Social influence in investigative interviews: The effects of authority on informational elements produced in interviews and written statements

This study examined the effect of a principle of social influence—authority—on the informational elements in an investigative interview. Community participants told the truth or lied about a mock crime in a high or low authority context. Informational elements were coded from their oral responses in the interviews and written responses in a statement prior to the interviews. Rapport was rated by the interviewers and participants. The authority condition produced effects on the informational elements in both the interviews and written statements but mainly for truth tellers. Rapport also had direct effects on the informational elements but authority did not affect rapport and rapport did not mediate the effect of authority on the informational elements. These findings had theoretical, empirical, and practical implications.     

Context-dependent olfactory learning in an insect

We studied the capability of the cricket Gryllus bimaculatus to select one of a pair of odors and to avoid the other in one context and to do the opposite in another context. One group of crickets was trained to associate one of a pair of odors (conditioned stimulus, CS1) with water reward (appetitive unconditioned stimulus, US+) and another odor (CS2) with saline solution (aversive US, US-) under illumination and to associate CS1 with US- and CS2 with US+ in the dark. Another group of crickets received training of the opposite stimulus arrangement. At 1 d after the training for 3 d, the former group significantly preferred CS1 over CS2 under illumination but preferred CS2 over CS1 in the dark, and the latter group exhibited the opposite odor preference. The results of control experiments showed that the background light condition had no significant effects on memory formation or retrieval unless it was explicitly associated with US during training. Thus, the visual context affected learning performance only when crickets were requested to use it to disambiguate the meaning of CSs and to predict USs.     

Gender differences in judgments of multiple emotions from facial expressions

The authors tested gender differences in emotion judgments by utilizing a new judgment task (Studies 1 and 2) and presenting stimuli at the edge of conscious awareness (Study 2). Women were more accurate than men even under conditions of minimal stimulus information. Women's ratings were more variable across scales, and they rated correct target emotions higher than did men.     

Language-dependent access to autobiographical memory in Japanese-English bilinguals and US monolinguals

Japanese bilinguals retrieved autobiographical memories in response to 20 English and 20 Japanese cue words. US monolinguals were cued with 40 English words. All participants reported one earliest memory. Japanese bilinguals retrieved more memories and earlier memories when cued with Japanese words. They also retrieved more memories when the cue language matched either the language of memory encoding or the language of first thought. Although English cues elicited equivalent numbers of English and Japanese memories in the more fluent speakers of English, Japanese words elicited significantly larger numbers of Japanese memories in all Japanese-English bilinguals. The average age of cued autobiographical memories was significantly earlier for US than for Japanese students but age of the earliest memory did not differ.     

An empirical test of formal equivalence between Emmert's law and the size-distance invariance hypothesis

Emmert's law and the size-distance invariance hypothesis have been said to be formally equivalent, provided that Emmert's law means that the perceived size of an afterimage is proportional to the perceived distance of the projected surface of the afterimage. However, there have been very few studies that have attempted to verify this formal equivalence empirically. We measured both the perceived size and distance of afterimages and real objects with the same proximal size. Nineteen participants projected afterimages of 1 deg in visual angle on the wall located at distances of 1 to 23 meters from the participants. They also observed real objects, disc-shaped and made from a sheet of Styrofoam board, with the same proximal size as that of the afterimages, which were located at the same physical distances as those of the wall on which the afterimages were projected. Each participant reproduced the apparent sizes of the afterimages and real objects using the reproduction method and estimated the apparent distances using the magnitude estimation method. When the mean apparent sizes of the afterimages and real objects, represented as a function of apparent distance, were fitted to a linear function, the slopes for the afterimages and real objects did not differ significantly. These results are interpreted as evidence for the formal equivalence of Emmert's law and the size-distance invariance hypothesis.     

