The Wall-Seeking Tendency and Maze Learning in the White Rat

A partial replication and extension of the semantic differential was used to test the effects of modified middle interval instructions on rotated factor loadings derived from Ss' responses. The partial replication is in good agreement with the findings published by Osgood et al. (5). However, the results from Ss responding to the modified middle interval instructions differ markedly from those in published and control conditions, yielding an interpretable fourth factor suggesting the achievement of more subtle nuance of meaning.     

Social Behaviors as Determined by Different Arrangements of Social Consequences: Diffusion of Responsibility Effects With Competition

Abstract

According to a recently proposed synthesis, social loafing, social facilitation, and deindividuation can be viewed as different ways of arranging social consequences (B. Guerin, 1999). The effects of such arrangements have been measured in past research as productive output (social loafing and social facilitation) or as antinormative behaviors (deindividuation), but all 3 effects are manipulable by changing individual identifiability, evaluation, social identity, task difficulty, and presence in a group. The synthesis also predicted that these same variables would apply to other measures and other arrangements of social consequences. To this end, in the present 2 experiments, the author varied the arrangements for consequence diffusion in a competition situation by varying small and large competing groups and measured productive output and antinormative behaviors simultaneously. The 2 experiments showed social-consequence effects in competition situations with college students, giving further support for the social-consequence synthesis and the idea that the verbal naming of phenomena in social psychology is arbitrary.     

The Effects of Visual Orientation on the Maze Learning Ability of the White Rat

Since most studies which employ sociometric measures have either ignored the sensitivity of these measures to changes in group structure or have failed to indicate the relative sensitivity of the different types of measures across time and at different age levels, a way to categorize sociometric responses according to the usefulness in reflecting changes both across time and at various age levels was hypothesized. A total of 607 students in grades four through eight responded to a sociometric questionnaire. These responses were analyzed by obtaining test-retest correlations for choices given, choices received, and reciprocal choices. The results indicate that reciprocal choices are less affected by age and time changes than all other ways of interpreting sociometric data.     

Variation of Isometric Response Force in the Rat

Hungry, unrestrained rats (N = 7) were rewarded for pressing a response beam in excess of 11 different force requirements. Changes in peak force production as a function of peak force requirement were examined by analyses of the first four moments of distributions of peak response forces: constant error, the within-subject standard deviation, skewness, and kurtosis. Results were similar to those previously obtained with human subjects: Constant error was positive at low and negative at high force requirements, the within-subject standard deviation increased as a negatively accelerating function of force requirement, and skewness and kurtosis were positive at low force requirements and decreased to negative values at the highest increments. Additional analyses of response kinetics indicated that rats, like humans, meet increasing force requirements by altering the rate of rise of force. The performance similarities suggest that common processes are engaged by the human and rat motor control systems to solve the problem of generating forces that are appropriate to the prevailing environmental constraints.     

The SameP-Relation as a Response to Critics of Baker's Theory of Constitution

According to the so-called “standard account” regarding the problem of material constitution, a statue and a lump of clay that makes it up are not identical. The usual objection is that this view yields many objects in the same place at the same time. Lynne Rudder Baker's theory of constitution is a recent and sophisticated version of the standard account. She argues that the aforementioned objection can be answered by defining a relation of being the same P as (sameP). In this paper I shall examine consequences of her response and show that sameP has wrong formal properties, as a result of which this solution cannot be accepted.     

The Validity of Defecation as a Measure of Emotionality in the Rat

The present study employed a free operant discrimination procedure in studying the effects of frontal ablations in rats. Two groups of Ss were trained on a multiple fixed ratio (FR) 3 extinction schedule, and then the experimental group received frontal lesions. Following recovery they were returned to the multiple schedule. It was found that for the experimental group there was a significant loss in discrimination following frontal lesions. These results support a study done by Weiskrantz and Mishkin (8).     

