Reactions to threat by defensive and congruent internals and externals: A self-esteem analysis

The hypothesis that vulnerable self-esteem internals and externals would react more defensively to negative intellectual and personality feedback than congruent (more secure self-esteem) internals and externals was investigated in two experiments. The defensive (DE)-congruent (CE) external distinction was strongly confirmed in both cases. In Experiment 1, DEs assumed less personal responsibility for failure than for success, while CEs assumed little personal responsibility for either outcome. Defensive externals performed more poorly than CEs on a task described as an IQ test, suggesting greater anxiety in the face of possible failure. In Experiment 2, DEs rated themselves more favorably and derogated evaluator's competence more than CEs following receipt of negative information regarding their interpersonal skills. Congruent internals (CI) performed more poorly than defensive internals (DI) on the “IQ” task, while male DIs attributed responsibility for outcomes more defensively. It was suggested that a consistently internal view of causation may increase stress in evaluative situations. Implications of these findings for better understanding the relationship between locus of control and maladjustment were discussed, and suggestions for future research were presented.     

Development of strategies for recalling letter sequences

Kindergarten, second-grade, and fourth-grade children (6, 8, and 10 years of age, respectively) were asked to recall letter sequences on a task that required the use of: (a) a verbal strategy; (b) a positional strategy; or (c) either strategy. Additional trials, allowing either strategy, were interspersed among those requiring a verbal or positional strategy; strategy use was determined from performance on these interspersed trials. The results show that children at all grade levels attempted to use a task-appropriate strategy. Performance on the verbal task showed a more marked developmental increase than did performance on the positional task. A second experiment replicated the first with the interspersed trials removed. A third experiment was designed to determine whether letter names interfered with older children's efficient use of a positional strategy. Even with this source of interference removed, the developmental pattern of Experiments 1 and 2 was replicated. There was a Sex by Condition interaction in Experiments 2 and 3 which showed that males do better in the condition requiring a positional strategy, and females do better in the condition requiring a verbal strategy.     

Developmental verbal control of behavior: Implications for self-instructional training

Kindergarten, first-grade, and second-grade children (5, 6, and 7 years of age, respectively) performed a Luria-type verbal control task in which motor responses are initiated to positive stimuli and inhibited to negative stimuli. The task was performed by motor responding only and verbal self-directed motor responding, with these conditions reversed in sequence for one half of each grade group. Although motor responding and verbal-motor responding by the two younger groups were generally poor, their performance equalled that of the second graders when the verbalizing condition followed the silent, motor-only condition. For these children, verbalizing appeared to constitute a second task which interfered with motor responding. Prior practice on motor-only responding, however, facilitated subsequent, concurrent performance of the two tasks. No interference or practice effects were found for the second graders. The results suggested that self-instructional training programs are likely to be successful when adequate verbal-motor coordination can be assumed or when the motor response is within the child's repertoire.     

Increasing and decreasing intrinsic interest with contingent rewards: A test of cognitive evaluation theory

The study examined Deci's (Deci, E. L. Intrinsic motivation. New York: Plenum Press, 1975) hypotheses regarding the effects of contingent rewards on intrinsic task interest. Seventy-two male university students worked on a series of puzzles and were given either a high value reward ($1.50) or a low value reward ($.45). The money was given either contingent upon the simple execution of the task (task-contingent), contingent upon the ostensible attainment of a performance criterion level (criterion-contingent), or noncontingent and unexpected (control). Compared to the high payment control subjects, subjects who received the task-contingent high reward rated the task as less interesting, while subjects who received the criterion-contingent high reward rated it as more interesting. Also, subjects expressed less interest in the task after receiving the high task-contingent reward than the low task-contingent reward, but indicated greater interest after receiving the high criterion-contingent reward than the low criterion-contingent reward. It was concluded that substantial support was obtained for Deci's (1975) cognitive evaluation theory.     

Reactivation-induced interference in a short-term retention paradigm

In Experiment 1 it was demonstrated that interference with a rat's retention of a target spatial cue decreases as the interval between prior conflicting cues and the target increases. Experiment 2 showed that interference can occur even when the interstimulus interval is long, if the memory of a conflicting cue is reactivated just prior to exposing an animal to the target cue. A third experiment suggested that these findings could not be easily interpreted in terms of a stimulus satiation effect. The implications of these findings for a trace decay model of short-term retention were discussed.     

