Imagery ability and the identification of hands: A chronometric analysis

In a replication of Cooper and Shepard's (1975) study of hand recognition, it was found that individual differences in imagery ability had a significant influence on reaction times to such stimuli (Experiment 1). However, it was found (Experiment 2) that individual difference effects were only seen if prior instructions to use imagery were given to the subjects.     

Statistical inference in personality research

Statistical significance, by itself, is not a sufficient condition for claiming that a hypothesis has been supported. Constructive replications are considerably more important. Unfortunately, classical (Fisherian) statistics are not easily adapted to sequential research strategies; their focus is the single experiment. For this reason, statistically significant results may be meaningless while a particular sequence of nonsignificant results may be quite important. Advice on how to overcome some limitations of classical statistical procedures is given, along with a compendium of “do's and don't's.”     

Economic deprivation and the quality of parent-child relations: A trickle-down framework

The trickle-down model of economic activity proposes that changes in economic activity permeate downwards from incentives or disincentives to business, which affect business income, investment, employment, and the absolute and relative economic deprivation of the poor. Within an extended trickle-down framework, this paper examines how these effects trickle further downwards to influence the quality of parent-child relations. Two cases are examined. First, deprivation is discussed as it trickles down to affect the parental image conveyed to children, and in turn perceptions od parents are examined as these predict children's problem behavior. Second, deprivation is discussed as it trickles down to affect parents' psychological well-being and child-rearing capabilities, particularly as manifested by the incidence of child abuse and neglect. The evidence to date converges to indicate that children in general are not necessarily aware of or sympathetic to the plight of those under economic strain. Economic deprivation may exacerbate conflict in the family, diminish children's perceptions of parents, and give rise to problem behavior in boys. Evidence also suggests that deprivation may be an antecedent of poor psychological well-being in adults and child abuse. Possibilities for a “bubble up” model of economic activity are explored together with directions for further research.     

Memory for movement: Interaction of location and distance cues and imagery ability

The present experiments examined the role of imagery ability in recall of either the terminal location or the distance of a preselected horizontal linear movement following changes in the recall starting position. Subjects were selected on the basis of their scores on a shortened version of the Betts Questionnaire upon Mental Imagery (Betts Q.M.I., Sheehan 1967). Both high and low imagers were assigned to one of four groups, HIL, LIL, HID, LID, the last letter indicating the movement cue (terminal location or distance moved) to be recalled. Recall of the appropriate movement cue from one of four new recall starting positions occurred after either a 5-sec or 30-sec unfilled retention interval. Analysis of constant error indicated all groups were unable to recall the specified movement cue independent of the other source of information, even when subjects were given explicit instructions to utilise an imagery strategy. The data corroborate our earlier findings that memory for self paced movements is based on an interaction of location and distance cues derived from the criterion movement.     

Employee self-esteem: A review of the literature

Theories and empirical findings about self-esteem derived from the work role and its activities are reviewed. First, self-esteem is defined and problems inherent in its measurement are discussed. Theoretical perspectives relating self-esteem to the work role and activities are then outlined. Problems of a methodological nature, common to most of the evidence, are highlighted prior to reviewing the intrinsic and extrinsic job characteristics which influence self-esteem. The evidence pertaining to the moderating effects of chronic global self-esteem on such relationships is incorporated. The attitudinal and behavioral correlates of high employee self-esteem are then presented, followed by the influence of chronic self-esteem level on occupational choice. Suggestions are made for future research in line with the methodological and conceptual problems encountered.     

Artifact and Barber's model of hypnosis: A logical-empirical analysis

Two studies examined the relevance of artifact to Barber's model of hypnosis. Study I analyzed subjects' perceptions of instructions employed by the paradigm and demonstrated strong social pressure in the model's task motivational set not present in its standard set of hypnotic induction instructions. Study II coped with the artifact by applying the standard methodology of the model but employing a set of modified hypnotic instructions equivalent in constraint to the task motivational set. Results for 88 subjects indicated a possible behavioral consequence of the artifact variable involving an interaction between type of instruction and ease of hypnotic test item; individual differences in suggestibility also appeared to discriminate conditions with respect to the artifact in question. Collectively, results indicate that the major inference drawn from the paradigm regarding the expendability of the concept of trance should be accepted with caution.     

