Memory for noun pairs in the same or different underlying strings

A number of studies have shown that children learn noun pairs faster when they have been presented in a noun-verb-noun context than when they are presented in a noun-conjunction-noun context. Suzuki and Rohwer (1969) hypothesized that the underlying strings of sentences correspond to memory units, making it easier to recall two nouns from the same underlying string than from two different underlying strings. They reported that data from fifth graders supported this hypothesis but that data from college students did not. The experiments reported here were done to determine whether the hypothesis would be supported (a) if the test rate were faster than that used by Suzuki and Rohwer or (b) if sentences longer and more complex than those used by them were employed. The recall data accorded with some predictions derived from the hypothesis. However, data from Ss’ posttraining reports on how they learned the pairs suggest that Ss, particularly adults, often made up their own strings rather than using those provided, and raise the question of the adequacy of Suzuki and Rohwer’s procedure for testing this hypothesis, particularly in adults.     

Gender differences in the relationship between hostility and the type A behavior pattern

A group of 97 male and 111 female undergraduates completed the Jenkins Activity Survey, the Framingham Type A Scale, the Adjective Checklist Type A Scale, the Spielberger State-Trait Anxiety Inventory, and the Buss-Durkee Hostility Inventory. A factor analysis revealed three dimensions: Anger-Emotionality, Anger-Aggression, and Residual Pattern A. All Type A measures loaded highly on the Type A factor, with the Jenkins Activity Survey loading the highest. The Framingham Type A Scale was related to Anger-Emotionality, the Adjective Checklist Type A Scale was related to Anger-Aggression, and the Jenkins Activity Survey was related to neither of the anger dimensions. Women scored higher than men on Anger-Emotionality and the Guilt, Resentment, and Irritability subscales and lower than men on the Assaultiveness subscale. Women showed higher correlations between Type A and the Guilt subscale, and men between Type A and the Suspiciousness subscale. We conclude that Type A is a multidimensional construct that manifests itself differently in men and women.     

Chronic self-destructiveness: Conceptualization,measurement, and initial validation of the construct

Individual differences in various behaviors suggest that those who are primarily motivated by current emotional factors are more likely than those motivated by more distant cognitive considerations to engage in acts that are ultimately self-destructive. To assess and explore these behavioral differences, 12 samples of undergraduate subjects, totaling 864 (527 females, 337 males), a group of 15 businesswomen, and 111 male VA patients were used to develop a measure of this construct in a series of reliability and construct validity studies. By means of internal-consistency item analyses, two cross-validated 52-item measures of chronic self-destructiveness were constructed for males and females. Reliability was established with respect to internal consistency (alpha coefficients range from .73 to .97) and temporal consistency over a 1-month period (test-retest correlations range from .90 to .98). There is a slight drop in chronic self-destructiveness scores across age groups. Test scores were found to be positively related to external locus of control, negatively related to Type A coronary-prone behavior, and unrelated to either social desirability response set or need for achievement. Individuals high in chronic self-destructiveness, compared to those with low scores, are more likely to be in treatment for drug or alcohol abuse, to report having cheated in courses, to have had traffic violations, to report having gone through a rebellious stage in adolescence, and to postpone obtaining a medical test for cancer. Chronic self-destructiveness appears to be a personality dimension that affects behavior across a wide range of ages and situations.We wish to thank John Wapner for his assistance in obtaining data in the clinical sample.     

Familiarity decisions for faces presented to the left and right cerebral hemispheres

Right-handed subjects were asked to decide whether or not faces presented briefly in the RVF or in the LVF were familiar (familiar faces were those of famous people). This task avoids the need for extensive semantic processing or temporary storage involved in conventional naming or identification tasks, and thus eliminates the contribution of such factors to any observed asymmetry. The resulting finding of faster reaction times to LVF faces, with no overall visual hemifield difference in error rates, is taken to indicate a right-hemisphere superiority either in the processes used to construct facial representations or in the accessing of face recognition units, or both.     

Assessing structure building in college classrooms at scale

Structure building refers to the way in which people construct meaning from incoming information by creating a foundation of mental nodes, mapping incoming information to the foundational structure, and shifting to a new structure when necessary. Structure building ability has been shown to moderate learning both in laboratory-based and classroom-based research (e.g., use of outlines for effective note-taking and course final grades, respectively). However, measurement of structure building can be resource intensive. The purpose of the present study was to evaluate a shortened, scalable measure of structure building (developed by a textbook publisher) in a real-world context. The results are consistent with the hypothesis that this tool, embedded in the online ancillary materials accompanying a textbook, can be used to measure a variable that is relevant to students' learning in introductory psychology courses.
