Effects of relative nurturance and social power on observational learning and imitation

Preschool children observed two models, one of whom (controller of resources) controlled rewards dispensed to the child and to the other model (rival consumer of resources). The nurturance of the controller was varied in terms of his relative generosity towards the subject and rival consumer. Controllers were imitated to a greater extent than consumers only when the controller had been more nurturant to the child than to the rival consumer. Imitation of the controller and consumer were affected differently by the various conditions of nurturance, but children's learning of each model's behaviors were affected similarly by the conditions. The learning and imitative performance of each model's behaviors were uncorrelated, and imitation of one model did not correlate with imitation of the other. However, the learning of the two models' behaviors was highly correlated.     

Behavioral confirmation in social interaction: From social perception to social reality

A perceiver's actions, although based upon initially erroneous beliefs about a target individual may channel social interaction in ways that cause the behavior of the target to confirm the perceiver's beliefs. To chart this process of behavioral confirmation, we observed successive interactions between one target and two perceivers. In the first interaction, targets who interacted with perceivers who anticipated hostile partners displayed greater behavioral hostility than targets whose perceivers expected nonhostile partners. Only when targets regarded their actions as reflections of personal dispositions did these behavioral differences in hostility persevere into their subsequent interactions with naive perceivers who had no prior knowledge about them. Theoretical implications of the behavioral confirmation construct for social perception processes are discussed.     

Partial reinforcement and autoshaping of the pigeon's key-peck behavior

Pigeons were exposed to continuous and partial reinforcement (25%) schedules in an autoshaping procedure. The number of trials and/or pairings per session were equated across two factorial group sets and all groups were trained for a fixed total number of acquisition trials (192). When acquisition was analyzed as a function of reinforcements delivered, the groups receiving fewer number of trials per session acquired the response faster, independently of the percentage of reinforced trials. Moreover, the number of reinforcements to satisfy an acquisition criterion was a monotonic function of the number of trials per session but not of the schedule. The results are discussed in relation to the neocontinuity and the scalar expectancy theories.     

A note on the dynamics of work adjustment

The process of work adjustment, as derived from the Theory of Work Adjustment, is presented in a systems-type model. The model integrates the original propositions of the theory with the more recent work on personality-style dimensions. The mechanisms of adjustment to work are discussed to emphasize the dynamic nature of the complete work-adjustment process. The constructs of Work Behavior and Organizational Behavior are introduced as intervening variables in the adjustment process. It is also shown that the forecasting of work adjustment requires the addition of the constructs of Abilities and Ability Requirements.     

Anticipation of reward omission as a cue for choice behavior

A within-subject partial reinforcement extinction effect was obtained in a conditional discriminative choice task. In choice acquisition, one group had learned a task in which one choice alternative was continuously reinforced (CRF) and the other alternative was partially reinforced (PRF). Most errors in the acquisition phase were the choosing of the CRF lever when the conditional stimulus signaled the PRF lever; in extinction this pattern of choice errors reversed. In extinction, most errors were choosing of the PRF lever when the conditional stimulus signaled the CRF lever. The predictions of frustration theory and sequential theory were compared with the choice data. The results were interpreted as consistent with the anticipatory frustration construct within an associative mediational theory.     

Experimental validation of two MIQ scales

Two Minnesota Importance Questionnaire (MIQ) scales, Creativity and Independence were validated by experiment. Subjects were exposed to four task conditions representing joint combinations of high or low levels of Creativity and Independence. As a behavioral criterion of preference, subjects were then required to work for 12 sessions, each session under any (of the four) task condition of their choice. The behavioral results were consistent with the subjects' MIQ score levels on the two scales, thereby validating the scales.     

A thematic coding system for the intimacy motive

A new thematic (TAT) measure of intimacy motivation was developed and cross-validated in four separate arousal studies using three different college populations. A brief sketch of the derived thematic scoring system for intimacy motivation was presented. The goal state of the intimacy motive was defined as experiencing a warm, close, and communicative exchange with another person. In a college sample, subjects scoring high on the intimacy motive were rated by friends and acquaintances as significantly more “warm,” “natural,” “sincere,” “loving,” and “appreciative” and less “dominant,” “outspoken,” and “self-centered” than subjects scoring lower. The results were discussed in terms of the theories of Sullivan on the need for interpersonal intimacy, Maslow on growth motivation and “B-love,” Bakan on communion, and Buber on the I-Thou relation. Differences between the new coding system and the need for Affiliation (n Aff) system for scoring imaginative productions were also suggested.     

