Surface location and enclosure

This research addressed the issue of whether impressions of enclosure were more strongly influenced by amount of view covered by vertical boundaries (H1) or the presence of a boundary overhead (H2). There were three studies with totals of 48 stimuli and 142 respondents. Stimuli were balconies, swamps, and space stations. Effect sizes were reported for variables of boundaries below, in front of, and at the observers' sides, as well as amount of view covered by any boundary regardless of location with respect to the observer. Judged enclosure correlated at r =.80 for amount of view covered by vertical boundaries and r =.42 with the presence or absence of boundaries overhead, indicating that enclosure is more strongly related to vertical rather than overhead boundaries (alpha< .001).     

EFFECTS OF APPLICANT RACE, SEX, SUITABILITY, AND ANSWERS ON INTERVIEWER'S QUESTIONING STRATEGY AND RATINGS

Impression formation research (Snyder & Swann, 1978) suggests that people engage in information seeking strategies designed to confirm their impressions of others. In an extension of this work to the selection interview, Sackett (1982) found, however, that subjects did not consistently adopt a confirmatory information seeking strategy. This study is a further examination of Snyder and Swann's theory. In simulated interviews 170 subjects (1) read resumes of hypothetical applicants, (2) selected ten questions to ask each applicant, (3) received written responses to each question immediately on its selection, and (4) rated each applicant's suitability. An interaction accounting for 73% of variance indicated that applicant ratings were based primarily on the content of applicants' responses, but initial impressions also played a part. No clear-cut, confirmatory information seeking strategy was observed.     

Effect of an observer's presence on facial behavior during dyadic communication

In everyday life, people communicate not only with another person but also in front of other people. How do people behave during communication when observed by others? Effects of an observer (presence vs absence) and interpersonal relationship (friends vs strangers vs alone) on facial behavior were examined. Participants viewed film clips that elicited positive affect (film presentation) and discussed their impressions about the clips (conversation). Participants rated their subjective emotions and social motives. Durations of smiles, gazes, and utterances of each participant were coded. The presence of an observer did not affect facial behavior during the film presentation, but did affect gazes during conversation. Whereas the presence of an observer seemed to facilitate affiliation in pairs of strangers, communication between friends was exclusive and not affected by an observer.     

CHILDREN'S PERSON PERCEPTION: THE GENERALIZATION FROM TELEVISION PEOPLE TO REAL PEOPLE

This study investigated children's perceptions of television people and the extent to which these perceptions are generalized to impressions of peers. Elementary school children (W=172) completed questionnaires measuring viewing, knowledge of, identification with, and the perceived reality of television characters, and ratings of peers on 11 traits (e.g., funny, attractive, kind, nice). Two criterion variables were studied: children's mean rating of peers on each of the traits and the variance in the ratings of peers on each trait. Multiple regression analyses (controlling for grade and sex) revealed that: (1) identification with television characters was a significant predictor of the mean evaluation of peers on the traits; (2) television viewing was a significant predictor of the variance in children's ratings of peers; and (3) the relationship between television viewing and the variance in trait ratings was lower for attributes found in past studies to be suggested by television presentations. Implications of these findings for the traditional concern that television standardizes perceptions of people through stereotyping are considered.     

Social relevance enhances memory for impressions in older adults

Previous research has demonstrated that older adults have difficulty retrieving contextual material over items alone. Recent research suggests this deficit can be reduced by adding emotional context, allowing for the possibility that memory for social impressions may show less age-related decline than memory for other types of contextual information. Two studies investigated how orienting to social or self-relevant aspects of information contributed to the learning and retrieval of impressions in young and older adults. Participants encoded impressions of others in conditions varying in the use of self-reference (Experiment 1) and interpersonal meaningfulness (Experiment 2), and completed memory tasks requiring the retrieval of specific traits. For both experiments, age groups remembered similar numbers of impressions. In Experiment 1 using more self-relevant encoding contexts increased memory for impressions over orienting to stimuli in a non-social way, regardless of age. In Experiment 2 older adults had enhanced memory for impressions presented in an interpersonally meaningful relative to a personally irrelevant way, whereas young adults were unaffected by this manipulation. The results provide evidence that increasing social relevance ameliorates age differences in memory for impressions, and enhances older adults’ ability to successfully retrieve contextual information.

