Turn left where you felt unhappy: how affect influences landmark-based wayfinding

The present work investigated the impact of affect in landmark-based wayfinding. We assumed that affect-laden landmarks improve wayfinding performance and have an impact on later landmark recognition. To investigate our hypotheses, we ran two experiments in a virtual maze. In Experiment 1, we investigated how affect-laden landmarks influence wayfinding and recognition in comparison with neutral landmarks. The aim of Experiment 2 was to focus on the affective valence of a landmark. The memory tasks of both experiments were repeated after 1 week in order to assess memory consolidation. Results showed that the best wayfinding and recognition performance occurs when negatively laden landmarks were used. In comparison with neutral and positively laden landmarks, recognition performance hardly decreased over time for the negatively laden landmarks. Our results not only support findings in the field of emotion research but also expand the concept of semantic landmark salience with respect to emotional responses.     

Toward an International Rule of Law: Distinguishing International Law-Breakers from Would-Be Law-Makers

An interesting fact about customary international law is that the only way you can propose an amendment to it is by breaking it. How can that be differentiated from plain law-breaking? What moral standards might apply to that sort of international conduct? I propose we use ones analogous to the ordinary standards for distinguishing civil disobedients from ordinary law-breakers: would-be law-makers, like civil disobedients, must break the law openly; they must accept the legal consequences of doing so; and they must be prepared to have the same rules applied to them as everyone else.     

Relative quantity judgments in South American sea lions (<Emphasis Type="Italic">Otaria flavescens</Emphasis>)

There is accumulating evidence that a variety of species possess quantitative abilities although their cognitive substrate is still unclear. This study is the first to investigate whether sea lions (Otaria flavescens), in the absence of training, are able to assess and select the larger of two sets of quantities. In Experiment 1, the two sets of quantities were presented simultaneously as whole sets, that is, the subjects could compare them directly. In Experiment 2, the two sets of quantities were presented item-by-item, and the totality of items was never visually available at the time of choice. For each type of presentation, we analysed the effect of the ratio between quantities, the difference between quantities and the total number of items presented. The results showed that (1) sea lions can make relative quantity judgments successfully and (2) there is a predominant influence of the ratio between quantities on the subjects’ performance. The latter supports the idea that an analogue representational mechanism is responsible for sea lions’ relative quantities judgments. These findings are consistent with previous reports of relative quantities judgments in other species such as monkeys and apes and suggest that sea lions might share a similar mechanism to compare and represent quantities.     

The Relationship of Differentiation,Family Coping Skills,and Family Functioning with Optimism in College-Age Students

The marriage and family therapy (MFT) field would benefit from new research about positive subjective experiences, such as optimism, in order to construct and nurture strengths for developing more positive emotions. Through a better understanding of optimism, marriage and family therapists (MFTs) can explore which strategies might help families and individuals better cope with distressing emotions by building buffering strengths. In this study we address the relationship of differentiation, family coping, and family functioning to optimism. We found that differentiation, family coping, and family functioning each have a significant effect on attributional style. The results of this study also indicated that encouraging clients to take an I-position and to reframe problems, in particular, may lead to greater optimism. This study contributes to the lack of research regarding strength-based theories in the MFT field.     

Semantic interference in a delayed naming task: evidence for the response exclusion hypothesis

In 2 experiments participants named pictures of common objects with superimposed distractor words. In one naming condition, the pictures and words were presented simultaneously on every trial, and participants produced the target response immediately. In the other naming condition, the presentation of the picture preceded the presentation of the distractor by 1,000 ms, and participants delayed production of their naming response until distractor word presentation. Within each naming condition, the distractor words were either semantic category coordinates of the target pictures or unrelated. Orthogonal to this manipulation of semantic relatedness, the frequency of the pictures' names was manipulated. The authors observed semantic interference effects in both the immediate and delayed naming conditions but a frequency effect only in the immediate naming condition. These data indicate that semantic interference can be observed when target picture naming latencies do not reflect the bottleneck at the level of lexical selection. In the context of other findings from the picture-word interference paradigm, the authors interpret these data as supporting the view that the semantic interference effect arises at a postlexical level of processing.