A multivariate investigation of the reinforcer structure of occupations

Earlier research based on 81 Occupational Reinforcer Patterns (ORPs) suggested a nine-category classification of occupations. The present research, based on 148 ORPs, investigated the ability of that classificatory system to assimilate new information. Cluster analysis of the 148 ORPs yielded an eight-category classification of occupations in which five of the original occupational clusters appeared virtually unchanged; the other four original clusters were combined into two occupational clusters. One new cluster was identified. Principal factors analysis was employed to study the factor structure of the occupational reinforcers and to highlight the essential nature of the classificatory system. Five reinforcer factors were identified.     

A developmental study of semantic elaboration and interpretation in recognition memory

Two experiments examined semantic elaboration and interpretation in recognition memory of 4-year-olds and college students. Subjects were presented pictures of color-specific and non-color-specific items, and then tested for their recognition of the chroma of the items. In Experiment 1, one-half of the presentation items were black and white and one-half colored, and testing always involved one black and white and one colored choice. In Experiment 2, all of the presentation items were colored, and testing always involved two colored choices. In both studies, the pattern of results of the two age groups was similar. Experiments 1 and 2 indicated that recognition judgments were based on representations that were elaborated with preexperimentally acquired semantic color information, and Experiment 2 also indicated that recognition judgments were based on representations that contained interpretive information about the appropriateness of the colors of the items. The results were considered to support and extend the view that when young children and adults share a common knowledge base, they are likely to engage in similar and extensive semantic processing.     

Two tests of Maslow's theory of need fulfillment

In a two-part test of Maslow's theory of human motivation, two relationships were explored: (1) the relationship between need importance and need deficiencies, and (2) the relationship between need deficiencies and life satisfaction. The subjects were groups of women college graduates in three types of occupations: professional-managerial, clerical-sales, and homemaking. In the first study, group differences in actual deficiencies did not support the hypothesis that need importance is negatively correlated with need deficiencies. Rankings of the deficiencies for the three groups, however, were consistent with the hypothesized relationship, as were the small but significant correlations that were obtained between need importance and deficiency values. In the second study, the findings gave partial support to Maslow's theory in that a significant relationship was found between need fulfillment and life satisfaction for two of the three occupational groups. The findings of both studies are discussed in relation to considerations in women's career development.     

The relationship between perception and production of /w/, /r/, and /l/ by three-year-old children

Twenty-one normally developing 3-year-old children were tested on two approximant consonant contrasts, rake-lake and wake-rake, and a control contrast, wake-bake. Perception was assessed in a two-choice picture identification paradigm; stimuli were (1) natural and computer synthesized “clear cases” of the minimal pairs, and (2) synthetic stimulus series which interpolated on acoustic dimensions that differentiate the minimal pairs. As a group, the children showed very accurate perception of the minimal pairs. Performance on the synthetic series yielded consistent identification of the endpoint stimuli and monotonic functions with abrupt crossovers at the phoneme boundary. Children who did not yet articulate /r/ and /l/ appropriately showed somewhat less consistent perception than children who produced all phonemes correctly.     

Aversive CS control of instrumental avoidance as a function of selected parameters and method of Pavlovian conditioning

Effects of aversive CSs upon dogs' instrumental avoidance responding were assessed as a function of the Pavlovian conditioning parameters using off-baseline (Experiment 1) and on-baseline (Experiment 2) conditioning procedures. In each experiment, three UCS intensitites (2, 6, and 10 mA) were crossed factorially with two CS-UCS intervals (10 and 90 sec) yielding six groups. After 4 days of conditioning, the CS-produced effects on avoidance were determined primarily by an interaction between Pavlovian procedure (off- versus on-baseline) and UCS intensity. With off-baseline conditioning, CS-produced facilitation of avoidance was an increasing function of the UCS intensity. However, with on-baseline conditioning, only the CS paired with weak UCS facilitated avoidance, and the CS paired with the strong UCS suppressed responding. This reversing parametric function poses problems for two-process motivational theories of avoidance.
