Defining Discrimination in the Personal/Group Discrimination Discrepancy

Members of low-status groups typically report that their group experiences more discrimination than they do personally, a phenomenon referred to as the personal/group discrimination discrepancy. It is hypothesized that manipulating the meaning of discrimination affects the personal/group discrimination discrepancy. In three studies, 301 female undergraduates (259 Whites; 42 non-Whites) from a large midwestern university read vignettes depicting discriminatory events that varied according to severity and frequency. Participants in high-frequency conditions perceived both more personal and group discrimination than low-frequency participants, and they showed smaller personal/group discrepancies. This effect was found for work-related discrimination and social sexism. Results indicate that severe and infrequent events are what people typically think of as discrimination and that using the term discrimination affects personal and group judgments. The importance of defining discrimination when investigating the personal/group discrimination discrepancy is discussed.     

Landmark Discrimination Learning in the Dog

Allocentric spatial memory was studied in dogs of varying ages and sources using a landmark discrimination task. The primary goal of this study was to develop a protocol to test landmark discrimination learning in the dog. Using a modified version of a landmark test developed for use in monkeys, we successfully trained dogs to make a spatial discrimination on the basis of the position of a visual landmark relative to two identical discriminanda. Task performance decreased, however, as the distance between the landmark and the “discriminandum” was increased. A subgroup of these dogs was also tested on a delayed nonmatching to position spatial memory task (DNMP), which relies on egocentric spatial cues. These findings suggest that dogs can acquire both allocentric and egocentric spatial tasks. These data provide a useful tool for evaluating the ability of canines to use allocentric cues in spatial learning.     

Sex Discrimination in Insurance

ABSTRACT The public controversy over sex-based differentials in insurance pricing makes heavy use of terms like 'fairness' and 'discrimination'; in particular, both sides argue that their position is the one dictated by considerations of fairness. Appeal to a basic principle of distributive justice shows that these differentials are not fair. Nevertheless, there is a substantial ethical argument to be made for the industry's status quo , based on the liberty of the low-risk insurees. The paper considers an alternative reform proposal, with a qualitatively different freedom cost; seven factors are then identified as useful in evaluating the trade-off between the freedom and justice at stake in any questionable insurance classification variable. A brief concluding section attempts to generalise this analysis to provide a broad framework for the analysis of other discrimination issues.     

Discrimination Learning and Discrimination Reversal Learning in Normal and Feebleminded Children

Two studies compared methods of estimating factor scores for the Child's Report of Parental Behavior Inventory. In Study I, least squares factor scores for 5th and 6th graders were computed and correlated with estimates obtained by multiple regression, weighted summation, and unweighted summation with either (a) all scales best defining each factor, (b) the three best, or (c) the two best defining scales. All three estimation methods were highly accurate, and estimates obtained with three and even two scales per factor still correlated highly with the factor scores. In Study 11, factor scores for college students were correlated with estimates obtained by multiple regression and unweighted summation of the same subsets of scales. Again both estimation methods were highly accurate, and reducing the number of scales did not markedly reduce the correspondence of estimated scores to exact scores.     

Discrimination between reinforced action patterns in the rat

Laboratory rats were rewarded for face-washing, rearing, or scratching by being given the opportunity to press retractable levers for food reward. Yoked control animals received the same number of lever presentations and food rewards, but did not have to face-wash, rear, or scratch to obtain the levers. The experimental animals showed increases in number of bouts of reinforced target behavior above control levels, and the total amount of time spent face-washing increased when a 1.5-sec criterion for reinforced bout length was introduced. The activities in this experiment were made to serve a discriminative as well as an instrumental function, since the cue to tell the rat which lever to press for reward when the levers were presented was the activity that the rat had engaged in to obtain lever presentation. In two separate experiments high levels of discrimination between behaviors were obtained. Discrimination was worse following scratching than after other actions, and scratching also showed relatively poor instrumental conditioning. The relationship between Pavlovian and instrumental conditioning processes in this situation is discussed.     

Age Discrimination in the Evaluation of Job Applicants

This study investigated the nature of age discrimination against older job applicants. One hundred fifty‐six participants (102 students; 54 organization based) evaluated a hypothetical job applicant's (aged 33–66 years) work‐related competences and likelihood of being hired. Applicant age affected hiring decisions for both samples where there was a preference for hiring applicants aged 42–48 years. Applicants at both the older and younger ends of the continuum were less likely to be hired, with the oldest applicants (over 54 years) being the least likely to be hired. Although the applicants' age negatively affected evaluations of their trainability and sociability, the effect of applicant age on hiring evaluations was not mediated by these work‐related competencies, suggesting that age discrimination occurs via direct bias against older workers.     

Conditional Reactions in the Rat

To assess the effects of the presence of the experimenter (E) and/or modelrewarder (MR), elementary school children observed a model emit specific sequences on a button pressing task in two separate experiments (N = 50 and N = 80). The first design was a 2 × 2 factorial involving the presence-absence of the E/MR and model reward vs. model no-consequences; the second design was a 4 × 2 factorial with all possible combinations of presence-absence of the E and/or MR, and model reward vs. model no-consequences. It was found that model reward increased imitation only in the condition in which the E was present and the MR was absent.     

Depth of Transference in Groups

An ongoing controversy in the field of group psychotherapy is whether transference regression is greater in groups than in individual treatment. There appears to be a general consensus that group behavior may be understood as operating on at least three levels—the conscious–rational, the oedipally determined transference, and the preoedipal maternal transference level. The more rational levels are associated with transference dilution, whereas the more primitive levels accompany transference intensification. Dilution occurs as a result of reality demands and inputs of the group situation and because of multiple targets of displacement. Transference intensification is a product of mutual stimulation, contagion effect, frustrating inputs, and support of the group theme. Certain patients benefit most from the dilution features of a group, and others profit most from intensification. The therapist's technique and the patient's pathology are the main determinants of which aspect gets emphasized and utilized.     

Depth adjacency in simultaneous contrast

The Gelb phenomenon, as an example of whiteness contrast, was investigated with three amounts of separation in depth between the test and induction disc. The cue of binocular disparity was used to vary the perceived depth between the discs. It was found that the magnitude of the contrast effect decreased with an increase in the perceived depth between the two discs. This change was regarded as an instance of the adjacency principle. The problem of whether the binocular disparity cue per se or perceived depth was the significant variable was discussed. The consequences of the results were considered with respect to the relation between whiteness constancy and whiteness contrast and the problem of neural localization of the contrast effect.

Depth perception by the active observer

The connection between perception and action has classically been studied in one direction only: the effect of perception on subsequent action. Although our actions can modify our perceptions externally, by modifying the world or our view of it, it has recently become clear that even without this external feedback the preparation and execution of a variety of motor actions can have an effect on three-dimensional perceptual processes. Here, we review the ways in which an observer's motor actions--locomotion, head and eye movements, and object manipulation--affect his or her perception and representation of three-dimensional objects and space. Allowing observers to act can drastically change the way they perceive the third dimension, as well as how scientists view depth perception.
