Tomboys and sissies: Androgynous children?

Psychological studies of masculinity-femininity in children have paralleled those done with adults, which often consider deviations from masculinity for males and femininity for females as abnormal and perhaps pathological. Children who demonstrate cross-sex behaviors, however, may become androgynous adults whose cross-sex behaviors mean flexibility, not pathology. This study had two purposes: (1) to identify potentially androgynous children as those labeled by their peers as tomboys and sissies; (2) to compare personality characteristics of androgynous children with those of peers. Subjects were 312 elementary school children in a midwestern city. Results indicate that the labels tomboy and sissy are not necessarily indicators of androgynous children, but important social behaviors are related to the labels. For males, the possibility of frustrated creativity was raised.     

The Generalized Quantum Episodic Memory Model

Recent evidence suggests that experienced events are often mapped to too many episodic states, including those that are logically or experimentally incompatible with one another. For example, episodic over‐distribution patterns show that the probability of accepting an item under different mutually exclusive conditions violates the disjunction rule. A related example, called subadditivity, occurs when the probability of accepting an item under mutually exclusive and exhaustive instruction conditions sums to a number >1. Both the over‐distribution effect and subadditivity have been widely observed in item and source‐memory paradigms. These phenomena are difficult to explain using standard memory frameworks, such as signal‐detection theory. A dual‐trace model called the over‐distribution (OD) model (Brainerd & Reyna, 2008) can explain the episodic over‐distribution effect, but not subadditivity. Our goal is to develop a model that can explain both effects. In this paper, we propose the Generalized Quantum Episodic Memory (GQEM) model, which extends the Quantum Episodic Memory (QEM) model developed by Brainerd, Wang, and Reyna (2013). We test GQEM by comparing it to the OD model using data from a novel item‐memory experiment and a previously published source‐memory experiment (Kellen, Singmann, & Klauer, 2014) examining the over‐distribution effect. Using the best‐fit parameters from the over‐distribution experiments, we conclude by showing that the GQEM model can also account for subadditivity. Overall these results add to a growing body of evidence suggesting that quantum probability theory is a valuable tool in modeling recognition memory.

Invitation to murder

In the Hebrew Bible, hospitality creates social capital, forges alliances and marriages and is used as a literary tool to characterize both people and deities. Hospitality is also described as a high-risk, high-gain type of social practice because it renders both the guest and the host vulnerable to aggression and violence. This article explores the relationship between hospitality and violence in the Hebrew Bible, represented by the murder of Amnon at Absalom’s sheep-shearing feast in 2 Samuel 13 and the murder of Sisera in Judges 4. These texts seem to go directly against an ideal that is expressed elsewhere in the Hebrew Bible, namely that a guest is sacred and entitled to protection (e.g. Gen 18 and 19).     

Historical Analogies and the Definition of Interests: The Iranian Hostage Crisis and Ronald Reagan's Policy Toward the Hostages in Lebanon

Students of political psychology have long shown an interest in exploring how analogical reasoning affects decision-making. However, the existing literature on analogical reasoning has remained within the rationalist explanatory framework by assuming that an actor's interests can be deduced from that actor's position in a certain material structure, thus treating those interests as unaffected by the process of analogical reasoning. This assumption unduly restricts the role that analogies may play. Analogies can do more than simply allow decision-makers to figure out what specific policies will advance their preexisting interests—they can also determine the interests themselves. To demonstrate the benefits of moving the analogical literature beyond rationalism, this article explores the Reagan administration's policy toward American hostages in Lebanon, which culminated in the Iran-Contra scandal.     

Integrating episodic memories and prior knowledge at multiple levels of abstraction

Prior knowledge can have a large influence on recall when the memory for the original event is error prone or incomplete. We investigated the interaction between memory and prior knowledge in a recall task involving natural objects such as fruits and vegetables. We first quantified prior knowledge for the sizes of objects in a norming experiment. We then assessed the influence of prior knowledge in a memory experiment in which we compared the actual size of objects shown during a study phase with the reconstructed size of an object during the test phase. Recall was biased both by the mean size of the specific object studied and by the mean size of all objects in the category. This result suggests that the influence of prior knowledge can come from multiple, hierarchically related levels of representation, such as the object-category and superordinate-category levels.