Identification with film characters, covert aggressive verbalization, and reactions to film violence

To determine some conditions governing the aggressive aftereffects of identification with aggressive film characters, men were first angered by a confederate and then exposed to a film clip of a violent boxing match. Subjects instructed to identify with the winner of the prize-fight were subsequently more aggressive toward the confederate than subjects instructed to identify with the loser or subjects not asked to identify with a film aggressor. Apparently, viewers must perceive their identificand incur reinforcement for his aggression before they become more aggressive themselves. However, requiring subjects to make implicit aggressive verbalizations during the film completely eliminated any aggressive aftereffects of identification. This finding was opposite to prediction and suggested that covert verbalization interfered with subjects' ability to make the vicarious aggressive responses which mediate increased subsequent aggression.     

Power and speed components of individual differences in letter matching

Several previous studies have reported a correlation (typically around −.30) between standardized verbal ability test scores and name identity minus physical identity reaction times (NI-PI) in a letter-matching task. This correlation has usually been thought to reflect the mutual dependence of both measures on long-term memory access time. The present research was designed to assess Carroll's (1981) suggestions that: (a) NI — PI may not be the optimal formula for predicting standardized test scores from letter matching data, and (b) NI — PI may actually be related to the speed rather than the power component of standardized tests. Fifty-one subjects previously tested with a standardized reading test participated in letter-matching and word-reading tasks. The latter tasks required subjects to read words and specially constructed pseudowords. Power and speed measures were derived from the word-reading tasks and the standardized test on theoretical grounds (and supported by a principal components analysis). The results supported both of Carroll's contentions. NI — PI reaction time was related more to speed than power and the NI — PI statistic (as usually used) was not the optimum formula for predicting standardized test scores.     

The retention of nouns,adjectives, and verbs of sentences

This research compared the retention of nouns, adjectives and verbs of sentences. A model of the structure underlying the retention of sentences and in which deep structure constituent propositions are hierarchically related, was used to make predictions concerning the retention of these word classes. The model was not supported by the data and it was determined that latencies to recognize the words of a previously presented sentence were the same for all classes of words. This result indicated that for recognition (but not necessarily for other memory tasks), each word of a sentence is seperately or equally accessible (as long as inter-word imagery is the same). However, a further experiment showed that, although word class is not a variable, the image-arousing capacity of a word is. Latencies and error rates were much lower for high-imagery words than for low-imagery ones. The findings on error rates in recognizing words were interesting and pointed to a different model where the meaning representations and syntatic functions of words have an active role in sentence retention.     

A category theory approach to cognitive development

The category theory concept of a commutative diagram is used to construct a model of the way in which symbolic processes are applied to problem solving. The model provides for a relationship between symbolic processes and the problem which depends on structural isomorphism and consistency, but is independent of similarity between symbol elements and problem elements. It is then shown that several different levels of thought can be distinguished within the basic model. More information is needed to assign symbolic processes to a problem in a consistent way with higher-level thought processes than with lower-level processes. These information-processing requirements permit the approximate age of mastery of each level to be predicted, thereby offering an alternate theory of cognitive developmental stages. Two experiments designed to test the theory are reported.     

Can group differences in hemispheric asymmetry be inferred from behavioral laterality indices?

A large and often contradictory literature purports to demonstrate different patterns—or at least different degrees—of hemispheric specialization across various groups of people. Schizophrenics, dyslexies, stutterers, musicians, Orientals, Jews, and many other groups have been alleged to display idiosyncratic laterality patterns. An examination of this literature reveals three important problems. First the groups concerned are rarely homogeneous. This makes it difficult to know which group characteristics, if any, are responsible for the observed differences. Second, most behavioral laterality indices are of low reliability making group differences highly unstable. Third, the validity of many behavioral laterality indices has not been substantiated. Because of these problems, it is concluded that caution should be exercised in using and interpreting laterality measures to make between-group comparisons. For now at least, group differences in laterality cannot be inferred.     

Generality of persistence: The role of stimulus and response factors in persistence to punishment

Previous research has shown that intermittent punishment of a response increases its persistence to continuous punishment and that intermittent punishment training in one situation produces persistence to continuous punishment in other situations. Experiment 1 showed that as long as the instrumental response and punishing stimulus were held constant from intermittent to continuous punishment marked differences between these situations had no decremental effect on persistence. Experiment 2 showed that intermittent punishment training of one response resulted in substantial persistence to continuous punishment of a different and apparently incompatible response and that such response change had no more than a marginal effect on persistence. The results were seen as requiring some revision to the traditional conditioning-model interpretation of persistence to punishment.     

