On the ethics of psychological research

Three philosophical positions on the nature of ethics were examined and contrasted within the context of psychological research: (a) teleology, which involves the balancing of the costs and benefits associated with an action as a means of developing general ethical rules; (b) deontology, which involves the rational adherence to rigid, universal rules that hold irrespective of the situation or consequences; and (c) skepticism, which involves denying the ability to apply universal rules and asserting the individuality of moral codes. Two experiments investigated the degree to which judgments of the ethicality of psychological research are affected by the consequences of the research and judge's ethical ideology. Subjects judged experiments that investigated obedience to an authority as generally less moral and more threatening to the participants' dignity and welfare when the proportion of total obedience was high rather than low. The proportion of participants (10 vs 40%) who were described as “psychologically upset” by the research did not affect moral judgments. These results were obtained across two different obedience situations (Milgram's study and a Watergate study) and different subject populations (high school and college students, males and females). As suggested by philosophers, a judge's ethical ideology determined how the perceived benefits and costs of the research were correlated with moral judgments. Teleologists weighed scientific benefits heavily, deontologists weighed participants' costs heavily, and skeptics weighed both heavily.     

The relationship of moral judgment, self-awareness, and sex to complicance behavior

Sixty male and sixty female college students, representing three of Kohlberg's stages of moral judgment, were exposed to a complicance situation in which their personal count of a series of metronome clicks was contradicted by a unanimous group. Group differences were either one or two steps from veridical. For half of the subjects self-awareness was experimentally increased. The results indicated that subjects in moral judgment Stages 3 and 4 complied significantly more than Stage 5 subjects. The self-awareness manipulation produced a complex pattern of results in the form of a three way interaction with moral judgment and type of compliance. Finally, sex differences in compliance behavior were significant, with females complying more than males. The results were discussed in terms of a cognition-behavior relationship.     

Young children's understanding of displaced aggression

According to previous research, young children do not understand displaced aggression. The present study examines the early phases of the understanding of the causes of moderately and extremely displaced aggression. Preschool and kindergarten children (3 to 5 years of age) viewed eight videotaped episodes of displaced aggression. Their comprehension of this aggression was assessed by means of open ended questions and forced choice picture selections. By age 5 most children had some understanding of displaced aggression, but this understanding was not complete. The early understanding revealed in the present study may be due to the use of short, simple realistic videotaped episodes appropriate for the limited processing abilities of young children. Extreme displacement was not more difficult to understand than moderate displacement.     

Children's reasoning about the causes of human behavior

Three studies examined young children's ability to predict how certain internal and external conditions affect behavior. Study 1 included 136 children from early preschool, late preschool, kindergarten, and second grade. A forced choice procedure revealed that even the youngest group could predict the effect of various internal-personal causes (e.g., interest, intelligence) and external-situational causes (e.g., rewards, adult pressure). Older preschoolers and second graders considered these internal causes more powerful than these external causes. With the same procedure, in Study 2 the 16 preschoolers predicted that both physical characteristics (e.g., strength, energy level) and the internal-personal characteristics of Study 1 affect performance in athletic activities. In addition, they considered the physical causes more important. Study 3 examined more complex types of causal reasoning. Younger preschoolers responded randomly but older preschoolers combined two causes to create a greater effect than one cause and used an external cause to enhance, rather than discount, an internal cause. The discussion focused on the cognitive development underlying developmental differences in the ability to predict behavior on the basis of one or two causes.     

Hemispheric function and linguistic skill in the deaf

The nature of hemispheric processing in the prelingually deaf was examined in a picture-letter matching task. It was hypothesized that linguistic competence in the deaf would be associated with normal or near-normal laterality (i.e., a left hemisphere advantage for analytic linguistic tasks). Subjects were shown a simple picture of a common object (e.g., lamp), followed by brief unilateral presentation of a manually signed or orthographic letter, and they had to indicate as quickly as possible whether the letter was present in the spelling of the object's label. While hearing subjects showed a marked left hemisphere advantage, no such superiority was found for either a linguistically skilled or unskilled group of deaf students. In the skilled group, however, there was a suggestion of a right hemisphere advantage for manually signed letters. It was concluded that while hemispheric asymmetry of function does not develop normally in the deaf, the absence of this normal pattern does not preclude the development of the analytic skills needed to deal with the structure of language.     

