Cognitive and motivational determinants of academic achievement and behaviour in third and fourth grade disadvantaged children.

While most studies on the determinants of learning deal with either cognition or motivation, there is a growing awareness that both should be considered. Our purpose was to examine the relative roles of cognitive and motivational factors for the scholastic achievement and behaviour of disadvantaged children. Cognition was conceptualised in terms of the psychosemantic theory that assesses cognitive processes by characteristics of the individual's meaning assignment (Kreitler & Kreitler, 1987a). Motivation was conceptualised in terms of the cognitive orientation (CO) theory which assumes that cognitive contents guide behaviour (Kreitler & Kreitler, 1982). Participants were 57 third and fourth graders of both genders, recommended for a remedial summer programme. They were administered the Meaning Test assessing cognitive abilities; the CO Questionnaire of Motivation for Learning assessing the disposition to learn; and the Metropolitan Achievement Test and the IOWA tests assessing verbal, mathematical and working skills. Teachers completed the Teacher-Child Rating Scale assessing six scholastic behaviours. Regression analyses showed that all dependent variables were predicted by the cognitive and motivational variables, better by specific than global predictors. Cognitive variables contributed more to the predictions, especially of academic achievements, and more in the case of verbal than mathematical abilities. In girls, motivational factors played a larger role than cognitive factors, absolutely and relative to boys. Implications for promoting scholastic achievements are discussed.

Life satisfaction and health in cancer patients, orthopedic patients and healthy individuals.

Life satisfaction (LS) is one of a set of constructs defining quality of life. Previous studies showed that LS was sometimes related to health and sometimes not. The study was designed to examine the relation of LS as a general construct to satisfaction in specific domains. We assumed that there is a tendency to maintain an acceptable level of LS even under stressful and threatening conditions, that it is related to optimism and that the likelihood of attaining satisfaction in a particular domain affected the selection of domains on which LS is based. We expected that in cancer patients LS would be related to more domains but not to health. The study was done with 55 head-and-neck cancer patients, of all stages and grades of tumor; 51 orthopedic patients, victims of accidents with good recovery chances; and 55 healthy individuals. The healthy individuals and orthopedic patients were matched (in terms of group values) to the cancer patients in age, gender and education. Single-item measures of LS and optimism, and a questionnaire with 49 multiple-choice items assessing adjustment in 13 domains were administered to all subjects. The results showed that in cancer patients LS was related to most domains but not to health and not to optimism, whereas in the other groups it was related to few domains including health, and also to optimism. The findings support the tendency to maintain LS with the materials available to the individual, and show that health is related to LS only if its maintenance or attainment are realistic goals. Thus, both bottom-up and top-down theories of LS are supported.

Cognitive orientation and genital infections in young women.

The purpose was to explore the psychological determinants of common genital infections in young women. The study was done in the framework of the cognitive orientation theory which assumes that cognition guides behavior and provides predictions of behaviors and psychophysiological phenomena. We expected that beliefs of four types (about self, norms, goals, and general) would predict the occurrence and/or frequency of 17 gynecological symptoms (e.g., itching, swelling, different vaginal discharges, abscesses). The subjects were 195 female volunteers, undergraduates, about 23 years old, without gross gynecological disorders, mostly (87.7%) unmarried, mostly (83.6%) having had intercourse. They were administered anonymously questionnaires about demographic variables, frequency and treatment of gynecological symptoms and 3 urological ones (for control), and about cognitive orientation that referred to pretested themes (e.g., assertiveness, hypochondriasis). Stepwise discriminant and regression analyses showed that the belief types enabled predicting the occurrence and frequency of all symptoms, with a mean 34.5% improvement over the 50% chance level, accounting for 45.7-67.2% of the variance. Also the urological symptoms were predicted although at a lower level. Discussion focuses on the specificity of cognitive-motivational determinants and their role in producing conditions favoring physical pathology.

The psychological profile of women attending breast-screening tests.

Though the benefits of early detection of breast cancer are generally known, only few women attend breast-screening examinations. The study was designed to gain insight into the problem by exploring the psychological profile of clinic attenders. In order to find out whether there is such a profile, 210 self-referred women were compared with 210 nonattending women, from the same working and social environments, matched in age, education and occupational level. All subjects were administered 10 tests in 7 domains. The tests were administered as part of a health survey. The results showed that clinic attenders scored higher on negative emotions and total emotions and lower on positive emotions; higher on repression; lower on daydreams; lower on range of self-concept, references to others and negative self-references but higher on positive self-references; scored higher on self-references describing oneself in a functional and in a passive way and scored lower on those describing oneself in terms of one's attitudes, body and appearance; scored lower on neuroticism; scored lower on different somatic complaints and health orientation but higher in alexithymia. No differences were found in authoritarianism, locus of control and self-complexity. Conclusions are that there is a psychological profile of clinic attenders, that it is focused on dysphoric emotions, psychological disease promotion and defensiveness and that it includes characteristics of the construct that is sometimes called the cancer-prone personality.

Cognitive antecedents of imitativeness and persistence in children with mental retardation.

