The effect of Russian versus Hebrew instructions on the reaction to social pressure of Russian-born Israeli children

An experiment on the role of the language of instruction in mediating responses to social pressure was conducted with a sample of 41 Russian-born adolescents who had recently immigrated to Israel. The subjects were asked to respond to a series of conflict situations in which they were told that either the experimenters, their own parents, or their peers would see their answers. Instructions were given once in Russian and once in Hebrew. Contrary to the principal hypothesis, when subjected to pressure from adults the children gave more conventional moral responses under Hebrew than under Russian instructions. The result was interpreted as reflecting the tendency to respond more moralistically to the language of authority, which, for the emigréchildren, shifted from Russian to Hebrew. Regardless of the language of administration, the scores for the emigréchildren fell between those for Soviet and Israeli youngsters, but they were closer to the latter. Within the sample, the longer a child lived in one or the other society, the more his response to social pressure resembled the modal reaction of children in that society. Children from families who had or had not spoken Yiddish in the home showed marked differences in response, with the former resembling the Israeli and the latter the typical Soviet reaction. The results were interpreted as reflecting the capacity of children to adapt to conflicting socialization settings both within and across cultures.     

Reducing the tendency to self-handicap: The effect of self-affirmation

Self-handicapping, the creating or claiming of obstacles to one’s performance to influence explanations given for subsequent outcomes, has been shown to have a host of attitudinal and behavioral consequences. Given the wide ranging impact of self-handicapping, it is important to understand the conditions under which self-handicapping is more or less likely to occur. Accordingly, the present study tested the hypothesis that people will be less likely to engage in self-handicapping if they have previously engaged in self-affirmation. The results of this study found that self-affirmation was more effective in reducing self-handicapping behavior when individuals experienced non-contingent success than when they experience contingent success. Theoretical contributions to the self-handicapping and self-affirmation literatures are discussed, as are practical implications.     

The bimean: A measure of central tendency that accommodates outliers

Observations that depart considerably from the center of a distribution demand special consideration. They may be retained, trimmed, or weighted less than other data. This article provides a BASIC program that implements Mosteller and Tukey’s (1977) technique for weighting observations less as they depart from the middle of a distribution. Influence curves for this “bisquare-weighted mean,” or “bimean,” are displayed and compared with more traditional measures of central tendency.     

The effect of instructions on the judgement of brightness

A brightness constancy experiment using ten subjects showed that different instructions significantly affect the subject's PSE judgement. Variations in the reflectance of the standard target and in the background and illumination of the variable target did not influence the effect of different instructions. The use of the D-ratio as constancy index in this study confirms an earlier theoretical finding that other brightness constancy ratios introduce an artefact into experimental results.     

The modality shift effect and the effectiveness of warning signals in different modalities

Which is better, a visual or an auditory warning signal? Initial findings suggested that an auditory signal was more effective, speeding reaction to a target more than a visual warning signal, particularly at brief foreperiods [Bertelson, P., & Tisseyre, F. (1969). The time-course of preparation: confirmatory results with visual and auditory warning signals. Acta Psychologica, 30. In W.G. Koster (Ed.), Attention and Performance II (pp. 145-154); Davis, R., & Green, F. A. (1969). Intersensory differences in the effect of warning signals on reaction time. Acta Psychologica, 30. In W.G. Koster (Ed.), Attention and Performance II (pp. 155-167)]. This led to the hypothesis that an auditory signal is more alerting than a visual warning signal [Sanders, A. F. (1975). The foreperiod effect revisited. Quarterly Journal of Experimental Psychology, 27, 591-598; Posner, M. I., Nissen, M. J., & Klein, R. M. (1976). Visual dominance: an information-processing account of its origins and significance. Psychological Review, 83, 157-171]. Recently [Turatto, M., Benso, F., Galfano, G., & Umilta, C. (2002). Nonspatial attentional shifts between audition and vision. Journal of Experimental Psychology: Human Perception and Performance, 28, 628-639] found no evidence for an auditory warning signal advantage and showed that at brief foreperiods a signal in the same modality as the target facilitated responding more than a signal in a different modality. They accounted for this result in terms of the modality shift effect, with the signal exogenously recruiting attention to its modality, and thereby facilitating responding to targets arriving in the modality to which attention had been recruited. The present study conducted six experiments to understand the cause of these conflicting findings. The results suggest that an auditory warning signal is not more effective than a visual warning signal. Previous reports of an auditory superiority appear to have been caused by using different locations for the visual warning signal and visual target, resulting in the target arriving at an unattended location when the foreperiod was brief. Turatto et al.'s results were replicated with a modality shift effect at brief foreperiods. However, it is also suggested that previous measures of the modality shift effect may still have been confounded by a location cuing effect.     