Judging a Book by Its Cover: The Differential Impact of Attractiveness on Predicting One's Acceptance to High‐ or Low‐Status Social Groups

Emerging research suggests that the cues we glean from first impressions depend on our goals. This research uses sorority recruitment to examine whether groups that vary in social status rely on disparate cues to form first impressions of potential new group members. Current sorority members were given 500 ms to view pictures of women who wanted to join their sororities, and were then asked how likely it was that each prospective member would receive a bid from their sorority (bid expectancy). Prospective members were also rated on their attractiveness. Data were analyzed separately for high‐ vs. low‐status houses. Results revealed that attractiveness was more predictive of liking and bid expectancy for the high‐status houses, as compared to the low‐status houses.     

The Pollyanna myth: how highly agreeable people judge positive and negative relational acts

Although people high in agreeableness have often been shown to be positively biased toward others, four studies provide evidence that agreeableness is associated with extremity effects, not simple positivity effects, in social judgment. Across studies, agreeable participants judged prosocial behaviors more favorably, but antisocial behaviors more unfavorably, than did disagreeable participants. In support of a goal-congruence mechanism, Study 1 showed that communal goals, rather than perceived similarity, mediated the effects, and Studies 2-4 demonstrated that agreeable perceivers were particularly sensitive to communal (vs. agentic) violations. A longitudinal study of real-life impressions supported the laboratory evidence that agreeable people are highly sensitive to both the prosocial and antisocial behavior of others (Study 4). We discuss how the current account complements and extends existing theories of agreeableness.     

How many hindsight biases are there?

The answer is three: questioning a conceptual default assumption in hindsight bias research, we argue that the hindsight bias is not a unitary phenomenon but consists of three separable and partially independent subphenomena or components, namely, memory distortions, impressions of foreseeability and impressions of necessity. Following a detailed conceptual analysis including a systematic survey of hindsight characterizations in the published literature, we investigated these hindsight components in the context of political elections. We present evidence from three empirical studies that impressions of foreseeability and memory distortions (1) show hindsight effects that typically differ in magnitude and sometimes even in direction, (2) are essentially uncorrelated, and (3) are differentially influenced by extraneous variables. A fourth study found similar dissociations between memory distortions and impressions of necessity. All four studies thus provide support for a separate components view of the hindsight bias. An important consequence of such a view is that apparent contradictions in research findings as well as in theoretical explanations (e.g., cognitive vs. social-motivational) might be alleviated by taking differences between components into account. We also suggest conditions under which the components diverge or converge.     

Multiple landmarks, the encoding of environmental geometry and the spatial logics of a dual brain

A series of place learning experiments was carried out in young chicks (Gallus gallus) in order to investigate how the geometry of a landmark array and that of a walled enclosure compete when disoriented animals could rely on both of them to re-orient towards the centre of the enclosure. A square-shaped array (four wooden sticks) was placed in the middle of a square-shaped enclosure, the two structures being concentric. Chicks were trained to ground-scratch to search for food hidden in the centre of the enclosure (and the array). To check for effects of array degradation, one, two, three or all landmarks were removed during test trials. Chicks concentrated their searching activity in the central area of the enclosure, but their accuracy was inversely contingent on the number of landmarks removed; moreover, the landmarks still present within the enclosure appeared to influence the shape of the searching patterns. The reduction in the number of landmarks affected the searching strategy of chicks, suggesting that they had focussed mainly on local cues when landmarks were present within the enclosure. When all the landmarks were removed, chicks searched over a larger area, suggesting an absolute encoding of distances from the local cues and less reliance on the relationships provided by the geometry of the enclosure. Under conditions of monocular vision, chicks tended to rely on different strategies to localize the centre on the basis of the eye (and thus the hemisphere) in use, the left hemisphere attending to details of the environment and the right hemisphere attending to the global shape.This contribution is part of the special issue “Animal Logics” (Watanabe and Huber 2006).     

The behavioral economics of production.

In two experiments, thirsty rats licked an empty spout instrumentally for water delivered at a neighboring spout. Each such pair of spouts constituted a work station, and one, two, or three stations were available in the test enclosure. In 1-hr sessions, the rats worked alone or in the company of 1 or 2 other rats, and performed either five, 10, or 40 licks at the empty spout for each water delivery. The total number of empty-spout licks, summed across rats and stations, increased with the empty-lick requirement and, with some exceptions, the number of rats in the enclosure and the number of work stations available. A Cobb-Douglas production function, with instrumental responding as an output and the three independent variables as inputs, accounted for a significant percentage of the variance. Contrary to that function, output failed to increase with additional rats (or work stations) when the number of work stations (or rats) was relatively small.     