Two studies with children with mild mental retardation were conducted within the framework of the cognitive orientation theory, which describes how cognitive contents and processes guide behavior and thus enable behavior predictions and modifications. The studies were designed to test whether specific clusters of beliefs would predict imitation and persistence among individuals with mental retardation. Behavioral measures and questionnaires that assessed beliefs were administered. The belief scores were related significantly to the behaviors. Implications concerning motivation, the developmental-difference controversy, and individual differences were discussed.

Rigidity in mentally retarded and nonretarded children.

The dependence of rigidity on task difficulty was examined. The hypothesis was that mentally retarded subjects would be more rigid than would nonretarded subjects on difficult but not on easy tasks. An intelligence test and seven rigidity tests varying in difficulty were administered to 45 retarded and 45 MA-matched nonretarded subjects. Factor analyses yielded one rigidity factor for the retarded group and two for the nonretarded group. In both groups the rigidity tests were interrelated and formed a Guttman simplex structure in terms of difficulty. The groups did not differ on three easy tests but did differ on four more difficult tests. The results were interpreted mainly in a motivational framework, with implications concerning mental retardation and rigidity as an interactional concept.

Probability learning and Piagetian probability conceptions in children 5 to 12 years old.

This study focused on the relations between performance on a three-choice probability-learning task and conceptions of probability as outlined by Piaget concerning mixture, normal distribution, random selection, odds estimation, and permutations. The probability-learning task and four Piagetian tasks were administered randomly to 100 male and 100 female, middle SES, average IQ children in three age groups (5 to 6, 8 to 9, and 11 to 12 years old) from different schools. Half the children were from Middle Eastern backgrounds, and half were from European or American backgrounds. As predicted, developmental level of probability thinking was related to performance on the probability-learning task. The more advanced the child's probability thinking, the higher his or her level of maximization and hypothesis formulation and testing and the lower his or her level of systematically patterned responses. The results suggest that the probability-learning and Piagetian tasks assess similar cognitive skills and that performance on the probability-learning task reflects a variety of probability concepts.

Body image: the dimension of size.

In view of a dearth of clear data concerning phenomenal body size and the shortcomings of the assessment methods, the purpose of the present study was to apply a new kinaesthetically based Body Size Estimation method for investigating differences in size estimations of 10 body parts by men and women of different age groups, comparing them to estimations of a neutral object, and examining their interrelations and relations to attitudinal and personality variables. Two hundred and forty Israeli subjects, 80 (40 male, 40 female) in each of three age groups (4 to 6, 10 to 12, and 28 to 30 years) were administered estimations of body and object, figure drawing, and questionnaires in two individual sessions. Results showed overestimation of body size in all groups, decreasing regularly with age or U-shaped, few gender differences, differences from object estimations, a grouping into bodily and facial images, increasing unitariness, negative correlations with body cathexis and satisfaction, bodily sophistication, and the richness of the self concept and positive correlations with exercise, field dependence, and figure drawing distortions.

The cognitive orientation of expressive communicability in schizophrenics and normals.

The study dealt with expressive communicability (EC), i.e., the amount, fluency, elaboration, clarity, and veracity of the voluntarily transmitted information about oneself. Low EC is considered as a schizophrenic symptom and as a cause of interpersonal difficulties in normals. For investigating the motivational antecedents of EC we applied the cognitive orientation (CO) theory that deals with explaining, predicting, and manipulating behaviors by means of cognitive contents and processes. The hypotheses were that schizophrenics would have fewer positive and more negative EC manifestations than normals, and that beliefs of four types would predict EC in both groups. Subjects were 30 hospitalized schizophrenics and 30 matched normals of both genders. They were administered individually the CO questionnaire and role-playing situations providing EC scores. Hospital personnel and close acquaintances answered a 13-item questionnaire about the subjects' EC. The findings confirmed the hypotheses: schizophrenics differed from normals on all EC measures, and the beliefs predicted 81%-100% EC measures in each group and the whole sample. The discussion focused on theoretical implications for cognitive motivation, the similarity of the motivational processes in schizophrenics and normals, and therapeutic implications for changing EC by changing the relevant beliefs.

Curiosity and demographic factors as determinants of children's probability-learning strategies.

Children's curiosity, gender, activity level, and socioeconomic status (SES) were related to their performance on a partially reinforced discrimination-learning task. The 38 boys and 37 girls were in the first grade and were all white. Three factors of curiosity (manipulatory, conceptual, and about the complex) were assessed. Performance on the learning task was scored for the number of correct responses (maximizing) and for the frequency of three-step sequences reflecting variability, systematic patterning, and perseveration. In general, the three curiosity factors related negatively to maximizing and perseveration and positively to variability. (The same effects were found for activity level.) Systematic patterning related positively to one curiosity type and negatively to another. Girls used less maximizing and more systematic patterning than boys. The response choices of girls were affected more by differences in conceptual curiosity and those of boys by differences in curiosity about the complex. Activity level was unrelated to gender but differed with SES. The findings demonstrate the role of different curiosity factors in shaping response sequences and suggest some reasons for children's choice of probability-learning strategies.