Learning a procedure from multimedia instructions: The effects of film and practice

College students were taught to build a model helicopter from an assembly kit. Their instructions consisted of a narrated film (one viewing or two), hands-on practice using a model as a guide (one building or two), or a combination (see film first, build second; or build first, see film second). Performance on assembly from memory was assessed either immediately or after a 1-week delay. Both structural and functional measures were used. (A new structural measure is introduced here.) Performance was best immediately for groups who had hands-on practice, either twice, or in conjunction with a film. After a week, the group who practised first and saw the film second performed significantly better than all others. A theoretical framework, based on multimedia concept formation, is briefly presented to account for the results. In order for lasting concepts to be formed in memory, a precedence is suggested: motoric elements with their accompanying mental components should be put in first, followed by visual, followed by linguistic.     

The effects of empathic instructions upon donating behavior: Sex differences in young children

First-grade children were given either empathy instructions (in which they were told to imagine themselves in the target person's place) or neutral instructions (in which they were told to listen to what the target person did). For half the subjects, the target person was of the same sex; for the other half, the target person was of the opposite sex. Subjects were then given a chance to anonymously donate money to the target child, who was presented as being in need. Liking for the target child, subject's perceptions of the target child's emotional state, and subjects' report of their own emotional states were also assessed. Empathic instructions increased donating behavior for males, but not for females. Accuracy of perception of the target person's state was generally high. Self-reports of emotional states congruent with that of the target tended to be associated with increased donating behavior only for males, but these self-reports were greater for females than males, and greater for both sexes with same-sex target persons. Liking also was enhanced by gender similarity. These results are discussed in terms of a proposed relationship among empathy, prosocial behavior, sex, and age.We wish to express our gratitude to the staff and students of Wannamaker and North Fairview Elementary Schools of Topeka, Kansas, for their assistance in carrying out this research, and also thank C. Daniel Batson for his helpful suggestions and comments.     

The Representationalism versus Relationalism Debate: Explanatory Contextualism about Perception

There are two very different ways of thinking about perception. According to representationalism, perceptual states are representations: they represent the world as being a certain way. They have content, which may or may not be different from the content of beliefs. They represent objects as having properties, sometimes veridically, sometimes not. According to relationalism, perception is a relation between the agent and the perceived object. Perceived objects are literally constituents of our perceptual states and not of the contents thereof. Perceptual states are not representations. My aim is to argue that if we frame this debate as a debate about the individuation of perceptual states, rather than the nature of perception, then we can reconcile these two seemingly conflicting ways of thinking about perception.     

The effect of instructions on performance in the Wason selection task

The effect of instructions on performance on the standard abstract form of Wason’s selection task was examined. Instructions to determine whether or not the statement is violated did not lead to an increase in correct responding, contrary to previous suggestions that such instructions would induce falsification strategies, but rather to an increase in verification bias. Instructions to determine whether the statement is true or false led to increased variability in performance, supporting the suggestion that such instructions are inherently ambiguous. Thus, the results demonstrate that the form of instructions can have a significant effect on performance in the selection task. Verification bias did better as an explanation of the data than did matching bias, which only fared well when its predictions coincided with those of verification bias. A substantial proportion of the data was unaccounted for by either of these strategies, which is consistent with the findings of a number of other recent studies.     

Rorschach administration: a comparison of the effect of two instructions

The effect of administering the Rorschach Inkblot Method under 2 instructional sets was compared across 19 outcome measures. Sixty healthy participants randomly received either the short instruction "What might this be?" originally developed by Rorschach (1942) and recommended in the Comprehensive System (Exner, 1993), or a long instruction (Killingmo, 1980), which for many years has been the standard instruction in Norway. The short instruction produced significantly more questions to the examiner about the test and more brief protocols R < 14) than did the long one. However, for the traditional summary Rorschach scores no between-group differences were observed for the 2 instructional sets. It is suggested that if future studies of larger clinical and more representative samples demonstrate corresponding results, a more elaborate standard instruction might be preferable.     

Modern robust data analysis methods: measures of central tendency

Various statistical methods, developed after 1970, offer the opportunity to substantially improve upon the power and accuracy of the conventional t test and analysis of variance methods for a wide range of commonly occurring situations. The authors briefly review some of the more fundamental problems with conventional methods based on means; provide some indication of why recent advances, based on robust measures of location (or central tendency), have practical value; and describe why modern investigations dealing with nonnormality find practical problems when comparing means, in contrast to earlier studies. Some suggestions are made about how to proceed when using modern methods.     

Judgements of relative direction: The effect of task instructions on spatial recall

One of the most widely used tasks in the spatial memory literature is the judgement of relative direction (JRD) test. The present investigation examined the hypothesis that standard JRD task demands bias spatial recall. In two experiments, participants' recall of small-scale layouts as measured by standard JRD tests (in which the relationship between objects was employed to establish imagined orientations within the learned scene) was compared with recall as measured by novel JRD tasks. The novel tasks emphasized either the internal front/back and left/right axes of individual objects (Experiment 1) or extrinsic spatial cues (Experiment 2). Spatial recall was found to reflect the reference cues emphasized by the JRD task in Experiment 1 and by the novel task in Experiment 2. The finding that directional judgements tended to reflect a frame of reference aligned with the set of cues emphasized by task demands suggests that the nature of the task employed to test knowledge can have an effect on spatial recall.