The Effects of Visual Orientation with the Removal of Hunger and Food on the Maze Learning Ability of the White Rat

In a test of the hypothesis that coding used for recall is a dynamic process that changes in accordance with operational structures, 50 men and women university students participated in two task sessions: (a) formal operations and recall and (b) recall one month later. Significant correlations supported the basic hypothesis. Two-way repeated measures analyses of variance indicated significant main effects for formal operational thinking and for the quality of discovered problems but showed no interaction between each of these variables and time. Analysis of Ss' responses to the discovered problems task raised questions about the type of subjective organization in evidence at the formal operations level     

齐地新出土战国至汉代三盏青铜灯

战国时期的金属工艺进入了更新的历史阶段,铜灯具作为青铜器文化中一种后起的新生事物,在战国时期上层人物中已经被普遍使用,陶灯具也成为人们日常生活中不可缺少的照明用器.从目前出土的文物资料看,战国时期的青铜灯具数量不多,大约有十几盏,此外有大批的陶灯具.盛行于战国至汉代时期的青铜灯,形式多样.常见的灯上有浅盘,中有柱,下有底座;还有一种盘边有柄,下置三足,称"行灯".再有一些灯制作成人形、兽形、鸟形、树形、杯形等,样式繁多,多属贵族使用.     

Effect of Injected Adrenalin on an Avoidance Response in the Rat

It was hypothesized that slight modifications in word association test (WAT) instructions would have no discernable effect on the responses of college students, but would produce significantly different response hierarchies generated by young children. Seventy-five adults and 375 children gave WAT responses to 32 stimulus words. One-third of the Ss, at each of six grade levels, was given standard WAT instructions; one-third was given a practice session with 10 additional words; and the remainder were instructed to respond to stimulus words with the “first thing” that came to mind. Although the different instructional sets had no discernable effect on the adult Ss, they had a significant effect (ps < .05) upon the number of (a) multiple-word and nonword responses, (b) paradigmatic responses, and (c) idiosyncratic responses produced by the children. These differences suggest that caution be used in the interpretation of WAT responses provided by young Ss.     

The Determiners of Energy Expenditure in String-Pulling by the Rat

A follow-up was made of 18 male dyslexic children (RDs) and a group of matched controls (Cs), who had all been judged free from emotional and school adjustment problems two years earlier, (a) to see if RDs' reading deficit had been overcome, (b) to measure “emotional overlay,” and (c) to find predictors of success in learning to read. Results showed that at the time of the follow-up (a) none of the RDs had overcome his reading disability despite remediational efforts; (b) RDs had significantly lower achievement levels and significantly more adjustment problems than Cs; (c) low scores for WISC Full Scale IQ, Vocabulary subtest, and Coding subtest were associated with large reading deficits two years later; and (d) high WISC Arithmetic and Coding subtest scores were associated with large gains in reading skill. Physiological measures did not predict size of deficit or gain in reading skill over time.     

Response to Bill of Rights Paraphrases as Influenced by the Hip or Straight Attire of the Opinion Solicitor1

A sample of 375 white middle class residents of suburban Sacramento was randomly distributed among 3 experimental conditions of exposure to paraphrases of the Bill of Rights. The paraphrases were in the form of letters to the “Subcommittee on Crime and Disorder” of the California State Senate. A far greater proportion of subjects would endorse a “negative”, somewhat authoritarian version of the Bill of Rights than would sign either a “real” paraphrase of the original text or a rather equivocal “wishy-washy” bill. A minority of those shown the “real” bill would sign it. Solicitors dressed as “straights” were more likely to elicit signatures from subjects than were “hips”. The latter effect was observable, however, only for subjects in the negative and to a lesser extent the wishy-washy bill conditions. When the “real” bill was presented the attire of the solicitor made no difference. While an alternative interpretation was viable, the results were explained in terms of reactance (Brehm, 1966) and Rokeach's (Rokeach & Mezei, 1966) hypothesis that liking is mediated by inferred congruity of beliefs.     

Response Complexity and the Latency of Different Movement Patterns

Two series of experiments are described in which RT of responses of varying complexity is investigated. Complexity of arm movements was manipulated in terms of (a) the amount of force exerted in resisted movements, (b) the distance moved by the limb and the direction of movement, using reversing or continuing movements, and (c) the combining of the arms in reversing and continuing movements. Simple and two-choice RT situations were used. As response complexity increased in terms of the number of sets of response units that have to be organized into a spatio-temporal sequence, the latency correspondingly increased. However latency was not affected by changes in the amount of force exerted, or in simple reversal movements. The implications of these results are discussed.
