeon is a standard animal in comparative psychology and is frequently used to investigate visuocognitive functions. Nonetheless, the strategies that pigeons use to discriminate complex visual stimuli remain a difficult area of study. In search of a reliable method to identify features that control the discrimination behaviour, pecking location was tracked using touch screen technology in a people-absent/people-present discrimination task. The correct stimuli contained human figures anywhere on the picture, but the birds were not required to peck on that part. However, the stimuli were designed in a way that only the human figures contained distinguishing information. All pigeons focused their pecks on a subarea of the distinctive human figures, namely the heads. Removal of the heads significantly impaired performance, while removal of other distinctive parts did not. Thus, peck tracking reveals the location within a complex visual stimulus that controls discrimination behaviour, and might be a valuable tool to reveal the strategies pigeons apply in visual discrimination tasks.     

The effect of informative events on response rate

A single group of pigeons received two different training conditions presented on different response keys. Responding during the first component of each condition was reinforced, according to a fixed interval schedule, by gaining access to the second component. In the uninformative condition the second component consisted on every trial of the illumination of the response key for 10 sec, the key was then darkened and food presented with a probability of 0.5. In the informative condition half of the trials at the conclusion of the first component resulted in the key being darkened and no additional events were presented. On the remaining trials the second component was similar to that for the uninformative condition. The results from the first two stages revealed that responding during the first component was faster in the informative than uninformative condition when trials were presented separately. In the final stage, when the trials were presented simultaneously, the rate of responding during the first component was eventually similar in the two conditions, but subjects preferred the second component of the informative condition. These results suggest that events which are informative, or perhaps unpredictable, can support a higher response rate than those which are uninformative, or predictable.     

The perception of semantic relations in pictures

Three picture processing experiments are reported that present evidence of an “agent advantage effect,” that is, faster processing of the performer of the action depicted the agent of the action than of the element acted upon (the patient). Experiment 1 demonstrated the effect in a paradigm in which reaction time to manually indicate the location of a target (agent or patient) was faster for agent targets. Experiment 2 demonstrated that the critical time required for subjects to encode the agent was shorter than the time required for encoding patients. Experiment 3 again demonstrated the agent advantage effect in a directed attention paradigm. Together, the results of the experiments indicated that subjects were able to encode agent information faster than patient information. The results also indicated that subjects did not adopt a strategy whereby encoding of patient information was necessarily dependent upon encoding agent information.