Social insulation, self-complexity, and social attraction: A theory chain

In a theory chain extending Byrne's theory of social attraction, links are described between breadth of social interaction and complexity of the self-concept as well as between complexity of the self-concept and social attraction. In the first series of studies, it was shown that communication-handicapped adolescents and physically handicapped children, as well as terminally ill patients, indicate lower self-complexity. In a second series of studies, it was found that persons with more complex self-concepts identify more closely with others, perceive themselves as more similar to objectively dissimilar others, and are more popular sociometrically.     

Relative efficacy of different encoding structures and judgment topics in a cued-recall task

Existing research on the relative efficacy of the self as an encoding structure applies more to the self as an object than as a cognitive structure that guides the organization of incoming information. In order to provide a task that would be more directly relevant to encoding, subjects were asked to watch an interview of a resident assistant (RA) candidate by the housing department and to attend throughout to how similar the candidate's presentation was to the one they themselves or a typical RA would have given in the situation. Furthermore, judgments of similarity were divided into personality, ability, and nonverbal style. The dependent variable was a surprise cued-recall task, administered 20 min after the videotaped interview had ended. Consistent with prediction, subjects instructed to encode from a self-perspective exhibited better recall than those instructed to encode from a typical RA perspective. Also, as predicted, subjects who judged personality or ability similarity recalled more of the interview than those who judged nonverbal style similarity. Enhanced recall from the self-encoding perspective was consistent across all three types of judgments (personality, ability, nonverbal style), suggesting that the self is an efficient processing structure across a variety of diverse judgment topics.     

A disconfirmation of the quantitative identity-quantitative equivalence sequence

Sixty-four kindergarten children received tests of quantitative identity and quantitative equivalence for the conservations of number and continuous quantity. Two types of identity trials were included: a standard version using a single stimulus, and a modified version which paralleled the equivalence task in its use of two stimuli. In addition, half of the children were asked two questions on each trial (one preceding and one following the transformation), whereas half were asked only the post-transformation question. Neither the number of stimuli used nor the number of questions asked had any effect on performance. In contrast to some previous reports, tests of quantitative identity were no easier than tests of quantitative equivalence. It was concluded that the identity-equivalence décalage, if it exists at all, is less important than previous authors have claimed.     

Children's and adults' integration of information about noise and interest levels in their judgments about learning

This study examined developmental changes in the understanding of distractibility. It focused on how information about both interest level and noise level are used to form judgments of how many items a hypothetical child would learn. A total of 112 subjects from grades K, 2, and 5 and college age used a rating scale to judge the amount of learning in situations generated by a factorial combining of three levels of interest and three levels of surrounding noise. Children at all ages, even kindergarteners, used both noise and interest information in making their judgments. Interest level influenced judgments much more than noise level at all ages, but this imbalance waned somewhat with increasing age. The rules for combining noise and interest were more complex at the older ages. The discussion focused on interpretations of the subjects' belief that interest level heavily influences attentiveness.     

An examination of the Fishbein-Ajzen behavioral-intentions model's concepts and measures

The Fishbein-Ajzen behavioral-intentions model is designed to represent the effect of attitudes and subjective norms on behavioral intentions. The model has been used in a variety of contexts, and evidence for its validity flows largely from its generally good performance in predicting behavioral intentions. However, the manner in which these concepts are defined and operationalized appears to make it inappropriate for those seeking to distinguish between personal and normative reasons for engaging in a behavior. Additional problems were found in the hypothesized relationship between the more global normative construct and its underlying components.     

Socially mediated fear reduction in rodents: Distraction,communication, or mere presence?

Two studies investigated why the presence of conspecifics reduces open-field fear. In Experiment 1 rats paired with another experimentally naive rat were not less fearful than alone controls. However, rats paired with a partner who had been preexposed to the open field exhibited fewer fear responses than alone controls. Since preexposed companions appeared to initiate more social interactions than nonpreexposed companions, it was argued that the preexposure effect could be the result of preexposed companions distracting actor rats from threatening stimuli. Experiment 2 tested this explanation by pairing socially sated or socially deprived rats with a socially sated or socially deprived companion. In accord with a distraction hypothesis, pairing two socially deprived rats produced the greatest fear reduction effects and also led to more social interaction than pairing socially sated rats. Alternative explanations involving conditioning and communication are discussed.     

