Exposure effects in person perception: Familiarity,similarity, and attraction

Two experiments explored the relationship between familiarity, similarity, and attraction. In the first experiment, subjects viewed photographs of faces at various exposure frequencies and then rated them for likeableness and similarity. Familiar people were regarded by the subjects as both more likeable and more similar to themselves. The effects of familiarity on perceived similarity were primarily mediated by changes in attraction, although some evidence of a direct link between familiarity and perceived similarity was also found. In the second experiment, subjects viewed the same stimuli at a single exposure frequency, and received bogus information regarding the similarity of the people shown therein. Subsequent ratings of likeableness and perceived familiarity revealed that people who seemed similar to the subjects were regarded as both more likeable and more familiar. The effects of similarity on perceived familiarity were almost entirely mediated by changes in attraction. Some of the theoretical implications of these findings are discussed.     

Self-evaluation,self-reinforcement,and locus of control

Two verbal recognition memory tests were administered to 24 internals and 24 externals. Subjects were required to self-evaluate (SE) their responses on the first test and both SE and self-reinforce (SR) on the second. There were no internal-external differences in performance accuracy on either task, but internals gave themselves consistently higher self-evaluations, administered more positive SR and less negative SR. There were no differences in the criteria used by the two groups for SR. SR differences appeared to be a function of the differential SE. It was suggested that external locus of control could be viewed as a self-regulation deficit. Externals are hypothesized to be unable to evaluate their own behavior adequately in the absence of external input and therefore do not make effective use of self-reinforcement. Discussion also made reference to the process of self-regulation.     

Developmental changes in the semantic processing of pictures and words

Second- and fifth-graders' semantic decision times for pictures and words were analyzed relative to the predictions derived from unitary- and dual-memory models. At both grade levels, word-word response latencies were greater than picture-word latencies which, in turn, were greater than picture-picture latencies. An interaction between Grade and Condition indicated that verbal access times decreased more than pictorial access times. The data fit the predictions of a memory model postulating category storage in a single memory system as opposed to simultaneous representation in verbal and nonverbal memory systems. It was concluded that with increasing experience verbal access to this single semantic system is more rapid.     

Self-consciousness, outcome expectancy, and persistence

A study investigated persistence as a function of two variables: the disposition to be self-attentive (called private self-consciousness) and outcome feedback on a prior task that was described as closely related to the target task. More specifically, subjects first completed a concealed-figures test and were told that their performances were either very good or very poor. The second test, which ostensibly measured the same abilities, was an insolvable design problem that is commonly used to measure persistence. Feedback concerning prior outcomes had a direct influence on expectancies for the second task, but persistence on that task was a joint function of feedback and self-consciousness. That is, favorable feedback led to greater persistence than did unfavorable feedback, but only among subjects high in self-consciousness. This finding replicates and extends the results of several previous studies. Discussion centers on the relationship between the present research and an earlier experiment which yielded apparently different results.     

Self-consciousness, self-awareness, and self-attribution

Self-awareness was either manipulated by a mirror (experimental) or not (control). Subjects were selected for being high or low in private self-consciousness (disposition to attend to one's thoughts, feelings, motives). Private self-consciousness had a stronger effect on self-attributions than did self-awareness. These findings have implications for attribution, self-consciousness, and the relationship between manipulations and dispositions.     

Texture gradient registration and the development of slant perception.

The processes underlying the development of slant perception were investigated by manipulating the degree of texture element variability. Subjects at four grade levels were required to make judgments of physical slant of surfaces with three levels of variability. Absolute error of judgment decreased with age, but texture variability had no effect at any grade level. The results suggest that there is no improvement in the ability to extract gradient information. Rather, improvement in the consistency of judgment reflects a developmental change in the relationship between stimulus information and judgment.     

Knowledge of one's own responding and the relation of such knowledge to learning: A developmental study

First-, third-, fifth-grade children, and college students (ages 6, 8, 10, and 19 years) acquired a paired-associate list under the study-test procedure to a one error-less trial criterion. In addition, as each pair was presented the individual indicated whether he/she had that pair correct on the immediately preceding trial (postdiction responses). The data were interpreted in terms of a discrimination-utilization hypothesis which postulates that individuals discriminate their own correct and incorrect responses on a given trial and use this information for distributing processing effort on the subsequent trial. Analyses involving the accuracy of postdiction responses, the relation of postdiction accuracy to acquisition, and the consideration of the acquisition data in terms of a two-stage model led to the conclusion that older children and adults may use the discrimination-utilization strategy but younger children tend not to use it, probably because of both mediation and production deficiencies.     

Self-consciousness,self-report of aggressiveness,and aggression

Private self-consciousness consists of attending to one's thoughts, feelings, and motives. Public self-consciousness consists of attending to oneself as a social object. The effect of dispositional self-consciousness on the accuracy of self-reports was studied in research on aggression. High- and low-private self-conscious subjects rated their own aggressiveness. Several weeks later their aggressive behavior was objectively measured. The correlation between self-report of aggressiveness and aggressive behavior was significantly higher for high-than for low-private self-conscious subjects. The correlation between self-report and behavior was unaffected by public self-consciousness. The implications of these findings for self-consciousness theory and personality dispositions are discussed.     

Procedures for synthesizing ratio judgements

Requirements which seem reasonable for functions synthesizing judgements (quantities or their ratios), in particular separability, associativity or bisymmetry, cancellativity, consensus, reciprocal or homogeneity properties are investigated and all functions satisfying them are determined.     