Perceived causality and perceived force: Same or different?

Visually perceived interactions between objects, such as animated versions of billiard ball collisions, give rise to causal impressions, impressions that one object produces some effect in another, and force impressions, impressions that one object exerts a certain amount of force on another. In four experiments, evidence for strong divergence between these two impressions is reported. Manipulations of relative direction of motion and point of contact between the objects had different effects on the causal and force impressions (Experiment 1); delay between one object contacting another and the latter starting to move had a stronger effect on the causal impression than on the force impression (Experiment 2); a context of other moving objects significantly weakened the causal impression but not the force impression (Experiment 3); and there was an inverse relation between an impression of one object penetrating another and the amount of force the former was perceived as exerting on the latter (Experiment 4). These findings are explained in terms of differential effects of instructions on attention, and also in terms of differences in meaning between force and causality.     

An investigation of the diagnostic processing of contradictory information

In three parallel experiments, subjects rated their impressions of hypothetical 20-year-old males described by means of single or combined personality trait adjectives on 36 bipolar (Semantic Differential) scales. These ratings were a) intercorrelated across the scales (Q-technique) and factor analyzed separately for each subject, and b) submitted to an analysis of variance separately for each scale. It was shown that 1) when contradictory adjectives were combined the major portion of the variance of judgments fell on dimensions independent of that which characterized the contradiction; 2) there were substantial inter-individual consistencies in the direction of the deviation from that dimension; and 3) the utility of a linear model for the prediction of judgments of combined adjectives increases with increases in the extent to which the subject experiences the combination as consistent. However, the utility of the linear model decreases considerably and consistently if the combined adjectives are experienced as non-consistent.     

Representation of two geometric features of the environment in the domestic chick (<Emphasis Type="Italic">Gallus gallus</Emphasis>)

We report experiments based on a novel test in domestic chicks (Gallus gallus), designed to examine the encoding of two different geometric features of an enclosed environment: relative lengths of the walls and amplitude of the corners. Chicks were trained to search for a food reward located in one corner of a parallelogram-shaped enclosure. Between trials, chicks were passively disoriented and the enclosure was rotated, making reorientation possible only on the basis of the internal spatial structure of the enclosure. In order to reorient, chicks could rely on two sources of information: the relative lengths of the walls of the enclosure (associated to their left-right sense order) and the angles subtended by walls at corners. Chicks learned the task choosing equally often the reinforced corner and its rotational equivalent. Results of tests carried out in novel enclosures, the shapes of which were chosen ad hoc (1) to induce reorientation based only on the ratio of walls lengths plus sense (rectangular enclosure), or (2) to induce reorientation based only on corner angles (rhombus-shaped enclosure), suggested that chicks encoded both features of the environment. In a third test, in which chicks faced a conflict between these geometric features (mirror parallelogram-shaped enclosure), reorientation seemed to depend on the salience of corner angles. These results shed light on the elements of the environmental geometry which control spatial reorientation, and broaden the knowledge on the geometric representation of space in animals.     

FAVORABLE IMPRESSION CHARACTERISTICS OF THE RECRUITMENT INTERVIEWER

Students' impressions of campus recruiters influence students decisions on eventual job choice. In this study, the authors attempted to assess the effects of three variables—recruiter's age, recruiter's title, and recruiter's presentation—on students' impressions. A three factor factorial analysis of variance with three separate post hoc tests indicated that recruiter title and recruiter age significantly influenced impressions, while nonfluent presentation may have had a selective influence on impressions.     

Role of multiple resources in predicting time-sharing efficiency: evaluation of three workload models in a multiple-task setting

The goal of our study was to assess the validity of the assumptions underlying three prominent workload models: the Time-Line Analysis and Prediction workload model (Parks & Boucek, 1989), the VACP workload model (Aldrich, Szabo, & Bierbaum, 1989), and the W/INDEX model (North & Riley, 1989). Sixteen subjects flew a low-fidelity flight simulation. Subjects were required to perform a two-axis tracking task, a concurrent visual-monitoring task, and a discrete decision task. The decision task had 16 variations defined by two levels on each of the following dimensions: input modality (visual vs. auditory), processing code (spatial vs. verbal), difficulty (easy vs. hard), and response modality (manual vs. voice). Dual-task costs were found only for the tracking task. The tracking data were then analyzed using two approaches: a traditional analysis of variance (ANOVA) and a correlational analysis of tracking performance versus model predictions. The ANOVA revealed that performance on the tracking task was better when the concurrent decision task was responded to vocally and was easy. Input modality and processing code of the concurrent decision task had no significant effect on tracking performance. The correlational analysis was used to evaluate each of the three models, to determine what features were responsible for improving the models' fit, and to compare their performance with a pure time-line model that makes no multiple-resource assumptions. All three models did a good job of predicting variance between experimental conditions, accounting for between 56% and 84% of the variance in our data and between 10% and 40% of an earlier data set. Different features of each model that affect the fit are then discussed. We conclude that it is important for models to retain a multiple-resource coding, although the best features of that coding remain to be determined. Coding tasks by their demand level appears to be less critical.     

