THE EFFECTS OF PARTICIPATION AND GOAL DIFFICULTY ON PERFORMANCE

Previous research comparing the effects of assigned versus participatively set goals on performance were essentially tests of the null hypothesis in that goal difficulty level was not systematically manipulated. The present laboratory study investigated the effects of assigned versus participatively set goals, and the effects of varying goal difficulty level on an arithmetic task. Eighty-six college students were assigned to either a participative goal condition or one of three assigned goal conditions. In two of the assigned goal conditions participants were assigned goals equal to those set in the participative condition, the difference being that individuals in one group were assigned goals at random and those in the other group were assigned goals on the basis of their premeasure scores. Participants in the third assigned goal condition were randomly assigned a goal in the top quartile of the goals set participatively. As hypothesized, individuals with hard assigned goals had higher performance than peers with lower goals set in a participative manner. Contrary to modern organizational theory, individuals with participatively set goals did not have higher performance than those with assigned goals of equal difficulty. Personality traits were not found to moderate the effects of goal setting on performance.     

EFFECTS OF PROBLEM DIFFICULTY AND REINFORCER QUALITY ON TIME ALLOCATED TO CONCURRENT ARITHMETIC PROBLEMS

Students with learning difficulties participated in two studies that analyzed the effects of problem difficulty and reinforcer quality upon time allocated to two sets of arithmetic problems reinforced according to a concurrent variable-interval 30-s variable-interval 120-s schedule. In Study 1, high- and low-difficulty arithmetic problems were systematically combined with rich and lean concurrent schedules (nickels used as reinforcers) across conditions using a single-subject design. The pairing of the high-difficulty problems with the richer schedule failed to offset time allocated to that alternative. Study 2 investigated the interactive effects of problem difficulty and reinforcer quality (nickels vs. program money) upon time allocation to arithmetic problems maintained by the concurrent schedules of reinforcement. Unlike problem difficulty, the pairing of the lesser quality reinforcer (program money) with the richer schedule reduced the time allocated to that alternative. The magnitude of this effect was greatest when combined with the low-difficulty problems. These studies have important implications for a matching law analysis of asymmetrical reinforcement variables that influence time allocation.

DIMENSION ANALYSIS OF THE PERCEPTION OF MUSICAL STYLE

W edin , L. Dimension analysis of the perception of musical style. Scand. J. Psychol ., 1969, 10, 9 7–108.-The subjective similarity of ten short excerpts from musical works ranging over the period of 1720–1890 was studied by (I) the direct multidimensional ratio scaling method and (2) by the method of similarity analysis. Factor analysis extracted three or four factors depending on the degree of musical training of the subjects. The differentiation and inter-pretability of the factors were higher for subjects with more musical training and interest. The factors were labeled 'Baroque', 'Rococo', 'Viennese classicism' and 'Romanticism'.     

UNWANTED INTERCOURSE: THE DIFFICULTY OF SAYING NO

Unwanted intercourse occurs when a reluctant partner is induced to acquiesce against her (his) will by psychological pressure from the would-be lover, but without the use of or the threat of force. An earlier study found that 30% of a representative probability sample of senior women in a liberal arts college had experienced unwanted intercourse. College women's ( N = 76 ) perceptions of the unwanted intercourse situation were assessed by projective and by questionnaire methods, using a videotaped stimulus cue. Results indicate that highly negative feelings are attributed to the man in the refuse situation, and to the majority of the women in both the accept and refuse situations. A hedonic calculus analysis based on the ratio of negative to positive feelings in the stories demonstrates the cost-benefit superiority of accepting unwanted intercourse in spite of the fact that the women's feelings are predominantly negative. A theory of unwanted intercourse is proposed that attributes the high rate of unwanted intercourse to four societal norms: (a) current remnants of the ideology of male supremacy, (b) the norm of male initiative, (c) the lack of positive sexual experience norms for women, and (d) the stroking norm for women.     

THE RELATIONSHIP BETWEEN DIFFICULTY AND FACTOR LOADINGS OF SOME VISUAL-PERCEPTUAL TESTS

WERDELIN, I. & STJERNBERG, G. The relationship between difficulty and factor loadings of some visual-perceptual tests. Scand. J. Psychol. , 1971, 12, 21–28. – The study aimed at investigating whether it is possible to change factor loadings by varying the difficulty and complexity of the same visual-perceptual tests. 171 sixth grade pupils were given 27 tests. Some of these defined reference factors, others were differently difficult versions of four tests from separate parts of the visual-perceptual field. Data were treated by factor analysis, yielding the four factors R, S, N and P. It was found that the more difficult the test the higher its loadings on the S and R factors, and the easier the test the higher its loadings on the N and particularly the P factor.     

