Correlates of Team Success in Higher Education

Summary

An attitude questionnaire was filled out by 75 undergraduates who subsequently evaluated a hypothetical male convict's responses to the same survey—the convict's attitudes being either 10% or 90% similar to each S's own views. Ss then made judgments of the convict's emotional maturity, sense of personal responsibility, and control of violent impulses, as well as how much they would like him as a person and how willing they would be to recommend him for parole. The results indicated that attitudinal similarity to the convict was associated with significantly more positive evaluations of him on each of the five response measures. It was suggested that attitudinal similarity to a convict could be a biasing factor in judgments of whether or not the convict should be paroled.     

The effects of age and set size on the fast extraction of egocentric distance

ABSTRACT

Angular direction is a source of information about the distance to floor-level objects that can be extracted from brief glimpses (near one's threshold for detection). Age and set size are two factors known to impact the viewing time needed to directionally localize an object, and these were posited to similarly govern the extraction of distance. The question here was whether viewing durations sufficient to support object detection (controlled for age and set size) would also be sufficient to support well-constrained judgments of distance. Regardless of viewing duration, distance judgments were more accurate (less biased towards underestimation) when multiple potential targets were presented, suggesting that the relative angular declinations between the objects are an additional source of useful information. Distance judgments were more precise with additional viewing time, but the benefit did not depend on set size and accuracy did not improve with longer viewing durations. The overall pattern suggests that distance can be efficiently derived from direction for floor-level objects. Controlling for age-related differences in the viewing time needed to support detection was sufficient to support distal localization but only when brief and longer glimpse trials were interspersed. Information extracted from longer glimpse trials presumably supported performance on subsequent trials when viewing time was more limited. This outcome suggests a particularly important role for prior visual experience in distance judgments for older observers.     

Developmental Changes in Young Children's Spatial Memory and Language in Relation to Landmarks

Two experiments investigated how young children and adults understand whether objects are by a landmark and remember their locations. Three- and 4-year-old children and adults were asked to judge whether several blocks were by a landmark. The blocks were arranged so that their absolute and relative distances from the landmark varied. Later, the blocks were removed, and participants were asked to place them in their original locations. All ages relied on relative distance between objects and a landmark when making by judgments; however, older children and adults showed systematic judgments. Relative distance also affected block placement, and systematicity increased across development. Children's understanding of the relative nature of by and their ability to remember locations precisely increased during the preschool years, indicating developmental changes in the adaptive combination of location cues for spatial language and memory.     

Relation of Economic and Social Conditions to Voting Behavior in Iowa, 1924–1936

Summary

Using a three-variable design, this study investigated conformity to male and female group pressures among Chinese and American male college students. Methodologically, it departed from traditional group pressure studies in a number of ways: (a) the study was conducted outside the psychological laboratory where demand characteristics of the situation were believed to resemble college life conditions more closely, (b) it utilized changes in personal opinions about beliefs rather than perceptual judgments, (c) it employed unobtrusive, as well as conventional, means of measuring conformity. Another major difference was that S presented his opinion prior to those of the confederates who expressed contradictory opinions to those of S. Five confederates, all male or all female were used. S and confederate opinions and degree of strength of opinions were assessed on six controversial issues. Latency between hearing the controversial statement and S's announcing his opinion was recorded. When S and all confederates had made their statements, S and confederates were permitted to alter their earlier stated opinions or the degree of strength of their opinions. It was found that Chinese Ss increased their hesitancy to respond, from the first to sixth issue, to a greater degree than did Americans. Hesitation for all Ss was longer in the presence of male confederates than in the presence of females. Americans made greater shifts of opinion after the group pressure experience, but Chinese made a greater number of shifts. Americans showed a far greater tendency toward anticonformity than did Chinese.     

The Effect of Self-Imposed Brevity on the Structure of Dyadic Communication

Differences between concise and natural communications in problem solving were investigated by comparing the communications generated by pairs of S s asked to use as few words as possible with the communications by pairs of S s of whom no such request was made. Sixteen male pairs and 16 female pairs, all undergraduate students, were tested. Two modes of communication were used: voice and teletypewriter. An analysis of message function revealed that when S s tried to be brief, they used a larger percentage of messages concerned with the exchange of information and lower percentages of messages that dealt with the rate of communication, judgments, and feedback than under the natural condition. An analysis of parts of speech revealed that those S s who restricted their communications used higher percentages of nouns and adjectives and lower percentages of pronouns, verbs, prepositions, interjections, and articles than did S s who did not restrict their communications. Most of these findings held for both modes of communication.     

