Mental addition in third,fourth, and sixth graders

Research on mental arithmetic has suggested that young children use a counting algorithm for simple mental addition, but that adults use memory retrieval from an organized representation of addition facts. To determine the age at which performance shifts from counting to retrieval, children in grades 3, 4, and 6 were tested in a true/false verification task. Reaction time patterns suggested that third grade is a transitional age with respect to memory structure for addition—half of these children seemed to be counting and half retrieving from memory. Results from fourth and sixth graders implicated retrieval quite strongly, as their results resembled adult RTs very closely. Fourth graders' processing, however, was easily disrupted when false problems were presented. The third graders' difficulties are not due to an inability to form mental representations of number; all three grades demonstrated a strong split effect, indicative of a simpler mental representation of numerical information than is necessary for addition. The results were discussed in the context of memory retrieval versus counting models of mental arithmetic, and the increase across age in automaticity of retrieval processes.     

Simple and complex mental addition across development

Students in Grades 1, 4, 7, and 10 were timed as they solved simple and complex addition problems, then were presented similar problems in an untimed interview. A manipulation of confusion between addition and multiplication, in which multiplication answers were given to addition problems (3 + 4 = 12), revealed evidence for the hypothesized interrelatedness of these operations in memory only in 10th graders. The overall pattern of results suggests a strong reliance on memory retrieval, even in the first-grade group, with discernible time differences when “procedural” knowledge of carrying is required for problem solution. The results were judged consistent with a fact retrieval model which invokes explicit procedural information when problem difficulty is high or when processes like carrying and estimating magnitudes are required. In agreement with several other reports, the overall slowing of performance to larger problems is best explained in terms of normatively defined problem difficulty or associative strength in memory.     

The relationship between vocational interests and job satisfaction: Reconciliation of divergent results

It was hypothesized that congruency of vocational interests with present occupation would be positively related to job satisfaction for long job-tenured employees, and would be unrelated to satisfaction for short job-tenured employees. In two samples of 54 and 47 middle managers, the hypothesis was supported for satisfaction with work and supervision. This differential pattern of correlations may help explain the inconsistent relationship between vocational interests and job satisfaction obtained in past studies.     

The stability of individual differences in behavior across experimental conflict situations

Four experimental conflict situations having theoretical implications have been reported upon with some frequency. The purpose of this study was to compare individual differences on a common measure, response latency, in order to determine the stability of behavior across these four conflict situations using a comparable latency measure. The results of this study do indicate that behavior in experimental conflict studies shows a stability of performance by individual subjects. There are also group mean differences between the four procedures that reflect situational contribution to conflict behavior.     

Antecedents of employees' mental health—The role of career and work satisfaction

It was hypothesized that individual and situational variables, as a whole, will show stronger relationships with work-related attitudes than with mental health indices. Work-related attitudes, on the other hand, were expected to contribute more strongly to mental health than the individual and situational variables. Results obtained from two groups of staff professionals and retail store managers, using primarily questionnaire data, supported these hypotheses. Career and work satisfaction emerged as the strongest contributors to mental health. Situational variables such as job characteristics, supervisory style, and pay related more strongly to the attitudinal variables than to mental health. This pattern suggests that career and work satisfaction may serve as intervening variables in the relationship between situational variables and mental health.     

Emotional responsivity to nonveridical heart rate feedback as a function of anxiety

The purpose of the present investigation was to examine the effects of nonveridical heart rate feedback and anxiety on electrodermal responses and verbal reports to emotionally laden stimuli. Forty-eight female subjects were divided into high and low anxious groups on the basis of their Taylor Manifest Anxiety Scale scores and resting level electrodermal activity. All subjects viewed 10 autopsy slides while hearing continuous auditory tones supposedly representing their own heartbeats. Twenty-four subjects heard the tones increase in rate with slide onset. The other 24 subjects heard no change in rate with slide onset. The high resting autonomic activity group responded with significantly larger electrodermal responses to the heart rate feedback-slide combination than the low resting level autonomic activity group. The high autonomic activity group also reported that the slides were significantly more unpleasant than the low autonomic activity group, particularly those slides accompanied by an increase in heart rate feedback. Implications of these findings for a cognitive-visceral model of emotion are discussed.     

A biographical data analysis of career patterns in engineering

This study focuses on an instrument that appears useful for career guidance or job assignment purposes — the Biographical Data Blank. Responses of three groups of engineers (holding research and development, management, and nonengineering positions) to a life history questionnaire were analyzed. Results indicate that groups could indeed be differentiated using response patterns. In addition, items defining these patterns were related to demands of actual career paths chosen.     

Cross-response mode consistency in risk taking as a function of self-reported strategy and self-perceived consistency

Earlier work (Slovic, Journal of Personality and Social Psychology, 1972, 22, 128–134) has found that consistency in preference for the same stimuli across two response modes, selling price and choice, is only moderate. The present study followed the same procedure and also asked subjects to report the strategies they used to determine their preferences and to state how consistent they usually were in gambling tasks. Greater consistency was found for those (1) who reported strategies for both response modes, (2) whose strategy type matched across response modes, and (3) who perceived themselves as consistent. Strategy differences were also found across response modes. The results were discussed in terms of the usefulness of assessing subjective task interpretation in predicting consistency and for the general desirability of greater idiographic assessment for increased predictability.     

The prediction of political evaluation and voting preference: A multidimensional analysis

Two separate studies, using college students in a political behavior class, tested the relationship between evaluation and voting preferences on the one hand and the dimensions emerging from a multidimensional scaling of similarity judgments for a set of nationally known political figures. Both studies found that political evaluation and voting preferences were highly predictable from three major dimensions underlying political perception. In Study I (n = 64), the subjects' self-ratings of liberal-conservatism yielded individual differences in the predictability of activity and potency from the political dimensions as well as differences in the relationships among evaluation, activity, and potency. In Study II (n = 51), the subjects' own authoritarianism indicated differences in the manner in which political figures were perceived in the multidimensional space.     

