Competitiveness and the Similarity of Preferred Coworkers1

The study investigated effects of different work contexts on the individual's desire to work with a similar or dissimilar coworker. Business students (N= 536) were assigned to 1 of 3 conditions (competitive task, skill‐development task, and nonspecific task) and were asked to describe their preferred coworker for that task. Individuals were expected to prefer coworkers whom they perceived as similar in noncompetitive situations, but those whom they perceived as dissimilar in competitive situations. Further, it was hypothesized that the type of similarity emphasized (skills, personal values, and personal style) would reflect the type of anticipated interaction. As expected, participants in competitive conditions chose coworkers with lower skills and generally dissimilar values and personal style. Coworkers selected for the skill‐development condition possessed similar skills and were more similar in values.     

Effects of felt adequacy and opportunity to reciprocate on help seeking

This experiment was prompted by the belief that felt inadequacy and lack of opportunity to reciprocate act as deterrents to help seeking when help is needed. The experiment was conducted on 56 freshmen by modifying Greenberg and Shapiro's physical disability paradigm. Subjects were told that they could not meet the quota on a manual task but had done well (poorly) for persons similarly handicapped (by arm in sling). Later they learned that the electricity would be shut off in 2 hr (15 min), making it possible (impossible) to help the visually handicapped fellow worker later on a visual task. The hypothesis that felt inadequacy inhibits help seeking was fully supported, while the corresponding hypothesis regarding lack of opportunity to reciprocate received only partial support. There were no sex differences. The relevance of these data for embarrassment theory is discussed.     

Level of instigation and model similarity as determinants of aggressive behavior

A study was conducted to replicate and extend a finding by Wheeler and Levine [1967] indicating that a dissimilar model was more effective in inducing the contagion of aggression than a similar model. On the basis of recent findings suggesting the circumstances under which dissimilar others are more influential than similar others, the following predictions were derived: When subjects are highly instigated, dissimilar models can influence subjects to be more aggressive than can similar models; when subjects are under a low degree of instigation similar models will influence subjects to be more aggressive. Subjects presented their point of view on a case study in a three-person group discussion setting. Then subjects heard the second person (instigator) attack their position in a highly abusive or slightly abusive manner (High vs Low Instigation). Next subjects heard a third person, whom they had been led to believe was similar or dissimilar to themselves, attack the instigator (Similar vs Dissimilar Model). Finally subjects had an opportunity to express their feelings to the instigator. The results supported the predictions.     

实物形状的知觉相似性对视觉隐喻加工的影响

视觉隐喻是众多研究者比较关注的领域, 当前多以物体简笔画、漫画及广告等方面的研究为主, 但对与生活密切相关的实物的视觉隐喻研究甚少。因此研究采用掩蔽启动范式、李克特9点量表及语音生成等研究方法, 在物体概念类型(概念相同、概念相异)及形状类型(形状相似、形状相异)条件下, 针对实物图片的形状知觉相似性是否对视觉隐喻加工产生影响进行探讨。结果发现无论物体概念是否相同, 形状相似性对个体的物体识别具有“促进”作用, 并有利于视觉隐喻加工; 在物体识别中, 当两个物体概念不同时, 个体会试图建立一个特设类别来对形状相似的物体进行归类, 从而实现了视觉隐喻的加工。因此研究进一步证明了实物形状的知觉相似性有利于视觉隐喻的加工。     

Mechanisms used by young children in the making of empathic judgments

Forty-four preschool children ranging from three to five years of age received a series of stones in which the protagonists experience happiness, sadness, or fear These protagonists were portrayed as either similar or dissimilar to the child, and the situations depicted were either familiar or unfamiliar to him/her as well The children's task was to infer the emotions experienced by the protagonists Results indicate that children were more accurate in judging the emotions of similar target persons than they were for dissimilar ones Familiarity with the situation, on the other hand, had no effect on accuracy Children were more accurate in identifying happiness and sadness than they were in judging fear, and age was positively related to judgmental accuracy for the former two but not for the latter These results help to resolve the controversy arising from earlier studies of empathy development which failed to disentangle the similarity and familiarity dimensions     

Opportunity for thought as a mediator of attraction to a dissimilar stranger: A further test of an information seeking interpretation

It has previously been shown that confusion, produced by an ambiguous film, leads to increased attraction to attitudinally dissimilar others. It was posited that confusion leads to a search for information that will help to structure the confusing situation, and that dissimilar others have perspectives that are of value in this regard. In the present study, subjects were exposed to either a confusing film, a nonconfusing film preceded by an explanation designed to produce confusion, or the nonconfusing film with no preceding explanation. They then were either given an opportunity to think about the film's meaning or were deprived of this opportunity through a filler task. It was argued that the opportunity to think about the film would allow subjects to gain structure, and that this would reduce their confusion, decrease their need for more information, and thereby decrease their attraction to a dissimilar other. The results supported this contention. That is, subjects exposed to either the confusing film or the nonconfusing film with an explanation and then given an opportunity for thought showed significantly less attraction to a dissimilar stranger than their counterparts who were deprived of this opportunity.