The thrill of victory and the agony of defeat: spontaneous expressions of medal winners of the 2004 Athens Olympic Games

Facial behaviors of medal winners of the judo competition at the 2004 Athens Olympic Games were coded with P. Ekman and W. V. Friesen's (1978) Facial Affect Coding System (FACS) and interpreted using their Emotion FACS dictionary. Winners' spontaneous expressions were captured immediately when they completed medal matches, when they received their medal from a dignitary, and when they posed on the podium. The 84 athletes who contributed expressions came from 35 countries. The findings strongly supported the notion that expressions occur in relation to emotionally evocative contexts in people of all cultures, that these expressions correspond to the facial expressions of emotion considered to be universal, that expressions provide information that can reliably differentiate the antecedent situations that produced them, and that expressions that occur without inhibition are different than those that occur in social and interactive settings.     

The effects of incidental anger,contempt, and disgust on hostile language and implicit behaviors

Recent studies have suggested that the combination of the emotions anger‐contempt‐disgust (ANCODI) is associated with intergroup hostility. This study examined if incidental elicitation of this emotion combination causally produces hostile cognitions, language, and behaviors. Members of political groups were primed with either ANCODI, fear + sadness, or no emotion, and then engaged in creativity task in relation to their opponent or a non‐opponent outgroup. The ANCODI mix produced more hostile cognitions, language, and implicit behaviors associated with hostility, in some cases specifically toward their opponent outgroups, than individuals primed with other emotions. Multiple mediation analyses indicated that the three emotions and their interactions mediated many of the effects.     

Ethnic differences in affect intensity,emotion judgments,display rule attitudes,and self-reported emotional expression in an American sample

Research of the past two decades has shown that cultures exert considerable influence over emotion. Most, if not all, of the cross-cultural research reported to date have been on samples obtained in different countries. Although it is important to address questions of cross-cultural similarities and differences via the testing of between-country differences, we need to be concerned with possible cultural differenceswithin countries as well. The assessment of cultural differences within countries would have implications for not only our conceptual understanding of cultural influences on emotion, but also our empirical methods and procedures. In this study, American subjects were self-classified into one of four ethnic groups, and provided us with data concerning affect intensity, display rule attitudes, self-reported emotional expression, emotion labeling, and intensity ratings. The results indicated considerable differences in emotion judgments, display rules, and self-reported emotional expressions as a function of ethnicity within an American sample. The differences are discussed in terms of the need to search for psychologically meaningful and relevant definitions of culture which would cut across ethnicity or country.     

Confusions about context in the judgment of facial expression: A reply to “the contempt expression and the relativity thesis”

A recent study of the effect of context in the judgment of contempt facial expression (Russell, 1991) was flawed by several confusions about what constitutes context. We argue that the context used should have ecological validity, through the use of many, rather than a few, facial expressions, which are spontaneous rather than posed, and which are judged by carefully selected judgment tasks, using clearly defined or well-understood emotional terms. The confusion in Russell's work between accuracy studies and agreement studies is also addressed.Paul Ekman's work is supported by a Research Scientist Award from the National Institute of Mental Health (MH 06092).

Global Collaborative Team Performance for the Revision of the International Classification of Diseases: A Case Study of the World Health Organization Field Studies Coordination Group

Background/Objective: Collaborative teamwork in global mental health presents unique challenges, including the formation and management of international teams composed of multicultural and multilingual professionals with different backgrounds in terms of their training, scientific expertise, and life experience. The purpose of the study was to analyze the performance of the World Health Organization (WHO) Field Studies Coordination Group (FSCG) using an input-processes-output (IPO) team science model to better understand the team's challenges, limitations, and successes in developing the eleventh revision of the International Classification of Diseases (ICD). Method: We thematically analyzed a collection of written texts, including FSCG documents and open-ended qualitative questionnaires, according to the conceptualization of the input-processes-output model of team performance. Results: The FSCG leadership and its members experienced and overcame numerous barriers to become an effective international team and to successfully achieve the goals set forth by WHO. Conclusions: Research is necessary regarding global mental health collaboration to understand and facilitate international collaborations with the goal of contributing to a deeper understanding of mental health and to reduce the global burden of mental disorders around the world.