The effects of binocular and motion-generated information on the perception of depth and height

The perception of distance and size in the presence of optical gradient information was investigated under four viewing conditions—binocular view with and without head motion, and monocular view with and without head motion. Subjects (60 adults) matched distance intervals (from 15 to 127 cm) and heights of a target triangle (from 5 to 15 cm) by adjusting the length of a metal tape. Both linear and power functions were fitted to each individual’s distance judgments, and the competing perceptual models were compared. For both models, it was found that binocular information was sufficient to specify relative, but not absolute, distance, that monocular information was sufficient to specify an orderly relation between target distance and judgment but not absolute distance, that average error was less in the binocular conditions, and that perceived distance was not affected in either condition by the addition of head motion. The analysis of size judgments revealed that monocular and binocular judgments did not differ, that matches made with and without head motion did not differ, and that, in all conditions, matches exceeded target heights by an average 30% to 40%. Judged size was also analyzed as a function of target distance. In all conditions but monocular view with head motion, the effect of distance was to increase size judgments. The distance judgments support the hypothesis (Purdy, 1958) that the binocular stimulus carries information that the monocular stimulus does not; they fail to support the hypothesis (Gibson, 1966) that observer motion adds information to the static stimulus. The size judgments support neither hypothesis but suggest an independence of perceived size from perceived distance.     

Effects of Differential Instructions and Anxiety Level on Discrimination Learning

Seventy-seven nonconserver-conserver dyads and 53 nonconserver-nonconserver dyads were given a conservation of length task which encouraged conflicting judgments from the nonconserving dyad. Ss were boys and girls aged 4 through 8. Control tasks for social dominance/compliance were also administered. All sessions were videotaped. The nonconserver-nonconserver dyads did not tend to produce the correct answer by perspective coordination and showed little posttest gain. Nonconservers who had been paired with conservers showed posttest gain on length, mass, liquid, and number conservation problems. Being the winner of an interaction session was associated with opposing the partner's judgment and with producing justifications in conserver-nonconserver dyads, but only with social compliance in nonconserver-nonconserver dyads. Justifications in support of conservation judgments were invariably by logical principles but very rarely so in support of nonconservation judgments. The results are discussed in terms of the relative importance of cognitive conflict and transmission as crucial social experiences in cognitive development, and in terms of the possibility that nonconservers may lack the notion of objective correctness relative to conservers.     

On the relationship between personality and time estimation

The influence of basic dimensions of personality, such as extraversion, neuroticism, and psychoticism, on estimation of time still appears to be unclear. Therefore, in the present study the relationship between Eysenck's basic dimensions of personality and time estimation was investigated in 34 male Ss. After filling in the short version of a German adaptation of the Eysenck Personality Questionnaire-Revised, Ss were required to reproduce target durations ranging from 5 to 40 sec. As a measure of performance, reproduction ratio scores, representing directional errors, and absolute error scores were computed. Correlational analyses revealed no indication of a linear relationship between neuroticism and time estimation. However, there was a tendency for extraverts to overestimate time and to make less accurate time judgments relative to introverts. Furthermore, Ss with higher psychoticism scores were less prone to overestimation of time intervals and showed better accuracy of temporal reproductions than Ss with lower psychoticism scores.     

Knowledge despite falsehood

I examine the claim, made by some authors, that we sometimes acquire knowledge from falsehood. I focus on two representative cases in which a subject S infers a proposition q from a false proposition p. If S knows that q, I argue, S's false belief that p is not essential to S's cognition. S's knowledge is instead due to S's belief that p′, a proposition in the neighbourhood of p that S (dispositionally) believes (and knows). S thus knows despite her false belief. The widely accepted and plausible principle that inferential knowledge requires known premises is unscathed.     

Emphasis on Experimental Procedure,Sex of Subjects and the Biasing Effects of Experimental Hypotheses

For a set of 20 male graduate student Es, the experimental hypotheses held were significant partial determinants of the responses Ss produced for Es. This effect of Es' hypotheses was more marked among Es made more conscious of their experimental procedure when collecting data from female Ss. Male Ss were found to be less susceptible than female Ss to the biasing effects of Es' hypotheses. Unexpected was the finding that for a minority of Es (15%) the data they obtained from their Ss were significantly opposite to the data they expected to obtain.     

