Heritability is defined as the proportion of a manifested trait's varience that is due to genetic variation. Sixty-five pairs of twins were employed to investigate the heritability of: (1) short term memory (Jensen's Level 1), operationalized using of modified "digit span" test; (2) the general intellective factor (Jensen's Level II),…

The relationship between the effects of morphological complexity and associative production frequency was investigated in two experiments on sentence verification. The purpose of the study was to investigate how morphologically derived words are represented in memory. (Author/RM)

Subjects who read about the legislative process in Oklahoma demonstrated slightly better factual recall of the material than subjects who saw a film version of the same material. (GW)

Effects of verbal and pictorial elaboration on long-term memory were assessed. Second-graders learned a list of nouns by the paired-associate method, and long-term retention was assessed after seven days. Results indicated that although elaboration facilitates initial acquisition, it neither helps nor hinders long-term retention. (Author/RD)

The accuracy of the feeling-of-knowing was assessed with regard to recall and recognition under three conditions: advanced or nonadvanced organizers; learned or nonlearned information; and sex differences. Twenty subjects learned pair-associates and were tested for recall and recognition, accompanied by ratings of feeling-of-knowing strength.…

A directed forgetting task was used in an investigation of the conditions under which normal and educable mentally retarded junior high school students would disregard irrelevant information. Results showed that irrelevant information in memory interfered with the performance of only the retarded group, when given a minimal explanation of the…

The probability of recognizing a member of a word pair tested with the pair intact was shown to equal the probability of recognizing a single word plus the probability of recalling an unrecognized word. (Author/NCR)

A correspondence exists between a simplified data collection method employing results from a post test for graphic skills in kinematics, and a rigourous validation method. Examination of test responses for discrepant instances yielded further information of value. Hierarchical patterns of learning and remembering are identical. (Author/CP)

This article describes a series of experiments concerning the relationship between cognitive processes and learning a second language. Similarities and differences between first language acquisition and second language learning by children and adults are discussed. (CFM)

A group of concerned educators evaluates the well-publicized arguments for teaching students to be culturally literate. They argue that content and process instruction are inseparable and that teacher preparation and student assessment should both reflect a more thoughtful fusion of content and process. (TE)

Noting the use of mental pictures to aid students' learning--the keyword method--is effective for both good and poor readers, describes specific methods, provides research to support their use, and presents classroom applications that lead from teacher instruction to students' independent learning. (NH)

Interrelationships among metamemory, intelligence, attributional beliefs, self-concept, and strategy use were investigated in 102 German and 91 American children. Some were trained to use a cluster-rehearsal strategy on a Sort Recall task. Post-training assessments tested maintenance, near-transfer, and task-related metamemorial knowledge.…

Investigates the extent to which learning disabled readers' atypical encoding relates to their deficiencies in semantic memory by comparing learning disabled and nondisabled readers in two age groups on dichotic listening tasks that included orienting and nonorienting instructions. (HOD)

A paired-associate memory task with pictures and words as items was used to categorize fourth graders into four learner types (high/low picture x high/low word performance). Poor paired-associate learners profited more than did good paired-associate learners from picture aids on the prose task. (Author/BW)

Multiple-choice tests such as the Force Concept Inventory (FCI) provide useful instruments to probe the distribution of student difficulties on a large scale. However, traditional analysis often relies solely on scores (number of students giving the correct answer). This ignores what can be significant and important information: the distribution…
