Offline and online automatic number comparison

This paper focuses on automatic number processing as instantiated in the size congruity effect. It was recently argued that long-term "associations between individual digits and the attributes 'small' and 'large' create the size congruity effect" (Choplin and Logan 2003, abstract, p. 17). Moreover, these authors proposed the additional assumption that the relevant connections are acquired over a lifetime of experience with numbers. We show that at least one of these assumptions is not true: either the size congruity effect derives from an (online) comparison effect between two numbers at the time of stimulus presentation (violating the first assumption) or the relevant connections flexibly change (offline) between trials during the course of one experimental session (violating the second assumption).     

When socially excluded people prefer moralizing to anti- and prosocial behavior: Support for a goal-directed account

According to the temporal need-threat model, different responses toward social exclusion stem from the fact that different needs are threatened. Because evidence for this account is mixed, we tested a goal-directed account in which the chosen behavior depends not only on the threatened need but also on the behavior that has the highest expectancy of repairing that need. In two experiments, participants were excluded using the cyberball paradigm. They were then either assigned to a condition in which they could choose to send aggressive or prosocial messages to the other players or to a condition in which they could send aggressive, prosocial, or moralizing messages. We hypothesized that the expectancy to repair threatened needs would be higher for moralizing behavior than for aggressive and prosocial behavior, which would result in moralizing behavior in the second condition. Both experiments provided partial support for our hypothesis, suggesting that the reactions to social exclusion might be goal directed.

     

FUNCTIONAL ANALYSIS OF SEPARATE TOPOGRAPHIES OF ABERRANT BEHAVIOR

We conducted a functional analysis of distinct topographies of aberrant behavior displayed by 4 clients. We first analyzed the behaviors in an aggregate fashion and then separated the behaviors to formulate hypotheses about the maintaining variables for each behavior. The procedures were used in a two-phase experiment. During Phase 1, two extended functional analyses were completed, one in an inpatient unit and one in a special education classroom. During Phase 2, two brief functional analyses were completed in an outpatient clinic. Results indicated that hypotheses of separate functions for distinct behaviors can be generated using both extended and brief functional analyses when the results are graphed in the aggregate and are separated by response topography. The results also suggest that these methods can improve the accuracy of data interpretation and treatment selection.     

Toward a Psychology of Resistance

Resistance is all around us in contemporary life. It is an everyday phenomenon of personal and cultural life, as the Chaudhary et al. (2017) volume establishes with theoretical analyses and empirical examples from diverse cultural contexts. Resistance functions in the dynamics of person-by-culture encounters when one party takes an opposing position. With the purpose of working towards a unified approach to resistance, the authors in this volume lay down the foundations for a psychology of resistance as an everyday phenomenon. As a basis for analyzing the role of resistance in the dialectical processes of change, the volume presents resistance as: personal and social, oppositional, intentional and future-oriented, transformational and developmental. We see different positions opening up a debate about whether resistance is a particular, intentional and oppositional phenomenon, or is the basic process of all dialectical transformational change. Further resistance to either position is consistent with moving forward in the development of a psychology of resistance.     

Mathematics Participation and Mathematics Achievement Across Secondary School: The Role of Gender

The present study investigated whether the relationship between mathematics participation and mathematics achievement is reciprocal for boys and girls. In Years 1, 2, 4 and 6 (US grades 7, 8, 10 and 12), we administered mathematics achievement tests to a cohort of 1,495 Flemish students and collected data on the number of classroom hours allocated to mathematics. A cross-lagged panel design was used to analyze the data. Evidence was found for a reciprocal relationship between mathematics participation and mathematics achievement, particularly in Years 4 and 6 (US grades 10 and 12). The results suggest that boys’ better performance in mathematics is related to their higher participation in math, whereas other factors—in addition to gender differences in math achievement—play a role in explaining why boys participate more in mathematics than girls.     

Memantine facilitates memory consolidation and reconsolidation in the day-old chick

Memantine is a non-competitive N-methyl-d-aspartate (NMDA) receptor antagonist that has been approved for the treatment of the cognitive deficits noted in Alzheimer's disease. While there is a body of research that supports memantine's facilitative action upon memory compromise, this series of studies aimed to investigate the effects of this drug in healthy animals with intact memory functioning. A 0.1 mM dose of memantine injected immediately after a weakly aversive training event (i.e. 20% v/v methyl anthranilate) was found to enhance passive avoidance learning for this event in day-old chicks up to 24 h following training. The same dose of memantine was also observed to enhance memory for the training event when it was administered in conjunction with a reminder trial. These results suggest that memantine is capable of facilitating both memory consolidation as well as memory reconsolidation. It was concluded that memantine's mechanism may involve the short-term or intermediate memory phases of the Gibbs and Ng model of memory, and that the current findings represent enhancement of intact memory, rather than amelioration of memory compromise.
