Visual recognition memory in squirrel monkeys

Squirrel monkeys (Saimiri sciureus) were trained on visual recognition memory tasks in a Wisconsin General Testing Apparatus with a trial-unique procedure that used 250 objects as stimuli. In Experiment 1, acquisition of a trial-unique delayed non-match-to-sample task (DNMS) was compared with acquisition of a trial-unique delayed match-to-sample (DMS) task. The DNMS task was learned in significantly fewer trials and with significantly fewer errors. Two animals in the DNMS group demonstrated highly accurate retention of the DNMS strategy despite an 11-month hiatus in experimental testing. In Experiment 2, the same procedures were used to study the learning of lists of 3, 5, 10, or 20 serially presented items. Although the animals were able to accurately remember lists of up to 20 items, there was no evidence of serial position effects.     

Emotional Determinants of Infant-Mother Attachment

The present study examined the assumption that emotion-related characteristics of mothers and infants contribute to the development of infant-mother attachment in the first year of life. Mothers' emotion and personality characteristics were assessed with expressive-behavior ratings and self-report scales. Infant characteristics were measured by emotion and temperament questionnaires (mother report) and objective coding of facial expressions of emotions. Attachment classifications were determined by means of the Strange Situation procedure, and a continuous-variable index of attachment security was derived by a discriminant function procedure. Mothers' emotion experiences, expressive behaviors, and personality traits were significant predictors of the level of security of the infant-mother attachment. Infants' expressive and temperamental characteristics as rated by their mothers were also significant predictors of attachment security.

A Simple and Effective Program to Increase Faculty Knowledge of and Referrals to Counseling Centers

The authors describe a simple, cost‐effective, and empirically supported program to increase faculty referrals of students to counseling centers (CCs). Incoming faculty members at 3 universities received a mailing and personal telephone call from a CC staff member. Faculty assigned to the outreach program had greater knowledge of and rates of referral to CCs than did faculty who received only standard information at faculty orientation. Recommendations for the implementation of this program are discussed.

The developmental origins of a default moral response: A shift from honesty to dishonesty

People are sometimes tempted to lie for their own benefit if it would not harm others. For adults, dishonesty is the default response in these circumstances. The developmental origins of this phenomenon were investigated between 2019 and 2021 among 6- to 11-year-old Han Chinese children from China (N = 548, 49% female). Children had an opportunity to win prizes in a behavioral economics game (Experiment 1) or a temptation resistance game adapted from developmental psychology (Experiment 2). In each experiment, the youngest children showed a default tendency of honesty and there was an overall age-related shift toward a default tendency of dishonesty. These findings provide direct evidence of developmental change in the automatic and controlled processes that underlie moral behavior.     

Commentary on vocational mathematics education: where mathematics education confronts the realities of people’s work

In this commentary I will address the notions of work, the need for innovation, and the role of workplace mathematics. I will then provide an overview of some of the complex issues that confront the subfield of vocational mathematics education with consequences for current and future workers, drawing in part on the work of Basil Bernstein. Finally, I will address the question of workplace research and offer some possible directions for future research, as well as implications for policy. Reflections on the articles included in this special issue will frame the discussion.