Absolute and Relative Decision Processes in Eyewitness Identification

A prominent and long-standing theory of eyewitness identification decision making distinguishes between absolute judgments, based on the lineup members' match to the witness's memory of the perpetrator, versus relative judgments, based on match values relative to other lineup members. This distinction was implemented in a computational model and simulations showed that the model predicts an accuracy advantage for absolute judgments over relative judgments under some conditions. The present experiment tested this prediction by evaluating the accuracy of witnesses instructed to use relative or absolute rules. Contrary to predictions, the overall analysis did not show an absolute advantage. Additional exploratory analyses showed a relative advantage when the suspect was surrounded by high-similarity foils. These results are consistent with a model that assumes that side-by-side comparisons of lineup members increase diagnostic accuracy by allowing witnesses to give greater weight to more diagnostic features and less weight to less diagnostic features.     

Conceptualising ‘Authority’

Abstract

This paper attempts a conceptualisation of authority intended to be useful across all areas where the concept is relevant. It begins by setting off authority against power, on the one hand, and respect, on the other, and then spells out S₁’s authority as consisting in S₂’s voluntary action performed in the belief that S₁ would approve of it. While this definition should hold for authority generally, a distinction is made between three different kinds of authority according to what grounds them: personal, acquired and bestowed authority. Authority thus defined is then used as an example to argue that there is a kind of property that is response-dependent (R-D), but, consisting in all and only a response, is ontologically different from both secondary qualities and value judgments. While secondary qualities are interactive in that they depend on both the object and the perceiver and on what they are like, genuinely R-D qualities depend ontologically and metaphysically only on the responder. And while value judgments require a concept, R-D qualities require an action as a response. It is hoped that this metaphysical underpinning might be helpful in the discussion of authority in other areas of philosophy and beyond.     

Development of Body Build Stereotypes,Peer Ratings,and Self-Esteem in Australian Children

The relationships between self-esteem and peer group judgments to stereotypes attached to fat, average, and thin body builds were investigated in a study of 84 Australian boys and girls in grades 2, 4, and 6. 5 s performed three tasks: (a) rated drawings of fat, average, and thin children of their own age and sex on a 56-item checklist; (b) completed the Coopersmith Self-Esteem Inventory; and (c) named classmates who fitted 12 of the items of task a. Results indicated that all age groups held firm body build stereotypes: negative for fat figures, positive for average figures. The strength of the stereotypes increased with age. However, S s did not apply these stereotypic judgments to their classmates, nor were Ss’ self-esteem scores related to their own body build or popularity. Thus, the use of stereotypes in relation to the social inculcation hypothesis must be seriously questioned, as there was no evidence that Ss related their idealized body build norms to themselves or to peers.     

Repeated Auditory Stimulation of the Startle Response in the Guinea Pig

Simulated and behavioral personal space measures and the Sensation Seeking Scale were administered to 20 males and 20 females. In the simulated measures Ss positioned male and female top profiles relative to a top profile representing themselves at each of nine equally spaced angles. For the behavioral measure Ss were approached by a male or female at each of the nine angles.

The female “swinger” had greater simulated personal space. Males who liked new and interesting experiences had greater side and diagonal simulated personal space, and females high on the same scale had a closer behavioral personal space toward males except at the sides. Males and females responded similarly to males and females approaching from various directions. However, there was no relation between front and side simulated personal space for males. Size of personal space relative to females tended to be highly correlated with size of personal space toward males. However, for male Ss there was little relation between front personal space toward males and females. For male Ss simulated personal space and behavioral personal space were highly correlated. For female Ss the two measures were almost completely unrelated.     

Ocular Movements in Reversibility of Perspective

To explore the role of acoustic factors in visual detection, this study employed 40 deaf and hearing Ss. Ss were requested to cancel all the letters “e” in a passage from Treasure Island. Results were analyzed in terms of probabilities of missing a pronounced or silent e and the e in the word “the.” Hearing and hard of hearing Ss were more likely to miss silent e's than pronounced e's. There was no significant difference between silent and pronounced e's for the profoundly deaf. Deaf and hearing Ss missed significantly more e's in “the” than pronounced or silent e's. The deaf, when compared to the hearing Ss, were more efficient in detecting pronounced and silent e's. They did not differ significantly from the hearing Ss in detecting the e in “the.”     