Balance,agreement, and attraction in hypothetical social situations

Sixty subjects rated hypothetical P-O-X situations involving two persons and an unspecified but important “thing” for pleasantness, tension, and consistency. The situations varied in terms of whether P and O liked or disliked each other and whether P and O agreed or disagreed regarding X. Half of the subjects rated eight situations used by Gutman and Knox (Journal of Personality and Social Psychology, 1972, 24, 351–357) in which a unit relation was induced between P and O by describing them as necessarily having to continue interacting with one another in the future. The other half of the subjects rated situations that were identical to those of the unit condition, except that stipulation of continued interaction was omitted, so that no unit relation was specifically induced. Results showed that preferences for agreement and attraction were stronger for pleasantness and tension ratings than for consistency ratings, while the preference for balance was stronger for consistency ratings than for pleasantness and tension ratings. When no unit relation was specified, the balance preference increased, whereas the attraction preference decreased. Moreover, the effect of attraction decreased more from the unit to the no unit condition for pleasantness than for tension ratings and more for tension than for consistency ratings. The results underscore the need to consider the influence of both the described characteristics of hypothetical social situations and the type of dependent measure employed on the weighting of preferences for balance, agreement, and attraction.     

Androgyny,sex-typing,and the perception of masculinity-femininity in handwritings

Sex-typed and androgynous subjects rated the similarity of handwritings on masculinity-femininity and also rated the writings on an absolute scale of masculinity-femininity. The variances of sex-typed subjects' ratings were significantly higher than those of androgynous subjects, indicating that sex-typed subjects differentiated more along the dimension. Sex-typed subjects also agreed more highly with other raters and among themselves than did androgynous subjects. Multidimensional scaling of similarity ratings—using nonmetric multidimensional scaling (Kruskal, 1964; Shepard, 1962), and INDSCAL (Carroll & Chang, 1970)—showed interpretable dimensions along which subjects perceived masculinity-femininity. Further scaling solutions indicated again that sex-typed subjects differentiated more strongly along the dimension of masculinity-femininity and weighted the dimension more highly in making their similarity ratings. The data supported the hypothesis that subjects who monitor their own behavior on a given dimension are more sensitive to cues in others relating to that dimension.     

Race versus belief about race as determinants of attraction: Belief prejudice and two kinds of race prejudice

An experiment was conducted to assess the effects of actual racial membership versus similarity of beliefs about racial issues on interpersonal evaluations. Prejudiced and unprejudiced White male students observed a videotaped interaction of two Black and two White male actors discussing racial issues and then evaluated the actors on several scales. One White and one Black actor took a conservative stand on racial issues, and the other White and Black pair of actors took a liberal position. Results from the ratings showed strong belief prejudice effects. Prejudiced subjects were attracted to conservative actors while unprejudiced subjects were attracted to liberal actors. Additionally, there were two kinds of race effects. Prejudiced subjects preferred White to Black actors, but unprejudiced subjects showed a reverse bias, preferring Black to White actors. A tentative explanation for this unusual finding was proposed.     

Psychological differentiation and the evaluation of juridic information: Cognitive and affective consequences

The cognitive and evaluative involvements of field dependence-independence in the processing of available information were examined in two experiments. In Experiment 1, ninety-six female undergraduates were assigned to field-dependent and field-independent conditions (via a median split on Embedded Figures Test scores). Half were given information about the trial of a man accused of attempted manslaughter that was suggestive of guilt; the other half received information suggestive of innocence. They were asked to indicate their confidence in the guilt or innocence of the defendant, and to recall arguments from the information they received. Field-dependent subjects were significantly more extreme in their confidence judgments, particularly in the exonerating conditions. They also showed nonsignificantly poorer recall. In Experiment 2, forty-eight subjects from Experiment 1 were given arguments biased in the opposite direction of their original sets. Field-dependent subjects were significantly more likely to shift their confidence judgments and report discomfort when the new information suggested innocence, and to underrecall new information when it suggested guilt. Field-dependent subjects again showed poorer recall. The results of both experiments were discussed in terms of their support for a field-dependence value bias and encoding deficiency.     

The Missouri Children's Picture Series: Correlates of the aggression scale in normal fourth-grade males

Missouri Children's Picture Series (MCPS) Aggression scale scores and four more traditional measures of aggression were intercorrelated for 40 normal fourthgrade boys. Results indicated that the MCPS Aggression scale must be viewed as a highly specific instrument which has little if any usefulness in a public school setting. In addition, the failure of the five aggression measures to be interrelated significantly suggests that aggression may be a highly situational response, with children varying in the modality through which they are able to express aggressive feelings and motives.     

Equity,equality, and the protestant ethic: Allocating rewards following fair and unfair competition

Female undergraduates scoring high and low on the Mirels-Garrett Protestant Ethic (PE) Scale divided a fixed reward between themselves and a co-worker following competition on a clerical task. Half the subjects were told that they had either won or lost in fair competition. The remaining subjects were told they had either won or lost because of an error that gave a favorable advantage to one of the performers. When the competition was fair, high PEs distributed the rewards available according to an equity norm, keeping more than half when they won and less than half when they lost. When the competition was unfair, high PEs attempted to reestablish fairness by compensating the performer with the unfair disadvantage. However, low PEs kept approximately half the reward regardless of fairness and regardless of whether they won or lost.