MUSIC OF THE SIKH DIASPORA: DEVOTIONAL SOUNDS,MUSICAL MEMORY AND CULTURAL IDENTITY

This paper explores the role of devotional music in the construction of Sikh identity in diasporic contexts. In particular, it examines a heterodox Sikh community in the UK and an orthodox Sikh community in Hong Kong from a comparative perspective, showing how music helps to clarify continuities and discontinuities in Sikhism worldwide. I provide ethnographic accounts of musical performances in different locales within gurdwara-s. Following a summary of current conventions in Sikh music performance and pedagogy, two ethnographic accounts are provided. The first is a musical ethnography of the Namdhari Gurdwara in Leicester where Hindustani classical music is performed alongside traditional ritual genres. The second site is a similar ethnographic study of the Khalsa Diwan Gurdwara in Hong Kong where the issues of diasporic identity and musical memory are foregrounded.     

ON THE PROBLEMS OF PERCEIVED DIFFICULTY

BORG, G., BRATFISCH, O. & DORNI'C, S. On the problems of perceived difficulty. Scand. J. Psychol. , 1971, 12, 249–260.–The development and meaning of the concept of "perceived difficulty" is presented. A concise survey of experiments carried out so far is given with regard to the main theoretical, methodological and applied problems at which the investigations aimed. A substantial part of the paper is devoted to the analysis of the concept of perceived difficulty and to the possibilities of measurement. The concept of perceived difficulty is dealt with also in a differential connection and a model for interindividual comparisons is suggested. It is emphasized that a systematic investigation of perceived difficulty is both possible and useful, and that it yields an opportunity to improve and facilitate the construction of psychological tests. Finally, possible future research projects are briefly outlined.     

NEWTON AND KANT: QUANTITY OF MATTER IN THE METAPHYSICAL FOUNDATIONS OF NATURAL SCIENCE

Immanuel Kant's Metaphysical Foundations of Natural Science (1786) provides metaphysical foundations for the application of mathematics to empirically given nature. The application that Kant primarily has in mind is that achieved in Isaac Newton's Principia (1687). Thus, Kant's first chapter, the Phoronomy, concerns the mathematization of speed or velocity, and his fourth chapter, the Phenomenology, concerns the empirical application of the Newtonian notions of true or absolute space, time, and motion. This paper concentrates on Kant's second and third chapters—the Dynamics and the Mechanics, respectively—and argues that they are best read as providing a transcendental explanation of the conditions for the possibility of applying the (mathematical) concept of quantity of matter to experience. Kant again has in mind the empirical measures of this quantity that Newton fashions in the Principia, and he aims to make clear, in particular, how Newton achieves a universal measure for all bodies whatsoever by projecting the static quantity of terrestrial weight into the heavens by means of the theory of universal gravitation. Kant is not attempting to prove a priori what Newton has established empirically but, rather, to clarify the character of Newton's mathematization by building Newton's empirical measures into the very concept of matter that is articulated in the Metaphysical Foundations.     

年龄、作业难度和训练对成人记忆的影响

采用“联想学习”、“图象自由回忆”和“附加联想”三项目,对９０例成人（分为青年、老年和老老年组各３０例）进行记忆测查和训练,目的为探讨年龄,作业难度和训练对记忆的影响。结果表明：青年组记忆成绩明显高于老年和老老年组,后两组无显著差异;无关联想的年龄差异大于有关联想,作业难度扩大了年龄差异;各年龄组训练后记忆得到明显改善,并且训练扩大了年龄和作业易难的差异。由此可见,记忆受年龄、作业难度和训练三因素的相互作用,也再次证实了老年认知功能具有一定的可塑性。     

POWER AND THE QUALITY OF SAME-SEX FRIENDSHIPS

Does the quality of same-sex friendship depend on the gender of the friends and the balance of power between friends? Fifty-four men and 60 women undergraduates evaluated two of their same-sex friendships, one equal in power and one unequal in power. The quality of each friendship was rated in terms of emotional closeness, satisfaction, liking, self-disclosure, and rewards. In general, most young adults evaluated their friendships positively. Mixed-model multivariate analyses of variance (MANOVAs) found significant main effects of gender and power on ratings of quality, but no interactions. Consistent with previous research, women generally evaluated their same-sex friendships more positively than did men. Gender differences were relatively small in magnitude and were not found for all indices of relationship quality, however. As predicted, participants rated equal-power friendships significantly higher than unequal-power friendships on all measures of quality. Power appears to be an important but largely neglected element of friendship.     