Through the looking glass: how the relationship between an object and its reflection affects the perception of distance and size

This is the first study to test the extent to which reflections help locate objects in space and perceive their size. For planar mirrors, the relative size of a target and its reflection is informative about the absolute distance of the target in units of the distance between target and mirror surface. When the target is near the mirror, target and reflection are similar in size; as the target moves away from the mirror, the difference in size increases. Observers saw a pair of objects in front of a mirror and judged relative size and distance (separately). Other visual cues to size and distance were eliminated, except lateral offset, which was tested in experiment 3. Experiment 2 controlled for the presence of directional feedback. Results showed orderly psychophysical functions for both size and distance with steeper slopes for distance judgments. In experiments 4 and 5 stereograms were used. Even when binocular information was present, the additional cue provided by reflections increased the accuracy of size and distance judgments. The same pattern of results was observed in the absence of feedback.     

Biased decision‐making: developing an understanding of how positive and negative relationships may skew judgments

The current experiment examines if and when children consider the possibility of relationships skewing judgments when evaluating judgments in different contexts. Eighty‐seven 6‐year‐olds, 8‐year‐olds, 10‐year‐olds, and adults heard stories about judges who made decisions matching or mismatching possible relationship biases (e.g. a judge choosing a friend or an enemy as the winner) in contests with objective or subjective criteria. While even 6‐year‐olds distinguished between subjective and objective contests, neither children nor adults focused on the objectivity of the contest criteria when evaluating a judge's claims. Instead, by age 8, if not earlier, children focused on relationships, trusting judgments that mismatched someone's relationship biases and discounting judgments that matched someone's relationship biases. The findings also suggested that children are better at recognizing that a judgment may have been biased than predicting that one will be, and that they may understand that negative relationships may skew judgments before positive ones.     

Can I Reach That Sticker? Preschoolers' Practical Judgments About Their Own and Others’ Body Size

Research to date has focused mostly on children's representation of their physical self as a prelude to the development of a theory of mind (ToM) and on their understanding of the self as distinct from others over time. Whether children approaching the well-known age of ToM mastery are also accurately appraising their own body's functional relationship to the everyday environment remains largely an unanswered question. Little work has investigated typical preschool-age children's explicit accuracy when making judgments about their own body's proportions. In the current study, 98 preschoolers made 16 practical judgments about whether their own body or an experimenter's body could fit through an apparatus (half of the apparatuses were 30% smaller than the body in question, and half were 30% larger). Overall, accuracy increased with age but was unrelated to body size. Children in all age groups performed above chance, and accuracy did not differ depending on target (e.g., self or other). Children in a comparison condition judging fit of inanimate objects (n = 23) performed similarly, though showed less evidence of “yes” bias, and there were no age-based differences in accuracy. Results are discussed with regard to preschoolers’ developing body awareness, as are implications for research protocols in which children are asked to accurately identify their own body size and shape from an array.     

Directional separation and the size cue to distance

Summary The effectiveness of the relative size cue to distance as a function of directional separation was investigated with the successive presentation of two luminous frames of the same shape but different visual angle. Either 0° or 180° of separation occurred between the successive presentations. In Exp. I the frames at 5 feet were viewed monocularly through a restrictive aperture. In Exp. II, the same frames were viewed monocularly through a lens such that the frames were at an accommodative distance of 100 feet. Reports of both the size and distance of the frames were obtained in each of the experiments. The results were analyzed in terms of the absolute size cue to distance occurring on the first presentations as well as the relative size cue to distance occurring between presentations. There was a tendency (not always statistically significant) to report the smaller frame at a farther distance than the larger frame, but only in Exp. II is there evidence that this tendency was greater on second than on first presentations. Therefore in Exp. II the relative size cue to distance was demonstrated to occur independently of the absolute size cue and it occurred at least as readily for the 180° as for the 0° separation between successive presentations. In both experiments the results from the size reports provide evidence for the presence of the relative size cue between successive presentations for both the 180° and 0° separations. It is concluded that the relative size cue is as effective when O must turn 180° to view the successive stimuli as when the successive stimuli are presented along the same line of sight. The procedure that is sometimes used of employing large directional separations in an attempt to avoid the relative size cue is, therefore, considered to be inappropriate. The results of the study were discussed in relation to a distinction between cognitive and perceptual processes in judgments of size and distance. Both the data of the present study and other results in the literature such as the size-distance paradox were analyzed in terms of a schema in which perceptual processes provided a basis for the rapid utilization of cognitive information.This investigation was supported by PHS Research Grant No. NS 08883, from the National Institute of Neurological Diseases and Strokes.