Reading skills of hearing and congenitally deaf children

The present study examined the nature of reading skills in congenitally deaf and hearing children 7–19 years of age. Deaf children were drawn from oralist and total communication programs. A visual detection task was designed to assess the extent of phonological coding and chunking used in reading a story of various degrees of syntactic, semantic, and orthographic complexity. The results provide evidence that (1) like hearing children, deaf children tend to use orthographic regularities in their reading: (2) there is no relation in the deaf child's performance between sensitivity to orthographic regularities and the type of communication method used in training; and (3) hearing and deaf readers use qualitatively similar psycholinguistic strategies in their processing of a story.     

Memory and intelligence: Age and ability differences in strategies and organization of recall

Proficiency at organizing information for recall is one aspect of memory functioning which could be expected to be related to intelligence, or general ability. Comparisons of children of average and of superior ability (Kuhlmann-Anderson scores) in a multitrial free-recall learning task confirmed this prediction: Both level of recall and amount of sequential organization were significantly higher for the superior ability groups. Mental age definitions of intelligence imply that equivalent performance by children of different chronological ages will be based on qualitatively similar cognitive processes. This assumption was not confirmed. Age-related changes in mnemonic strategies were not associated with ability-related differences in recall or organization. Some features of memory development are more dependent on age, whereas others are more dependent on ability. The latter may be best explained in terms of production inefficiency (Flavell, 1970).     

Self-assessment and task performance

The present study tested the idea that the amount of effort expended in task performance is a function of the amount of uncertainty in one's ability level the resulting outcomes are expected to reduce. Two determinants of expected uncertainty reduction were manipulated: prior uncertainty about one's ability level and the diagnosticity of the task. Subjects first performed an initial task and then received fictitious feedback to manipulate their prior uncertainty. To induce low uncertainty, the feedback implied that the subjects are highly likely to have either low, intermediate, or a high level of ability. To induce high uncertainty, the feedback implied that the various ability levels were equally probable. Subjects then performed a task whose perceived diagnosticity regarding the ability under consideration was varied. As expected, subjects who were highly uncertain about their ability level performed better than subjects who were relatively certain they possessed either low, intermediate, or a high level of ability. Performance also improved with task diagnosticity, and the effect of task diagnosticity on performance was more pronounced when prior uncertainty was high than when it was low. Past research on the relationship between prior feedback and subsequent performance was discussed in light of the present results and a self-assessment model of achievement behavior.     

Personality correlates of adjustment in isolated work groups

Twenty-five personnel from two Antarctic research stations spent the austral winter (February-October) confined in small, isolated stations located on the Antarctic ice cap. At the end of this confinement, they completed two questionnaires. The first asked about alcohol and marijuana use and self-rated adjustment to the living conditions; it also asked for nominations of others with whom each would most like and least like to spend another Antarctic tour. The second questionnaire was a recently developed personality inventory. Personality scale scores were correlated with self-rated adjustment and peer nominations. The results were consistent with previous research, and indicated that adjustment was a function of narrow interests and a low need for stimulation. More importantly, the findings also demonstrated that personality inventories are useful for predicting adjustment to working conditions in such isolated settings.     

Relationship of age,sex, and educational groups to career decisiveness

Five educational groups, composed of a total of 369 students, ranging from high school freshmen to college juniors, were administered the Career Decision Questionnaire, a scale designed to measure antecedents of educational-vocational indecision. It was determined that age was an extremely important factor in career decidedness, sex was not an important variable in determining decidedness, and certain educational groups stood out as significant factors associated with level of career decisiveness. Students enrolled in career orientation classes were clearly more undecided than students enrolled in 12th-grade vocational classes, college preprofessional classes, and more general groups of high school students. Interaction among variables and the measurement of career decidedness are discussed, with applications for counseling considered.     

A scale for the measurement of role-playing ability

A convenient paper-and-pencil measure of acting or role-playing ability was constructed, validated, and compared to a variety of theoretically and methodologically similar and dissimilar scales, including a specially designed improvisational situations test. Results indicate that the new scale provides both a reliable and valid screening device for the study of role-playing ability.
