Dependency and fault as determinants of helping

In a natural setting, helping was investigated as a function of a female requestor's dependency on the subject for help and whether or not she was at fault for her plight. Based on previous research and the hypothesized operation of two norms, it was predicted that the negligent requestor would be more likely to receive help than the victim of circumstance when her dependency was high, but would be less likely to receive help when her dependency was low. Randomly selected telephone subscribers received a “wrong number” telephone call from a stranded women motorist. The woman asked the subject to make a phone call for her; the dependent variable was whether the subject helped by making the call. Results were consistent with predictions. When dependency is high, the victim's negligence appears to operate as an indication of greater need, whereas when dependency is low, it seems to operate as a sign that the victim is less deserving of help. Results were discussed in relation to different social norms that may be activated as a function of the dependency of the requestor.     

Probe similarity and recognition of set membership: A parallel-processing serial-feature-matching model

A model for memory scanning is proposed in which the encoded representation of a probe is compared in parallel with encoded representations of each item in the positive set. The within item matches are serial feature by feature comparisons that terminate when either a positive or negative criterion is reached. This model is shown to predict the results of a probe similarity experiment. The serial location of a similarity within an item affects negative reaction times, but the number of items in the positive set to which the probe is similar has no main effect. The model is also shown to yield predictions consonant with existing data on the relation between reaction times and set size and speed-accuracy trade offs.     

A sociolinguistic approach to the belief-similarity model of racial attitudes

This study examined the belief-similarity model of prejudice from a sociolinguistic perspective. It was hypothesized that normatively regulated speech styles strongly affect observers' assumptions about the cultural background of the speaker. These linguistically based cultural assumptions were expected to override racial characteristics in controlling intergroup attitudes. Stimulus speech styles were Black English Vernacular (BEV) and Standard English (SE). Speech style was expected to strongly affect prejudicial attitudes, with such effects mediated by assumed cultural similarity. Racial label and speech style were expected to be most salient to ratings of “intimate” behavior and among more ethnocentric subjects. Subjects heard taped statements in either BEV or SE, ostensibly delivered by a White or a Black speaker. Subjects rated the speaker on perceived cultural similarity, general evaluation, perceived aggressiveness, and social distance. Speech style had a substantial main effect on each of these variables. Racial label had a marginally significant effect on evaluation, and interacted with ethnocentrism for perceived similarity and social distance. All effects of speech, race, and ethnocentrism were substantially attenuated or eliminated when similarity was used as a covariate. Thus, speech style had substantial effects on prejudice, as did race within more ethnocentric subjects. Both effects were largely mediated by assumed cultural similarity.     

The use of categorial organization: Not an all-or-none situation

Second and fifth graders memorized each of two lists of words that differed in category representativeness. In addition, they received one of three memory instructions: standard free recall, repetition, or categorial processing. Recall performance was about equal for standard vs repetition, and both were lower than category processing, especially with the highly representative items. Age did not enter this interaction, so it is concluded that at both age levels, the accessibility of categorial information influences children's use of it. This suggests multiple types of possible production deficiencies.     

Social influence on attitudes and on anchoring of congeneric attitude scales

Criteria for distinguishing between attitude and response scale effects in “after-only” studies of source-recipient discrepancy were developed and applied in two experiments. These criteria refer to congeneric scales (i.e., multiple measures of the the same property, which may differ in origin, unit, and reliability). Persuasive information may function as a scale anchor, in which case it is expected to affect only that response scale to which it directly pertains. Alternatively, it may convice recipients to change attitudinal positions, and produce effects on all congeneric scales. In one experiment, the self-proclaimed leniency-sternness of a presiding judge in a manslaughter case was varied along with the sentence he imposed and his trustworthiness. In the second study, only the sentence was manipulated, while both leniency ratings and sentencing were measured as dependent variables. Both analyses revealed support for the response scale interpretation, in that effects were observed only on those scales that were directly manipulated.     

What's in a face: Individual differences in face perception

White and black females judged the similarity of all pairs of white and black male faces. An individual difference multidimensional scaling analysis of the similarity judgments indicated that most of the dimensions underlying the perceptions of male faces involved affective (honest, tense, attractive) characteristics rather than simple physical features (eye width, mouth height). The major physical dimension was face shape (long vs. wide). The dimensions were similar for black and white subjects. An individual difference hypothesis that we pay attention to those characteristics that we possess was partially confirmed.     

Uncertainty and social comparison

Two experimetnal tests were conducted of a model which predicts social comparison choices of extreme scores on a personality inventory. In groups of nine, subjects completed a bogus personality inventory that ostensibly measured a desirable or undesirable trait, and were told that either the highest or the lowest obtained score was a positive instance of the trait. The highest score was located for the subjects either with certainty or uncertainty, and the two experiments employed different manipulations of this factor. In both experiments the pattern of subjects' social comparison choices of other subjects' scores was fit best by a model comprising main effects of each factor and interactions between desirability and positive instance and between desirability and certainty.     

A stochastic model for paired comparisons of social stimuli

A stochastic model for paired comparisons of multiattribute social stimuli is proposed where one objective is to find the relative importance of the attributes for a judge. The model can be conceived as a special strict binary utility model, i.e., a BTL-model, and is related to of the stimuli are linear combinations of functions of the attributes of the stimuli. The model neither assumes that the functions are fixed in advance nor that different judges have the same set of functions. The choice among such functions, however, is admitted only within a finite scope. Within the framework of exponential families, maximum likelihood estimators and tests are derived and applied to data coming from two psychological experiments.     

