Trait attribution to a described action as a function of changes in salient information

The relative importance of five information variables in determining the amount of friendliness attributed to a described action was analyzed using a five-way ANOVA. The variables (a) antecedent condition, (b) disposition of the actor, (c) intent of the actor, (d) likely social outcome of the act, and (e) actual social outcome of the act, were given a high friendliness value and a low friendliness value. Thirty-two stories which described the same act, but which systematically differed in background information, were made by combining one of the two values of the five variables in all possible combinations. Senior secondary school girls read the stories and rated the friendliness of the act and the friendliness of the actor on 9-place, unipolar rating scales. Results showed that the intent of the actor contributed the only significant source of variance to the trait attribution to the act. The trait attribution to the actor was significantly influenced by intent, antecedent condition, and disposition.     

Cognitive tuning and receptivity to novel information

An experiment was conducted to test the hypothesis that cognitive tuning would cause receivers to be more receptive to novel than to familiar information, compared to transmitters. The information receptivity of transmitters and receivers was contrasted against a control group. The influence of the source and audience, possible limits on the influence of the tuning set, was also explored. Finally, amount of variance controlled by cognitive tuning, personality variables and information utility were examined.While the results strongly support the prediction that transmitters prefer familiar information, receivers and control group subjects did not significantly differ in preferences for novel information. The anticipated expertise of source or audience had no influence on information receptivity. Among the three sets of variables used, the greatest amount of variance was explained by information utility, followed by cognitive tuning and personality measures, though all three variables controlled a significant amount of variance.     

Decision processes in children's recognition memory

Kindergarteners and third graders were given a continuous recognition memory task involving two-digit numbers. In addition, a rating scale consisting of photographs of various facial expressions was used to obtain confidence judgments from the Ss. Conventional analyses as well as signal detection analyses of the data revealed the following results: (a) the overall performance of the third graders was superior to that of the kindergarteners; (b) memory strength decreased as the number of intervening items increased; (c) there was no difference in the forgetting rates of the two grade levels; (d) the third graders exhibited a more liberal response bias than the kindergarteners; (e) both the hit rate (probability of correctly labeling an old stimulus as old) and the false-alarm rate (probability of incorrectly labeling a new stimulus as old) increased across blocks of items; (f) the increases in the hit rate and the false-alarm rate over blocks were due to a change in criterion from a relatively conservative level to a more lenient one; (g) the lower the S's level of confidence in judging an item as old, the lower was the probability of that item actually being old; (h) the third graders were better than the kindergarteners at gauging the accuracy of their recognition responses. It was concluded that with respect to recognition memory, chidren as young as $\text{5}\text{1}\text{2}$ years old are capable, to some extent, of monitoring their own memory states.     

Avoidance conditioning as a function of appetitive stimulus pretraining: Response and stimulus transfer effects

Pretrained appetitive discriminative stimuli were used as warning signals in subsequent avoidance learning. In Expt 1 identical responses were required in pretraining and in avoidance learning. An appetitive S+ facilitated avoidance learning in rats in comparison to S? or a stimulus previously uncorrelated with food. In Expt 2, the type of response in pretraining and in avoidance learning was varied. Groups with homogeneous responses in the two situations replicated Expt 1 results, whereas groups with different responses in pretraining and avoidance learning failed to show an advantage when S+ served as warning; in the heterogeneous response groups, S? was as effective as S+. Inhibitory factors in the heterogeneous groups were discussed as an explanation for these results.     

Summation of food and shock based responding

In a multiphase experiment, dogs first received discriminative, discretetrial, barrier-jumping training with two tones (S^D, S^Δ) in a shuttle box reinforced by either shock avoidance (Group I) or by food (Group II). Then the dogs were trained on free-operant barrier-jumping reinforced by the qualitatively opposite reinforcer—food in Group I and shock avoidance in Group II. Finally, test presentations of the tone stimuli were superimposed on the free-operant behavior. The tone S^Ds markedly facilitated responding in all animals. This experiment demonstrates a summation of responding maintained by shock avoidance and food reinforcement and casts doubt on explanations of conditioned suppression outcomes that appeal solely to incompatible motivational states within the organism.     

The inheritance of cognitive interest styles among twins

Through twin studies, research in behavioral genetics has demonstrated significant genetic components in many personality traits. Less research has been done on inheritance of vocational interest preferences, partially because of the lack of a wholistic conceptual model for understanding the relationships among diverse occupational interests. With the development of scales for the Strong Vocational Interest Blank (SVIB) to measure the six cognitive interest styles propounded by Holland, a parsimonious and comprehensive mapping of the occupational world was available and lent itself to the study of measuring inheritance of vocational preferences among twins. Median intraclass correlations for 409 pairs of monozygotic males, tested with the SVIB, was r = .50; for 570 pairs of monozygotic females, r = .55; for 237 pairs of dizygotic males, r = .27; and for 370 pairs of dizygotic females, r= .27.     

Syntactic facilitation of children's associative learning: An instructional effect

An experiment is reported in which connective recall, as well as noun recall, was obtained in a pair-associate learning, syntactic facilitation paradigm. Dfferences in the pattern of noun and connective recall, and a partial independence in the two types of recall, were obtained. These results were interpreted as consistent with the hypothesis that experimenter-supplied verb links facilitate noun pair learning by serving an instructional role, indicating to the subject how a pair might be coded.     

Related factors of the Survey of Study Habits and Attitudes and the Vocational Preference Inventory

The Survey of Study Habits and Attitudes (SSHA) and the Vocational Preference Inventory (VPI) were administered to 100 undergraduates. The scales of the two instruments were compared using canonical analysis. The analysis revealed a relationship between a component of the SSHA and a component of the VPI which accounted for 31% of the variance of the two instruments. The related components were interpreted as indicating that a dimension running from an academic orientation to a nonacademic orientation was measured by certain scales of each instrument.
