The present study sought to determine whether significant relationships exist between life value preferences and personality traits and to describe the nature of any relationships identified. Administered to 310 undergraduate and graduate students were the 16 PF personality inventory and a 55-item Life Values Inventory which assessed values governing life styles and orientations. A factor analysis of the Life Values Inventory resulted in the identification of 14 life values dimensions. Factor scores for these 14 dimensions were then employed in a canonical analysis and a factor analysis with the 16 PF scores. The canonical analysis yielded results significant at the .001 level. The factor analysis yielded 10 factors, many of which displayed shared common-factor variance between Life Values and 16 PF variables. The interpretation of that shared variance identified several personality correlates of life values that suggested causal and developmental interactions of some value in describing and explaining human behavior.  相似文献

Twenty-four 5-week-old infants sucked significantly less when shown a schematic face in which the eye dots oscillated at 4 or 7 cm/sec than when shown the same face with the eye dots oscillating at 1 cm/sec. When identical moving dots were presented in the absence of the surrounding facial configuration, infants showed the same pattern of response. These results indicate (a) that 5-week-old infants can attend to intrastimulus movement, and (b) that the “externality effect” does not extend to compound visual displays which have moving internal elements.  相似文献

This study assessed the ability of Pascual-Leone's Theory of Constructive Operators to predict the minimum age or maturational level at which integration of a motor task could be achieved. Children 5–12 years of age (n=114) performed a discrete motor task requiring a constrained circular movement to be integrated with an unconstrained linear movement to a target. The Theory of Constructive Operators and the principles of constructive cognition were used to generate a model of task performance. Based on the model and in accordance with the theory, it was predicted that 5- to 6-year-old subjects would lack the cognitive capacity (M-capacity) to efficiently integrate this task. An analysis of covariance for age was performed on task parameters reflecting integration (and highest M-demand) with movement speed as the covariate. Scheffé contrasts supported the prediction as 5- to 6-year-old subjects were inferior to each of the other age groups (p < .05). Furthermore, no significant differences were found to exist between any of the older age groups.  相似文献

Subjects who came to an experiment expecting to receive a moderate amount of money for performing a task were then told, either before or after performing it, that their pay would be higher than, equal to, or less than they had expected. When the actual payment was announced after the task was performed, subjects' evaluations of the task increased with the amount they were paid; however, they estimated a higher rate of pay to be appropriate if they received either more or less than they expected than if they received what they expected. When the actual payment was announced before the task was performed (and before subjects made their decision to perform it), a different pattern emerged. Subjects rated the task more attractive when they were offered either more or less than the expected amount, while their judgments of the appropriateness of the pay offered increased with the amount of the offer. Implications of the results for incentive and dissonance theories as well as self-perception and equity theories are discussed.  相似文献

Subjects with initially extreme or moderate positions (based on a median split) recorded a consonant speech under public, private, or no commitment and later received a strong, mild, or no attack on their position. Extremes were more ego-involved in terms of wider latitudes of rejection, narrower latitudes of non-commitment, and greater resistance to attack, relative to moderates. Commitment had no effect for extremes, suggesting a ceiling effect on changes in the latitudes and resistance to attack for initially high levels of ego-involvement. For moderates, commitment resulted in narrower latitudes of noncommitment, wider latitudes of rejection (greater rejection of discrepant positions), and greater resistance to attack, suggesting that commitment may elevate ego-involvement with the issue. Commitment and ego-involvement may increase the salience of one's attitude position in later situations, thereby increasing the probability of attitudeconsistent behavior.  相似文献

We analyzed the relationship between age and clinical type of aphasia in 167 right-handed men who had suffered cerebrovascular accidents. Patients with unequivocal diagnoses as Broca's, Wernicke's, anomic, conduction, and global aphasics were considered. The median age of the Broca's group (51 years old) was significantly lower than that of the total group (55.8 years old), while the median age of the Wernicke's group was significantly higher (63 years old). Moreover the incidence of Wernicke's aphasia increased steadily with age, while incidence of the other types of aphasia peaked in the sixth decade and then diminished with increasing age.  相似文献

General intelligence may set structural feature limitations on three aspects of selective attention: direction, adjustability, and breadth. Amiable hypotheses considered are that subjects of varying intelligence may (1) have some partially fixed tendencies to look at different dimensions of stimuli, (2) have varying rates of adjusting their direction of attention, and (3) have varying upper limits on breadth of attention for tasks demanding it. Data, theory, and methods bearing on these hypotheses were reviewed from the domain of visual discrimination learning.  相似文献

To secure systematic information on spelling abilities following damage to the dominant hemisphere, a test probing performance in three modalities of response was administered to a group of aphasic patients. Except for a predictable deficit among anterior aphasics in oral spelling, anterior and posterior aphasics exhibited comparable performances on the measures of spelling. However, anterior and posterior aphasics differed from one another on the kinds of words they most accurately spelled, the errors they were prone to make, and certain strategies which they characteristically adopted. These results suggest two alternative approaches to spelling: one approach, common in posterior aphasics, entails choosing letter combinations on the basis of their customary sounds; a second approach, common among anterior aphasics, appears to rely on a partially preserved image of the word's appearance.  相似文献

The competency of language comprehension was evaluated in three groups: anterior aphasics, posterior aphasics, and normal control subjects. Test material was divided into two sentence groups (Fill in the Blank and True/False) emphasizing either (1) semantic, “real world,” identity words or (2) syntactic, relational words, and one paragraph interpretation task. Matching auditory and visual (written) presentations were given. The control subjects performed almost flawlessly but many errors were made by each aphasia group. Qualitative study revealed a marked difference in the comprehension problem of the two groups. The anterior aphasic group performed well on semantically weighted sentences but made errors on syntactically weighted material, regardless of mode of presentation. In contrast, the posterior aphasics made almost the same number of errors on both types of material, regardless of mode of presentation. These findings support the concept of defective language comprehension in anterior aphasia and further suggest that the defect centers on the syntactical structures which are also poorly handled in expressive output.  相似文献

Infarct si?e (number of 1-mm2 pixels in the lesion) on CT scans of 30 aphasia patients was obtained with a semiautomated computer program. The mean number of lesion pixels present per slice containing lesion was approximately 500 for mild aphasias (transcortical motor and conduction), 700 for Wernicke's, 1000 for Broca's, 1500 for mixed, and 2000 for globals. These differences were significant for 1115 of the group pairwise comparisons. When lesion locus was controlled for in the anterior/posterior plane, 73–100% of the aphasia patients were correctly classified as to type of aphasia by a discriminant analysis utilizing only the number of lesion pixels present on two CT slices. Different slice combinations were used for different aphasia group comparisons. There was a significant correlation between severity of aphasia and lesion size. There was a significant correlation between lesion size and the CT numbers in the lesion. This type of analysis may be useful to predict the prognosis for recovery potential in aphasics who have CT scans performed at 2 months poststroke.  相似文献