THE ECOLOGY OF SPELLING: A LENS MODEL ANALYSIS OF SPELLING ERRORS AND STUDENT JUDGMENTS OF SPELLING DIFFICULTY

Abstract

Students who were identified by their teachers as poor spellers were asked to judge the difficulty they would have in spelling each of 100 words that were representative of the sorts of words they tended to misspell in their various subject areas (the spelling ecology). After making difficulty judgments, the students were then asked to spell each word on the list. Spelling errors were scored as either phonetic or nonphonetic. The researchers rated each of the 100 words on ten characteristics: number of letters, syllables, letters per syllable, double and silent letters; schwa, ambiguous, and unusual sounds; and two measures of familiarity to the student. This task was replicated after a four‐week period to check for spelling and judgment consistency. Spelling errors and judgments of spelling difficulty were analyzed using the double system Lens Model using the ten word characteristics as “cues” in the analysis. Results showed only moderate agreement between difficulty judgments and spelling errors, and fairly consistent differences between those word characteristics that were predictive of perceived spelling difficulty and those predictive of phonetic and nonphonetic errors. Several different patterns of cue weights were noted for spelling errors whereas spelling difficulty judgments were primarily based upon word familiarity. Implications are drawn for the further investigation of spelling errors and of how students decide what constitutes a “hard” word to spell and for the potential improvement of the spelling judgment process using cognitive feedback from the Lens Model.

The characterization of spelling as a cognitive activity has received increasing attention in the educational research literature. For example, two recent issues of Reading Psychology (Numbers 2 and 3, 1989) were entirely devoted to research on spelling. Much of this work has focused on spelling strategies (e.g., Anderson, 1985, Kreiner & Gough, 1990, and Olson, Logan, & Lindsey, 1989), spelling problems and types of errors (e.g., see Frith, 1980, and Weber & Henderson, 1989), and the relationship between spelling and reading (e.g., Templeton, 1989, and Zutell & Rasinski, 1989). However, there has been very little research on the issues of the criteria individuals use in deciding that a particular word is difficult or easy to spell, and the accuracy and effects of such a decision. We refer here to the more metacognitive aspects of the task ecology of spelling, and the effects of which may be shown in decisions to avoid or at least minimize the cognitive efforts expended in spelling a perceived “hard” word.

The issue of judging spelling difficulty forms the focus of the present study. Here we attempt to document those features of a word that make students think it would be hard or easy to spell. We then relate this judgment process to errors made when students attempt to spell words. Finally, we compare the relative importance of various features of words as predictors of both difficulty judgments and actual spelling errors.     

A COMPARISON BETWEEN THE SEMANTIC DIFFERENTIAL AND SIMILARITY ANALYSIS IN THE MEASUREMENT OF MUSICAL EXPERIENCE

N ordenstreng , K. A comparison between the semantic differential and similarity analysis in the measurement of musical experience. Scand. J. Psychol ., 1968, 9,89–96.—Ten pieces of music were rated by a group of broadcasting sound-controllers using two different scaling techniques, the semantic differential ratings of each sound on 32 scales, and similarity ratings for all pairs of sounds. The two scaling techniques were compared matching factor spaces by transformation analysis. The results indicate almost perfect similarity of the factor structures, which suggests that similarity analysis and the semantic differential in fact measure the same thing.     

任务难度对于返回抑制出现时间的影响

在返回抑制的范式下,以大学生为被斌,采用线索一靶子模式进行了两项实验.实施一发现,在觉察任务中,返回抑制在线索和靶子的时间间隔(SOA)为300ms时出现;在辨别任务中,返回抑制在SOA为700ms时出现.实验二发现在选择任务中,返回抑制在SOA为1300ms时出现.这些结果表明,随着实验任务的难度逐渐增大,返回抑制出现越来越晚.实验任务的难度是影响返回抑制出现时间的一个重要因素.     

MEASURING SOCIAL-COMMUNICATIVE ANXIETY: SOCIAL DESIRABILITY AND THE FAKABILITY OF SCALE RESPONSES

Three studies are reported that examine the social desirability and fakability (transparency) of a number of self-report measures of social-communicative anxiety. Results indicate that social desirability, assessed as a personality dimension, is generally unrelated to measures of social and communicative anxiety. However, virtually all measures of the anxiety were transparently fakable. When asked to portray themselves positively, subjects consistently responded as low-anxious; when asked to look undesirable, subjects completed the measures to suggest high anxiety.

WORD FREQUENCY AND WORD DIFFICULTY:

Abstract— This article compares word counts made using four different collections of text, including one based on collections of electronic text For each of the collections, standard word frequency indices were computed and compared with a carefully developed list of words ranked in order of difficulty as determined by vocabulary tests Correlations between the word frequency indices and word difficulty ranks show that word frequencies for all four corpora are highly correlated with word difficulty Despite these high correlations, the results show also that the difficulty of some words is not estimated accurately by word frequency The reasons for disparities between word frequency and word difficulty are not clear The high correlations obtained for the corpus based on electronic text suggest that this method of text sampling has potential but that caution is advisable in conducting such collections.