Effects of State Humor,Expectancies, and Choice on Postsurgical Mood and Self-Medication: A Field Experiment1

It was hypothesized that repeated exposure to humorous material reduces distress, pain, and medication following surgery. This hypothesis was tested in a field experiment by randomly assigning 78 postsurgical patients to either a control group or 1 of 8 experimental groups formed by the factorial crossing of type of videotape (humorous vs. serious), perceived control (choice vs. no choice), and expectation (positive vs. none). Multivariate analyses of variance disclosed that humor reduced requests for minor medication, combined with expectations to reduce pain, but increased use of heavy analgesic when patients were deprived of choice. Although more research needs to be done, the findings suggest that hospital patients benefit from humorous and distracting material when exposure is voluntary.     

He's a Laker; She's a “Looker”: The Consequences of Gender-Stereotypical Portrayals of Male and Female Athletes by the Print Media

Although an extensive qualitative literature shows that coverage of women's sport often focuses on female athletes' attractiveness (to the exclusion of their athleticism), there is a dearth of quantitative research examining exactly what effect this coverage has on people's perceptions of athletes. As part of a 2 (Gender of the Athlete: Female or Male) × 2 (Gender of the Participant: Female or Male) × 2 (Focus of the Article: Physical Attractiveness or Athleticism) between-subjects design, 92 predominantly White undergraduates (40 men, 52 women) read a fictitious newspaper profile about an Olympic athlete in which the article focused on the athlete's attractiveness (as coverage of female athletes often does) or on the athlete's athleticism (as coverage of male athletes often does). Interestingly, participants neither had favorable impressions of nor liked articles about female and male athletes when attractiveness was the main focus of an article. These findings suggest that the media should be cognizant of the harmful and erroneous impressions that can result from portraying athletes in terms of their personal attributes rather than their athletic accomplishments.     

Diminished weight loss and behavioral compliance during repeated diets in obese patients with type II diabetes.

Compared weight losses during first and second bouts of a very low calorie diet (VLCD) and examined whether decreased compliance might in part explain the decrease in weight loss during the second bout. Forty-five Type II diabetic patients participated in a year-long behavioral weight-reduction program that incorporated a VLCD (400 to 500 kcal/day) during Weeks 1 to 12 and 28 to 40. Weight losses decreased dramatically from the first to the second VLCD (15.54 vs. 1.42 kg, p less than .0001). There was also markedly diminished adherence as assessed by weeks ketonuric, attendance, and completeness of self-monitoring records. The percentage of weeks subjects were in ketosis dropped from 61% during VLCD 1 to 13% during VLCD 2 (p less than .0001). Similarly, subjects attended significantly fewer treatment meetings during VLCD 2 and self-monitored less during VLCD 2 than during VLCD 1. Weeks ketonuric and initial weight accounted for 63% of the variance in weight loss during VLCD 1 (p less than .0001); weeks ketonuric and attendance predicted weight loss during VLCD 2 (p less than .0001), accounting for 54% of the variance. These results suggest the importance of behavioral factors in explaining poorer performance on a repeated diet.     

品牌印象形成与改变的双重加工模型检验

为了探讨品牌印象的双重结构及其形成与改变的心理机制, 在双重加工模型理论基础上, 采用2×2×3完全随机被试间实验设计, 先后进行两个实验研究。结果显示：外显品牌印象的形成与改变遵循规则加工, 内隐品牌印象的形成与改变遵循联想加工, 说明二者是相互独立的两个心理结构, 为双重加工的双重系统观点提供了新证据。Smith和DeCoster (2000)的双重加工模型未考虑被试对信息的卷入程度对联想加工和规则加工的影响, 使其理论解释力不够, 此研究结果正好在这方面取得了进展。
