Children's attributions of intentions to an invisible agent

Children ages 3-9 years were informed that an invisible agent (Princess Alice) would help them play a forced-choice game by "telling them, somehow, when they chose the wrong box," whereas a matched control group of children were not given this supernatural prime. On 2 unexpected event trials, an experimenter triggered a simulated unexpected event (i.e., a light turning on/off; a picture falling), and children's behavioral response to these events (i.e., moving their hand to the opposite box) was coded. Results showed a significant Age GroupxExperimental Condition interaction; the only children to reliably alter their behavior in response to the unexpected events were the oldest children (M=7 years 4 months), who were primed with the invisible agent concept. For children's posttest verbal explanations, also, only these children saw the unexpected events as being referential and declarative (e.g., "Princess Alice did it because I chose the wrong box"). Together, these data suggest that children may not regularly begin to see communicative signs as embedded in unexpected events until they are around 7 years of age.     

Prawn-in-a-tube procedure: habituation or associative learning in cuttlefish?

The prawn-in-a-tube procedure (J. B. Messenger, 1973a) has been used almost exclusively to study associative learning in cuttlefish. In two experiments, the authors sought to determine whether the decline in attack responses observed in this procedure was best accounted for by habituation or associative learning. Results of Experiment 1 revealed an asymmetrical stimulus-specificity effect that could be interpreted as either an instance of habituation or of associative learning. Results of Experiment 2 demonstrated that the response decline could not be reversed following the presentation of a dishabituatory stimulus. The combined results of these experiments support the conclusion that the response decline is best viewed as a resulting of associative processes. The authors considered whether the response decline represents extinction or passive avoidance.     

Diagnosis and prevention of atherosclerotic cerebral infarction

Atherosclerotic disease accounts for approximately 25% of ischemic strokes. Atherosclerotic stroke is caused mainly by embolic events from the carotid artery bifurcation or the aortic arch, although intracranial thrombosis can occur, more often in African Americans, Asians, and diabetes patients. Primary prevention of stroke is critical for patients with risk factors for atherosclerosis, including hypertension, diabetes, smoking and hypercholesterolemia. Stroke can be prevented in patients with established atherosclerotic disease by identification and management of patients with carotid artery stenosis by non-invasive testing. Particular attention must be paid to patients with transient symptoms of brain ischemia.     

Linking Religious Upbringing to Young Adult Moral Formation

Recent scholarship has conceptualized morality in terms of multidimensional, intuitive traits that influence what people regard as right or wrong. Ample literature shows that religious factors are closely related to moral traits. However, little research has explored links between religious upbringing and adult moral outcomes. This study uses longitudinal data from the National Study of Youth and Religion to examine how diverse forms of religious socialization in adolescence are related to two well-validated social-scientific conceptions of morality in young adulthood: Haidt's moral foundations and Schwartz’ values typology. Using regression analyses and Lindeman, Merenda, and Gold (LMG) decomposition methods, I show that different aspects of religious upbringing are linked to the development of both moral foundations and values. Religious factors play a stronger role than either sociodemographics or parent political ideology in predicting young adult moral characteristics. Results highlight the centrality of religious upbringing to the state and trajectory of the population-level moral structure.     

Relatives Children Say

In an experiment designed to elicit restrictive relatives clauses, 28 children ranging in age from 2:2 to 3:10 provided a corpus of communicatively appropriate relative clauses. In evaluating this corpus, we found that most children produced mostly adult relative clauses most of the time. Detailed study of these utterances uncovered a few error patterns, which we analyzed in light of several considerations (e.g., the overall frequency of an error type, its distribution across children and items, its relation to the construction under study, and the similarity of the error to what children do elsewhere). Only one error pattern, namely some children's production of inappropriate relative pronouns, is argued to reflect a systematic feature of language development. We conclude that children's ability to represent the syntactic structure of the embedded clause is on target very early.     

Effects of Applicant's Adverse Medical History on College Students' Ratings of Job Applications1

The purpose of this experiment was to determine if the existence of high blood pressure or allergies would decrease the likelihood of a person obtaining a job. Forty-eight college students rated hypothetical job applicants with allergies, high blood pressure, or no adverse physical condition for either a high-stress manager trainee position or a low-stress bookkeeper position. For the manager trainee position, applicants with either high blood pressure or allergies were rated significantly lower than the applicants with no adverse physical condition. For the bookkeeper position there were no significant differences between the ratings of the individuals with the different physical conditions. These results suggest that any adverse physical condition may have a negative prototype associated with it; however, a job applicant's physical condition may have different consequences depending upon the type of job for which he/she is applying. The effect of the stress level of the different jobs on the ratings was discussed.     

Anxiety disorders in African-American and white children

There are little available data on African-American children with anxiety disorders. Treatment-seeking African-American (n=30) and white children (n=139), with a current DSM-III-R anxiety disorder, were compared on sociodemographic background variables, clinical characteristics, and lifetime rates of specific DSM-III-R anxiety disorders. Overall, results suggested that the anxiety-disordered African-American and white children who sought treatment from an outpatient mental health facility were more similar than different. The two groups did, however, differ somewhat on several variables (trend only), including rates of school refusal, severity of primary anxiety disorder, lifetime prevalence of posttraumatic stress disorder, and total scores on the Fear Survey Schedule for Children-Revised. More specifically, white children were more likely to present with school refusal and higher severity ratings, while African American children were more likely to have a history of posttraumatic stress disorder and score higher on the FSSC-R. The impact of these findings and the need for additional research are discussed.This study was supported in part by MH grant 40021 from the National Institute of Mental Health.     

Congruence and temporal stability of multimiethod profiles: A new pair of personality variables

Congruence and temporal stability of multimethod profiles within the individual subject were studied as proposed new personality variables in a pool of seven small groups of graduate students in clinical psychology (N= 51) Sex differences were minimal A Stability Index was derived from (a) Q correlation stability coefficients obtained from the single method profiles of an inventory, self-ratings, and mean ratings by others, or (b) absolute difference scores between the composite profiles on occasion 1 and occasion 2 A Congruence Index was derived from (a) Q correlation coefficients obtained from each pair of profiles measured by the three methods for each subject, or (b) mean absolute difference scores obtained from each pair of method profiles These moderately correlated indices were used as dependent variables in stepwise multiple regression analyses, in which scores on a profile of 21 personality variables served as independent variables Although the difference score method was at least as effective as the correlational method in predicting congruence, the Q correlational method was superior in all other analyses conducted in this study Persons high in temporal stability seem to maintain an intellectually searching and interpersonally affiliative approach to the environment, showing little hostility and little tendency to seek change in current life circumstances The highly congruent individual seeks a positive nurturant interaction with other persons, gains pleasure from both sensory and interpersonal experiences, and shows little discontent with present life circumstances