Determinants of help seeking behaviour: The effects of helper's similarity,task centrality and recipient's self esteem

The present experiment was concerned with the way in which the characteristics of the helper the task and the recipient affect the willingness to seek help. In line with past theory and research it was reasoned that seeking help would be most threatening when one needs help on an ego - central task, and the helper is perceived as similar to oneself. Consequently, individuals were expected to seek least help under these conditions. Further it was expected that individuals who enjoy a high self esteem would be more sensitive to this self threat and seek less help under these self threatening conditions than would individuals who have a low self esteem. The experiment consisted of a 2 (similar versus dissimilar helper) times 2 (ego-central versus non central task) times 2 (high versus low self esteem subjects) between subjects design. Subjects worked on a difficult anagram task, and their actual help seeking behaviour served as a dependent measure. The findings support the experimental hypotheses. The conceptual and applied implications of these findings are discussed.     

Choice-induced preferences in the absence of choice: Evidence from a blind two choice paradigm with young children and capuchin monkeys

In two studies, we provide a test of the revealed-preferences account of choice-induced preferences. To do so, we introduce a blind two-choice task in which preferences cannot guide choices. Children chose between two similar objects while ignorant of the objects’ identities, and then chose between the rejected alternative and a third similar object. Monkeys were given an illusion of choice between two similar objects, and then chose between the rejected object and a third similar object. Both children and monkeys preferred the third object, indicating that they devalued the rejected object. This response pattern did not occur when the children and monkeys were not given the opportunity to choose between the two initial items. These results provide evidence against a revealed-preferences account of choice-induced preferences and demonstrate that the process of making a choice itself induces preferences.     

Perceptual learning in face processing: Comparison facilitates face recognition

Theoretical analyses of perceptual learning suggest that comparison between similar stimuli aids subsequent discrimination between them. The current studies examined whether the opportunity to compare a target face to other similar faces during a preexposure phase facilitated performance on a matching task. Performance was better when the target face had been presented in alternation with similar comparator faces than if that target had not been exposed before test. Exposure to the target face without comparators, or exposure alternating with dissimilar faces, improved performance relative to the nonexposed control but performance was not as good as when target exposure was given in alternation to similar comparison faces. The effects were not influenced by image changes between exposure and test. It is suggested that exposure to a face in comparison to similar stimuli focuses the central representation of a face on its unique features. In practical terms these results suggest that reliable identification of an individual from their photograph would be improved by viewing that photograph in comparison with photographs of similar people.     

The use of visual and name codes in scanning and classifying colors

The effect of incongruent color words on speed of classifying ink colors was measured in visual scanning tasks and in card sorting tasks. In both cases, little or no interference effects were noted when the classification allowed focusing on a single ink color or a set of highly similar colors (adjacent hues). Substantial interference occurred when the task required grouping of three dissimilar colors (nonadjacent hues). These findings suggest that the relative efficiency of name and visual codes in making perceptual classifications is largely dependent upon the memory requirements imposed by the task.     

Implicit identification of irrelevant local objects interacts with global/local processing of hierarchical stimuli

This work aimed at studying interactions between automatic object identification and global/local perceptual processing. We designed a paradigm in which participants were presented with pairs of hierarchically organized items, composed of global forms made up of local forms. Both global and local forms could represent either objects or non-objects. Subjects were instructed to detect whether the two hierarchical items composing a pair were identical or different. In a dissimilar pair, items differed at one level (target level), the other level, made of similar forms on both sides, was irrelevant to perform the task. We hypothesized that the automatic identification of object could affect the global precedence principle defined by Navon. In agreement with our hypothesis, we found that when the irrelevant level was made of objects, the global precedence effect was reversed. In contrast, the irrelevant level had no effect when the target level included only objects, or when the irrelevant level was made of non-object, the global precedence principle was being preserved in these cases. This interaction is compatible with the existence of two distinct processes working in parallel, namely automatic identification and structural analysis, that could either interfere or act together for the detection of differences.     

Receiving Help,Reciprocation, and Interpersonal Attraction1

In a 3 × 3 factorial experiment with 3 additional cells, 329 male or female subjects working with two same-sex confederates (A and B), received either voluntary, involuntary, or no help from A after which attraction to A and B were measured for one-fourth of the subjects. The remaining subjects were assigned to a second set of tasks and were induced to help A, help B, or were not given an opportunity to help, after which they completed attraction and mood measures. Subjects were more likely to volunteer help after the second task when they had received prior help. Receipt of help led to more liking for the helper and the helper was liked more when subjects were able to reciprocate. Attraction and mood results are discussed in relation to attractiveness mediation, modeling, and indebtedness explanations for reciprocity.     

Competition between memory and perceptual tasks involving physically similar stimuli

Performance on a perceptual recognition task and a concurrently performed short-term memory (STM) task was studied. The stimuli used in the STM task were either visually similar, acoustically similar, or dissimilar to the stimuli in the perceptual task. The results demonstrated that any type of concurrent list memorization has a detrimental effect upon perceptual performance, but this effect is magnified if the stimuli used in the 2 tasks are visually similar. Acoustic similarity had no effect. The results document the fact that distinct tasks interfere, when the tasks compete for a limited total processing capacity, or when the tasks demand the same visual coding program.     

