Development of organization in recall: A stages-of-learning analysis

An experiment is reported in which the effects of taxonomic organization on 7-year-old and 11-year-old children's free and cued recall of two- and four-category lists were examined. The data were analyzed using a stages-of-learning model that simultaneously delivers estimates of the impact of these manipulations on storage and retrieval components of recall. The results indicated that for the Grade 2 children providing a category label at the time of recall primarily enhanced storage whereas increasing the number of categories primarily enhanced retrieval. For Grade 6 children, on the other hand, the use of category labels to cue recall primarily enhanced retrieval, whereas increasing the number of categories affected both storage and retrieval in free recall, but only retrieval in cued recall. In addition, while older children were superior to younger children at both storing and retrieving information, age differences at retrieval were generally larger than those at storage.     

A cross-sequential analysis of developmental differences in speed of visual information processing

Development of processing speed was examined in three backward masking studies. The first verified the central nature of backward masking for children aged 8 and 11 years and for adults. The second suggested that task requirements were equivalent for children similar to those in Study 1, and that age differences in performance were not attributable to nonprocessing variables. The main cross-sequential study estimated speed of processing in 80 children (approximately 6 years to 13 years) and young adults using an inspection time task. Target exposure duration was varied to establish the time required to achieve a high level of discriminative accuracy. Estimates of processing speed increased until about 11-13 years of age; beyond this, the trend was less obvious, and it is possible that inspection time asymptotes at around the onset of adolescence. Performance improvement after 1 year could not be explained as resulting from practice since improvement among controls over a period of 2 weeks was significantly less. Correlations between estimates of inspection time made up to 2 years apart found the measure to be reliable.     

Delayed recognition memory for orientation by human infants

The familiarization/novelty preference paradigm was employed to study the effect of a delay (between the end of the familiarization phase and the beginning of the test phase) on discrimination of the orientation of square-wave gratings by 2- and 3-month-old human infants. Three stimulus pairs were studied: horizontal-vertical, non-mirror-image obliques, and mirror-image obliques. The data indicate that the members of the oblique-oblique stimulus pairs are confused in memory to a greater extent than the members of the horizontal-vertical stimulus pair. These findings are consistent with P.C. Bomba's (1984, Journal of Experimental Child Psychology, 37, 609-636) recent report that infants respond to the orientation of a visual stimulus in a categorical-like manner.     

Imagery, encoding specificity, and prose recall in 6-year-old children

Partial pictures depict only selected portions of prose passages. Partial pictures hypothetically aid retention by inducing young children to generate imagery for nonpictured prose. Results from two hundred eighty-eight 6-year-old children indicated that (a) partial pictures at study facilitate recall, (b) identical study and retrieval prompts facilitate recall, and (c) imagery instructions and training do not affect retention. Partial pictures apparently help children to encode information more efficiently at study, but there is no evidence that young children generate images with the aid of the partial picture cues, nor that they have a retrieval deficit for these images as suggested by M. Ruch and J. Levin.     

Three-state models of memory development: A review of advances in statistical methodology

A certain family of three-state Markov processes has been widely used in experiments on children's memory. Although the statistical machinery for these models is well developed in most respects, two shortcomings have been noted in recent literature reviews. First, the parameters of the models are not identifiable. Second, goodness-of-fit tests are laborious to execute and their sampling distributions are unknown. New procedures for dealing with these difficulties are reported.     

Control of children's observing responses by information feedback during visual discrimination learning

Four experiments examined the control of observing responses by information feedback during visual discrimination learning. Second-grade children participated in Experiment 1; kindergarten, second-, and fifth-grade children were subjects in Experiments 2 and 3, and grade 5 and adult subjects were tested in Experiment 4. In order to view the stimuli, subjects in Experiments 1, 2, and 3 activated lights in viewing boxes; in Experiment 4, stimulus fixations were measured using a corneal reflection technique. Fifth graders and adults observed the discriminative stimuli for longer times on trials following negative feedback than on trials following positive feedback; in contrast, kindergartener's observing was not affected by type of feedback. Second graders showed smaller and less reliable reactions to type of feedback than did older subjects. These results support the view that visual observing is controlled by cognitive processes associated with hypothesis testing.     

Children's affective,behavioral, and cognitive responses to social comparison

Relative outcomes in social commerce with peers are potent determinants of cognitions and behavior in young children. Although there has been considerable attention given to the behavioral consequences of social comparisons following the receipt of rewards, there has been less concern with cognitive or affective consequences. Additionally, little is known about the accrued effects of multiple social comparison experiences that may be consistent or inconsistent with one another. In the present study, young children received a constant level of reward but the amount they saw a peer receive was varied. There were two sequences of reward distribution, and in a given sequence children received either the same number of rewards as the peer (=), more (+), or fewer (?). In a 3 × 3 factorial design all possible combinations occurred. A negative inequality in reward distribution, no matter where it fell in a sequence, made children sad and inclined children to distribute fewer rewards to peers. When a sequence contained an initial experience of positive inequality, children decreased subsequent levels of self-reward. Experiencing a comparison that revealed a negative inequality in reward distribution also disrupted children's accuracy in appraising the overall distribution of rewards: even when an initial negative inequality was completely offset by an equivalent experience of positive inequality, children inaccurately concluded that they had received fewer rewards than their peers.     

The Depressive Experiences Questionnaire: revision and validation

The present study presents a new, unit-weight scoring system for the Depressive Experiences Questionnaire (DEQ). One hundred thirty-one college students completed the DEQ, the Bem Sex-Role Inventory (BSRI), and the Beck Depression Inventory (BDI). The revised DEQ scales were shown to have substantial levels of internal consistency. The three subscales of the revised DEQ were significantly correlated with the BSRI masculinity and femininity scales but not with gender. Significant correlations were also obtained between DEQ anaclitic, DEQ introjective scales and the BDI.     

Prejudice and neurotic symptomatology among white South Africans

Van der Spuy and Shamley (1978) have assembled evidence suggesting chronically elevated levels of neurotic symptomatology among both white and black South Africans. They have argued that these elevated levels could be attributed to the experience of racial discrimination and prejudice. New data obtained from a reasonably representative national sample of white South Africans (N = 782) did reveal symptom scores substantially and significantly higher than scores previously reported for a large community sample in the United States. On the other hand, partial correlational analyses did not indicate any consistent pattern of association between antiblack prejudice and symptom scores among white South Africans. Therefore, intergroup conflict in a sharply stratified society may affect symptomatic levels in individuals by influencing the general quality of social life.     

Spiritual support for caregivers of dementia patients

Dementia is considered the major psychiatric disorder of old age and affects over 4 million people in the United States. As Alzheimer's disease and other dementias progress, the patient can become increasingly dependent on the family for care. This dependency can place the caregiver in a role that is both difficult and demanding. In this study coping strategies used by family caregivers of dementia patients and caregivers' sense of burden were assessed. Burden scores were significantly correlated with spiritual support, an external coping strategy. When spiritual well-being is integrated with medical and psychosocial needs, the clergy and spiritual community can play an integral role in the care for families and dementia patients.