Transfer of the signaling properties of aversive CSs to an instrumental appetitive discrimination

Rats received Pavlovian conditioning in which, based on a shock US, white noise was established for different groups as an aversive CS+, CSo, or CS?. Then, half of each group received the CS contingent upon either the food-reinforced or nonreinforced response in an easy, choice discrimination. Correct responses, i.e., number of reinforcements, to criterion showed that a CS+ for the reinforced response facilitated learning, whereas a CS? retarded learning; conversely, a CS+ for the nonreinforced response retarded learning, whereas a CS? facilitated learning. The same contingency difference occurred with errors to criterion for CS? subjects but was obscured for CS+ subjects apparently by an avoidance-producing effect of the CS+. In support of the generality of the transfer effect, Z-score transforms of the correct-response data showed that the magnitude of transfer was comparable to that obtained in more difficult discriminations. Collectively, the findings indicate that an aversive CS can function as a transformed signal for the presence (CS+) or absence (CS?) of an appetitive reinforcer and that the signal's control of behavior is via a within-chain mediational process.     

Acquisition of representation-mediated conditioned food aversions

Food aversions were established in rats by administering lithium chloride (LiCl) immediately after the presentation of an exteroceptive conditioned stimulus (CS) which previously had been paired with a food substance. In Experiment 1, rats which received first tone-food and then tone-LiCl pairings showed less food consumption in subsequent testing than rats which received only tone-food or tone-LiCl pairings. Experiments 2 and 3 demonstrated the stimulus specificity of aversions established in this manner. Rats which first received pairings of light and tone CSs with two different food substances and then received pairings of one of those CSs with LiCl showed greater aversion to the food previously associated with the LiCl-paired CS than to the other food substance. Experiment 3 also showed that specific aversions were not acquired if rats received CS-shock rather than CS-LiCl pairings. These results suggest that CS-evoked representations of events can substitute for those events themselves in the formation of new associations.     

Inconsistency and rank preservation

Conditions for rank preservation in a positive reciprocal matrix that is inconsistent are provided. Three methods of deriving ratio estimates are examined: the eigenvalue, the logarithmic least squares, and the least squares methods. It is shown that only the principal eigenvector directly deals with the question of inconsistency and captures the rank order inherent in the inconsistent data.     

Causal attributions and information seeking to explain success and failure

Previous studies of attributions for success and failure have relied upon a theoretically derived set of causal attributions, either luck versus skill (derived from Rotter, 1966) or ability, effort, luck, and task difficulty (Weiner et al., 1971; Weiner, 1972). The same tendency of relying upon a set of logically derived cues has been evident in investigations of information-processing in making attributional judgments for success and failure (e.g., Fontaine, 1972; Frieze & Weiner, 1971). Two studies were conducted which employed an open-ended format to determine the relevance of the causal categories and information which have been utilized in previous studies. Results of these studies supported the validity of previously employed causal categories and information cues as well as establishing other important but previously ignored causes and sources of information.     

Texture gradient effectiveness in the perception of surface slant

To assess the development of monocular slant perception as well as the relative effectiveness of different sources of information, children in first, third, and fifth grades and college adults were asked to make judgments of surface slant on the basis of monocular texture gradient information. Accuracy of judgment increased with increasing age. In addition, differences in gradient effectiveness were found. Compression gradients were relatively ineffective sources of information, whereas perspective and multiple gradients resulted in greater accuracy. The results suggest limitations on the specificity of certain forms of gradients.     

Developmental changes in free recall: The interaction of task structure and age

Free-recall learning and organization were measured for 3rd, 7th, and 11th graders under conditions which varied the type and amount of task structure. Task structure for the input or list-presentation phase was manipulated by using a random, constant, or alphabetic item sequence across trials. Task structure for the output or recall phase was manipulated by providing standard instructions or instructions which suggested the possible use of an alphabetic ordering scheme. Recall performance and organization showed an interaction between age and both manipulations of task structure. The 3rd graders required the maximal amount of task structure (alphabetic order with alphabetic instructions) to demonstrate recall facilitation relative to the completely unstructured control condition. The 7th graders showed recall facilitation for intermediate and high levels of task structure, and the 11th graders showed recall facilitation for low, intermediate, and high levels of task structure. The results are related to current hypotheses about developmental changes in recall performance and their relationship to changes in the systematic use of organizational strategies.     

Reading skill and the minimum distance principle: A comparison of listening and reading comprehension

Experiment I compared the listening and reading comprehension of sentences which follow the Minimum Distance Principle, e.g., John tells Bill to bake the cake, and of those which do not, e.g., John promises Bill to bake the cake. Third, fourth, and fifth graders were tested. Support for Chomsky's Stage analysis of mastery of the Minimum Distance Principle was found for the listening but not for the reading task. Reading skill level was found to be positively correlated with Stage and a significantly better predictor of promise performance than was age or IQ. Experiment II investigated the effect of the composition of the experimental presentation list on performance by comparing comprehension when the list contained only promise or tell sentences with that obtained when the list contained both types of sentences. For half the subjects, performance differed as a function of the list composition: Implications of these findings for the assessment of the development of language competence are discussed.     

Sex differences in retention of verbal and spatial characteristics of stimuli

Males and females from Grades 3, 6, and college viewed sets of five or seven letters in a 4 × 4 matrix, and remembered either (a) names of the letters, (b) positions of the letters within the matrix, or (c) both letters and positions. At all grade levels females remembered letters more accurately than positions, while males remembered letters and positions equally well. However, there was also evidence that verbal and spatial information was processed independently by both males and females. Results are discussed in terms of neurological development and sex differences in specific abilities.
