Girls' and Boys' Enrollments in Theoretical Math Courses: A Longitudinal Study

Students (n = 331) extensively tested in their first year of high school were followed up as seniors to see what courses in theoretical mathematics they had elected. Discriminant analyses for girls and boys were performed on the test scores, postdicting those who elected two, three or four years of theoretical math. Scores included math achievement (Test of Academic Progress), vocabulary (Quick Word Test), and the Fennema-Sherman Mathematics Attitudes Scales. For girls, the standardized weights of the discriminant function were highest for spatial visualization, vocabulary, perceived Usefulness of Mathematics, and Confidence in Learning Mathematics; for boys, Confidence in Learning Mathematics, math achievement, stereotyping Math as a Male Domain and Effectance Motivation in Mathematics were highest in discriminating those who had elected two, three, or four years of theoretical math.     

What mediates the impact of response alternatives on frequency reports of mundane behaviors?

Previous research demonstrated that respondents assume that the range of precoded response alternatives reflects the researcher's knowledge of the distribution of opinions or behaviours in the population. This assumption may influence respondents' reports in two ways: respondents may either use the range of the response alternatives as a frame of reference in estimating their own behavioural frequencies, or they may be reluctant to report frequencies that appear extreme in the context of the scale. Three experiments using reports of mundane behaviours, namely watching TV and drinking beer, were conducted to differentiate between the frame of reference and the self-presentation hypothesis. The results of all studies favour the frame of reference hypothesis, and suggest that the impact of response alternatives is the more pronounced the less episodic information about the behaviour is accessible in memory. Specifically, proxy-reports were found to be more affected by the range of response alternatives than self-reports (Experiments 1 and 2), and respondents with dispositionally low access to self-related information were found to be more affected than respondents with dispositionally high access to self-related information (Experiment 3). Implications for questionnaire construction are discussed.     

Self-affirmation versus self-consistency: a comparison of two competing self-theories of dissonance phenomena

High or low self-esteem individuals participated in a role-playing paradigm in which a friend stood them up for a dinner date. The participants received either a good explanation from the friend for the missed date (sufficient justification) or a poor explanation (insufficient justification). As predicted by self-affirmation theory (Steele, 1988), but not self-consistency theory (Aronson, 1999), low-esteem participants derogated the friend more than high-esteem participants under both insufficient and sufficient justification. Also supporting self-affirmation theory, sufficient/low-esteem participants reported more offense for being stood-up than sufficient/high-esteem participants. Discussion centers on the role of self-esteem in dissonance processes and on the need for more research that focuses on dissonance/self-threats that result from the behavior of other(s) rather than one’s own behavior.     

Alexander F. Chamberlain: A life’s work

This article examines the life and work of Alexander Francis Chamberlain. Though he has received little attention since the early 1900s, the importance of this scholar should not be underestimated. Chamberlain made notable contributions to the body of knowledge in anthropology—a discipline that, at the time, was a combination of anthropological and psychological inquiry. His early work began with investigations into the cultures and languages of two Indian tribes indigenous to Canada and the northern United States and, within a few decades, positioned Chamberlain as the leading scholar in this domain. Beyond his ethnographic insights, Chamberlain queried the development of the child and wrote on the subject of childhood in world folklore. He concerned himself with a scope of worthwhile subjects ranging from linguistics to women’s suffrage. No topic was out of range as all forms of human study addressed the need for seeing each group as a contributing force to humanity at large. Chamberlain emphasized that no single racial, ethnic, or religious group should be singled out as inherently superior to another, a belief far ahead of his time. This article is an attempt at drawing a picture of a man whose scholarly achievements and strength of character are captured in the depth and breadth of his writing.

Integrity of Literature on Expressed Emotion and Relapse in Patients with Schizophrenia Verified by a p‐Curve Analysis

There is growing concern that much published research may have questionable validity due to phenomena such as publication bias and p‐hacking. Within the psychiatric literature, the construct of expressed emotion (EE) is widely assumed to be a reliable predictor of relapse across a range of mental illnesses. EE is an index of the family climate, measuring how critical, hostile, and overinvolved a family member is toward a mentally ill patient. No study to date has examined the evidential value of this body of research as a whole. That is to say, although many studies have shown a link between EE and symptom relapse, the integrity of the literature from which this claim is derived has not been tested. In an effort to confirm the integrity of the literature of EE predicting psychiatric relapse in patients with schizophrenia, we conducted a p‐curve analysis on all known studies examining EE (using the Camberwell Family Interview) to predict psychiatric relapse over a 9‐ to 12‐month follow‐up period. Results suggest that the body of literature on EE is unbiased and has integrity, as there was a significant right skew of p‐values, a nonsignificant left skew of p‐values, and a nonsignificant test of flatness. We conclude that EE is a robust and valuable predictor of symptom relapse in schizophrenia.     

Noncontingent reinforcement for the treatment of severe problem behavior: An analysis of 27 consecutive applications

Noncontingent reinforcement (NCR) is a commonly used treatment for severe problem behavior displayed by individuals with intellectual and developmental disabilities. The current study sought to extend the literature by reporting outcomes achieved with 27 consecutive applications of NCR as the primary treatment for severe problem behavior. All applications of NCR were included regardless of treatment outcome to minimize selection bias favoring successful cases. Participants ranged in age from 5 to 33 years. We analyzed the results across behavioral function and with regard to the use of functional versus alternative reinforcers. NCR effectively treated problem behavior maintained by social reinforcement in 14 of 15 applications, using either the functional reinforcer or alternative reinforcers. When we implemented NCR to treat problem behavior maintained by automatic reinforcement, we often had to add other treatment components to produce clinically significant effects (five of nine applications). Results provide information on the effectiveness and limitations of NCR as treatment for severe problem behavior.