Helping as a function of empathic responses and sociopathy

The present study reports two experiments which investigated helping as a function of empathic anxiety (anxiety in response to modeled distress) and individual differences in sociopathic tendencies. The first experiment concerned the effects of empathic anxiety, sociopathy, and perceived similarity/dissimilarity to a distressed person on helping. As predicted, subjects who experienced high levels of empathic anxiety helped more than subjects who experienced low levels of empathic anxiety. High sociopathic subjects experienced lower levels of empathic anxiety and helped less than did low sociopathic subjects. However, a path analysis disclosed that sociopathy's relationship to helping was not due to (or mediated by) empathic anxiety. The similarity manipulation did not influence empathic anxiety or helping. In the second experiment, subjects were classified as primary or secondary sociopaths (based on their levels of trait anxiety). As in the first experiment, empathic anxiety and sociopathy were significantly related to helping. Primary sociopaths displayed less empathic anxiety than secondary sociopaths, but the two groups did not differ in their willingness to help. Thus, in neither study could the sociopath's behavior be explained by empathic anxiety. The discussion concerned empathy as a mediational variable in helping and the role of personality variables in helping. A post hoc explanation of the sociopath's behavior, based on Schwartz' theory of the characteristics of helpers, was proposed.     

Behavioral thresholds for tones during infancy

An adaptive up-down tracking procedure was used in combination with a visually reinforced head turn response to examine auditory sensitivity for 500, 2000, and 8000-Hz tone bursts in infants 6 to 18 months of age. Six- and 10-month-old infants were tested with headphone presentation of stimuli, while 10-, 14, and 18-month-olds were tested in sound field. Infant threshold estimates for both headphone and sound field were within 15 dB of adult comparisons for all frequencies and age groups. Six-month-olds were significantly less sensitive to the 8000-Hz tone than to either of the lower frequency stimuli, but older infants demonstrated approximately equal sensitivity for all three frequencies tested.     

An empirical investigation of self-esteem as a composite construct

Three measures of chronic self-esteem, plus four measures developed to assess situational components of self-esteem (task-specific self-esteem and social self-esteem), were administered to 238 undergraduates at a large, urban university and a community college in the southeastern United States. Evidence for a composite construct of self-esteem was found. Results also indicate task-specific self-esteem correlates as high as .42 (p < .01) with chronic self-esteem and as high as .76 (p < .01) with social self-esteem. Task-specific self-esteem was found to be a better predictor of grade point average than chronic or social self-esteem. Suggestions are made for further research on the situational components of self-esteem to extend current findings.     

Interpersonal congruency,attitude similarity,and interpersonal attraction

To examine relationships among interpersonal congruency, attitude similarity, and interpersonal attraction, the present study required pairs of subject to rate their attraction to each other in response to two proportions of similar attitudes orthogonally varied with two treatments of interpersonal congruency. Findings showed that attitude similarity determined attraction when congruency was uncontrolled, but that similarity and attraction were unrelated within the two congruency treatments. Additional correlational analyses suggest that different judgments of the accuracy of other's perceptions of oneself accompany previous findings on attitude similarity and attraction, and it is proposed that interpersonal attraction may be understood in terms of stabilizing processes postulated by the theory of interpersonal congruency.     

Effects of initial success or failure in a stressful or relaxed environment on subsequent task performance

Forty male and 40 female undergraduate subjects worked on anagram problems in either a stressful or a relaxed environment after having experienced either success or failure on a similar task. Internal arousal, which was expected to be minimal following success in a relaxed setting and maximal following failure in the stressful environment, was assumed to bear an inverted U-shaped relation to performance. Consistent with the implications of these assumptions, achievement in a stressful setting was lower following initial failure than following initial success, while initial failure in a relaxed environment facilitated subsequent performance. The interpretation of these results was supported by the effects of the experimental variables on indirect measures of arousal as well as by the relationship between direct measures of arousal and task performance. In addition, the achievement of female subjects tended to be facilitated by failure while the performance of males was consistently debilitated by it.