Order of partial and consistent reward,reward magnitude shift,and resistance to extinction

In a separate-phase runway experiment with rats, four schedules involving partial (P) and consistent (C) reward (CC, CP, PC, and PP) were crossed with three reward magnitude shift conditions (upshift, nonshift, and downshift). The data revealed three major findings: (a) Reward magnitude downshift generally led to rapid extinction; (b) consistent reward prior to partial reward (CP) resulted in slower extinction than the reverse order (PC) under conditions of reward magnitude shift (particularly downshift); and (c) the relative performance of PC and CP under conditions of reward magnitude shift was reversed from postshift to extinction. On the basis of these data it was suggested that processes not presently identified by reinforcement level theory and stimulus analyzer theory influence extinction following separate-phase acquisition. A modification of reward level theory was presented to provide an account of extinction performance following separate-phase reward reduction.     

Expressed and inventoried vocational interests as predictors of college graduation and vocational choice

This is a follow-up study of 195 agricultural students originally tested when they entered college in 1970. Students whose Strong Vocational Interest Blank (SVIB) patterns were consistent with their stated choice of major were the congruent sample. Students whose SVIB patterns were inconsistent with their stated choices of major were the discrepant sample. A follow-up was made on graduation rates, eventual major, and job placement. Discrepant subjects changed major more often but graduated at the same rate as congruents. The SVIB did not seem to add anything to the student's expressed interests in predicting college continuation. There was a trend for congruent graduates to more frequently take jobs which matched their majors.     

The gestures of a gorilla: language acquisition in another pongid

A female lowland gorilla, Koko, has been engaged in an ongoing language program since July 1972 when she was 1 year old. During the first 30 months of training she acquired a vocabulary of 100 words in American Sign Language which she spontaneously combined into meaningful and often novel statements of up to 11 signs in length. The gorilla is using a rapidly expanding vocabulary of signs to express semantic and possibly grammatical relations similar to those expressed by human children in the early stages of language acquisition. Patterns of generalization, gradual increase in mean length of utterance, and innovative use of gestural language are discussed in relation to data available on children and chimpanzees.     

The halo effect revisited: Forewarned is not forearmed

The purpose of the present research was to determine if forewarning subjects about the halo effect eliminated the effect or made people aware of its impact. The research was a replication and extension of R. E. Nisbett and T. D. Wilson's (Journal of Personality and Social Psychology, 1977, 35, 250–256) experiment on the halo effect. Subjects viewed an interview of a college instructor who was either warm or cold and then rated his physical appearance, mannerisms, and French accent. Some subjects were told to introspect about their cognitive processes while viewing the interview and were told that the purpose of the study was to see how aware they were of the determinants of their ratings. Other subjects were also told specifically what the halo effect was and given a motivation either to show it or not to show it. In addition, a measurement technique different from that used by Nisbett and Wilson was utilized to allow a more precise measurement of awareness, and a new cover story was used to make the task more involving and important to subjects. Despite these attempts to eliminate the halo effect (or, at a minimum, to make people aware of it), the results indicated that subjects in all conditions were very susceptible to it. That is, subjects who viewed the warm version of the interview rated the instructor's appearance, mannerisms, and accent significantly higher than did those who viewed the cold version, even when informed and forewarned about this effect. The forewarning and introspection instructions also had no impact on subject's awareness of the halo effect. Subjects in all conditions indicated that their liking for the instructor had had only a minimal effect on their ratings.     

Mechanisms for the cueing phenomenon: The addition of the cueing context to the training memory

A series of three experiments was run to test the hypothesis that when animals are exposed to a cue from prior training, the context in which cueing occurs becomes associated with the training memory. The first experiment demonstrates that when rats are trained to avoid in one context and then are tested in a different context performance is reduced. Experiments 2 and 3 demonstrate that this performance deficit can be alleviated by cueing the rats in the test context prior to testing. The data suggested that the improved performance does not seem to result from the association of the cueing context with a fear response. These results are discussed in relation to the context addition hypothesis.