Gender differences in memory for objects and their locations: a study on automatic versus controlled encoding and retrieval contexts

Object-location memory is the only spatial task where female subjects have been shown to outperform males. This result is not consistent across all studies, and may be due to the combination of the multi-component structure of object location memory with the conditions under which different studies were done. Possible gender differences in object location memory and its component object identity memory were assessed in the present study. In order to disentangle these two components, an object location memory task (in which objects had to be relocated in daily environments), and a separate object identity recognition task were carried out. This study also focused on the conditions under which object locations were encoded and retrieved. Only half of the participants were aware of the fact that object locations had to be retrieved later on. Moreover, by applying the 'process dissociation procedure' to the object location memory assessments and the 'remember-know' paradigm to the object identity measure, the amount of explicit (conscious) and implicit (unconscious) retrieval was estimated for each component. In general, females performed better than males on the object location memory task. However, when controlled for object identity memory, females no longer outperformed males, whereas they did not obtain a higher general object identity memory score, nor did they have more explicit or implicit recollection of the object identities. These complicated effects might stem from a difference between males and females, in the way locations or associations between objects and locations are retrieved. In general, participants had more explicit (conscious) recollection than implicit (unconscious) recollection. No effect of encoding context was found, nor any interaction effect of gender, encoding and retrieval context.     

The effects of similarity of theme and instantiation in analogical reasoning.

The influence of 2 types of structural similarity on analogical reasoning was examined. The theme of a story is a structural component that constrains other relationships in the story. Another structural component is the way in which the theme is implemented. Participants received pairs of stories that varied in the similarity of these two components. Participants in Experiment 1 judged stories containing similar themes as more analogous than stories with dissimilar themes. Likewise, stories with similar implementations were judged as more analogous than stories with dissimilar implementations. Experiment 2 revealed a similar pattern when participants had the opportunity to transfer information from source to target stories. Greater transfer was seen for stories with similar themes than for stories with dissimilar themes. Greater transfer was also seen for stories with similar implementations of different themes than for stories with different implementations.     

Similarity of attitudes and instrumentality as determinants of aggression by policemen

The influences of two determinants of aggression were investigated by means of a two by two factorial design. Aggression was operationally defined in terms of the amount and intensity of obnoxious sounds which the subject delivered to the confederate while the latter was trying to perform a task involving estimation of distances. In order to manipulate the first independent variable one half of the group of subjects were led to believe that the victim was someone who had many attitudes similar to their own. The other subjects thought they had to cope with a partner whose attitudes were dissimilar. The second independent variable was manipulated by suggesting to one half of the group of subjects that they would be able to earn increasing sums of money (up to a fixed maximum) depending on the loudness of sounds they were prepared to deliver to their partner. In the non-reward condition money was not mentioned. The subjects were young policemen. The data showed a strong effect of the similarity variable, with significantly more aggression being shown to a dissimilar partner. However, external reward did not lead to a clear increase of aggression. In the discussion attention is given to the relevance of these data to the problem of control of violence in our society.     

Measuring the influence of similarity on category-specific effects

There is evidence for both advantages and disadvantages in normal recognition of living over nonliving things. This paradox has been attributed to high levels of perceptual similarity within living categories having a different effect on performance in different contexts. However, since living things are intrinsically more similar to each other, previous studies could not determine whether the various category effects were due to perceptual similarity, or to other characteristics of living things. We used novel animal and vehicle stimuli that were matched for similarity to measure the influence of perceptual similarity in different contexts. We found that displaying highly similar objects in blocked sets reduced their perceived similarity, eliminating the detrimental effect on naming performance. Experiment 1 demonstrated a disadvantage for highly similar objects in name learning and name verification using mixed groups of similar and dissimilar animals and vehicles. Experiment 2 demonstrated no disadvantage for the same highly similar objects when they were blocked, e.g., similar animals presented alone. Thus, perceptual similarity, rather than other characteristics particular to living things, is affected by context, and could create apparent category effects under certain testing conditions.     

Visual awareness of objects and their colour

At any given moment, our awareness of what we 'see' before us seems to be rather limited. If, for instance, a display containing multiple objects is shown (red or green disks), when one object is suddenly covered at random, observers are often little better than chance in reporting about its colour (Wolfe, Reinecke, & Brawn, Visual Cognition, 14, 749-780, 2006). We tested whether, when object attributes (such as colour) are unknown, observers still retain any knowledge of the presence of that object at a display location. Experiments 1-3 involved a task requiring two-alternative (yes/no) responses about the presence or absence of a colour-defined object at a probed location. On this task, if participants knew about the presence of an object at a location, responses indicated that they also knew about its colour. A fourth experiment presented the same displays but required a three-alternative response. This task did result in a data pattern consistent with participants' knowing more about the locations of objects within a display than about their individual colours. However, this location advantage, while highly significant, was rather small in magnitude. Results are compared with those of Huang (Journal of Vision, 10(10, Art. 24), 1-17, 2010), who also reported an advantage for object locations, but under quite different task conditions.