Evidence for direct visual access to letter identities

Subjects were presented with two letters from the set BCDFGHLNPORTVZ, one in upper case and one in lower case. Subjects were required to decide, as quickly as possible, whether the two letters on each trial were the same (e.g., Bb) or different (e.g., Bd). Because letters were always physically different, subjects presumably must name the letters in order to respond. Reaction times were predicted by the visual similarity of the letters, and not by their phonemic distinctive feature similarity. Consistent with previous work showing that a word's meaning can be assessed directly from visual information, the findings suggest that visual analysis of a capital or small letter can result in knowing the latter name without further linguistic processing. These results were interpreted as an example of automatic detection as described by Schneider and Shiffrin (1977).     

Sources of visual field interference in children and adults

Subjects at three grade levels, third, sixth, and college (8, 11, and 20 years of age, respectively), were asked to identify briefly presented words accompanied by either words or letter strings in the same or opposite hemifield. Results indicated two sources of visual field interference, one relating to the presence of alphanumeric information elsewhere in the visual field and the second concerning the meaningfulness (lexical identity) of that information. The former showed a decrease in importance with age, and the latter an increase. Results were discussed in terms of the development of selective attention and hemispheric interaction.     

Training cooperation in the Prisoner's Dilemma

Female Ss' choices in two types of mixed-motive game situations were used to select Ss who had predominantly Own Gain and Ss who had predominantly Relative Gain goals. On the basis of simple reward notions, it was predicted that the former but not the latter would change from competitive to cooperative responding in decomposed Prisoner's Dilemma game situations when interacting with a conditionally cooperative other. Corresponding yoked controls were not expected to become cooperative. The availability of social comparison with an outcome which was smaller than the mutually cooperative outcome but larger than the mutually competitive out-come was expected to lead Own Gain Ss to more rapid learning of cooperation but not to affect the responses of corresponding yoked controls or of Relative Gain Ss. A 2 × 2 × 2 × 5 factorial design was used in which the factors were goal orientation (Own Gain vs Relative Gain), strategy of the other (conditionally cooperative vs yoked control), the availability vs unavailability of the social comparison, and trials. The results strongly supported each of the expectations. The results were discussed in terms of how the operation of the reward mechanism would be affected by the operation of some other social psychological processes.     

A hierarchy of information sources for inferring emotional reactions

The ability of children and adults to infer emotional reactions from different sources of information was investigated. Preschoolers (mean age, 4–9), second graders (mean age, 4–9), and college students were asked to infer emotional reactions from verbally presented stories in which sources of information occurred either singly, in conflict, or in congruence. The sources investigated were situational (the protagonist's social or physical situation), normative (the dispositions of a group to which the protagonist belongs), and personal (the dispositions of the protagonist in particular). Subjects indicated the protagonist's emotional reaction to an event in the story by choosing one of three facial expressions, representing happy, upset, and afraid. A hierarchy of sources for making emotional inferences was found at all three grade levels: personal information was preferred over normative information, and both were dominant over situational information. The relevance of present methods and findings to the study of the development of “empathy” is discussed.     

Self-punitive behavior with changing percentages of reinforcement: The proper role of discrimination

Past research on self-punitive behavior has been interpreted as supporting a theoretical éxplanation based on a vicious circle rather than a discrimination hypothesis. Using rats, Melvin (1964) found that self-punitive behavior is not reduced when discrimination is aided by changing the percentage of shock trials from acquisition to extinction. This past research is inconclusive because it is based on a misinterpretation of what is the critical discrimination for extinction, namely the new response-punishment contingency. Using humans, the present study provides evidence that subjects can and do discriminate the change in percentage, but continue to show self-punitive behavior until they make the discrimination that responding results in shock rather than escape.     

From dispositions to behaviors: The flip side of attribution

The implicational relations between dispositional levels and relevant categories of behavior were investigated. Observers were asked questions about the extent to which persons occupying moderate or extreme positions on an attribute (dispositional) continuum (a) attempt various behaviors, (b) are potentially able to perform various behaviors, and (c) generally emit those same behaviors. Three determinants—central tendency, ability, and social desirabliity—offer a reasonable account of the observed implicational relations. First, persons with a given disposition are not expected to emit behavior that is widely discrepant with that disposition. Second, ability considerations dictate that persons with skillful dispositions are believed capable of unskillful behavior, but unskillful persons are thought relatively incapable of skillful behavior. Third, persons are believed to more frequently attempt socially desirable than socially undesirable behavior. Also, persons with moderate dispositions are believed to actually emit socially desirable behavior more frequently than socially undesirable behavior. Finally, the determinants noted above may be of differing relevance for morality, ability, and preference attributes.     

Attribution of responsibility: A theoretical note

Research on factors influencing attribution of responsibility has resulted in inconsistent and inconclusive findings. A theoretical analysis suggests that Heider's levels of causality represent two dimensions underlying attribution of responsibility. It is suggested that conflicting findings result from failures to control at least one of these two dimensions.     

The sex by race interaction in cognitive measures

Data consisting of 79 cognitive measures from Project TALENT for 100,000 white and black high school students have been analyzed for possible race by sex interactions. Control variables included geographical area, grade in high school, and socio-economic class. Race by sex interactions are largest when socioeconomic class is controlled and are highly related to the size of the main effect of sex as well. White boys and girls differ more than black boys and girls whether the overall sex difference favors males or females. Sex by grade and, to a lesser extent, sex by area interactions were also moderately large and consistent with the size of the main effect of sex. Since there are no consistent relationships with other main effects, and since the measures producing sex differences also tend to produce the interactions, it is concluded that sex differences and the interactions with sex share the same causes. Differences between these results and those of Jensen are also discussed.
